The present application is based on and claims priority to U.S. Provisional Application No. 61/145,120, filed on Jan. 16, 2009, the disclosure of which is hereby incorporated by reference. This application is also a partial succession application and is based on and claims the priority of US Application No. 12/505,555 filed on July 2, 2009, US Application No. 12/5〇5,555 Part of the continuation of the U.S. Application Serial No. 12/502,237, filed on Jul. 14, 2009, the disclosure of which is incorporated herein by reference. [Prior Art] A variety of handheld or portable lighting devices (including + flashlights) are known in the art. Such illumination devices typically include one or more dry battery packs having a positive electrode and a negative electrode. The battery is electrically configured in series or in parallel in the battery compartment or housing. The battery compartment sometimes also acts as a handle for the lighting device, especially under the flashlight, where the barrel contains the battery and is also used to hold the flashlight. Forming a circuit from the battery electrode via the conductive member, the conductive member being electrically connected to an electrode such as a light source of a bulb or a light emitting diode ("LED"), and after passing through the light source, the circuit continues to pass through the conductive member The second electrode of the light source that is in electrical contact, the conductive member and the other electrode of the battery, includes a switch that _ or a closed circuit. Actuate this to close the circuit so that current can pass through the bulb, coffee or other light source - and 145907.doc 201038127 through the filament under incandescent bulbs. The portable (4) device of the formula 12 is not required to provide a variety of operation modes. =: 'In addition to the normal "full power" or "standard power" mode, the power, mode, and mode have been applied. And / or SOS mode. In these portable lighting devices, the user usually selects the desired lighting device in normal operation by manipulating the user interface (usually the A t π mode of operation. For example, carrying the main switch). ❹ ❹ or in the power-saving mode of operation, by manipulating the main switch to break, = "return" the portable lighting device to turn the portable lighting device into another operating mode 'such as the sos mode. In other devices, the main switch may be required and held for a certain period of time to cause the lighting device to shift to the lower mode of operation. Portable lighting devices including advanced functionality may include electrical control controlled by a microcontroller or microprocessor. City's electronic power switch to provide the desired function = portable lighting device with multiple functions _ potential problem is that the user needs to manipulate the main switch in some way to enter the new operating mode 2, for example, the flashlight barrel body' Then press and release; the sequence of switches can direct the flashlight that is operating away from the intended illumination zone. = The switch is used as a user interface to enter the new mode of operation. The additional sequence is often complex or easily takes too long to guide through different modes of operation. The problem associated with the main switch practice is that the main switch is frequently manipulated to direct premature wear of the mechanical parts of the switch through different modes of operation, thereby shortening the life of the portable lighting device. Therefore, there is a need for a portable lighting device with improved power from the ♦* power surface, which does not require a switch to guide the portable (4) τ-carrying through the portable Various operating modes are available for the lighting device. Flashlights and other portable lighting devices You have used the mechanical power switch in the main power circuit of the flashlight to "connect Γ ^ ^ 筏 」通" and "cut off" the portable device: device. When the user "turns on" the portable lighting device, the user typically presses down or otherwise manipulates the mechanical power switch to mechanically connect the two contacts to close the switch and complete the power circuit, thereby allowing current from the positive terminal of the battery. When passing through the light source and flowing to the negative terminal 1 of the battery to "cut" the portable lighting device, the user again manipulates the mechanical switch to open the two contacts of the switch and thereby open the switch and interrupt the power circuit. The mechanical power supply circuit in such devices thus acts as a conductor when the power supply circuit is completed and thus conducts current throughout the operational sequence of the portable lighting device. Because the mechanical power switches form part of the circuitry of the lighting device, the contacts of such switches tend to be quite heavy. Therefore, such switches tend to require a significant amount of force to close and open their contacts. As a result, it can be difficult to use a portable lighting device having a mechanical power switch as the transmitting device for an extended period of time. For example, between the "on" and "off" positions, the force required for the vertical switch can be fatigued by the user after the extended period of use of the portable lighting device for signaling applications. In addition, with some mechanical power switches, it may be easy to spend too much time closing and disconnecting the mechanical power switch to "on" and "cut off" the portable lighting device 145907.doc 201038127 to perform certain signaling applications. . Another problem with the use of the main switch of the portable lighting device to implement the signalling mode implemented by the user is that the main switch is repeatedly operated to "cut" and then resumes the "on" mode. The mechanical parts of the switch can be premature. Wear and tear, thus shortening the service life of the lighting device. ' ❹

Some of the switches used in portable electronic lighting devices may require less force to operate 'because they typically do not form part of the main power circuit for illumination I and therefore do not act as a heavy load. While this situation is potentially advantageous in signalling applications from the perspective of user fatigue, multi-mode portable electronic devices present their own series of problems for the signaling patterns implemented by the user. For example, in a multi-mode electronic portable illumination I, various operation modes may be resumed by the user (4) illumination device for a period of less than a predetermined period (such as '1 to 2 seconds) and then resumed to be turned on again. Come choose. In response to this brief cut-off period, the lighting device changes to the next mode. Therefore, it is difficult to use the multi-mode portable electronic display device configured in this manner for the signal mode implemented by the user. This is because the user must wait for a period of time greater than the predetermined period of time before restoring the lighting device, otherwise it will automatically switch to the next-operating mode, thereby interfering with the expected episode of the latter. In other words, the user will be prevented from signaling via a short-lived period of light and no light to communicate via, for example, a Moss code. Therefore, there is a need for an improved portable electronic lighting device that can be used for users without having to manipulate mechanical switches to repeat "on" and "cut" lighting devices. Implemented in the signaling mode. 145907.doc 201038127 Compass is suitable for a variety of outdoor sports or hobbies, including (for example) backpacking, hiking, climbing, boating, etc. The conventional magnetic compass includes a magnetic field to indicate the direction of the earth's magnetic north. However, in the dark, it is difficult to see the direction of the magnetic M finger shawl without the light source assisting n brother. In some compasses, the magnet and the surface of the compass are coated with a fluorescent material to improve night vision and use. However, in extremely dark conditions, these fluorescent coatings may not be sufficient. Some advanced compasses are equipped with built-in light sources to be turned on when needed. However, the compasses tend to be more expensive and more likely to be smaller _ U = owned by outdoor enthusiasts. In addition, there are many situations in which an individual will benefit from having a compass but for all reasons not having a compass at all, but it does only have a flashlight or other portable lighting device. Therefore, there is a need for a portable illuminating device such as a flashlight or a headlight to provide a compass function for the portable mascara device. Advantageously, the device can be used during both day and night. Such devices will be suitable for a wide range of individuals, including outdoor enthusiasts and novice outdoorrs. The night lights that are inserted into the wall are well known. However, these night lights are portable, thus providing sufficient security for the night lights required in multiple rooms. - Some people use flashlights or other portable lighting devices as 2 (not more) flashlights or other (4) flashlights or other ° / ',, and monthly devices. However, if the conventional flashlight or portable camcorder is kept on overnight to provide a constant light, the battery may be quickly depleted.

There may be a problem with the location of the device. In some cases, A 145907.doc 201038127 When searching for portable lighting devices, users can determine the location of the lighting and even cause damage, especially in emergency situations. Therefore, there is a need for a portable lighting device that has improved functionality as a night light. In a multi-mode portable electronic lighting device, the electronics of the lighting device can include a number of pre-programmed functions. These modes may include "standard power" mode, power down mode, blink mode, and (10) mode. However, π can adjust various individual modes of such conventional multi-mode devices. Result, can

Multi-purpose portable lighting devices V 0Έ 5H Users must choose the most suitable mode for their needs. The solution to this problem is to program the extra mode of operation into the lighting unit. For example, instead of having a single power reduction mode, the portable lighting device can be provided with two discrete power reduction modes, such as (4) power reduction mode and 5〇% power reduction mode. However, this discrete approach to this problem is not extremely practical, as more time is required to guide through different discrete operations as each new operating mode is added to the squatting '', month device' Mode so even the user will be less likely to use the lighting device

Feature. The user does not provide a practical option for including many modes of operation, such as the 'early switch'. In fact, for some designs, attempts to access in, for example, four or five discrete modes of operation will be numb. Thus there is a need for a multi-mode portable lighting device that implements a user-adjustable mode of operation. Battery power is consumed when a portable lighting device such as a flashlight or headlight is turned on. As a result, if the lighting device is inadvertently kept "on", then 145907.doc 201038127 can be wasted battery power or battery life under dry battery conditions. This type of production unfortunately enables portable lighting devices to have reduced performance when they are actually needed. To alleviate this problem, some portable lighting devices have been provided with an automatic cut-off feature that automatically (4) automatically cuts off the lighting fixture for a predetermined period of time.

However, such battery packs and battery packs often contain a housing that requires multiple threaded fasteners to assemble, resulting in a complicated and expensive battery pack or battery pack. In addition, in the case of a rechargeable battery pack, if any of the electronic devices are used in conjunction with recharging, the electronic devices may not be included in the battery pack. Therefore, additional connections are often required which can increase manufacturing costs and design complexity. & Therefore, there is a need for an improved battery pack in both non-rechargeable and rechargeable situations. SUMMARY OF THE INVENTION A number of portable lighting devices and methods of operation thereof are provided. In general, the portable lighting devices can be any type of portable lighting device including, for example, a flashlight, a headlight, a lantern, and the like.

Operating a portable lighting device such as a flashlight or headlight - a potential method involves moving the lighting device in a first predetermined manner to place the lighting device in a new mode. The method can further include adjusting the mode of operation in the second predetermined direction. For example, the portable lighting device can be rotated in a first direction about the projection axis of the light source to enter a new known mode. In addition, the opposite direction is used to adjust the selected mode around the projection axis. The above method is advantageous in that a new operating mode can be selected with the pressing and releasing sequence of the main switch. Similarly, these methods will also implement the selected mode (4) without implementing the complex press and release sequence of the main switch.

The second circuit board 135 includes circuitry for driving the LEDs 137. In the present embodiment, the second circuit board 135 includes a linear buck regulation circuit to reduce the drive voltage of the lamp module 128 because the electrical waste delivered by the assembled circuit board 24 is significantly higher than the operating voltage of the LED 137. However, in other embodiments, the second circuit board 135 can include a linear boosting adjustment circuit for when the driving voltage of the lamp module 128 is lower than the operating voltage of one or more of the 13 to be driven. The appropriate voltage is provided to the LED i37. In other words, the second circuit board 135 can provide buck or boost operation depending on the load and battery voltage requirements. If the battery voltage is high, a buck operation will be performed. On the other hand, if the battery voltage is low, a boosting operation will be performed. In some embodiments, the buck operation can be performed initially, and the boost operation is provided after the voltage of the battery: drops below a certain level. The lower assembly 141 is preferably formed by co-molding the compressible positive contact 133 and the lower permanent body 129. Similarly, the upper assembly (4) is formed by molding the upper portion, the insulator 145 and the upper positive contact 147, and the upper negative contact (4) together. Therefore, the upper insulator and the lower insulator are preferably formed of an ejectable plastic having a structure and thermal quality suitable for the application. J 耵 145 145 907.doc • 25- 201038127 The upper and lower contacts of the upper assembly 143 are soldered to the bottom of the first circuit board 139, and the front side of the first circuit board 139 is soldered to the contact ring 151. The contact ring 151 can be press fit into the assembly and/or soldered to the heat sink housing 188. Therefore, in the present embodiment, the upper assembly 143 is securely held within the heat sink housing 188. Further, the circumference of the fin case 188 is crimped into the annular recess 161 of the lower insulator 129. Curling the fin housing 188 into the dove recess 161 retains the lower insulator 129 and thus the lower assembly 141 within the fin housing 188. The heat sink housing 188 is thermally coupled and electrically coupled to the light source 101 and the shoulder ring 126 when the flashlight 1 is in an on state. Additionally, the heat sink housing 188 electrically couples the ground path of the second circuit board 135 to the shoulder ring 126. The heat sink housing 188 thus acts as a negative or ground contact for the light module 128. In addition, by configuring the fin housing 188 as shown in FIG. 3 to provide good thermal contact with the shoulder ring 126 (the shoulder ring 126 is more fully explained below and in good thermal contact with the barrel 124), When the flashlight 1〇1 is turned on, the heat generated by the light source ιοί is effectively absorbed and/or dissipated by the first circuit board 139 to the contact ring 151, the heat sink casing 188, the shoulder ring 126, and finally discharged to the The barrel 124. Therefore, the flashlight 1〇1 can effectively protect the light source ιοί from damage due to heat. Preferably, the heat sink housing 188 is made of a good electrical and thermal conductor such as aluminum. The defensive fin housing 1 88 is formed such that it opens from the first region 163 having the first diameter to the second region 167 having the second larger diameter toward the back or bottom of the lamp module m in the region 169 . The diameter of the first region 163 is sized such that the first region can fit tightly within the annular lip 186 of the shoulder ring 126 145907.doc -26 - 201038127 while in thermal contact therewith. The rearward surface of the annular lip 186 forms a contact surface 丨87. The lower insulator i29 and the fin housing 188 are sized to have substantially no play between the inner wall of the shoulder ring 126 and the lower insulator 129 and the fin housing 188 in the radial direction. In this manner, when the lamp module 128 is pushed forward within the shoulder ring 126 sufficiently farther that the flared region 169 of the fin housing 188 contacts the contact surface 187 of the annular lip 186, the fin housing 188 will The taps are not in thermal and electrical contact with the shoulder ring 126 in the first, second and flared regions 163, 167, 169. The outer surface of the fin housing 188 also includes an annular recess 171 in the region 163 of the first diameter. The annular recess m is substantially perpendicular to the heat sink and the shaft of the barrel 124. In addition, the annular recess i 7 is positioned to receive the locking projection 173 of the retaining collar 120 when the lamp module 128 is mounted in the front end of the barrel 124 in the shoulder ring 126 (see FIG. 20A). 〇Q The flared region 1 69 of the heat sink housing 88 is preferably shaped to cooperate with the contact surface 187 along as much surface area as possible to facilitate electrical communication between the light module ι 28 and the shoulder ring 126 And hot connection. The flared region 169 of the heat sink housing 188 is also sized such that once disposed in the shoulder ring 126, the heat sink housing 188 and thus the axial movement of the light module 128 in the forward direction will be by the shoulder ring The annular lip 186 of 126 is limited. The lower insulator 129 includes a recess 178 at its back side 175 that is surrounded by an annular shoulder 179 such that the recess is centrally positioned. The recess 178 is sized to be deeper than the top positive contact 21 of the battery pack 13 145907.doc -27- 201038127 degrees. However, as shown in FIG. 2 and FIG. 3, when the battery pack 130 is advanced against the moon 1 surface of the lower insulator i 29, the top positive contact 214b of the battery pack 13 Engaged with the compressible positive contact 133. In this manner, the light module 128 provides a simple configuration that enhances the assembly even when the flashlight vibrates or falls (which causes the battery pack 130 to suddenly shift axially within the barrel 丨 24) Electrical coupling between. In addition, since the compressible positive contact port 33 can absorb the impact stress due to, for example, erroneous operation and the recess 1 78 is deeper than the top positive contact 214b of the battery pack 130, the flashlight 1 is used. The battery pack 13 and its electronics discussed below are protected from physical damage during the period. And because the compressible positive contact 133 is disposed in front of the shoulder 179 of the back side 175, if the battery pack 13 is inserted backward into the barrel 124, no electrical coupling with the compressible positive contact 133 is formed. . Therefore, the configuration of the lamp module 128 and its configuration within the barrel i 24 will help protect the electronics of the flashlight from reverse currents or damage. The retaining collar 120 is attached to the fin housing 188 of the lamp module 128, and in particular limits the axial movement of the lamp module 128 in the rearward direction when the battery pack 130 is removed from the flashlight 100. The retaining collar 120 is attached to the lamp module 丨28 at the annular recess i7i of the fin housing 186. Referring to Figures 3, 20A and 20B, the retaining collar 12 includes a circumferential lock dog out 173 that projects inwardly from the inner surface of the retaining collar 12; and a rib 181 that retains therefrom The outer surface of the collar 12 向外 protrudes outward. Referring to Fig. 3, each of the locking projections 181 is sized to fit into an annular recess 丨7丨 on the exterior of the stencil fin housing 188. A plurality of ribs 145907.doc • 28· 201038127 The objects m are preferably equally spaced around the outer circumference of the retaining collar 12〇 to extend generally in the axial direction of the retaining collar 120. The ribs 181 preferably extend from the front portion of the retaining collar to slightly more than one half of the length of the retaining collar 12〇. The ribs 181 are sized to limit the amount of radial play between the front end of the lamp module 128 and the inner diameter of the shoulder ring 126 to a desired amount. The ribs 181 are also preferably sized to project outwardly from the retaining collar 12A to a distance equal to or greater than the distance from the inwardly projecting turns of the locking projections 173. By extending only the ribs into the middle of the retaining collar 120, the retaining collar 12's rear end 183 can be fully expanded over the outer surface of the fin housing 188 within the shoulder ring until circumferentially locked The projection 173 is snapped into the annular recess 171 (see FIG. 3). Once the circumferential locking projections 173 are snapped into the annular recess 171, the rearward movement of the light module 128 is defined by the annular lip 186. Therefore, by fastening the retaining collar 120 to the lamp module 128 disposed in the shoulder ring 126, the retaining collar ❹ 12 without the battery pack 13 installed in the flashlight 100 The lamp module 128 is prevented from descending to the rear of the barrel 124 and may fall out from the rear end of the flashlight 100. In the preferred embodiment, the retaining collar 120 is formed from an insulator such as plastic. • Referring to Figure 3', the shoulder ring 26 forms a large heat sink. In addition, because it has a mass that is substantially greater than the mass of the lamp module 128, it quickly diverts the heat sink 149 from the lamp module 128. Finally, the heat drawn by the shoulder ring 126 is efficiently introduced into the barrel 124 because the barrel 124 and the shoulder ring 126 are preferably in close metal in the region 丨89 before the reduced diameter of the shoulder ring 126. Contact with metal. The shoulder ring 126 can be made of metal, and more preferably 145907.doc -29- 201038127 is made of nickel plated to achieve enhanced thermal, electrical, and surname properties. The shoulder ring 126 includes a shoulder 18〇 formed at the interface of the reduced diameter front region 1 89 and the increased immediate post-operation region 191. The front region up includes a plurality of keyways 193' as best seen in Figure 5A. The keyway 193 is preferably equally spaced about the circumference of a portion of the region 189 of the shoulder ring 126 to extend generally axially of the shoulder ring 126. The outer diameter of the front region 189 of the shoulder ring 126 is sized such that it will provide an interference fit with the inner wall of the front portion 125 of the barrel 124 and such that when the shoulder ring 126 is press fit into the portion I25 prior to the barrel 124 The keyway 193 will cut into the inner wall of the barrel portion 1 in the front portion 125. When the shoulder ring 126 is press fit into the front portion 125 of the barrel 124, the keyway 193 will be splayed and cut into the metal on the inner diameter of the portion ι25 before the barrel ι24. The front and rear ends of the keyway 193 adjacent to the shoulder 126 are again shaped to form a metal to accommodate metal from the body 124 displaced during the press-fit assembly operation. In this manner, the shoulder ring is permanently locked in metal-to-metal contact with the portion 125 of the barrel 124. The diameter of the region 191 after the shoulder ring 126 is slightly smaller than the inner diameter of the rear portion of the barrel ι 24 so that it can easily slide within the barrel 124 without damaging any protective coating (such as 'produced by an anodizing process). The above arrangement is also desirable because the keyways 193 will cut open any anodized coating placed on the interior of the barrel 124, thereby providing for the use of the barrel as described, for example, in connection with the flashlight 300 described below. The possibility of a grounding path, without having to cut the skin to remove the anodic oxide or to mask the contact area before the anodizing process (previously in the case of a flashlight, 145907.doc • 30· 201038127).

The inner tail cap section 164 preferably includes threads 165 on the outer surface of the front portion of the inner tail cap section i 6 4 for mating with threads 131 on the inner surface of the rear portion of the barrel 124. The outer diameter of the inner end cap portion 164 and the outer end cap portion 1 70 are preferably sized so that the outer tail cap can be permanently pressed

The assembly is fitted to the rear end 2〇1 of the inner tail cap section 164, thereby forming an integral switch and a tail cap assembly 1〇6. The inner tail cap section 164 preferably comprises a conductive material such as aluminum.

A one-way (four), such as lip seal 162, may be provided at the interface between the barrel 124 and the switch and tail cap assembly H) 6 to provide a watertight seal while permitting overpressure in the flashlight (10) to be vented to atmosphere. However, other forms of sealing elements such as a ring-shaped ring may be used instead of the single-lut 162 to form a seal. Lip seal 162 preferably comprises a non-conductive material such as rubber.其他 Other configurations of switch and tail cap assembly 1〇6 can be used. For example, the switch function can be included in the side button switch or the internal rotary head switch _, such as in the US Patent Application No. 12 of 2 〇〇 Q: fci n 1/f, 1 January 14, 曰Used in /353,396. 8' Referring now to Figures 5A, 6 and 7, I, n·n〇 μ, the rechargeable battery cartridge 130 will now be further described. In general, the battery pack 13 U preferably includes a rechargeable battery; a circuit board that contains electronic devices such as recharge + 2 charging circuits and/or circuits for other functions, and contacts, 1 field, ' 'It is used to electrically connect the battery pack 130 to the remainder of the Feng Lei tube 100 or other lighting device. Thus, the battery pack 130 can represent a self-contained unit, which can be inserted into the battery compartment 127 of the barrel 124, together with the other components shown in Figure 5A, on the body 145907.doc -36 - 201038127. It is also preferred that the battery pack 13 provides protection for the electronic device and other components therein. As shown in Figure 6, the battery pack 13 includes a front end or lamp end cap assembly 210, a battery housing 230, an assembled circuit board 24A, a battery 26A, and a rear or tail cap assembly 270.

When assembled, the outer ring top contact 212 is located on the outer or front side of the front end cap 21, and the contacts 2! 4, 216 and the battery pack spring 218 are located on the inner or rear side of the front end (four). The front end cap assembly 21 is preferably manufactured in a manner that reduces the number of steps required to assemble the assembly. . Therefore, the front end cap 211 can be formed by plastic or other suitable material by injection molding. The injection molding process preferably includes - or a plurality of contacts 212, 214, 216 in common with the end cap 2, i.e., the contacts 212, 214, 216 can be positioned in the injection molding machine such that they are The injected material is surrounded by the injected material or otherwise held in place relative to each other as it solidifies. Because &amp;, the contacts are preferably located in the injection molding machine such that they end in position to form the end cap assembly 210 and the associated portion of the electrical path, as described later. The contacts (1), 214, 216 may also include circuit board clips that are similar to the circuit board clips of the contacts included in the front end caps. Although the co-molding process described above is better than 145907.doc -37- 201038127, the front end cap 211 and the contacts 212, 214, 216 can be assembled by other suitable means. Thereafter, the spring 21 8 is press-fitted between a plurality of retaining walls provided on the rear side of the front end cap 211, like the retaining wall 271 on the rear end cap 279 shown in Fig. 6. After assembling the front end cap assembly 210, it can be press fit into the front end or the lamp end of the outer casing 230. Preferably, the end cap 211 and the outer casing 230 are provided with cooperating members to lock the end cap 211 to the outer casing 230. Such components may include, for example, opposing projections 290 and apertures 29 1 . Other embodiments may employ other suitable means. The rear or end cap assembly 270 of this embodiment includes a battery pack spring 272, a bottom negative contact 274, an inner ring contact 276, a bottom outer ring contact 278, and a rear end cap 279. Each contact 274, 276, 278 can include a circuit board clip as shown by clips 274a, 276a, 278a. When assembled, the battery pack spring 272 and the bottom negative contact 274 can be located on the front or inner side of the end cap 279, while the inner ring contact 276 and the bottom outer ring contact 278 can be located on the rear or outer side of the end cap 279. . One or more of the rear end cap 279 and the contacts 274, 276, 278 can be co-molded as described above such that the contacts are properly positioned relative to one another to form the end cap assembly 270 and later Describe the relevant part of the electrical path. Alternatively, contacts 274, 276, 278 can be assembled by other suitable means. Thereafter, the spring 272 can be press fitted between the plurality of retaining walls 271 disposed on the front side of the rear end cap 279. When the rear end cap assembly 270 is assembled, it can be press fit into the rear or rear end of the outer casing 230. Preferably, the rear end cap 279 and the outer casing 230 are provided with phase 145907.doc -38 - 201038127 inter-engaging components (such as opposing protrusions 290 and holes 291) to lock the rear end cap 279 to the outer casing 23 This may occur via a protrusion on the back end housing 27 that corresponds to a hole in the peripheral 230 or by other suitable means. The base cap 211 and the trailing cap 279 can also include electrical contact guides on the inside of each of the end caps 211, 279. Figure 6 shows the guides 281, 282, 283 on the inside of the rear end cap 279. Although not shown in Fig. 6, the front end cap 211 may include guides 281, 282, 283 on its inner surface. As discussed later, these guides provide structural support and help locate the circuit board tabs 212a, 214a, 216a, 274a, 276a, and 278a of the electrical contacts 212, 214, 216, 274, 276, 278 to cause the clips The assembled circuit board 240 is properly engaged. The guides 281, 282, 283 may be formed adjacent the end caps 211, 279 during the injection molding process, or may be attached to the end caps by other suitable means. The battery casing 230 preferably has an outer diameter for fitting into the inner diameter of the barrel of the flashlight. Although the battery housing 23 and the battery pack 13 depicted in the figures are cylindrical in shape to accommodate the barrel 124 of the flashlight, the battery pack 130 can be configured in other shapes to accommodate different types of lighting fixture housings (eg, squares) Or rectangular lanterns). As shown in FIG. 6, the outer casing 230 preferably includes a wall 23 of a suitable thickness extending around its circumference or periphery. The thickness of the wall 23 is preferably sufficient to provide structural integrity to the overall battery pack 130 and thereby protect the electronic device and Other inclusions contained therein. Similarly, outer casing 230 is preferably constructed of plastic or other sufficiently strong material that provides this protection. Wall 231 preferably includes a recess 232 that extends axially 145907.doc • 39-201038127 along the length of outer casing 23〇. The recess 232 can include a recess or recess 233 that can also extend axially along the length of the outer casing 23〇. Recess 232 and recess 233 are preferably configured to receive assembly circuit board 240, such as by sliding assembly. Since the assembled circuit board 240 is contained within the outer casing 230, the battery 26 is eccentrically positioned in this embodiment to save space. This variation of the thickness of the wall 231 by the outer casing 23 is shown in Fig. 6. As shown, the thickness of the wall 231 increases near the location where the assembled circuit board 240 is positioned. The extra thickness allows the recess 232 and the recess 233 to be formed in the wall 231. This extra thickness also allows the inner surface of the wall 231 to be cylindrical to correspond to the outer surface of the battery 260 and to achieve a snug fit. And as shown, the outer surface of the outer casing 230 is also cylindrical to correspond to the inner diameter of the barrel 124 of the flashlight. As indicated above, in other embodiments, the battery pack 丨3 〇 can be formed in a non-cylindrical configuration to accommodate non-cylindrical lighting devices. If so, the outer casing 230 and its wall 23 1 can be configured differently to accommodate the shape of the battery circuit board 24 and such alternative lighting devices. The active area of the assembled circuit board 240 (i.e., the portion of the assembled circuit board 240 that generally includes the electronic device) preferably does not extend to the board edge region 241. When the assembled circuit board 240 is assembled within the outer casing 230, the edge region 241 is preferably fitted within the recess 233' thereby securing the assembled circuit board 240 within the outer casing 230. The assembled circuit board 240 includes front electrical contacts 242a, 242b, 242c and rear electrical contacts 244a, 244b, 244c. When the battery pack 130 is assembled, the electrical contacts are electrically coupled to the circuit board clips included on each of the front end cap assembly 210 and the rear end cap assembly 270 to form a battery pack 13 One part of the conductive path. More specifically, the following board clip/circuit pad connections form 145907.doc -40- 201038127 in the battery pack 230 of the present embodiment: 212a/242a, 216a/242b, 214a/242c and 276a/244a, 274a/ 244b and 278a/244c. As shown in Figure 6, the 'parent-board clip contains a fork that grips the assembled circuit board 240. Guides 281, 282, 283 (and similar guides on the inside of the front cap guide on the inside of the front cap 211) can help position and support the tabs to ensure that such electrical connections are made and not damaged Board clips.

The conductive path of the battery pack 13 is described with reference to Figs. 6 and 7. As shown, the rechargeable battery 260 includes a positive terminal 262 and a negative terminal 264. The positive terminal 262 is coupled to the assembled circuit board 240 via a battery pack spring 218, a top positive contact 216, and a circuit board clip 216a formed as part of the top positive contact 216. The board clip 2 16a is preferably coupled to the contact pads 242b on the assembled circuit board 24A. (It should be noted that in FIG. 7, the reference numerals do not show physical components and are instead used to schematically indicate the electrical connections provided thereby.) This positive path continues on circuit board 240 to contact pads 242c, which are coupled The circuit board clip 2 14a formed as part of the universal top positive contact 2 14 extends through the contact 214 to the top central positive contact 214b, which in this embodiment is the top central positive contact 21 It is a protrusion (] 〇 11113) that can be formed as part of the contact 214. The protrusion 2141 is preferably extended to the outside of the battery '' and 130 and forms a positive electrode that contacts the compressible positive contact η] of the lamp module 128. The heat sink housing 188, which is shown in FIG. 7 as the dotted light module 128, is then grounded to the battery pack 130 via the shoulder ring 126, which in turn is the top of the negative electrode that forms the battery pack 13〇. Contact 212 is in contact. This connection is indicated by the dotted line 21 in Fig. 7. The board clip 212a is then coupled to contact pads 145907.doc-41 - 201038127 242a on the assembled circuit board 24. The negative terminal 264 of the battery 260 can be electrically coupled to the assembled circuit board 240 via a battery pack spring 272, a bottom negative contact 274, and a circuit board clip 27 that is formed as part of the contact 274. The board loss piece 274a preferably extends through the guide member 282 and engages the contact pad 244b on the assembled circuit board 240.

In addition, the protrusion 274b of the bottom negative contact 274 extends to the outside of the battery pack 13 and forms a negative electrode or protrusion for external contact with the ground contact pad on the circuit board via the contact pin 136 and the pin spring 142. 27 servants. This connection is represented in Figure 7 by the dotted line shown as 289b. The electrical path of the switch can also be extended from the self-assembled circuit board 240 for momentary opening to the switch and tail cap assembly 106. The electrical contact pads (10) on the assembled circuit board 24 are surface-contacted to the circuit board core, which is formed as a portion of the bottom outer ring contact 278 and extends through the guide. Outer ring contact 278 forms an external positive charging contact for battery pack 13G. It passes through the contact pad (4) and the pin spring 146 (4) to the +5 VDC contact pad on the circuit board 148 contained in the switch and tail cap assembly (10). This circuit path is shown in Figure 7

The dotted line is 2 8 9 a. The other electrical path is as follows: and the circuit board 240 is extended. Assemble the circuit board: The upper electrical contact 塾 244a is lightly connected to the hard &amp; ^ m to ^ becomes part of the inner ring contact 276 % of the plate clamp 276a. On the inner ring shrinkage, the contact can be taken from the contact pin 138 via the contact pin 138 to the switch board 148 which is included in the switch cover and the tail cap assembly 106. The MOM circuit is responsible for the board. This electrical path connects the momentary switch to the current description of the circuit of the flashlight 100 and its supply. Flashlight 145907.doc -42· 201038127 The circuit of the cartridge 100 includes a main power circuit for powering the light source 101, a controller circuit for powering the controller and other electronic devices on the assembled circuit board 240, and for Rechargeable battery 26 〇 recharge charging circuit. The main power supply circuit for the light source passes from the positive electrode 262 through the spring 218, the top positive contact 216, the circuit board clip 216a, the contact pad 242b, the assembled printed circuit board 240, the contact pad 242c, the circuit board clip 214a, and the universal positive Contact 214 extends to the LED or other source of light via the circuit path indicated by dotted line 2 15a described above. The LED or other light source is then grounded to the battery pack 130 via a circuit path formed by dotted line 215b as described above via a negative electrode formed by outer ring top contact 212. The circuit then extends through the board clip 2i2a, the contact pad 242a assembly printed circuit board 240, the contact pad 244b, the board panel 274a, the bottom negative contact 274, and the spring 272 to the negative terminal 264 of the rechargeable battery 260. This circuit differs from the circuits found in some existing flashlights in that it is typically self-contained in the battery pack. By way of example, some existing flashlights use the cartridge as part of a ground connection in a circuit for powering a light source. However, the main power supply circuit of the present embodiment does not rely on an electrical path including a barrel, a head or a tail cap as part of a main power supply circuit for supplying power to the light source 101. This is advantageous because in the case where the barrel is used to complete the circuit, the manufacturing steps that typically require removal or processing of the barrel surface to provide a good conductive path are required. However, the self-contained nature of the power supply circuit of the present invention avoids any such steps, which can reduce manufacturing costs and complexity. The circuitry for powering the controller that assembles the circuit board 24 can extend from the positive electrode 262 through the spring 218, the top positive contact 216, the board slab plus I45907.doc -43-201038127, and the assembled circuit board 240.塾2421), which can be used to guide the circuit when necessary. The ground path to the negative electrode of battery 26 includes contact 244b to negative electrode 264, circuit board clip 274 &amp; bottom negative contact 274 and magazine 272. This circuit is also advantageous in that the circuitry required to power the assembled circuit board 240 is fully provided within the battery pack 13 and does not require external circuit paths that add additional cost and manufacturing complexity. The high voltage side of the circuit for recharging the battery 260 extends from the positive charging ring 19A to the coil springs 156, 158, the printed circuit board 148, the pin springs 146, the contact pins 140, via the bottom outer ring contacts 278 to the battery The set of 13 turns and then passes through the board clamp 278a, the contact pads 244c, the assembled circuit board 24, the contact pads 242b, the board clip 216a, the top positive contact 216, the spring 218, and finally to the positive terminal 262 of the battery 260. . The circuit can then be returned from the negative terminal 264 of the battery 26 to the spring 272, the bottom negative contact 274, via the tab 27 to the contact pin 136, the pin spring 142, the circuit board, the wave springs 15A, 158, ground charging Ring 192. When the battery pack 130 is mounted into the battery compartment 127 of the barrel 124, the complete electrical path (or electrical load) for the light source 101 can be from the positive terminal of the rechargeable battery 260 via the input pad 242b of the assembled circuit board 24 Formed as described above. The input pad 242b corresponding to V-CELL+ in Fig. 7 is coupled to the load switches 558, 572 on the assembled circuit board 240 (see Figures 9b, 9C). When the load switches 558, 572 are closed (or conductive), the output pads 242c on the assembled circuit board 240 are energized. Because the output pad 242c is coupled to the top center positive contact 214b of the battery pack 130, current is transferred from the top center positive contact 214b of the battery pack 130 to the positive contact 133 of the lamp module 128 and through the source. This electrical path 145907.doc -44 - 201038127 then extends from the heat sink housing 188 of the lamp module 128 to the outer top contact 212 of the battery pack 130. The outer ring top contact 212 of the battery pack 130 is electrically coupled to the negative electrode 264 of the rechargeable battery 260, as described above. Figure 8 is a block diagram showing the relationship of an electronic circuit of a preferred embodiment of an assembled circuit board 240 for a portable lighting device such as the flashlight illustrated and discussed in connection with Figures 1-7. However, the circuit and motion sensitive user interface provided thereby can be used in flashlights other than flashlight 100 and other portable lighting devices such as headlights or lanterns. The assembled circuit board 240 preferably includes a charging system 502, a battery protection circuit 504, a MOSFET driver and load switch circuit 506, an LDO linear regulator circuit 508, a controller circuit 510, an accelerometer circuit 512, and a magnetometer circuit 514. In other embodiments, one or more of these components may be omitted when their functionality is not desired in a particular application of the invention. As indicated above, assembled circuit board 240 includes electrical contacts, preferably in the form of I/O pads. As reflected in the detailed circuit diagram of the assembled circuit board 240 shown in FIGS. 9A through 9G, the I/O pads may include +5 VDC 244c, MOM 244a, bottom GND 244b, V_CELL + 242b, VLOAD 242c, and top GND 242a. . FIG. 9A shows a circuit schematic of charging system 502. The +5 VDC signal line 516 can be electrically coupled to the +5 VDC input pad 244c on the assembled circuit board 240 of the battery pack 130. As mentioned previously, the +5 VDC input pad 244c can be electrically coupled to the charging ring 166. The +5 VDC signal line 516 is coupled to a p-channel metal oxide semiconductor field effect transistor (PMOS) 530. The gate of PMOS 530 can be coupled to ground such that PMOS 530 can be turned on when 145907.doc -45 - 201038127 + 5VDC I/O pad 516 is coupled to a positive supply voltage such as a charging base. If the +5 VDC I/O pad 510 is accidentally coupled to a negative supply voltage (such as in the case where the flashlight _ 1 〇〇 is placed upside down on the charging base), the PM 〇s 530 will be turned off to protect the assembled circuit. The remainder of the circuit on board 24 is protected from reverse polarity damage. The source 532 of the PMOS 530 can be coupled to the charge protection circuit 536 to provide protection to the battery 260 in the battery pack 130 from failure due to the charging circuit 544, which will be discussed in more detail later. description. The k-line 532 can be coupled to the collector of the bipolar transistor 534, and the base of the bipolar transistor 534 can be coupled to the signal line 丨WIRE 63〇, which is again the controller circuit 51〇 The output. The charge protection circuit 536 can include an output v_wall_adAPTER 538 that can be coupled to the charging circuit 544. The charge protection circuit 536 can be used to continuously monitor the input voltage +5Vdc 516, the input current, and the battery voltage 54〇. The charge protection circuit 536 can be moved from the charging circuit 536 by turning off the internal switch in the charge protection circuit 536 under conditions in which an excessive input voltage can be experienced (eg, the flashlight 100 is placed on a charging base that provides a +12V DC input). In addition to electricity. In the event of an excessive current condition, the charge protection circuit 536 can limit the system current to a threshold. The current flow condition in the right over is continued. Then the charge protection circuit 536 can cut off the transfer element after the blanking period. In the preferred embodiment, a commercially available device (e.g., BQ243 14 manufactured by Texas) can be used to protect against battery voltage and current and protect the battery charger at the extreme end. 145907.doc 201038127 Charging circuit 544 can be powered by V_WALL_ADAPTER 538 and can be used to charge rechargeable battery 260 located within battery pack 130. In charging system 502, charging circuit 544 can include a current sensitive circuit and a thermal conditioning circuit to limit the charging current. The charging circuit 544 can have an output VCHARGE 538 that can ultimately be coupled to the positive electrode of the rechargeable battery 260. In the preferred embodiment, a commercially available stand-alone charge manager controller (e.g., MCP73832 manufactured by Microchip Technology) can be used. Signal line DISABLE_CHARGE 624 from controller circuit 510 can be used to disable charging circuit 544. In this case, V_WALL_ADAPTER 538 displays a high impedance so that the flashlight 1 is in communication with the external charging base via signal lines 1_^\¥11^ 63 0 and +5¥〇. Signal line CHG 63 0 can be used to indicate the state of charge, which can be used by controller circuit 510. While an overpower condition is detected, although the charge protection circuit 536 can be used to protect components on the assembled circuit board 240 from other damage, it would be advantageous to transmit this information to the charging dock. In this embodiment, when an overpower condition is detected, the controller 602 can utilize the signal line 1_WIRE 630 to send a sequence signal to the charging base as a warning sign. Signal line 1_WIRE 630 can be pulled high by controller 602 such that the collector of NPN bipolar transistor 534 can be pulled low. Therefore, signal line 530 and +5 VDC 5 16 can be pulled low. Therefore, from the flashlight point of view, +5 VDC 5 16 can be converted from the power input line to the signal output line. When the high signal on +5 VDC is desired, signal line 1_WIRE 630 can be pulled low by controller 602 such that the collector of NPN bipolar transistor 534 and signal line 53 0 will no longer be pulled low. Thus, controller 602 can process 145907.doc -47 - 201038127 + 5VDC 616 as a serial port for transmitting a sequence of high or low signals. The battery voltage can also be monitored by charge protection circuit 536 at signal line 540, which is fed back from VCHARGE 548. A charging system other than the above charging system 502 can also be used. FIG. 9B shows a circuit schematic of battery protection circuit 504. Battery protection circuit 504 can include an input VCHARGE 548 that extends from charging system 502 in this embodiment. The input signal line VCHARGE 548 is coupled to the source of the PMOS 55〇. The PMOS 55 闸 gate is coupled to the input signal line VCHARGE 548 via a resistor. And the gate of the 'PMOS 550 can be driven by the internal signal line CO 564 via the inverter 5 68. The PMOS 550 has a pole connected to the signal line V_CELL+522, which can be further coupled to the I/O 塾 V_CELL+242b on the assembled circuit board 24. As described above, '1/〇 塾 v cELL + 242b is consumed to the positive electrode of the rechargeable battery 260 in the battery pack 130. The signal line V_CELL+522 can also be driven by the signal line VCHARGE 548 via the diode 554. The k-line V-CELL+522 is drained to the input of the load switch 558, and the output of the load switch 558 is lightly connected to the internal supply voltage signal vb AT 5 6 0, which is in turn via the signal line VLOAD 524 (shown in Figure 9C). And the 1/〇 pad VLOAD 242c is connected to the positive contact 133 of the lamp module 128. When a short circuit is detected on the load (e.g., lamp module 128), load switch 558 will be turned off to protect the circuit. In the preferred embodiment, a commercially available load switch can be used (e.g., by

FPF2163 manufactured by Fairchild Semiconductor). Voltage protection circuit 562 can be used to further protect rechargeable battery 260 in battery pack 13 from overcharging, overdischarging, or excessive current. In an embodiment 145907.doc • 48· 201038127, a commercially available voltage protection circuit (for example, S-8241ABSPG manufactured by Seiko Instruments) can be used. A battery protection circuit other than the battery protection circuit 504 described above may also be employed. Figure 9C shows a circuit diagram of a preferred MOSFET driver and load switch circuit 506. In the embodiment of FIG. 9C, the load switch circuit 506 is implemented by a PMOS 572 having a source coupled to the internal supply voltage signal VBAT 560 from the battery protection circuit 504 and coupled to the signal line 乂: 0 8 0 5 76 bungee jumping. The signal line ¥]^0 八 0 524 is coupled to the I/O pad VLOAD 242c of the assembled circuit board 240. As previously described, the I/O pad VLOAD 242c is coupled to the top center contact 214b of the battery pack 130 and can then be coupled to the compressible positive contact 133 of the lamp module 128. The gate of PMOS 572 can be coupled to a MOSFET driver that can be implemented by an NPN bipolar transistor 570. The gate of PMOS 572 can also be pulled high by the resistor until the internal supply voltage signal VBAT 560. Thus, when the base of bipolar transistor 570 is driven high by signal LAMP_DRIVE 624, bipolar transistor 570 conducts like PMOS 572. Thus, power can flow from the internal supply voltage VBAT 560 to the voltage output pad VLOAD 242c to form a portion of the complete loop that can turn the current to the lamp module 128. In other embodiments, controller 510 can directly drive load switch 572. In addition, other forms of driver circuits can be employed. Likewise, other types of load switches can be used for load switch 506. In general, the load switch 506 should be an electronic switch such as a field effect transistor or a bipolar junction transistor 145907.doc -49- 201038127. Figure 9D shows a circuit diagram of a preferred low dropout (or L D 〇) linear regulator circuit 5 〇 8. The LDO linear regulator circuit 5A8 can include a low dropout regulator 588 that can be implemented with a small input-output differential voltage (: linear voltage regulator implemented. Signal line 586 forms an output from two diodes 582, 584 It is driven by the L-line V_WALL_ADAPTER 53 8 and VBAT 5 60. This configuration preferably allows a higher voltage supply from the signal lines V-WALL__ADAPTER 538 and VBAT 560 to supply the low-dropout regulator 588. In a preferred embodiment The output of the low dropout regulator 588 can be set to +2.8 V on output line 590 for use as a power source for, for example, controller circuit 5, accelerometer 5 j 2 , and other components of magnetometer 5 14. In the example, a commercially available LDO regulator can be used (e.g., 'NCP 700 manufactured by On Semiconductor.) A linear regulator circuit other than the linear regulator circuit 508 described above can also be used. Figure 9E is a schematic diagram of a preferred controller circuit 510. The controller circuit 51A can include a controller 602 having input and output connections. The controller 602 can be via signal lines ADC-DC XOUT 608, ADC_DC_YOUT 606, ADC DC ZOUT 604, ADC XG 612, ADC YG 614, A The DC_Z-G616, CHG 628, and RESET 634 receive input signals. The controller 602 can also be via signal lines PD 610, ST 618, SW_ON 630, S/R/MOSI 620, LAMP_DRIVE_MISO 622, DISABLE-COMPASS 624 'CHARGE_DISABLE 626, and 1_WIRE 630. The output signal is transmitted. The power supply VCC (not shown) of the controller 602 is powered by +2.8V 145907.doc -50· 201038127. The +2.8V power signal is rotated by the LD〇 regulator 5〇8. In the example, the batch controller 602 is a commercially available microcontroller with embedded memory, for example, ^ y 1 ' which is an 8-bit microcontroller manufactured by Atmel Corporation &amp; The controller 602 can be a microprocessor. In other embodiments, the controller 6() 2 can be a discrete circuit. It should be understood by those skilled in the art that it can also be used. Other types of controller circuits0

Figure 9F shows a circuit diagram of a less preferred exemplary accelerometer circuit 52. The accelerating D ten circuit 5 12 is preferably a 3-axis accelerometer. However, in other embodiments, a single or dual axis accelerometer can be used. The accelerometer circuit of the preferred embodiment includes an output ADC-X-G 616, ADC-Y-G 612 corresponding to signals representing movements in each of the X, yAz directions. These three signals are coupled to the controller circuit 51 for further processing.

Source signal support line 590 is provided. Accelerometer circuit 5 12 preferably includes an inertial sensor 64A that receives information from the internal sensing element and provides an analog signal. In other embodiments, inertial sensor 640 can convert the analog signal it produces into a digital signal. Inertial sensor 640 is used in this embodiment to measure the earth's static gravitational field by providing acceleration information on three axes (eg, X, 丫, and illusion) of mutually orthogonal axes. 3-axis accelerometer The power supply VDD of circuit 512 can be supported by a +2.8 V power supply signal from output line 590 of LDO regulator 508. If the Z-axis of inertial sensor 640 points to the center of the earth, then X and γ will have an acceleration of zero. Because the Earth's gravity Z will experience an acceleration of _ 1 g. If the inertial sensor 640 flips 180. So that z is facing away from the Earth, then X and 145907.doc •51 · 201038127 Y will remain at zero, but Z will have Acceleration of +ig. Inertial sensor 640 is attached to assembled circuit board 240 such that the X, 丫, and z axes are fixed relative to flashlight 100. In the preferred embodiment, inertial sensor 64 is oriented on plate 240 The gamma axis extends along the longitudinal axis of the flashlight 1 。. Thus, the horizontally-rich chirped flashlight extends horizontally with the 'y-axis' at 100. In this position, when X and Z are rotated left or right around the longitudinal axis of the flashlight 100 When the magnitude of the acceleration on the X and z axes changes during rotation The corresponding gravitational information about X and z will be sent to controller 602 via ADCX-G 616 and ADC_Z-G 612, respectively. The relative angular rotation can therefore be calculated by controller 602. Controller 602 can use ADC-XG 616 and ADC_Z-G 012 The above information is used to determine if there is a rotation and direction of rotation about the longitudinal axis of the flashlight 100. In the preferred embodiment, the switch for the flashlight 1 is located in the switch and tail cap assembly 106. When the switch is initially activated The initial orientation of the z-axis is unknown to the controller 602. Thus, the controller 6〇2 calculates the starting angle or position based on the measurement of the Earth's gravitational field on the X and Z axes in the starting orientation. Establishing its initial orientation, subsequent angular measurements can be taken to track the rotation of the flashlight 100. Thus, measurements can be made to determine whether the angle is increased or decreased relative to the starting orientation to calculate the rotational change. In another embodiment, Knowing the two axes of the portable lighting device. For example, in a flashlight with a push button switch, the starting position with the z-axis will be known, assuming that: as specified by the shape of the user's hand, switch Up, where the thumb is on the switch. In this case, only one axis (X or Z) can be used to calculate the change in rotation, and therefore a single-axis accelerometer can be used. 145907.doc -52. 201038127 In the above two implementations In the example, it is preferred that the flashlight ι is positioned substantially horizontally for the user to obtain a higher resolution when rotating (i.e., better sensing of the rotation of the shaft). When the Υ axis is tilted relative to the horizontal direction At a distance, a rotation error can occur. Therefore, in operation +, it is preferable that the flashlight is held to +Λ 30 with respect to the horizontal direction. . If the tilt is greater than 3 inches. Preferably, the axle is monitored and the rotary input is ignored until the flashlight (10) is tilted back to +/- 30. Up to the window. However, in other embodiments, a more complex

The hash vector is calculated such that the 3 axes are combined such that the user's intention can be determined regardless of the level. The f-beat detector 640 can include an input pd 610, which can be an output from the controller circuit 510. The PD 610 can be used as an indication that the inertial sensor 640 does not need to be operated by pulling the *pD 610 low. When the pD 61〇 is pulled low, the inertial sensor 640 can remain in the power down condition. This configuration can be used to conserve battery power. The inertial sensor 640 can also include an input ST 618 ' which can be an output from the controller circuit 510 to indicate that the self test is desired. In a preferred embodiment, the inertial sensor 640 can be a commercially available microelectromechanical system (MEMS), such as the LIS 394AL, which is a 3-axis accelerometer manufactured by ST Microelectronics. Those skilled in the art will appreciate that other types of inertial sensor circuits can be used. Figure 9G shows a schematic diagram of a magnetoresistive sensor circuit 514. Magnetoresistive sensor circuit 514 can include inputs COMPASS_DISABLE 624 and S/R/MOSI 620, which can be outputs from controller circuit 52. The exemplary magnetoresistive sensor circuit 514 can also include an output 八 (: __0 (: _ _ 01; D 608, 145907. doc • 53 - 201038127 ADC_DC_YOUT 606 and ADC_DC_ZOUT 604, which can be coupled to the controller circuit 512 For further processing. When the input signal C〇MPASS_DISABLE 624 is driven low, the +2.8V power supply can be used to support the magnetoresistive sensor circuit 514. When the controller 602 determines that the magnetoresistive sensor circuit 514 does not need to operate At this time, the input signal COMPASS_DISABLE 624 can be pulled high by the controller 602. The +2.8V power supply can then stop supporting the magnetoresistive sensor circuit 514. This configuration can be used to conserve battery power. The main components of the magnetoresistive sensor circuit 514 are Magnetometer 660. Magnetometer 660 can include three sets of Wheatstone bridges placed at orthogonal axes to measure the direction and magnitude of the Earth's magnetic field on each of the equiaxed axes and These measurements are converted to a differential voltage output. In other embodiments, a single or dual axis magnetometer can be used. In the preferred embodiment, the Y axis is set to the longitudinal axis 110 of the flashlight 100. In other words, Will output ADC_DC_YOUT 606 The change is explained by the change in the direction of the longitudinal axis 110 of the flashlight 100. The magnetometer 660 can be a commercially available magnetometer, such as the HMC 1043, which is a 3-axis magnetometer manufactured by Honeywell.

The power supply of the Wheatstone bridge in the magnetometer 660 (indicated by VB) can be supported by the signal line +VCOMPASS 644, which in turn can be generated from the +2 provided on the output 590 of the LDO regulator 508. 8V power signal. The emitter of the PNP bipolar transistor 642 is coupled to +2. The 8V 590 power supply, and the collector of the bipolar transistor 642 is coupled to the signal line +VCOMPASS 644. The base of the bipolar transistor 642 can be coupled to the signal line COMPASS DISABLE 145907. Doc-54-201038127 624, which may be a round trip from controller circuit 512. The set/reset (SR) input of magnetometer 660 can be provided from two sources. The first source can be the signal line +VCOMPASS 644. The second source can be generated from signal line S/R/MOSI 620, which can be an output from controller circuit 510. The signal line S/R/MOSI 620 can be coupled to the base of the NPN bipolar transistor 654 whose emitter is coupled to ground. The signal line 652, which can be coupled to the collector of the bipolar transistor 654, can also be the second source of the set/reset (SR) input of the magnetometer 660. The output of magnetometer 660 can be grouped into three sets of differential voltage outputs: OUTX+662 and OUTX-664; OUTY+666 and OUTY-668; and OUTY+670 and OUTY-672. OUTX+662, OUTX-664 can be coupled to the positive and negative inputs of operational amplifier 682, respectively, which can produce an output ADC_DC_XOUT 608 that can be coupled to controller circuit 510 for further processing. Output 八(:_0(:_乂01; butyl 608 can be fed back to the negative input 678 of operational amplifier 682 via resistor 686 and capacitor 688 connected in parallel. Additionally, the positive input of operational amplifier 680 can be coupled to the reference voltage REF_COMPASS It can be generated by a voltage divider from +VCOMPASS 644. Likewise, other sets of differential voltage outputs can be used to generate ADC_DC_YOUT 606 and ADC_DC_ZOUT 604, which can also have a configuration similar to the configuration of ADC_DC_XOUT 608 previously described. In the above embodiment, the flashlight 1 is operable as an electronic compass. In this mode of operation, a visual, audible or tactile response may be provided depending on which direction the flashlight 100 is directed to. For example, the flashlight 100 Light module 145907. The illumination intensity (or brightness) of doc -55- 201038127 128 may vary depending on the direction in which the flashlight 100 is pointing. In an embodiment, when the flashlight 100 is pointed to magnetic north, the illumination intensity may be brighter (e.g., at maximum brightness). When the user rotates the flashlight (10) clockwise or counterclockwise toward the magnetic south, the illumination intensity can be reduced and can be set to a lower position*, for example, when pointing to the south, the minimum brightness. In an alternate embodiment, the brightness level can be reversed. Preferably, flashlight 100 remains substantially horizontal, i.e., the rotation of flashlight 100 occurs about an axis substantially perpendicular to the ground. In this manner, the flashlight 1 can be used as a compass, and the user can determine the north-north direction, the south-right direction, and the direction therebetween based on the varying intensity of the lamp module 128. In addition to varying brightness, the light module 128 can be flashed to provide other directions to the user when the flashlight 1 is pointing to or near the north, south, east, and west. For example, the flicker can be programmed to occur when the flashlight 1 〇〇 points in a direction relative to an angle (eg, +/_ 5) relative to north, south, east, or west. 3 In addition to the visual response discussed above, flashlight 100 can be configured to provide an audible or tactile response in addition to or in lieu of a visual response. For example, the programmable controller 510 can rotate a sequence of beeps or provide different tones depending on the direction in which the flashlight is directed. In addition, when the flashlight points in the direction of "North", "South", "East" and "West": the flashlight can sound "North", "South", "East" or "West". This = audible response will be via the audio interface and speaker 518 (see figure, the audio interface and speaker 518 are in communication with the controller 510. Alternatively, the controller 510 can be connected to the vibrator instead of the audio interface and the speaker 145907. The doc 201038127 518 provides a tactile response that varies depending on the direction in which the flashlight is pointed. The vibrator can be, for example, an eccentric hammer. As noted above, it is preferred that the user maintains the flashlight = 〇 at a substantially water position while using the flashlight 100 as a magnetic compass. If this is not the case, the flashlight is just being operated, and an error can occur in the compass operation. Preferably, this error is corrected by the accelerometer circuit 512 described in conjunction with the figure, the Y-axis measuring the tilt angle of the flashlight and then using this information to correct the operation of the ram. Those skilled in the art will appreciate that other types of magnetoresistive sensor circuits can be employed. As indicated above, it is preferred that the flashlight can operate in a variety of modes. :: Step-by-step discussion of the operation and access of these modes. Fig. 1 is a flow chart showing the preferred operation mode 7〇2 of the flashlight with 100 being accessible and executing various modes. The user can initially press and release the sequence to activate the switch 168 of the flashlight (10), as in step S704. The flashlight 100 is thus turned "on" in step 706 and can begin to produce light and can enter the first mode of operation or mode of operation! As in step 7咐. In the preferred embodiment, the first mode of operation may be a normal or standard mode of operation in which the light module 128 provides a steady beam of light. At this stage, if the controller executes another - (4) and releases the sequence _ 168, the flashlight 1 can recognize the sequence as the shutdown command 71 and can turn off the flashlight 100, as in step 712. If there is no shutdown command, the user can enter the second mode of operation 718. This can be accomplished by rotating the flashlight 714 about the throwing spindle U0 about its throwing spindle U0 while keeping the switch 168 continuously depressed 716. 145907. Doc •57- 201038127 “While the flashlight 1GG is in the first operation mode (no interruption 7ι〇), the right does not measure the rotation of the main axis 11〇 to the right 7i4 or if it is detected around it. Rotating 714 to the right but the switch 168 is not continuously depressed 716, the flashlight 100 remains in the first mode of operation 7 〇 8. Once the flashlight 100 is in the second mode of operation 718, it can be another button and release sequence Turning off 'as in step 720. If the flashlight 100 is not turned off but instead rotates 722 about its projection spindle 11 () to the right while the switch is continuously depressed 724, the flashlight (10) can enter the third mode of operation. In Figure iA, this is indicated by mode N 726. This means that the flashlight preferably follows the sequence described above to access any number of operating materials. However, in the preferred embodiment, there are five modes of operation. Field flashlight 100 is in the first In the second mode of operation, at 718 (unrelated to 720), if the rightward rotation 722 along its projection spindle 11 is not detected or if the rightward rotation 722 is detected about its projection spindle 110, the switch 168 is not continuously pressed. Under 724, the flashlight remains In the second mode of operation 718. When the flashlight 1 is in the last mode of operation 726, it can press and release the sequence off 728. When the flashlight 1 is in the last mode of operation (unrelated 728), if the flashlight 100 rotates to the right around its projection spindle 11"" While the switch 168 is continuously depressed 732, the flashlight 1 can be returned to the first mode of operation 708. When the flashlight 1 is in the last mode of operation 726 (no interruption 728), the right does not detect a rightward rotation of the projection axis 丨1〇 73〇 or if the right rotation of the projection spindle 110 is detected 73 While the switch 168 is not continuously depressed 732, the flashlight 100 remains in the last mode of operation 726. 145907. Doc-58- 201038127 Thus, in the preferred embodiment, flashlight 100 can be rotated to the right by rotating its main axis 110 while maintaining switch 168 continuously depressed for additional operational modes. This operation allows the flashlight 100 to enter the new mode of operation without the use of a sequence of presses and releases of the switch button. While there are various modes of operation that are within the scope of the present invention, in a preferred embodiment, stable illumination with variable brightness can be set to the first mode of operation 708. The blinking illumination with variable brightness can be set to the second operating mode 718. Other modes of operation may include a SOS mode with variable brightness, a motion sensitive signal mode, an electronic compass mode, and a night light mode. These modes of operation can be assigned in any order or as desired by the user. Therefore, if the user thinks that he or she frequently uses the mode(s) more than others, the user can set the first few modes. As previously described in connection with FIG. 9F, 3-axis accelerometer circuit 512 can include output ADC-X-G 616, ADC_Y-G 614, and ADC_Z-G 012, which can be coupled to controller circuit 510. The accelerometer circuit 512 can be mounted to the assembled electrical Q board 240 with its Y axis pointing along the longitudinal axis of the flashlight 1〇〇. Therefore, when the flashlight 100 is placed horizontally, if the flashlight 100 rotates clockwise or counterclockwise along the longitudinal axis of the flashlight 1 则, the magnitude of the acceleration on the z-axis will be changed, and the X and z may be Gravity information is sent to controller 602 via adc_x_g '616 and ADC-ZG 612, respectively. The controller 6〇2 can use the information on 八((:_乂-0 616 and 八0(:_2-0 612) to determine whether there is rotation along the longitudinal axis of the flashlight 100. Therefore, the flashlight can be wound around The rotation of its vertical axis (or information changes on ADC_X-G 616 and ADC-ZG 612) is used as a command decision point to determine whether to enter the new operating mode. Doc - 59 - 201038127 The operational flow 702 shown in Figure 10A can be implemented by software stored in the memory on the controller 6〇2. The programmable controller 6〇2 thus controls the sequence of operations based on signals received from the output of the 3-axis accelerometer circuit 512. In other words, when the controller 602 receives the beta hole from the ADC_X-G 616 and the ADC-Z-G 612, the controller 602 can change its execution sequence based on the information received from the output of the 3-axis accelerometer circuit 512. The controller 602 can also be programmed to control the flow of power through the lamp module 128 based on signals received from the output of the 3-axis accelerometer circuit 512. That is, when controller 602 receives information on ADC-X-G 616 and ADC-Z-G 612, controller 602 can change some of its output apostrophes based on the execution of the software stored in controller 〇2. For example, controller 6〇2 can pull its output #number LAMP_DRIVE 624 to a high state to cause bipolar transistor 570 and PMOS 5 72 to conduct. In this manner, power can flow from internal supply voltage VBAT 560 to voltage output pad VL 〇 AD 576 to form a portion of the loop that can be used to pass current to lamp module 128. Heat I should understand that the flowchart in Figure A is only an example, and other types of operations can be used. For example, when the flashlight 100 is rotated to its left about its projection spindle 110 while the switch 168 is depressed, a command for entering into the new mode of operation can be implemented. Alternatively, other types of movements of the flashlight (10) that can cause changes in the output of the 3-axis accelerometer circuit 512, ADc_x_g 616, ADC-YG 614, or ADC-ZG 612, can also be used for flashlights 1 to new operations. In mode. μ Referring now to Figure 101, the differences expected by the present invention are more specifically described. Doc •60· 201038127 Examples of operating modes and how each mode can be adjusted. Those skilled in the art will appreciate that modes of operation other than those described above are within the scope of the present invention. 1B is a flow diagram illustrating an electronic compass operation 740 that may be performed by flashlight 100. Flashlight 100 can perform a plurality of modes of operation as previously described in connection with FIG. 10A. Preferably, the flashlight 100 can be switched from one mode of operation to the other by rotating the flashlight 100 about its projection spindle 110 while the switch 168 is continuously depressed. When the flashlight 100 has entered the electronic compass mode 742, the light source of the flashlight 100 initially produces a steady standard optical flow. After the step of operation 740, the flashlight 100 can be turned off 712 by a specified method, for example, the user performs a shutdown command 744 such as pressing and releasing of the switch 168. When the flashlight 1 is in the electronic compass mode 742 (unrelated to 744), the right flashlight 100 rotates 746 to its right about its projection spindle 110 while the switch 168 is continuously depressed 748, the flashlight 1〇〇 can proceed to the next operation. Mode 75〇❹. The next mode of operation can be specified as any of the following examples: stable illumination with variable twist, flicker illumination with variable brightness, SOS mode with variable 7C degrees, motion sensitive signal mode, or night light mode . Alternatively, • The next mode 750 can be different from the modes listed above. The user can remain in the electronic compass mode 742 as follows. If the rightward rotation 746 around the projection spindle 11〇 is not detected or if the rightward rotation 746 around which the projection spindle 11〇 is detected but the switch 168 is not continuously depressed 748, the flashlight 1〇〇 remains Electronic compass mode 742. 145907. Doc - 61 - 201038127 In step 752, the compass mode provides a blinking capability to alert the user that the flashlight is pointing to or near any of the four basic magnetic coordinates (i.e., north, south, east, or west). To help describe this feature, it should be noted that flashlight 100 generally has a midpoint or center point along its longitudinal axis. And if the vertical axis extends through 1 point, the flashlight 1GG can be rotated by the user around the center. The flashlight 100 can have a center of rotation. Here, if the flashlight 100 is rotated about this center point or rotated about its center of rotation, such that its longitudinal axis points to 10 which falls into one of the basic magnetic coordinates. In the direction of the corner 752, the flashlight will be flashed. In other embodiments, the flash can be directed to the flashlight (10) on the side of the basic magnetic coordinate. Occurs within the direction. Therefore, the user is warned that it is generally oriented to the basic magnetic coordinates. The range of angles included in the overlay flashing can also be +/_ 5. Outside the angular range. Another feature within compass mode 742 can also be used with the present invention. When the flashlight 100 rotates around it, if the front end of the flashlight 1 (10) faces the earth magnetic north as in the step, the light module 128 can become brighter as in step 758 (for example, 'it can reach its brightest setting) . Conversely, when the flashlight 1G0 is rotated around it such that its front end faces the earth's magnetic south as in step 76, the light module 128 may not be defined as darker 762 (e.g., set to its darkest setting). In another embodiment, the flashlight 100 can be reversed. That is, when the flashlight _ rotates around its center, the light module 128 can become brighter if the front end of the flashlight 1 is facing south. And when the flashlight rotates around its center of rotation, if the front end of the flashlight 100 faces the earth's magnetic north, the light module 128 can be set to be dark. As previously described in connection with FIG. 9G, preferred magnetoresistive sensor circuit 514 can include 145907. Doc 201038127 includes a magnetometer 660 that produces output signals ADC_DC_XOUT 608, ADC_DC_YOUT 606, and ADC_DC_ZOUT 604 that can be lightly coupled to controller circuit 512. When the longitudinal axis of the flashlight 100 is horizontal and rotates about its center, the value on the ADC_DC_YOUT 606 will change as the longitudinal axis 110 of the flashlight 1 is changed because the Y-axis is set to coincide with the longitudinal axis 110 of the flashlight 100. . The other two outputs ADC_DC_XOUT 608 and ADC_DC_ZOUT 604 may change as the longitudinal axis 110 of the flashlight 100 changes depending on the vector component of the outputs projected onto the horizontal plane. Because the flashlight 100 is rotatable about its longitudinal axis, the X or Z axis can point to the earth. When this occurs, when the flashlight 1 is placed horizontally and rotated about the center of rotation, the vector component of this axis projected on the horizontal plane is zero and the output of this axis will have no change. If neither the X-axis nor the Z-axis are facing the Earth, the output of the X-axis and the Z-axis may change depending on the vector component projected on the horizontal plane when the flashlight 100 is placed horizontally and rotated about the center of rotation. Magnetic information is sent to controller 602 via ADC_DC_YOUT 606, ADC_DC_XOUT 608, and ADC_DC_ZOUT 604. Controller 602 can use the information on ADC_DC_YOUT 606, ADC_DC_XOUT 608, and ADC_DC_ZOUT 604 to determine if flashlight 100 has rotated and rotated about its center of rotation. Thus, flashlight 100 can use rotation about its center of rotation (or information on ADC_DC_YOUT 606, ADC_DC_XOUT 608, and ADC_DC_ZOUT 604) to determine the brightness on lamp module 128 or whether flashing on lamp module 128 is required. The brightness of the light module 128 can be 145907 by a frequency higher than the human eye can detect. Doc •63- 201038127 The frequency change lamp module 128 operates on a time loop to determine. The active time cycle on lamp module 128 can be generated by a sequence of high and low states on the LAMP_DRIVE 624 signal, which is driven by controller 602. This sequence of high and low states on signal LAMP_DRIVE 624 and other components on the load electrical path can cause bipolar transistor 5 70 and PMOS 5 72 to alternately conduct and not conduct. As the percentage of cycle time for switch conduction increases, the light module 128 will become brighter. On the other hand, as the percentage of cycle time for switching conduction decreases, the lamp module 128 will become darker. Methods of adjusting the brightness of the source other than the modulation time cycle can also be used, including, for example, adjusting the voltage, current, and/or power delivered to the source. The operational flow 740 shown in FIG. 10B can be implemented by software stored in the memory of the controller 602. The programmable controller 602 controls the flow of power through the lamp module 128 based on signals received from the output of the magnetoresistive sensor circuit 514. When controller 602 receives information on ADC_DC_YOUT 606, ADC_DC_XOUT 608, and ADC_DC_ZOUT 604, controller 602 can change some of its output signals (eg, LAMP_DRIVE 624) based on the execution of the software stored in controller 602. FIG. 10C is a flow diagram illustrating an exemplary motion sensitive operation 770 of the preferred flashlight 100. When the flashlight 100 has entered the motion sensitive signal mode 772, information about the preset intensity can be loaded from the memory 774 for the controller 602 to provide a control signal to control the brightness on the light module 128. In this embodiment, the memory can be an EEPROM embedded in the controller 602. Preset intensity information can be 145907. Doc -64- 201038127 == eg, minimum strength). Alternatively, the preset intensity information can be determined. The last used intensity before the same. Other intensities can be described in the pre-'==Fig.' flashlight (10) can perform multiple modes of operation.

Although turned out for low power, the flashlight will remain visible so that the user can easily determine the location of the flashlight in a dark dark environment. When the user needs a flashlight R 100, all that is required is to move the flashlight 100 and the detection of this movement by the flashlight 1 immediately turns the flashlight (10) into the highest (or other predetermined) brightness.

This battery configuration is advantageous in that the power provided by the three batteries is available without having to have a series electrical connection Many other flashlights are physically positioned end-to-end. This situation provides the benefit that the length of the flashlight barrel or other illuminator housing need not be dictated by the number of batteries that are installed end to end. More specifically, for example, a flashlight having a certain number of batteries can be shorter, which can be advantageous in certain applications.

If this is the case, the tip of the spring probe assembly 2136, 2138, 2140 can be used as an orientation finger when the icon 2 is laid.

lead. S In other embodiments, the icon 2180 can be placed beyond the circumference of the trailing cap 237〇. For example, the icon 2180 can be placed on the outer circumference of the middle of the tail cap 2370. In other embodiments, more or less than five icons may be used depending on the number of desired functional modes. Since the icon 218 is preferably engraved on the circumference 2371 of the tail cap 237A in this embodiment, the keying member between the upper switch housing 2360 and the board 145907.doc-120·201038127 is used for holding. The orientation of the board 2348 relative to the laser-engraved icon 2180. Alternatively, if a keyed component is not used, a calibration routine can be performed to align the icon with the board 23. If this is the case, calibration can be performed during manufacturing. If unintentional rotation occurs after fabrication, a program can be executed by the board 2348 to realign the icon with the board 2348. Figure 32 is a block diagram showing the circuit for the flashlight 23A. The circuit package includes a power supply 2330, a light source 2128, and a circuit board 2348. The circuit board 2348 can include a voltage regulator circuit and interface 1〇〇4, a load switch circuit 1006, a controller circuit 1008, and an accelerometer circuit 1〇1〇. Circuit board 2348 can also include an audio interface and speaker 518 and vibrator 52A. This situation may be desirable, for example, in situations where an audible or tactile response is responsive to the entry of a command (such as the selection of one or more modes as described below). Instead of placing the audio interface and speaker 518 and vibrator 520 on circuit board 23 48, one or both of them can be positioned off-board. The audio interface and speaker 518 and/or vibrator 520 need not be mounted on circuit board 2348 but may be included elsewhere in flashlight 300. Circuit board 2348 can include an I/O pad to engage an external device. The i/〇塾 can include top +4.5VDC 1012, bottom +4.5VDC 1014, GND 1016, LED_OUT 1018 and SWITCH 1020. Referring also to Fig. 30C, the I/O pad top + 4.5 VDC 1012 and GND 1016 can be coupled to the center contact 451 and the outer contact 434 of the battery case 2330, respectively. The bottom of the I/O pad +4.5 VDC 1014 and the SWITCH 1020 can be coupled to the buckle cover 152. When the user presses on the switch 埠 seal 16 8 , the actuation 145907.doc - 121 · 201038127 354 can be pushed forward to engage the buckle 152 to close the switch between the SWITCH 1020 and the +4 5VDc 1014. When the user releases the switch 埠 seal 168, the switch is opened and the SWITCH 1020 is no longer coupled to +4.5 VDC 1014. A detailed circuit schematic of an embodiment of circuit board 2348 is shown in Figures 33A-33D. FIG. 33A shows a circuit diagram of a preferred voltage regulator circuit 1004. The voltage regulator circuit 1004 can include a low dropout regulator 1〇〇2 that can be implemented by a DC linear voltage regulator operating with a small input-output differential voltage. The wei wire 1022 is an output from two diodes 1024, 1026 that can be driven by signal lines SWITCH 1020 and SW-ON 1046, respectively. This level preferably allows the lower voltage regulator from the signal line SWITCH 1020 or SW-ON 1046 to enable the low dropout regulator 1002. In the preferred embodiment, the output of the low dropout regulator 1 〇〇2 can be set to +3.3V 1028 for use as a source for other components such as controller circuit 1〇〇8. In one embodiment, a commercially available stand-alone LDO regulator (e.g., ISL9003AIRUNZ manufactured by Intersil Coperation) can be used. It should be understood that other types of linear regulator circuits can also be employed. The power supply voltage level from the battery (ie, +4.5 乂〇 (: 1012) can be monitored by the controller circuit 1008 via the signal line ADC_VBAT 1032. The signal line is input to 0 (: _¥8 八 1'1032 can be divided by a voltage divider + 4.5¥0 (:1012 is generated. The I/O pad SWiTCH 1020 can be used to generate the signal MOM 1048 for transmission to the controller circuit 1008 as an indication that the user is pressing on the switch 埠 seal 168 when the MOM 1048 is low. MOM 1048 It can be generated by an NPN bipolar transistor 1052. 145907.doc -122- 201038127 Figure 3 3B is a circuit diagram of a preferred controller circuit 1008. The controller circuit 1008 can include a controller 1030 having input and output connections. Input signals are received via signal lines ADC_VBAT 1032, Z-VOUT 1034, γ_VOUT 1036, X-VOUT 1038, SCK 1040, MISO 1042, MOM 1048, and RESET 1050. Controller 1030 can also be delivered via signal lines LOAD_ENABLE 1044 and SW_ON 1046 The signal is output. The power supply to the controller 1030 can be supported by a +3.3 V 1028 power supply. In one embodiment, the controller 1030 is a market controller with embedded memory, such as ATtiny 24, which is by Atmel Corporati. In another embodiment, the controller 1〇3〇 can be a microprocessor. In other embodiments, the controller 1030 can be a discrete circuit. Those skilled in the art should understand that Other types of controller circuits can also be used.Figure 33C shows a circuit diagram of a preferred load switching circuit 1〇〇6. In the embodiment of Figure 33C, the load switch can be implemented by NMOS 1054. The source coupling of PM〇s 1054 Connected to the top GND 1016' and the NMOS 1054 and q poles can be coupled to LED_OUT 1018. The gate of NMOS 1054 can be connected to LOAD_ENABLE 1044. Power can flow from LED_OUT 1 018 to GND 10 16 to form a switchable The part of the circuit of the current of the lamp module 2128. * Those skilled in the art should understand that other types of drivers and load switch circuits can be used. Figure 3 3D shows a schematic diagram of a preferred accelerometer circuit 1〇1〇. The accelerometer circuit 1010 can include outputs Z-VOUT 1034, Y-VOUT 1036, and χ_VOUT 1038, which can also be coupled to the controller circuit 1008 for further processing by 145907.doc -123. 201038127. Accelerometer circuit 1010 preferably includes an inertial sensor 1 〇 58 that can receive information from its internal sensing component and can provide an analog signal based on measurements from internal sensing components. The inertial sensor 1058 can be used to condition the earth's static gravitational field by providing acceleration information on, for example, three axes of mutually orthogonal axes (i.e., X, 丫, and z). The 3-axis accelerometer circuit 101 has a power supply VDD that can be supported by a +3.3V 1028 power supply. If the Z axis of the t-beat sensor 1 〇 58 points to the center of the earth, X and γ will have acceleration zero. However, due to the gravity of the Earth, Z will experience an acceleration rate of _1G. If the inertial sensor 1058 is flipped 18 turns. So that Z is facing away from the Earth, then χ and Y will remain at zero, but Z will have an acceleration of +1G. The inertial sensor 1 〇 58 can be attached to the circuit board 2348 such that the X, Y, and Z axes are fixed relative to the flashlight 2300. In the preferred embodiment, the inertial sensor 1058 is oriented on the plate 2348 such that the z-axis extends along the longitudinal axis of the flashlight 2300. Thus, when the flashlight 2300 is positioned horizontally, the Z axis also extends horizontally. In this position, 'when the flashlight 2300 is rotated left or right around the longitudinal axis of the flashlight 2300 to a different orientation, as the magnitude of the acceleration on the X and Y axes changes during rotation, the gravity information about X and Y The controller 1030 can be sent to the controller 1030 via X-VOUT 1038 and Y-VOUT 1036, respectively, to determine the orientation of the flashlight 2300. In other words, the orientation of the flashlight 2300 can be determined. The relative angular rotation of the flashlight 2300 can also be measured. When the flashlight 2300 is positioned horizontally, the 'Z axis' also extends horizontally. In this position, when X and γ are rotated left or right around the longitudinal axis of the flashlight 2300, as the magnitude of the acceleration on the X and γ axes changes during the rotation, the gravity information about X and Y can be respectively 145907.doc -124- 201038127 is sent to controller 1030 via X-VOUT 1038 and γ-νουτ 1036. The relative angular rotation can be calculated by controller 1030. Controller 1〇30 can use information on X-VOUT 1038 and Y-VOUT 1036 to determine if there is a rotation about the longitudinal axis of flashlight 2300. In the preferred embodiment, the switch for the flashlight can be located in the switch and tail cap assembly 2106. In this configuration, the initial orientation of the X and γ axes is unknown, so it can be based on the Earth's gravitational field on the X and γ axes in the initial orientation.

Calculate the starting value. Once the initial orientation is established, a subsequent angular measurement can be performed to track the rotation of the flashlight 2300. Preferably, the flashlight 2300 is positioned generally horizontally for the user to obtain a higher resolution (i.e., better sensing of the rotation of the X and gamma axes) when rotated. When the Ζ axis is inclined farther from the horizontal direction, a rotation error may occur. In operation, preferably, the flashlight 2300 is held at an angle relative to the horizontal. If the tilt is greater than 30. Preferably, the axis is monitored and the rotation input is ignored until the flashlight 2300 is tilted back to +/·3〇. Up to the window. However, in various embodiments, the above angles may be reduced or increased. In a preferred implementation, the inertial sensing Β 1 (4) may be a commercially available MEMS (MS), for example, LIS 394 AL, which is a 3-axis accelerometer made of a lamp &amp; It should be understood by those skilled in the art that other types of inertial sensor circuits can also be used. The variable brightness on the lamp module 2128 can be determined by varying the duty cycle on the lamp module 2128 at a frequency that is higher than the frequency that can be produced by the human eye. The active time cycle on the lamp module 2128 can be generated by the sequence of the state of the load switch circuit and the state of the low state. The load of the circuit is 145907.doc -125· 201038127 and can be deleted by the controller and other components. Drive together. If the time period of conduction is longer, the light module 2128 is brighter. On the other hand, if the time period of conduction is short, the lamp module 2128 is dark. The variable blink rate on the light module 2128 is also &lt;dry&quot; wax is determined by varying the effect on the light module 2128 at a frequency detectable by the human eye. The circuit can be the same as the circuit that supports the variable brightness that was previously inserted. As a combination, the flashing light with a brightness of 2128 on the lamp or a variable brightness can be used by the person. The frequency of the eye can form a duty cycle on the lamp module 2128 for the base to be produced. During the low cycle, the lamp module 2128 is turned off 'while during the high cycle' the lamp module 2128 can have and exceed the person The frequency of the frequency of the frequency of the debt can be measured. In other words, the high frequency of the low frequency action time cycle is present in the high frequency action time cycle: this function can be performed by the controller 1008. As indicated above, the 'better' is the flashlight test. It can be dropped in a variety of modes. The operation and access of these modes are discussed in a step-by-step manner. Figure 34 is a flow chart illustrating the preferred operation of the flashlight with fine accessibility and execution of various modes. When cutting off 27() 4, The circuit board 2348 can still be powered by the battery case 2330. Therefore, the flashlight 23_ continues to monitor the position of the flashlight 2300 and the position of the simultaneous _ momentary switch 2168. If the switch 2168 is depressed 27 〇 6, the flashlight 23GG is connected in the normal mode. Pass 2708. Tian hand ^• with 2300 in the normal mode is connected to the fourth (four), from the memory 2710 manned preset strength information for the controller to provide control signals to control 145907.doc -126, 201038127 lighting module (10) In the preferred embodiment, the memory can be used in the EE_ deleted by the controller. The preset strong information is the last used intensity before the flashlight 23GG is cut. Alternatively, the preset intensity information can be Predetermined setting (eg, maximum intensity). Other intensities may be predetermined. After loading the preset intensity information from the memory 2710, if the flashlight 23 is not held in the horizontal position when the switch is turned on or if the switch 168 is not The period 2312, which lasts more than the predetermined period of time, is continuously depressed, and the flashlight 23 continues in the normal mode 27 2714. In an embodiment, the predetermined period of time is one second. Other periods may be used. At this stage, the flashlight 23 00 is used as a normal flashlight with stable brightness and can be turned off when the switch 168 is pressed a second time. On the other hand, if the flashlight 2300 is held in the horizontal position when it is turned off, the switch 168 is continuously pressed for more than the predetermined time. The time period ^?, the flashlight 2300 can enter the new operating mode. The new operating mode can be specified as any of the following examples: dim light with variable brightness (DIM), flicker with variable flicker frequency STROBE, SOS mode with variable brightness (sos), motion sensitive signal mode (SIGNAL) or night light mode (NITE LITE). The new operating mode is determined by • the icon associated with the new mode. Selecting a particular icon is associated if the particular icon is facing up or toward the 12 o'clock direction while the switch 168 is continuously depressed 168 for more than a predetermined period of time period 2712 and the flashlight 2300 is held in the horizontal position when it is turned "on" Union mode 2716. For example, if the DIM icon 2370a faces up as shown in Figure 31B, then after step 2716, the DIM function mode is selected. On the other hand, for example. If the SOS icon 2370c faces up, after step 2716, select the 145907.doc -127- 201038127 SOS function mode. This interface simplifies the user's mode selection process. Any mode can be directly selected by having the desired mode associated icon face a predefined location so that the user does not need to guess or remember the sequence of operations. § When the flashlight enters the new function mode 2718 with the 2300, the preset intensity information can be loaded from the memory 2710 for the controller 1 to provide a control signal to control the lamp. The shell on the module 2128. The preset intensity information may be the last used intensity before the flashlight 23 is cut. Alternatively, the preset intensity information may be a predetermined setting (e.g., maximum intensity). Other strengths may be predetermined. In the present embodiment, when the current mode is the DIM mode, the str〇be mode, the SOS mode, or the SIGNAL mode, the last use intensity before the flashlight 23 is turned off is used as the preset intensity. On the other hand, if the current mode is NITE LITE mode, the maximum intensity is used as the preset intensity. At this point, if the switch 168 is released 2720, the flashlight 23 will be set at the preset intensity in the current functional mode to continue 2722 until the flashlight 23 is turned off by the specified method. For example, by squatting and then releasing switch 168, flashlight 2300 can recognize this sequence as a shutdown command and the flashlight will be severed at (10).右 The right flashlight 2300 rotates left or right around its projection spindle 2310 by 2724 and the switch 168 is still depressed 272()'. The amount of rotation can be calculated by the controller and the adjustment 2 7 2 6 is performed. For example, if the current mode of operation is a delete mode&apos;, the brightness of the flashlight 2300 can be varied based on the calculated amount of rotation. On the other hand, if the current mode of operation is str〇be mode, the frequency of the time loop can be varied based on the calculated amount of rotation (4). In a preferred implementation, the flashlight is illuminated 145907.doc -128 - 201038127 degrees to the intensity information stored in the memory before the flashlight 23 is rotated. When the flashlight 2300 is turned left or right by 10 days f ′ If the current operation mode is mode, mode or SIGNAL mode, the flashlight brightness is set to the maximum value. And when the flashlight 2300 is rotated 45 to the left or right. And 45. In the above case, set the brightness of the flashlight to the minimum value. In other words, when the flashlight 2300 is from 10. Left or right • Rotate to 45. The flashlight brightness can be changed linearly from maximum to minimum. ❹ *Tian Yue; when the operation mode is STROBE mode, the flashlight 2300 is rotated 10 to the left or right. Set the flashlight frequency to the maximum value. When the flashlight 2300 is rotated to the left or right by ". and 45. or more, the flashlight frequency is set to a minimum value. In other words, when the flashlight 23 is turned from 1 〇. Turn left or right to 45. When the flashlight frequency It can be changed linearly from the maximum value to the minimum value. Because the mode selection is based on the icon position at start-up, the rotating spindle along the projection spindle of the flashlight 2300 is only used for mode adjustment. Therefore, the adjustment can be rotated to the left or Rotating to the right is performed. The mode is adjusted to be symmetrical and mirrored across the virtual vertical plane of the projection spindle 2310 longitudinally across the flashlight 2300, thus, this feature helps users with left-handed or right-handed preferences. In the example, the maximum brightness is performed by providing a pulse current having 100% of the action time to the lamp module 2128 and the minimum brightness is 5% of the action time cycle. If appropriate brightness is found (for DIM, s〇s or SIGNAL mode) or frequency (for STROBE mode) while the flashlight 23 is rotated 145907.doc -129· 201038127 2724 to the left or right, the switch 168 can be released 2728 and The brightness or frequency present may be stored in the suffix and the selected mode function 273 〇. The flashlight may retain the brightness or frequency level until the next time the new setting is stored. On the other hand 'if switch 168 is released 2728 and The current mode is a signal wedge, and the motion sensitive signal operation can be performed by detecting whether there is a left or right rotation of the technical spindle 23 1 手 along the flashlight 23 00. If the rotation is detected, The flashlight 23 is turned on. If the flashlight 23 is returned to the previous position, the flashlight 2300 can be turned off. In other words, the flashlight 23 can be connected by rotating it to the left or right and then rotating it back. The two-state switching between the pass and the cut. The flashlight 2300 can be cut 2734 by a specified method. For example, if the switch 168 is depressed and then released, the flashlight 2300 can recognize this sequence as the shutdown command 2732 and the flashlight 2300 Will be cut off 2734. Those skilled in the art will appreciate that the flow chart 7〇2 illustrated in Figure 14 is an example and other types of operations may be employed. The operational flow 27〇2 shown in Figure 34 may be The software stored in the memory of the controller 1〇〇8 is implemented. Thus, the programmable controller 1〇〇8 controls the sequence of operations based on signals received from the output of the 3-axis accelerometer circuit 1010. When the controller 1008 When the outputs χ_ν〇υτ 1〇38 and γ_VOUT 1036 of the accelerometer circuit 1010 receive information, the controller 1〇〇8 can change its execution sequence based on this information. Also, the stylized controller 1〇〇8 is based on self- The signal received by the output of the accelerometer circuit 1控制 controls the power flow through the lamp module 2128. When the control is crying 1〇自χ-ν〇υτ brain and MT1GW_, the capsule 145907.doc •130- 201038127 can be stored based on Some of the numbers in the controller 1008. The execution of the software to change its round-trip signal can cause a change in the output of the accelerometer circuit 1010. The type of movement can also be used as a command to change the characteristics of the flashlight 23〇〇. Accordingly, the present disclosure is limited to (iv) the movement described herein in connection with the controller coffee.

Fig. 35 is a flowchart W for explaining a method 1110 for operating a flashlight in a night light operation mode. The method 1110 shown in Figure 35 for operating the flashlight 2300 in the nightlight mode of operation is shown in detail in the method provided by Figure (10). When the night light mode is selected, step 9G2 thus corresponds to step 2718 in Fig. 34. When the flashlight 2300 enters the night light mode in step 902, the controller 1GG8 is preferably configured such that the light source of the flashlight 23 (10) initially provides light at a level of 7C. After the flashlight 2300 enters the night light mode in step 9A2, the program controller (10) 8 is programmed to output the command to the load switch 1006, the audio interface and the speaker 518 and/or the vibrator 520 to provide the selected one in step 1912. And enter the visual, audio and/or tactile cues of the night light mode. This prompt provided in step 1912 is advantageous because in this embodiment, in the absence of this prompt, there will be no direct operational change in the brightness of the light source before the timer expires at step 19〇8. Accordingly, providing a visual, audio or tactile cue in step 1912 will inform the user of the selection of the night light mode and utilize the flashlight 2300 more satisfactorily than the user. The visual cue can be a simple flash of the flashlight being turned off and then turned back on. Or ' it can be a series of two or more flashes. In order to provide an audio prompt in steps 145907.doc-131 - 201038127 1912, in addition to or instead of the visual cue, the programmable controller 1008 can output a sequence, sound or via the audio interface and speaker 518 (see FIG. The different tones are provided, and the audio interface and speaker 518 are in communication with the controller ι_. Alternatively, the tactile cue can be provided via a vibrator 520 (see Figure 32) that communicates with the controller (10). Once the visual, audio or tactile cues are performed in step 1912, the timer can be re-started in step 1904. The timer is used to determine the time period before the flashlight begins to dim. Preferably, whenever a collision of a predefined magnitude is sensed by the controller 1008 based on one or more inputs from the accelerometer 1〇1, the timer is reset to cause entry in step 9〇2 After the night light mode, the timer is allowed to expire and the brightness of the light source 1〇1 is darkened only after the flashlight 2300 remains stationary for a predetermined preset period of time (such as 15 or 30 seconds). Therefore, as long as the flashlight continues to move back and forth with sufficient force to cause the necessary change in acceleration, the flashlight 23 will not dim. In some embodiments, it may be desirable to allow the user to add additional time to the timer, thereby extending the amount of time required to pass through step 1908 without requiring controller 1008 to sense an acceleration of sufficient magnitude to be at step 1916. The redundancy of the light source 101 is made dark. In the embodiment shown in Figure 32, the controller 1008 is programmed to allow the user to adjust the timer. In the illustrated embodiment, once the night light mode is entered in step 902, the user can adjust the timer without releasing the momentary switch. On the other hand, once the user releases the momentary switch ', it can no longer adjust the timer. In the preferred embodiment, the timer is initially set to expire in step 1904 for a period of 30 seconds 145907.doc -132 - 201038127. If the momentary switch 168 is released at any time after entering the night light mode without adjusting the timer, the controller 1〇〇8 will simply wait in step 19〇8 before dimming the brightness of the light source ίο! in step 1916. The timer expires after the 6th period has elapsed. However, as noted above, it is preferred that the controller 1008 resets the timekeeping state whenever the flashlight 23 is sensed to move with sufficient force. It continues to step 1908 to expire the timer. On the other hand, if the controller determines in step 272 that the momentary switch 0 168 is not released, the user can adjust the preset period of the timer, whereby in step 916 the redundancy of the source 101 is darkened before it becomes dark. In the case of a delay, the period of time must elapse. For example, in the illustrated embodiment, if the controller flashes the determination flashlight 2 around its projection wire 31〇7 left or right while the momentary switch 168 has been continuously depressed, in step 2724, then The amount of rotation can be calculated by the controller 1008 and the timer 19〇6 is adjusted based on the amount of rotation. The timer may be incremented each time the flashlight 2300 is rotated to the left or right and then rotated back to the center (eg, 1 15 seconds or 3 seconds). In other words, if the waiting time outside the forehead is desired, step 2724 may be repeated. 1906, the user may release the momentary switch as long as it is determined in step 2728 that the momentary switch remains depressed. The timer has increased the desired amount. When the release of the momentary switch is detected in step 2728, the timer will begin. • Difficult until it is determined in the step calendar that it has expired. As mentioned above, the timer is reset every time a sufficient amount of force is detected (now reset to the adjusted timer preset) to allow The timer expires only if the flashlight remains stationary (or relatively stationary) for a period of time adjusted. Although "10:2 is better for each - left or right rotation only adjusts ^ seconds to 145907.doc -133- 201038127 3 〇 seconds ^ eye to hour, but the timer can be gradually increased by any amount in step (10), including (for example) 〖minutes or 5 minutes. As each flashlight rotates left or left and right in step _ Lieutenant The timer adjusts the increment of the offset. The timer adjustment performed in step 19〇6 can also be performed based on the amount of rotation of the flashlight 2鸠. For example, the timer can be rotated at least 15 and less than 3 inches in the flashlight. It is increased by 15 seconds and rotated 3 〇 or 3 向 to the left or right in the flashlight 2300. When the above is increased by 3 Hz, in the other embodiment, other time or angle can be used. For example, the device can be used in The flashlight 2300 is rotated left or right by at least 15 and less than %. An additional five minutes is added and the timer can be added for an additional ten minutes when the flashlight is rotated to the left or right by 30 or more. Providing a visual, audio or tactile cue when the timer is incremented in step 1906. Preferably, the cue corresponds to an amount of time added to the timer or an adjusted period of the timer to cause the user to know that the timer has increased Once the timer expires at step 1908, the brightness of the light source 1〇1 of the flashlight 23 can be reduced in step 1916. In this embodiment, the light source 1〇1 of the flashlight 2300 can be gradually dimmed until Da Its minimum brightness. In another embodiment, the light source 〇1 of the flashlight 23 can be gradually darkened until it is finally completely cut off. Once the flashlight 2300 has been darkened in step 1916, it can continue to provide the lowest ( Or other presets) brightness until the flashlight 23 债 detects the collision in step 1918, at which time the brightness of the flashlight 2300 can be increased to the brightness level 1920 stored in the memory. In this embodiment, the flashlight is 23〇〇 145907.doc • 134- 201038127 Light source 1 (H brightness is set to the brightness level previously stored in the memory by the user in dim mode. However, in other embodiments 'flashlight 2300 can be used The brightness of the light source 101 is simply adjusted to its highest brightness level. Once the enthalpy has been incremented in step 1920, the timer will be adjusted in step 1906, then the timer will be reset to the adjusted period or reset to the pre-Han slave in step 1910. The routine then reverts to step 272 and then proceeds to step 1908 where controller 1008 monitors whether the reset timer has expired. Moreover, 0 is preferably reset every time a sufficient amount of movement is detected to cause the brightness of the light source 1 〇 1 of the flashlight 2300 to dim only when the flashlight 23 〇〇 remains stationary or does not move quickly enough. As described in δ, FIG. 32 and FIG. 33D, the accelerometer circuit 1〇1〇 has an output that can also be coupled to the controller circuit 1008.
