DETAILED DESCRIPTION

In the drawings and description below, similar parts are marked with the same reference numerals in the specifications and drawings, respectively. The drawings are not necessarily to scale. Certain features of the invention may be shown to exaggerated scale or somewhat schematically and some details of conventional elements may not be shown for the sake of clarity and accuracy. The present invention is susceptible to embodiments of different types. Specific embodiments are described in detail and shown in the drawings, with the understanding that the present finding should not be considered an exemplification of the principles of the invention, nor is it intended to limit the invention to the included illustrations and descriptions. It should be fully recognized that the different teachings of the embodiments discussed below may be employed separately or in any suitable combination to produce the desired results. The various features mentioned above, as well as other features and features described in more detail herein, will be readily apparent to those skilled in the art after reading the detailed description of the following embodiments and consulting the corresponding drawings.

Initially, with reference to Fig. 1, a system 100 for viewing a three-dimensional ("3D") film on a movie screen 102 includes a pair of 3D glasses 104 having a left shutter 106 and a right shutter 108. In one form By way of example, 3D glasses 104 include a frame and shutters 106 and 108 are provided in the form of left lens and right viewing lens mounted and supported within the frame.

In an exemplary embodiment, shutters 106 and 108 are liquid crystal cells that open when the cell changes from opaque to transparent and the cell closes when it again changes from transparent to opaque. Transparent, in this case, is defined as transmitting sufficient light for a user of 3D glasses 104 to see a projected image on movie screen 102. In an exemplary embodiment, the user of 3D glasses 104 may be able to view the image. projected onto film screen 102 when the liquid crystal cells of shutters 106 and / or 108 of 3D glasses 104 become between 25 and 30 percent transmissible. Thus, a shutter liquid crystal cell, 106 and / or 108, is considered open when the liquid crystal cell becomes between 25 and 30 percent transmissible. The shutter liquid crystal cells 106 and / or 108 may also transmit more than 25-30 percent light when the liquid crystal cell is open.

In an exemplary embodiment, shutters 106 and 108 of 3D glasses 104 include liquid crystal cells having a PI cell configuration using a low viscosity, high refractive index liquid crystal material such as Merck MLC6080. In an exemplary embodiment, the thickness of the 'PI' is adjusted for those who, in their relaxed state, form a halfwave retarder. In an exemplary embodiment, the PI cell is thicker so that the half wave state is reached before reaching full relaxation. One of the suitable liquid crystal materials is MLC6080, manufactured by Merck, but any liquid crystal with sufficiently high optical anisotropy, low rotational viscosity and / or birefringence can be used. Shutters 106 and 108 of 3D glasses 104 may also use a small gap between cells, including, for example, a 4 micron gap. In addition, a liquid crystal with a sufficiently high refractive index and low viscosity may also be suitable for use on shutters 106 and 108 of 3D glasses 104. In an exemplary embodiment, shutter PI cells 106 and 108 , of the 3D glasses 104 function according to an electrically controlled birefringence principle ("ECB"). Birefringence means that the PI cell has different refractive indices, when none or a small capture voltage is applied, for light with polarization parallel to the long dimension of 'PI' cell molecules and for light with polarization perpendicular to the long dimension, at e huh. The difference no-ne = An is optical anisotropy. An * d, where d is the thickness of the cell, is optical thickness. When Anxd = 1 / 2A, cell PI is acting as a halfwave retarder when the cell is placed at 45 ° to the polarizer axis. Therefore, optical thickness is important, not just thickness. In one exemplary embodiment, the shutter 'PI' cells 106 and 108 of the 3D glasses 104 are made optically too thick, which means that An * d> 1 / 2A. Higher optical anisotropy means thinner cell, and faster cell relaxation. In an exemplary embodiment, when stress is applied, the long axes of the shutter PI cell molecules 106 and 108 of the 3D glasses 104 are perpendicular to the substrates - homeotropic alignment and thus there is no birefringence in this state and, As the polarizers have their transmission axes crossed, no light is transmitted. In an exemplary embodiment, cross-polarized PI cells are supposed to function in normally white mode and transmit light when no voltage is applied. PI cells with the transmitter axes of the parallel-oriented polarizers operate in a normally black mode, that is, they transmit light when a voltage is applied. In an exemplary embodiment, when the high voltage removed from the 1PI1 cells begins to open the shutters 106 and / or 108. This is a relaxation process, which means that the liquid crystal ("LC") molecules ) in the PI cell return to equilibrium, that is, the molecules align with the alignment layer, ie the direction of friction of the substrates. The 'PI1 cell relaxation time depends on the cell thickness and the rotational viscosity of the liquid.

In general, the thinner the PI cell, the faster the relaxation. In an exemplary embodiment, the important parameter is not the interval between cells PI, d itself, but the product And, where Δη is the liquid birefringence of the LC. In one exemplary embodiment, in order to provide maximum light transmission in its open state, the frontal optical delay of cell 'PI1, And, should be λ / 2. Higher birefringence allows for a thinner cell and therefore faster cell relaxation. In order to provide the fastest possible changing liquids with low rotational viscosity and highest birefringence, Δη (like MLC 6080 by EM industries) is used.

In one exemplary embodiment, in addition to the use of low rotational viscosity liquids and higher birefringence in 'PI' cells, to achieve faster opaque to transparent state changeover, 'PI' cells are made optically longer. thick to reach the half-wave state before reaching full relaxation. Generally, the thickness of the 'PI' is adjusted so that in its relaxed state it forms a half-wave retardant. However, making 'PI' cells optically too thick for the half-wave state to be reached before reaching full relaxation results in faster switching from opaque to transparent state. Thus, the shutters 106 and 108 of the exemplary embodiments provide enhanced aperture velocity compared to prior art LC shutter devices which, in an exemplary experimental embodiment, provided unexpected results.

In an exemplary embodiment, a capture voltage may then be used to stop the rotation of the LC molecules in the 'PI' cell before they spin too far. By stopping the rotation of the LC molecules in cell 1PI 'in this manner, light transmission is maintained at or near its peak value. In an exemplary embodiment, the system

100 further includes a signal transmitter 110, which has a central processing unit ("CPU") 110a, which transmits a signal toward film screen 102. In an exemplary embodiment, the transmitted signal is reflected from the video screen. film 102 towards signal sensor 112. The transmitted signal may be, for example, one or more of the following: an infrared ("IR") signal, a visible light signal, multi-color signal or white light. In some embodiments, the transmitted signal is transmitted directly towards the signal sensor 112 and therefore may not be reflected from the movie screen 102. In some embodiments, the transmitted signal may be, for example, a radio frequency signal (" RF ") that is not reflected from the movie screen 102. The signal sensor 112 is coupled

operable to a CPU 114. In an exemplary embodiment, signal sensor 112 detects the transmitted signal and communicates the presence of the signal to CPU 114. CPU 110a and CPU 114 may, for example, each include a programmable controller. general purpose, an application specific integrated circuit ("ASIC"), an analog controller, a localized controller, a distributed controller, a programmable state controller, and / or one or more combinations of the above devices.

The CPU 114 is operably coupled to a left shutter controller 116 and a right shutter controller 118 to monitor and control the operation of the shutter controllers. In an exemplary embodiment, the left and right shutter controllers 116 and 118 are in turn operably coupled to the left and right shutters 106 and 108 of the 3D glasses 104 to monitor and control the operation of the shutters. left and right shutters. Shutter controllers 116 and 118 may, for example, include a general purpose programmable controller, an ASIC, an analog controller, an analog or digital switch, a localized controller, a distributed controller, a programmable state controller, and / or one or more combinations of the above devices.

A battery 120 is operably coupled to at least CPU 114 and provides power to operate one or more of the following: the CPU, signal sensor 112, and shutter controllers 116 and 118 of the 3D glasses 104. One Battery sensor 122 is operably coupled to CPU 114 and battery 120 to monitor the amount of charge remaining in the battery.

In an exemplary embodiment, CPU 114 may monitor and / or control the operation of one or more of the following: signal sensor 112, shutter controllers 116 and 118 and battery sensor 122. Alternatively, or in in addition, one or more of the following: signal sensor 112, shutter controllers 116 and 118 and battery sensor 122 may include a separate dedicated controller and / or a plurality of controllers which may or may not also monitor and / or controlling one or more of the following: signal sensor 112, shutter controllers 116 and 118, and battery sensor 122. Alternatively, or in addition, the operation of CPU 114 may be at least partially distributed among one or more. of the other elements of the 3D glasses 104.

In an exemplary embodiment, the signal sensor 112, the CPU 114, the shutter controllers 116 and 118, the battery 120 and the battery sensor 122 are mounted and supported within the frame of the 3D glasses 104. movie screen 102 is positioned within a movie theater, then a projector 130 may be provided to project one or more video images onto the movie screen. In an exemplary embodiment, the signal transmitter 110 may be positioned close to or included within the projector 130. In an exemplary embodiment, the projector 130 may include, for example, one or more of the following: a projector device an electromechanical projector device, a movie projector, a digital video projector, or a computer screen for displaying one or more video images on movie screen 102. Alternatively, or in addition to movie screen 102, a television ( "TV") or other video display device may also be used such as a flat screen TV, a plasma TV, an LCD TV or other display device to display images for viewing by a 3D glasses, which may include, for example, signal transmitter 110, or an additional signal transmitter for signaling to 3D glasses 104, which may be positioned near and / or within the surface of the display device screen.

In an exemplary embodiment, during operation of system 100, CPU 114 controls the operation of shutters 106 and 108 of 3D glasses 104 as a function of signals received by signal sensor 112 from signal transmitter 110 and / or as a function of signals received by the CPU from the battery sensor 122. In an exemplary embodiment, the CPU 114 may orient the left shutter controller 116 to open the left shutter 106 and / or orient the shutter controller. right 118 to open the right shutter 108.

In an exemplary embodiment, the shutter controllers 116 and 118 control the operation of the shutters 106 and 108 respectively by applying a voltage to the shutter liquid crystal cells. In an exemplary embodiment, the voltage applied to the shutter liquid crystal cells 106 and 108 alternates between negative and positive. In an exemplary embodiment, the shutter liquid crystal cells 106 and 108 open and close in the same manner, regardless of whether the applied voltage is positive or negative. Alternation of the applied voltage prevents material from the liquid crystal cells of the shutters 106 and 108 from plating outward on the cell surfaces.

In an exemplary embodiment, during operation of the system 100, as illustrated in Figs. 2 and 3, the system may implement a left-right shutter method 200 wherein, if at 202a, the left shutter 106 will be closed and the Right shutter 108 will open, then at 202b, a high voltage 202ba is applied to the left shutter 106 and no voltage 202bb followed by a small capture voltage 202bc that is applied to the right shutter 108 by the shutter controllers 116 and 118 respectively. In an exemplary embodiment, applying high voltage 202ba to the left plug 106 closes the left plug and applying no voltage to the right plug 108 initiates the opening of the right plug. In an exemplary embodiment, the subsequent application of a small capture voltage 220bc to the right shutter 108 prevents liquid crystals in the right shutter from rotating too far during opening of the right shutter 108. As a result, at 202b, the shutter The left 106 is closed and the right shutter 108 is opened.

If at 202c, the left shutter 106 will open and the right shutter 108 will be closed, then at 202d, a high voltage is applied to the right shutter 108 and no voltage followed by a small arrest arresting voltage 202dc that is applied to the left shutter 106 by the shutter controllers 118 and 116 respectively. In an exemplary embodiment, applying high voltage to the right shutter 108 closes the right shutter and applying no voltage to the left shutter 106 initiates the opening of the left shutter. In an exemplary embodiment, subsequent application of a small capture voltage 202dc to the left shutter 106 prevents liquid crystals in the left shutter from rotating too far during opening of the left shutter 106. As a result, at 202d, the left shutter 106 is opened and right shutter 108 is closed. In an exemplary embodiment, the magnitude

The capture voltage used in 202b and 202d ranges from about 20% to the magnitude of the high voltage used in 202b and 202d. In an exemplary embodiment, during operation of system 100, during method 200, during the time the left shutter 106 is closed and the right shutter 108 is opened at 202b, a video image is presented to the right eye and during the time the left shutter 106 is opened and the right shutter 108 is closed at 202d, a video image is presented to the left eye. In an exemplary embodiment, the video image may be displayed on one or more of the following: a movie theater screen 102, an LCD television screen, a digital light processing television ("DLP"), a DLP projector, a plasma screen and the like.

In an exemplary embodiment, during operation of system 100, CPU 114 will direct each shutter 106 and 108 to open at the same time as the intended image for the respective shutter and the viewer's eye is displayed. In an exemplary embodiment, a synchronization signal may be used to cause the shutters 106 and 108 to open at the right time. In an exemplary embodiment, a signal from

The sync is transmitted by the signal transmitter 110 and the sync signal may, for example, include an infrared light. In an exemplary embodiment, the signal transmitter 110 transmits the sync signal towards a reflective surface and the surface reflects the signal to the signal sensor 112 positioned and mounted within the frame of the 3D glasses 104. The reflective surface could be, for example, a movie theater screen 102 or other reflective device located on or near the movie screen such that the wearer of the 3D glasses 104 is generally facing the reflector while watching the movie. In an exemplary embodiment, signal transmitter 110 may send the synchronization signal directly to sensor 112. In an exemplary embodiment, signal sensor 112 may include a photodiode mounted and supported within the frame of the 3D glasses. 104.

The synchronization signal may provide a pulse at the beginning of each shutter 200 left-right lens sequence. The synchronization signal may be more frequent, for example providing a pulse to guide the aperture of each shutter, 106 or 108. The sync signal may be less frequent, for example providing one pulse once per shutter sequence 200, once every five shutter sequences or once every 100 shutter sequences. The CPU 114 may have an internal timer to maintain proper shutter sequencing in the absence of a synchronization signal.

In an exemplary embodiment, the combination of narrow-gap viscous liquid crystal material between the cells in the shutters 106 and 108 may result in a cell that is optically too thick. Liquid crystal in shutters 106 and 108 block light transmission when voltage is applied. Upon removal of the applied stress, the molecules in the liquid crystals in the shutters 106 and 108 rotate back to the orientation of the alignment layer. The alignment layer guides the molecules in the liquid crystal cells to allow light transmission. In a liquid crystal cell that is optically too thick, the liquid crystal molecules rotate rapidly upon removal of energy and therefore rapidly increase light transmission, but then the molecules rotate too far and light transmission decreases. The time from when the rotation of the liquid crystal cell molecules begins until light transmission stabilizes, that is, the rotation of liquid crystal molecules stops is the real time for the exchange.

In an exemplary embodiment, when the shutter controllers 116 and 118 apply the small capture voltage to the shutters 106 and 108, this capture voltage stops the rotation of the liquid crystal cells in the shutters before they spin too far. far. By stopping the rotation of the molecules in the liquid crystal cells in the shutters 106 and 108 before they rotate too far, the light transmission through the molecules in the liquid crystal cells in the shutters is maintained at or near its peak value. this value. Thus, the effective changeover time is from when the liquid crystal cells in the shutters 106 and 108 begin their rotation until the rotation of the molecules in the liquid crystal cells is stopped at or near the peak point of light transmission. him.

Referring now to Fig. 4, transmission refers to the amount of light transmitted through a shutter, 106 or 108, where a transmission value of 1 refers to the high point, or a point close to the maximum, transmission. of light through the shutter's liquid crystal cell 106 or 108. Thus, for a shutter, 106 or 108, to be able to transmit its maximum of 37% light, a transmission level of 1 indicates that the shutter, 106 or 108, is transmitting its maximum, 37% of available light. Of course, depending on the particular liquid crystal cell used, the maximum amount of light transmitted by a shutter 106 or 108 may be any amount, including, for example, 33%, 30% or significantly more or less. As illustrated in Fig. 4, in an exemplary experimental embodiment, a shutter 106 or 108 was operated and light transmission 400 was measured during the operation of method 200. In the exemplary experimental embodiment of the shutter 106 or 108, the shutter closed at approximately 0.5 milliseconds, then remained closed during the first half of the shutter cycle for about 7 milliseconds, then the shutter was opened at about 90% of the maximum light transmission in about one millisecond. , and then the shutter remained open for about 7 milliseconds and was then closed. By comparison, a commercially available shutter was also operated during the operation of method 200 and exhibited light transmission 402. Shutter light transmission 106 and 108 of the present exemplary embodiments during operation of method 200 achieved about 25 to 30 percent of the transmitting capacity, that is, about 90 percent of the maximum light transmission, as shown in Fig. 4, in about one millisecond, while the other shutter reached only about 25 to 30 percent. percent transmittance, or about 90 percent of the maximum light transmission, as shown in Fig. 4, after about 2.5 milliseconds. Thus, shutters 106 and 108 of the present exemplary embodiments provided significantly more responsive operation than commercially available shutters. This was an unexpected result.

Referring now to Fig. 5, in an exemplary embodiment, system 100 implements a method of operation 500 wherein, at 502, signal sensor 114 receives an infrared sync pulse from the transmitter. signal 110. If 3D glasses 104 are not in RUN MODE at 504, then CPU 114 determines if 3D glasses 104 are in OFF MODE at 506. If CPU 114 determines that 3D glasses 104 are not in DES MODE at 506 , then CPU 114 continues normal processing at 508 and then returns to 502. If CPU 114 determines that 3D glasses 104 are in OFF MODE at 506, then CPU 114 clears the Sync Inverter ("SI") indicators. and validation at 510 to prepare CPU 114 for the next coded signals, initiates a warm-up sequence for shutters 106 and 108 at 512 and then proceeds with normal operations 508 and returns to 502.

If 3D glasses 104 are in RUN MODE at 504, then CPU 114 determines if 3D glasses 104 are already set to 514 encoding. If 3D glasses 104 are already set to 514 encoding, then CPU 114 continues operations. 508 and proceeds to 502. If the 3D glasses 104 are not yet configured for 514 encoding, then CPU 114 checks to determine if the incoming signal is a three-pulse synchronization signal at 516. If the signal that input is not a three-pulse synchronization signal at 516, then CPU 114 continues normal operations at 508 and proceeds to 502. If the input signal is a three-pulse synchronization signal at 516, then CPU 114 receives configuration data from signal transmitter 110 in 518 using signal sensor 112. CPU 114 then decodes the received configuration data to determine if it is valid at 520. If the configuration data r If they are valid at 520, then CPU 114 checks to see if the new configuration ID ("CONID") resembles the previous CONID in 522. In an exemplary embodiment, the previous CONID may be stored on a memory device. such as a nonvolatile memory device operably coupled to the CPU 114 during the manufacture or field programming of the 3D glasses 104. If the new CONID does not resemble the previous CONID in 522, then the CPU 114 directs shutters 106 and 108 of 3D glasses 104 into TRANSPARENT MODE at 524. If the new CONID does not resemble the previous CONID at 522, then CPU 114 sets the SI and CONID indicators to trigger the sequence. shutters in NORMAL MODE for viewing three-dimensional images in 526.

In an exemplary embodiment, in RUN or NORMAL MODE, the 3D glasses 104 are fully operational. In an exemplary embodiment, in OFF MODE, 3D glasses are not operational. In an exemplary embodiment, in NORMAL MODE, the 3D glasses are operational and can implement method 200.

In one exemplary embodiment, the signal transmitter 110 may be located near the cinema projector 130. In an exemplary embodiment, the signal transmitter 110, among other functions, sends a sync signal ("sync signal"). signal sensor 112 of the 3D glasses 104. The signal transmitter 110 may instead, or in addition, receive a synchronization signal from the movie projector 130 and / or any screen and / or any emitting device. In an exemplary embodiment, a coding signal may be used to prevent 3D glasses 104 from operating with a signal transmitter 110 that does not contain the correct coding signal. Also, in an exemplary embodiment, the coded signal from the transmitter will not correctly trigger 3D glasses 104 that are not equipped to receive and process the coded signal. In an exemplary embodiment, the signal transmitter 110 may also send coding data to the 3D glasses 104. Now, with respect to Fig. 6, in an exemplary embodiment, during operation, system 100 implements a method 600 where at 602 the system determines if signal transmitter 110 has been reset because the power has just been turned on at 602. If signal transmitter 110 has been reset because the power has just been turned on at 602 then the transmitter generates a new random sync reversal indicator at 604. If signal transmitter 110 did not have a reset status at 602, then signal transmitter 110 CPU 110a determines whether the same synchronization coding was used for more than 602. a default amount of time at 606. In an exemplary embodiment, the default time at 606 could be four hours or the length of a typical movie or any other adequate time. If the same sync coding was used for more than four hours at 606, then CPU 110a of signal transmitter 110 generates a new sync reversal indicator at 604.

CPU 110a of signal transmitter 110 then determines whether the signal transmitter is still receiving a signal from projector 130 at 608. If signal transmitter 110 is not yet receiving a signal from projector 130 at 608, then signal transmitter 110 you can use your own internal synchronization generator to continue sending synchronization signals to signal sensor 112 at the appropriate time at 610.

During operation, signal transmitter 110 may, for example, alternate between two-pulse synchronization signals and three-pulse synchronization signals. In one exemplary embodiment, a two-pulse sync signal directs the 3D glasses 104 to open the left shutter 108 and a three-pulse sync signal directs the 3D glasses to open the right shutter 106. In an exemplary embodiment , signal transmitter 110 may send a coding signal after each η signal.

If signal transmitter 110 determines that it should send a three-pulse sync signal at 612, then the signal transmitter determines the signal count since the last coding cycle at 614. In an exemplary embodiment, the signal transmitter Signal 110 sends a coding signal only once every ten signals. However, in an exemplary embodiment, there could be more or less signal cycles between the encoding signals. If CPU 110a of signal transmitter 110 determines that this is not the nth three-pulse synchronization at 614, then the CPU directs the signal transmitter to send a standard three-pulse synchronization signal at 616. If the synchronization signal is the nth three-pulse signal, then signal transmitter 110 CPU 110a encodes the data at 618 and sends a three-pulse synchronization signal with configuration data embedded at 620. If signal transmitter 110 determines that it should not send a three-pulse sync signal at 612, then the signal transmitter sends a two-pulse sync signal at 622.

Referring now to Figs. 7 and 8, in an exemplary embodiment, during operation of system 100, signal transmitter 110 implements a method of operation 700 wherein the synchronization pulses are combined with coded configuration data and then transmitted by signal transmitter 110. In particular, signal transmitter 110 includes a firmware internal clock that generates a regulator signal 800. At 702, CPU 110a of signal transmitter 110 determines whether regulator signal 800 is at the beginning of the signal. clock cycle 802. If signal transmitter 110 CPU 110 determines that the regulator signal 800 is at the beginning of clock cycle 702, then the signal transmitter CPU checks to see if a configuration data signal 804 is high or low at 704. If the 804 configuration data signal is high, then an 806 data pulse signal is set to a high value at 706. If the 804 configuration data signal is low xx, then the data pulse signal 806 is set to a low value at 708. In an exemplary embodiment, the data pulse signal 806 may already include the synchronization signal. Thus, data pulse signal 806 is combined with synchronization signal 710 and transmitted by signal transmitter 110 at 710.

In an exemplary embodiment, the coded form of the configuration data signal 804 may be sent during each synchronization signal sequence after a predefined number of synchronization signal sequences incorporated with the coated synchronization signal sequences. with the sync signal sequences, or combined with the sync signal sequences - before or after the coding operation. In addition, the coded form of the configuration data signal 804 could be sent in the two-pulse or three-pulse synchronization signal, or both, or signals with any other number of pulses. Further, encoded configuration data could be transmitted between transmission of the sync signal sequence with or without encoding the sync signals at the transmission points.

In an exemplary embodiment, configuration data signal coding 804, with or without the synchronization signal sequence, may be provided, for example, using Manchester coding.

Referring now to Figs. 2, 5, 8, 9 and 10, in an exemplary embodiment, during operation of system 100, the 3D glasses 104 implement a method of operation 900 in which, in 902, the CPU 114 of 3D glasses 104 checks for a timeout for enabled mode. In an exemplary embodiment, the presence of a timeout for the activated mode at 902 is provided by a 902a regulator signal that has a high pulse 902aa with a duration of 100 milliseconds that may occur every 2 seconds, or other period of time. default time. In an exemplary embodiment, the presence of the high pulse 902aa indicates a timeout for the activated mode.

If CPU 114 detects an activation timeout at 902, then the CPU checks for the presence or absence of a synchronization signal using signal sensor 112 at 904. If CPU 114 detects a synchronization signal at 904, then the CPU places the 3D glasses 104 into a TRANSPARENT mode of operation at 90 6. In an exemplary embodiment, in CLEAN MODE of operation, the 3D glasses implement at least portions of one or more of methods 200 and 500, receiving synchronization pulses and / or processing configuration data 804. In an exemplary embodiment, in TRANSPARENT mode of operation, the 3D glasses may provide at least the operations of method 1300, described below.

If the CPU 114 does not detect a synchronization signal at 904, then the CPU puts the 3D glasses 104 into an OFF operating mode at 908 and then at 902, the CPU checks for a timeout for the enabled mode. In an exemplary embodiment, in OFF mode, the 3D glasses do not provide the features of NORMAL or TRANSPARENT modes of operation.

In an exemplary embodiment, method 900 is implemented by 3D glasses 104 when the 3D glasses are in OFF mode or TRANSPARENT mode.

Now, with reference to Figs. 11 and 12, in an exemplary embodiment, during operation of system 100, the 3D glasses 104 implement a heating method 1100 of operation wherein, in 1102, the CPU 114 of the 3D glasses checks if there is power on in the 3D glasses. In an exemplary embodiment, the 3D glasses 104 may be turned on by a user by activating an activation switch or by an automatic activation sequence. Upon activation of the 3D glasses 104, the shutters 106 and 108 of the 3D glasses may, for example, require a warm-up sequence. The shutter liquid crystal cell molecules 106 and 108, which have no strength for a period of time, may be in an undefined state.

If the CPU 114 of the 3D glasses 104 detects an activation of the 3D glasses 1102, then the CPU applies alternating voltage signals 1104a and 1104b to the shutters 106 and 108 respectively at 1104. In an exemplary embodiment, the The voltage applied to the shutters 106 and 108 is alternated between positive and negative peak values to avoid ionization problems in the shutter liquid crystal cells. In an exemplary embodiment, the voltage signals 1104a and 1104b are at least partially out of phase with each other. Alternatively, voltage signals 1104a and 1104b may be in phase or completely out of phase. In one exemplary embodiment, one or both voltage signals 1104a and 1104b may be alternated between a zero voltage and a peak voltage. In one exemplary embodiment, other forms of voltage signals may be applied to the shutters 106 and 108 such that the liquid crystal cells of the shutters are brought into a definite operating state. In an exemplary embodiment, applying the voltage signals 1104a and 1104b to the shutters 106 and 108 causes the shutters to open and close, either at the same time or at different times. Alternatively, applying the voltage signals 1104a and 1104b causes the shutters 106 and 108 to remain closed at all times.

While applying voltage signals 1104a and 1104b to shutters 106 and 108, CPU 114 checks for a warm-up timeout at 1106. If CPU 114 detects a warm-up timeout at 1106, then the CPU will stop applying voltage signals 1104a and 1104b to the shutters 106 and 108 at 1108.

In an exemplary embodiment, at 1104 and 1106, CPU 114 applies voltage signals 1104a and 1104b to shutters 106 and 108 for a period of time sufficient to drive the shutter liquid crystal cells. In an exemplary embodiment, CPU 114 applies voltage signals 1104a and 1104b to shutters 106 and 108 for a timeout period of two sequels. In an exemplary embodiment, the maximum magnitude of the voltage signals 1104a and 1104b may be 14 volts. In an exemplary embodiment, the timeout period at 1106 may be two seconds. In an exemplary embodiment, the maximum magnitude of voltage signals 1104a and 1104b may be greater than or less than 14 volts and the timeout period may be longer or shorter. In an exemplary embodiment, during method 1100, the CPU 114 may open and close the shutters 106 and 108 at a different frequency from that which would be used to watch a movie. In an exemplary embodiment, in 1104, the voltage signals 1104a and 1104b applied to shutters 106 and 108 alternate at a different frequency from that which would be used to watch a movie. In an exemplary embodiment, in 1104, the voltage signals applied to the shutters 106 and 108 do not alternate and are constantly applied over the heating time period and therefore the shutter liquid crystal cells may remain opaque. throughout the warm-up period. In an exemplary embodiment, the heating method 1100 may occur with or without the presence of a synchronization signal. Thus, method 1100 provides an operation HEATING mode for the 3D glasses 104. In an exemplary embodiment, after the implementation of the heating method 1100, the 3D glasses are placed in a NORMAL EXECUTE mode of operation and can then be implement method 200. Alternatively, in an exemplary embodiment, after implementation of the heating method 1100, the 3D glasses are placed in a TRANSPARENT mode of operation and may then implement method 1300, described below.

Referring now to Figs. 13 and 14, in an exemplary embodiment, during operation of system 100, the 3D glasses 104 implement a method of operation 1300 wherein, at 1302, the CPU 114 checks for the synchronization signal. detected by signal sensor 112 is valid or invalid. If the CPU 114 determines that the synchronization signal is invalid at 1302, then the CPU applies voltage signals 1304a and 1304b to the shutters 106 and 108 of the 3D glasses 104 at 1304. In an exemplary embodiment, the voltage applied to the shutters 106 and 108 is alternated between positive and negative peak values to avoid ionization problems in the shutter liquid crystal cells. In one exemplary embodiment, one or both voltage signals 1104a and 1104b may be alternated between a zero voltage and a peak voltage. In one exemplary embodiment, other forms of voltage signals may be applied to the shutters 106 and 108 such that the liquid crystal cells of the shutters remain open so that the wearer of the 3D glasses 104 can normally see through the shutters. res. In an exemplary embodiment, applying the voltage signals 1104a and 1104b to the shutters 106 and 108 causes the shutters to open.

During the application of voltage signals 1304a and 1304b on shutters 106 and 108, CPU 114 checks for a transparency timeout at 1306. If CPU 114 detects a transparency timeout at 1306, then the CPU will stop applying voltage signals 1304a and 1304b to shutters 106 and 108 in 1308. Thus, in an exemplary embodiment,

if the 3D glasses 104 do not detect a valid synchronization signal, they may enter a transparent mode of operation and implement method 1300. In the transparent mode of operation, in an exemplary embodiment, both shutters 106 and 108 of the 3D glasses 104 remain open so that the viewer can see normally through the shutters of the 3D glasses. In an exemplary embodiment, a constant voltage is applied, alternating between positive and negative, to keep the liquid crystal shutter cells 106 and 108 of the 3D glasses in a transparent state. The constant voltage could, for example, be in the range of 2 to 3 volts, but the constant voltage could be any other voltage suitable to keep the shutters reasonably transparent. In an exemplary embodiment, shutters 106 and 108 of 3D glasses 104 may remain transparent until the 3D glasses can validate a coding signal. In an exemplary embodiment, the shutters 106 and 108 of the 3D glasses may alternately open and close at a frequency that allows the wearer of the 3D glasses to see normally.

Thus, method 1300 provides a method of making the operation of the 3D glasses 104 transparent and thereby providing a TRANSPARENT mode of operation.

Referring now to Fig. 15, in an exemplary embodiment, during operation of system 100, the 3D glasses 104 implement a battery monitoring method 1500 in which, in 1502, the 3D glasses CPU 114 uses the battery sensor 122 to determine the remaining battery life. If the 3D glasses CPU 114 determines that the remaining battery life 120 is not adequate at 1502, then the CPU provides an indication of a low battery charge status at 1504.

In an exemplary embodiment, an improper remaining battery life may, for example, be any period of less than 3 hours. In one exemplary embodiment, a suitable remaining battery life may be prefixed by the 3D glasses manufacturer and / or programmed by the 3D glasses user.

In an exemplary embodiment at 1504, the 3D glasses CPU 114 will indicate a low battery charge status by causing the 3D glasses shutters 106 and 108 to flash slowly while causing the shutters to flash simultaneously at a moderate frequency that is visible to the wearer of the 3D glasses, flashing an indicator light, generating a beep, and the like.

In an exemplary embodiment, if the 3D glasses CPU 114 detects that the remaining battery life is insufficient to last for a specific period of time, then the 3D glasses CPU will indicate low battery charge status at 1504 and it will then prevent the user from activating the 3D glasses.

In an exemplary embodiment, the CPU 114 of the 3D glasses 104 determines whether or not the remaining battery life is adequate each time the 3D glasses change to TRANSPARENT mode of operation.

In an exemplary embodiment, if the 3D glasses CPU 114 determines that the battery will last for the appropriate amount of preset time, at least then the 3D glasses will continue to operate normally. Normal operation may include maintaining TRANSPARENT MODE of operation for five minutes while checking a valid signal from signal transmitter 110 and then switching to OFF mode, where 3D glasses 104 periodically activate to check for any signal from the transmitter. signal transmitter.

In an exemplary embodiment, the CPU 114 of the 3D glasses 104 checks for low battery status shortly before turning off the 3D glasses. In an exemplary embodiment, if the battery 120 does not last for the appropriate preset remaining life, then the shutters 106 and 108 will start to flash slowly.

In an exemplary embodiment, if the battery 120 will not last for the appropriate predefined remaining life, the shutters 106 and / or 108 are placed in an opaque status, ie the liquid crystal cells are closed by two seconds and then placed in the transparent condition, that is, the liquid crystal cells are opened for 1/10 ° of a second. The length of time the shutters 106 and / or 108 are closed and open can be any length of time.

In an exemplary embodiment, the 3D glasses 104 can check for low battery status at any time, including during warm-up, normal operation, transparent mode, off mode, or the transition between any condition. In an exemplary embodiment, if a low battery charge status is detected at the time the viewer is likely to be in the middle of a movie, the 3D glasses 104 may not immediately indicate the low battery condition.

In some embodiments, if the 3D glasses CPU 104 detects a low battery level, the user will not be able to turn on the 3D glasses.

In an exemplary embodiment, the verifier 1600 includes a signal transmitter 1600a for transmitting verification signals 1600b to the signal sensor 112 of the 3D glasses. In an exemplary embodiment, check signal 1600b may include a synchronization signal having a low frequency to cause shutters 106 and 108 of the 3D glasses 104 to flash at a low frequency that is visible to the wearer of the 3D glasses. . In an exemplary embodiment, a failure of shutters 106 and 108 to flash in response to check signal 1600b may indicate a failure by 3D glasses 104 to operate properly. Referring now to Fig. 17, in an exemplary embodiment, the 3D glasses 104 further include a charge pump 1700 operably coupled to the CPU 114, the shutter controllers 116 and 118, the battery 120 for converting the battery output voltage to a higher output voltage for use in operating the shutter controllers.

In an exemplary embodiment, the magnitude of the high voltage applied to the Left shutter 1802 at 2106 is 15 volts. In an exemplary embodiment, the magnitude of the capture voltage applied at right shutter 1804 at 2106 is 2 volts. In an exemplary embodiment, the capture voltage is applied to the right shutter 1804 at 2106 by controlling the operating state of the control signal D, which may be low, high or open, to be opened and thereby enable operation of the voltage splitter and RIO components, and keeping the control signal E in a high state. In an exemplary embodiment, applying the capture voltage 2106 to the right shutter 1804 is delayed for a predefined time period to allow faster rotation of the molecules within the right shutter liquid crystals during the predefined time period. Subsequent application of the capture voltage, after the predefined period of time has elapsed, then prevents molecules within the liquid crystals in right shutter 1804 from spinning too far during opening of the right shutter.

Alternatively, if at 2104 CPU 1820 determines that the received sync signal indicates that left shutter 1802 should be opened and right shutter 1804 should be closed, then the CPU transmits control signals A, B, C, D. and E to the left and right shutter controllers 1806 and 1808 at 2108 to apply a high voltage on the right shutter 1804 and no voltage followed by a small capture voltage on the left shutter 1802. In an exemplary embodiment, the magnitude The high voltage applied on the right shutter 1804 at 2108 is 15 volts. In an exemplary embodiment, the magnitude of the capture voltage applied at left shutter 1802 at 2108 is 2 volts. In an exemplary embodiment, the capture voltage is applied to the left shutter 1802 at 2108 by controlling the control signal D to be opened and thereby allowing operation of the voltage and RIO splitter components, and maintaining the control signal E at a high level. In one exemplary embodiment, applying the capture voltage 2108 on the left shutter 1802 is delayed for a predefined time period to allow faster rotation of the molecules within the left shutter liquid crystals during the predefined time period. Subsequent application of the capture voltage, after the preset time period has elapsed, then prevents molecules within the liquid crystals in the left shutter 1802 from spinning too far during the left shutter opening.

In an exemplary embodiment, during method 2100, the stresses applied to the left and right shutters 1802 and 1804 are alternately positive and negative in subsequent repeats of steps 2106 and 2108 to prevent damage to the shutter liquid crystal cells. left and right. Thus method 2100 provides a MODE of

NORMAL or RUN operation for the 1800 3D glasses.

Referring now to Figs. 23 and 24, in an exemplary embodiment, during the operation of the 3D glasses 1800, the 3D glasses implement a method of heating the operation 2300 wherein the control signals A, B, C, D and E generated by CPU 1810 are used to control the operation of the left and right shutter controllers 1806 and 1808, so that they in turn control the operation of the left and right shutter 1802 and 1804.

At 2302, the 3D glasses CPU 1810 checks for power on the 3D glasses. In an exemplary embodiment, the 1810 3D glasses can be turned on by a user by activating an activation switch or by an automatic activation sequence. Upon activation of the 1810 3D glasses, the shutters 1802 and 1804 of the 3D glasses may, for example, require a warm-up sequence. The shutter liquid crystal cells 1802 and 1804, which have no strength for a period of time, may be in an undefined state.

If the 3D glasses CPU 1810 1800 detects an activation of the 3D glasses at 2302, then the CPU applies alternating voltage signals 2304a and 2304b to the left and right shutters 1802 and 1804 respectively at 2304. In one embodiment For example, the voltage applied to the left and right shutters, 1802 and 1804, alternates between positive and negative peak values to avoid ionization problems in the liquid crystal shutter cells. In an exemplary embodiment, voltage signals 2304a and 2304b may be at least partially out of phase with each other. In one exemplary embodiment, one or both voltage signals 2304a and 2304b may be alternated between a zero voltage and a peak voltage. In an exemplary embodiment, other forms of voltage signals may be applied to the left and right shutters 1802 and 1804 such that the liquid crystal cells of the shutters are brought into a definite operating state. In an exemplary embodiment, applying the voltage signals 2304a and 2304b to the left and right shutters 1802 and 1804 causes the shutters to open and close, either at the same time or at different times. Alternatively, applying the voltage signals 2304a and 2304b may cause the left and right shutters 1802 and 1804 to remain closed.

During the application of voltage signals, 2304a and

2304b, on the left and right shutters 1802 and 1804, CPU 1810 checks for a warm-up timeout at 2306. If CPU 1810 detects a warm-up timeout at 2306, then the CPU will stop applying the voltage signals. , 2304a and 2304b, on the left and right shutters, 1802 and 1804, in 2308.

In an exemplary embodiment, at 2304 and 2306, CPU 1810 applies voltage signals 2304a and 2304b to left and right shutters 1802 and 1804 for a period of time sufficient to drive the liquid crystal cells of the shutters. . In an exemplary embodiment, CPU 1810 applies voltage signals 2304a and 2304b to the left and right shutters 1802 and 1804 for a period of two seconds. In an exemplary embodiment, the maximum magnitude of the voltage signals 2304a and 2304b may be 15 volts. In an exemplary embodiment, the timeout period at 2306 may be two seconds. In an exemplary embodiment, the maximum magnitude of voltage signals 2304a and 2304b may be greater than or less than 15 volts, and the timeout period may be longer or shorter. In an exemplary embodiment, during method 2300, CPU 1810 may open and close left and right shutters 1802 and 1804 at a different frequency than that which would be used to watch a movie. In one exemplary embodiment, at 2304, the voltage signals applied to the left and right shutters 1802 and 1804 do not alternate and are constantly applied over the heating time period and therefore the liquid crystal cells of the shutters. may remain opaque throughout the warm-up period. In an exemplary embodiment, heating method 2300 may occur with or without the presence of a synchronization signal. Thus, method 2300 provides an operation HEAT mode for the 1800 3D glasses. In an exemplary embodiment, after the implementation of the 2300 warm-up method, the 1800 3D glasses are placed in a NORMAL EXECUTE mode of operation and can then implement method 2100. Alternatively, in an exemplary embodiment, after implementing heating method 2300, the 3 D 1800 glasses are placed in a TRANSPARENT mode of operation and may then implement method 2500, described below.

Referring now to Figs. 25 and 26, in an exemplary embodiment, during operation of the 3D glasses 1800, the 3D glasses implement a 2500 method of operation wherein the control signals A, B, C, D and E CPU 1810 are used to control the operation of the left and right shutter controllers 1806 and 1808 so that they in turn control the operation of the left and right shutter 1802 and 1804 as a function of the synchronization signal received by the signal sensor 1814. At 2502, CPU 1810 checks to see if the signal from

synchronization detected by signal sensor 1814 is valid or invalid. If CPU 1810 determines that the synchronization signal is invalid at 2502, then the CPU applies voltage signals 2504a and 2504b to the left and right shutters 1802 and 1804 of the 1800 to 2504 3D glasses. In an exemplary embodiment The applied voltage, 2504a and 2504b, on the left and right shutters, 1802 and 1804, alternates between positive and negative peak values to avoid ionization problems in the liquid crystal cells of the shutter. In one exemplary embodiment, one or both voltage signals 2504a and 2504b may be alternated between a zero voltage and a peak voltage. In an exemplary embodiment, other forms of voltage signals may be applied to the left and right shutters 1802 and 1804 such that the liquid crystal cells of the shutters remain open so that the wearer of the 3D glasses 1800 can normally see. through the shutters. In an exemplary embodiment, applying the voltage signals 2504a and 2504b to the left and right shutters 1802 and 1804 causes the shutters to open.

When applying voltage signals 2504a and 2504b to the left and right shutters 1802 and 1804, CPU 1810 checks for a transparency timeout at 2506. If CPU 1810 detects a transparency timeout at 2506, then CPU 1810 will stop applying voltage signals 2504a and 2504b to shutters 1802 and 1804 at 2508.

Thus, in an exemplary embodiment, if the 3D glasses 1800 do not detect a valid sync signal, they can enter a transparent mode of operation and implement method 2500. In the transparent mode of operation, in an exemplary embodiment Both the 1802 and 1804 shutters of the 1800 3D glasses remain open so that the viewer can normally see through the shutters of the 3D glasses. In an exemplary embodiment, a constant voltage is applied, alternating between positive and negative, to keep the shutter liquid crystal cells, 1802 and 1804, of the 3D glasses 1800 in a transparent state. The constant voltage could, for example, be in the range of 2 to 3 volts, but the constant voltage could be any other voltage suitable to keep the shutters reasonably transparent. In an exemplary embodiment, the shutters 1802 and 1804 of the 3D glasses 1800 may remain transparent until the 3D glasses can validate a coding signal and / or until a time-out transparently. In an exemplary embodiment, the shutters 1802 and 1804 of the 3D glasses 1800 may remain transparent until the 3D glasses are able to validate a coding signal and may then implement method 2100 and / or if a timeout occurs in 2506, then may implement method 900. In an exemplary embodiment, shutters 1802 and 1804 of 1800 3D glasses may alternately open and close at a frequency that allows the wearer of the 3D glasses to view normally.

Thus, the 2500 method provides a method of making the operation of the 3D 1800 glasses transparent and thereby providing a TRANSPARENT mode of operation. Now, with reference to Figs 27 and 28, in a way

In an exemplary embodiment, during the operation of the 3D glasses 1800, the 3D glasses implement a battery monitoring method 2700 120 wherein the control signals A, B, C, D, and E generated by CPU 1810 are used to control the operation of the left and right shutter controllers, 1806 and 1808, so that they, in turn, control the operation of the left and right shutters, 1802 and 1804, depending on the condition of battery 120, as detected by battery sensor 1812. On 2702, 1810 CPU of the 3D glasses uses the sensor of the

1812 battery to determine the remaining battery life of 120 battery. If the 1810 3D glasses CPU 1810 determines that the remaining battery life of 120 is not adequate at 2702, then the CPU provides an indication of a low battery charge status at 2704.

In an exemplary embodiment, an improper remaining battery life may, for example, be any period of less than 3 hours. In an exemplary embodiment, a suitable remaining battery life may be preset by the manufacturer of the 3D glasses 1800 and / or user programmed by the 3D glasses.

In an exemplary embodiment, on 2704, the 3D glasses CPU 1810 1800 will indicate a low battery charge status by causing the 3D glasses' left and right shutters 1802 and 1804 to blink slowly, causing the 3D glasses to shutters flash simultaneously at a moderate frequency that is visible to the wearer of the 3D glasses, flashing an indicator light, generating a beep, and the like.

In an exemplary embodiment, if the 1800 3D glasses CPU 1810 detects that the remaining battery life is insufficient to last for a specific period of time, then the 3D glasses CPU will indicate the low battery charge status at 2704 and it will then prevent the user from activating the 3D glasses.

In an exemplary embodiment, the 3D glasses CPU 1810 1800 determines whether or not the remaining battery life is adequate each time the 3D glasses switch to OFF mode and / or TRANSPARENT mode of operation.

In an exemplary embodiment, if the 1810 3D glasses CPU 1810 determines that the battery will last for the appropriate amount of preset time, at least then the 3D glasses will continue to operate normally. Normal operation could, for example, include keeping the TRANSPARENT MODE of operation for five minutes while checking a valid signal from signal transmitter 110 and then switching to a OFF mode or on mode, where the 3D glasses 1810 periodically activate to check for any signal from the signal transmitter.

In an exemplary embodiment, the 3D glasses CPU 1810 1800 checks for low battery status just before turning off the 3D glasses. In an exemplary embodiment, if the battery 120 does not last for the appropriate preset remaining life, then the shutters 1802 and 1804 will start to flash slowly. In an exemplary embodiment, if the battery

120 will not last for the appropriate preset remaining life, the shutters 1802 and / or 1804 are placed in an opaque status, ie the liquid crystal cells are closed for two seconds and then placed in the transparent condition, or that is, the liquid crystal cells are opened for 1/10 ° of a second. The length of time that the shutters 1802 and / or 1804 are closed and opened can be any length of time. In an exemplary embodiment, the flashing of the shutters 1802 and 1804 is synchronized with the power supply to signal sensor 1814 to allow the signal sensor to check for any signal from signal transmitter 110.

In an exemplary embodiment, the 1800 3D glasses can check for low battery status at any time, including during warm-up, during normal operation, during transparent mode, during off mode, or in the transition between any condition. In an exemplary embodiment, if a low battery charge status is detected at a time when the viewer is probably in the middle of a movie, the 3D 1800 glasses may not immediately indicate the low battery condition. In some embodiments, if the 1800 3D glasses CPU 1810 detects a low battery level, the user will not be able to turn on the 3D glasses.

Now, with reference to Fig. 29, in an exemplary embodiment, during the operation of the 3D glasses 1800, the 3D glasses implement a method for turning off the 3D glasses wherein the control signals A, B, C, D and E generated by CPU 1810 are used to control the operation of the left and right shutter controllers 1806 and 1808 so that they in turn control the operation of the left and right shutters 1802 and 1804 depending on the condition of the battery 120 as detected by the 1812 battery sensor. In particular, if the user of the 1800 3D glasses selects to turn off the 3D glasses or the 1810 CPU selects to turn off the 3D glasses, then the voltage applied to the left and right shutters 1802 and 1804 of the 3D glasses is both set at zero.

In an exemplary embodiment, the CPU 3012 U2 microcontroller is a programmable microcontroller model number PIC16F636, commercially available from Microchip.

In an exemplary embodiment, the signal sensor 3014 includes a photodiode D3 for sensing the transmission of signals, including the synchronization signal and / or configuration data, by the signal transmitter 110. In an exemplary embodiment, the photodiode D3 is a model BP104FS photodiode, commercially available from Osram. In an exemplary embodiment, signal sensor 3014 further includes operational amplifiers, U5-1, U5-2 and U3, and relative signal conditioning components, resistors R2, R3, R5, R7, R8, R9, RIO, R11, R12 and R13, capacitors Cl, Cl and C9, and schottky diodes, D1 and D5, which may, for example, condition the signal by preventing the cutting of the felt signal by controlling the gain.

In an exemplary embodiment, the charge pump 3016 amplifies the magnitude of battery output voltage 120 using a charge pump from 3V to -12V. In an exemplary embodiment, the charge pump 3016 includes a MOSFET Q1, a schottky D6 diode, a Li inductor, and a zener diode D7. In an exemplary embodiment, the charge pump output signal 3016 is provided in the form of input signals for input / output switch signals X1 and Y1 of analog and digitally controlled switch U4 of common shutter controller 3010 and in VEE input voltage form for the analog and digitally controlled switches Ul, U6 and U4 of the left shutter controller 3006, right shutter controller 3008, and common shutter controller 3010. In one exemplary embodiment, the supply

The voltage range includes a transistor Q2, a capacitor C5, and resistors R1 and R16. In an exemplary embodiment, the voltage supply provides IR signal as an input signal to the analog and digitally controlled switch input input / output signal Z1 of the common shutter controller 3010. In an exemplary embodiment, The voltage supply provides a ground interrupt switch.

As shown in Fig. 32, in an exemplary embodiment, during operation of the 3D glasses 3000, the analog and digitally controlled switches Ul, U6 and U4 under the control signals A, B, C, D, CPU 3012 E, F and G can provide various voltages on one or both of the left and right shutters 3002 and 3004. In particular, the analog and digitally controlled switches Ul, U6 and U4 under control of control signals A , B, C, D, E, F and G of CPU 3012, can provide: 1) a positive or negative voltage of 15 volts on one or both of the left and right shutters, 3002 and 3004, 2) a positive or negative voltage. about 2 volts on one or both left and right shutters, 3) a positive or negative voltage of about 3 volts on one or both left and right shutters, or 4) provide 0 volts , ie a neutral state in one or both of the left and right shutters.

In an exemplary embodiment, as illustrated in Fig. 32, control signal A controls left shutter operation 3002 and control signal B controls right shutter operation 3004 by controlling switch operation within analog switches and digitally controlled, Ul and U6, respectively, which generate XeY output signals that are applied to the left and right shutters. In one exemplary embodiment, the control inputs A and B of each of the analog and digitally controlled switches Ul and U6 are connected together so that the exchange between two input signal pairs occurs simultaneously and the selected inputs are routed to terminals. left and right shutters, 3002 and 3004. In an exemplary embodiment, the CPU 3012 control signal A controls the first two switches on the analog and digitally controlled switch Ul and the CPU control signal B controls the first two switches. on the analog and digitally controlled switch U6.

In an exemplary embodiment, as illustrated in Fig. 32, one of the terminals of each of the left and right shutters, 3002 and 3004, is always connected to 3V. Thus, in an exemplary embodiment, the analog, digitally controlled switches Ul, U6, and U4 under the control of CPU 3012 control signals A, B, C, D, E, F, and G are operated to bring -12V, 3V, IR or OV to the other left and right shutter terminals, 3002 and 3004. As a result, in an exemplary embodiment, the analog, digitally controlled switches Ul, U6 and U4 under control of the control signals CPU 3012 A, B, C, D, E, F and G are operated to generate a potential difference of 15V, 0V, 2V or 3V at the left and right shutter terminals, 3002 and 3004.

In an exemplary embodiment, the third

Analog and digitally controlled switch switch U6 is not used and all terminals for the third switch are grounded. In an exemplary embodiment, the third switch of the analog and digitally controlled switch Ul is used to save energy.

In particular, in an exemplary embodiment, as illustrated in Fig. 32, control signal C controls the operation of the switch within analog and digitally controlled switch Ul which generates output signal Z. As a result, when signal Control C is a high digital value, the INH input signal for the analog and digitally controlled switch U4 is also a high digital value, causing all output channels of the analog and digitally controlled switch U4 to be turned off. As a result, when the control signal C is a high digital value, the left and right shutters, 3002 and 3004, are shorted and thus allow half the load to be transferred between the shutters, thus saving energy and extending Battery life 120.

In an exemplary embodiment, by using the control signal C to short the left and right shutters 3002 and 3004, the high amount of charge collected on a shutter that is in the closed state can be used to partially charge the shutter. another shutter just before it enters the closed state, thus saving the amount of charge that would have to be provided entirely by battery 120.

In an exemplary embodiment, when the control signal C generated by CPU 3012 is a high digital value, for example, the negatively charged card,

12V, left shutter 3002, then in a closed state and having a potential difference of 15V there, is connected to the most negatively charged plate of the right shutter 3004, then in an open state and still charged to + IV and having a potential difference of 2V over there. In an exemplary embodiment, the positively charged plates on both shutters 3002 and 3004 will be charged to + 3V. In an exemplary embodiment, the control signal C generated by CPU 3012 shifts to a high digital value for a short time near the end of the left shutter closed state 3002 and shortly before the right shutter closed state 3004. When The control signal C generated by CPU 3012 is a high digital value, the INH inhibit terminal on the analog and digitally controlled switch U4 is also a high digital value. As a result, in one exemplary embodiment, all output channels X, Y and Z of U4 are in the off state. This allows the load stored on the left and right shutter plates 3002 and 3004 to be distributed between the shutters so that the potential difference in both shutters is approximately 17 / 2V or 8.5V. As a shutter terminal, 3002 and 3004, is always connected to 3V, the negative shutter terminals, 3002 and 3004, are then at -5.5V. In an exemplary embodiment, the control signal C generated by CPU 3012 then shifts to a low digital value and thus disconnects the negative terminals of the shutters 3002 and 3004 from each other. Then, in an exemplary embodiment, the closed state for the right shutter 3004 starts and battery 120 still charges the negative right shutter terminal when operating the analog and digitally controlled switch U4 to -12V. As a result, in an exemplary experimental embodiment, approximately 40% energy savings were achieved during a normal RUN mode of operation, as described below with respect to method 3300, of the 3D 3000 glasses. In one exemplary embodiment, the sign of

CPU 3012-generated C control is provided in the form of a short pulse that changes from top to bottom when the CPU-generated A or B control signals change from high to low or low to high to begin next left shutter aperture / right shutter closure or right shutter aperture / left shutter closure.

Referring now to Figs. 33 and 34, in one exemplary embodiment, during operation of the 3D glasses 3000, the 3D glasses perform a normal RUN mode of operation 3300 wherein the control signals A, B, C, D , E, F, and G generated by CPU 3012 are used to control the operation of the left and right shutter controllers 3006 and 3008, and the central shutter controller 3010 so that they control the operation of the left and right shutters. 3002 and 3004, depending on the type of synchronization signal detected by signal sensor 3014.

In particular, at 3302, if CPU 3012 determines that signal sensor 3014 has received a synchronization signal, then at 3304, the control signals A, B, C, D, E, F and G generated by CPU 3012 are used to control the operation of the left and right shutter controllers 3006 and 3008 and the central shutter controller 3010 to transfer load between the left and right shutters 3002 and 3004 as described above with respect to Fig. 32.

In an exemplary embodiment, in 3304, the

Control signal C generated by CPU 3012 is set at a high digital value to approximately 0.2 milliseconds to short circuit the left and right shutter terminals 3002 and 3004, thereby transferring load between the left and right shutters. In an exemplary embodiment, at 3304, the control signal C generated by CPU 3012 is set at a high digital value to approximately 0.2 milliseconds, thereby shorting the most negatively charged terminals of the left and right shutters, 3002. and 3004, and thus transfer charge between the left and right shutters. Thus, control signal C is provided in the form of a short pulse that passes from high to low when, or earlier, control signals A or B change from high to low or from low to high. As a result, energy savings occur during operation of the 3D 3000 glasses during the cycle of switching between left open / right closed and left closed / right open shutters.

CPU 3012 then determines the signal type of

synchronization received at 3306. In an exemplary embodiment, a synchronization signal including 2 pulses indicates that left shutter 3002 should be opened and right shutter 3004 should be closed, while a synchronization signal including 3 pulses indicates that the right shutter should be opened and the left shutter should be closed. In one exemplary embodiment, other different numbers and formats of synchronization signals may be used to control the alternating opening and closing of the left and right shutters 3002 and 3004.

If, at 3306, CPU 3012 determines that the received synchronization signal indicates that left shutter 3002 should be opened and right shutter 3004 closed, then the CPU transmits control signals A, B, C, D, E, F and G to the left and right shutter controllers, 3006 and 3008, and the common shutter controller 3010, to apply a high voltage to the right shutter 3004 and no voltage followed by a small capture voltage on the left shutter 3002. In an exemplary embodiment, the magnitude of the high voltage applied to the right shutter 3004 at 3308 is 15 volts. In an exemplary embodiment, the magnitude of the capture voltage applied to the left shutter 3002 at 3308 is 2 volts. In an exemplary embodiment, the capture voltage is applied to the left shutter 3002 at 3308 by controlling the operating state of the control signal D to be low and the operating state of the control signal F, which may be low or high at be tall. In an exemplary embodiment, the application of the capture voltage 3308 on the left plug 3002 is delayed for a predefined period of time to allow faster rotation of the molecules within the left plug liquid crystals. Subsequent application of the capture voltage, after the predefined period of time has elapsed, prevents molecules within the liquid crystals in the left shutter 3002 from spinning too far during opening of the left shutter. In an exemplary embodiment, applying the capture voltage at 3308 to the left shutter 3002 is delayed by about 1 millisecond. Alternatively, if, at 3306, CPU 3012 determines that the received sync signal indicates that left shutter 3002 should be closed and right shutter 3004 should be opened, then the CPU transmits control signals A, B, C, D, E, F and G to the left and right shutter controllers 3006 and 3008, and the common shutter controller 3010 at 3310 to apply a high voltage on the left shutter 3002 and no voltage followed by a small capture voltage on the right shutter. 3004. In an exemplary embodiment, the magnitude of the high voltage applied to the left shutter 3002 at 3310 is 15 volts. In an exemplary embodiment, the magnitude of the capture voltage applied to the right shutter 3004 at 3310 is 2 volts. In an exemplary embodiment, the capture voltage is applied to the right shutter 3004 at 3310 by controlling the control signal F to be high and the control signal G to be low. In an exemplary embodiment, the application of the capture voltage 3310 on the right shutter 3004 is delayed for a predefined period of time to allow faster rotation of the molecules within the right shutter liquid crystals. Subsequent application of the capture voltage, after the predefined period of time has elapsed, prevents molecules within the liquid crystals in right shutter 3004 from spinning too far during opening of the right shutter. In an exemplary embodiment, the application of the capture voltage at 3310 on right shutter 3004 is delayed by about 1 millisecond. In an exemplary embodiment, during the

In method 3300, the voltages applied to the left and right obturators 3002 and 3004 are alternately positive and negative in subsequent repeats of steps 3308 and 3310 to prevent damage to the left and right obturator liquid crystal cells.

Thus, the 3300 method provides a NORMAL or RUN mode of operation for the 3D 3000 glasses.

Now, with reference to Figs. 35 and 36, in a form

In an exemplary embodiment, during the operation of the 3D glasses 3000, the 3D glasses implement an operation heating method 3500 wherein the control signals A, B, C, D, E, F and G generated by the CPU 3012 are used to control the operation of the left and right shutter controllers 3006 and 3008, and the central shutter controller 3010 to control the operation of the left and right shutter 3002 and 3004 in turn.

At 3502, the 3D glasses CPU 3012 checks for power on the 3D glasses. In an exemplary embodiment, the 3D glasses 3000 may be turned on by a user by activating an activation switch or an automatic activation sequence, and / or by the signal sensor 3014 sensing a valid synchronization signal. When activating the 3D glasses 3000, the shutters 3002 and 3004 of the 3D glasses may, for example, require a warm-up sequence. The shutter liquid crystal cells 3002 and 3004, which have no strength for a period of time, may be in an undefined state. If the CPU 3012 of the 3D 3000 glasses detects a

activation of the 3D glasses at 3502, then the CPU applies alternating voltage signals to the left and right shutters 3002 and 3004 respectively at 3504. In an exemplary embodiment, the voltage applied to the left and right shutters 3002 and 3004, is switched between positive and negative peak values to avoid ionization problems in the shutter liquid crystal cells. In an exemplary embodiment, the voltage signals applied to the left and right shutters 3002 and 3004 may be at least partially out of phase with each other. In one exemplary embodiment, one or both of the voltage signals applied to the left and right shutters 3002 and 3004 may be alternated between a zero voltage and a peak voltage. In one exemplary embodiment, other forms of voltage signals may be applied to the left and right shutters 3002 and 3004 such that the liquid crystal cells of the shutters are brought into a definite operating state. In an exemplary embodiment, applying the voltage signals to the left and right shutters 3002 and 3004 causes the shutters to open and close, either at the same time or at different times. During the application of voltage signals in the

left and right shutters 3002 and 3004, CPU 3012 checks for a warm-up timeout at 3506. If CPU 3012 detects a warm-up timeout at 3506, then the CPU will stop applying voltage signals to the left shutters. and right, 3002 and 3004, at 3508.

In an exemplary embodiment at 3504 and 3506, CPU 3012 applies the voltage signals to the left and right shutters 3002 and 3004 for a period of time sufficient to drive the liquid crystal cells of the shutters. In an exemplary embodiment, CPU 3012 applies voltage signals to the left and right shutters 3002 and 3004 for a period of two seconds. In an exemplary embodiment, the maximum magnitude of the voltage signals applied to the left and right shutters 3002 and 3004 may be 15 volts. In an exemplary embodiment, the timeout period at 3506 may be two seconds. In an exemplary embodiment, the maximum magnitude of the voltage signals applied to the left and right shutters, 3002 and 3004, may be greater than or less than 15 volts, and the timeout period may be longer or shorter. In an exemplary embodiment, during method 3500, the CPU 3012 may open and close the left and right shutters 3002 and 3004 at a different frequency than that which would be used to watch a movie. In an exemplary embodiment at 3504, the voltage signals applied to the left and right shutters, 3002 and 3004, do not alternate and are constantly applied over the heating time period and therefore the liquid crystal cells of the shutters. may remain opaque throughout the warm-up period. In an exemplary embodiment, the heating method 3500 may occur with or without the presence of a synchronization signal. Thus, method 3500 provides an operation HEAT mode for the 3D 3000 glasses. In an exemplary embodiment, after the implementation of the 3500 warm-up method, the 3D 3000 glasses are placed in a NORMAL MODE, RUN MODE, or MODE. TRANSPARENT operation and can then implement method 3300.

Referring now to Figs. 37 and 38, in an exemplary embodiment, during the operation of the 3D glasses 3000, the 3D glasses implement a method 3700 of operation wherein the control signals A, B, C, D, E , F and G generated by CPU 3012 are used to control the operation of the left and right shutter controllers, 3006 and 3008, and the common shutter controller 3010, to in turn control the operation of the left and right shutters, 3002 and 3004, depending on the synchronization signal received by signal sensor 3014.

At 3702, CPU 3012 checks whether the synchronization signal detected by signal sensor 3014 is valid or invalid. If CPU 1810 determines that the synchronization signal is invalid at 3702, then the CPU applies voltage signals to the left and right shutters 3002 and 3004 of the 3D glasses 3000 at 3704. In an exemplary embodiment, the voltage applied to the Left and right shutters, 3002 and 3004, alternate between positive and negative peak values to avoid ionization problems in the liquid crystal shutter cells. In an exemplary embodiment, the voltage applied to the left and right shutters 3002 and 3004 at 3704 is alternated between positive and negative peak values to provide a square wave signal having a frequency of 60 Hz. In an exemplary embodiment, the square wave signal alternates between + 3V and -3V. In one exemplary embodiment, one or both of the voltage signals applied to the left and right shutters 3002 and 3004 at 3704 may be alternated between zero voltage and a peak voltage. In one exemplary embodiment, other forms, including other frequencies, of voltage signals may be applied to the left and right shutters 3002 and 3004 such that the liquid crystal cells of the shutters remain open for the spectacle wearer to wear. 3D 3000 can normally see through the shutters. In an exemplary embodiment, applying the voltage signals to the left and right shutters 3002 and 3004 at 3704 causes the shutters to open.

When applying voltage signals to the left and right shutters 3002 and 3004 at 3704, CPU 3012 checks for a transparency timeout at 3706. If CPU 3012 detects a transparency timeout at 3706, then the CPU 3012 will cease to apply the voltage signals to shutters 3002 and 3004 at 3708 which can then place the 3D 3000 glasses in an OFF mode of operation. In one exemplary embodiment, the timeout duration for transparency may, for example, be up to 4 hours long.

Thus, in an exemplary embodiment, if the 3D glasses 3000 do not detect a valid synchronization signal, they can enter a transparent mode of operation and implement method 3700. In the transparent mode of operation, in an exemplary embodiment , both the 3002 and 3004 shutters of the 3D glasses 3000 remain open so that the viewer can normally see through the shutters of the 3D glasses. In one exemplary embodiment, a constant voltage is applied, alternating between positive and negative, to keep the liquid crystal shutter cells 3002 and 3004 of the 3D glasses 3000 in a transparent state. The constant voltage could, for example, be 2 volts, but the constant voltage could be any other voltage suitable to keep the shutters reasonably transparent. In an exemplary embodiment, the shutters 3002 and 3004 of the 3D glasses 3000 may remain transparent until the 3D glasses can validate a coding signal. In an exemplary embodiment, the shutters 3002 and 3004 of the 3D glasses 3000 may alternately open and close at a frequency that allows the wearer of the 3D glasses to view normally.

Thus, method 3700 provides a method of making the operation of the 3D glasses 3000 transparent and thereby providing a TRANSPARENT mode of operation.

Referring now to Figs. 39 and 41, in an exemplary embodiment, during the operation of the 3D glasses 3000, the 3D glasses implement a method 3900 of operation wherein the control signals A, B, C, D, E , F and G generated by CPU 3012 are used to transfer load between shutters 3002 and 3004. At 3902, CPU 3012 determines if a valid synchronization signal has been detected by signal sensor 3014. If CPU 3012 determines that a signal A valid synchronization signal was detected by the signal sensor 3014, then the CPU generates the control signal C at 3904 in the form of a short pulse that lasts, in an exemplary embodiment, about 200 μsec. In an exemplary embodiment, during method 3900, charge transfer between the shutters 3002 and 3004 occurs during the short duration pulse of control signal C substantially as described above with respect to Figs 33 and 34.

At 3906, CPU 3012 determines whether the signal from

control C went from top to bottom. If CPU 3012 determines that the control signal C has gone from high to low, then the CPU changes the state of control signals A or B to 3908 and then the 3D 3000 glasses can continue normal operation of the 3D glasses, for example. as described and illustrated above with respect to Figs. 33 and 34.

Now, with reference to Figs 30a, 40 and 41, in an exemplary embodiment, during the operation of the 3D glasses 3000, the 3D glasses implement a method of operation 4000 in which the control signals RC4 and RC5 generated by the CPU 3012 are used to operate the charge pump 3016 during normal or warm-up modes of the 3D 3000 glasses as described and illustrated above with respect to Figs 32, 33, 34, 35 and 36. At 4002, CPU 3012 determines if a valid sync signal has been detected by signal sensor 3014. If CPU 3012 determines that a valid sync signal has been detected by signal sensor 3014, then the CPU generates control signal RC4 at 4004 as a series of short pulses.

In an exemplary embodiment, the control signal pulses RC4 control the operation of transistor Q1 to thereby transfer the load to capacitor C13 until the potential on the capacitor reaches a predefined level. In particular, when the RC 4 control signal changes to a low value, transistor Q1 connects inductor L1 to battery 120. As a result, inductor L1 stores energy from battery 120. Then, when the RC 4 control signal changes to a high value, the energy that was stored in the inductor Ll is transferred to capacitor C13. In this way, the RC4 control signal pulses continuously transfer charge to capacitor C13 until the potential in capacitor C13 reaches a predefined level. In an exemplary embodiment, the control signal RC4 continues until the potential in capacitor C13 reaches -12V.

In an exemplary embodiment, at 4006, CPU 3012 generates an RC5 control signal. As a result, an RA3 input signal is provided having a magnitude that decreases as the potential in capacitor C13 increases. In particular, when the potential in capacitor C13 approaches the preset value, zener diode D7 begins to conduct current, thereby reducing the magnitude of the RA3 input control signal. At 4008, CPU 3012 determines whether the magnitude of the RA3 input control signal is less than a preset value. If CPU 3012 determines that the magnitude of the RA3 input control signal is less than the default value, then at 4010, the CPU will stop generating control signals RC4 and RC5. As a result, the charge transfer to capacitor C13 ceases. In an exemplary embodiment, method 4000 may be implemented after method 3900 during operation of the 3D glasses 3000.

Referring now to Figs 30a, 42 and 43, in an exemplary embodiment, during the operation of the 3D glasses 3000, the 3D glasses implement a method 4200 of operation wherein the control signals A, B, C, D , E, F, G, RA4, RC 4 and RC 5 generated by CPU 3012 are used to determine the functional state of battery 120 when the 3D 3000 glasses are in an off status. At 4202, CPU 3012 determines whether the 3D glasses 3000 are off or on. If CPU 3012 determines that the 3D glasses 3000 are off, then the CPU determines at 4204 whether a predefined timeout period at 4204 has already expired. In an exemplary embodiment, the timeout lasts for 2 seconds.

If CPU 3012 determines that the default timeout period has elapsed, then the CPU determines at 4206 whether the number of synchronization pulses detected by signal sensor 3014 over a predefined previous time period exceeds a default value. In an exemplary embodiment, at 4206, the predefined prior time period is a time since the most recent replacement of battery 120. If CPU 3012 determines that the number of pulses

signals detected by signal sensor 3014 over a predefined period of time exceed a preset value, then the CPU at 4208 generates the control signal E in the form of a short pulse at 4210 provides the signal of control RA4 in the form of a short pulse for signal sensor 3014, and, at 4212, changes the operating state of control signals AeB, respectively. In an exemplary embodiment, if the number of synchronization pulses detected by signal sensor 3014 over a predefined prior time period exceeds a predefined value, then this may indicate that the remaining charge in battery 120 is low.

Alternatively, if CPU 3012 determines that the

The number of synchronization pulses detected by signal sensor 3014 over a predefined period of time does not exceed a preset value, then the CPU at 4210 provides the RA 4 control signal in the form of a short pulse for the signal. signal sensor 3014, and at 4212 changes the operating state of control signals A and B respectively. In an exemplary embodiment, if the number of synchronization pulses detected by signal sensor 3014 over a predefined prior time does not exceed a preset value, then this may indicate that the remaining charge in battery 120 is not low.

In an exemplary embodiment, the combination of state change of control signals AeB and the short pulse of control signal E at 4208 and 4212 causes shutters 3002 and 3004 of 3D glasses 3000 to close, except during the short pulse of control signal E. As a result, in one exemplary embodiment, shutters 3002 and 3004 provide a visual indication to the wearer of the 3D 3000 glasses that the remaining charge inside the battery 120 is low when the 3D glasses shutters blink open for a short time. In an exemplary embodiment, providing the RA4 control signal in the form of a short pulse to signal sensor 3014 at 4210 allows the signal sensor to seek and detect synchronization signals during the duration of the given pulse. In an exemplary embodiment, changing state of control signals AeB without also providing the short pulse of control signal E causes shutters 3002 and 3004 of 3D glasses 3000 to remain closed. As a result, in an exemplary embodiment, the shutters 3002 and 3004 provide a visual indication to the 3D glasses user 3000 that the remaining charge on battery 120 is not low by blinking the open 3D glasses shutters. short period of time.

In embodiments that do not have a chronological clock, time may be measured in terms of synchronization pulses. The CPU 3012 can determine the remaining time on battery 120 as a factor in the number of sync pulses for which the battery can continue to operate and then provide a visual indication to the wearer of the 3D 3000 glasses by blinking open shutters 3002 and 3004. and closed.

In an exemplary embodiment, the front frame 4402 houses the control circuitry and power supply for one or more of the 3D glasses 104, 1800, and 3000, as described above, and further defines the right and left lens apertures 4410. and 4412 for securing the right and left ISS shutters described above. In some embodiments, the front frame 4402 bends to form a right wing 4402a and a left wing 4402b. In some embodiments, at least part of the control circuitry assembly for the 3D glasses 104, 1800, and 3000 is housed in one or both wings 4402a and 4402b. In an exemplary embodiment, the right and left temples 4406 and 4408 extend from the front frame 4402 and include grooves 4406a and 4408a, and each has a serpentine shape with the ends of the temples being spaced closer to one another than the other. that in their respective connections to the front frame. Thus, when a user wears the 104, 1800, and 3000 3D glasses, the temple ends, 4406 and 4408, hug and are held in place on the wearer's head. In some embodiments, the spring rate of temples 4406 and 4408 is enhanced by double curvature, while groove spacing and depth 4406a and 4408a control the spring rate. As shown in Figure 55, some embodiments do not use a double curvature shape, but rather use a single curved temple 4406 and 4408.

Referring now to Figures 48-55, in an exemplary embodiment, the control circuitry for one or more of the 3D glasses 104, 1800 and 3000 is housed in the front frame, which includes the right wing 4402a, and The battery is housed in the right wing 4402a. In addition, in one exemplary embodiment, access to the battery 120 of the 3D glasses 3000 is provided through an opening on the inner side of the right wing 4402a which remains sealed by means of a lid 4414 including a sealing ring 4416 to get married and seal the right wing 4402a.

Referring to Figures 49-55, in some embodiments, the battery is located within a battery top assembly formed by top 4414 and inside top 4415. Battery top 4414 may be attached to the inside of battery top 4415 by means, for example, of supersonic welding. The contacts 4417 may protrude from the interior of the top 4415 to conduct electricity from battery 120 to the contacts located, for example, within the right wing 4402a.

The interior of the lid 4415 may have circumferentially spaced radial engaging members 4418 in an inner portion of the lid. Top 4414 may have circumferentially spaced holes 4420 positioned on an external surface of the top.

In an exemplary embodiment as shown in Figures 49-51, the tampon 4414 may be manipulated using a key 4422 that includes a plurality of projections 4424 to engage and mate with the holes 4420 of the tampon. In this manner the cap 4414 may be rotated relative to the right wing 4402a of the 3D glasses 104, 1800 and 3000 from a closed (or locked) position to an open (or unlocked) position. In this way, the control circuitry and battery of the 3D glasses 104, 1800, and 3000 may be sealed from the environment by fitting the top 4414 on the right wing 4402a of the 3D glasses using key 4422. Referring to Figure 55, in In another embodiment, a key 4426 may be used.

Referring now to Fig. 56, an exemplary embodiment of a signal sensor 5600 includes a narrowband filter 5602 which is operably coupled to a decoder 5604. The signal sensor 5600 is in turn coupled. operable to a CPU 5604. The narrowband filter 5602 may be an analog and / or digital bandwidth filter that may have a suitable bandwidth to allow a synchronous serial data signal to pass therethrough. while filtering and removing band noise.

In an exemplary embodiment, the CPU 5604 may, for example, be the CPU 114, the CPU 1810 or the CPU 3012, of the 3D glasses 104, 1800 or 3000. In an exemplary embodiment, during operation, the Signal sensor 5600 receives a signal from a signal transmitter 5606. In an exemplary embodiment, signal transmitter 5606 may, for example, be signal transmitter 110.

In an exemplary embodiment, signal 5700 transmitted by signal transmitter 5606 to signal sensor 5600 includes one or more data bits 5702 which are each preceded by a regulating pulse 5704. In an exemplary embodiment, during operation of signal sensor 5600, as each data bit 5702 is preceded by a throttling pulse 5704, the signal sensor decoder 5604 can quickly decode long words from many data bits. Thus, the 5600 signal sensor is capable of rapidly receiving and decoding synchronous serial data transmissions from the 5606 signal transmitter. By contrast, long data bit words, which are asynchronous data transmissions, are typically difficult to transmit and decode efficiently and / or error free. Therefore, the signal sensor 5600 provides an improved system for receiving data transmissions. Furthermore, the use of synchronous serial data transmission in the operation of the 5600 signal sensor ensures that long words of many data bits can be easily decoded.
