BACKGROUND OF THE INVENTION

Technical field

[0005] The present invention relates to a security system for portable weapons, including but not limited to crossbows and firearms such as pistols, rifles, and the like, using various sensors to ensure safe aiming, environmental data environment, location and situation in the operation of man-portable weapons.

State of the art

[0006] Portable weapons, such as crossbows and firearms, such as pistols, rifles, etc., are often used for recreational and/or sporting purposes, for self-defense when permitted by law, and/or they are carried by authorized personnel of the relevant authorities, such as police, military, etc. However, the associated security issues are always a matter of public concern. Many portable weapons in use today follow essentially the same firing sequence from pulling the trigger to hitting the bullet and so on. to shoot a bullet out of it, etc. Many of these man-portable weapons are equipped with primary safety locking mechanisms; however, these primary safety locks can be manually unlocked by the operator(s) and thus, when the primary safety locks are unlocked, there is no other means of securing handheld firearms.

[0007] A number of attempts have been made to ensure safety in the handling of man-portable weapons. For example, US Pat. No. 4,488,370 by Lemelson (Lemelson) discloses a weapon control system and a method of preventing it from being accidentally fired or used by a person other than the owner of the weapon, or anyone who is not authorized to use the weapon.

[0008] U.S. Patent No. 6,550,175 to Parker discloses a user-friendly firearm breech that is attached to the trigger guard of a firearm and in which the lock is released by properly entering a digital (or similar) pattern on the firearm's breech.

[0009] U.S. Patent No. 6,563,940 issued to Recce discloses an apparatus and method for preventing the use of a firearm by an unauthorized/unrecognized operator based on the individual pressure profile/grip profile(s) of the authorized operator(s) of the firearm located on storage.

[0010] U.S. Patent No. 9,857,133 to Kloepfer et al. (Kloepfer) and U.S. Patent Application Publication No. 2018/0142977 to Kloepfer et al. (Kloepfer 2) disclose a system and method for authenticating the identity of a weapon with biometric identification support. A biometric identification-enabled weapon contains a biometric sensor for reading the operator's biometric information (eg, a fingerprint) to determine whether the operator is authorized to use the firearm.

[0011] Many of the previous attempts, as seen in the documents Lemelson, Parker, Recce, Kloepfer and Kloepfer 2, are only concerned with whether the weapon/firearm is/is operated by an authorized operator.

[0012] Accordingly, to improve the operational safety of man-portable weapons, it is necessary to take into account the conditions of blocking and unblocking or the environment, including time, place, direction, and operator/person; however, even if such factors were taken into account, previous attempts would not provide a means for locking and unlocking the sequence of operation when fired automatically or autonomously. Therefore, there is a long overdue need to develop a primary, secondary or secondary security system, which is automatic or semi-automatic in nature, for blocking or for blocking and releasing the sequence of operation of portable weapons when fired.

DISCLOSURE OF THE INVENTION

[0013] Nowadays, gun violence has become one of the most serious public safety problems, and the search for ways to solve this problem is of public interest. When shooting occurs among the crowd in schools, churches, supermarkets, theatres, gymnasiums and other public places, the consequences can be dire. Accordingly, there has long been a need for a portable weapon safety system that only unlocks the portable weapon firing sequence when it is safe to use.

[0014] Loaded portable weapons, such as a loaded pistol, a loaded rifle, etc., are in a very dangerous state as they are ready to fire/operate. In doing research, the inventor found that the average person's reaction time to use a loaded pistol is approximately 0.3 to 0.4 seconds; and a professionally trained person can use a loaded gun for 0.1 s. In particular, the world sprint champion, Liu Xiang, showed the fastest reaction time before using weapons: 0.131 s. Accordingly, if the portable weapon is controlled so that it is in a safe state (or locked) during this reaction time, the safety of using a loaded portable weapon can become controllable.

[0015] According to an aspect of the present invention, a safety system is provided for portable weapons, including but not limited to crossbows and firearms such as pistols, rifles, and the like, using various sensors to ensure safe aiming, data on environment, location and situation in the operation of man-portable weapons. The safety system will only unlock the handheld fire sequence when it is safe to use.

[0018] The security system above further comprises a direction detection sensor for detecting the direction of the handheld weapon to cause the microcontroller to perform drive control when comparing the direction of the target and the direction of the handheld weapon. The direction detection sensor is a nine-axis displacement sensor. The nine-axis displacement sensor includes an acceleration sensor, a gyroscopic sensor, and a magnetic field sensor.

[0019] The security system described above further comprises a biometric recognition module for generating a sample of biometric data for authentication with a microcontroller to control the drive to unlock the firing sequence. The biometric recognition module is a fingerprint recognition module.

[0020] The actuator blocks the firing sequence of the trigger, trigger lever, striker, handgun striker, safety or safety catch, or a combination thereof.

[0021] In accordance with another aspect of the present invention, a security system for a portable weapon is provided, comprising: a portable weapon security controller, comprising: a first microcontroller; drive unit; and executive mechanism; and a field controller comprising a second microcontroller, the second microcontroller communicating wirelessly with the first microcontroller. The second controller causes the first microcontroller to control the drive to actuate the actuator to lock or unlock the portable weapon firing sequence. The portable weapon security controller includes a signal transmission module communicating with the first microcontroller to transmit a signal to indicate the direction to which the portable weapon is pointing, and the field controller contains a signal receiving module communicating with the second microcontroller to indicate the direction to the target, which receives the signal only when the signal transmitting module faces the signal receiving module within a predetermined range of angles. The signal may be infrared, ultrasonic, millimeter wave radar, and so on. The signal receiving module is located near the target. The field controller may optionally further comprise a gesture recognition system located at a location where the gesture recognition system would be able to track or observe an operator/shooter operating a portable weapon.

IMPLEMENTATION OF THE INVENTION

[0079] As shown in FIG. 1.1, according to a preferred embodiment of the present invention, a portable weapon security system 200a is provided that enhances safety for the operator/user of portable weapons, including, but not limited to, crossbows and firearms such as handguns, rifles, and the like, and enhances safety for the environment. A security system could prevent e.g. suicides and close range shootings, and limit the use of portable weapons to only legal and safer means (based on designated/specific time, designated/specific location, designated/specific person, designated/specific direction, etc.). .d.). The security system 200a, which may be mounted on a portable weapon, comprises a control system 100 comprising a microcontroller 1, a drive circuit 2 for controlling the lock, and an actuator 3 for actuating the lock mechanism (not shown, wherein the lock mechanism is automatic or can be driven actuated by an actuator for both locking and unlocking) to lock/unlock the handheld weapon firing sequence or to actuate a locking mechanism (not shown) to lock and enable unlocking with a locking mechanism (not shown wherein the locking mechanism is semi-automatic or can be actuated by a lock-only actuator and the actuator actuates the locking mechanism to allow manual unlocking ) the sequence of operation of portable weapons when fired (i.e. manually). The microcontroller 1 may include a microprocessor with storage device(s), such as RAM, ROM, or other type of storage device, and other peripheral devices. The control system 100 may operate on a battery P5 that includes a converter P4 for converting an output voltage V _BAT from the battery P5 to a power supply voltage V _DD for the control system 100 . The P6 battery charger (wireless or wired charger) can be used to charge the P5 battery. The security system 200a may be connected to one or more sensor devices, such as the vital signs detection module 20, to detect vital signs in the direction in which the portable weapon is pointing.

[0080] The actuator 3 may be a solenoid, a servomotor, a DC motor, or the like. to carry out the process of blocking the firing sequence (and unlocking it), for example, on the trigger, trigger lever, striker and / or striker of a portable weapon and / or on its fuse or fuse bracket. Depending on the requirements of the actuator 3, the current may be up to about 2 A. In this regard, the battery P5 may be a rechargeable lithium ion battery. Converter P4 may be a boost converter such as the Fitipower FP6717 current controlled PWM DC boost converter to convert battery output voltage V _BAT to power supply voltage V _DD for the circuit.

[0081] The battery charger P6 may be a wireless battery charger. A typical battery charger (receiver) P6 may include, for example, a T3168 unit with a receive coil for receiving wireless transmitted energy to be stored in a battery P5, and a transmitter (not shown) may include units XKT-335 and XKT-412 with a transmit coil, which corresponds to a receiving coil (not shown) for transferring energy to it.

[0082] The blocking control drive circuit 2 in the exemplary embodiment may comprise an H-bridge MOS FET IC module such as TB6612FNG.

[0083] As shown in FIG. 1.12, in the preferred embodiment of the present invention, the vital signs detection module 20 has a pyroelectric infrared sensor 42. The human body typically has a constant temperature, which is typically around 37°C. An infrared wavelength of 10 µm is emitted at or near this temperature. This radiation can be detected using a pyroelectric infrared sensor 42. First, the radiation is amplified using a Fresnel lens 43, and then concentrated on an infrared inductive source (infrared inductive sources usually use a pyroelectric component). Said pyroelectric infrared sensor 42 is configured to receive infrared radiation from a person when a change in temperature is detected.

[0084] The operation of the vital signs detection module 20 according to the present embodiment is explained below:

[0085] The vital signs detection module 20 includes a cylindrical member 41 for accommodating a pyroelectric infrared sensor 42, a lens 43, a film 44 that does not reflect infrared radiation. The cylindrical element 41 has a radius r. Lens 43 is preferably a Fresnel lens which amplifies the incoming infrared beam. The distance f between the pyroelectric infrared sensor 42 and the Fresnel lens 43 is equal to the focal length of the Fresnel lens 43. The radius of the 43 Fresnel lens is r. The thickness of the non-IR reflective film 44 is h and its radius is also r. The non-IR reflective film 44 is coated on the smooth side of the Fresnel lens 43. The structured side of the Fresnel lens 43 faces the pyroelectric infrared sensor 42. There is a distance d between the opening of the cylindrical member 41 and the non-IR reflective film 44. The angle θ is the maximum angle of incoming light (infrared radiation) that can be detected by the pyroelectric infrared sensor 42. The opening of the cylindrical member 41 is in the same direction as the weapon is pointing. The non-reflective infrared film 44 reduces the reflection and refraction loss of incoming infrared rays having a wavelength of 8 to 12 μm, thereby improving the sensitivity and accuracy of vital sign measurement by the pyroelectric infrared sensor 42. As can be seen from FIG. 1.12, the detection range or detection angle of light (infrared radiation) by the vital signs detection module 20 is in the shape of a cone, the angle of which is determined by the maximum angle θ of the incoming light. The vital signs will be detected by the vital signs detection module 20 when the person is within the range defined by the maximum angle θ. The distance d can be adjusted to change the maximum angle θ to limit/adjust the detection range of vital signs. The detection distance of the vital signs detection module 20 is 7 to 30 meters.

[0086] FIG. 1.13 illustrates a front view of the Fresnel lens 43 showing the patterned side. The Fresnel lens 43 enhances the bright and dark bands of infrared light, which makes it easier to detect different infrared rays to increase the sensitivity of the pyroelectric infrared sensor 42. The pyroelectric infrared sensors 42 detect someone's presence within the detection range determined by the maximum angle θ. The Fresnel lens 43 has a pattern on one side that includes one or more concentric rings 47 and one or more single rings 46.

[0087] To further enhance the detection sensitivity of vital signs detected by the pyroelectric infrared sensor 42, the pyroelectric infrared sensor 42 also includes a signal amplification circuit 120 shown in FIG. 1.14. The signal amplification circuit 120 contains passive infrared sensors (or pyroelectric infrared sensors) PIR1, PIR2 and amplification stages using operational amplifiers A1, A2, A3, A4 and A5, which amplify the signal corresponding to the main physiological indicator detected using passive infrared sensors PIR1 , PIR2. In a preferred embodiment of the present invention, one or more concentric rings 47 and one or more single rings 46 correspond to each of the passive infrared sensors PIR1 and PIR2. The signal amplification circuit 120 has very low DC offset, low drift, low noise, very high open loop gain, very high common mode rejection, and high input impedance. Accordingly, the common mode noise will be filtered out as much as possible, and thus the weaker original signal(s) from the pyroelectric infrared sensors PIR1 and/or PIR2 can be appropriately and sufficiently amplified, as shown in FIG. 1.14. When a person appears in front of the vital signs detection module 20, after amplifying the signal(s) from the pyroelectric infrared sensors PIR1, PIR2, a voltage Vout appears at the output of the signal amplification circuit 120, allowing you to quickly and accurately determine whether "the person is within the range discovery." The signal amplification circuit 120 includes various other components, CI, R1-R7, Rd, RP1, RP2 and VD1, VD2, where C1 is a capacitor, R1-R7 and Rd are resistors, RP1 and RP2 are adjustable resistors, a VD1 and VD2 are diodes.

[0088] The sources of the two pyroelectric infrared sensors PIR1 and PIR2 are connected respectively to the input terminal of the operational amplifiers A1 and A2, and the drains of the two sensors through the resistor Rd are connected to the system power supply V _DD . The differential amplifier circuit is formed by op-amps A1, A2, and A3 with resistors R1-R7, and the voltage comparison circuit is formed by resistors RP1 and RP2, op-amps A4 and A5, and diodes VD1-VD2. In a preferred embodiment of the present invention, the pyroelectric infrared sensor 42 is positioned such that it has at least two detection zones that may be oriented horizontally as shown in FIG. 1.15a. In appropriate cases, the vital signs detection module 20 may include more than two pyroelectric infrared sensors/passive infrared sensors, so that there may be more than two detection zones (i.e., four or more). PIR/PIR sensors are placed so that their detection zones can be oriented horizontally and vertically to improve the accuracy of vital sign detection. For example, an additional PIR/PIR pair may be placed above/below (FIG. 1.15b) or may be placed vertically across a horizontally positioned PIR/PIR pair to increase detection ranges (FIG. 1.15s).

[0089] It should be noted that circuit 120 is only intended to illustrate a typical circuit for pyroelectric infrared sensors 42 configured to detect vital signs.

[0090] FIG. 1.11 is a process flow diagram for security system 200a, and FIG. 1.11a is a state diagram depicting state transitions based on a state that indicates whether a life form has been detected or not.

[0091] As shown in FIG. 1.11 and 1.11a, at the initial stage S1-1, portable weapons can be blocked. In step S1-2, the security system 200A starts initialization and locks the handheld weapon by locking the firing sequence. Then, the security system 200a starts detecting whether any vital sign signals are present with the vital sign detection unit 20 at F 0 Hz in step S1-4. After detecting the vital signs, the security system 200a holds the mechanical lock in the locked position for security (in step S1-3, through step S1-4 (Yes)). If the vital signs signals are not detected, the security system 200a activates the mechanical locking means to make it unlocked in step S1-5 (via step S1-4 (No)), and thus the portable weapon can be safely used. Alternatively, the microcontroller 1 may include an interrupt handler or other means for handling multiple interrupts, and the output from the vital signs detection module 20 may be an input to the interrupt handler of the microcontroller 1 and thus the blocking process step S1 -3 and enable S1-5 can be executed as MCU 1 interrupt handling.

[0092] According to an aspect of the present invention, the security system may or may further comprise a direction sensor 21 or other sensor(s) as shown in FIG. 1.2.

[0093] The portable weapon security system 200b includes a control system 100 and a direction sensor 21 for determining the direction of the portable weapon and providing the determined direction to the microcontroller 1 in the control system 100. The target direction data and set values are pre-programmed/set and stored in the microcontroller 1 of the control system 100 . The direction sensor 21 of the security system 200b determines the direction in which the man-portable weapon is fired. The direction sensor 21 monitors and senses the direction of the portable weapon held/controlled by the operator. The direction sensor 21 also determines whether the man-portable weapon is pointing in the direction of the targets. The microcontroller 1 corrects the direction information/direction indication of the direction sender 21 and controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the handheld weapon firing sequence. After the microcontroller 1 detects by means of the direction sensor 21 that the handheld weapon is pointing in a direction other than the direction of the target, the microcontroller 1 controls the actuator circuit 2 to control the blocking to actuate the actuator 3 to block the handheld weapon sequence when shot to put the portable weapon out of action so that the operator cannot fire the portable weapon.

[0094] The direction sensor 21 is a virtual sensor that is based on a nine (9) axis motion sensor, comprising an acceleration sensor, a gyro sensor, and a magnetic field sensor. The data of the direction sensor 21 is acquired by an acceleration sensor, a gyro sensor, and a magnetic field sensor using a nine-axis alignment algorithm. Various commercially available sensors can be used for the present invention. For example, commonly used nine-axis align sensor components/devices may include the MPU9150, MPU9250, MPU9255, etc. sensors manufactured by InvenSense™. In a preferred embodiment of the present invention, the direction sensor 21 comprises an MPU9250 component for a nine-axis direction sensor. Other similar sensors that can be used to achieve essentially the same effects are within the scope of the present invention.

[0095] FIG. 1.21 is a process flow diagram of the security system 200b, and FIG. 1.21a is a state diagram depicting state transitions based on a state that indicates whether the handheld weapon 45 is pointing in the correct direction based on various measurements.

[0096] As shown in FIG. 1.21 and 1.21a, the security system 200b turns on in step S2-1 and goes through initialization steps S2-2. Then, the security system 200b activates the actuator 3 to block the portable weapon firing sequence in step S2-3. The direction sensor 21 generates data based on its nine-axis sensors, and the microcontroller 1 of the control system 100 collects acceleration data in S2-4, magnetic field data in S2-5, gyroscopic data in S2-6. The sequence or order in which the microcontroller 1 collects acceleration data in step S2-4, magnetic field data in step S2-5, and gyroscopic data in step S2-6 may not be important, i. the collection of said data may occur simultaneously, sequentially in any order, or may occur randomly. Next, the microcontroller 1 calculates the man-portable weapon direction data based on the data collected in step S2-7. The microcontroller 1 compares the data on the direction of the portable weapon with the direction of the target and calculates the angle of attack (S2-8). If this angle exceeds the predetermined value θ (the predetermined value θ is 45°, for example. The value θ can be adjustable), the security system 200b controls the actuator 3 to hold the lock in the locked position (step S2-3 through step S2- 8 (No)). If the specified angle is smaller than the predetermined angle θ (i.e., the direction sensor 21 indicates that the handheld weapon is pointed in the general direction of the target), the security system 200b controls the actuator 3 to unlock the weapon (step S2-9 through step S2-8 (Yes)).

[0097] The sensed data of the direction sensor 21 can be transmitted to the microcontroller 1 via the interrupt handler of the microcontroller 1 so that the direction sensor 21 provides an interrupt on the microcontroller 1 when the state changes or the direction of the handheld weapon changes.

[0098] Accordingly, the security system 200b enhances the safety of the portable weapon operators and their environment by preventing/blocking the portable weapon firing sequence when the portable weapon is pointed at a location other than the target, i. with the wrong aim.

[0099] As shown in FIG. 1.3, according to another preferred embodiment of the present invention, a portable weapon security system 200c and a corresponding field controller 300c are provided. The man-portable weapon safety system 200 is attached to the man-portable weapon to secure the man-portable weapon by locking/unlocking its firing sequence. The security system 200 comprises a portable weapon control system 100 with a signal transmission module 11 for transmitting data from the microcontroller 1 through it, and a wireless signal receiving module 10 for receiving a radio signal. The microcontroller 1 of the control system 100 in the security system 200 c drives the actuator 3 via the lock control drive circuit 2 to lock/unlock the firing sequence of the portable weapon. The field controller 300c includes a microcontroller 4, a signal receiving module 13 for receiving a signal from the security system 200c through the signal transmission module 11; and a wireless signal transmission module 12 that communicates with the microcontroller 4 to wirelessly transmit a signal to the security system 200c. The field controller 300c may communicate with more than one signal receiving module 13 .

[0100] The signal transmitting unit 11 and the signal receiving unit 13 are in wireless communication with each other. For example, the signal transmission module 11 and the signal reception module 13 may use one or more of infrared, ultrasonic, millimeter wave radar signal (or MMW, millimeter wave), etc., which is highly directional and does not scatter/reflect, so that the direction of the transmitted signal indicates the general direction in which the portable weapon is pointing. In a preferred embodiment of the present invention, the signal transmission module 11 is mounted on the portable weapon such that the signal transmission module 11 transmits a signal in the direction in which the portable weapon is pointing. It should be understood that the signal transmitting module 11 and the signal receiving module 13 may be configured such that signal detection may simply provide an indication that the handheld weapon is pointing to a safe area (or safe to use) and should not point to a target.

[0101] The wireless signal transmission module 12 and the wireless signal reception module 10 communicate with each other wirelessly, such as using Bluetooth™ technology, Wi-Fi™, and/or other wireless communication methods. The wireless transmission module 12 may include, for example, a pt2272 component (a remote control decoder manufactured by Princeton Technology Corp), a pt2262 component (a remote control decoder manufactured by Princeton Technology Corp), a Bluetooth™ module, a Wi-Fi™ module, and other modules. wireless connection. Other similar wireless modules that can be used to achieve essentially the same results/same effect.

[0102] FIG. 1.31a is a process flow diagram for a security system 200c in conjunction with a field controller 300c, FIG. 1.31b is a process flow diagram for field controller 300c in conjunction with security system 200c, FIG. 1.32a is a state diagram depicting the state transitions of the security system 200c based on a state that indicates whether a signal from the field controller has been detected; and in FIG. 1.32b is a state diagram depicting state transitions of the field controller 300c based on a state that indicates whether a direction signal has been received from the security controller 200c.

[0103] First, the security system 200c and the field controller 300c start up in steps S3a-1 and S3b-1, respectively, and go through initialization steps S3a-2 and S3b-2, respectively. During the initialization in step S3a-2, the security system controls the signal transmission unit 11 to transmit a detection signal at a frequency F 0 Hz, and then the microcontroller 1 initiates the actuator 3 through the blocking control drive circuit 2 to block the sequence of the portable weapon when fired at step S3a-3. Once the firing sequence is disabled, the microcontroller 1 waits for a radio signal to be received via the wireless signal receiving module 10 from the field controller 300c (step S3a-4). The field controller 300c, after starting it in step S3b-1, initiates the initialization process in step S3b-2. The field controller 300c, via the wireless signal transmission module 12, can transmit a radio signal to the security system 200c to block the firing sequence in step S3b-3. This step may be optional, but it can be performed to ensure that the security system 200c is in a locked state. If the security system 200c detects a signal from the field controller 300c (step S3a-4), the microcontroller 1 of the security system 200c controls the actuator 3 via the lock control actuator circuit 2 to unlock the portable weapon firing sequence in step S3a-5 (via step S3a-4 (Yes)); otherwise, the microcontroller 1 of the security system 200c controls the actuator 3 via the lock control drive circuit 2 to lock the portable weapon firing sequence in step S3a-3 (through step S3a-4 (No)). Alternatively, in the state of step S3b-3, the field controller 300c may not transmit any radio signal to the security system 200c, and thus the security system 200c will only unlock the handheld weapon firing sequence when the security system 200c security will receive an "unlock" signal.

[0104] In a preferred embodiment of the present invention, the signal receiving module 13 may be an infrared detection module, similar to the module shown in FIG. 1.12, and the signal transmission module 11 may be an infrared emitter that is mounted on a portable weapon. The signal receiving unit 13 has a specific set of values for the parameters r, d, and f of the pyroelectric infrared sensor to determine the detectable detection angle/range θ, as shown in FIG. 1.12. If the angle between the signal transmission direction _θt and the signal reception direction _θR is smaller than the predetermined value θ (the set value θ is 45° and can be adjusted), the signal receiving module 13 of the field controller 300c may receive a detection signal from the transmission module 11. The microcontroller 4 checks whether the signal receiving module 13 receives a signal from the signal transmission module 11 . The field microcontroller 4 controls the wireless signal transmission module 12 to send a radio signal to the security system 200c to enable the firing sequence in step S3b-5 through step S3b-4 (Yes) if the signal is detected, or to disable the firing sequence if no signal detected in step S3b-3 through step S3b-4 (No).

[0105] As can be seen from FIG. 1.32a, the security system 200c has only two states: locked (step S3a-3) or unlocked (step S3a-5). In this regard, the security system 200S should only enter the "unlocked" state in step S3a-5 if and when the security system 200c receives/received an "unlock" signal from the field controller 300c; otherwise, the security system 200c should be in the “lock” state in step S3a-3 (i.e., a positive detection of the “lock” signal or a negative detection of the “unlock” signal should cause the security system 200c to be in blocking state in step S3a-3).

[0106] Similarly, as shown in FIG. 1.32b, the field controller 300c has only two states: sending a "lock" signal (or a state in which no sending occurs) in step S3b-3 or sending a "unlock" signal in step S3b-5. This decision will be made by the field controller 300c based on whether a direction signal is received (in step S3b-4).

[0107] The signal transmission module 11 may include an infrared emitter 51 in a housing 52, the shape of the housing 52 being cylindrical as shown in FIG. 1.3a, or conical, as shown in FIG. 1.3b.

[0108] One or more signal receiving modules 13 of the field controller 300c may be mounted around the target or on the wall of the bullet box.

[0109] The signal transmitting module 11 and the signal receiving module 13 may comprise an ultrasonic transmitter and receiver, a millimeter wave radar transmitter and receiver, and other similar transmitting and receiving modules, any of which can be used to achieve essentially the same direction detection results. , where the portable weapon is pointing.

The operating principle of this embodiment of the present invention is similar to that shown in FIG. 1.3. The security system controller 200d is installed on the portable weapon, the control system 100 of the security controller 200d includes a microcontroller 1, a drive circuit 2 for locking control, and an actuator 3 for driving the means for locking/unlocking the portable weapon firing sequence, and a signal receiving module 13a for receiving/detecting the detection signal transmitted by the signal transmission unit 11a which is installed in the field. The signal receiving unit 13a is connected to the microcontroller 1. The signal transmission unit 11A is configured to transmit a detection signal. The control system 100 of the security controller 200d unlocks the portable weapon firing sequence only when the signal receiving unit 13a receives/detects the detection signal transmitted by the signal transmission unit 11a.

[0111] In a preferred embodiment of the present invention, the signal transmission module 11a comprises an infrared laser transmitter such as HLM1235 or the like; and the signal receiving unit 13a includes an infrared laser receiving tube such as ISO203 or the like.

[0112] FIG. 1.41 is a flow diagram for a security system 200d in cooperation with a signal transmission module 11a; and in FIG. 1.41a is a state diagram depicting the state transitions of the security system 200d based on a state that indicates whether an infrared receiver has received an infrared laser signal.

[0113] For example, after startup in step S4-1 and initialization in step S4-2 of the security system 200d, the microcontroller 1 of the security system 200d controls the lock control actuator circuit 2 to actuate the actuator 3 to lock the handheld weapon sequence. when fired in step S4-3. Next, the microcontroller 1 monitors whether the signal receiving unit 13a has received the signal generated by the signal transmitting unit 11a in step S4-4. Upon detecting this, the microcontroller 1 controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the handheld weapon firing sequence, thereby enabling the handheld weapon to be fired in step S4-5 through step S4-4 (Yes); otherwise, the microcontroller 1 maintains locking the portable weapon firing sequence in step S4-3 through step S4-4 (No).

[0114] As shown in FIG. 1.5, according to another aspect of the present invention, a portable weapon security system 200e is provided that is mounted on a portable weapon and a field controller 300e that communicates with the security system 200e.

[0115] The security system 200e includes a control system 100 comprising a microcontroller 1 for controlling a lock control actuator circuit 2 to actuate an actuator 3 for locking/unlocking a handheld weapon firing sequence. The microcontroller 1 of the control system 100 communicates with the wireless signal receiving module 10 . The field controller 300e includes a microcontroller 4 that communicates with a gesture recognition system 22 and a wireless signal transmission module 12. The gesture recognition system 22 may comprise one or a combination of the following: a binocular camera gesture recognition system, an optical structured light gesture recognition system, a TOF-based gesture recognition system, an ultrasonic gesture recognition system, a millimeter wave radar gesture recognition system, and a gesture recognition system. based on image processing using AI. The field controller 300e also communicates with the wireless signal transmission module 12, which transmits a radio signal to the wireless signal reception module 10 of the security system 200e.

1) AI Image Recognition System:

[0116] As shown in FIG. 1.5a, the AI image processing based gesture recognition system 22a may comprise an AI image recognition system. The image capturing device/element(s) for the AI image processing based gesture recognition system 22a can be installed at a location where the operator 60 of the portable weapon 45 can be tracked and captured. In the case of application of the present invention in a shooting range or equivalent location, the device/element for capturing an image can be installed in front of the sighting machine.

[0117] The AI image recognition system is configured to recognize a human gesture and the direction in which the handheld weapon 45 is pointing. and processed by the security 200e to determine whether it is safe to operate the handheld weapon 45. If the AI image recognition system detects that a person is in front of the handheld weapon 45, the field controller 300e processes such information to send a signal to block the handheld weapon sequence. 45 when fired, or the field controller 300e may send the detected/calculated direction data of the handheld weapon 45 to the security system 200e via the wireless signal transmission module 12 so that the microcontroller 1 of the security system 200e you could process this data to determine the safety and block the sequence of the portable weapon 45 when fired.

[0118] The image recognition system using the AI of the field controller 300e determines the direction of the handheld weapon 45 and this data can be used to determine whether the handheld weapon 45 is pointing at a target 40 in the range or there is a person in front of the handheld weapon 45. The microcontroller 4 of the field controller 300e may process the detected directional data to determine the safety of the firing sequence of the handheld weapon 45 and send a command to the security system 200e via the wireless signal transmission module 12 and the wireless signal reception module 10 as to whether to lock or unlock. the sequence of operation of portable weapons 45 when fired; or may transmit the detected data via the wireless signal transmission module 12, wherein the wireless signal receiving module 10 of the security system 200e receives the wireless data to the microcontroller 1, and the microcontroller 1 can process the detected data to determine whether the handheld weapon 45 firing sequence is safe and determine whether whether the locking control drive circuit 2 should be controlled to actuate the actuator 3 to lock or unlock the firing sequence of the handheld weapon 45.

2) Gesture recognition system based on myoelectric sensor:

[0119] As shown in FIG. 1.5b, the gesture recognition system 22 may include a gesture recognition system 22b based on a myoelectric sensor.

[0120] A gesture recognition system 22b based on the myoelectric sensor of the field controller 300e can be worn on the hand(s) 61 of the operator 60 with a portable weapon 45 (i.e., one or more myoelectric sensors can be placed on the hand 61) to collect data about the myoelectric signal and gesture of the hand(s) 61 and calculating the movement of the hand for gesture recognition.

[0121] The myoelectric sensor based gesture recognition system 22b includes: a myoelectric sensor(s) 220 and a movement sensor(s) 225. There are a number of proven products and modules that are on the market. The direction in which the handheld weapon 45 is pointing is calculated based on the data collected by the myoelectric sensor(s) 220 and the movement sensor(s) 225, and this data is used to determine whether to lock or unlock the handheld weapon 45 sequence when shot. The myoelectric sensor(s) 220 on the arm(s) 61 monitors the movement of the arm(s). The microcontroller 4 of the field controller 300e calculates the direction in which the handheld weapon 45 is pointing using the collected data from the recognition system 22b based on the myoelectric sensor. The data will be processed by the microcontroller 4 of the field controller 300e or may be transmitted to the security system 200e via the wireless signal transmission module 12/wireless signal reception module 10 so that the microcontroller 1 can process the collected data. The field controller microcontroller 4 or the security system 200e microcontroller 1 uses the collected data to compare with the position data of the target 40. If the direction in which the portable weapon 45 is pointing is outside a certain range relative to the target 40, the first microcontroller 1 controls the drive circuit 2 to a blocking control for actuating the actuator 3 to block the sequence of operation of the portable weapon 45 when fired to ensure safety. Only if the direction in which the handheld weapon 45 is pointing is in a safe direction/area and the operator is holding the handheld weapon 45 using a predetermined appropriate handheld weapon 45 related gesture (e.g., detected data from the myoelectric sensor(s) 220 and movement sensor(s) 225 can be analyzed to confirm that the operator holds the portable weapon 45 with both hands and aims it at the target 40), A signal indicating the inherent sign of holding the portable weapon 45 with both hands is collected using a myoelectric sensor (s) 220, after which 45 portable weapons are allowed to fire. Otherwise, the microcontroller 1 controls the blocking control actuator circuit 2 to actuate the actuator 3 to block the firing sequence of the portable weapon 45 for safety.

[0122] In a preferred embodiment of the present invention, the myoelectric sensor gesture recognition system 22b may be an OYMotion™ gesture recognition armband, such as the gForce Armband™, which may include eight (8) myoelectric sensors and one (1 ) displacement sensor. The myoelectric sensor gesture recognition system 22b is configured to recognize common gestures such as holding the handheld weapon 45 with both hands, holding the handheld weapon 45 with one hand, pulling the trigger with the index finger, and holding the handheld weapon 45 and aiming at the target 40 and etc. The gesture recognition armband captures the biological current on the operator's arm(s) as well as the acceleration/movement data of the operator's arm(s). Accordingly, based on the collected data, microcontroller 4 or microcontroller 1 or both microcontroller 4 and microcontroller 1 can calculate the handheld weapon 45 holding gesture(s) by the operator.

[0123] The myoelectric sensor based gesture recognition system 22b can be calibrated/adjusted under the following conditions. Ten (10) healthy individuals aged 30 years were selected. Four (4) different movements/actions of each person were recorded as a sample. Each person then performed each action fifty (50) times; after that, each person performed four (4) actions two thousand (2000) times. All of these actions/movements performed were recorded as test samples to improve the accuracy of the gesture recognition system 22b based on the myoelectric sensor. The number of people and/or the number of repetitions of action movements can be increased to improve the recognition accuracy of the gesture recognition system 22b based on the myoelectric sensor. In a preferred embodiment of the present invention, the sampling rate of the myoelectric sensor is 200 Hz and the sampling rate of the acceleration/displacement sensor is 50 Hz. The eigenvalues for each action in the test set are extracted and used as eigenvalues to detect matching/non-matching gestures to control the lock/unlock sequence of the handheld weapon 45 when fired. Once the predetermined eigenvalues are predetermined and predetermined, the detected gestures of the handheld weapon 45 shooter can be compared to determine if the handheld weapon 45 is safe to perform the firing sequence. If the range of errors between the movement while holding the portable weapon 45 towards the target 40 by the operator and its own value is within, for example, 10%, it is considered that the shooter correctly aimed the portable weapon 45 at the target 40. In this case, the microcontroller 1 controls the drive circuit 2 for blocking control for actuating the actuator 3 to unlock the sequence of the portable weapon 45 when fired. If the error range between the movement while holding the portable weapon 45 towards the target 40 by the shooter 60 and its own value exceeds 10%, the microcontroller 1 controls the drive circuit 2 to control the blocking to actuate the actuator 3 to block the sequence of the portable weapon 45 when fired .

[0124] The myoelectric sensor based gesture recognition system 22b can also be used to build a 3D model of the portable weapon 45 and calculate the spatial coordinates of the portable weapon 45. The microcontroller 4 can be configured to send the spatial coordinate of the portable weapon 45 to the wireless signal receiving module 10. The security system 200e receives the spatial coordinate data and calculates the angle between the direction of the handheld weapon 45 and the target 40, when the direction of the handheld weapon 45 is outside a certain range of direction to the target 40, indicated above as 45°, the microcontroller 1 is configured to control the drive circuit 2 to control the blocking to actuate the actuator 3 to block the sequence of operation of the portable weapon 45 when fired, thus ensuring the safety of the use of the portable weapon 45.

[0125] The myoelectric sensor based gesture recognition system 22b may be a DTing™ wristband/myoelectric technical system or other similar device that will provide substantially the same performance.

3) Time of flight (ToF) gesture recognition system:

[0126] As shown in FIG. 1.5d, according to another preferred embodiment of the present invention, the gesture recognition system 22 is a time-of-flight (ToF) gesture recognition system 22d, in which the ToF camera(s) can be located in front of the sighting machine when on a shooting range or in a location where The ToF camera(s) is capable of capturing images of the movement of an operator 60 using a portable weapon 45.

[0127] ToF gesture recognition system 22d may be a Geefish™ Tech gesture recognition ToF system that includes an emitter 22d(a) that emits near-infrared modulated light pulses and a sensor(s) 22d(b) used to track the hand(s)/hand 61 of the hand(s) of the operator 60 holding the portable weapon 45. The ToF gesture recognition system 22D is configured to measure the distance to the hand 61 holding the portable weapon and construct a three-dimensional contour of the hand 61. Microcontroller 4 may be configured to perform machine learning, including, for example, a deep learning algorithm, to obtain a profile of the handheld weapon held by the operator 60. After normalization of the characteristics, the microcontroller 4 is configured to recognize various common handheld weapon holding gestures, including, without limitation, the gesture holding a portable weapon with both hands 61; or with one hand 61; gesture of pressing the trigger with the index finger; and holding the portable weapon 45 and pointing it at the target 40. In the case of using machine learning, similar to the aforementioned myoelectric gesture detection devices, the ToF gesture recognition system 22D can be calibrated/adjusted under the following conditions. For example, five (5) healthy individuals aged 30 years were selected and each individual performed four (4) different movements to collect data. Each move was performed by each person 40 times and data was collected. In a preferred embodiment of the present invention, the gesture recognition TOF system 22D is configured to provide a frame rate of 45 frames per second (fps) to sample/track the movement of the hand(s) 61 of the operator 60. Eigenvalues for each movement in The test samples are collected and analyzed to determine eigenvalues for evaluating the holding gestures of the operator 60. In this regard, the gestures of the operator 60 are monitored and compared with the characteristics of the test samples to determine which one of the four different movements/gestures was performed by the operator 60. If the range of errors between the movement while holding the portable weapon towards the target 40 and its own value is within, for example, 10%, then the operator, apparently, correctly directed the portable weapon at the target 40. In this case, the microcontroller 1 controls the drive circuit 2 to control the blocking to bring in the action of the actuator 3 to unlock the sequence of the portable weapon when fired. If the range of errors between the movement while holding the portable weapon pointing at the target 40 by the operator 60 and its own value exceeds 10% of the error range, the microcontroller 1 controls the drive circuit 2 to control the blocking to actuate the actuator 3 to block the sequence of the portable weapon when shot. The ToF gesture recognition system 22D can also be configured to build a 3D model of the handheld weapon and calculate the spatial coordinates of the two ends of the handheld weapon. The field controller 300e is configured to transmit the spatial coordinate to the wireless signal receiving module 10, and the security controller 200e is configured to receive the spatial coordinate data. By calculating the angle between the direction of the handheld weapon and the target 40, the microcontroller 1 determines whether to control the lock control actuator circuit 2 to actuate the actuator 3 to lock or unlock the handheld weapon firing sequence.

The structure and principle according to this embodiment are similar to the ToF gesture recognition system 22D shown in FIG. 1.5d.

5) Gesture recognition system with binocular camera:

[0129] As shown in FIG. 1.5e, according to another preferred embodiment of the present invention, the gesture recognition system 22 is a gesture recognition system 22e with a binocular camera.

[0130] An exemplary embodiment of the binocular camera gesture recognition system 22e may be the Leap Motion™ Rev.6 gesture recognition system. The binocular camera gesture recognition system 22e can be placed in front of the operator 60 using the handheld weapon 45 and preferably faces the operator 60 such that the movements of the handheld weapon 45 during its use by the operator 60 are within the detection range of the two cameras 22e(a). , 22e(b) of a gesture recognition system 22e with a binocular camera. Based on the principle of binocular stereoscopic perception, gesture information including 3D position is calculated and a stereo model of the weapon holding gesture is built. Next, the binocular camera gesture recognition system 22e is configured to track the gestures of the operator 60 while using the handheld weapon 45. The binocular camera gesture recognition system 22e can be used to identify common gestures such as holding the handheld weapon 45 with both hands, holding the handheld weapon 45 with one hand, pulling the trigger with the index finger, as well as holding the portable weapon 45 with one hand and aiming at the target 40; etc. The binocular camera gesture recognition system 22e can be calibrated/adjusted under the following conditions. Twenty (20) healthy people of a certain age were selected and data were collected on four (4) different movements of each person. Each action was performed 50 times and data associated with these actions was collected. In the preferred embodiment of the present invention, the binocular camera gesture recognition system 22e tracks hand gesture movements at 120 frames per second (fps). The eigenvalues for each movement in the test sample are extracted and used as eigenvalues for control. Accordingly, these movements are compared with the characteristics of the movements in the samples to determine the type of movement/gesture performed by the operator 60. If the error range between the captured movement and the eigenvalue is less than 10%, the operator 60 is considered to have correctly aimed the portable weapon 45 at the target 40. When Here, the microcontroller 1 controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the firing sequence of the handheld weapon 45. If the error range between the captured motion and the eigenvalue exceeds 10%, the microcontroller 1 controls the lock control actuator circuit 2 to actuate the actuator 3 to lock the firing sequence of the handheld weapon 45.

[0131] The binocular camera gesture recognition system 22e can also be configured to build a 3D model of the portable weapon 45 and calculate the spatial coordinates of the portable weapon 45. The field controller 300e sends the spatial coordinate of the portable weapon 45 to the wireless signal receiving module 10. The security system 200e receives the spatial coordinate data and calculates the angle between the direction of the handheld weapon 45 and the direction of the target 40. If the direction of the handheld weapon 45 and the direction of the target 40 are not within a certain range, such as more than 45°, the first microcontroller 1 controls the circuit 2 a blocking control actuator for actuating the actuator 3 to block the sequence of the portable weapon 45 when fired.

[0132] The following binocular camera gesture recognition systems currently exist: Leap Motion™, uSens™, Gee Fish™ Tech, Untouch™, Vivid™ Tech.

6) Gesture recognition system based on structured light:

[0133] As shown in FIG. 1.5f, according to another preferred embodiment of the present invention, the gesture recognition system 22 is a structured light gesture recognition system 22f that uses a process of projecting a known pattern onto an operator 60 with a portable weapon 45 and tracking images with a known pattern projected onto the operator. 60 and a portable weapon 45. The structured light gesture recognition system 22F is installed at a location where cameras will be able to capture the movement of an operator using a portable weapon.

[0134] The structured light gesture recognition system 22F may be an Orbbec™ 3D sensor camera that can be placed in front of a sighting machine on a range and facing an operator 60 with a portable weapon 45. The structured light gesture recognition system 22F is configured with the possibility of using an invisible light emitter, such as an infrared projector 22f(a), in which the coded infrared laser beam / known pattern is projected onto the arm (s) / hand 61 of the hand (s) of the operator 60, which holds the portable weapon 45, and the receiver 22f(b) (standard CMOS sensor) receives the infrared laser pattern(s) reflected from the hand/hand 61 of the hand that holds the portable weapon 45 and the data for further processing. The position and details of the arm(s)/hand(s) 61 of the arm(s) that holds the portable weapon 45 can be calculated based on the collected data, and enables calculation/determination of the pattern shift change when the hand 61 holding the portable weapon 45 is moved. and then generating/saving the entire 3D space. For example, a nearest neighbor algorithm can be used to obtain data about the movements or gestures of the hand(s) 61 of the operator 60 that holds the portable weapon 45. Using a support vector machine (SVM), the structured light gesture recognition system 22f can be trained to recognize movement characteristics associated with the handling of man-portable weapons 45 using a set of training data samples. Finally, common gestures can be identified, such as holding a portable weapon 45 with both hands 61; holding a portable weapon 45 with one hand 61; pressing the trigger with the index finger and pointing at the target 40 with one hand 61; as well as targeting.

[0135] The structured light gesture recognition system 22f can be calibrated/customized under the following conditions. For example, fifteen (15) healthy people belonging to a certain age group were selected, and each of them performed four (4) different movements. Each move was performed 50 times by each person to correct the sample data. 3000 groups of weapon holding gestures were received. These sample data were transferred to the support vector machine for analysis. In this preferred embodiment of the present invention, the gesture recognition system 22 samples gestures/movements at a rate of 30 frames per second (fps). Eigenvalues for each movement in the sample are calculated and used as eigenvalues for control. When capturing a gesture performed by a shooter, the captured gestures are compared with characteristics of the samples to determine what type of movement the portable weapon shooter is performing. If the range of error between the captured movement of the handheld weapon held by the shooter towards the target and its own value is within 10%, the handheld weapon is considered to be correctly pointed at the target. In this case, the microcontroller 1 controls the drive circuit 2 to control the lock to actuate the actuator 3 to unlock the sequence of the portable weapon when fired. If the range of errors between the captured motion and the eigenvalue is outside the 10% range, the microcontroller 1 controls the actuator circuit 2 to control the blocking to actuate the actuator 3 to block the firing sequence of the portable weapon.

[0136] The structured light gesture recognition system 22e can also be configured to build a 3D model of the portable weapon 45 and calculate the spatial coordinates of the portable weapon 45. The field controller 300e is configured to send the spatial coordinate of the portable weapon to the wireless signal receiving module 10. The security system 200e receives the spatial coordinate data and calculates the angle between the direction of the handheld weapon 45 and the direction of the target 40. a blocking control actuator circuit 2 for actuating the actuator 3 to block the sequence of operation of the portable weapon when fired.

[0137] For example, the structured light gesture recognition system of the gesture recognition system 22 may be selected from the group consisting of: Mantis Vision™, Prime Sense™, Pmek™, RealSense™, and Orbbec™.

[0138] FIG. 1.51 and 1.52 are examples of process flow diagrams in accordance with the present invention. FIG. 1.51a is a state diagram depicting state transitions based on a state that indicates whether the handheld weapon 45 is pointed in the correct direction based on various measurements.

[0139] FIG. 1.51 shows an example of a process flow diagram, and FIG. 1.51a shows an example state diagram of the microcontroller 1 of the security system 200e. The security system 200e is started (step S5-a1) and initialized by downloading the heading data to the target 40, which is one of the most important parameters for controlling the locking control actuator 2 to actuate the actuator 3 for locking/unlocking the portable weapon 45 ( step S5-a2). The security system 200e controls the lock control actuator 2 to actuate the actuator 3 to lock the portable weapon 45 (step S5-a3). Then, the security system 200e receives and monitors the direction data of the portable weapon 45 from the wireless signal receiving module 10 (step S5-a4). Based on the direction of the handheld weapon 45 and the direction of the target 40, the security system 200e calculates the difference in angle between the direction of the handheld weapon 45 and the direction of the target 40. be adjusted), the microcontroller 1 controls the lock control drive circuit 2 to drive the actuator 3 to lock the firing sequence (in step S5-a3 through step S5-5a (No)). If the deflection angle is smaller than the predetermined value θ, the microcontroller 1 controls the lock control drive circuit 2 to drive the actuator 3 to unlock the firing sequence (at S5-a6 through S5-5a (YES)).

[0140] In FIG. 1.52 is an example of a process flow diagram for microcontroller 4 of a 300e field controller.

[0141] The field controller 300e starts initialization (at step S5-b1), and then is initialized when downloading gesture data based on the sample data (at step S5-b2). As soon as the gesture recognition system 22 starts outputting data, the microcontroller 4 receives data from it for processing (in step S5-b3). The microcontroller 4 converts this received data into data on the direction of the portable weapon 45 (in step S5-b4). Finally, this data will be transmitted by the wireless signal transmission unit 12 (in step S5-b5).

[0142] As shown in FIG. 1.6, according to another preferred embodiment of the present invention, a portable weapon security system 200f is provided that includes a control system 100 and a weapon location module 23 that communicates with the microcontroller 1 of the control system 100. The security system 200f is mounted on the man-portable weapon 45.

[0143] This security system 200f is suitable for use in shooting or similar situations, as well as for controlling portable weapons 45. When used on a shooting range, the security system 200f is designed in such a way that portable weapons 45 can only be used within the permitted area inside the shooting range. If, for example, the portable weapon 45 is taken out of the shooting range, the security system 200f blocks the firing sequence of the portable weapon 45, and thus the portable weapon 45 cannot be used for firing. Based on the experiments and tests carried out by the present inventors, it was found that the security system 200f was able to block the portable weapon 45 for about 0.1 second.

[0144] To improve the security of portable weapons such as firearms, this security system 200f is configured to allow the operator 60 of the portable weapon 45 to use only within a predetermined authorized area(s). The weapon location module 23 uses a wireless sensor network location technology and a global positioning system (CP5)/Augmented Global Positioning System (A-GPS) location technology to determine the location of the man-portable weapon 45. For the present invention and for the same purpose, a system other than GPS may be used, including, without limitation, BeiDou (BeiDou Navigation Satellite System (BDS), Galileo (or Global Navigation Satellite System (GNSS)) or other positioning system. The wireless sensor network location technology may be configured to use ultrasonic wave, blue tooth, Wi-Fi, ZigBee, RFID, ultra-wideband, or other similar method to locate a handheld weapon.

[0145] FIG. 1.61 shows an example process flow diagram of the microcontroller 1 of the security system 200f. After the security system 200f is started (in step S6-1), it goes through the initialization process in step S6-2 and downloads predetermined coordinates/location information related to the allowed/allowable area(s) in which the operator 60 can control the portable the weapon 45. The security system 200f then blocks the sequence of the portable weapon 45 when fired. If, during operation of the security system 200f, the data collected by the weapon position module 23 indicates that the handheld weapon 45 is in the enabled position, the microcontroller 1 in the security system 200f controls the drive circuit 2 to control the lock to actuate the actuator 3 to unlock the firing sequence of the portable weapon 45 (at S6-5 through S6-4 (YES)). If the data collected by the weapon position module 23 indicates that the portable weapon 45 is outside the predetermined allowed zone, the microcontroller 1 in the security system 200f controls the lock control actuator circuit 2 to actuate the actuator 3 to lock the sequence operation of the portable weapon when fired (at step S6-3 through step S6-4 (No)).

[0146] As shown in FIG. 1.7, according to another aspect of the present invention, a man-portable weapon security system 200d is provided, comprising a control system 100 and a biometric sensor/recognition module 24 (ie, for fingerprint recognition). The security system 200g further comprises a wireless remote control signal receiver module 14 that is configured to wirelessly and remotely communicate with the remote controller 300g.

[0147] The biometric fingerprint sensor/module 24 allows the operator 60 to use their unique biometric data (i.e., fingerprints) to lock or unlock the handheld weapon 45. The security system 200g can store data for more than one fingerprint for more than one person. For example, in a shooting range, the security system 200g may store fingerprint data for an administrator, supervisor, and other authorized personnel on the shooting range to lock/unlock the portable weapon 45.

[0148] If during the use of the portable weapon 45, the administrator detects any abnormal or unsafe condition(s)/situation(s) in the behavior of the operator 60 or in his environment, the administrator can use the remote controller 300g to control the drive circuit 2 to control the lock to actuate the actuator 3 to lock the firing sequence of the handheld weapon 45 (the unlock that was initiated by the biometric sensor/fingerprint recognition module 24 will be cancelled). In other words, the release of the fire sequence of the handheld weapon 45 occurs only when both the remote controller 300g and the biometric fingerprint sensor/module 24 allow the fire sequence of the handheld weapon 45 to be released. To further increase the safety of the operation of portable weapons 45, the security system 200d needs to provide biometric information (fingerprints) of more than one person, i.e., for example, the manager and administrator of the shooting range.

[0149] Various other types of authentication technologies/methods may be applied instead of or in addition to biometric information, as shown below.

[0150] As shown in FIG. 3.31 and 3.32, the security system 200j(1) includes a control system 100 and an RFID card reader 81 that communicates with the microcontroller 1 of the control system 100 to read the RFID card 80. The security system 200j(1) unlocks the handheld weapon only when the RFID card reader 81 successfully reads the RFID card 80 and verifies that the RFID card 80 belongs to an authorized person/personnel. After authentication, the microcontroller 1 controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the handheld weapon firing sequence. Accordingly, failure to read the RFID card 80 by the RFID card reader 81, or failure to validate/authenticate, may cause the microcontroller 1 to control the actuator circuit 2 to control the lock to actuate the actuator 3 so as to block the operation sequence. portable weapon when fired, so that the portable weapon cannot be used/cannot be fired from.

[0151] As shown in FIG. 3.41 and 3.42, the security system 200j(2) includes a control system 100, a dynamic password generator 83, an input device 84 or a keyboard and a display 85 that communicate with the microcontroller 1 of the control system 100. The dynamic password generator 83 also generates random dynamic passwords at the same rate as the dynamic password card 82. Accordingly, an authorized person/personnel can enter a randomly generated password using the dynamic password card 82 through the input device 84 . Only if the password entered by the input device 84 matches the password generated by the dynamic password generator 83, the microcontroller 1 controls the actuator circuit 2 to control the lock to actuate the actuator 3 to unlock the handheld weapon sequence when shot; otherwise, the microcontroller 1 controls the blocking control drive circuit 2 to actuate the actuator 3 to block the firing sequence of the portable weapon so that the portable weapon cannot be used/fired.

[0152] As shown in FIG. 3.51 and 3.52, the security system 200j(3) includes a control system 100 and a physical chip card reader 86 that communicates with the microcontroller 1 of the control system 100. When the physical chip card 87 is inserted into the physical chip card reader 86, the control system 100 performs authentication. Only after successful authentication, the microcontroller 1 controls the drive circuit 2 to control the lock to actuate the actuator 3 to unlock the portable weapon firing sequence; otherwise, the microcontroller 1 controls the blocking control actuator circuit 2 to actuate the actuator 3 to block the firing sequence of the portable weapon so that the portable weapon cannot be used/fired.

[0153] FIG. 1.71 is an example of a process flow diagram of a security system 200g. For example, after the security system 200g is started (in step S7-1), it is initialized (in step S7-2), for example, when biometric data of more than one authorized person is uploaded, i. e. leader and administrator. The security system 200g will block the firing sequence of the handheld weapon 45 only when the security system 200g receives an emergency override signal (in step S7-3) and if more than one authorized person has entered the wrong biometric data (or password, for example, on S7-5, S7-6), the security system 200g maintains the locked state of the portable weapon 45.

[0154] First, the security system 200g checks whether any remote control signal in an accident has been received from the remote controller 300g to block the portable weapon (in step S7-3). If a remote emergency control signal for locking the portable weapon 45 is received, the microcontroller 1 of the security system 200d controls the lockout control drive circuit 2 to actuate the actuator 3 to lock the firing sequence of the portable weapon 45 (in step S7-4) ; otherwise, the microcontroller 1 of the security system 200g continues to monitor the remote control signals in the event of an accident. After blocking (in step S7-4), the security system 200d further checks whether the fingerprint of the first authorized person (supervisor) is entered correctly (in step S7-5). If not, the microcontroller 1 of the security system 200g controls the lock control actuator circuit 2 to actuate the actuator 3 to lock the firing sequence of the handheld weapon 45 (at step s7-4); otherwise, a check will be made whether the fingerprint of the second authorized person (supervisor) is entered correctly (in step S7-6). If not, the microcontroller 1 of the security system 200g controls the lock control actuator circuit 2 to actuate the actuator 3 to lock the firing sequence of the handheld weapon 45 (at step s7-4). Otherwise, the microcontroller 1 of the security system 200g controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the firing sequence of the handheld weapon 45 (at step s7-7).

Combined Embodiment 1

[0155] A combination of two or more of the aforementioned security sensors/modules can be used to improve the safety of a portable weapon. For example, as shown in FIG. 2.1, the man-portable weapon security system 200h may include a vital sign detection module 20, a weapon location module 23, and a direction sensor 21. The vital signs detection module 20 includes a pyroelectric infrared sensor 42. The weapon location module 23 includes a GPS module 25 and an internal location system using a wireless sensor network as described above. For the present invention and for the same purpose, technology other than GPS may be used, including but not limited to BeiDou (BeiDou Navigation Satellite System (BDS), Galileo (or Global Navigation Satellite System (GNSS)) or other positioning system. The direction sensor 21 uses a nine (9) axis displacement sensor. Authorized personnel (ie, range management personnel) can decide which zones are considered restricted or unrestricted using the weapon location module 23 . When said weapon location module 23 is installed on the portable weapon 45, the security system 200h tracks its current location. The shooter 60 with the portable weapon 45 will only be able to use the portable weapon 45 in predetermined permitted areas. The nine-axis displacement sensor in the direction sensor 21 collects acceleration data, gyroscopic data, and magnetic field data in real time. The data from the nine-axis displacement sensor of the direction sensor 21 can be processed by the microcontroller 1 using a nine-axis alignment algorithm, thus the direction of the handheld weapon 45 is calculated accordingly. 1. If the error range is out of range, the safety system 200h blocks the firing sequence of the handheld weapon 45, and thus the handheld weapon 45 cannot be fired. The vital sign detection module 20 is used to determine the presence or absence of the vital sign(s) in the direction in which the handheld weapon 45 is pointing. to actuate the actuator 3 in order to block the sequence of the portable weapon 45 when fired.

[0156] For additional security, a wireless remote control signal receiver module 14 for receiving a remote control signal from the remote controller 300H and/or a biometric/fingerprint detection module 24 may also be added.

[0157] FIG. 2.11 and 2.12 are exemplary process flow diagrams of the security system 200H shown in FIG. 2.1. For example, in FIG. 2.11 shows a schematic diagram of the process of the microcontroller 1 in the polling state, and FIG. 2.12 is a schematic diagram of the process flow of microcontroller 1, taking advantage of its interrupt handlers and processing facilities.

[0158] As shown in FIG. 2.11, the safety system 200p is started (in step S8-al) to initialize (in step S8-a2) when the target direction data is loaded, the microcontroller 1 controls the drive circuit 2 to control the lock to drive the actuator 3 with for the purpose of blocking the firing sequence of the handheld weapon 45 (at S8-a3), and thus the handheld weapon 45 is in the locked state. Subsequently, the system starts to determine whether the vital signs detection module 20 has detected the vital signs (at step S8-a4). If a vital sign(s) is detected in front of the handheld weapon 45, the microcontroller 1 controls the actuator circuit 2 to control the lock to actuate the actuator 3 to block the firing sequence of the handheld weapon 45 (in steps S8-a4 to S8 -a3). If the vital sign(s) are not detected, the security system 200h checks if the portable weapon 45 is at the assigned spatial location (at step S8-a5). Otherwise, the microcontroller 1 controls the blocking control drive circuit 2 to actuate the actuator 3 to block the firing sequence of the handheld weapon 45 (at S8-a3). If the portable weapon is at the assigned spatial location, the security system 200h continues to collect acceleration data (at S8-a6), collect magnetic field data (at S8-a7), collect gyroscopic data (at S8-a8), and calculate the direction in which the portable weapon 45 is pointing (in step S8-a9). Data about the direction in which the portable weapon 45 points is calculated using a nine-axis displacement sensor. Then, the direction data of the portable weapon 45 is compared with the direction data to the target by the microcontroller 1, and the deviation angle/range between the direction of the portable weapon 45 and the direction to the target 40 is calculated. a10) (setting from θ to 45°, which can be adjusted according to the actual situation in the field), the microcontroller 1 controls the actuator circuit 2 to control the blocking to actuate the actuator 3 to block the sequence of operation of the portable weapon 45 when fired (at step S8a3). If the error range is less than or equal to the predetermined value 9, the microcontroller controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the firing sequence of the portable weapon 45 (at S8-a11). Thereafter, the security system 200h continues to repeat the process from step S8-a3 or S8a3 onwards.

[0159] During use of the handheld weapon 45 (either in a locked or unlocked state), the wireless remote control signal receiver module 14 receives an emergency lock signal from the remote controller 300h, the microcontroller 1 of the security system 200h starts interrupt processing to perform the steps process shown in FIG. 2.12. First, the microcontroller 1 saves the current state (disabled or unlocked state) when it starts the interrupt handling process (in steps S8-b1 and S8-b2). Then, the microcontroller 1 starts interrupt processing (at step S8-b3). The microcontroller 1 checks the state whether it is in a locked state or an unlocked state (in step S8-b4). If it is in the blocked state, it remains in the blocked state and exits the interrupt processing step (at step S8-b5). If it is in the unlocked state, the microcontroller 1 checks if the fingerprints are entered correctly by the first authorized person (ie, supervisor) and the second authorized person (ie, administrator). If the leader's fingerprint is incorrectly entered, the security system 200h controls the lock control actuator circuit 2 to actuate the actuator 3 to maintain the firing sequence lock (in steps S8-b7 and/or steps S8-b8 to S8 -b5). If the fingerprints of both the first and second authorized persons have been entered correctly, the security system 200h controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock (at steps S8-b7, S8-b8 and S8-b9 ). Then the interrupt state is exited.

[0160] As can be seen, at some of the process steps as in FIG. 2.11 and/or according to FIG. 2.12, or any of these figures, processing can occur using the handler / interrupt handler of the microcontroller 1.

Combined Embodiment 2

[0161] As shown in FIG. 2.2, according to another preferred embodiment of the present invention, a security system 200i for a portable weapon 45 is provided, comprising a biometric/fingerprint recognition module 24, a GPS module 25, and a GPRS module 26. One of skill in the art will appreciate that while GPRS is shown in this exemplary embodiment, other types of wireless technologies such as 3G, 4G, 5G, or other wireless technologies may be used for the same/similar purposes. Similarly, although GPS is shown in this exemplary embodiment, a BeiDou system (BeiDou Navigation Satellite System (Navigation Satellite System BeiDou, BDS)), Galileo (or a global navigation satellite system (global navigation satellite system, GNSS)) or other positioning system. The GPS modules 25 monitor the geographic location of the man-portable weapon 45, and the GPRS modules 26 send messages or SOS signals to a remote control center. Non-GPS technology(s) may be used for the present invention and for the same purpose, including but not limited to BeiDou (BeiDou Navigation Satellite System (BDS), Galileo (or Global Navigation Satellite System (GNSS)) or other positioning system. The fingerprint recognition module 24 recognizes unique biometrics/fingerprints to unlock triggers for authorized and authenticated users.

[0162] When purchasing the portable weapon 45, the owner of the portable weapon 45 may place his or her fingers on the biometric/fingerprint recognition module 24 to capture fingerprint information to activate the security system 200i that can be attached to the portable weapon 45. Then the captured information can be sent to the remote control center server via GPRS modules 26 as part of the portable weapon registration procedure 45. Thus, the portable weapon 45 can only be used by its authenticated owner, and other persons cannot unlock the portable weapon 45. to use man-portable weapons may be predetermined by the remote control center and transmitted to the security system 200i via the GPRS modules 26.

[0163] For example, once the GPS modules 25 detect that the current geographic location of the handheld weapon 45 matches the location of the school, the security system 200i prevents it from being unlocked by the user of the handheld weapon, even if the operator is authenticated by the biometric/fingerprint recognition module 24. Conversely, if the GPS module 25 detects that the geographic location of the portable weapon 45 matches a location inside the home of the owner of the portable weapon 45, the security system 200i is configured to unlock the portable weapon 45 and the owner can use it for self-defense/or to protect their property. In authorized areas, the portable weapon 45 is typically locked in its normal state and cannot be unlocked without being authenticated by an authorized user using the biometric/fingerprint recognition module 24.

[0164] The security system 200i is mounted on the portable weapon 45. In FIG. 2.21 is an example flow diagram of the microcontroller 1 when the security system 200i enters a power down mode. FIG. 2.22 shows an example of a process flow diagram for microcontroller 1 when an interrupt is triggered.

[0165] When the security system is turned on (in step S9-al), the microcontroller 1 controls the lock control actuator circuit 2 to actuate the actuator 3 to lock the firing sequence of the portable weapon 45 (in step S9-a2). Thereafter, the security system 200i checks whether the portable weapon 45 is locked or unlocked (at step S9-a3). If it is in the unlocked state after a delay of Tic (at S9-a5), the microcontroller 1 controls the lock control actuator circuit 2 to actuate the actuator 3 to lock the firing sequence of the portable weapon 45 (at S9-a6) . If it is in the locked state or simply locked in step S9-a6, the microcontroller checks if the handheld weapon 45 has been in the locked state for more than T ₂ seconds (where T ₂ is a predetermined and preset value) (in step S9-a7). If so, the microcontroller 1 enters a power-down or sleep mode (in step S9-a8) while waiting for the wake-up.

[0166] If the user wishes to fire the portable weapon, he/she must authenticate with fingerprints in the biometric/fingerprint recognition module 24 to unlock the portable weapon.

[0167] As shown in FIG. 2.22, once the biometric/fingerprint recognition module 24 detects that a finger has been placed on the module 24, the security system 200i wakes up and performs the abort procedure (at steps S9-b1/S9-b2). The GPS module 25 receives the GPS signals and the security system 200i reads the geographic information to determine if the current position is within the authorized zone for using the man-portable weapon 45 (in steps S9-b3/S9-b4). If the detected location of the handheld weapon 45 is outside the area allowed for the use of the handheld weapon 45 (for example, in a school or public place), the security system 200i exits the interrupt routine and holds the handheld weapon 45 in a locked state (at steps S9-b4 /S9-b8). If the detected location of the handheld weapon is within the area permitted for use of the handheld weapon 45 (i.e., at the shooting range or at the owner's home), the security system 200i captures the fingerprints via the biometric/fingerprint recognition module 24 and determines whether the user's fingerprint with one of the authenticated/authorized users' fingerprints. If the fingerprints do not match, the security system 200i exits the interrupt routine and holds the handheld weapon in a locked state (at steps S9-b4/S9-b5/S9-b8). If the fingerprint matches that of the authenticated/authorized user, the security system controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the handheld weapon 45 firing sequence. The GPRS module 26 then sends this event to the remote control center for registration and security checks with the relevant authorities (in steps S9-b4/S9-b5/S9-b6/S9-b7). Thereafter, the security system 200i continuously detects the status of the portable weapon 45 (in steps S9-a3/S9-a4 of FIG. 2.21). Once it detects that the lock has been released, the security system 200 holds the unlock state for T _1c seconds (in step S9-a5 of FIG. 2.21). During this period of time T _1c, the authenticated user of the portable weapon 45 will have sufficient time to fire/use the portable weapon 45. After T _1s seconds, the security system 200i blocks the trigger to ensure safety or prevent erroneous actions (at step S9- a6).

[0168] An example system configuration for the remote control center 600 is shown in FIG. 2.23, which is a remote controller, server, or remote computer system that may include a processor 28 and its storage unit 33, a wireless communication module 27, a display 29, an audible alarm device 30, a warning light device 31, and a router 32. The wireless communication module 27 receives signals from the GPRS module 26 of the security system 200(a) mounted on the portable weapon 45. The memory unit 33 stores various dates associated with servers and databases in the remote control center 600. The display 29 displays detailed information about portable weapons 45 and security systems 200(a). When abnormal situations occur (prohibited locations for the use of man-portable weapons, signal loss, deliberate destruction), the display 29 shows detailed information. In addition, the sound alarm device 30 and warning light device 31 can be activated to give an alarm. Router 32 connects processor 28 of control center 600 to the Internet/LAN (or any type of network) 15 and provides server and database access to network equipment 16.

[0169] The network equipment 16 can access the servers and database of the control center 600 via the Internet 15, and administrators with appropriate authority can check the status of the portable weapon 45 in real time. Administrators log into the security system 200(a) and can access the database to obtain detailed information about the portable weapon connected to the control center 600, such as the type of portable weapon, date of purchase, serial number (and/or registration number, if applicable), address, information about the owner, including the name of one or more owners, address, shooter license number, if applicable, etc., trajectories, areas in which man-portable weapons 45 are found, and status as to whether whether portable weapons were intentionally/maliciously damaged/destroyed. However, ordinary users can only access their own database of weapons to check records over the Internet 15 using desktop computers or mobile phones 17.

[0170] The control center 600 may be built on Linux operating systems and Boa embedded web servers; however, one of ordinary skill in the art will appreciate that other similar or different operating systems and web servers may also be used for the same/similar purposes. The SQLite database can be installed on the ARM Linux operating system; however, one of ordinary skill in the art will appreciate that other similar or different databases may also be used for the same/similar purposes. An SQLite database can be used to store information about all active security systems 200(a), such as types of portable weapons (e.g., handguns, rifles, etc.), acquisition dates, owner names and IDs, trajectories, deliberate destruction. Using Internet devices, including mobile phones 17, Boa web servers can be accessed to check information about portable weapons in real time via the Internet 15 or wireless base stations 19. The SQLite database stores map data of public places (such as schools, churches, supermarkets, stadiums, city halls, government buildings, etc.) This information is tagged and stored in the map data.

[0171] The security systems 200(a) regularly sample the GPS data and send the GPS information to the control center 600 via the GPRS/3G module. After receiving the GPS information, the control center 600 stores the data in a database and compares the received GPS data with the location of the target public places. If the portable weapon 45 is detected in a public place, an audible alarm 30 and a warning light 31 are activated to give an alarm, and the display 29 shows information about the dangerous situation associated with the portable weapon 45. At the same time, the control center 600 also sends signals to block (or unlocking) man-portable weapons 45 via the 3G/4G module. After receiving these signals, the portable weapon 45 will be securely locked and it will be impossible to fire from it. The control center 600 may be a conventional remote controller that remotely broadcasts/sends signals to lock (or unlock) the handheld weapon 45.

[0172] Preferably, a remote controller (not shown) similar to the remote controller 300H shown in FIG. 2.1. The manager/supervisor or authorized person can control the portable weapon 45, which can be locked at any time via a remote controller. The management personnel or security service can also manage the safety of the use of portable weapons 45 at any time through the control center 600. An administrator or security authority may have greater control rights through the control center 600 than the wireless remote controller (not shown), and thus, in the event of any conflict between commands from the remote controller and the control center (600), the control center may have a higher priority (or vice versa and such settings may be configurable). Thus, the use of portable weapons 45 can be safely managed in real time in accordance with policies, regulations and actual conditions for ensuring the safety of portable weapons. After experimental testing, the control center 600 can control within the minimum delay, and such a delay can be 0.15~0.25 s (the time delay may depend, for example, on the network delay), and the time delay when controlling portable weapons is 45 from a remote controller can be about/within 0.1~0.15s.

[0173] If the control center 600 detects that the signals from the portable weapon 45 are gradually weakening (the signal level is less than the threshold value) or if the portable weapon 45 does not send signals to the control center 600, the portable weapon 45 is recognized as being in a dangerous state. Accordingly, the control center 600 sends signals to block the portable weapon 45 to ensure security.

[0174] The alarm system in the security system can be configured to detect the dismantling and deliberate destruction of portable weapons 45. In FIG. 3.1 and 3.2 show an example of a detection device MS1 for detecting such unauthorized disassembly/deliberate destruction of a portable weapon 45. The detection device MS1 comprises a lever MS11 which is operated by a button or a contact sensor MS10. The MS11 lever acts and moves in such a way that the MS11 lever does not press the MS10 button without force. When installed, the lever MS11 is pressed against the button MS10 in such a way that the lever MS11 pushes/presses the button MS10, thus indicating that the portable weapon 45, i.e. handle guard cover G2 is in place/in good condition for use; however, when the guard cover G2 is detached from the handheld weapon 45, the lever MS11 moves away from the button M10, and thus the lever MS11 releases the button MS10. As a result of this action, the security system 200(a) will detect the destruction of the portable weapon 45. When the security system 200(a) detects a malicious destruction, the security system 200(a) is configured to send control signals to the control center 600. The control center 600 registers an event and issues an alarm. To ensure the reliability of the security system 200(a), two separate GPS modules 25 are installed in the security system 200(a). Thus, the security system 200(a) is configured to function normally even if one GPS module 25 is damaged or defective.

[0175] When purchasing and activating the portable weapon 45, information about the owner is recorded and stored in the database of the control center 600. Different users with different profiles have different privileges. For example, regular users (or unauthorized users) cannot use their handheld weapons in public areas, while police officers are allowed to carry handguns and shoot when they are on duty in public places. Thus, the control center 600 determines the profile and privileges of the user and sends the appropriate signals to lock or unlock the portable weapon. Portable weapons of ordinary users are blocked in public places, while portable weapons of police officers can be freely loaded and fired from them while on duty, since police officers have higher privileges.

[0176] When the owner of the portable weapon needs to use the portable weapon for his self-defense, the security system 200(a) can immediately unlock the portable weapon so that the owner can protect himself from criminals.

Combined Embodiment 3

[0177] According to another embodiment of the present invention, a system is provided including a portable weapon security system 200j and a field controller 300j. The security system 200j is installed on the portable weapon 45 and includes a first microcontroller 1 and a radio frequency identification (RFID) electronic tag module 35 that communicates with the microcontroller 1 and/or a weapon location module 23 with a wireless communication module 27. The microcontroller 1 is connected to the drive circuit 2 for blocking control. The field controller 300j includes a beacon base station 150 and/or a control center 600 installed in a public area. Moreover, the control center 600 is the same as described above in the combined embodiment 2 implementation.

[0178] The RFID electronic tag module 35 corresponds to beacon base stations 150 that are located in public places. Wireless transmission signals will be transmitted using the free public radio frequency band, such as the 433 MHz frequency band. At present, the signal coverage radius can reach up to 300 meters. The RFID electronic tag module 35 is installed in the security system 200j on the portable weapon 45. The RFID electronic tag module 35 corresponds to the beacon signal transmission module 155, which is used to receive the transmission signal from the station. When the RFID electronic tag module 35 receives a signal from the station, the microcontroller 1 will control the lockout control actuator 2 to actuate the actuator 3 to maintain the lockout state to prevent firing in public places.

[0179] The security system 200j includes one or more unlock modules, which are devices for unlocking the portable weapon 45 by entering and confirming user information. The unlocking modules may include, without limitation, a face recognition module 36, an IC induction module, a dynamic password module, a blood oxygen and heart rate detection module, a finger vein recognition module, and a physical chip module for implementing unlocking methods. The wireless communication module 27 includes, without limitation, a GPRS module 26, a 3G communication module 34, a 4G communication module, a 5G communication module, and other wireless communication modules. The weapon location module 23 includes, without limitation, the GPS module 25. For example, for the present invention and for the same purpose, a system other than GPS can be used, including, without limitation, BeiDou (BeiDou Navigation Satellite System (BDS), Galileo (or Global Navigation Satellite System (GNSS)) or other system for determining locations.

[0180] FIG. 2.3 is an example block diagram illustrating the RFID electronic tag module 35, the GPS module 25, the 3G communication module 34, and the face recognition module 36.

[0181] FIG. 2.31 is an example of a process flow diagram of an abort initiated by the RFID electronic tag module 35. FIG. Figure 2.32 is an example of a process flow diagram depicting the operation of a system in a polling state. FIG. 2.33 is an example flowchart showing the operation of the system when an interrupt has been triggered by the face unlock module 36 . Note that the interrupt triggered by the RFID electronic tag module 35 has a higher priority than the interrupt triggered by the face unlock module 36 .

[0182] As shown in FIG. 2.32, when the security system 200j is turned on, the security system 200j starts initialization (at S10-b1), and the microcontroller 1 controls the lock control drive circuit 2 to actuate the actuator 3 to maintain the portable weapon 45 in the locked state (at step S10-b2). The security system 200j monitors the RFID electronic tag module 35 to determine whether a transmission signal has been received from the station (in step S10-b3). If the RFID electronic tag module 35 detects the specified signal, the security system 200j proceeds to an interrupt handling routine that is initiated by the RFID electronic tag module 35 (at steps S10-a1/S10-a2 of FIG. 2.31). Note that this interrupt has a higher priority than the interrupt triggered by the face unlock module 36 . The security system 200j then blocks the firing sequence of the handheld weapon 45 and then exits the abort procedure that was initiated by the RFID module 35 (at steps S10-a3/S10-a4 of FIG. 2.31). At this point, the portable weapon 45 remains blocked. If the security system 200j detects that the man-portable weapon is in a lockout state and the lockout period exceeds T2s (t≥T2s), the microcontroller 1 controls the system to go into a low power mode or a sleep mode (at steps S10-b8 /S10-b9 in FIG. 2.32).

[0183] When the face ID recognition button is pressed, the security system 200j enters an interrupt routine initiated by the face recognition unlock unit 36 (at steps S10-c1/S10-c2 of FIG. 2.33). First, the security system 200j checks whether the RFID electronic tag module 35 has received the discovery signal from the beacon signal transmission station 150 (in step S10-c3 in FIG. 2.33). If the RFID electronic tag module 35 detects a beacon signal from the station, the security system 200j exits the interrupt procedure and continues to maintain the blocking state (at steps S10-c3/S10-c9 of FIG. 2.33). Thus, it is not possible to unlock the portable weapon 45 with the facial recognition unlock module 36 in public places. If the operator with the portable weapon is at home or on the shooting range, the RFID electronic tag module 35 will not be able to receive the detection signal from the beacon signal transmission station 150 . Here, if the face unlock module 36 is triggered, the security system 200j will read the GPS data (in steps S10-c3/S10-c4 of FIG. 2.33). If the security system 200j detects that the handheld weapon 45 is outside the permitted geographic area (e.g., in various schools and public places), the security system 200j exits the interrupt stage and continues to maintain the handheld weapon in the blocking state (at steps S10-c5 /S10-c9 in FIG. 2.33). If the security system 200j detects that the handheld weapon 45 is within the permitted geographic location/area (such as the shooter's home or shooting range), the security system 200j continues to check and determines if the face recognition data entered matches the original data when the weapon is activated by the operator (in steps S10-c5/S10-c6 of FIG. 2.33). If the face recognition data matches, the security system 200j controls the lock control actuator circuit 2 to actuate the actuator 3 to unlock the handheld weapon 45. Then, the security system 200j sends the unlock information to the control center 600 via the 3G communication module 34 and registers the firing capability release information for subsequent verification by authorized personnel/officer(s). Then, the security system 200j exits the interrupt stage and enters the polling state (in steps S10-c6~S10-c9 of FIG. 2.33). The security system 200j continuously determines whether the RFID electronic tag module 35 has received detection signals from the beacon transmission station 150 . If the acquisition signal from the beacon transmitting station 150 is not detected, the portable weapon remains in the locked state (in steps S10-b3 to S10-D4 of FIG. 2.32). If the unlocked state is indicated, the security system 200j extends the unlock time by a period of time (t=T1c) during which (t=T1c) the portable weapon shooter will have enough time to fire the portable weapon, e.g. necessary defense or hunting. At the end of the period t=T1c, the security system 200j controls the lock control drive circuit 2 to operate the actuator 3 to lock the portable weapon, and is maintained in the lock state (in steps S10-b5~S10-b7 of FIG. 2.32) . When the blocking condition is detected, the security system 200j continues to detect whether the blocking period lasts for a time t that is greater than or equal to T _2s (in steps S10-b5/S10-b8 of FIG. 2.32), and the security system 200j continues to detect and execute operations as described above.

[0184] The use of face unlock module 36 is for illustrative purposes only. Accordingly, there are various other identification methods that can also be used and implemented to meet various security requirements.

[0185] For example, if using the dynamic password unlock module, the provided dynamic password does not match the original password entered when the portable weapon was activated, the portable weapon remains locked.

[0186] In another example, if using the blood oxygen and heart rate unlock module, the safety system of the present invention detects any abnormal heart rate or heart rate variability (HRV) that indicates that the person is nervous , on sympathovagal imbalance, or even on the unconscious state of a person, portable weapons will be blocked.

[0187] The method according to the embodiment effectively solves the problem of safe use of firearms in public places. These public places must have signal beacons, which must be installed in advance with the security system described herein, coupled to the station 150 transmitting the signal of the beacon. Thus, shooting in public places can be effectively controlled and prevented.

[0188] All of the aforementioned safety systems can be used alone or in combination with all trigger guards and electronically controlled firearms to form a high performance firearm trigger guard, all of which are protected by the present invention.
