Abstract: A locking firearm holder that can be mounted in a vehicle; the holder employs a capture lever to lock or grip against the trigger guard of a firearm, such as a hand gun. The holder exhibits two stable states: a capture lever lock state or a capture lever unlock state. The method of switching between these two stable states is the same in either case: the user pushes against the firearm, along the axis of the firearm. This initial action by the user either locks the firearm in place, or unlocks the holder to allow the user to withdraw the firearm from the holder. The holder includes a withdrawal limiter to prevent premature re-locking as the firearm is being released. The holder includes a lock tab positioned near the locked firearm; the lock tab must be actuated to unlock the holder, thus preventing an accidental unlocking due solely to vibration.

Abstract: A laser receiver detects a thin beam of laser light and distinguishes between the beam of laser light and an omni-directional pulse of light from a strobe by the use of an additional photo-detector. The device takes into account the possibility that the additional photo-detector could be illuminated simultaneously with the main photo-detectors at the end of the main photo-detectors closest to the additional photo-detector.

Abstract: A printed circuit board motor is disclosed. The motor comprises a rotor plate embedded with magnets, an axle, and a printed circuit board stator. The printed circuit board comprises two conductors printed on the same surface or on opposite surfaces of the printed circuit board The two conductors produce alternating “square wave” patterns. The printed circuit board circuitry causes the direction of the current flow to reverse at intervals. The rotor rotates in response to the current flow in the stator. The rotation rate can be accurately controlled. The torque and average current consumption can be controlled by “chopping” the current with high frequency modulation whose duty cycle is proportional to the torque and average current consumption which will prolong the battery life of the motor.
