Abstract: A gun locking and unlocking device, which may be configured to be disposed adjacent the trigger of a gun to alternatively prevent or enable firing, includes a data receiver, a data memory and a logic device for determining whether data received by the receiver is the same, or substantially the same, as data stored in the data memory. One or more separate electronic gun keys are provided to transmit gun lock/unlock data to the data receiver of the gun lock device. The logic device responds to a gun control signal transmitted by one of the gun key devices with priority over a gun control signal transmitted by another gun key device. The logic device automatically locks the gun when it is located in a prohibited area, such as a school. The logic device also locks the gun when the gun user is intoxicated or acting in an irrational manner. Once locked, the user must set a timer which allows the gun to be unlocked only after a specified “wait” time.

Abstract: A gun trigger-looking device which is configured to be manually installed on a gun with a trigger-blocking member disposed behind the trigger to prevent the gun from being fired. The device includes a data receiver, a data memory and a logic device for determining whether data received by the receiver is the same as data stored in the memory. If a data match is indicated, the logic device causes an electromagnetic device to move a locking member to an unlocked position, permitting the trigger-blocking member to be manually removed from the gun so the gun can be fired. A separate electronic key is provided to transmit unlock data to the data receiver of the trigger-locking device. This unlock data may be a password, a long pseudo-random number or biologic data identifying the gun owner or some other person who is licensed or otherwise authorized to fire the gun.

Abstract: A battery-powered trigger-locking device, which is configured to be disposed on a gun with a trigger for firing, includes a data receiver, a data memory and a logic device for determining whether data received by the receiver is the same, or substantially the same, as data stored in the memory. If a data match is indicated, the logic device causes an electromagnetic device to move a trigger-locking member to an unlocked position, permitting the gun to be fired. A separate electronic gun key is provided to transmit gun unlock data to the data receiver of the trigger-locking device. This gun unlock data may be a password, a long pseudo-random number or biologic data identifying the gun owner or some other person who is licensed or otherwise authorized to fire the gun.

Abstract: A battery-powered electronic evidence-collecting device on the gun that transmits to a smartphone or other device carried by the peace officer for recording and forwarding the evidence to a central station. The evidence collecting and recording apparatus is activated by the removal of the gun from its holster.

Abstract: An STOL and/or VTOL aircraft comprises (1) a fuselage having a front end, a rear end and two lateral sides, the fuselage defining a substantially horizontal central longitudinal axis of the aircraft; (2) an aircraft tail arranged at the rear end of the fuselage and including a rudder and an elevator on each side of the fuselage with movable surfaces for controlling the aircraft; and (3) a wing on each side of the fuselage having a front edge, a trailing edge and an upper surface extending from the front edge to the trailing edge. A device for controlling the airflow over the upper surfaces of the wings comprises openings in these upper surfaces for the egress of air from interior spaces within the wings and air pump apparatus for pressurizing such interior spaces.

According to the invention, a device is provided for increasing the speed of an airstream flowing over the upper surfaces of the wings as compared to the speed of the airstream flowing over the lower surfaces thereof. Such means comprise openings in the upper surfaces of the wings for the egress of air from interior spaces within the wings and air pump apparatus for pressurizing such interior spaces.

Abstract: A method and apparatus are disclosed for treating fuel to temporarily reduce its combustibility, and thereafter restore its combustibility. As used in an aircraft, the method comprises the following steps: (a) treating aircraft engine fuel to substantially reduce its combustibility in open air; (b) carrying the treated fuel in a fuel tank of an aircraft; (c) increasing the combustibility of a portion of the treated fuel, as needed by the aircraft engine; and (d) supplying the increased restored combustibility fuel to the aircraft engine. Using this method, the preponderance of the fuel on board the aircraft is maintained at low combustibility for safety.
