Filed:

Dec 8, 2000

Appl. No.:

09/733195

Inventors:

Frederick A. Lee - New York NY 10012

International Classification:

F41A 1700

US Classification:

142 7001, 42 7011

Abstract:

The invention is a handgun in which the spring-loaded slide is replaced by an electric motor, engageable only upon an authorized user entering an access code. A combination rechargeable battery and keypad engages the butt of the handle where the magazine well is located and includes an electrical plug the fits into the handle, making an electrical connection between the battery and a microprocessor in the handgun. Entering the proper code on the keypad allows the microprocessor to complete the circuit between the battery and a motor that actuates the slide. When the device is not in use, the magazine having been removed, the motor then moves the slide rearward, ejecting any cartridge in the chamber, and maintains the slide in a position where the chamber is always open, thereby making obvious to anyone that the gun is not loaded.

International Classification:

H04N 718

US Classification:

348144

Abstract:

An aircraft surveillance and recording system adapted to monitor conditions prevailing in the course of a flight and provided for this purpose with video cameras placed at different sites on the plane. The output signals yielded by the video cameras are fed to an on-board radio-frequency transmitter to modulate a radio-frequency carrier that is radiated from the plane and intercepted by an active communication satellite. The satellite relays the signals to a ground recording station whose stored recording of the real time images from the cameras is available to investigators should an accident or other incident occur in the course of the flight. The system includes at least four video cameras, the first of which has an audio function and is trained on the flight crew in the cockpit of the plane. The second video camera is focused on the instrument panel and controls in the cockpit. The third camera which has an audio function looks into the passenger cabin, while the fourth camera is mounted on top of the aircraft rudder to observe exterior surface control movements, such as those of flaps, ailerons and elevators.

Appl. No.:

Inventors:

Frederick A. Lee - New York NY

International Classification:

B62D 2100

US Classification:

280 801

Abstract:

An automobile having a pair of front wheels and a pair of rear wheels provided with run-flat tires. The front tired wheels which are steerable are driven through a power transmission by an engine housed between these wheels. The tired front wheels are relatively narrow in width to make room for a large engine and are relatively large in diameter to afford a more favorable power transmission ratio and improved steering control. The tired rear-wheels are broad in width and small in diameter to enhance the tire-to-road surface area for more effective braking and to allow for an enlarged trunk capacity.
