Abstract

A processor having a timer relay and a comparitor relay interprets, stores and compares inputted biometric data with pre-loaded biometric data and responds including activation of a vehicle'"'"'s electronic systems. An electronic system interrupter allows the vehicle'"'"'s electronic system to function with the interrupter maintained in the electronic systems functioning position by a signal from the processor thereby allowing the interrupter to be overridden by the processor to keep the electronic system in a functioning mode. An air pressure sensor detects the vehicle'"'"'s speed and signals when speed is beyond a preset threshold. The processor, the input device, electronic system interrupter, air pressure sensor and a power source are electronically coupled.

Claims

1. An aircraft anti-theft system for preventing unauthorized personnel from starting an aircraft without both human and data code and with safety features that allow restarting following an in-flight stall comprising, in combination:

a starter assembly electronically coupled to an aircraft engine having both an enabled state and a disabled state the starter assembly further including a starter solenoid;

an identity/authorization reader being adapted to collect definable human characteristic and to collect authorization data from a potential user prior to starting an aircraft and adapted to compare said collected authorization data with stored user human characteristic data and authorization data, said authorization data being stored on at least one of the magnetic strap cards, and chips;

an air pressure sensor adapted to signal if the aircraft is in motion beyond a preset threshold, including a pitot or air collecting tube or source attached to the aircraft and further including a relay switch;

a power source adapted to provide power to the system, including a power switch; and

a processing unit comprised of a timer relay including a pair of switches and an inductor, and a comparator relay, including a pair of relay switches, said processing unit being electrically coupled to the starter assembly, said processing unit and said identity/authorization reader and said air pressure sensor and said power source, with the processing unit being adapted to put the starter assembly in the enable state upon receipt of the authorized identity and authorization reader input so that once the identity is authorized, the identity/authorization reader returns the aircraft back to normal starting configuration for activating said aircraft said identity/authorization reader is inactivated, when the air pressure sensor is activated by the aircraft exceeding a threshold speed and the starter assembly remains in the enabled state, ensuring that while in-flight the aircraft can be restarted without having to activate said identity/authorization reader, only when the aircraft master switch has been de-energized will the processing unit require the activation of said identity and authorization reader before the starter assembly will again be put into the enabled state.
