Patent ID: 8600578

Claim:
A system for preventing unauthorized operation of an automobile with an automobile engine which comprises: a transmitter means locatable with an operator, for broadcasting a start signal from said transmitter means, initiated by said operator wherein said transmitter means comprises: a power supply ( 10 ) for providing direct current voltage; an oscillator circuit means ( 15 ) for generating a start signal when said oscillator circuit ( 15 ) is coupled to said power supply ( 10 ); a start switch connected between said oscillator circuit and said power supply wherein said oscillator generates said start signal when said start switch is closed; an antenna means ( 17 ), coupled to said oscillator means ( 15 ) arranged for broadcasting said start signal; and said system comprises: a receiver means, locatable with said automobile engine, for generating resonant energy when said receiver means receives said start signal wherein said receiving means comprises: a receiving antenna ( 20 ) arranged for receiving said start signal from said oscillator; a tank circuit means ( 23 ) coupled to said receiving antenna ( 20 ) and arranged for providing that said tank circuit means ( 23 ) generates a resonating signal in response to receiving said oscillator signal; a rectifier means ( 28 ) coupled to said tank circuit ( 23 ) for converting said resonating signal to a direct current (d.c.) starter signal; and said system comprises a clutch means ( 45 ) coupled to said rectifier means ( 28 ) for coupling said starter to a drive shaft of said engine when said drive shaft of said engine is turning below a critical rate and decoupling said starter motor from said drive shaft when a rotational rate of said drive shaft is greater than said critical rate.
