Abstract:
Weight sensing anti-theft vehicle system comprising:a weight sensor means for sensing the weight of a driver seated in a driver's seat of a vehicle, said weight sensing means being mounted to a driver's scat of the vehicle, said weight sensor means producing a weight signal corresponding to the wright sensed by said weight sensor means; a microprocessor means connected to said weight sensor means for controlling the running of and shutting off an engine of a vehicle; and an ignition means for selectively preventing the starting of an engine of the vehicle and for selectively stopping operation of the engine of said vehicle, the ignition means being connected to said microprocessor means; wherein said weight sensor means includes a mat having a plurality of weight sensors connected to and dispersed throughout said mat, said mat being disposed in the driver's seat of the vehicle said weight sensor means being connected to said microprocessor means for sending said weight signal to said microprocessor means; wherein said microprocessor means includes a microprocessor unit connected to said mat and a memory circuit connected to said microprocessor unit for storing weights of persons authorized to operate the vehicle and a preprogrammed access code assigned to each of the persons authorized to operate the vehicle, and also includes a keypad data entry device connected to said microprocessor unit, said keypad data entry device being mounted in a passenger compartment of the vehicle for permitting entry of the weight of a person authorized to be a driver of the vehicle and the preprogrammed access code to be detected by said microprocessor unit, said microprocessor unit stopping operation of the engine of a vehicle through said ignition means if said weight sensing means discontinues sending said weight signal to said microprocessor means and indicating that the driver has moved from the driver's seat of said vehicle; and a power source connected to said microprocessor unit.
