Method and apparatus for controlling access to a facility

摘要

The system denies unauthorized access to a locked facility by a person having a weight characteristic differing from that of the weight characteristic of the person locking a facility such as an automotive ignition system. The system comprises a method and apparatus which may be selectively activated to measure a deflection caused by a person seated in the vehicle's driver seat. The deflection is a weight information which is stored. A person subsequently seated in the vehicle seat and attempting to operate the igniton causes a second measuring operation and a comparison of the newly measured weight information with the stored information to test for a substantial parity therebetween. A substantial parity of these weights allows operation of the starting motor of a vehicle. A disparity between the weights operates a timer and/or alarm means while disabling the vehicle starter motor. The system may be used to control access to various other kinds of locked facilities such as locked rooms or buildings.
