Abstract
The disclosure describes a security system for motor driven vehicles and motor operated plants which uses a micro-chip that is mounted inside vital motor accessories and prevents these accessories from operating without the entry of a 4-digit code word. The micro-chip consists of a silicon substrate and an added semiconductor-switch that adapts the micro-chip to the various switching requirements of the various types of motor accessories. The silicon substrate carries all circuitry for data entry, data storage, conparison, evaluation and control functions and is designed to store data without power. Special circuits are provided to adapt the unit to a number of service requirements, such as maintenance, automatic code entry, and erasure of forgotten codes.
