Access control module for a personal computer

摘要

A retrofitted personal computer ("PC") has an access control module attached to the rear wall of the PC. A secondary switch within the access control module is connected in series between the main switch of the PC and the power supply. An authorized user remotely controls the powering of the PC by turning "ON"-"OFF" of the secondary switch through the "ON"-"OFF" radio pre-coded transmitter. The disk drive of the PC is protected by a disk drive lock, which is interconnected with the access control module and the PC by a cable.
