ABSTRACT:
A security system (300) for a personal computer maintains computer terminal (302) in an active mode of operation while the user is within range of the terminal. The system includes a radio (314) worn by a user (316) which generates a low level RF signal (318). As long as the user (316) remains within range of the computer (302), a receiver (312) will detect a received signal strength which maintains the computer monitor (306) in an active mode of operation. When the user (316) walks away from the computer terminal (302), the received signal strength decreases below a threshold which causes the monitor (306) to go into a lock-out condition.
