US 6,686,840 B1 · Personal security alarm system

Abstract

A personal security alarm system includes transmission and alarm housings. The transmission housing includes a transmitter connected to control buttons for selectively sending alarm or range signals. The alarm housing includes a receiver, CPU, alarm, and a mode switch. In automatic mode, the receiver receives continuous range signals from the transmitter and the CPU energizes the alarm if the range signals are not received. In alarm mode, the CPU energizes the alarm if the receiver receives a predetermined alarm signal. The alarm housing may be coupled to a quick-connect attachment of a purse. The purse includes an electro-mechanical locking assembly that may be energized by the CPU. The purse may be locked upon a sensed theft attempt or by a user pressing a control button on the alarm housing.
