Abstract
A personal infrared beacon unit capable of being worn as an adornment of clothing, incorporated into a part of a person's attire, or embodied within a personal pager, a cellular phone or a 2-way data device. The beacon unit may be in communication with an established network and may be activated externally by a locator signal, or internally by activation of an emergency button. Upon activation, the beacon unit emits coded timed infrared bursts in coherent beams, and when the beams are detected, they may be decoded visually or with a decoding device to provide the identity and location of the user.
