Abstract
A voice-activated location system comprising a transmitter unit and a receiver unit coupled to a frequently misplaced item. The transmitter unit receives an audible sound, generates an analog signal corresponding to the audible sound and transmits a coded radio frequency ("RF") carrier signal upon recognizing that the audible sound represents a voice command. The carrier receives the coded RF carrier signal, decodes the coded RF carrier signal to produce a serial bit stream. The serial bit stream is compared with a digital code associated with the receiver unit. If there is a match, the receiver unit emits an audible sound for a predetermined time period to assist in locating the item.
