RADIO FREQUENCY OBJECT LOCATOR SYSTEM

摘要

An object location system having tags (14) for tracking objects. A finder (12) and tags each have a memory (16, 64), and RF send (20, 60) and receive (22, 62) capabilities. The finder stores tag identification codes in its memory, and associates the tag identification codes with descriptive text identifying an object to a user. A user selects (18, 26) a descriptive text identifier to locate an object, and the finder transmits a search RF signal including the tag identification code to locate the tag attached to the desired object. The tags receive the search RF signal and, if the transmitted identification code matches an identification code stored in a given tag, that tag responds by transmitting a found RF signal. The finder then indicates (34, 40) to the user a relative proximity of the finder to the object.
