ABSTRACT:
An object location system having tags for tracking objects. A finder and tags each have a memory, and RF send and receive 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 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 compare the transmitted tag identification code with their own stored identification codes. A tag responds to the finder by transmitting a found RF signal if the transmitted and stored tag identification codes match. The finder signals to the user that the object with the selected descriptive text identifier has been located, and indicates a relative proximity of the finder to the object.
