Abstract: An object locating system includes a transmitter unit for activating a plurality of electronic tags to assist in locating keys, remote control devices, cordless phones, eyeglasses, articles of clothing, etc. to which the tags have been attached. The tags are self-contained, battery powered devices that signal their presence, when activated, by an audible and/or visual indication to get the attention of the user. In one embodiment for locating objects in a user's residence, a telephone interface unit responds to DTMF signals transmitted to a multi-frequency receiver over a communication link from a telephone at a location remote from or in the user's residence to produce an RF activating signal for activating a tag associated with an object to be located. The system can be used for identifying baggage, luggage, sporting equipment, and packages being dispensed from an airport baggage carousel.

Abstract: An object locating system includes at least one control unit, which is used to activate at least one electronic locator circuit to assist in locating an object to which the locator circuit is attached. The objects to be located can be a key assembly or generally any item which can be hand-carried by a person and is prone to misplacement. When activated, the locator circuit produces an audible and/or visual indication for getting the attention of the user. The locator circuit can be contained in a fob to which is attached a key, or the locator circuit can be molded into the head of a key. In another embodiment, the locator circuit is supported by a carrier which is retrofitted to a key by a securing mechanism which can include one or more fasteners, mating snap catches, or a strapping device such as a cable tie and the like. Alternatively, the carrier can be secured to the key by friction or by an interference fit between the carrier and the key.
