ABSTRACT:
Devices for enabling a user to locate an object, animal or person or reminding the user of the location of an object, animal or person. In a non-transmitter/receiver embodiment, the device includes at least one alert mechanism which is connected to a digital clock or other timer and microprocessor which times transmission of alert signals emitted from the alert mechanism or mechanisms. The operational components of the device may be contained in a housing which is attached to the object, animal or person to be located. In a remote transmitter/receiver embodiment, the device includes a transmitter which transmits activation signals at preset times to activate an alert feature of a paired remote receiver which is provided on the object, animal or person to be located or tracked. The transmitter may include an on-command button for manual transmission of the activation signals to the receiver. The receiver may have a visible alert mode in combination with a selected audible or vibratory alert mode. In an on-board transmitter/receiver embodiment, the device includes a transmitter which is housed together with a receiver in a single unit. In that case, the transmitter of one unit can transmit preset timed activation signals to the receiver of a different unit which is placed on the object, animal or person. Alternatively, the transmitter of one unit can transmit preset timed activation signals to the receiver of the same unit placed on the object, animal or person.
