Devices for locating/keeping track of objects, animals or persons

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.

System and method of silent alarm

A system and method of providing a silent alarm is provided for tactilely alerting a user. The system includes a timekeeping device having a timekeeping mechanism for tracking real time, an input mechanism operatively connected to the timekeeping mechanism for setting an alarm time, a processor operatively connected to the timekeeping mechanism that monitors the real time and the alarm time, and a wireless data transmitter operatively connected to the processor, such that the wireless data transmitter transmits a signal at a predetermined radio frequency when the real time corresponds to the alarm time. The system also includes a silent alarm signaling device secured to a user, wherein said silent alarm signaling device includes a wireless data receiver, a processor operatively connected to the wireless data receiver, and a signaling mechanism operatively controlled by the processor. The method includes the steps of the user initializing the alarm time for the timekeeping device using the input mechanism, comparing the alarm time to the real time, activating a silent alarm if the alarm time corresponds to the real time by transmitting a predetermined radio frequency signal from the wireless data transmitter to the wireless data receiver, processing the signal using a microprocessor operatively connected to the wireless data receiver, and activating a signaling mechanism to provide the user a tactile alarm.
