Abstract
A portable proximity alert detector is provided for a user to determine when at least one companion comes within a predetermined range of the user. The device includes a receiving portion for wirelessly receiving a first signal encoded with a code identifying a companion and a transmitting portion for wirelessly transmitting a second signal encoded with a user identifying code. The device also includes a processor, a modulator operationally coupling the processor to the transmitting portion for modulating the user identifying code, and a demodulator operationally coupling the processor to the receiving portion for demodulating the companion identifying code. A first memory segment is operationally coupled to the processor for storing companion identifying codes received by the receiving portion. A second memory segment is operationally coupled to the processor for storing companion identifying codes of companions whom the user desires to contact. A third memory segment operationally coupled to the processor for storing the user identifying code. A user interface is operationally coupled to the processor through which the companion identifying codes of the companions whom the user desires to contact are programmed into the second memory segment. An indicator is provided for alerting the user when at least one companion identifying codes received by the receiving portion matches one of the companion identifying codes stored in the second memory segment.
