USER PROGRAMMABLE PORTABLE PROXIMITY DETECTOR
First Claim
1. A portable proximity alert detector for a user to determine when at least one companion comes within a predetermined range of the user, comprising:
- a receiving portion for wirelessly receiving a first signal encoded with a code identifying a companion;
a transmitting portion for wirelessly transmitting a second signal encoded with a user identifying code;
a processor;
a modulator operationally coupling the processor to the transmitting portion for modulating the user identifying code;
a demodulator operationally coupling the processor to the receiving portion for demodulating the companion identifying code;
a first memory segment operationally coupled to the processor for storing companion identifying codes received by the receiving portion;
a second memory segment 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 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; and
an indicator 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.

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.

13. A method for determining when at least one companion comes within a predetermined range of a user, said method comprising the steps of:
-
storing an identification code of each companion whom the user desires to contact;
receiving over a wireless communication link a first signal encoded with a code identifying a companion;
transmitting over a wireless communication link a second signal encoded with a user identifying code;
comparing said received companion identifying code with said stored identifying codes; and
alerting the user when said received companion identifying code matches one of said stored identifying codes. - View Dependent Claims (14, 16, 17, 18, 19)
