User programmable portable proximity detector
First Claim
1. A proximity alert device comprising:
- an interface that receives a first identity code, wherein the first identity code is associated with a user associated with a second proximity alert device;
a memory that stores the received first identity code, the stored first identity code being in a data structure associated with one or more persons about whom a user of the proximity alert device wishes to know a proximity;
a receiver that wirelessly receives a second identity code and location information associated with a location of the second proximity alert device;
a processor that executes coded instructions that compare the received second identity code to the stored first identity code; and
an indicator that automatically outputs an alert if the received second identity code matches the stored first identity code, and if the second proximity alert device is within a predetermined distance of the proximity alert device, wherein the alert comprises an identification of the user associated with the second proximity alert device.

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.

7. A method comprising:
-
receiving, into a first proximity alert device, a first identity code, wherein the first identity code is associated with a user associated with a second proximity alert device;
storing the received first identity code in a data structure associated with one or more persons about whom a user of the first proximity alert device wishes to know a proximity;
wirelessly receiving, into the first proximity alert device, a second identity code and location information associated with a location of the proximity alert device;
comparing the received second identity code to the stored first identity code; and
automatically outputting an alert if the received second identity code matches the stored first identity code, and if the second proximity alert device is within a predetermined distance of the first proximity alert device, wherein the alert identifies the user associated with the second proximity alert device. - View Dependent Claims (8, 9, 10, 11, 12)
