ABSTRACT:
An infrared communicating badge is provided for transmitting an infrared coded signal, such as a patient identification number. The badge includes a sealed housing having an infrared transparent segment. The badge housing contains a power source, a microprocessor, an infrared transmitter, and an infrared receiver. The badge receiver is desensitized such that it does not respond to ambient light from the surroundings and, preferably, only detects signals from a programmer. This programmer transmits a coded infrared signal, which represents the patient identification number, to the badge. After the coded infrared signal is transmitted and stored in the badge, the infrared signal is transmitted periodically to another infrared receiver, located in a remote location. The remote receiver relays the information to a base unit at which the location of a person may be monitored.
