Abstract
A personnel monitoring apparatus has a transmitter for transmitting a data encoded signal. A strap is provided for coupling the transmitter to a person to be monitored. An emitter is attached to the transmitter for emitting an optical signal. A detector is attached to the transmitter for detecting the optical signal. An optical fiber is incorporated with the strap for optically coupling the emitter and the detector. A comparator compares the optical signal and a reference signal, and the result of the comparison sets the value of a preselected data bit in the data encoded signal.
