Abstract
Abstract Each of a plurality of data modules employing commercially available microprocessor circuitry, process pulse rate information from a plurality of remote monitors to develop a digital indication of a desired parameter, i.e., radiation level. A digital check module, incorporating microprocessor electronics comparable to that of the data module, scans the respective data modules to determine the operational integrity of the data modules and automatically assumes the operational responsibility of a data module determined to be operating improperly.
