Abstract

In methods and apparatus for operatively coupling a radiant energy/electric current transducer to an electric current processor, a removable coupling module is provided for insertion between that processor and that transducer. A memory integrated circuit is provided in that coupling module. Information about the transducer relevant to operation of the processor is stored in that memory integrated circuit. A processor connector plug is on the removable coupling module for the memory integrated circuit. The coupling module is separable from the processor at that processor connector plug. A transducer connector plug is on the removable coupling module. The transducer is separable from the coupling module at that transducer connector plug, wherein the transducer is separable from the coupling module and that coupling module is separable from the processor. During operation of the transducer, the stored information is obtained with the processor from the memory integrated circuit in the coupling module, and the processor is operated pursuant to that obtained information to process electric current for the transducer.
