Abstract: Apparatus for sensing and transmitting physical intelligence is disclosed. In one embodiment the intelligence is transmittable from the sensing device to a remotely positioned, intelligence processing unit. The apparatus taught has particular applicability to gas turbine engine control systems requiring the encoding and transmission of accurate physical intelligence from a hostile environment to the remotely positioned intelligence processing unit. Techniques employing time sequencing through a fiber optic circuit of the transmitted intelligence to reduce the size, weight and complexity of the apparatus are developed.
