ABSTRACT:
A motion sensing device which includes a means including a light source for sympathetic movement with the motion, a light responsive fluid contained in a resilient envelope contiguous to the light source to receive light from the source for either absorption or fluorescence illumination, and photo-responsive means contiguous to the resilient envelope to provide electrical output of the light absorption or fluorescence variations which are inversely or directly proportional, respectively, of said motion.
