Abstract:
1. A system for reading and monitoring a rotating disk, comprising: an adhesive material applied to a portion of the rotating disk that is less than the circumference of the disk and having at least one highly reflective section and at least one substantially non-reflective section so as to produce contrasting sections of reflective material and non-reflective material on the adhesive material; an optical sensor configured to produce a first output corresponding to detections of the highly reflective section of the adhesive material and a second output corresponding to detections of the substantially non-reflective sections of the adhesive material; a processor coupled to the optical sensor configured to interpret the outputs produced by the optical sensor; and a transceiver coupled to the processor for transmitting data to a remote location.
