    Abstract: An absolute value encoder for sensing the number of revolutions, wherein an A-phase/B-phase generating section (610) generates A-phase/B-phase one-period pulse signals the phases of which are 90 degrees different from each other within one revolution of the shaft on the basis of the light passing through a slit rotating together with the shaft. When an A-phase/B-phase status sensing section (640) senses a change of the pulse signals, a clock generating section (66) switches the clock frequency.

    Abstract: An optic speed sensor for sensing the speed of a rotating component such as a gear includes a sensor such as an electromagnetic speed sensor disposed in proximity to teeth of the gear. Within the housing of the sensor are one or more electrical signal lines having electrical signals imposed thereon, the electrical signals being indicative of the rotational speed of the gear. Physically connected to the sensor housing is a mating connector. Disposed within the housing of the mating connector are corresponding one or more LEDs, each LED being electrically connected to the electrical speed signals provided by the sensor. Each LED provides an optical signal indicative of the speed of the gear, each LED having fiber optic cable connected thereto which transmits the optical energy output by the associated LED to an optical receiver disposed away from the sensor, such as a control unit for the device incorporating the gear. The optical receiver transforms the optical signal into a form, such as to an electrical signal, more suitable for the type of signal processing performed at the predetermined location.
