摘要: An absolute encoder monitors rotary position and senses rotary displacement relative to a measuring scale. The absolute encoder evaluates rotary displacement by providing a plurality of rotatably mounted encoder wheels, and each wheel includes at least one code sequence which in combination comprises the measuring scale. A pinion is provided between each pair of encoder wheels in order that each of the encoder wheels will be rotated upon the rotation of the shaft. Each code sequence of the encoder wheel is monitored by a sensing mechanism and this information is utilized to evaluate the shaft position. The sensing mechanism includes both light emitting and light detecting devices which monitor a defined region of each code sequence and this is evaluated in determining the rotary position.

摘要: A verification system monitors the operation of a digital control system in order to insure proper operation. The verification system receives control signals and monitors these control signals to determine whether operation is proper. The digital control system is adapted for operational control of various equipment. The verification system monitors control signals received from the digital control system as well as the status of the equipment, where appropriate, in determining whether the operation of the digital control system is proper. The verification system includes various portions which monitor the control signals at various stages. If there is an error detected at one of the stages, an error signal is generated which prevents operation of the associated equipment.
