  • Position measuring system
    Patent number: 4419012
    Abstract: A position measuring system comprising a transmitter (5, 19) mounted on one body and arranged to direct a flashing beam of radiation onto an area sensor (11) which is mounted on the other body and forms part of a receiver arranged to produce an output indicative of the position of impingement of the beam on the sensor from samples of the radiation impinging on the sensor when the beam is on and off, the receiver including a second sensor (31) responsive to the radiation beam whose output synchronizes the operation of the receiver to the flashing beam. The requirement for a physical connection between receiver and transmitter to synchronize the receiver with the flashing beam is thereby avoided.
