  • Linear position transducer with wireless read head
    Patent number: 7971487
    Abstract: A linear position transducer reliably and wirelessly tracks rapid motion. The transducer includes a scale, a control head, and a wirelessly-powered read head disposed proximate to the scale. The read head is configured to sense movement between the scale and the read head and to wirelessly communicate position data to the control head. The control head can include a wireless data receiver to receive position data from the read head, an output data driver to communicate with an external device, and a microcontroller to coordinate a data transfer between the wireless data receiver and the output data driver. In addition, the read head can include a wireless data transmitter to transmit position data to the control head, a linear position sensor to sense position along the scale, and a microcontroller to calculate a position measurement from the scale. The microcontroller in the read head can also coordinate a data transfer between the wireless data transmitter and the control head.
