Development of Coordinate Measuring Equipment Using Electromagnetic Give and Receive Action Method
Murakami, Yamamoto Yamamoto, Yamanami · 1988
We designed a new coordinate measuring equipment that uses the LC resonant circuit. The pointing devices of this equipment have no cords and no batteries and dose not directly contact the sensor board. It can measure coordinates at an accuracy of up to 0.1mm and also detect the state of the switch.
