Arrangement for wireless signal transmission from a rotating body to a stationary receiving station
First Claim
1. An arrangement for wireless signal transmission from a rotating body to a stationary receiving station comprising a current supply unit at least partly incorporated within the rotating body, the rotating body further comprising a receiving unit for receiving signals from a stationary transmitting station, a signal processing unit, a high precision sensor unit for detecting infinitesimal changes of working conditions of an item carried by said rotating body, and a transmitting unit for transmitting signals to the receiving station, the signal processing unit being operatively connected to the sensor unit and the receiving and transmitting units respectively, for causing the issuance of the output signal of the transmitting unit as a result of the input signal of the receiving unit.

Abstract
A rotating body, for example a chuck (10) comprises a sensor (56), a signal processing unit with amplifier and a plurality of transmitting diodes (14) and receiving diodes (16) peripherally spaced in a radial plane, in which also a stationary transceiving station (18) is arranged. The sensor (56) detects special working conditions of a tool clamped in the chuck (10). Signals of sensor (56) are fed to the signal processing unit. Sense commands transmitted from the transceiving station (18) via receiving diodes (16) are processed in the processing unit during rotation of the chuck (10) and corresponding working condition signals are transmitted from the transmitting diodes (14) back to the transceiving station (18).
