Adaptive wireless torque measurement system and method

A method for installing a wireless torque measurement system, the method comprising the steps of:

• coupling a rotor antenna to a rotor;
• disposing a stator antenna in proximity to the rotor antenna to thereby inductively couple to the stator antenna and the rotor antenna;
• receiving, via the rotor antenna, power signals transmitted by stator electronics;
• using rotor electronics to (i) determine the power level magnitude of the power signals, (ii) generate feedback data with a bit resolution that is based at least in part on the determined power level magnitude, and (iii) transmit, via the rotor antenna, the feedback data;
• and
• adjusting the proximity of the stator and rotor antenna to achieve a desired bit resolution in the feedback data.

An adaptive wireless torque measurement system comprising:

• a rotor;
• a flat coil rotor antenna attached to the rotor;
• a flat coil stator antenna configured to be inductively coupled to the rotor antenna;
• stator electronics coupled to receive, via the stator antenna, feedback data and configured, in response thereto, to generate and transmit, via the stator antenna, power signals at a power level magnitude based in part on the feedback data;
• and
• rotor electronics attached to the rotor and coupled to receive, via the rotor antenna, the power signals transmitted by the stator electronics, the rotor electronics configured to:
• (i) determine the power level magnitude of the power signals,
• (ii) generate the feedback data with a bit resolution based at least in part on the determined power level magnitude, the feedback data at least including information representative of the determined power level magnitude, and
• (iii) transmit, via the rotor antenna, the feedback data.
