Spindle mounted telemetry system
First Claim
1. In combination with a spindle having a hub rotating on bearings and coupled to a rotating member, a telemetry assembly coupled to the spindle, the telemetry assembly comprising:
- a wireless transmitter coupled to the hub to rotate therewith;
a receiving antenna wirelessly coupled to the transmitter; and
a guiding system coupled to the wireless transmitter and the receiving antenna to guide rotation of the wireless transmitter relative to the receiving antenna, the guiding system having a central aperture through which at least one of the spindle and the rotating member extends.

Abstract
The present invention relates to a telemetry assembly for a spindle. The telemetry assembly includes a wireless transmitter coupled to the spindle to rotate therewith and a receiving antenna wirelessly coupled to the transmitter. A guiding system having a central aperture and coupled to the wireless transmitter and the receiving antenna guides rotation of the wireless transmitter relative to the receiving antenna. If desired, the telemetry assembly can be used in a telemetry system including a hub adapter mountable to the spindle and a transducer mountable to the hub adapter. Furthermore, an angular positioning device and a wireless power coupling can be provided.
