    Abstract: A high signal to noise ratio circuit and signal processing scheme described herein provides signal power above a noise floor such that high performance rate gyro operation can be achieved. The technology described herein exploits the combination of very low noise rate signal front end and a carrier frequency locked to a crystal filter's passband. A fixed single frequency and a sampled alternating current amplitude for conveyance of rate information is utilized.

    Abstract: In a telemetry system (100) in a high-temperature environment of a combustion turbine engine (10), a wireless power-receiving coil assembly (116) may be affixed to a movable component (104) of the turbine engine. Power-receiving coil assembly (116) may include a radio-frequency transparent housing (130) having an opening (132). A lid (134) may be provided to close the opening of the housing. Lid (134) may be positioned to provide support against a surface (120) of the movable component. An induction coil (133) is disposed in the housing distally away from the lid and encased between a first layer (136) and a last layer (140) of a potting adhesive. Lid (134) is arranged to provide vibrational buffering between the surface (120) of the movable component (104) and the layers encasing the induction coil.
