Abstract: A noise cancelling system is described for a in a patient implantable hearing implant system. An implantable microphone senses a sound signal present at the microphone that includes a sound source component from a sound source external to the patient, and a noise component from internal bone conduction. At least one implantable noise sensing element is located near the microphone to sense the noise component. A filter is controlled by an adaptive algorithm responsive to transform the noise component and outputs a transducer control signal. A bone conduction transducer receives the transducer control signal and generates a corresponding mechanical vibration signal to the skull bone. The adaptive algorithm controls the filter so that the mechanical vibration signal of the bone conduction transducer offsets the noise component sensed by the at least one noise sensing element so as to minimize the noise component sensed by the implantable microphone.

Abstract: An implant includes a humidity sensor for generating a signal indicative of humidity within the implant. A controller within the implant receives the signal indicative of humidity, and controls the implant based on the signal indicative of humidity.

Abstract: A signal processing arrangement for a cochlear implant system is described. A sensing microphone senses an acoustic signal to generate a corresponding electrical sound signal. An information detection circuit performs spectral analysis on the sound signal to identify the presence of speech information. A sound signal processing circuit generates an implant communications signal for the cochlear implant system based on the sound signal, and has an energy saving operational mode wherein the implant communications signal is generated only when the information detection circuit identifies that speech information is present in the sound signal.

Abstract: An arrangement is described for a partially implantable medical system. A communications coil is adapted for placement parallel to a corresponding partner coil for communication of an implant communications signal having an associated magnetic field component. An implant electronics module is adjacent to the communications coil and electrically connected with it for coupling of the communications signal. And a planar coil shield lens is between the communications coil and the electronics module to promote coupling of the communications signal between the coils and to shield the electronics module from interaction with the magnetic field component.

Abstract: A system and method are described for an implantable sensing system. An implantable sensor generates a sensing signal representative of an internal sensing location of a user. A sensing gate, coupled to the sensor and responsive to the sensing signal, has a sensing gate threshold value such that the sensing signal is coupled from the sensing gate to an implanted signal processor when the sensing signal has a magnitude greater than the sensing gate threshold value, and the sensing signal is blocked when the sensing signal has a magnitude less than the sensing gate threshold value.
