Abstract: A signal processor is described for communication with an implanted medical device. An external processor transmits to the implanted medical device an implant data signal having a sequence of HI and LOW logic states at a fixed data bit rate. The pulse width durations of the HI and LOW logic states is adjustable in response to feedback telemetry data from the implantable medical device.

Abstract: An external device for a hearing implant system and a hearing implant system having an external device is described. An external transmitter generates a radio-frequency inductive link signal to an implanted receiver including a sequence of data word segments which communicate data to the implanted receiver, and a sequence of data word pause segments between each data word segment which communicate energy without data to the implanted receiver. A data word pause controller controls the inductive link signal during the data word pause segments according to an energy management rule.

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.
