Low power signal transmission
First Claim
1. A method of low-power communication for a hearing system that includes a hearing implant associated with a first ear of a user, the hearing system further including an external signal processor, the method comprising:
- transmitting pulses by one of the hearing implant and the external signal processor;
receiving the pulses at an input to a time-gated amplifier of the other one of the hearing implant and the external signal processor, the amplifier for amplifying the pulses received at the input; and
synchronizing turning on of the time-gated amplifier with the possible receipt of transmitted pulses based, at least in part, on a transmitted pulse received at the input.

Abstract
A low-power implant system. The system includes an implant for implantation into a person, such as a cochlear implant or a middle ear implant. The implant is capable of communicating with a device via transmission of ultra wideband pulses. The device may be adapted to be worn external to the person, or may be a second implant. So as to conserve battery power, the transmitted ultra wideband pulses may have a low duty cycle of approximately 1/1000 or less. Power savings may also be realized by using time-gating amplifiers in the implant and/or device receiver.
