1. A low-power implant system comprising:
- an implant for implantation into a person, the implant capable of communicating via transmission of ultra wideband pulses; and
a device capable of wirelessly communicating with the implant via ultra wideband pulse transmission, wherein the device includes a transmitter capable of transmitting ultra wideband pulses, wherein the implant includes a receiver capable of receiving ultra wideband pulses, and wherein the receiver includes;
a time-gated amplifier having an input, the amplifier for amplifying the pulses received at the input; and
a controller that synchronizes turning on of the time-gated amplifier with the possible receipt of pulses transmitted by the transmitter based, at least in part, on a 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.
