Self resonant transmitting device
First Claim
1. A device for transmitting power from a location external to a body of a subject to an implant unit internal to the body of the subject, the device comprising:
- an external circuit including an antenna and a self-resonant transmitter circuit adjustable to change a resonant frequency; and
a processor configured tocause delivery of an impulse of energy to the external circuit to excite the external circuit and generate a signal at a frequency within the external circuit to be transmitted to the implant unit by the antenna, andadjust the self-resonant transmitter circuit to provide a match between the resonant frequency of the self-resonant transmitter circuit included in the external circuit and the frequency of the signal generated within the external circuit.

Abstract
A device for powering an implant within a body of a subject from a location external to the subject, wherein the implant requires a threshold rate of power increase in order to operate in at least one mode, may include an antenna configured to wirelessly transmit energy to the implant. The device may also include a power storage unit configured to store energy from a power source incapable of delivering the threshold rate of power increase to enable the implant unit to operate in the at least one mode and a power release unit configured to release a pulse of energy from the power storage unit to the antenna after the power storage unit collects an amount of energy sufficient to enable the implant unit to operate in the at least one mode.
