Abstract
In an implanted medical device system, an external power transmitter and methods for adjusting a rate of search pulse transmission by an external power transmitter of an implanted medical device system are disclosed. According to one aspect, a method includes detecting a condition of the external power transmitter, and selecting among rates of transmission of search pulses based on the detected condition.
Claims20
A method implemented in an external power transmitter of an implanted medical device system, the method comprising:
- detecting satisfaction of at least one condition from a plurality of conditions of the external power transmitter, wherein the plurality of conditions includes a last handling condition that is satisfied when a time of a last handling of the external power transmitter exceeds a last handling threshold;
- selecting among rates of transmission of search pulses based on the satisfaction of the at least one condition, wherein selecting comprises changing a rate of transmission of the search pulses from a first rate to a second rate;
- and
- initiating power transmission in response to receipt of the search pulses by an internal controller of the implanted medical device system.
An external power transmitter of an implanted medical device system, the external power transmitter comprising processing circuitry configured to:
- detect satisfaction of at least one condition from a plurality of conditions of the external power transmitter, wherein the plurality of conditions includes a last handling condition that is satisfied when a time of a last handling of the external power transmitter exceeds a last handling threshold;
- select among rates of transmission of search pulses based on the satisfaction of the at least one condition, wherein the processing circuitry is configured to select by changing a rate of transmission of the search pulses from a first rate to a second rate;
- and
- initiate power transmission in response to receipt of the search pulses by an internal controller of the implanted medical device system.
