Classification: CPC A  H  Y | IPC A  H

Claim 0:
1. An implantable device, comprising:
a plurality of electrodes;
a power source;
detection circuitry electrically coupled to the electrodes, the detection circuitry configured to detect voltage induced by an electromagnetic field at an interface between tissue of a patient and the electrodes of the implantable device;
communication circuitry configured for wireless communication according to a communication protocol; and
processing circuitry electrically coupled to the detection circuitry, the power source, and the communication circuitry, wherein the processing circuitry is configured to:
broadcast, via the communication circuitry, a first set of advertisements at a first advertising rate according to the communication protocol;
determine that the detection circuitry detected voltage induced by the electromagnetic field;
determine the detected voltage satisfies one or more criteria, the one or more criteria comprising the voltage including one or more predetermined frequencies, the voltage modulating between a plurality of predetermined frequencies at a predetermined rate, or the voltage modulating between a plurality of predetermined frequencies at least a predetermined number of times; and
in response to determining the detected voltage satisfies the one or more criteria, broadcast, powered by the power source and via the communication circuitry, a second set of advertisements at a second advertising rate according to the communication protocol, wherein the second advertising rate is greater than the first advertising rate.
