Abstract: This disclosure describes devices, systems, and techniques for recharging power sources using RF energy received by one or more antennae. In one example, an implantable medical device includes a rechargeable power supply and an antenna configured to receive radio frequency (RF) energy having one or more frequencies within at least one of a first range from 1 MHz to 20 MHz or a second range from 100 MHz to 700 MHz. The implantable medical device may also include charging circuitry configured to convert the RF energy to a direct current (DC) power and charge the rechargeable power supply with the DC power.

Abstract: Disclosed is a system for recharging a selected power source wirelessly, such as through a power transmission. The power source may be positioned within a subject and be charged wirelessly through the subject, such as tissue of the subject. A thermal transfer system is provided to transfer or transport thermal energy from a first position to a second position, such as away from the subject.

Abstract: A wireless power transfer system and devices that are configured to perform techniques to detect a single fault in primary processing circuitry by using second, independent processing circuitry. The techniques may include calculating and verifying an integrated output power dose. Verifying the integrated output power dose may include, for example, secondary processing circuitry calculating the integral of power delivered over a predetermined time duration and compares the calculated integral to an expected integral dose curve stored at a memory location accessible by the secondary processing circuitry. The detection techniques may also include determining a maximum output power profile. The secondary processing circuitry may receive a commanded output power target from the primary processing circuitry and compare the commanded output power to the maximum allowed output power vs. time.
