Abstract: A user interface for a power transfer device configured to wirelessly transfer transcutaneous power to an implantable medical device. The user interface may enable a user to start and stop power transfer, e.g., to recharge a battery? on the implantable medical device. In some examples, the user interface may present the user a display that indicates whether the power transfer device is performing open or closed loop recharging, indicate and control therapy delivery? status of the implantable medical device and indicate both die power transfer device battery? level and/or indicate the battery level for the implantable medical device, lire user interface may communicate with the user with a set of indicator lights that may flash, pulse and change color as needed.

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: Devices and methods described herein facilitate rapid wireless recharging, while reducing risk of injury, damage, or discomfort caused by heat generated during recharging. The embodiments described herein are useful in a variety of context, including for IoT devices, personal electronics, electric vehicles, and medical devices, among others. Such devices can prevent localized overheating of the device.

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.

Abstract: Techniques to provide haptic feedback to a patient to help the patient align a medical device to a location on their anatomy. In some examples, the patient may align a recharging device to a medical device that is implanted at the location on their anatomy. In some examples, the electrical stimulation can be delivered in such a way that the patient may or may not be able to feel the electrical stimulation, e.g., experience a paresthesia sensation. The system of this disclosure may intentionally adjust the stimulation intensity to provide patient feedback for alignment, such as alignment of the recharging device with the implanted device. Alignment of the recharging device with the implanted device may improve energy transfer, which may, for example, recharge the implanted device more efficiently.

Abstract: Techniques for estimating the temperature of an external portion of a medical device are described. In an example, processing circuitry may determine a temperature sensed by at least one temperature sensor of an internal portion of the device, and determine, based on an algorithm that incorporates the temperature of the internal portion of the device, an estimated temperature of a second portion of the device, wherein the algorithm is representative of an estimated temperature difference between the first portion of the device and the second portion of the device based at least in part on a dynamic transfer function that operates in a time-domain.
