    Abstract: Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue during a charging session used to recharge the rechargeable power source. In one example, a temperature sensor may sense a temperature of an internal portion of a device, wherein the housing of the device is not directly thermally coupled to the temperature sensor. A temperature for the housing of the device may then be estimated based on the sensed temperature provided by the non-thermally coupled temperature sensor. A processor may then control charging of the rechargeable power source based on the determined temperature for the housing.

    Abstract: Techniques relate to operating a medical device by classifying a detected posture state of a patient. This classification may be performed by comparing the detected posture state of the patient to posture state definitions available within the system. Each definition may be described in terms of a parameter (e.g., vector) indicative of a direction in three-dimensional space. The posture state definitions may be calibrated by automatically estimating values for these parameters, thereby eliminating the need for the patient to assume each posture state during the calibration process to capture actual parameter values. According to another aspect, the estimated parameter values may be updated as the patient assumes various postures during a daily routine. For instance, estimated vectors initially used to calibrate the posture state definitions may be changed over time to more closely represent posture states the patient actually assumes, and to further adapt to changes in a patient's condition.

    Abstract translation: 技术涉及通过对检测到的患者的姿势状态进行分类来操作医疗装置。 可以通过将检测到的患者的姿势状态与系统内可用的姿势状态定义进行比较来执行该分类。 可以根据指示三维空间中的方向的参数（例如，矢量）来描述每个定义。 可以通过自动估计这些参数的值来校准姿势状态定义，从而消除了在校准过程期间患者承担每个姿势状态以捕获实际参数值的需要。 根据另一方面，当患者在日常例行程序中呈现各种姿势时，可以更新所估计的参数值。 例如，最初用于校准姿势状态定义的估计矢量可以随着时间而改变以更加紧密地表示患者实际假定的姿势状态，并进一步适应患者状况的变化。
