    摘要： System and methods for adjusting electrical therapy based on impedance changes are disclosed herein. A method in accordance with a particular embodiment includes applying a therapeutic electrical signal to a patient via an implanted portion of a patient stimulation system that includes a signal delivery device in electrical communication with a target neural population of the patient. The electrical signal is delivered in accordance with a signal delivery parameter having a first value. Using the implanted portion of the patient stimulation system, a change in an impedance of an electrical circuit that includes the signal delivery device is detected. Based at least in part on the detected impedance change, the method can further include automatically adjusting the value of the signal delivery parameter from the first value to a second value different from the first, without human intervention.

    摘要： A microcontroller power management system wherein the voltage of a power supply is monitored and the microcontroller central processing unit ("CPU") receives an interrupt signal when the supply voltage falls below a predetermined level. The CPU monitors the duration of the low voltage condition and switches into a sleep mode, after storing any data in its registers that are not maintained in the sleep mode, when that duration exceeds a fixed limit that indicates more than a temporary power glitch is being experienced. If only a short power glitch, the CPU continues normal operation. A large capacitor connected to the power supply input to the microcontroller provides enough energy for the microcontroller to operate normally during short glitches and to operate in a sleep mode for a considerable time, thereby maintaining data in CMOS static RAM until power is restored. This is particularly useful for battery operated systems, responding to both a low battery voltage condition and to a complete loss of power during battery replacement.

    摘要翻译： 一种微处理器电源管理系统，其中监视电源的电压，并且当电源电压低于预定电平时，微控制器中央处理单元（“CPU”）接收中断信号。 在将任何数据存储在不保持在睡眠模式的寄存器中时，CPU将监视低电压状态的持续时间并切换到休眠模式，当该持续时间超过指示超过临时电源故障的固定限制时 有经验的。 如果只有短暂的电源故障，CPU会继续正常运行。 连接到微控制器的电源输入的大电容器提供足够的能量，以使微控制器在短时间毛刺期间正常工作并在睡眠模式下工作相当长的时间，从而在电源恢复之前保持CMOS静态RAM中的数据。 这对于电池供电的系统特别有用，对电池电压低的条件和电池更换期间电源的完全损失做出回应。
