    • An apparatus comprises a therapy circuit that provides a neural stimulation current, an impedance measurement circuit that measures a value of impedance at the output of the therapy circuit, a supply voltage generating circuit that provides an adjustable supply voltage value to the therapy circuit including a first supply voltage value when in a first mode, and a control circuit communicatively coupled to the therapy circuit, the impedance measuring circuit, and the supply voltage generating circuit. The control circuit, upon receiving an indication to exit the first mode, initiates an impedance measurement by the impedance measurement circuit, determines the second supply voltage value using the impedance measurement, and initiates a change from the first supply voltage value to the second supply voltage value. The second supply voltage value is sufficient to operate the therapy circuit and to provide a specified load current value to the measured impedance.
    • 一种装置,包括提供神经刺激电流的治疗电路,测量治疗电路输出端的阻抗值的阻抗测量电路,向治疗电路提供可调电源电压值的电源电压产生电路,该电源电压值包括第一 在第一模式下提供电压值,以及通信地耦合到治疗电路,阻抗测量电路和电源电压产生电路的控制电路。 控制电路在接收到退出第一模式的指示时,通过阻抗测量电路启动阻抗测量,使用阻抗测量确定第二电源电压值,并且启动从第一电源电压值到第二电源电压的改变 值。 第二电源电压值足以操作治疗电路并为测量的阻抗提供规定的负载电流值。

    • A method of conserving power and extending the life of a battery in an implantable rate-responsive cardiac rhythm management device. In accordance with the preferred embodiment, a first physiologic sensor is used to enable a power consuming feature only when the first sensor produces an output falling within a predetermined range and subsequently disables the power consuming feature when the output of the first sensor falls back outside the predetermined range. The first sensor may measure heart rate, physical movement, posture or other parameters and the power consuming feature may comprise further physiologic sensors, a different mode of pacing or a combination thereof.
    • 一种在植入式速率响应心律管理装置中节省电力并延长电池寿命的方法。 根据优选实施例,第一生理传感器被用于仅当第一传感器产生落在预定范围内的输出时才能够实现功率消耗特征,并且随后当第一传感器的输出落到外部时,禁用功耗特征 预定范围。 第一传感器可以测量心率,身体运动,姿势或其他参数,并且功耗特征可以包括进一步的生理传感器,不同的起搏模式或其组合。
