AC/DC multi-axis accelerometer for determining patient activity and body position
摘要：
An implantable cardiac stimulation device which determines stimulation based upon the patient's body position and activity level while eliminating special implantation or calibration procedures. To eliminate such special implantation and calibration procedures, the stimulation device correlates the patient's body position using a multi-axis DC accelerometer or other sensor during times of high activity and determines a patient's standing position value. During other times, the stimulation device compares the signals from the accelerometer to the standing position value to determine the patient's current body position. Based upon the current body position and the activity level, the stimulation device determines the necessary stimulation to deliver to the patient.
摘要（中）：

一种可植入心脏刺激装置，其基于患者的身体位置和活动水平确定刺激，同时消​​除特殊植入或校准过程。 为了消除这种特殊的植入和校准过程，刺激装置在高活动时间期间使用多轴DC加速度计或其他传感器来关联患者的身体位置并且确定患者的站立位置值。 在其他时间，刺激装置将来自加速度计的信号与站立位置值进行比较，以确定患者的当前身体位置。 基于当前身体位置和活动水平，刺激装置确定必要的刺激以递送给患者。
