    • A plurality of phases of sniff operations are performed for detecting wake-up signals being received by an implantable medical device (IMD), including a phase that performs a staged detection of whether the integrated frequency deviation of a received signal is outside of an expected frequency deviation range, where sniff operations are aborted if the integrated frequency deviation of the received signal falls outside of corresponding high and low thresholds in any stage, wherein the difference between the high and low thresholds tightens with each subsequent stage and an average frequency deviation over all completed stages are used in the calculations. One phase of sniff operations includes a dual frequency modulation (FM) detector including a first FM detector that introduces a small delay in a received signal providing an average frequency estimate and a second FM detector having a larger delay that is adjusted based on the estimated average frequency.

    • A low power method and apparatus for detecting wake -up signals in sniff processing performed in an implantable medical device (IMD) using a staged detection of RF energy in signals received in order to conserve current consumption. Incoming signals are monitored in a plurality of detection stages which each incrementally increase the accuracy of detecting whether the received signal is a wake-up communication signal. A desired number of stages of signal quantity measurements are performed such that a combined signal quantity is calculated by updating the signal quantity measurements performed in prior stages with signal quantity measurements performed at each stage. The combined signal quantity of the received communication signal is compared at each detection stage against a corresponding threshold value for that stage. The staged detection process aborts sniff processing if the combined signal quantity fails to meet the corresponding threshold value for that stage.
    • 一种低功率方法和装置,用于检测在可植入医疗装置(IMD)中进行的嗅探处理中的唤醒信号,该方法使用接收的信号中的RF能量的分阶段检测来节省电流消耗。 在多个检测级中监视输入信号,每个检测级逐步增加检测接收信号是否为唤醒通信信号的准确度。 执行信号量测量的期望数量的级,使得通过在每个阶段执行信号量测量来更新在先前阶段执行的信号量测量来计算组合信号量。 将接收到的通信信号的组合信号量在每个检测阶段与该阶段的相应阈值进行比较。 如果组合信号数量不能满足该阶段的相应阈值,则分段检测过程中止嗅探处理。
