一种用于访问车辆(30)或提供车辆(30)的操作控制的系统,包括发起器设备和嗅探器设备(5902、5906)。发起器设备(5902)包括:极化天线;发送器,经由极化天线从车辆(30)向响应器/便携式访问设备(5904)发送第一音调信号;以及接收器,从响应器设备(5904)接收响应于第一音调信号的第二音调信号。嗅探器设备(5906)包括:第二极化天线;以及第二接收器,经由第二极化天线接收来自发送器的第一音调信号和来自响应器设备(5904)的第二音调信号。嗅探器设备(5906)确定包括相应的相位延迟的第一音调信号和第二音调信号的状态。发起器或嗅探器设备(5802、5906)基于包括相应的相位延迟的状态,估计从车辆(30)到响应器设备(5904)的第一距离或从响应器设备(5904)到嗅探器设备(5906)的第二距离。

    Systems, apparatuses, and methods for implementing efficient power optimization in a computing system are disclosed. A system management unit configured to track computing activity of a computing device while processing each frame of a plurality of frames. The computing activity is tracked at least for a given period of time comprising a plurality of time slices. The system management unit further correlates a time slice associated with a given frame with a time slice associated with at least one previously processed frame from the plurality of frames, based at least in part on the tracked computing activity. The system management unit predicts a clock frequency to render the given frame, based at least in part on the correlation and renders the given frame using the predicted clock frequency.
