    • An in-vivo device may allocate a sensing window in a work cycle for sensing and processing localization signals to determine the location/orientation of the in-vivo device. The in-vivo device may use a timing unit to schedule transmission of data frames and the sensing of the localization signals relative to a reference time embedded in work cycles. The timing unit may produce a clock signal based on which the in-vivo device may measure time specifics, which define the sensing window, relative to the reference time. A receiver may use data embedded in data frames to restore the clock signal and the reference time, and, from them, and using identical or similar time specifics, generate a synchronization signal for a localization signals source (LSS) to enable the LSS to generate localization signals in synchronization with the sensing windows.
    • 体内装置可以在工作循环中分配感测窗口,用于感测和处理定位信号以确定体内装置的位置/取向。 体内装置可以使用定时单元调度数据帧的传输和相对于嵌入在工作周期中的参考时间的定位信号的感测。 定时单元可以产生时钟信号,基于该时钟信号,体内装置可以相对于参考时间来测量限定感测窗口的时间细节。 接收机可以使用嵌入在数据帧中的数据来恢复时钟信号和参考时间,并且从它们使用相同或类似的时间细节来产生用于定位信号源(LSS)的同步信号,以使得LSS能够产生 定位信号与感应窗口同步。
