Abstract

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.

Description

technical field [0001] The present invention relates generally to in vivo systems, and more particularly to a synchronization method for synchronization between an in vivo device and an in vivo device positioning system, and an in vivo system and a positioning signal system using the synchronization method. Background technique [0002] In vivo measurement systems are known in the art. Some in vivo devices / systems spanning the gastrointestinal (GI) system may include one or more imaging sensors and / or other types of sensors for imaging (eg, capturing images of) the interior of the GI system. In vivo devices may pass through the GI system by peristaltic forces applied by the digestive system or by maneuvering through the GI system (eg, magnetically). Some applications require knowledge of the current position and / or current orientation of the in-vivo device involved. For example, in order to magnetically manipulate an in-vivo device, such as a GI system, the magnetic steeri...
