OPTICAL WIRELESS DOCKING SYSTEM FOR CAPSULE CAMERA

摘要

A capsule endoscopic system with wireless docking device is disclosed, where the system comprises a capsule device and a docking device for receiving the data from the capsule device. The docking device supplies power to the capsule device and retrieves data from the capsule device wirelessly. The capsule device comprises an archival memory to store data captured inside a body lumen by the capsule device, a wireless transmitter to transmit the stored data, a secondary coil. The docking device comprises a primary coil to generate an alternating magnetic field, wherein the magnetic field is coupled to the secondary coil to supply power to the capsule device wirelessly when the capsule device is docked in the docking device and a wireless receiver to receive the data from the capsule device. The wireless link can be a radio frequency (RF) link or an optical link.
