Abstract
A capsule endoscopic system is disclosed, where the system comprises a capsule device and a docking device. The capsule device comprises a battery, a secondary coil, an optical transmitter all enclosed in a capsule housing. The docking device comprises a primary coil to generate an alternating magnetic field, a primary core and optical receiver to receive an optical signal. The alternating magnetic field is coupled to the secondary coil to supply power to the capsule device when the capsule device is at a docked position in the docking device. The primary core is arranged to concentrate the alternating magnetic field on the secondary coil when the capsule device is at the docked position. Furthermore, the capsule endoscopic system is arranged so that an optical path is formed between the optical transmitter and the optical receiver when the capsule device is at the docked position.
