    摘要： 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, and a capsule housing to enclose the battery and the secondary coil in a sealed environment, where the capsule device consists of a first end and a second end in a longitudinal direction of the capsule device, and the battery is located in proximity to the first end and the secondary coil is located in proximity to the second end. The docking device comprises an opening on the docking device, a primary coil to generate an alternating magnetic field, and a primary core. The capsule endoscopic system is arranged so that at least a portion of the secondary coil is enclosed by the primary coil and the battery is outside the primary coil when the capsule device is at the docked position.

    摘要： A capsule endoscopic system is disclosed for receiving data from a capsule device and providing inductive power to the capsule device wirelessly, where the capsule endoscopic system incorporates a feature to automatically protect the capsule device and the docking device from damage if the capsule device is docked in a backward orientation. In one embodiment, the docking device comprises a current sense circuit to detect the current flowing through the primary coil or primary drive circuit. The occurrence of wrong orientation can be detected from the current. A detection/control circuit can be used to provide the needed control in order to prevent damage to the system. In another embodiment, a resonant circuit comprising a capacitor and the primary coil is used to provide the needed protection when the capsule device is docked with a wrong orientation.

    摘要： 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.
