A capsule endoscopic system comprising: a capsule endoscope, wherein the capsule endoscope comprises, a capsule housing (110, 210, 310, 410, 510, 610); and first circuits (115, 630) inside the capsule housing; a docking station to interface with the capsule endoscope, wherein the docking station comprises a docking bay to receive the capsule endoscope; second circuits; and contact means to cause the first circuits to connect to the second circuits when the capsule endoscope is docked in the docking bay in first rotational orientation and second rotational orientation, wherein the contact means comprises, one or more first contacts (117a/b/c, 217a/b/c, 317a/b/c, 417a/b/c, 517a/b/c) disposed fixedly on or through the capsule housing while maintaining the capsule housing water-tight, wherein said one or more first contacts are connected to the first circuits, and wherein said one or more first contacts comprise one or more feedthrough connectors (117a/b/c, 217a/b/c, 317a/b/c), and said one or more feedthrough connectors (117a/b/c) comprise studs; and one or more second contacts (122/123, 322, 422a/b/c, 522a/b/c) in the docking stations, wherein said one or more second contacts are coupled to the second circuits; and wherein said one or more second contacts are configured to contact said one or more first contacts and to cause the first circuits to connect to the second circuits when the capsule endoscope is docked in the first rotational orientation and the second rotational orientation, wherein said one or more second contacts (122/123) comprise one or more annular connectors, configured to be symmetric around a longitudinal axis through a center of the capsule endoscope and characterised in that said one or more annular connectors (122/123) comprise a series of spokes extended radially inward from an annular outer ring. a capsule endoscope, wherein the capsule endoscope comprises, a capsule housing (110, 210, 310, 410, 510, 610); and first circuits (115, 630) inside the capsule housing; a capsule housing (110, 210, 310, 410, 510, 610); and first circuits (115, 630) inside the capsule housing; a docking station to interface with the capsule endoscope, wherein the docking station comprises a docking bay to receive the capsule endoscope; second circuits; and contact means to cause the first circuits to connect to the second circuits when the capsule endoscope is docked in the docking bay in first rotational orientation and second rotational orientation, wherein the contact means comprises, one or more first contacts (117a/b/c, 217a/b/c, 317a/b/c, 417a/b/c, 517a/b/c) disposed fixedly on or through the capsule housing while maintaining the capsule housing water-tight, wherein said one or more first contacts are connected to the first circuits, and wherein said one or more first contacts comprise one or more feedthrough connectors (117a/b/c, 217a/b/c, 317a/b/c), and said one or more feedthrough connectors (117a/b/c) comprise studs; and one or more second contacts (122/123, 322, 422a/b/c, 522a/b/c) in the docking stations, wherein said one or more second contacts are coupled to the second circuits; and wherein said one or more second contacts are configured to contact said one or more first contacts and to cause the first circuits to connect to the second circuits when the capsule endoscope is docked in the first rotational orientation and the second rotational orientation, wherein said one or more second contacts (122/123) comprise one or more annular connectors, configured to be symmetric around a longitudinal axis through a center of the capsule endoscope and characterised in that said one or more annular connectors (122/123) comprise a series of spokes extended radially inward from an annular outer ring. one or more first contacts (117a/b/c, 217a/b/c, 317a/b/c, 417a/b/c, 517a/b/c) disposed fixedly on or through the capsule housing while maintaining the capsule housing water-tight, wherein said one or more first contacts are connected to the first circuits, and wherein said one or more first contacts comprise one or more feedthrough connectors (117a/b/c, 217a/b/c, 317a/b/c), and said one or more feedthrough connectors (117a/b/c) comprise studs; and one or more second contacts (122/123, 322, 422a/b/c, 522a/b/c) in the docking stations, wherein said one or more second contacts are coupled to the second circuits; and wherein said one or more second contacts are configured to contact said one or more first contacts and to cause the first circuits to connect to the second circuits when the capsule endoscope is docked in the first rotational orientation and the second rotational orientation, wherein said one or more second contacts (122/123) comprise one or more annular connectors, configured to be symmetric around a longitudinal axis through a center of the capsule endoscope and characterised in that said one or more annular connectors (122/123) comprise a series of spokes extended radially inward from an annular outer ring.
