A data storage system including a docking station, and a dockable external data storage device operates in an underwater environment. The dockable external data storage device includes a housing, a memory disposed within the housing to store data, and a connector assembly mounted on the housing. The connector assembly includes at least one optical transmitter configured to transfer data from the memory to a corresponding optical receiver in the docking station. The connector assembly also includes a self-passivating electrical contact configured to transfer electrical power to the dockable external data storage device from a corresponding power contact in the docking station.

A device that is capable of creating multiple connections on a grounding point in a single airport hangar, as well as reducing the likelihood of there being a tripping hazard over the connected cables, while also assisting in preventing damage to cable connections which may result from vehicles being driven inside an airport hangar.

An object to provide a submarine optical transmission apparatus capable of efficiently housing optical components and electric components. First component housing units can house either or both of an optical component and an electric component and are stacked in a Z-direction. A case can house the first component housing units and a longitudinal direction thereof is an X-direction. A heat dissipating member is disposed in the case and conducts heat generated in the first component housing units to the case.

A switchable subsea connector includes a first connector part, a second connector part removably connected to the first connector part; and a switching unit. The connector parts each include at least one electrical conductor and each switching unit includes at least one individual switching device. Each electrical conductor in at least one connector part is allocated to an individual switching device of the switching unit; wherein each of the individual switching devices includes a micro-electro-mechanical systems (MEMS) switch.

A charging stand is power supply equipment being storable under a ground, and includes: an electrical component for supplying electric power to a vehicle on the ground (e.g., a control device, a power supply circuit, an actuator, a connector, a touch panel display, a communication device, a notification device, and a cable reel device); and a buoyancy generation portion causing a specific component that is at least a part of the electrical component and for which submersion is avoided (e.g., the control device, the power supply circuit, the actuator, the connector, the touch panel display, the communication device, the notification device, and the cable reel device) to float above the ground by buoyancy when water is accumulated in a recess. With the above, when water is accumulated in the recess, the specific component for which submersion is avoided among the electrical component can be floated above the ground by buoyancy.

A cable clip device, including outer cylindrical column, first inner cylindrical column relatively fixed to outer cylindrical column, second inner cylindrical column provided with a sliding groove, spring and cover; the second inner cylindrical column vertically and telescopically slides with respect to the first inner cylindrical column; the first and second inner cylindrical columns are connected with a pull rod; a hook portion on a top of the pull rod can slide in the sliding groove which has first and second positioning points and includes unidirectional first and second tracks connecting the first and the second positioning points; a middle of the cover is provided with a cable clip for clamping cable; a plug connector can pass through the first and second inner cylindrical columns; an outer periphery of the cover is provided with a sealing ring; the cover is detachably arranged above the second inner cylindrical column.
