Disclosed herein is an electronic device. The electronic device includes a housing provided to accommodate a printed circuit board, a cover coupled to the housing, and including a coupling protrusion protruding to a side of the housing to be accommodated in the housing, and including a coupling hole formed in the coupling protrusion, a fastening pin arranged in the coupling hole and configured to couple to the housing, and a sealing member arranged between an inner wall forming the coupling hole and the fastening pin to seal the coupling hole. Various other embodiments are possible.

A waterproof structure includes a shell which is provided with an air hole extending therethrough, a waterproof membrane is provided in a mounting cavity in the shell which abuts the inner side opening of the air hole, and the air hole is internally provided with a ball having waterproof performance and a constraint structure which constrains the ball in a preset range in the air hole; the preset range has a space allowing the ball to freely move; in a gas environment, there is gap between the ball and a boundary face of the present range, so as to allow the communication between the inner side opening and the outer side opening of the air hole; and the ball can press against the constraint structure under the pushing of liquid entering from the outer side opening and seal the inner side opening.

A pump assembly includes an electric motor with a printed circuit board with a controller, a pump driven by the electric motor, a housing surrounding the printed circuit board, and a connector which is fastened on an outside of the housing by a flange, which covers an opening of the housing, and which includes contacts directly electrically contacting the printed circuit board. The contacts pass through the opening of the housing. The connector includes a main housing in which the contacts extend and which adjoins the flange. The connector includes a pressure compensator which is in the main housing.

An enclosure for electronics comprises a shell. The shell defines an exterior of the enclosure and accommodated a main chamber inside the shell. The enclosure comprises a partition defining a relief chamber extending inwardly of the shell. The partition has a relief aperture communicating between the relief chamber and the main chamber. The partition has a gas-permeable barrier membrane arranged to cover the aperture. The shell has an opening communicating between the relief chamber and the exterior of the enclosure. The enclosure is suitable for vehicle-mounted radar sensor electronics. The enclosure may provide IP6K6K environmental sealing.

A waterproof membrane of the present disclosure has an insertion loss of 5.0 dB or less for sound with a frequency of 1 kHz, and an insertion loss of 5.0 dB or less for sound with a frequency of 10 kHz when a permeation region for sound of the waterproof membrane has an area of 1.3 mm.sup.2. The waterproof membrane of the present disclosure can cope with further size reduction of the permeation region. A waterproof member of the present disclosure includes the above-mentioned waterproof membrane of the present invention and a support member joined to the waterproof membrane.

A housing for a control device, including: a cover; a base plate; an elastic adhesive connection; in which the elastic adhesive connection provides a wet seal between the cover and the base plate. Also described are a related brake control device and a commercial vehicle.

A method for estimating the remaining useful life of a pressure compensator of a subsea arrangement, the method including determining displacement data related to displacements of the pressure compensator during a time period; and estimating the remaining useful life of the pressure compensator in relation to a failure mode of the pressure compensator based on the determined displacement data of the pressure compensator. A system including a subsea arrangement and a control system, a computer program product, and a computer program, are also provided.

A waterproof membrane of the present disclosure has an insertion loss of 5.0 dB or less for sound with a frequency of 1 kHz, and an insertion loss of 5.0 dB or less for sound with a frequency of 10 kHz when a permeation region for sound of the waterproof membrane has an area of 1.3 mm.sup.2. The waterproof membrane of the present disclosure can cope with further size reduction of the permeation region. A waterproof member of the present disclosure includes the above-mentioned waterproof membrane of the present invention and a support member joined to the waterproof membrane.

The present invention provides a connector with waterproof structure and the manufacturing method, comprising: an base, providing the support of components in the connector; housing, enclose the components inside of the connector; the connecting groove, located on the base with slot shape; the connecting unit, mounted on the connecting groove and penetrated out with the base; the first retaining block, disposed between the connecting groove and the outer wall of the housing, separating the upper end of the base into a plurality of waterproof compartments, wherein the waterproof compartment is filled with waterproof glue; and the upper lid, upper lid, sealing the upper end of the base to achieve the purpose of preventing moisture and dust particles from entering the connector.

A subsea enclosure arrangement for a subsea component, the enclosure includes walls of a fluid tight material, each wall terminating in a flange; a cover for closing the enclosure; an elastomeric seal between the flange and the cover; compressive members to apply a compressive force to the elastomeric seal, via the cover and the flange; a bracket connecting the flange to the cover; a weld seal between the bracket and the flange; and a weld seal between the bracket and the cover.
