To eliminate galvanic corrosion, a housing includes a clad material. The clad material includes an interior metal disposed within an exterior metal. The exterior metal is different from the interior metal. The housing further includes a clad interface and a melt interface. The melt interface includes a layer of hardened flux disposed on a portion of the interior metal.

An in-vehicle electrical component circuit unit : includes an electrically insulative holding body configured to hold a circuit member ;a plate wall portion configured to cover a casing through hole provided in an in-vehicle electrical component ; a connector including a connection member that is held by the plate wall portion ; and a sealing member (126) that is provided on a first surface , which is a surface of the plate wall portion that is to be attached to the casing (132), and is configured to come into contact with a peripheral edge of the casing through hole , wherein a portion of the connection member that protrudes on a first surface side includes a circuit-side connection portion (120), the circuit-side connection portion is detachably connectable to the circuit member , and the circuit-side connection portion is inserted into the casing through hole from outside the casing and connected to the circuit member

A container for communication devices and communication systems used in cellular networks. There is a need for resilient systems that can withstand extreme weather events. Cellular network infrastructure located close to coastal regions is particularly prone to disruptive failures. A container for an electronic communications device is also provided including: a housing that surrounds at least one mounting plate on which electrical devices and electronic devices are supported. The housing is received around a top edge by a recess in a top plate and around a bottom edge by a recess in a bottom plate. The top and bottom plates are clamped to seal the housing. In some embodiments the housing is connected to a sea borne infrastructure such as buoy. Node frames enable a communications infrastructure that has no single point of failure.

An electronic device can include a housing component that can define an interior surface and an exterior surface of the device, a metallic film deposited on the interior surface and extending at least partially onto the exterior surface, and a ceramic film deposited on the exterior surface and at least partially over a portion of the metallic film on the exterior surface. The ceramic film can be in electrical communication with a portion of the metallic film deposited on the interior surface to form an electrical pathway from the exterior surface to the interior surface.

Various embodiments of a sealed package and a method of forming such package are disclosed. The package includes a housing having an inner surface and an outer surface, a dielectric substrate having a first major surface and a second major surface, and a dielectric bonding ring disposed between the first major surface of the dielectric substrate and the housing, where the dielectric bonding ring is hermetically sealed to both the first major surface of the dielectric substrate and the housing. The package further includes an electronic device disposed on the first major surface of the dielectric substrate, and a power source disposed at least partially within the housing and electrically connected to the electronic device.

A submersible control system with a control panel. The control panel has a frame to house electronic components. The frame has a connection opening for wiring required for an electrical connection to the electrical components. An outer door is attached to the frame to be water-tight to the frame in a closed position thereof. A conduit is sealed to be water-tight with respect to the connection opening. The conduit is filled with an epoxy for water-tight sealing an interior of the conduit to the wiring fed through the conduit. The control panel will remain water-tight for at least 24 hours after being submerged.

An in-vehicle device includes a housing having an opening, an openable and closable cover disposed over the opening, a sealing member disposed around the opening such that the sealing member is held between the housing and the cover when the cover is closed, at least one first vibration sensor to measure mechanical vibration of the cover, and a degradation determiner to determine whether any degradation occurs in the sealing member. The degradation determiner determines whether any degradation occurs in the sealing member on the basis of the mechanical vibration measured by the at least one first vibration sensor while the cover is closed.

An electronic control device includes: a first board on which a bus bridge and an external communication connector are mounted; a second board on which an accelerator SoC is mounted, the second board being electrically connected to the first board; and a B-to-B connector capable of performing signal transmission between the bus bridge and the accelerator SoC.
