A testing system capable of shielding from environment noise uses a foldable electromagnetic shielding box to isolate devices that will produce electromagnetic interference to a test object, so as to reduce the influence of these devices on the measurement of the test object. In an embodiment, measuring equipment and the test object are disposed in the foldable electromagnetic shielding box for being shielded from outside electromagnetic waves. In another embodiment, the measuring equipment is disposed in the foldable electromagnetic shielding box while the test object is disposed outside the foldable electromagnetic shielding box, so that the test object to be test is shielded from electromagnetic waves from the measuring equipment. The foldable electromagnetic shielding box can be folded into a stack for convenience of storage or transport.

An embodiment of the present disclosure provides an electromagnetic shield member that can improve heat dissipation from an electric wire, and a wire harness that includes the electromagnetic shield member. An electromagnetic shield member has rectangular tubular housing portions in which electric wires are individually housed. The housing portions are provided with pressing portions that are formed by cutting and raising portions of the housing portions inward, and that press the electric wires.

A radar apparatus includes a board, a high-frequency integrated circuit mounted to the board, a metallic housing arranged to face the high-frequency integrated circuit, and a radio-absorbing and heat-dissipating unit. The radio-absorbing and heat-dissipating unit includes a radio-absorbing and heat-dissipative gel. The radio-absorbing and heat-dissipating unit is configured to cover at least part of the high-frequency integrated circuit and to be in contact with the metallic case.

A vapor chamber is provided that allows space-saving and weight reduction of a device in which the vapor chamber is to be mounted. The vapor chamber has a container in which a cavity portion is formed by one plate-shaped body and another plate-shaped body facing the one plate-shaped body, and a working fluid enclosed in the cavity portion. The container includes a heat transfer portion that transfers heat by a phase change of the working fluid, and an extending portion that extends outwards from the heat transfer portion and has a function other than a heat transfer function.

A camera module (1) for a motor vehicle, in particular for driver monitoring in the passenger compartment, including at least one printed circuit board (2) and a shield for enclosing the printed circuit board (2). The shield includes at least a first shielding part (7) and a second shielding part (10). The first shielding part (7) is a ring shaped part and the second shielding part (10) is a hat shaped part put over, enclosing, and contacting the first shielding part (7).

A method, system and paint for suppressing emission of high frequency electromagnetic radiation from an electronic system, the electronic system including at least one power supply unit, at least one printed circuit board (PCB) and at least one integrated circuit are provided. The method includes providing an electrically conductive housing configured to accommodate and encase the electronic system, the housing having an inner conductive surface, and applying a layer of an electromagnetic absorbing paint to the inner conductive surface of the housing to substantially cover the inner surface by the layer, the electromagnetic absorbing paint comprises a liquid matrix and an electromagnetic absorbing material.

A housing device for isolating electromagnetic interference emitting devices includes a structural frame for housing the electromagnetic interference emitting devices. The housing device further includes a non-structural electromagnetic interference isolating enclosure. The non-structural electromagnetic interference isolating enclosure is for encapsulating the structural frame. The non-structural electromagnetic interference isolating enclosure includes an access portion that enables the structural frame to be accessed. The access portion includes a vent.
