A personal communication device (PCD) holder including (i) a first housing portion including a material that causes the first housing portion to be data signal blocking; (ii) a second housing portion including a material that causes the second housing portion to be data signal blocking; and (iii) a data signal blocking gasket fitted to at least one of the first and second housing portions, the gasket positioned and arranged such that when the first and second housing portions are mated together to form an enclosure about the PCD, the data signal blocking gasket engages and seals to the other of the first and second housing portions to ensure that the enclosure is completely data signal blocking regardless of whether imperfections are present in an interface between the mated first and second portions.

An electromagnetic wave absorber includes: a first layer having a first enclosing layer that encloses an electromagnetic wave radiator, and a first metal film formed on the first enclosing layer.

A method for shielding a compartment in a module of an electronic device includes molding the module using a mold material that activates when a laser is applied. The method also includes cutting a trench on the mold of the module around a certain portion of the module using the laser. The method further includes plating the trench using a certain metal. The method also includes filling the trench with a filler material. The method further includes encapsulating the module, the mold, the trench, and the filler material.

A method for electro-magnetic interference shielding (EMI) of a battery box (10) or other EMI emitting device in a vehicle. The method includes the steps of forming a battery box enclosure (10) with an effective amount of a shielding material (20) attached to the enclosure (10). In one embodiment the box (10) is an SMC or injection molded preformed enclosure (10), and a metallic material (20) is attached to the enclosure (10) on an interior or exterior side of the enclosure (10). In another embodiment the enclosure (10) and mesh (20) are formed in the same mold cavity (24) for embedding the shielding material (20) in the enclosure (10).

A front on an extension line of a built-in front camera lens part of said portable electronic device during use of the cradle is shielded by an opaque or translucent lens shielding member provided on the front face side of the cradle 3 for portable electronic devices of the present invention, thereby disabling photography of front surrounding conditions of the cradle, even if an operation of front camera unwanted by an owner is performed, and a microphone hole of the electronic device 11 is shielded by providing a microphone hole shielding member 13 in a space between the charging stand 4 and a housing of the electronic device 11 mounted thereon, and therefore it becomes possible to reduce a risk of an outflow of ambient voice information of the cradle, even if an operation of microphone unwanted by an owner is performed.

A power converter includes a semiconductor modules, a capacitor, a housing, a shield layer and a collar member. The capacitor is electrically connected to the semiconductor modules. The housing houses at least the semiconductor modules and the capacitor. The shield layer is electrically conductive and provided on and covers at least one of inner and outer surfaces of the housing. The collar member is electrically conductive and integrated with the housing. The collar member is configured to allow a fastener to be inserted through the collar member such that the housing is fixed to a vehicle-side member via the fastener. The collar member is electrically conductively joined to the shield layer.

Provided is a housing that effectively serves to block high-frequency electromagnetic waves in addition to low-frequency electromagnetic waves. A housing that houses an electronic or electric device includes at least one of a copper layer serving as a diamagnetic layer and a nickel layer serving as a ferromagnetic layer, stacked on each of front and back sides of an iron base member, and a bright tin layer further stacked thereon as an outermost layer.
