A component for the passenger compartment of a motor vehicle includes a rigid supporting body, made of plastic material, an outer upholstery skin, made of plastic material, and a padding body made of foamed plastic material, which is set between the rigid body and the outer upholstery skin. The rigid body and the outer skin have portions formed by a polymeric material with carbon-based nanofillers, which have respective inner surfaces facing the padding body, which include one or more paths where said polymeric material with carbon-based nanofillers has been rendered electrically conductive by laser irradiation to define one or more electrical circuits, and one or more piezoresistive areas where the polymeric material has been rendered piezoresistive by laser irradiation to define one or more electrical switches, which can be activated by exerting a localized pressure on the outer upholstery skin.

A keyboard covering film including a fabric layer, a transparent layer and a mask layer is disclosed. The transparent layer is disposed on an upper surface of the fabric layer. The mask layer is disposed on a lower surface of the fabric layer. The transparent layer and the fabric layer are treated by a hot pressing process to form a number of keycap receiving sections. The keycap receiving sections, the fabric layer and the mask layer are located on the same side of the transparent layer. The fabric layer and the mask layer have hollow patterns within the keycap receiving sections, wherein the hollow patterns are formed by removing a portion of the fabric layer and the mask layer.

A dome switch includes a first release membrane, a dome, a shim, and a second release membrane, the dome is mounted at an underside of the first release membrane, the second release membrane seals one end of a through opening of the shim, when the dome switch is mounted on a circuit board, a sealed space can be formed, ensuring that in the manufacture process of a smart card, the glue will not flow into the dome and hence the second release membrane will not be connected and adhered to the glue within the card, which may otherwise result in poor hand-tactile impression of the switch. The dome switch and the smart card with the dome switch presents good hand-tactile impression; the production rate is high and the rejection rate and the production cost are low.

A component for the passenger compartment of a motor vehicle includes a rigid supporting body, made of plastic material, an outer upholstery skin, made of plastic material, and a padding body made of foamed plastic material, which is set between the rigid body and the outer upholstery skin. The rigid body and the outer skin have portions formed by a polymeric material with carbon-based nanofillers, which have respective inner surfaces facing the padding body, which include one or more paths where said polymeric material with carbon-based nanofillers has been rendered electrically conductive by laser irradiation to define one or more electrical circuits, and one or more piezoresistive areas where the polymeric material has been rendered piezoresistive by laser irradiation to define one or more electrical switches, which can be activated by exerting a localized pressure on the outer upholstery skin.

A backlight module assembling method is provided for assembling a backlight module of a luminous keyboard. The backlight module includes a first coupled element and a second coupled element in a stack form. Firstly, a positioning device is provided. After the first coupled element is aligned with a predetermined position of an assembling table surface through the positioning device, the first coupled element is placed on the predetermined position. Then, the first coupled element on the predetermined position is adsorbed according to vacuum adsorption. Consequently, the first coupled element is evenly fixed on the predetermined position. After the first coupled element is evenly fixed on the predetermined position, the second coupled element is aligned with and placed on the first coupled element. Consequently, the second coupled element and the first coupled element are combined together.

A dike as an epoxy squeeze out barrier in a fuse device is provided. The fuse device can include first and second layers of laminate material, a cavity formed by central openings of the first and second layers of the laminate material, a fuse element that is supported by at least one of the first and second layers of the laminate material and traverses the cavity, an adhesive located on at least one of the first and second layers of the laminate material for bonding thereof, and a dike located on at least one of the first and second layers of the laminate material and surrounding a circumference of the cavity. When the first and second layers of the laminate material, the fuse element, the adhesive, and the dike are pressed together during manufacture, the dike can prevent the adhesive from flowing into the cavity.
