Abstract: Corrosion-resistant electromagnetic interference (“EMI”) shielding material. The material is provided as an admixture of an elastomeric polymeric component and a filler component. The filler component is provided as glass or aluminum particles which are electrolessly-plated with a plating of a nickel-phosphorous alloy.

Abstract: An assembly for mounting electronic components includes a face plate comprising a thermoplastic material. The face plate includes a retaining element for securing a captive screw and spring assembly for mounting an electronic printed circuit board. The retaining element includes one or more slots adapted to expand the element to permit insertion of the screw and deformation of the hole upon insertion of the screw, while locking the screw to retain the screw in place. This arrangement permits the elimination of the metal standoff frequently used in similar devices. Methods for preparing the assembly and mounting the printed circuit boards are also described.

Abstract: An apparatus for providing board level shielding of Electromagnetic Interference in a printed circuit board is disclosed. The apparatus includes a plastic part, a metal conformal coating and a form-in-place Electromagnetic Interference gasket. The plastic part is configured in one or more compartments to provide an enclosure, and is attached to the printed circuit board. The metal conformal coating is applied continuously to one or more surfaces of the plastic part. The form-in-place Electromagnetic Interference gasket is applied on top of the metal conformal coating in an area of a part flange.

Abstract: A sensor for detecting the presence of hydrocarbons and hydrocarbon containing fluids. It is formed of a first conductor which is formed of a metal wire or metal foil covered by an insulative sheath; a second conductor which consists of a hydrocarbon swellable elastomer and one or more conductive fillers; optionally an abuse/abrasion resistant jacket overlaying and preferably surrounding the two conductors and optionally a hydrocarbon permeable overcoat overlaying the jacket. The sensor may be in the form of a continuous length wire or a tape or a sheet. It may be coupled to an electric supply at one portion and a resistance indicator at the return portion. The resistance indicator is then attached to a signaling device such as a light or alarm.
