Abstract: A layered screen printed conductive pattern is applied to a flexible surface for defrosting, such as in windows. A narrowed buss pattern coupled to a hexagonal grid of conductive silver is applied to vinyl to heat and defrost.

Abstract: A method for making an electrically shielded housing for an electrical device includes the steps of at least partially forming an insert member having a non-conductive outer surface portion and a conductive inner surface portion, insert molding the at least partially formed insert member in a cavity of a non-conductive housing body member so that the conductive inner surface portion of the insert member is disposed adjacent an outer surface portion of the body member cavity and the non-conductive outer surface portion of the insert member forms a housing cavity. An electrical device received in the housing cavity is electrically shielded by the conductive inner surface portion of the insert member and insulated from the conductive inner surface portion of the insert member by the non-conductive outer surface portion thereof.

Abstract: An electrically shielded housing for an electrical device and method therefor having an insert member disposed in a cavity of a non-conductive housing body member. The insert member includes a conductive inner surface portion disposed adjacent an outer surface portion of the body member cavity. A non-conductive outer surface portion of the insert member forms a housing cavity for receiving an electrical device. The conductive inner surface portion of the insert member at least partially electrically shields the electrical device, and the non-conductive outer surface portion of the insert member insulates the electrical device from the conductive inner surface portion thereof.

Abstract: A method is provided for fabricating resin-filled components, which comprises a multi-element arrangement of a thermoformed plastic sheet with a "second-surface" screen-printed graphic, which formed sheet can receive a light-directing apparatus, and the molded-resin is applied so as to secure the apparatus and provide stability to the overall structure or component. The method is particularly adapted with respect to the fabrication of graphic-display illuminated buttons for use within automotive vehicles.

Abstract: Apparatus is disclosed for thermoforming a thermoformable sheet material into a predetermined thermoformed shape. A graphic display is provided upon one side of the thermoformable sheet material, and the apparatus includes first and second die members between which the thermoformable sheet material is secured. A forming cavity is defined within the first die member for accommodating a portion of the thermoformable sheet material when the thermoformable sheet material portion is forced into the forming cavity, and the second die member is provided with a heating plate for heating the thermoformable sheet material to a predetermined temperature in preparation for the thermoforming formation of the thermoformable sheet material into the thermoformed shape within the forming cavity of the first die member.

Abstract: A dielectric panel is provided for a keyboard in an electric device, such as a telephone, to block a disruptive high voltage charge of static electricity from passing from a human operator to the device. The panel comprises an electrically non-conductive clear slightly flexible plastic planar member and a dielectric coating or ink layer adhering to the underside of the planar member. The coating is applied by a screening process while in the liquid state and is then heat-dried. The coating comprises a mixture of clear polyester plastic (initially in a liquid state but hardened when dry), powdered aluminum, and a catalyst or agent which causes the powdered aluminum particles to be uniformly distributed and suspended in the plastic while the coating is being applied and hardened. The evenly distributed particles are electrically insulated from one another in the hardened coating to thereby improve the dielectric strength of the coating and panel.
