Abstract: A wireless charging coil is provided herein. The wireless charging coil comprising a first stamped coil having a first spiral trace, the first spiral trace defining a first space between windings, and a second stamped coil having a second spiral trace, the second spiral trace defining a second space between windings, wherein the first stamped coil and second stamped coil are planar to and interconnected with one another, such that the first stamped coil is positioned within the second space of the second stamped coil, and the second stamped coil is positioned within the first space of the first stamped coil.

Abstract: An improvement in the manufacture of radio frequency identification tags employs an antenna stamped from a thin metallic sheet and affixed to a substrate at a first location to establish an intermediate product in which the stamped antenna is affixed to the substrate, and the intermediate product is placed at at least one subsequent location for further processing toward completion of a radio frequency identification tag.

Abstract: A shielding enclosure has an access opening for enabling selective access to a component placed in the shielding enclosure, a closure member and a connector section selectively expansible and contractible to enable the closure member to be captured within the access opening upon expansion of the connecting section to complete shielding of the component and to be disengaged from the access opening upon contraction of the connecting section. In the preferred construction, the connecting section is in the form of a perforated web having beams oriented oblique to the directions of expansion and contraction, and the shielding enclosure is made in one piece from a single blank of shielding material.

Abstract: A smart card reader includes a housing having a rectangular plan configuration and housing members secured together by sets of complementary overlapping tabs located at the four corners of the rectangular housing and joined together, as by welding. Some of the sets include locator elements on one of the tabs of the set for locating the overlapped tabs accurately relative to one another to assure accurate dimensions in the completed housing. A stiffener plate is secured to at least one of the housing members, as by welding at spaced apart locations along the stiffener plate, to add stiffness to the housing. A lead-in ramp assists in leading the smart card from an inlet section of the reader into an intermediate section of the reader for connection to an electrical connector located in a connector section of the reader.

Abstract: A card cage shielding contactor for being interposed between a circuit card bracket and a computer chassis to enhance an electrical shielding connection between the circuit card bracket and the computer chassis when the card cage bracket is juxtaposed with the computer chassis, the card cage shielding contactor including a relatively thin, flexible sheet of electrically conductive material having a multiplicity of contactors in the form of resiliently deflectable fingers located along bands in the sheet and projecting from the bands to establish contact forces enhancing electrical shielding contact between the circuit card bracket and the computer chassis through the card cage shielding contactor.

Abstract: Method for completing personal computer cards of prescribed accurate dimensions includes nesting side walls with side channels and end walls with end channels to close an enclosure of a personal computer card and then qualifying, or conforming, the dimensions of the closed enclosure to the prescribed dimensions of the personal computer card by forming the nested walls and channels, preferably by impacting the nested walls and channels within forming dies, to attain the critical length, width and thickness prescribed for the personal computer card.

Abstract: A grounding clamp for grounding a ground wire to a grounding rod includes a strap, a segment of which is to be looped around the grounding rod and secured and connected electrically to the grounding rod by a stud having a head for passing through a selected one of a plurality of slots in the strap, spaced along the length of the strap, and a screw-threaded end for passing through a hole in a confronting portion of the looped segment of the strap for engagement by a nut which may be operated to draw the stud in a direction tending to close the looped segment, the head including an opening for receiving the ground wire outside the looped segment such that upon operating the nut to draw the stud in the direction tending to close the looped segment, the ground wire will be clamped against the strap in direct electrical contact with the strap.

Abstract: A cable shield grounding clamp connector includes an outer plate for seating upon the insulating jacket of a shielded electrical cable and an inner plate for interposition between the inner core of insulated conductors of the cable and the shield of the cable, the outer plate being curved to conform to the outer diameter of the cable and the inner plate being resiliently deflectable relative to the outer plate so as to be urged toward conformance with the curvature of the outer plate upon clamping of the jacket and the shield between the outer plate and the inner plate, the inner plate having sharp-edged teeth arranged in longitudinal rows along laterally opposite edges of the inner plate for scraping away a corrosion-inhibiting coating on the shield in response to deflection of the inner plate to expose the shield for direct electrical contact between the inner plate and the shield.
