    Abstract: An embodiment of a power-supply module includes a package having sides, a first power-supply component disposed in the package, and an electromagnetic-interference (EMI) shield disposed adjacent to two sides of the package. For example, such a module may include component-mounting platforms (e.g., a lead frame or printed circuit board) on the top and bottom sides of the module, and these platforms may provide a level of EMI shielding specified for a particular application. Consequently, such a module may provide better EMI shielding than modules with shielding along only one side (e.g., the bottom) of the module. Moreover, if the module components are mounted to, or otherwise thermally coupled to, the shielding platforms, then the module may provide multi-side cooling of the components.

  • Patent number: 9042119
    Abstract: A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The major components and subassemblies self-interconnect by integral guide and connection features effecting “slide lock” and “snap lock” self-interconnection. The major components and subassemblies self-ground by establishing an interference fit with exposed, resilient, embossed portions of wire mesh.

  • Patent number: 9029714
    Abstract: An electromagnetically shielded enclosure that is portable and lightweight with a double perimeter entry seal. The electromagnetically shielded enclosure can be used for applications such as testing and security and can be scaled from a bench top unit to a large field deployed enclosure. The electromagnetically shielded enclosure has a novel entry seal that eliminates the electromagnetic leakage that is common around the entry areas of such enclosures. The entry seal of the electromagnetically shielded enclosure is made up of a door having a first perimeter closure material and a second perimeter closure material and an enclosure opening having a first perimeter closure and a second perimeter closure where the first perimeter closure material aligns with the first perimeter closure and the second perimeter closure material aligns with the second perimeter closure. This double perimeter entry seal provides for electromagnetic isolation within the electromagnetically shielded enclosure.
