  • Publication number: 20090002949
    Abstract: In one embodiment, an apparatus having an electromagnetic interference (EMI) shield for an electronic component. The EMI shield and the electronic component are adapted to be assembled onto a circuit board. The EMI shield provides EMI shielding for the electronic component. The EMI shield includes a thermally conductive material, such as a metal. The EMI shield is deformed, e.g., with a dimple or a tab, to form a contacting portion to contact the electronic component. After the assembly of the EMI shield and the electronic component onto the circuit board, the contacting portion of the EMI shield contacts the electronic component, thereby allowing conductive transfer of thermal energy between the electronic component and the EMI shield and enhanced heat dissipation for the electronic component.

  • Publication number: 20080040885
    Abstract: An electronics system is implemented within a compact enclosure comprising two or more hinged layers. The functionality corresponding to a shelf of a conventional cabinet resides in a corresponding layer. Backplanes are eliminated, each layer having contact surfaces that mate with matching surfaces of adjacent layers when the layers are rotated about their hinges into the closed configuration. Additional interconnection may be made through cabling housed within a special channel or compartment. Each layer may include cooling fans, which are smaller than conventional counterparts (due to shorter convection paths). Expansion may be effectuated by mating additional units of similar conformation in a modular fashion. Optionally, the functionality corresponding to a given layer may be implemented in circuitry integrated onto a single board to reduce cabling and facilitate replacement and repair. Additional functional layers may be stacked along the depth direction as well as the height or width direction.

  • Publication number: 20070229307
    Abstract: An apparatus and method are provided for detecting whether a vehicle has been altered to conceal contraband. The invention involves receiving a detected signature of sensors embedded in a vehicle, in which the detected signature is a function of i) a distinctive characteristic of the sensors embedded in areas of the vehicle, ii) a number of the sensors embedded in areas of the vehicle, and iii) locations of the sensors in the vehicle. Afterwards, the detected signature is compared to a stored reference signature to determine whether there exists at least one difference between the stored reference signature and the detected signature. If a difference exits, then an alert is produced to notify inspectors that a detailed search is required in a specific area of the vehicle.

  • Publication number: 20070009136
    Abstract: Apparatus for inspecting a vehicle in order to determine whether portions of the vehicle have been altered to conceal contraband or explosives. The apparatus captures an image of an area of a vehicle that should not be altered from a known configuration and compares the image to a reference image of the area as it should appear if it is unaltered. If the captured image and the reference image match, the vehicle is considered unaltered, and hence safe to pass. If the captured image and the reference image do not match, the vehicle is identified as likely to have been altered, and hence a candidate for further inspection. An alert is produced if at least one such difference is found.

  • Patent number: 7113410
    Abstract: An electromagnetic shield structure (100) has an elongated conductive wall (102) that continuously or discontinuously defines a shielding perimeter and has a flange (104) laying over laterally to form a J-shaped hook (106) in cross section. A conductive cover or lid (108) engages over the standing wall (102) and has a depending side wall skirt (110) that has a flange (112) and forms a J-shaped hook (114) facing opposite from the hook (106) of the elongated wall (102). The cover (108) is pressed onto the wall (102) for assembly, causing the flanges (104) and (112) to deflect and snap over one another in the space between the overlapping skirt (110) and wall (102). The shield enclosure (122) can be disassembled without damage by applying a tool (116) through an opening (118) in the outer one of either the skirt (110) or wall (102), to deflect and disengage the flanges (104) and (112) in the space between the overlapped skirt (110) and wall (102).
