  • Patent number: 8693204
    Abstract: Multi-purpose cowling structures are provided to minimize spacing impact within an electronic device, while maximizing functional utility. In one embodiment, an electromagnetic interference shield may provide one or more anchors for enabling a logic board cowling to apply sufficient downward force to one or more board connectors to prevent inadvertent disconnects. In another embodiment, a cowling can electrically connect the ground plane of a logic board to the ground plane of a housing member and provide a pre-load force to a conductor connection existing on logic board. A compass mounted on a flexible printed circuit board is also provided. Mounting the compass on a flexible printed circuit board enables the compass to be mounted remote from ferrous object that may affect the compass's performance.

  • Patent number: 8619435
    Abstract: An external EMI diverting structure to electrically shield an electronic device from EMI is presented. The electronic device is physically isolated from the case ground which interrupts the EMI or lightning fault path. This shield provides a return path to ground for the EMI away from the electronic device and replaces conventional EMI filter capacitors, which are not connected to case ground. The external EMI diverter comprises a first conducting enclosure enclosing the electrical circuit and is electrically coupled to the electric circuit and a second conducting enclosure enclosing the first conducting enclosure and being electrically isolated from the first conducting enclosure and the electric circuit. The diverter is physically and electrically connected to the case ground at an attachment point.

  • Patent number: 8587952
    Abstract: Insulating ribs are formed into one or more portions of a housing that encloses circuitry of an electrical device. Components mounted on a board are separated according to whether they are related to a primary side of a power transformer or a secondary side. Primary related components are typically mounted on the primary side of an isolation slot formed into a circuit board and components related to the secondary are mounted on the other side. The insulating ribs are strategically placed to protrude through the slots when circuit board is mounted to the housing portion. Thus, when the housing portion is joined to another housing portion, which also may include insulating ribs strategically placed, the ribs increase the breakdown voltage of the boundary.
