  • Patent number: 11569602
    Abstract: A system and flexible mounting structure for solder joint stress reduction are disclosed that provide flexibility on a printed circuit board that includes an input output (I/O) connector when wrenching or torque forces are applied. A bracket supporting the connector is mounted on one side of the PCB, and a hinge saddle structure is mounted on the other side of the PCB. A bottom structure is connected to the hinge saddle structure by screw bosses. The bottom structure and the hinge saddle structure are connected to a chassis of an information handling system. An area of the PCB as defined by the bracket is provided flexibility when forces are applied.

  • Patent number: 10319539
    Abstract: A ruggedized electronic device includes a case and an enclosure within the case. The case provides a first level of explosive atmosphere protection to components within the case. The enclosure provides a second level of explosive atmosphere protection to the components within the enclosure. The second level is higher than the first level. The enclosure includes a main board within the enclosure, and a switch. The main board includes a connection from within the enclosure to the case. The switch provides the connection to the case in a first switched mode and isolates the connection from the case in a second switched mode.

  • Patent number: 7256990
    Abstract: In a method and system for detachably docking a portable device to a docking device, the docking device is placed on a stable surface. The docking device includes a pair of moveable rear latches and moveable front latches, which are operable to latch on to corresponding matching slots of the portable device when docked. The portable device is aligned vertically on top of the docking device. A vertical force is applied on the portable device. When properly aligned a pair of alignment pins included in the docking device mate with corresponding notches on the portable device when the two devices are docked. A release latch on the docking device is operable to undock the two devices.

  • Publication number: 20040066620
    Abstract: A multiple docking system includes a portable computer having a first docking connector extending in a first direction and a docking station having a second docking connector extending in a direction substantially orthogonal to the first direction. A converter has mating interconnections for each of the first and second connectors. The converter may provide expanded functionality including floppy and CD-ROM functionality.

  • Patent number: 6505487
    Abstract: A locking device (1) includes a first clip member (20) and a second clip member (40). The first and second clip members (20, 40) include a first and second clip base (21, 41), respectively. A first jaw (22) extends outwardly from the first clip base (21) whereas a second jaw (42) extends outwardly from the second clip base (41). The first and second clip members (20, 40) are connected together so that they may move with respect to each other between a closed position and an open position. In the closed position, the first and second jaws (22, 42) cooperate to form a locking loop (6). The locking loop (6) is adapted to fit through and lock with a locking feature (32) on an object to be secured. When the first and second clip members (20, 40) are moved to the open position, the first and second jaws (22, 42) are separated by an opening.
