Abstract:

An enclosure arrangement includes a chassis, and a central electronics complex. The central electronics complex has a cage removably positioned within the chassis. The cage has an open top providing access into the interior of the cage. The central electronics complex also includes a backplane arranged in a horizontal position, and forming a floor of the cage. The backplane has at least one card slot on a surface thereof. The central electronics complex further includes at least one circuit board disposed in the interior of the cage and being removably received by the card slot. The circuit board is arranged in a vertical position so that a gravitational force helps retain the circuit board in the card slot. The cage is removably positioned within the chassis. At least one rail connects the cage to the chassis.

International Classification:

H01R 1362

US Classification:

439327

Abstract:

A bracket/collar is disclosed to circumscribe an integrated circuit card into an electrical or an optical connector. The bracket/collar has several features, such as grooves, to hold the circuit card into the bracket; the grooves may be on any available edge not mating with or held by the connector, and may hold a corner or other feature of the circuit card. Another feature of the bracket/collar is a mechanism, such as a hook or notch, to connect with the connector. Yet another feature of the bracket/collar is that, by its shape, it provides sufficient loading of the circuit card into the connector so that when dropped or otherwise mechanically shocked, the circuit card is not displaced from its connector. The bracket/collar is especially useful to secure DIMM memory cards within their electrical connectors in handheld computers.

International Classification:

H05K 720

US Classification:

361687, 361712, 165 804, 174 152

Abstract:

A computer comprises a chassis having an inner surface and an outer surface and a processing device contained within the chassis. A portion of the chassis inner surface is positioned proximate to the processing device, and a sheet of thermally conductive interface material is positioned between and contacts the processing device and the inner surface portion to thermally couple the processing device to the chassis so that the heat generated by the processing device is delivered to the chassis. The outer surface of the chassis is configured, such as with fins, for dissipating heat from the chassis. A phase-change material is positioned on the inner surface of the chassis and absorbs heat to further assist the chassis in heat dissipation.

International Classification:

US Classification:

3122933, 361798, 361801, 439157, 439923

Abstract:

A cover is operable to seat and unseat electronic components. The cover is detached from an enclosure exposing an access opening. An electronic component, such as an expansion card, is inserted by an operator into guide rails housed within the opening. A first catch mechanism of the cover pivotally engages the opening so as to form a lever arm. A second catch mechanism connects with a mating catch of the electronic component. The component traverses the guide rails according to the rotation of the cover. The mechanical advantage realized by the cover overcomes the forces associated with seating and detaching connector pins of the electronic component with sockets of an expansion bus. The cover detaches from both the component and the enclosure prior to being repositioned to overlap the opening.

International Classification:

H05K 718

US Classification:

3122232, 312296, 292 87

Abstract:

A chassis for a computer, computer related or other electronic device includes a door that closes an access opening in the chassis when in the closed position and permits access to the interior of the chassis when opened for a user or service technician. A latch releasably secures the door in the closed position and is operable by a user or service technician for opening the door from the closed position and closing the door from the open position without the benefit of a screwdriver, wrench or other tool. In selected embodiments, the latch is biased to account for compression reaction forces of a seal or gasket surrounding the access opening while still providing for manual manipulation of the door and access to the interior of the chassis.

International Classification:

G08B 17/02

US Classification:

340590, 3405682

Abstract:

A tamper sensing circuit is provided for an electrical device wherein an enclosure may be opened to access data by a user that does not possess the ability to achieve normal access by satisfying data security measures such as use of a password. A screw used to secure enclosure halves together is connected by a conductive coating at the enclosure member surface into which the screw is threaded to connect a tamper sensing circuit to the device ground potential. A tamper sensing circuit output node is maintained at the circuit ground potential as long as the screw is in electrical contact with the enclosure conductive coating. When the screw is disengaged from the enclosure member threaded opening, the output node is no longer grounded and rises to a supplied electrical potential indicating tampering and enabling appropriate corrective action. The conductive coating on the enclosure member which connects the screw to circuit ground may be applied or may already be present to suppress electromagnetic interference.

US Classification:

429/097000, 429/123000

Abstract:

A battery latch for a portable electronic device is made of a resilient material and includes integral spring members that make the use of a separate steel spring unnecessary. The battery latch is low-profile, allowing it to be easily integrated into a housing with limited space. The battery latch includes protruding members that are biased by the integral spring members into a recess that is designed to receive the battery pack. The protruding members include a beveled or curved surface that the battery pack presses against when the battery pack is being pressed into place. The force of the battery pack overcomes the bias of the integral spring members and forces the battery latch into the housing, thereby making room for the battery pack to slide past the protruding members of the battery latch. The battery pack includes recesses that align with the protruding members of the battery latch once the battery pack is fully seated in the housing. As the battery pack is fully seated in the housing, the integral spring members push the protruding members into the recesses in the battery pack, thereby holding the battery pack in place. The battery latch includes a slide button that allows a user to disengage the battery latch from the battery pack so the battery pack can be removed from the housing. The battery latch can be assembled into a housing using no tools by simply snapping the slide button through a hole in the housing into the battery latch that is placed inside the housing.
