Abstract: A method of electrical isolation for printed circuit board gasketing is disclosed for enabling gasketing to overlay plated through holes without shorting out thereto. The method of electrical isolation for printed circuit board gasketing includes counterboring at a controlled width to a controlled depth those plated through holes underlying the gasketing. The method provides the advantage of being able to overlay gasketing on both surfaces of a printed circuit board mid-plane. The method of electrical isolation for printed circuit board gasketing is particularly useful for overcoming the additional material requirements and processing steps of electrical isolation known in the art.

Abstract: A pluggable electronic module is provided that has an electronic component and a module body enclosing the electronic component. The module body has a first surface and a second surface. The first surface has a first area substantially parallel to the second surface and a second area that defines a non-zero angle with respect to the first area. The second area contacts a thermal sink to dissipate heat generated by the electronic component. The pluggable electronic module has a reduced insertion force in comparison with conventional pluggable electronic modules.

Abstract: An optical networking circuit pack is described. The circuit pack houses a plurality of pluggable electronic modules and includes an enclosure panel, a plurality of module identifiers, and a fiber management assembly. The enclosure panel has at least two collinear openings to receive electronic modules. The module identifiers reside on the enclosure panel and are proximate to a respective opening. Each module identifier is oriented at an angle with respect to an edge of the enclosure panel to facilitate association of pluggable electronic module with the respective opening regardless of whether the circuit pack is oriented in a horizontal position or a vertical position. The fiber management assembly is disposed at an end of the circuit pack to facilitate routing of optical fibers.

Abstract: A fiber management apparatus. The apparatus has a housing having a top panel, a bottom panel opposite the top panel, a back panel between the top and bottom panels, and a front panel hinged to an edge of the top panel. The front panel rotates between an open position and a closed position. The apparatus also has opposite open ends that are defined by the panels. The open ends allow optical fiber to pass through the housing. The apparatus includes a first cellular element and a second cellular element. The first cellular element is attached to an inner surface of the back panel. The second cellular element is attached to an inner surface of the front panel.

Abstract: A front installable guide for a circuit card connecting device is provided. The connecting device has a circuit card connector. The guide has a pair of elongated alignment pins. Each of the pins terminates in a fastener for attachment to the connecting device adjacent the connector. The guide also has a guiding member. The guiding member has a groove which is slidably engagable with an edge of a circuit card. A pair of parallel channels is formed in the guiding member for reception of the alignment pins such that when the alignment pins are received in the channels and attached to the connecting device, the groove is aligned for reception of a circuit card to be connected to the connecting device. The guiding member can provide support for the received circuit card.

Abstract: A hinged computer case that can be mounted to the underside of a desk surface directly in front of and hidden from its user and accommodates the ergonomic requirements of the user is described. All peripheral devices meant for user access are located in a flat drive bay, which also forms an adjustable keyboard tray, while the non-access devices are located in a CPU enclosure. In the stow-away position, the computer case hangs from a pair of guide rails with the cable connectors facing up, for easy installation. In the operational position, the computer case pivots 90° and slides on the guide rails. The flat drive bay that supports the keyboard tray s pivotally attached to the CPU enclosure by means of a cable hinge assembly. The hinge assembly enables positioning of the keyboard at a suitable angle for a respective user, and also accommodates the cables between the two enclosures.
