  • Patent number: 6658700
    Abstract: A hinged-bezel system for use with electronic devices housed in equipment enclosures. The system, comprising a comb, a clamp plate, and a hinged bezel, extends the pivot of a hinge outward from the face of a equipment enclosure to allow full access to components within the equipment enclosure, through the front face of the equipment enclosure, without removing the hinged bezel. Additionally, the system allows the electronic device to be fully anchored to the equipment enclosure. The comb, mounted to the front face of the equipment enclosure, securely fastens to the clamp plate, which is attached to the front sidewall of the electronic device along with the hinged bezel.

  • Patent number: 6625018
    Abstract: A fluid-flow balancer mimics the air-flow resistance of a component omitted from an electronic system so that omission causes little or no disruption to or alteration of the flow of a cooling fluid. This prevents overheating that such disruption or alteration may otherwise cause. In addition, the fluid-flow balancer may also mimic the EMI suppression characteristics of the omitted component. Thus, a system not fully populated with components can still be adequately cooled and shielded without changing the cooling or shielding systems.

  • Patent number: 6608766
    Abstract: A bezel that includes a number of unitary EMI-shield-and-snap-retention features molded onto an inner surface of a bezel. The EMI-shield-and-snap-retention features partially fasten an EMI shield to the bezel, while also fastening the bezel to a snap attached to an equipment enclosure. Each feature contains two flanged and tapered guide strips flanking one or more ramp-shaped pieces. As the EMI shield is placed flat along the interior of the bezel, the flanged sections of the guide strips lie over top of the EMI shield, pressing the EMI shield against the interior of the bezel. As the bezel closes against the equipment enclosure, the tapered sections of the guide strips guide the snap up the ramp-shaped pieces. The snap gains tension ascending the ramp-shaped pieces. When the snap crests the ramps, tension is released in the snap, causing the convex tip of the snap to stay secured to the ramp-shaped pieces.

  • Patent number: 6590784
    Abstract: A combination of EMI-shield-retention features molded onto a bezel for an equipment enclosure. The features collectively fasten a notched and cutout EMI shield to the inner surface of the bezel without requiring any tools or fasteners. Several −Z-retention features provide surfaces for the EMI shield to lie flat against the inner surface of the bezel, while several X, Y-retention features protrude through holes and notches cut in the EMI shield to further retain the EMI shield. Finally, +Z-retention features along one edge of the bezel provide flanges for the EMI shield to slide under, while +Z-retention features, on the opposite edge of the bezel from the flanges, snap over top of the EMI shield.
