An apparatus for cooling a heat-generating component is disclosed. The apparatus includes a cooling chamber containing a liquid metal. The cooling chamber has a heat-conducting wall thermally coupled to the heat-generating component. A plurality of extendable tubes making up an array of cooling pin fins is attached to the cooling chamber. Each of the extendable tubes has a port end that opens into the cooling chamber and a sealed end that projects away from the cooling chamber. Moreover, each of the extendable tubes has an extended position when filled with liquid metal from the cooling chamber and a retracted position when emptied of the liquid metal. A pump system is included for urging the liquid metal from the cooling chamber into the plurality of extendable tubes.

An assembly for dissipating heat generated by electronic components which include a ventilating panel having a plurality of vent holes arranged thereon. More specifically, the perforation pattern of vent holes is staggered to provide adjacent larger and smaller vent holes in at least two rows of vent holes. A second row of vent holes is staggered with respect to the first row of vent holes such that the larger vent holes are aligned with smaller vent holes, preferably in a ratio of two smaller vent holes per one larger vent hole. Such a perforation arrangement of vent holes may be provided on a blindswap cassette for securing and aligning computer cards for mounting in a housing, such as a sled for use in computer systems.

In one embodiment, this invention is about stacking of sheeted material after cuts. The patterns on the separate sheets are aligned for cuts to create through-holes in the stack. The cut material is not removed but simply bent back to form walls for the hole. The materials are pierced and stacked to form holes. Any additional extended walls to the hole can be formed just by adding an additional layer. One embodiment may be just 2 walls that form a 90 degree angle with respect to one another. The extended walls can be slightly bent along their lengths in order to increase their strengths and to ensure their perpendicular standing on the layers. In other embodiments, the extended walls can be equipped with extra features, such as latches, to secure the adjacent extended walls and ensure a 90 degree angle between them.

A method, apparatus, and a localized in-line cable filter system are provided for implementing electromagnetic cable noise suppression. The localized in-line cable filter system includes at least one electromagnetic interference (EMI) filter element connected between a cable and a current return path. An insulation displacement terminal connects the EMI filter element to the cable. The EMI filter element and current return path provide a low impedance connection toward a source.

A device and method for clamping and grounding a cable, includes a conductive cable clamp. The clamp is adapted to clamp and conductively engage a periphery of a conductive shield of the cable. In one aspect of the invention, the cable clamp includes a first conductive plate and a second conductive plate. Each of the plates has at least one groove formed therein. The first plate is positionable against the second plate so that the groove in the first plate and the groove in the second plate collectively form a hole extending from one edge of the cable clamp to an opposite edge of the cable clamp, with the hole accommodating the cable therein. In another aspect of the invention, the cable clamp includes a conductive flexible fabric having at least one pattern formed therein, with the pattern accommodating the cable therein.

Structures are provided for implementing an integrated conductor and capacitor in a surface mounted device (SMD) package. A first pair and a second pair of contacts contained within the SMD package respectively are provided in mating engagement with a first pair and a second pair of corresponding SMD package contacts. A conductor extends between the first pair of contacts, contained within the SMD package. A capacitor is defined between the second pair of contacts, contained within the SMD package. An additional one or pair of integral capacitors optionally is provided for providing additional capacitance to ground to decouple common mode noise from the power planes.

A device for piercing a cable includes a first clamp member and a second clamp member. The first clamp member and the second clamp member are superposed relative to each other. A conductive piercing member is disposed on the first clamp member. The device further includes an arrangement for moving the first clamp member and the second clamp member together. As the first clamp member and the second clamp member are moved together, a distance between the conductive piercing member and the second clamp member is reduced.
