Electronic circuit card mounting assemblies and methods are disclosed. An electronic circuit card and an electronic equipment system include mating connectors to operatively couple the circuit card to the equipment system. The circuit card and the equipment system also include respective mating elements of a mounting assembly that engage each other to releasably mount the electronic circuit card to the electronic equipment system. The connectors and the elements of the mounting assembly are positioned to releasably hold the connectors in an operative position when the circuit card is mounted to the equipment system. Related methods of manufacturing electronic circuit cards and equipment systems are also provided. In one embodiment, the mounting assembly elements include a key and a socket to receive the key, and the key and the socket control one or more of a circuit card insertion force, a circuit card retention force, and a circuit removal force.

The invention relates to apparatus and method for efficiently removing humidity from a chamber. A thermoelectric cooler with a maintained temperature differential between the cool and warm sides of the cooler is used to condense the humidity from within the chamber upon the cool side of the cooler. The condensate is transferred to the warm side of the cooler and then removed through the capillary penetration into a porous structure of an evaporator at the warm side of the cooler and further evaporation. During evaporation, the condensate extracts heat from the warm side of the cooler, the temperature of the cool side of the cooler being also decreased, which results in an increase of the overall efficiency of the apparatus.

An apparatus for cooling an array of integrated circuit chips mounted on a substrate comprises a thermally conductive cooling plate which has a plurality of integral, substantially parallel, closed-end channels. A cover which may be made of plastic is adapted to seal the periphery of the cooling member and is spaced from the channel-containing surface. The cover has a plurality of integral baffles extending toward the cooling member into and along the length of the channels. The baffles and the channels are spaced from each other to permit passage of a coolant between and through the channels in a flow direction normal to the channels. An inlet and outlet for the coolant are provided on opposite ends of the apparatus, and may be located in the cover. In an alternate embodiment, the cooling plate contains at least two sets of the channels, each set of channels receiving a separate flow of coolant, either in parallel or in series with each other.

An environmental protection housing for an optical fiber connector having two housing parts to define an environmentally protected chamber to house the connector. The housing is for use for housing a connector upon suspended cable. So as to prevent the weight of the cable being taken by the connector when the housing parts are separated, a movement limiting device is provided an which extends between the housing members. This movement limiting device comprises an elongate rigid member which is capable of preventing relative rotation or change in relative orientation of the housing parts while the rigid member extends between the housing parts. With the connector uncoupled and thus the danger of the loading of the cable being taken upon the connector in coupled condition, the connector is releasable from one or both of the housing parts.

An integrated circuit thermal conduction module comprises a substrate having a chip-carrying surface and at least one integrated circuit chip on the substrate. A deformable, liquid-impermeable, thermally conductive film or foil extends over an upper surface of the chip. A piston has a lower surface which urges and conforms the film against the chip upper surface and which contains at least one open channel permitting coolant passage and contact with the film for conveying heat from the chip without direct contact between the coolant and chip. Preferably, the piston has a central passageway extending along the longitudinal axis for channeling the coolant through the piston, and has a plurality of channels extending radially outwardly from the central passageway along the lower face for directing coolant beneath the piston.
