Abstract: An electrical equipment cabinet encloses a rack supporting equipment and cables connected to the electrical equipment. The rack and the cabinet define a gap between the rack and at least one side wall of the cabinet. The cabinet includes a thermal barrier fitting within the gap and defining a channel for cables. The thermal barrier includes a bracket connecting to the cabinet a channel side wall extending from the bracket, and a hinged panel connected to the channel side wall. The equipment cabinet may utilize a plurality of the thermal barriers to eliminate warm air bypass routes within the cabinet that deteriorate the cooling effect of air blowing across the equipment from front to back of the cabinet. Temperatures sensors and fens may be incorporated into the cabinet for additional temperature control. The thermal barriers and the control system may be part of a kit used retrofit existing cabinets.

Abstract: A telecommunications patching system is provided having a panel and at least one cassette movably received in the panel. The cassette receives a plurality of telecommunication jacks. The panel and cassettes are oriented horizontally. Each jack includes a front cavity adapted to receive a patch cord plug having a patch cord cable extending therefrom. The cassette has first and second ends. A cable management tab extends from the first end of the cassette so that the cassette may be readily moved to different positions in the panel.

Abstract: A dry analytical element is disclosed which can be used for the quantification of high-density lipoprotein cholesterol (HDLC). The element comprises a support having one or more reagent layers containing a first enzyme, a cholesterol ester hydrolase, to hydrolyze cholesterol esters, a second enzyme, cholesterol oxidase, to release hydrogen peroxide from cholesterol, and a third enzyme, horseradish peroxidase, to oxidize a leuco dye that is read at 670 nm. The element also contains phosphotungstic acid, a non-high-density lipoprotein precipitant, and a high-density lipoprotein selective surfactant, which together confer HDLC selectivity on the assay. Also disclosed are polymers that improve assay precision and eliminate interference from hemolyzed patient samples.
