A door system suitable for installation in data centers to limit airflow to and from aisles between rows of equipment cabinets has a door assembly with a door panel and a plurality of vertically spaced hinge assemblies having powerful permanent magnets manually movable between connected and disconnected positions, enabling the door assembly to be aligned and positioned on the side wall panel of an equipment cabinet and then removably mounted in place by engagement of the magnets. Each magnet can be mounted in a rotatable threaded magnet carriers received in a threaded recesses in the hinge assembly and rotation of the magnet carrier is operable to move the magnet into the connected and disconnected positions. The hinge assemblies also include registration tabs that engage slots in the cabinet for proper alignment and orientation of the door system.

A bolometric detector includes a substrate; bolometric detection microbridges suspended above the substrate and thermally insulated from the substrate; bolometric compensation microbridges suspended above the substrate and thermalized to the substrate; and a read circuit formed in the substrate to apply a biasing to the detection microbridges and to the compensation microbridges and to form differences between signals generated by detection microbridges and signals generated by compensation microbridges under the effect of the applied biasing. Each detection microbridge and each compensation microbridge includes electrically-conductive anchoring nails connected to the read circuit, a membrane attached to the anchoring nails above the substrate, and a thermometric element arranged in the membrane. The detector further includes thermal short-circuit elements between the membrane of each compensation microbridge and the substrate.

A telescopically adjustable shelf divider for dividing merchandise shelving having different front-to-back depth dimensions and non-standardized openings in the surfaces thereof. Front and back divider panels are formed by vertically spaced apart and horizontally extending panel-forming elements arranged so that the panel-forming elements of one divider panel lie in a common plane with the panel-forming elements of the other divider panel and at least one panel-forming element of one panel is slidably supported by a panel-forming element of the other divider panel. Retaining elements are fixed to panel-forming elements of one divider panel and extend vertically beyond a panel-forming element of the other divider panel to maintain the panels is overlapping, telescopically adjustable relation. Panel-mounting elements extend downward from the respective divider panels for reception in openings in the shelving surface, and a stabilizing element extends transversely from one panel to retain the divider in a vertical orientation.
