Abstract: A system includes a stacked enclosure comprising multiple structural modules arranged in a vertically oriented stack. Each structural module is disposed at a different vertical level, and each structural module has a substantially same footprint. Each structural module is configured to house support equipment for a data center. The system also includes one or more interstitial layers disposed between adjacent structural modules.

Abstract: A lifting tower for use in the adjustment of the height of an attached structure. The tower uses rotational power means to raise and lower a lift, and an attached lifting beam, within the entire travel zone defined by vertical columns of the tower in a single stroke without the need for any intermediate recalibration of the tower. A system comprising a plurality of towers and a controller, as well as a method of use, are also disclosed.

Abstract: An avail comparator and method validates scheduled avail tones. The method includes receiving an automation playlist indicating at least one scheduled avail tone configured to be included in a broadcast. The method includes receiving a feed corresponding to the broadcast. The method includes receiving a signaling for each of the at least one scheduled avail tone based upon the automation playlist. The method includes determining whether the at least one scheduled avail tone was triggered in the broadcast based upon the corresponding signaling.

Abstract: A removable storage box cover having a bottom wall having a fore edge, at least two sidewalls having upper edges, fore edges, and defining a rectangular internal cavity, and a lid hingedly coupled to one of the at least two sidewalls, wherein the lid includes an upper wall portion having lateral side edges and a sidewall portion having lateral side edges and a lower edge separating the lateral side edges of the sidewall portion of the lid. The cover also includes a first track spanning the perimeter of the exposed edges of the at least two side walls and bottom wall and a second track spanning the perimeter of the exposed edges of the lid, wherein the lid, sidewalls and bottom wall are operable to be joined together in a watertight relationship with one another to enclose a box and be opened to insert or remove a box.

Abstract: A control and pressure relief valve for relieving pressure from an automotive vehicle interior to an atmospheric pressure outside the vehicle interior in accordance with the present invention includes a valve mounting location having an inlet in fluid communication with the vehicle interior and an outlet selectively in fluid communication with the atmospheric pressure. At least one relief valve mounted on the valve mounting location allows air to flow from the vehicle interior to atmospheric pressure when the air pressure in the vehicle interior exceeds a first predetermined pressure value that is greater than the atmospheric pressure. At least one control valve mounted on the valve mounting location allows air to flow from the vehicle interior to the atmospheric pressure when an air pressure in the vehicle interior exceeds a second predetermined pressure value that is greater than the atmospheric pressure and less than the first predetermined pressure value.

Abstract: A system is disclosed which includes a transmissive liquid crystal display of the type which may display a line of characters or symbols at a time, or which may display only a raster line in combination with an energy source and a controllable and transportable medium. The medium is exposed by energy from the source of energy passing through the liquid crystal display which acts as a mask for the source of energy. The liquid crystal display may be set by electrical signals manually generated such as by a keyboard or by signals automatically generated by use of other electronic equipment. In one alternate embodiment of the invention a large area two-dimensional liquid crystal display is used as a mask. In another embodiment of the invention a liquid crystal display is used as a mask for the purpose of exposing a photoconductive drum of the type used in xerography. A reflective liquid crystal display is disclosed in yet another embodiment of the invention.
