Abstract: A method and apparatus for an electronic equipment enclosure that provides a frame and an enclosure surrounding the frame. One or more plenums may be arranged between the frame and enclosure and a heat exchanger may be mounted within the one or more plenums. The heat exchanger(s) may be water-based, glycol-based, refrigerant-based or based on other liquid mediums. The heat exchanger(s) may include multiple sets of fans and cooling elements, which may form a redundant cooling configuration. The heat exchanger(s) of one or more enclosures may be interconnected to a cooling controller that may control liquid-flow and air-flow rates within the one or more enclosures based on sensor signals provided to the cooling controller.

Abstract: A method and apparatus for an electronic equipment enclosure that provides directed airflow only to those volumes within the enclosure that require the airflow. The electronic equipment enclosure further provides protection from contaminants such as falling dirt, rain, sleet, snow, windblown dust, splashing water, hose-directed water, and ice. A pedestal may be coupled to the electronic equipment enclosure that facilitates movement of the electronic equipment enclosure via a pallet jack, forklift, front loader, or similar jacking device. A sidecar may also be coupled to one or more sides of the electronic equipment enclosure to facilitate vertically mounted equipment within the sidecar.

Abstract: A method and apparatus for an adaptive, multi-axis suspension support system providing both coarse and fine suspension to a payload. Coarse suspension control is provided to maintain the payload within a coarse range of position. Fine suspension control is provided by monitoring and analyzing vibration characteristics in both time and frequency domains to determine the required amount of damper resistance to be exerted by a magnetorheological (MR) device.

Abstract: A method and apparatus for a close-coupled cooling system provides an equipment rack that includes at least one heat exchanger in close proximity to electrical components contained within the equipment rack. The heat exchanger receives inlet water at a selected temperature to adjust a cooling capacity of the heat exchanger to maintain an adequate cooling capacity of the heat exchanger to reject heat generated within the equipment rack. Exhaust water from the heat exchanger may be cooled by a heat rejection source, blended with cooled water from a heat rejection source, and/or blended with cooled water from the heat rejection source and a chiller to achieve the desired inlet water temperature to the heat exchanger. A substantially zero-bypass, differential pressure air-flow system may be used in conjunction with the heat exchanger to further adjust a cooling capacity of the heat exchanger.

Abstract: A method and apparatus for a low-profile suspension system, which provides coarse and fine suspension control to an object supported by the low-profile suspension system. Coarse suspension is provided to adaptively control a position of the object through pneumatic support devices. Pneumatic pressure is adaptively increased in the pneumatic support devices to support an increasing weight of the object, while pneumatic pressure is adaptively decreased in the pneumatic support devices to support a decreasing weight of the object. Fine suspension control is provided through rotational actuation of a shock absorbing device through a right-angle gear drive. By rotationally actuating the shock absorbing device, a range of stroke of the shock absorbing device along a vertical direction is minimized. Position equalization control is further provided to maintain a position of the object along an axis that is orthogonal to the coarse and fine suspension axis.

Abstract: A method and apparatus for a pneumatically sprung caster mechanism to provide a pneumatically controlled ride height for a platform attached to the caster. The caster is mounted to a first end of a pivoting axle, while a piston is mounted to the opposite end of the pivoting axle. The length of the piston is pneumatically controlled to rotate the pivoting axle to either increase, or decrease, the distance between the caster and the platform. Suspension is provided through interaction of the piston with an air reservoir, whereby minute variations in the length of the piston are absorbed by the elasticity of the walls of the air reservoir. A free-flow of air is facilitated such that air forced out of the piston during contraction may be collected by the air reservoir and air required by the piston during expansion may be provided by the air reservoir.

Abstract: A method and apparatus for an electronic equipment rack that provides mobility through directional self-propulsion and multi-axis suspension. The electronic equipment rack further provides self-powered operation and environmental control with wireless access, while protecting against unauthorized access, electromagnetic interference (EMI), and dust contamination. An alternate embodiment provides a non-mobile electronic equipment rack with multi-axis suspension, while optionally providing wireless access and protection against unauthorized access and the environment.
