Abstract: Modular data centers with modular components suitable for use with rack or shelf mount computing systems, for example, are disclosed. The modular center generally includes a modular computing module including an intermodal shipping container and computing systems mounted within the container and configured to be shipped and operated within the container and a temperature control system for maintaining the air temperature surrounding the computing systems. The intermodal shipping container may be configured in accordance to International Organization for Standardization (ISO) container manufacturing standards or otherwise configured with respect to height, length, width, weight, and/or lifting points of the container for transport via an intermodal transport infrastructure. The modular design enables the modules to be cost effectively built at a factory and easily transported to and deployed at a data center site.

Abstract: Apparatus and associated method and computer program products involve a highly efficient uninterruptible power distribution architecture to support modular processing units. As an illustrative example, a modular processing unit includes an corresponding uninterruptible power system in which only one AC-to-DC rectification occurs between the utility AC grid and the processing circuit (e.g., microprocessor) loads. In an illustrative data center facility, a power distribution architecture includes a modular array of rack-mountable processing units, each of which has processing circuitry to handle network-related processing tasks. Associated with each modular processing unit is an uninterruptible power supply (UPS) to supply operating power to the network processing circuitry. Each UPS includes a battery selectively connectable across a DC bus, and a AC-to-DC rectifier that converts an AC input voltage to a single output voltage on the DC bus.

Abstract: A mirror includes multiple layers, each layer having a first surface and an opposing second surface. A first layer is a cementitious material and a second layer is a material compatible with the cementitious material. A first surface of the second layer is integral to the first layer.

A first surface of the fourth layer is in direct contact with a second surface of the third layer. A fifth layer includes a transparent material. A first surface of the fifth layer is in direct contact with a second surface of the fourth layer.

The transitional member is coupled to the base member and to the mirror member. The mirror member includes a support portion coupled to the transitional member and a mirror portion.

A second bearing coupling the transitional member and the mirror member provides relative changes in elevation between the transitional member and the mirror member. A drive system rotates the transitional member about the first bearing and the mirror member about the second bearing to change the azimuth and the elevation of the mirror member.
