20100313201 | METHODS AND APPARATUS FOR FAST CONTEXT SWITCHING IN A VIRTUALIZED SYSTEM - The present disclosure provides methods and apparatus for fast context switching in a virtualized system. In the disclosed system, a globally unique application-space identifier is associated with each guest application. No two applications share the same application-space identifier, even if the two applications reside in different virtual machines. Domain identifiers are used to ensure that a guest's mappings are only active when that guest is executing. A unique domain identifier is associated with each virtual machine, and all translation lookaside buffer entries thereby mapping the guest's kernel pages with that domain value. All other mappings are tagged with a predefined domain such as zero. In addition, a virtual memory management unit may be configured to support two virtual page table pointers and a configurable boundary between a virtual user page table and a virtual kernel page table. In such an instance, the two virtual page table pointers are presented to a guest operating system, and two physical page table pointers are associated with the two virtual page table pointers. | 12-09-2010 |

20100026215 | LUMINAIRE SYSTEM AND METHOD - A device comprising a solid state or mechanical switch coupled to a first connector and a second connector and at least one lighting device such as an LED light source wherein when power is applied to the first connector, the switch is operable to direct power to the lighting device and to a portion of the pins of the second connector. By constructing the connectors as similar, but with opposite genders, the connectors can be disposed on a circuit assembly to allow for daisy chaining a series of luminaire assemblies together. The connectors may be Ethernet connectors and the switch may be operable through control signals coupled to the Ethernet connector such that a smart power controller operating using power over Ethernet (POE) can operate to control the light sources. | 02-04-2010 |
20110019396 | FIXTURE SUPPORT SYSTEM AND METHOD - A luminaire comprising a first hub comprising a first fixed portion rotatably coupled to a first rotor portion, said hub having an internal chamber, accessible through openings on the first fixed portion and the first rotor portion; a first lamp socket coupled to the first rotor portion of the first hub; a light rail affixed to the first rotor portion, said light rail having a bore the length of the light rail; a second hub comprising a second fixed portion rotatably coupled to a second rotor portion; and a second lamp socket coupled to the second rotor portion of the second hub, wherein a first set of one or more power wires is coupled to the first lamp socket, wherein a second set of power wires is disposed in the opening on the first fixed portion and further into the bore and is coupled to the second socket. | 01-27-2011 |
20110176318 | FIXTURE SUPPORT SYSTEM AND METHOD - A fixture having a cylindrical body, said body having an internal cavity extending from a first end to a second end, and said body having an exterior threaded portion, a flange affixed to the first end of the body, a portion of said flange extending past the circumference of the cylindrical body, said flange formed for receiving an electrical component, and a fastener complementary to the threaded portion, wherein the fastener and the flange are operable to secure the cylindrical body to a structure. | 07-21-2011 |

In some embodiments a portion of a sneeze guard layer operates to protect the light rail components. | 09-18-2014 |
20140268718 | LUMINAIRE MOUNTING SYSTEM - A device including a hub portion, said hub portion including an opening with spring-loaded electrical contacts slidably disposed in said opening, a light rail an extended portion and a power contact disposed on the extended portion, wherein the light rail is operable to slide into the opening and couple the power contact to the spring-loaded contact. The extended portion may include an o-ring for fixing the light rail and the hub may have a cable for mounting and coupling power to the spring-loaded electrical contact. Some embodiments may have a second opening in said hub portion, and a second end for the light rail. Power may be coupled through the light rail to hubs on each end. | 09-18-2014 |
20140268725 | SYSTEM FOR THE DISTRIBUTION OF LUMINANCE - A luminaire including a rectangular housing for housing a light source. The housing has an elongated opening for projecting the light and shutters positioned across the opening to control the light emerging from the light source through the opening. The shutters are pivotably mounted about the opening and a worm-drive is provided for setting the positions of the shutters which in-turn affects the output beam angle of the luminaire. | 09-18-2014 |
