  • Patent number: 11690154
    Abstract: An network addressable lighting device that receives the input power from a power source (PSE), such as a network Power Over Ethernet (PoE) source, at a physical interface and data assembly PIDA and passes the signal directly to a second power assembly (PA) while the AC coupled high-speed data lines stay exclusively on the PIDA that contains the input and output physical interfaces, such as RJ interfaces. All power rails required to run the PIDA are converted on the PA and can then be sent back to the PIDA via low-cost conventional board stacker connectors. Movement of the high-current is done on the power assembly and not the data assembly where the sensitive communications primarily occur. The implementations thus provide an ideal separation of power and data structures to reduce EMI/EMC issues in a low cost and compact device.

  • Patent number: 11310319
    Abstract: A control system for controlling a networked system of multiple individually addressable devices, such as lighting devices, each having a logical address based on a network addressing scheme, each lighting device being connected to a computer network through a cable that transmits electric power for powering one or more lighting elements of the lighting device and hierarchical control data for addressing and controlling the lighting device. Each lighting device includes a controller for receiving the hierarchical control data and controlling a state of the one or more lighting elements in accordance with the control data.

  • Publication number: 20090138979
    Abstract: The observed over-expression of Sp1 target genes has inspired inventors to formulate a specific strategy for correcting many gene expression defects, and thus improve clone development. The invention is based on the belief that manipulating Sp1 activity can improve cloning. Inventors believe that cloning is inefficient in large part because of the continued expression of Sp1 target genes in the early cloned embryos, which causes clones to be very unlike normal embryos, and so makes them very unhealthy. Inventors propose that if over-expression of Sp1 target genes is prevented in early stage clones, this would greatly improve cloning efficiency by making the cloned embryos healthy again.

  • Patent number: 6698066
    Abstract: A method and apparatus for conditioning a fibrous material. The conditioning arrangement includes a moisturizing chamber having two series of opposed rollers arranged to accept a fiber batt into a pressing space therebetween. The pressing space tapers from a batt entrance toward a batt exit. This tapered configuration is affected for compressing a fiber batt as it is rolled therethrough. As illustrated, before entering the conditioner, the cotton batt has a greater thickness than after compaction and processing through the moisturizing chamber. A moisture infusion assembly is provided within the moisturizing chamber and has an air distributor configured to dispense moisture laden air adjacent to a fiber batt being processed through the pressing space. An air collector is configured to pull exhaust air away from the fiber batt being processed through the pressing space.
