Abstract: A lighting apparatus comprises a light panel having a panel frame, and a plurality of LEDs or other light elements secured to the panel frame. Lenses and/or filters are adjusted in distance from the light elements, by for example moving the lenses/filters into different slot positions of the frame, to alter characteristics of the emitted light. Focal lenses, diffusion lenses, and color filters may be used individually or in combination. A compound lens includes lens elements having different characteristics arranged in a pattern. Through groupwise control of the intensity of the light elements, the different characteristics are emphasized or de-emphasized. The light panel may have an integrated battery, and may be mounted on a stand. The panel may be modular, allowing larger panels to be constructed from smaller panels.

Abstract: A computer-based apparatus for searching confidential documents, including a computer with a memory element and a processor to execute instructions stored in the memory to receive a confidential document and related non-confidential information from a source entity. The processor executes the instructions to: store the confidential document and non-confidential information in the memory element; and restrict access to the confidential document stored in the memory element to the source entity and a library entity only, or to the first source entity only. The processor executes the computer readable instructions to: receive a search request from a searching entity including a search parameter; identify the search parameter as being applicable to the confidential document; and transmit for access by the searching entity, the non-confidential information. The library entity is different from the source entity.

Abstract: A trim valve includes a valve housing having an inlet section and an outlet section. A valve shaft is mounted to the valve housing to be stationary with respect thereto. The valve shaft includes an internal flow passage in fluid communication with the outlet section of the valve housing. A valve rotor is disposed inboard of the valve housing and outboard of the valve shaft for modulating flow through the valve housing. The valve rotor is mounted for rotational movement within the valve housing between a fully open position in which a flow path is defined between the inlet and outlet sections of the valve housing, and a reduced flow position in which the valve rotor at least partially blocks the flow path. An actuator is operatively connected to the valve housing to actuate the valve rotor between the fully open and reduced flow positions.

Abstract: The present disclosure provides methods of using quantum dots or Q dots or a similar nanocrystal to transfer, for example, excess LED light energy in the blue band to the red band where such LEDs tend to be deficient. This approach would balance the overall spectrum of the LED without a corresponding loss in brightness as would be the case where the light from the LED was passed through a conventional filter. The Q dots could be applied to the lens portion of the LED after the high temperature processes are completed or coated to a clear filter to be placed in the LED light path.
