  • Publication number: 20200117151
    Abstract: Outages and/or switching operations associated with an electrical energy distribution system (e.g., a power grid system) are managed. In an implementation, a system provides for receiving outage request information related to a request to interrupt a power supply provided to a device in an electrical energy distribution system, determining switching information related to a set of steps to de-energize a portion of the electrical energy distribution system associated with the device based on the outage request information, and performing a switching operation to de-energize the portion of the electrical energy distribution system based on the switching information.

  • Publication number: 20190392080
    Abstract: A method for filtering a set of records on a user interface involves displaying a set of records, each record of the set comprising a first field and a second field; removing, from the displayed set, one or more records according to a filter of the first field, thereby leaving a subset of the set of records displayed; displaying filters for the second field; and for at least one of the displayed filters, visually indicating that, due to a currently-applied filter, the at least one displayed filter does not apply to any of the records of the subset.

  • Publication number: 20190238826
    Abstract: In some embodiments, optical systems with a reflector and a lens proximate a light output opening of the reflector provide light output with high spatial uniformity and high efficiency. The reflectors are shaped to provide substantially angularly uniform light output and the lens is configured to transform this angularly uniform light output into spatially uniform light output. The light output may be directed into a spatial light modulator, which modulates the light to project an image.

  • Publication number: 20180252863
    Abstract: Illuminating coherent or partially coherent light may be directed over an optical fiber and may be despeckled by vibrating the optical fiber or by increasing the number of modes and modal dispersion. An exemplary embodiment is directed to an optical fiber attached to a vibrating device operable to vibrate the optical fiber above a threshold frequency. Another exemplary embodiment is directed to an optical fiber configured to have a refractive index profile operable to increase the number of modes and modal dispersion.

  • Patent number: 9897819
    Abstract: The present disclosure includes systems and methods for solving speckle problems by exciting the screen with a more complex vibration spectrum. A range of frequencies provides, in effect, a collection of overlapping patterns of high and low displacement, so that all regions of the screen have enough motion to reduce visible speckle. As previously discussed acceptable speckle may be approximately 15% contrast or less, preferably approximately 5% contrast or less at approximately 15 feet from the screen.

  • Publication number: 20170244013
    Abstract: In some embodiments, an interconnect electrical connects a light emitter to wiring on a substrate. The interconnect may be deposited by 3D printing and lays flat on the light emitter and substrate. In some embodiments, the interconnect has a generally rectangular or oval cross-sectional profile and extends above the light emitter to a height of about 50 ?m or less, or about 35 ?m or less. This small height allows close spacing between an overlying optical structure and the light emitter, thereby providing high efficiency in the injection of light from the light emitter into the optical structure, such as a light pipe.

  • Patent number: 9709883
    Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

  • Patent number: 9696617
    Abstract: The present disclosure provides discussion of screen vibration to reduce speckle in display applications and/or projection screens. Electrical transducers or reactors may be used with a screen to reduce or remove speckle in projection screens and/or display applications. Electrical transducers may not be directly mounted to a screen, thus eliminating many mechanical failure modes associated with a vibrating transducer as well as resulting in a much quieter operation. By design, the reactors or transducers may actually contact the screen, and can take up less than one square inch of screen surface each, than previous designs, which may be outside of the active viewing area and within 12 inches of the screen border, preferably less than approximately 1 inch from screen edge. The reactors are magnets, though any ferrous material can be made to work with certain operating conditions.
