  • Patent number: 9036244
    Abstract: A lighting device according to another embodiment of the invention for directing source light within a source wavelength range in a blue wavelength range in a desired output direction may comprise a MEMS device that may include a DMD that includes an array of MEMS cells, each MEMS cell including an operative surface to receive and redirect the source light towards the desired output direction. The array of MEMS cells may include first and second pluralities of MEMS cells including first and second conversion coatings applied to the operative surfaces thereof configured to convert source light into first and second wavelength ranges. Furthermore, the repositionable surface of each MEMS cell may be positionable between multiple angles to reflect the converted light. The lighting device may comprise a third plurality of MEMS cells where the operative surfaces thereof is devoid of a conversion coating, or, alternatively, comprises a third conversion coating.

  • Patent number: 8918760
    Abstract: Embodiments of the present invention provide a method, system and computer program product for automated test script generation for application image validation. In an embodiment of the invention, a method of automated test script generation for application image validation is provided. The method can include parsing different modules of an existing image of a customized form of a base application to identify graphical user interface (GUI) elements in different screens of each of the different modules and cataloguing in a GUI element catalog, different GUI elements identified during parsing. The method also can include generating test scripts from the GUI element catalog. Finally, the method can include applying the generated test scripts to a new image of the customized form of the base application.

  • Patent number: 8905584
    Abstract: A lighting fixture comprising a stationary housing and a mobile housing carried by the stationary housing is provided. The lighting fixture also includes a lens carried by the mobile housing, a first rotation mechanism operatively connected to the connection rod, and a second rotation mechanism carried by the encasing member. The connection rod may protrude at least partially through the backing of the mobile housing. The first rotation mechanism may be configured to rotate the mobile housing about a first rotational axis, and the second rotation mechanism is configured to rotate the mobile housing about a second rotational axis. The mobile housing is configured to rotate about the first rotational axis such that portions of the lens are selectively positionable below a plane defined by a lower surface of the encasing member.

  • Patent number: 8899776
    Abstract: A lighting device may include a housing configured to be attached to a thoroughfare surface. The housing may include a top surface, a proximal face, a distal face, and first and second sidewalls extending between the proximal face and the distal face. Circuitry may be carried by the housing. A first primary optic may be carried by the housing adjacent the first sidewall to define a first optical chamber, and a first light source may be positioned within the first optical chamber and carried by the housing adjacent the first sidewall. The first sidewall may have a first slanted section, and an axis of the first slanted section may skew to a longitudinal axis of the lighting device.

  • Patent number: 8899775
    Abstract: A lighting device includes a housing attached to a thoroughfare surface. The housing may have a top surface, a proximal face, a distal face, and first and second opposing sidewalls extending between the proximal face and the distal face and extending downwardly from the top surface. The lighting device may further include a first primary optic that may be carried by the housing adjacent the first sidewall that may define a first optical chamber. The lighting device may also further include a first light source that may be positioned within the first optical chamber and may be carried by the housing adjacent the first sidewall. The first sidewall may taper in a direction of the distal face. The first primary optic may be configured to direct light outward and in a direction of the taper in the first sidewall.

  • Patent number: 8866839
    Abstract: A signal adapting chromacity system to control that may include a signal conversion engine to receive a source signal designating a color of light defined by a two spatial plus luminance dimensional color space, such as the xxY color space. The signal conversion engine may convert the source signal to a three dimensional color space defined within a subset gamut of a full color gamut, such as an RGW, RBW, or GBW color space. The subset gamut may include a first color light, a second color light and a high efficacy light. The signal conversion engine may perform a conversion operation to convert the source signal to an output signal, using the output signal to drive light emitting diodes (LEDs). The conversion operation may be a matrix, angular or linear conversion operation.

  • Publication number: 20140301070
    Abstract: A thoroughfare lighting device may include a housing configured to be attached to a thoroughfare surface, having a top surface, a proximal face, a distal face, and first and second opposing sidewalls, a driver circuit, a plurality of light-emitting diodes electrically coupled to the driver circuit comprising a first set of LEDs configured to emit a generally white light, and a second set of LEDs configured to emit colored light that is observable by an observer. The lighting device may also include an optic carried by the housing and positioned in optical communication with the plurality of LEDs. The color of light emitted by the second set of LEDs may be selectable to indicate a condition of the thoroughfare in a direction of travel of the observer. Additionally, the first sidewall may taper in a direction of the distal face.

  • Publication number: 20140268731
    Abstract: A low bay lighting system which may include a fixture housing and a plurality of light sources disposed on a mounting surface in the fixture housing. The low bay lighting system may also include a power supply and an optic that is configured for emission of glare-inducing wavelength light at non-glare-inducing angles. The non-glare-inducing angles may be measured from a horizontal axis running through a medial portion of the mounting surface of the fixture housing. One or more of the plurality of light sources may be configured to emit light having a wavelength range within an anti-glare wavelength range. The light emitted at glare-inducing angles may have a wavelength range substantially within the anti-glare wavelength range.

  • Publication number: 20140229923
    Abstract: A method, system and computer program product for commit sensitive testing is provided. The method includes applying a full set of different tests to an application and monitoring the application of the full set of different tests to determine files of the application affected by the full set of the different tests. The method also includes generating a mapping of each of the files and corresponding ones of the full set of the different tests affecting each of the files. Finally, the method includes responding to a change in one of the files by identifying in the mapping only a subset of the full set of the different tests affecting the changed one of the files and applying only the subset of the full set of the different tests to the changed one of the files.
