  • Patent number: 11326747
    Abstract: Various examples concern techniques for opto-mechanically manipulating LED-based lighting systems. More specifically, various embodiments concern creating patterns of colored LEDs by determining the preferred color-specific density distribution and sequence(s) of LEDs. When creating the patterns, multiple considerations can be taken into account, including the power to be shared amongst the color channels when certain color models are generated by the linear array of LEDs, allocating an appropriate number of LEDs to each color channel to support the desired color spectrum, the sequencing of those LEDs along a string (e.g., as part of a linear array), etc. The appropriate number of LEDs for each color channel may be determined by first establishing the color model of the linear array within which the LEDs are interleaved.

  • Patent number: 9326147
    Abstract: An information processing device includes: a display unit that displays a display screen; an operation unit that accepts a specified operation made on the display screen of the display unit; and a control unit that causes the display unit to display an unlocking screen including an indicator corresponding to a predetermined information processing function, and controls the operation unit into a state of accepting a specified operation on the indicator, based on a request for releasing a locking function of prohibiting a predetermined specified operation from being made on the operation unit, in a state where the locking function is active. The control unit determines that an unlocking operation for releasing the locking function has been input, in a case of accepting a specified operation indicating release of the locking function on the unlocking screen via the operation unit.

  • Patent number: 9099679
    Abstract: Electronic devices, such as photovoltaic, transistor or doped light-emitting devices, can be manufactured with an air-based manufacturing process and device structure that encapsulates the device with air-stable electrodes and active layers that are reasonably stable in their unexcited state. A sheet of flexible material may act as a substrate and a second sheet of material acts as a cover. Getter materials are included in the encapsulated device, with the getter latent or unreactive during the manufacturing process.

  • Publication number: 20140197398
    Abstract: The present invention uses an isopotential source layer for an electronic device, wherein the source layer provides ions of charge to be preferentially injected into an active layer of the electronic device, such that a charge of the injected ions has the same sign as the sign of a relative bias applied to the isopotential source layer. The source layer may comprise a composite ionic dopant injection layer having at least one component that has a relatively high diffusivity for ions. The composite ionic dopant injection layer may comprise metallic conductive particles and an ion supporting matrix. The composite ionic dopant injection layer may also comprise a continuous metallic conductive network and an ion supporting matrix. The metallic network comprises metallic nanowires or conductive nanotubes. The ion supporting matrix may comprise a conductive polymer.

  • Publication number: 20140169025
    Abstract: A linear light module having an optical coupling element and a light pipe is described. The optical coupling element receives light emitted by multiple light emitting diodes (LEDs) having different emission wavelengths and couples the light efficiently to a linear light pipe. The light from the LEDs is efficiently mixed by the optical coupling element and the light pipe to produce a linear light output that is uniform in color and intensity. Diffusers can be used with the optical coupling element and light pipe at various locations to further enhance the uniformity of the emitted light.
