  • Patent number: 7649209
    Abstract: A light emitting diode is disclosed. The diode includes a package support and a semiconductor chip on the package support, with the chip including an active region that emits light in the visible portion of the spectrum. Metal contacts are in electrical communication with the chip on the package. A substantially transparent encapsulant covers the chip in the package. A phosphor in the encapsulant emits a frequency in the visible spectrum different from the frequency emitted by the chip and in response to the wavelength emitted by the chip. A display element is also disclosed that combines the light emitting diode and a planar display element. The combination includes a substantially planar display element with the light emitting diode positioned on the perimeter of the display element and with the package support directing the output of the diode substantially parallel to the plane of the display element.

  • Patent number: 7646954
    Abstract: An optical fiber telecommunications cable includes micromodules positioned with a longitudinal central cavity formed by a jacket. Two strength members are arranged longitudinally in the jacket and define a bending axis of the cable. Each strength member has an elongated oval cross-sectional shape with a height perpendicular to the bending axis and a width parallel to the bending axis. The height-to-width ratio of each strength member is more than one and no more than two. The optical fiber telecommunications cable has a reduced diameter and good robustness, and can be manufactured at lower cost.

  • Patent number: 7646024
    Abstract: A structure is disclosed that reduces the forward voltage across the interface between silicon carbide and Group III nitride layers. The structure includes a conductive silicon carbide substrate and a conductive layer of aluminum gallium nitride on the silicon carbide substrate. The aluminum gallium nitride layer has a mole fraction of aluminum that is sufficient to bring the conduction bands of the silicon carbide substrate and the aluminum gallium nitride into close proximity, but less than a mole fraction of aluminum that would render the aluminum gallium nitride layer resistive.

  • Patent number: 7646952
    Abstract: Disclosed is an optical fiber cable that includes optical fibers and a deformable coupling element enclosed within a buffer tube. The coupling element is formed from a deformable yet substantially incompressible material and features a number of raised members projecting toward the optical fibers. The design of the coupling element layer permits coupling of the optical fibers to the buffer tube without the use of a compressive cushioning layer. This arrangement distributes the compressive force applied to discrete points along the outer perimeter of the optical fiber element.
