  • Publication number: 20120188287
    Abstract: An electronic device may contain components such as a processor, video circuitry, camera flash, communications circuitry, and other components that may generate heat during operation. The device may have a display with a backlight unit that contains light-emitting diodes. Control circuitry within the electronic device can apply drive powers to the light-emitting diodes in a way that is sensitive to the operating temperature of the light-emitting diodes. The control circuitry can determine whether the temperature of the light-emitting diodes is elevated by determining which components are active in the device. Activity levels can be ascertained by gathering status information on each component. Temperature sensors may be used to make real time temperature measurements.

  • Patent number: 8154680
    Abstract: A display may be based on a display unit that is mounted within a chassis. The display unit may be a liquid crystal display unit. A backlight may be used to illuminate the display unit. The backlight may include a light guide plate. Light from a light source may be launched into an edge of the light guide plate. Scattered light from the light guide plate may travel vertically along a vertical axis that is perpendicular to the plane that contains the light guide plate. The scattered light may pass through the display unit and may serve as backlight for the display. The light guide plate may be mounted within a rectangular opening in the chassis. The edges of the rectangular opening and the edges of the light guide plate may be configured to reduce excessive reflections. These edges may have reflection-reducing coatings, non-planar surfaces, and other reflection-reducing configurations.

  • Patent number: 7773582
    Abstract: A method, apparatus and computer program product for performing dynamic Voice Over Internet Protocol (VOIP) endpoint mapping is presented. At least one on net endpoint of a VOIP call is determined. An endpoint data structure is used to store, for each on net endpoint of the call, a key and at least one of an Internet Protocol (IP) address of the end point, a phone number associated with the endpoint, and/or a display name associated with the endpoint. The endpoint data structure is used to correlate call legs across a network. Heuristics of the VOIP call are determined, the heuristics including information relating to the main source call leg and the main destination call leg.

  • Publication number: 20090202028
    Abstract: An apparatus, method, and article to dynamically adjust a data signal using a regenerated clock signal in an emulator to increase communication speed between the emulator and the evaluation board is disclosed. In one embodiment, this is achieved by applying a reference clock signal at a predetermined frequency to a digital circuit. A delayed return data signal is then sampled from the digital circuit. The sampled delayed return data signal is then compared to an expected return data signal. The delayed return data signal is then adjusted as a function of the comparison to increase the communication speed between the emulator and the evaluation board.

  • Publication number: 20080306986
    Abstract: Embodiments of the invention provide apparatuses, computer media, and methods for obtaining a rule component from a legacy application and subsequently generating an intermediate state expression from a legacy rule of the rule component. The intermediate state expression is converted to a target rule, which is utilized by the target application. Also, a data component is obtained from the legacy application, and an intermediate data element is generated from a legacy data element. The intermediate data element is converted to a target data element that may be accessed by the target application when executing the target rule. A vocabulary item is extracted from the rule component. The vocabulary item is aggregated with the intermediate state expression to form the target rule. The target rule is subsequently deployed to the target application.

  • Publication number: 20070128745
    Abstract: A phosphor deposition process and apparatus that enables an efficient, consistent, and flexible white light LED light engine by spraying a conformal coating of phosphor matrix onto an array of LEDs to achieve high color uniformity, consistency, and efficiency. A predetermined ratio of one or more phosphor powders are mixed with a support matrix (preferably silicone), the types and amounts of which are calculated to provide a predetermined spectral output. A low-viscosity carrier is introduced into the phosphor matrix to allow for further processing and deposition. The phosphor matrix and carrier mixture is atomized and sprayed in one or more uniform layers onto one or more LED devices. Computerized control, movable stages, and in-process spectral monitoring are incorporated to provide rapid and accurate processing of LED devices.
