  • Light-emitting device, display device, and stress sensor
    Patent number: 7408297
    Abstract: A stacked structure (1) includes an electrostriction layer (2) including an electric inductive distortion material and a stress light-emitting layer (3) including a stress light-emitting material. When applying a voltage to the electrostriction layer (2) in the stacked structure (1), the electric inductive distortion material deforms, thereby the electrostriction layer (2) deforms. The deformation of the electrostriction layer (2) causes an external force to act on the stress light-emitting material of the stress light-emitting layer (3), and the stress light-emitting layer (3) emits light, accordingly. That is, by applying the voltage to the stacked structure (1), the stacked structure (1) can emit the light.

  • Apparatus and method of clock recovery for sampling analog signals
    Patent number: 7409030
    Abstract: A clock and phase detect algorithm detects the best sample result for back-end system to recover the sample clock from front-end system. The algorithm of the present invention gets the sample result from ADC by applying slope variation sum (SPVS), which is used in turning points of sample result. The exact sample clock will always get the maximum SPVS value no matter how special or difficult the pattern is. It can detect not only most of normal patterns, but also the special patterns like block, linear piece pattern. The use of SPVS result allows back-end systems to distinguish which clock is the exact clock to sample the analog signal, and make the back-end convert quality is almost the same as the front-end. This function can be operated by system maker and maintain the quality of display automatically, no manual operation is need.

  • Micromechanical Device with Microfluidic Lubricant Channel
    Publication number: 20080179696
    Abstract: A micromechanical device assembly includes a micromechanical device enclosed within a processing region and a lubricant channel formed through an interior wall of the processing region and in fluid communication with the processing region. Lubricant is injected into the lubricant channel via capillary forces and held therein via surface tension of the lubricant against the internal surfaces of the lubrication channel. The lubricant channel containing the lubricant provides a ready supply of fresh lubricant to prevent stiction from occurring between interacting components of the micromechanical device disposed within the processing region.

  • Method and apparatus for providing carrier synchronization in digital broadcast and interactive systems
    Publication number: 20080181344
    Abstract: An approach is provided for supporting carrier synchronization in a digital broadcast and interactive system. A carrier synchronization module receives one or more signals representing a frame that includes one or more overhead fields (e.g., preamble and optional pilot blocks and one or multiple segments separated by pilot blocks). The module estimates carrier frequency and phase on a segment by segment basis and tracks frequency between segments. Carrier phase of the signal is estimated based upon the overhead field. Estimates carrier phase of random data field are determined based upon the estimated phase values from the overhead fields, and upon both the past and future data signals. Further, the frequency of the signal is estimated based upon the overhead fields and/or the random data field. The above arrangement is particularly suited to a digital satellite broadcast and interactive system.
