  • Patent number: 7858912
    Abstract: An optical sensor has at least one pixel that generates an output voltage that changes at a rate dependent on the light intensity incident on the pixel. The time for the pixel output voltage to change from a first predefined level to a second predefined level is measured, so as to produce an output indicative of the incident light intensity.

  • Publication number: 20100033964
    Abstract: The present invention is an alternative lighting technology to form light emitting diode (LED) light tube. The tubular or circular LED tube is formed by transparent plastic and a metal heat sink that includes LEDs soldered onto a metal core printed circuit board with a special arrangement to achieve greater brightness than an equal distance arrangement. All LEDs are directly inserted into the metal core printed circuit board with a unique insulation coating to allow the LED anode and cathode to be inserted into the metal core printed circuit board and soldered on the opposite side of the metal core printed circuit board. It can connect one or more control units to control intensity.

  • Patent number: 7290594
    Abstract: An intercooler configured for attachment to an automobile is disclosed. One embodiment of the invention includes an intercooler body having an inlet manifold on one end and an outlet manifold on the other end, and a decorative top plate on the top of the intercooler attached to the manifolds. The decorative top plate has two holes in it which are both keyed to resist rotation of an insert, a hollow bolt having a stepped formation under the bolt head such that the stepped formation is able to key in the hole cut in the plate, the bolt is inserted through the top of the plate and secured by a nut secured underneath it so that the head of the bolt lies flush against the plate and the stepped formation keys against the hole to prevent rotation. In addition, the bolt is hollow having a threaded passage passing through it to receive another bolt to secure the intercooler to a bracket in the automobile.

  • Patent number: 7285942
    Abstract: A low-dropout regulator with a single-transistor-control providing improved transient response and stability is disclosed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot, and hence improves transient response. Since the single-control transistor reduces the output resistance of the regulator, the output pole is pushed to a sufficiently high frequency without affecting stability. Therefore, the limited choice of combinations of the output capacitance and its equivalent-series-resistance is substantially relaxed.

  • Patent number: 7120775
    Abstract: A method for an allocation of stacked registers for Intel's ItaniumĀ® processor includes a three step process. Step I determines an intra-procedural stacked register usage by a program having a plurality of procedures. In step II, the disclosed method performs an inter-procedural analysis to assign quota of stacked register usage to every procedure. In step III, each procedure is allocated stacked register usage based on the quota assignments of step II.

  • Patent number: 7120906
    Abstract: A method and computer program product, within an optimizing compiler, for precise feedback data generation and updating. The method and computer program uses instrumentation and annotation of frequency values to allow feedback data to stay current during the multiple optimizations that the program code undergoes during compilation. Global propagation of known precise feedback values are used to replace approximate and unavailable values, and global verification of feedback data after optimization to detect discrepancies is employed. The method and computer program also provides improved instrumentation to anticipate cloning when code is cloned during ceratin compiler optimizations and handles inlined procedures. The result is compiled executables with improved SPECint benchmarks.
