  • Patent number: 8320622
    Abstract: A system and method are provided for color gradient object tracking. A tracking area is illuminated with a chromatic light source. A color value is measured, defined by at least three attributes, reflected from an object in the tracking area, and analyzed with respect to chromatic light source characteristics. A lookup table (LUT) is accessed that cross-references color values to positions in the tracking area, and in response to accessing the LUT, the object position in the tracking area is determined. The LUT is initially built by illuminating the tracking area with the light source. A test object is inserted into the tracking area in a plurality of determined positions, and the reflected color value is measured at each determined position. The color value measurements are correlated to determined positions. As a result, a color gradient can be measured between a first determined position and a second determined position.

  • Patent number: 8314015
    Abstract: A process of silicon (Si) surface modification is provided for the electrochemical synthesis of Si particles in suspension. The process begins with a Si first substrate with a surface, and forms Si particles attached to the surface. Hydrogen-terminated Si particles are created and the first substrate is immersed in a hexane/1-octene (1/1 volume ratio) solution with a catalytic amount of chloroplatinic acid (H2PtCl6). 1-octene is bonded with the hydrogen-terminated Si particles, creating modified Si particles, with octane capping ligands, attached to the substrate surface. The first substrate is then exposed to ultrasonication, separating the modified Si particles from the first substrate. After removing the first substrate, a suspension is created of modified Si particles suspended in excess hexane/1-octene.

  • Patent number: 8291421
    Abstract: A system and method are provided for determining processor usable idle time in a system employing a software instruction processor. The method establishes an idle task with a lowest processor priority for a processor executing application software instructions, and uses the processor to execute an idle task. The method ceases to execute the idle task in response to the processor executing application software instructions. The amount of periodic idle task execution is determined and stored in a tangible memory medium. For example, idle time amounts can be determined per a unit of time, i.e. a percentage per second. In one aspect, the method generates an idle task report. The report can be a periodic report expressing the duration of idle task execution per time period, or a course of execution report expressing idle task start times, idle task stop times, and durations between the corresponding start and stop times.

  • Patent number: 8284235
    Abstract: A method for modifying images for display on a three dimensional display includes receiving a first image and a corresponding second image which together represent a three dimensional image when displayed on the three dimensional display. Based upon the first and second image, the method determines whether their content is expected to cause substantial discomfort to a viewer when displayed on the three dimensional display. At least one of the first and second images are modified based at least in part on a physical value related to the pixel pitch of the display, in such a manner to reduce the expected discomfort to the viewer.
