| 20090231859 | Brightness Enhancement Component - A brightness enhancement component includes a substrate and a plurality of prism elements. The prism elements are disposed on the substrate, and each element prism has a relatively high crest and at least one relatively low crest. A crest line of the relatively low crest is equal to or shorter than a crest line of the relatively high crest in length. All of the relatively high crests have their crest lines in parallel with one another, or all of the relatively high and relatively low crests have their crest lines in parallel with one another. | 09-17-2009 |

| 20120091816 | POWER SYSTEMS WITH MULTIPLE POWER SOURCES - In one embodiment, a power system includes a first power source having a first voltage, a second power source having a second voltage, and a controller. The controller is coupled to the first power source and the second power source. The controller compares the first voltage with the second voltage, controls the first power source to charge the second power source via a first switch and a second switch in a charging mode when the first voltage is greater than said second voltage, and controls the second power source to power a load such as a light-emitting diode (LED) light source via the second switch and a third switch in a load-powering mode when the second voltage is greater than the first voltage. | 04-19-2012 |

| 20090263008 | Method For Recognizing Dice Dots - A method recognizing dice dots comprises the steps: projecting at least one dice with a plurality of different angle light sources; capturing a plurality of images of the dice according to the projecting times of the light sources on the dice; and recognizing dice dots based on the images through calculation methods. When recognized results obtained through the calculation methods are judged same by the recognizing module the dice dots are confirmed and accepted. If the recognized results done through the calculation methods are different, the dice is rolled anew. | 10-22-2009 |
| 20090264186 | Apparatus For Recognizing Dice Dots - An apparatus for recognizing dice dots includes a dice cup to hold at least one dice, and a light source module and a capturing module located in the dice cup. The light source module generates a plurality of light sources to project to the dice. The capturing module captures images of the dice a number of times according to the light sources projection times to generate a plurality of image information. The image information are sent to a recognizing module which stores a plurality of calculation methods to recognize dice dots according to the image information. When recognized results obtained through the calculation methods are judged same by the recognizing module the dice dots are confirmed and accepted. If the recognized results done through the calculation methods are different, the dice is rolled anew. | 10-22-2009 |

| 20090146163 | HIGH BRIGHTNESS LIGHT EMITTING DIODE STRUCTURE - The present invention discloses a high brightness LED structure, wherein a highly-doped n-type AlInP island structure is formed on a portion of the surface of an AlGaInP semiconductor stack structure and functions as a current barrier structure. The island structure is covered by a p-type window layer and positioned below a p-type ohmic electrode. The island structure can make more input current flow to the AlGaInP semiconductor stack structure not shielded by the light-emitting side electrode and thus can optimize the current distribution and promote the light-emitting efficiency. | 06-11-2009 |
