  • Patent number: 8550662
    Abstract: The light source module provided by the present invention includes a base plate and a plurality of LED lights arranged on the base plate. These LED lights are distributed on the base plate in such manner that all of the light centers of the LED lights define together a triangle shape. An angle of 50-70 degree is defined between a LED light and two adjacent LED lights. The present invention has many advantages. For example, because the LED lights are distributed in a triangle arrangement, the dark regions are reduced effectively. Moreover, alternative dark and bright strips are eliminated. In addition, the base plates can be assembled quickly by means of the connective members.

  • Patent number: 8146032
    Abstract: One embodiment of the present invention provides a system that performs an RLC extraction for a three-dimensional integrated circuit (3D-IC) die. During operation, the system receives a 3D-IC die description. The system then transforms the 3D-IC die description into a set of 2D-IC die descriptions, wherein the transform maintains equivalency between the set of 2D-IC die descriptions and the 3D-IC die description. Next, for each 2D-IC die description in the set of 2D-IC die descriptions, the system performs an electrical property extraction using a 2D-IC extraction tool to obtain a 2D-IC RLC netlist file. The system then combines the set of 2D-IC RLC netlist files for the set of 2D-IC die descriptions to form an RLC netlist file for the 3D-IC die description.
