Patent number: 8886445Abstract: The invention is a system and method of compressing a DTM to be used in an Auto-GCAS system using a semi-regular geometric compression algorithm. In general, the invention operates by first selecting the boundaries of the three dimensional map to be compressed and dividing the three dimensional map data into regular areas. Next, a type of free-edged, flat geometric surface is selected which will be used to approximate terrain data of the three dimensional map data.

Patent number: 8749576Abstract: A rasterizer stage configured to implement multiple interpolators for graphics pipeline. The rasterizer stage includes a plurality of simultaneously operable low precision interpolators for computing a first set of pixel parameters for pixels of a geometric primitive and a plurality of simultaneously operable high precision interpolators for computing a second set of pixel parameters for pixels of the geometric primitive. The rasterizer stage also includes an output mechanism coupled to the interpolators for routing computed pixel parameters into a memory array. Parameters may be programmably assigned to the interpolators and the results thereof may be programmably assigned to portions of a pixel packet.Type: GrantFiled: July 6, 2006Date of Patent: June 10, 2014Assignee: Nvidia CorporationInventors: Edward A. Hutchins, Brian K. Angell

Patent number: 8723881Abstract: A method and an electronic device for tactile feedback are provided. An original image is input and converted to a binary image which includes a first grayscale value and a second grayscale value. The original image is converted to a grayscale image at least including a third grayscale value between the first grayscale value and the second grayscale value. An index map is generated according to the binary image and the grayscale image. The index map includes a plurality of index values indicative of different strengths for tactile feedback. A touch input on a touch panel is detected when the original image is displayed on a display panel. In response to the detected touch input, a tactile activation unit is driven to generate tactile feedback according to the index map.Type: GrantFiled: February 8, 2012Date of Patent: May 13, 2014Assignee: Quanta Computer Inc.Inventors: Yu-Liang Shih, Jung-Wen Chang
