Title: Graphics processing
Inventor: NYSTAD JOERN
IPC: G06T15/80
Filed: 2012-03-02
Abstract: PROBLEM TO BE SOLVED: To improve operation of graphics processors including vertex shading stages.SOLUTION: A graphics processor includes a vertex shader that processes input attribute values from a vertex buffer to generate output vertex shaded attribute values to be used by a rasterizer/fragment shader of the graphics processor when processing an image. The system recognizes when a vertex shader output attribute value to be generated from the vertex shader input attribute value by the vertex shader will be a copy of the vertex shader input attribute value. In this event, the vertex shader 20 does not generate the copy vertex shader output attribute value, but the rasterizer/fragment shader 22 instead processes the corresponding vertex shader input attribute value in place of the original vertex shader output attribute value of the vertex shader 20.

Title: Adaptive switch mode led system
Inventor: JIN XUECHENG
IPC: H05B37/02
Filed: 2012-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a cost-effective solution for maintaining precise control over the relative brightness of different LED channels while still allowing for current variations between LED channels.SOLUTION: The present invention relates to a system that provides an intelligent approach to driving multiple strings of LEDs. A processing device determines an optimal current level for each LED string from a limited set of allowed currents. The processing device also determines a PWM duty cycle for driving the LEDs in each LED string to provide precise brightness control over the LED string. The settings for the current level and duty cycle are transmitted to an LED driver for regulating the current and on-off times of the LED strings. Beneficially, the system reduces the size of the LED driver while leveraging existing resources available in the processing device to operate the LEDs in a power-efficient manner.
