  • Patent number: 9558954
    Abstract: The present invention relates to systems and methods associated with selective wet etching and textured surface planarization. The systems and methods described herein can be used to etch a component of a multi-layer stack, such as a GaN layer. In some embodiments, the multi-layer stack can include a substrate having a patterned surface and a light generating region. The substrate can be removed from the first multi-layer stack to form a second multi-layer stack. In some embodiments, the pattern on the surface of the substrate can leave behind a pattern on a surface of the second multi-layer stack. Accordingly, in some cases, the surface of the second multi-layer stack can be wet etched, for example, to smoothen the surface. In some embodiments, removing the substrate can expose an N-face of a GaN layer, and the wet etch can be performed such that the N-face of the GaN layer is etched. In some embodiments, the multi-layer stack includes a light generating region and can be part of a light emitting device.

    Abstract: A rendering method executed by a graphics processing unit includes: loading a vertex shading command from a first command queue to a shader module; executing the vertex shading command for computing the varying of the vertices to perform a vertex shading operation by taking the vertices as first input data; storing first tessellation stage commands into a second command queue; loading the first tessellation stage commands to the shader module; and executing the first tessellation commands for computing first tessellation stage outputs to perform a first tessellation stage of the one or more tessellation stages by taking the varying of the vertices as second input data. The vertex shading command is stored into the first command queue by a first processing unit. The varying of the vertices and the first tessellation stage outputs are stored in a cache of the graphics processing unit.

  • Publication number: 20160299503
    Abstract: An example robot includes a body that is movable relative to a surface, a bumper mounted on the body to enable movement of the bumper relative to the body, a sensor to produce a signal in response to the movement of the bumper relative to the body caused by contact between the bumper and the surface, and a controller to control movement of the body to cause the body to track the surface based on a value. The bumper is movable between an uncompressed position relative to the body and a compressed position relative to the body. The signal varies linearly with the movement of the bumper relative to the body. The value is based on the signal and indicates that the bumper in a partially compressed position has a compression range between the uncompressed position and the compressed position.
