Abstract: The techniques disclosed herein use a compass, MEMS accelerometer, GPS module, and MEMS gyrometer to infer a frame of reference for a hand-held device. This can provide a true Frenet frame, i.e., X- and Y-vectors for the display, and also a Z-vector that points perpendicularly to the display. In fact, with various inertial clues from accelerometer, gyrometer, and other instruments that report their states in real time, it is possible to track the Frenet frame of the device in real time to provide a continuous 3D frame-of-reference. Once this continuous frame of reference is known, the position of a user's eyes may either be inferred or calculated directly by using a device's front-facing camera. With the position of the user's eyes and a continuous 3D frame-of-reference for the display, more realistic virtual 3D depictions of the objects on the device's display may be created and interacted with by the user.

Abstract: Methods and apparatuses for locating an embedded color chart in an image are described. In one exemplary method, an image that includes an embedded color chart is located without the intervention of the user. The embedded color chart is verified and used to create a color profile of the image. Furthermore, the orientation angle of the color chart is determined and the image orientation is fixed based on this angle.

Abstract: A bucket is capable of holding a sample container in a rotary centrifuge. The bucket has a receptacle to receive the sample container and a trunnion joined to the bucket. The trunnion has a plurality of cutouts that each define a flexible span that is sufficiently thin to flex under application of a centrifugal force generated by the rotary centrifuge, and pivot pins to that allows the bucket to pivot under the application of the centrifugal force. The receptacle has an open end having an internal surface with a tapering groove and a self-seating cap having pegs sized to fit in the tapering groove.

Abstract: Systems, methods, and computer readable media for performing color correction operations to address memory color artifacts in a manner suited for real-time operations. In general, techniques are disclosed for correcting memory color rendering artifacts in an image without performing color space conversions. In one implementations, hue-saturation-value (HSV) image correction values may be expressed solely in terms of an image's base red-green-blue (RGB) color space values. Once expressed in this manner, color correction may be applied to the image directly—without the need to convert the image's color space into and out of a working color space (e.g., an HSV color space). As no color space conversions are necessary, the disclosed techniques are well-suited to real-time operations.

Abstract: Data indicating a problem in a network is derived by collecting reformatting requests from devices in the network. The reformatting requests are generated by the devices in response to problems the devices experience in communicating using the network. The reformatting requests are correlated to determine a pattern in the reformatting requests over a period of time, and data indicating a problem in the network is derived based on the pattern.

Abstract: GPU fragment programs can be used to render images in a computer system. These fragment programs are generated from render trees, which specify one or more filters or functions to be applied to an input image to render an output image. It is not uncommon for successive frames to require application of substantially the same filters. Therefore, rather than regenerate and recompile new fragment programs for successive corresponding render trees, the render trees are substantially uniquely identified and cached. Thus, when a render tree is received, it can be identified, and this identifier (such as a hash) can be used to determine whether a corresponding fragment program has already been generated, compiled and cached. If so, the corresponding cached fragment program is retrieved and executed. If not, a fragment program for the newly received render tree is generated and cached.

Abstract translation: GPU片段程序可用于在计算机系统中呈现图像。 这些片段程序是从渲染树生成的，它们指定要应用于输入图像以呈现输出图像的一个或多个过滤器或函数。 连续的帧要求使用基本上相同的滤波器并不罕见。 因此，渲染树不是重新生成并重新编译连续相应渲染树的新片段程序，而是基本上唯一地标识和缓存。 因此，当接收到渲染树时，可以识别它，并且可以使用该标识符（例如散列）来确定是否已经生成，编译和高速缓存对应的片段程序。 如果是，则检索并执行相应的缓存片段程序。 如果没有，则生成并缓存新接收的渲染树的片段程序。
