Abstract: In one general aspect, a method is described. The method includes generating a positional relationship between one or more support structures having at least one motion capture mark and at least one virtual structure corresponding to geometry of an object to be tracked and positioning the support structures on the object to be tracked. The support structures has sufficient rigidity that, if there are multiple marks, the marks on each support structure maintain substantially fixed distances from each other in response to movement by the object. The method also includes determining an effective quantity of ray traces between one or more camera views and one or more marks on the support structures, and estimating an orientation of the virtual structure by aligning the determined effective quantity of ray traces with a known configuration of marks on the support structures.

Abstract: A method for associating a portion of a stereoscopic image with a perceived depth is described. The method includes determining offset values that each indicate a displacement between image data in a first image of a stereoscopic pair and corresponding image data in a second image of the stereoscopic pair. The displacement affects a perceived depth of a point represented by the image data and the corresponding image data. The method also includes identifying image data in the second image that is not associated with a valid offset value, generating a supplementary offset value using valid offset values associated with image data substantially near the image data in the second image, and associating the image data in the second image with the supplementary offset value.

Abstract: A method and circuit thereof for performing setup and hold (SUAH) testing on integrated circuits including, but not limited to SRAM, utilizing a relatively low number of test vectors, obviating the conventional requirement of writing to and reading back from each and every memory address. In one embodiment, a first test data signal of all zeros (0) is inputted to the input stage of the SRAM under test, and a subsequent second data signal of all ones (1) follows. In one embodiment, XOR/XNOR gates detect differences in data signals between the inputs and outputs of input stage latches/registers after clocking. In one embodiment, detected differences are combined into an error signal in combinational logic. In one embodiment, error signals are exported serially to a test system by a scan chain. Alternatively, in another embodiment, error signals are exported in parallel via individual output drivers.

Abstract: An integrated circuit includes a test circuit that may be configured to generate a test signal having a predetermined pulse width in response to a control input. The test signal may track process corners of the integrated circuit and may be used to predict a failure of the integrated circuit.

A method of performing a low stress test mode may include applying an initial voltage in an amount sufficient to perform a device burn-in to a first device and a second device. Voltage at the second device is reduced, wherein voltage is reduced at the second device while voltage at the first device is at an amount sufficient to perform device burn-in.

Abstract: Feature correspondence between images using an image pyramid is disclosed. In one embodiment, a fundamental matrix between a first and a second image is generated from the image pyramid. The image pyramid is first generated, and has a predetermined number of fineness levels, from a coarsest to a finest level. Each of the images has significant features at each pyramid level. A plurality of hypotheses, or particles, is generated for the fundamental matrix at the coarsest level, based on matching significant features of the images at the coarsest level. In an iterative procession through the levels of the image pyramid, starting at a present level initially set to the coarsest level and then subsequently advanced by one fineness level upon each iteration, an importance sampling function is first formulated from the hypotheses. The plurality of hypotheses is then generated at the next pyramid level based on the function, and on the significant features of the images at this next level.

Abstract: The present invention is directed to a buffer improvement for higher speed operation. A buffer may include at least two buffer stages, which may include a first buffer stage and a second buffer stage. A voltage conversion circuit is disposed between the first buffer stage and the second buffer stage. The voltage conversion circuit is suitable for acting as a delay between the first buffer stage and the second buffer stage. Additionally, the first buffer stage may be driven directly, thereby increasing buffer speed.

Abstract: A rotating machine such as a submersible pump which comprises a casing (1) and a rotor (2) which is rotatable relative to the casing (1). The casing defines an aperature adjacent to which the rotor is positioned such that an annular gap is formed around the aperture between a first surface defined by the rotor (2) and a second surface (9) defined by the casing (1). One or both of the first and second surfaces is provided with a surface structure which is operative to prevent the accumulation of material within the gap. The irregular surface may be defined by for example a screw thread.
