Abstract: A system includes processing hardware and a memory storing software code. When executed, the software code receives first skeleton data including a first location of each of multiple skeletal key-points from the perspective of a first camera, receives second skeleton data including a second location of each of the skeletal key-points from the perspective of a second camera, correlates first and second locations of some or all of the multiple skeletal key-points to produce correlated skeletal key-point location data for each of at least some skeletal key-points. The software code further merges the correlated skeletal key-point location data for each of those at least some skeletal key-points to provide merged location data, and generates, using the merged location data and the locations of the first, second, and third cameras, a mapping of the 3D pose of a skeleton.

Abstract: The present disclosure is related to methods and systems for calibrating a projector. The method includes displaying a plurality of calibration patterns, where the calibration patterns are displayed separately by different wavelength channel bands, e.g., red channel, blue channel, green channel. The method then includes receiving by a processing element one or more calibration images. The method then includes determining one or more displacements corresponding to a plurality of pixels in the calibration image with respect to a plurality of pixels in the calibration pattern to adjust for distortions on a per wavelength channel basis.

Abstract: A device for locking a brake pedal of a motor vehicle includes a cylinder and a piston mounted for reciprocating movement relative to each other. A spring is positioned within the cylinder so as to urge the piston away from a retracted position and towards an extended position. The external end of the piston is adapted to engage an exposed surface of a motor vehicle's brake pedal, containing an antifriction member such as a toothed tip integrally formed therewith or a separate rubber cap attached thereto. The cylinder further includes a hook member or some other mechanism adapted to engage a front surface of a motor vehicle's driver seat. The position of the hook member on the cylinder is adjustable so as to accommodate varying distances between the brake pedal and the driver seat.

Abstract: The thermostability of the 20,396 dalton Bacillus circulans xylanase was increased by site-directed mutagenesis. The thermostability was conferred by the presence of non-native disulfide bridges, and selected N-terminal mutations. The introduction of these non-native disulfide bridges was accomplished by the examination of the three-dimensional structure of the enzyme, and choosing sites where a favorable geometry for a bridge existed. The N-terminal mutations were constructed on the basis of primary sequence comparison with other family G xylanases. The mutant proteins were examined for their ability to retain enzymatic activity after heating as an indication of increased thermostability. These thermotolerant variants are useful as an alternative to chemical bleaching of Kraft pulp in a pre-bleaching step (bio-bleaching). The pre-bleaching involves temperatures higher than that normally used for these enzymes and accordingly these thermotolerant variants can be advantageously used at this step.
