  • Patent number: 11762071
    Abstract: A method for multi-sensor calibration includes imaging a calibration target with a first sensor using a first modality to obtain a first set of data and a second sensor using a second modality that is different from the first modality to obtain a second set of data. A border of the calibration target is identified based on the first set of data. A first centroid location of the calibration target is identified based on the border of the calibration target. A border of a pattern disposed on the calibration target is identified based on the second set of data. A second centroid location of the calibration target is identified based on the border of the pattern. Calibration data for the first sensor and the second sensor is generated based on the first centroid location and the second centroid location.

  • Patent number: 11694341
    Abstract: A CNN operates on the disparity or motion outputs of a block matching hardware module, such as a DMPAC module, to produce refined disparity or motion streams which improve operations in images having ambiguous regions. As the block matching hardware module provides most of the processing, the CNN can be small and thus able to operate in real time, in contrast to CNNs which are performing all of the processing. In one example, the CNN operation is performed only if the block hardware module output confidence level is below a predetermined amount. The CNN can have a number of different configurations and still be sufficiently small to operate in real time on conventional platforms.

  • Publication number: 20220213463
    Abstract: The present invention relates to an Fe—S fusion protein acting as an electron transport chain, a novel carbon monoxide:formate oxidoreductase (CFOR) including the Fe—S fusion protein, novel Thermococcus strain BCF12 transformed with CFOR, and the use thereof. According to the present invention, two different enzymes may be physically linked directly to each other through the Fe—S fusion protein of the present invention, and thus electrons generated from any one enzyme may be transported directly to another enzyme through the Fe—S cluster of the Fe—S fusion protein. Accordingly, a reaction that produces a target substance with high efficiency by directly supplying electrons necessary for the production of the target substance is possible without leakage of electrons generated in any one enzyme. In addition, the present invention has an advantage in that the overall enzyme reaction rate and yield can be dramatically improved using a new electron transport reaction.
