  • Publication number: 20220176947
    Abstract: Methods and apparatus for matching portions of images are described as well as using depth information generated from the matching results. In various embodiments, lower portions of images of a scene area, which are more likely to include objects closer to a vehicle on which cameras are mounted, than are portions of images corresponding to an upper portion of the scene area, are processed and used for depth determination. In this way, depths to objects, which are likely to be closer to the vehicle than objects in the upper portion of the scene area, are determined first and used to control a vehicle reducing the risk of collision as compared to systems where the depth determination of an entire scene is completed before depth information is used for control purposes with the order of processing being such that nearer objects are likely to be detected prior to more distant objects.

  • Publication number: 20210333194
    Abstract: A microfluidic chip configuration wherein injection occurs in an upwards vertical direction, and fluid vessels are located below the chip in order to minimize particle settling before and at the analysis portion of the chip's channels. The input and fluid flow up through the bottom of the chip, in one aspect using a manifold, which avoids orthogonal re-orientation of fluid dynamics. The contents of the vial are located below the chip and pumped upwards and vertically directly into the first channel of the chip. A long channel extends from the bottom of the chip to near the top of the chip. Then the channel takes a short horizontal turn that nearly negates any influence of cell settling due to gravity and zero flow velocity at the walls. The fluid is pumped up to a horizontal analysis portion that is the highest channel/fluidic point in the chip and thus close to the top of the chip, which results in clearer imaging.

  • Patent number: 11107965
    Abstract: A quantum computing device is fabricated by forming, on a superconductor layer, a first resist pattern defining a device region and a sensing region within the device region. The superconductor layer within the sensing region is removed, exposing a region of an underlying semiconductor layer outside the device region. The exposed region of the semiconductor layer is implanted, forming an isolation region surrounding the device region. Using an etching process subsequent to the implanting, the sensing region and a portion of the device region of the superconductor layer adjacent to the isolation region are exposed. By depositing a first metal layer within the sensing region, a tunnel junction gate is formed. A sensing region gate is formed by coupling the semiconductor layer with a second metal layer. A nanorod contact using the second metal within the portion of the device region outside the sensing region is formed.
