  • Patent number: 11150345
    Abstract: First and second types of object detectors, a sensing device, and a mobile apparatus. The first and second types of object detectors include a light source configured to emit light, photoreceptor configured to receive the light reflected by an object, and a binarizing circuit configured to binarize a signal sent from the photoreceptor at a threshold Vth. In the first and second types of object detectors, object detection processes are performed in a same direction until a high-level signal is output M times from the signal binarized by the binarizing circuit. In the first type of object detector, a value of the M is determined based on an incidence of shot noise where peak intensity exceeds the threshold Vth in the photoreceptor. In the second type of object detector, a threshold Vth is set based on a value of the M.

  • Publication number: 20200410727
    Abstract: An X-ray tomosynthesis apparatus accurately extracts a region of a small high absorber in a subject on 2D measurement projection data. When pieces of the 2D measurement projection data for each of a plurality of projection angles are arranged in a projection angle direction, the 2D measurement projection data is shifted in a 2D plane so that part or all of a range of a high absorber region included in the 2D measurement projection data overlaps at least a range of the high absorber region included in 2D measurement projection data at an adjacent projection angle in an in-plane direction of the 2D plane. The 2D measurement projection data for each of the plurality of projection angles after shifting is arranged in the projection angle direction to obtain 3D measurement projection data, and a 3D region is obtained from a first start point by a region expansion process.

  • Patent number: 10777570
    Abstract: An annular dielectric spacer can be formed at a level of a joint-level dielectric material layer between vertically neighboring pairs of alternating stacks of insulating layers and spacer material layers. After formation of a memory opening through multiple alternating stacks and formation of a memory film therein, an anisotropic etch can be performed to remove a horizontal bottom portion of the memory film. The annular dielectric spacer can protect underlying portions of the memory film during the anisotropic etch.

  • Publication number: 20190299032
    Abstract: An oil-in water emulsion cosmetic composition has a good feeling in use and excellent dispersion stability, and does not cause patchiness upon drying. A hydrophobized powder is dispersed in an oil phase and processed with a wet type disperser to obtain a dispersed solution. A water phase is added thereto and processed with a homomixer, to obtain an oil-in water emulsion composition having excellent usability. The powder is easily dispersed upon application to skin. The dispersion stability of the powder is further improved, and the precipitation and creaming of the emulsion particle can be eliminated by blending a thickener having salt tolerance. A sticky feeling is eliminated by using succinoglycan as a thickener, and patchiness is eliminated by plasticizing said succinoglycan.

  • Patent number: 10429508
    Abstract: A distance measuring device includes a first measurer, a second distance measurer, and circuitry. The first distance measurer measures a distance to a target object; and outputs first distance information indicating a measured distance when the distance measurement is performed under a condition that satisfies a distance measurement condition, but outputs the first distance information indicating a predetermined value when the distance measurement is performed under a condition that does not satisfy the distance measurement condition. The second distance measurer measures a distance to the target object and outputs second distance information indicating the measured distance. When the first distance information indicates the predetermined value and the second distance information satisfies a predetermined condition, the circuitry makes alteration such that the distance measurement condition is relaxed.
