  • Patent number: 10240913
    Abstract: The invention makes it possible to measure an object with a three dimensional shape that is made of various materials with a high degree of precision and at high-speed, without requiring a vast amount advance of preparation. A measuring unit detects internal scattering light measuring areas in a captured image, and obtains profiles of internal scattering light components in the areas. An estimating unit estimates the internal scattering light components in three-dimensional coordinate measuring areas based on the profiles of the internal scattering light components in the internal scattering light measuring areas. A reducing unit reduces the internal scattering light components in the three-dimensional coordinate measuring areas to generate a direct-reflected light component image. Then, a calculating unit calculates three-dimensional coordinates on measuring lines based on the direct-reflected light component image.

  • Publication number: 20180336691
    Abstract: Whether to correct unevenness of brightness of a first image of an object onto which pattern light for three-dimensional shape measurement is projected is determined based on the first image or a second image of the object onto which the pattern light is not projected. If correction is performed, the three-dimensional shape of the object is measured using a corrected image obtained by correcting the unevenness of the brightness of the first image based on the second image; otherwise, the three-dimensional shape of the object is measured using the first image.

  • Publication number: 20170280692
    Abstract: An object of the present invention is to produce a mammalian organ having a complicated cellular composition composed of multiple kinds of cells, such as kidney, pancreas, thymus and hair, in the living body of a non-human animal. The inventors of the present invention applied the chimeric animal assay described above, to a novel solid organ production method. More specifically, the inventors has shown that a model mouse which is deficient of kidney, pancreas, thymus or hair due to the dysfunction of the metanephric mesenchyme that is differentiated into most of an adult kidney, is rescued by blastocyst complementation by the chimeric animal assay, and whereby a kidney, a pancreas, thymus or hair can be newly produced.

  • Patent number: 9714826
    Abstract: A shape of an object is measured using a plurality of space encoding patterns each of which includes a light portion and a dark portion. A first and second pattern sets are obtained. The first set comprises patterns each of which has the light portion of each space encoding pattern masked by a pattern mask. The second set comprises patterns each of which has the light portion of each of the space encoding pattern masked by a mask with varying the mask pattern. Captured images of an object on which the patterns of the first and second sets are sequentially projected are inputted. A correspondence between projection coordinates of the projected pattern and image coordinates of a captured image for the projected pattern is detected. A shape of the object is derived based on correspondences.

  • Publication number: 20170127363
    Abstract: A radio equipment controller (REC) includes a transmission serializer/deserializer (SERDES), a reception SERDES, and an adjustment unit. The adjustment unit adjusts a transmission timing of a downlink frame to be transmitted from the transmission SERDES in the REC so that the transmission timing of the downlink frame from an antenna of radio equipment (RE) becomes a predetermined timing after synchronization of a downlink and an uplink is established. The RE includes a transmission SERDES, a reception SERDES, and a control unit. The control unit causes the transmission SERDES in the RE to start transmitting an uplink frame after the synchronization of the downlink is established with the REC. The control unit also causes the transmission SERDES in the RE to maintain a transmission timing of the uplink frame, even if a synchronization loss of the downlink is detected due to adjustment of the transmission timing of the downlink frame.

  • Patent number: 9557167
    Abstract: A first image of a space onto which a first light pattern formed from bright and dark portions and a coordinate-detection pattern projected onto each region of the space divided by the first pattern have been projected is acquired. A second image is acquired of the space onto which a second light pattern having a boundary position between bright and dark portions that is different from that of the first pattern, and a coordinate-detection pattern projected onto each region of the space divided by the second pattern have been projected. One of the first image and the second image is selected to perform three-dimensional shape measurement of an object included in the space based on the selection image.

  • Publication number: 20160324130
    Abstract: It is revealed that an organ such as pancreas can be regenerated by utilizing a fact that the deficiency of an organ is complemented by injecting an induced pluripotent stem cell (iPS cell) into a developed blastocyst in a blastocyst complementation method. Thus, the present invention has solved the above-described object. This provides a method for producing a target organ, using an iPS cell, in a living body of a non-human mammal having an abnormality associated with a lack of development of the target organ in a development stage, the target organ produced being derived from a different individual mammal that is an individual different from the non-human mammal.
