  • Appearance inspection device, lighting device, and imaging lighting device
    Patent number: 10890537
    Abstract: An imaging lighting device of an appearance inspection device images a product T. A controller of the appearance inspection device causes an imaging control unit to obtain an image, a preprocessing unit to position the product and remove background of the product, a color space processing unit to perform color space processing for emphasizing a defect such as a flaw and a dent of the product and to create a color space processing image, and an assessment unit to make an quality assessment of the product using a learned model obtained through machine learning of quality assessment of the product using the color space processing image.
    Type: Grant
    Filed: August 1, 2017
    Date of Patent: January 12, 2021
    Assignee: SERENDIPITY CO., LTD
    Inventors: Shinichi Hanabusa, Yusuke Omori, Hayato Akuzawa

  • Biopsy apparatus
    Patent number: 8744552
    Abstract: A biopsy apparatus includes a biopsy region positional information calculator for calculating a three-dimensional position of a biopsy region, a biopsy needle moving mechanism for moving a biopsy needle along three axes and/or turning the biopsy needle obliquely to an object to be examined, a biopsy needle positional information calculator for calculating a three-dimensional position of the biopsy needle, and a traveled distance calculator for calculating a distance over which the biopsy needle moves with respect to the biopsy region based on the three-dimensional position of the biopsy needle and the three-dimensional position of the biopsy region.
