Publication number: 20240144535Abstract: Systems and methods for measuring skin tone. A camera and computer may measure skin tone health of a face dataset and color quality of a single face image. The computer and camera may measure skin tone across wide sample of volunteers, express skin tone in CIELCH coordinates; and identify the range of observed lightness, chromaticity, and hue values in the population to determine a sample set. The computer and camera may be configured to match the image to a coordinate system of lightness, chromaticity, and hue in the sample set. If a match is not possible, the computer may be configured to select a coordinate closest to the measured lightness, chromaticity, and hue.Type: ApplicationFiled: October 19, 2023Publication date: May 2, 2024Applicant: The Government of the United States of America, as represented by the Secretary of Homeland SecurityInventors: Arun Vemury, Yevgeniy Sirotin, John Howard, Jerry Tipton

Patent number: 4003278Abstract: A device for cutting lengths of tubing from a longer tube utilizes an external pair of cutting dies and an internal pair of punches. An eccentric relative motion ("shimmy") of the cutting dies results in the desired cutting of the tube. The punches are inserted into the tube from the end of the tube from which the length of tubing is to be cut. A restraining arrangement prevents the punches from moving farther along the tube than is desired, while a punch positioning mechanism prevents movement of the punches toward the open end of the tube. Thus, the internal punches are accurately positioned with respect to the external cutting dies. A centering arrangement is utilized to insure coaxiality of the punches.Type: GrantFiled: March 14, 1975Date of Patent: January 18, 1977Assignee: Jackes-Evans Manufacturing CompanyInventor: John Tipton Shields
