Abstract: A method for computer-assisted hair coloring guidance includes the step of determining a hair section area, in which hair is depicted, in a digital image of a person where a plurality of hairs are visible. Determining this hair section area can include the step of determining an image color information frequency distribution which can correspond to a frequency distribution of at least one item of color information for a plurality of image points in the digital image; as well as the step of comparing this frequency distribution of image color information to hair color statistics, where the hair color statistics may include, for each of a plurality of hair colors, at least one frequency distribution of at least one item of hair color information.

Abstract: The present application relates to an automatic door assembly with a door arm comprising at least two rectilinearly movable sections.

Abstract: To accommodate differential thermal growth of a component and its support, a pair of temperature responsive mounts are provided. Each mount comprises a rigid, bowed beam having lugs at each end affixed to the component and an intermediate lug affixed to the case. Thermal expansions of the beams and the component load the beams in compression, causing flexures thereof in directions to produce motions of the third lugs that track the thermal growth of the support.

Abstract: An improved disk clutch structure in which a hydraulic piston provides the force to cause frictional contact between clutch plates. The invention resides in the use of a drain conduit and pressure responsive drain valve in combination with a vent conduit and a pressure responsive vent valve to remove hydraulic fluid from the hydraulic cylinder on inactivation of the clutch with the location of conduits being such that removal of the fluid from the cylinder is assisted by centrifugal forces created by moving clutch parts and such that only the hydraulic cylinder is evacuated.
