  • Patent number: 7714803
    Abstract: This invention describes procedures for writing data to a spatial light modulator (SLM) to achieve the purpose of “sub-frame method”, i.e. increasing effective frame rate of the SLM, without the need of additional color switching means or modulation at illumination source. The purpose is to improve the resolution of V3D displays based on projectors. The method divides the pixels of the SLM into a number of groups and defines each group as a sub-panel. Frames of image data are then written in sequence to each of the sub-panels in a fixed order. An image frame written to a sub-panel is called a “sub-frame” when displayed on the sub-panel. The method then displays one sub-frame on one sub-panel at a time, with the rest sub-panels displaying blank (black). If the SLM has no memory buffer and image is displayed when it is written, then all data on the SLM must be erased after a sub-panel is being displayed and before the next sub-panel is written.

    Abstract: A razor blade unit for safety razor has optimized shape and dimensions for body shaving, especially the regions of the axillae. The blade unit has an elongate blade with a rectilinear sharpened edge, and a skin contacting surface at which the length is 1 to 4 times the width and not greater than 60 mm, preferably 40 to 45 mm. The skin contacting surface has a footprint area of at least 450 mm2, preferably 600 to 750 mm2, and a circularity which is not less than the lower of (i) 65%, and (ii) the circularity of a rectangle with the same length and width as the skin contacting surface and with corner radii of 30% of the width. In a plane perpendicular to the blade edge the skin contacting surface is convex and shaped to make at least three point contact with an imaginary circumscribing circle with a radius of 15 to 70 mm, preferably 25 mm. Guard cap surfaces in front of and behind the blade edge each have a skin contact area of at least 140 mm2, and their combined area is preferably at least 400 mm2, e.g.

  • Patent number: 6473970
    Abstract: A blade cartridge including one or more blades fixed between a platform member and a cap member. The blades have apertures that allow lubricants removed from a surface of a shaver by the cutting edge of the blade to be transported through the blade and supplied to the cutting edge of the adjacent blade or to a skin engaging surface of the cap member, whichever the case may be. The apertures in the blades define flow paths that allow lubricants to reach successive cutting edges or skin engaging surfaces, thereby reducing irritation to the shaver. The blades are spaced apart by spacers that are constructed with passages that allow the free flow of lubricant through adjacent flow paths. The cap member includes passages that allow the free flow of lubricating agents through the flow paths to the skin engaging surface of the cap member.

  • Patent number: 6430818
    Abstract: A blade cartridge including a platform member having a blade seat, and a guard member located forward of and parallel to the blade seat so as to form a longitudinal slot between the blade seat and the guard member. A first blade is disposed on the blade seat such that the cutting edge of the blade is located rearwardly of the guard member. A spacer is located on the upper surface of the first blade. The spacer includes an upper surface having a plurality of protruding members extending therefrom and extending through apertures on a second blade such that the second blade is disposed on the upper surface of the spacer. The first blade has apertures that allow debris to flow between the first and second blades and downward through the aperture in the first blade and out through the platform member. A third blade is disposed on an upper surface of the protruding members of the spacer, thereby forming a gap defined by the second and third blades.

  • Patent number: 6378211
    Abstract: A blade cartridge including one or more blades fixed between a platform member and a cap member. The present invention provides a novel blade cartridge including one or more protruding members, or guard ribs, positioned proximate the skin engaging edges of the blades such that a portion of the blade adjacent the guard ribs has a negative exposure. The guard rib preferably has an arcuate contact surface and is narrow in thickness in a direction along the skin engaging edge. Preferably a plurality of guard ribs are evenly positioned along the blade cartridge. In addition to the guard ribs on the platform member, the present invention further includes protruding members, or guard ribs, on the cap member. The guard ribs on the platform member are preferably aligned with and substantially continuous with the guard ribs on the cap member. In a further embodiment, the blade cartridge includes a spacer separating the first blade and a second blade.

  • Patent number: 6164290
    Abstract: In-line manual razor blade shaving devices feature an elongated frame having an elongated front cutter support portion arranged in-line with an elongated handle portion. The cutter support portion has first and second opposed sides upon which elongated razor blade structures, such as dual razor blade cartridges, are mounted. The elongated razor blade structures each feature at least one razor blade strip spaced from and arranged generally parallel to elongated front and rear guard portions. The guards define a working plane into which the razor blade edges of the razor blade structure project. The new in-line safety straight razors of the present invention may be utilized in a manner very much like the old unguarded in-line straight razor devices long used by barbers, except that front and rear guard portions help shield the exposed razor-sharp edges so as to minimize the occurrence of minor cuts, nicks and scrapes.
