  • Patent number: 7265753
    Abstract: A method of rendering computer graphics is disclosed comprising the steps of: processing a set of light particles in a scene to be rendered; selecting a view of the scene, where the view comprises at least one surface, the surface comprising a plurality of pixels; selecting a pixel to render in the view; determining whether an illumination mesh already exists for a surface comprised of the selected pixel; computing an illumination mesh for the surface, when the illumination mesh does not already exist; and rendering the pixel with the illumination mesh.

  • Patent number: 7221171
    Abstract: An enhanced membrane interface probe (MIP) is disclosed including: a modular membrane interface probe (MIP) sensor constructed from a plurality of modular components allowing field serviceable replacement of any malfunctioning components of the plurality of modular components. The modular MIP can include: an external barrel having a cavity; or (or throughout means and/or, i.e., a logical or operation) an inner core barrel assembly field-insertable into the cavity having a heater cavity, where the heater cavity is adapted to receive a field-insertable removable cartridge heating element. The modular MIP can include a removable conductivity nose assembly, a field-insertable removable cartridge heating element, or a waterproof electrical connector and/or an o-ring seal.

  • Patent number: 7215867
    Abstract: In order to keep the load on the cables in a cable storage device as light as possible during the process of storing, and furthermore in order to keep the release of the cables as simple as possible, a cable storage device is provided in which at least on one side of the storage device a shoulder of a block is provided, which during storage is pushed down by the cable gripper, and as a result of this during storage the cable or cable end is practically not exposed to any transverse or longitudinal load. In this arrangement the block with the shoulder or shoulders is pushed upward by a spring and in this way ensures reliable clamping action in the storage device.

  • Patent number: 7114449
    Abstract: A method for producing a large-caliber, high-explosive projectile (1, 1?), and a projectile formed according the method, having a projectile casing (2, 2?) that surrounds a chamber (6, 6?) filled with an explosive charge (9, 9?), and that has a mouth (5, 5?) at its tip that can be sealed, and through which the explosive charge (9, 9?) is inserted into the chamber (6, 6?) of the high-explosive projectile (1, 1?). The explosive charge (9, 9?) is disposed in a plastic casing (8), comprised of an elastic material, inside the chamber of the high-explosive projectile (1, 1?). Additional tensioning means (11, 11?, 17, 17?) are provided to compensate for the varying volume of the explosive charge (9, 9?) relative to the projectile casing (2, 2?) if the temperature fluctuates dramatically and maintain the explosive charge (9, 9?) under a pre-stress, particularly when using a plastic bound explosive charge (9, 9?).

  • Patent number: 6895052
    Abstract: Herein disclosed a bit stream separating apparatus for inputting and transcoding an original MPEG-2 bit stream, and separating the transcoded MPEG-2 bit stream to generate a transcoded MPEG-2 bit stream and a differential bit stream, which is a differential bit stream between the original MPEG-2 bit stream and the transcoded MPEG-2 bit stream, and a bit stream merging apparatus for inputting and merging the transcoded MPEG-2 bit stream and the differential bit stream to reconstruct the original MPEG-2 bit stream. The bit stream separating apparatus makes it possible for the bit stream merging apparatus to reconstruct the original, high quality, MPEG-2 bit stream from the transcoded MPEG-2 bit stream already received and the differential bit stream, thereby eliminating the effort and time to send the original MPEG-2 bit stream again.

  • Patent number: 6608420
    Abstract: A stator includes an integrated yoke with upper and lower insulators provided on upper and lower ends thereof and stator coils directly wound around the insulators and the yoke. Wherein the yoke has an outer annular member and an inner annular member integrally formed therewith. The upper and lower insulators respectively have two outer rings and two inner rings integrally formed therewith corresponding to the outer and inner annular members of the yoke. Whereby the structure of the stator is simple and manufacturing of the stator is efficient.
