  • Patent number: 7137098
    Abstract: A method for determining component patterns of a raw substrate map. A subset of substrate patterns is selected from a set of substrate patterns, and combined into a composite substrate map. The substrate patterns are weighted. The composite substrate map is compared to the raw substrate map, and a degree of correlation between the composite substrate map and the raw substrate map is determined. The steps are iteratively repeated until the degree of correlation is at least a desired degree, and the weighted subset of substrate patterns is output as the component patterns of the raw substrate map.

  • Patent number: 7062415
    Abstract: A method for determining outlier data points in. A subset of dataset patterns is selected from a set of mathematical dataset patterns, and the subset of dataset patterns is combined into a composite dataset. The composite dataset is compared to the dataset, and a degree of correlation between the composite dataset and the dataset is determined. Data points within the composite dataset are selectively weighted to improve the degree of correlation, and the steps described above are selectively iteratively repeated until the degree of correlation is at least a desired value. Residuals for the data points within the composite dataset are selectively determined. At least one of the weighted data points within the composite dataset that are weighted within a first specified range, and data points within the composite dataset that have a residual within a second specified range, are selectively output as outlier data points.

  • Patent number: 6591854
    Abstract: A burst disk assembly has a burst disk which is interposed within the high pressure relief vent of a superconducting magnet. The burst disk is a composite design constructed of a solid carbon graphite center surrounded by an integrally formed stainless steel ring. A captured burst disk flange insures proper placement and seating of the burst disk during replacement and supports the burst disk so as to prevent it from falling or dropping out of the assembly during replacement of the ruptured burst disk. A deformable gasket contiguous to the burst disk seals the burst disk to the captured burst disk flange when the disk and the flange are pressed together. Attachment bolts are used to provide even application of pressure along the face of the burst disk and the captured burst disk flange.

  • Patent number: 6007142
    Abstract: A folding trailer which includes a slide-out room movable from a retracted position within the trailer to an extended position which adds additional living space to the inside of the trailer. The slide-out room includes a front wall, a rear wall and an exterior wall, with the floor attached therebetween and spaced above the trailer floor. A pair of lateral roller supports attached to the trailer floor along the front wall engages a roller track attached to the inside surface of the front wall. Similarly, a pair of lateral roller supports attached to the trailer floor on the other side of the slide-out room, and adjacent the rear wall, engages a roller track on an inner surface of the rear wall. A plurality of vertical roller supports attached to the trailer floor supports and contacts the lower surface of the slide-out floor.

  • Patent number: 5850646
    Abstract: A pressure reduction mattress construction for a liquid or gel bed having a flexible basin forming a cavity with inclines head and foot for surrounding and supporting a liquid or gel filled flotation bladder that is anchored to the head of the basin. The inclines made of a soft yielding material allow the head or foot of the bed to be easily raised as the liquid or gel moves toward the center of the bed. The head incline also serves to provide a soft yielding surface to support a patient after liquid or gel has naturally moved to the sacral area. The entire structure is then covered with a flexible and yielding hospital fabric cover, giving the bed the appearance of a conventional hospital mattress. An optional heater pad may be used with a fiber filled sacral/pelvic bladder placed over the heater pad.

  • Patent number: 5513400
    Abstract: A pressure reduction mattress construction for a liquid or gel bed having a flexible basin (10) forming a cavity (20) with inclines head (16H) and foot (16F) for surrounding and supporting a liquid or gel filled flotation bladder (30) that is anchored (36) to the head of the basin (10). The inclines (16F & 16H) made of a soft yielding material allow the head or foot of the bed to be easily raised as the liquid or gel (48) moves toward the center of bed. The head incline (16H) also serves to provide a soft yielding surface to support a patient after liquid or gel (48) has naturally moved to the sacral area (21). The entire structure is then covered with a flexible and yielding hospital fabric cover (40), giving the bed the appearance of a conventional hospital mattress. In some disclosed embodiments, an optional heater pad (22) may be used with a fiber (25) filled sacral bladder (26) placed over the heater pad (22) to prevent complete displacement of water over heater pad (22).

  • Patent number: 5002638
    Abstract: A method of papermaking in which a wet paper web is supported on press felt and passed through the nip between cooperating press rolls to extract water from the web. The felt, supporting the paper web, then travels through a span of distance and is passed around a heated dryer roll in the dryer section with the felt being interposed between the heated roll and the paper web. The felt is thus heated and insulates the paper web from the high temperature roll. The paper web is separated from the felt and travels around the remaining dryer rolls in the dryer section, while the heated felt is returned to the nip into position to support the wet paper web.
