  • Patent number: 7850812
    Abstract: Described is a method of making a laminated paint roller wherein a perforated strip of thermoplastic material is advanced, the perforated strip having holes there-through. A lubricant is applied to the inner surface of the advancing perforated strip of thermoplastic material. The lubricated, perforated strip of thermoplastic material is helically wound around a cooled mandrel so as to form a helically wound strip wherein the inner surface of the perforated strip faces the cooled mandrel and the outer surface of the perforated strip faces away from the cooled mandrel. The wound perforated strip is advanced along the cooled mandrel. A layer of adhesive is applied onto an outer surface of the wound perforated strip. A strip of composite cover material is helically wrapped about the wound strip and over the layer of adhesive, the outer surface of the composite cover material comprising a pile fabric, and the inner surface of the composite cover material comprising thermoplastic.

  • Publication number: 20100310623
    Abstract: An integrated scaffold for bone tissue engineering has a tubular outer shell and a spiral scaffold made of a porous sheet. The spiral scaffold is formed such that the porous sheet defines a series of spiral coils with gaps of controlled width between the coils to provide an open geometry for enhanced cell growth. The spiral scaffold resides within the bore of the shell and is integrated with the shell to fix the geometry of the spiral scaffold. Nanofibers may be deposited on the porous sheet to enhance cell penetration into the spiral scaffold. The spiral scaffold may have alternating layers of polymer and ceramic on the porous sheet that have been built up using a layer-by-layer method. The spiral scaffold may be seeded with cells by growing a cell sheet and placing the cell sheet on the porous sheet before it is rolled.

  • Patent number: 7846283
    Abstract: A method for reducing cost and weight in paint roller manufacturing processes and other continuous processes for producing tubular goods from polymers. The method may utilize a perforated substrate such as a perforated polypropylene strip or may include a perforating step which removes overage from an unperforated substrate. The perforated substrate is fed onto a mandrel to form a tube. Adhesive is applied upon the outer surface of the perforated substrate. A cover may be applied about the tube, and the resulting product is then cut into finished-size paint rollers. The removal of the overage results in a reduction in the weight of the paint roller. In certain embodiments the overage from a perforation step is collected, and may be reused in a subsequent implementation of the method or resold.

  • Patent number: 7848570
    Abstract: To provide a memory efficient method and system for statistical data accumulation and processing, data is divided into multiple data zones and divided into subgroups of memories. A separate memory bin is assigned for each of the subgroups, and this memory bin is shared between various two data zones in each subgroup for processing and accumulation. In this scheme, the histogram data in each location of the separate memory bin for the previously accumulated data zones is processed before updating the stored value for the data zone requiring data accumulation.

  • Publication number: 20100306310
    Abstract: The present invention provides a method and system for regulating bandwidth by regulating data transmission between a transmission station and a receiving station at an application level. By regulating bandwidth at the application level, there is no need for complicated network programming required at a low level, such as the device level, whenever changes to the bandwidth need to be made. As such, bandwidth can be easily regulated and customised without having to carry out complicated network programming.

  • Publication number: 20100304678
    Abstract: Functionality is described by selecting a channel in an environment in which non-privileged entities have subordinate access rights to spectrum compared to privileged entities. The functionality operates by identifying spectrum that is available to all nodes involved in communication (where the nodes are associated with non-privileged entities). The functionality then generates a suitability assessment for each candidate channel within the available spectrum. The functionality selects a channel having the most desirable suitability assessment. The functionality can form a suitability assessment for a candidate channel of arbitrary width, e.g., by combining suitability assessments associated with constituent spectrum units within the candidate channel.

  • Publication number: 20100301992
    Abstract: Functionality is described for discovering a channel within an environment in which non-privileged entities have subordinate access rights to spectrum compared to privileged entities. The functionality operates by investigating spectrum units within the spectrum for the presence of the channel. In one case, the functionality operates by investigating the spectrum units in linear succession; in another case, the functionality advances in a staggered fashion over the available spectrum. Functionality is also described for handling disconnection by a node from a channel. The functionality allows the node to convey its disconnection status to other communication participants. In one case, various aspects of the functionality are implemented by performing analysis in the time domain.
