  • Publication number: 20110053139
    Abstract: Viruses and other bioagents are of high medical and biodefense concern and their detection at concentrations well below the threshold necessary to cause health hazards continues to be a challenge with respect to sensitivity, specificity, and selectivity. Ideally, assays for accurate and real time detection of viral agents and other bioagents would not necessitate any pre-processing of the analyte, which would make them applicable for example to bodily fluids (blood, sputum) and man-made as well as naturally occurring bodies of water (pools, rivers). We describe herein a robust biosensor that combines the sensitivity of surface acoustic waves (SAW) generated at a frequency of 325 MHz with the specificity provided by antibodies and other ligands for the detection of viral agents.

  • Patent number: 7841974
    Abstract: The present invention provides a container (10) suitable for providing insulation wherein the container has an inner shrink film (14) liner. The sidewalls of the container, which can be made from paperboard or other suitable material, are vented to allow ambient air to freely flow through the sidewall of the container during activation of the shrink film (14) with hot liquid or other suitable material. When the container is filled with material having a temperature of from about 130° F. to up to about 212° F., the shrink film (14) is activated and the container (10) provides excellent insulation, thereby allowing the container to be held in a consumer's hand for an extended period without causing burns or excessive discomfort. Method of making this container (10) are also provided.

  • Patent number: 7487448
    Abstract: Modular content framework and document format methods and systems are described. The described framework and format define a set of building blocks for composing, packaging, distributing, and rendering document-centered content. These building blocks define a platform-independent framework for document formats that enable software and hardware systems to generate, exchange, and display documents reliably and consistently. The framework and format have been designed in a flexible and extensible fashion. In addition to this general framework and format, a particular format, known as the reach package format, is defined using the general framework. The reach package format is a format for storing paginated documents. The contents of a reach package can be displayed or printed with full fidelity among devices and applications in a wide range of environments and across a wide range of scenarios.

  • Patent number: 7478325
    Abstract: Methods and systems permit rendering a text element formatted using unavailable or restricted fonts. In one embodiment, when producing a document that contains a restricted font, text portions formatted with the restricted font are processed into an alternate representation. A textual representation for the text portions and the additional representation(s) are embedded in a document or container. A unique representation for the restricted font file allows a consuming computing system to attempt to find the restricted font locally. Each textual representation is rendered using its corresponding restricted font, if the restricted font file is found. Otherwise, the additional representation(s) are used.

  • Patent number: 7422368
    Abstract: A CT scanner includes a base, two fixed portions extending transversely from the base, and a rocking beam pivotally attached to the base about an axis. The CT scanner includes four wheels that allow the CT scanner to move over a floor. A wheel is attached to each fixed portion, and a wheel is attached to each end of the rocking beam. If the CT scanner is positioned on a floor with an unlevel portion, the rocking beam rotates about the axis. One wheel attached to the rocking beam raises in a generally vertical direction, and the other beam attached to the rocking beam lowers in a generally vertical direction so all four wheels contact the floor, stabilizing the CT scanner and preventing rocking.
