  • Publication number: 20060212835
    Abstract: A data-display system employs a display in which the representations of data objects are caused to move on the display in order to convey information about the represented data objects. In one example, icons in a link-analysis display that represent data objects satisfying a selection criterion are made to execute distinctive motion. In another example, three-dimensional models of moving bodies in whose features components of respective data objects are encoded are projected onto a screen plane, and the resultant values are used to generate the display.

  • Patent number: 7087256
    Abstract: An improved flavoring composition and process for brewing malt beverages is disclosed. In one embodiment of the invention, the flavoring composition is formed from a high solids percent, room temperature stable, partially aqueous composition of a potassium salt of iso-?-acids. Such composition may be added to the wort kettle or else used as a post-fermentation additive, preferably after dilution with demineralized water. In another embodiment, the flavoring composition comprises a mixture containing reduced (rho-) iso-?-acids in alkali metal salts form, ?-acids and hop oil. This latter composition is useful as a substitute for normal kettle extract, hops or hop pellets, allowing easy preparation of beer that resists formation of unpleasant, “skunk” flavors but has otherwise similar flavor and physical properties.

  • Patent number: 7033742
    Abstract: The present invention is directed to a method of forming a positive image in a photothermographic film exposed by electrons in a transmission electron microscope to form a latent image in the film. The photothermographic film has at least one imaging layer comprising a potentially negative-working emulsion, but wherein thermal development of unexposed silver salts in exposed areas relative to unexposed areas is inhibited when thermally developing the imagewise exposed assembly, thereby producing a positive image. The present invention is also directed to the processing of the photothermographic film in which a positive image characterized by high speed and discrimination is formed in the film when heated above 150° C.

  • Patent number: 7019894
    Abstract: A method and apparatus for automatically controlling the gain of an optical amplifier. The method begins by establishing a setpoint for ASE power within a given wavelength range generated by the optical amplifier. The pump power supplied to the optical amplifier is adjusted to maintain the ASE power at the established setpoint. The setpoint for the ASE power is adjusted based at least in part on changes in signal input power.

  • Patent number: 6992785
    Abstract: A data structure, document data stream, method and apparatus for identifying resources prior to printing. A print data stream structure is provided that can be specified at the beginning of a document or job, or on any page boundary in a document or job, and that identifies complex resources that are required by the pages that follow. This structure is processed by a print server, which uses the resource references to download any missing resources before printing of the following pages is started. Accordingly, print underruns are avoided by ensuring that complex resources are downloaded to the printer before the first page is initiated.

  • Patent number: 6964197
    Abstract: A testing apparatus for testing the level of retained gas at elevated pressure in plastic containers for carbonated beverages includes a manifold assembly for engaging the mouth of a test set of the containers. The apparatus additionally includes a gas supply for supplying a desired quantity of a selected gas to each container, the gas preferably helium. The apparatus further includes pressure measuring units for measuring the pressure in each container, and a data collection system coupled to the pressure measuring units for periodically collecting pressure data along with ambient temperature data as a function of time. The collected data can be analyzed to determine shelf life of the containers. Using helium, the shelf life determination can be accomplished in about 1/7th the time of conventional shelf life tests.
