  • Publication number: 20040267837
    Abstract: The invention provides a system and method for updating network appliances using urgent update notifications. The network appliances periodically initiates connection to “poll” updates from the update server and the update server collects IP addresses from the connections and updates an IP address log. The update server obtains updates for the network appliances and determines whether a particular update is urgent. When an urgent update is available, the server delivers an urgent update notification (UUN) to each known network appliance through an existing port used for messaging. Each network appliance receives the UUN and distinguishes it from other messages. In response to the UUN, each network appliance automatically connects to the server, obtains the urgent update and installs the urgent update.

  • Publication number: 20040186034
    Abstract: Generally speaking, the present invention is a water-soluble copolymer film comprising a hydrolyzed copolymer of vinyl acetate and a second monomer, the resultant polyvinyl alcohol copolymer having a degree of hydrolysis, expressed as a percentage of vinyl acetate units converted to vinyl alcohol units, of from about 90% to 100%. The second monomer is preferably selected from the group of monomers having carboxylate functionality or sulfonate functionality. The resulting water-soluble copolymer film is disclosed for use in making pouches to contain a unit dose of liquid detergent, such as a liquid laundry detergent. However, it is an aspect of the copolymer film that film solubility is not significantly affected adversely by the detergent. Such film produces pouches having a greater storage shelf-life over prior art water-soluble film.

  • Publication number: 20040091879
    Abstract: Methods for rapidly detecting single or multiple sequence alleles in a sample nucleic acid are described. Provided are all of the oligonucleotide pairs capable of annealing specifically to a target allele and discriminating among possible sequences thereof, and ligating to each other to form an oligonucleotide complex when a particular sequence feature is present (or, alternatively, absent) in the sample nucleic acid. The design of each oligonucleotide pair permits the subsequent high-level PCR amplification of a specific amplicon when the oligonucleotide complex is formed, but not when the oligonucleotide complex is not formed. The presence or absence of the specific amplicon is used to detect the allele. Detection of the specific amplicon may be achieved using a variety of methods well known in the art, including without limitation, oligonucleotide capture onto DNA chips or microarrays, oligonucleotide capture onto beads or microspheres, electrophoresis, and mass spectrometry.

  • Patent number: 6717912
    Abstract: The present invention is a shared buffer architecture that dynamically allocates buffer size to each of multiple sources depending on buffer pool utilization, estimated per-connection offered load, and the total number of connection established within a given class of service. When the buffer pool is almost empty, each source is allocated a large buffer space, proportional to its estimated offered load. When the buffer pool is more full each source is allocated a reduced buffer space, while maintaining the proportional weighting relationship. The invention keeps track of the amount of input per source and dynamically allocates a proportionate amount of buffer space in the buffer memory for that source. The dynamic allocation is made as a function of the fullness of the memory allocation for all sources. Additionally, thresholds are modulated dynamically as the number of established connections within a given class modulates, providing a predictive aspect to the system, with respect to congestion control.

  • Publication number: 20030190609
    Abstract: A method for generating address/capture tags for use in a sensitive and rapid flow-cytometry based assay for the multiplexed analysis of SNPs based on polymerase-mediated primer extension using microspheres as solid supports is described. Single-nucleotide polymorphisms (SNPs) are the most abundant type of human genetic variation. These variable sites are present at high density in the genome, making them powerful tools for mapping and diagnosing disease-related alleles. Subnanomolar concentrations of sample in small volumes (10 ml) can be analyzed at rates greater than one sample per minute, without a wash step. Genomic analysis using multiplexing microsphere arrays, enables the simultaneous analysis of dozens, and potentially hundreds of SNPs per sample. The method has been tested by genotyping the Glu69 variant from the HLA DPB1 locus, a SNP associated with chronic beryllium disease, as well as HLA DPA1 alleles.
