  • Patent number: 8495214
    Abstract: The present invention discloses a system and method for CSCF entity disaster tolerance and load balancing the system comprises P-CSCF entities, I-CSCF entities and S-CSCF entities, and further comprises a DNS Server. The present invention uses a DNS UPDATE message to report the load equivalent weight of the CSCF entity at regular time, so that the DNS Server can use the load equivalent weight when executing the load balancing strategy. It makes the disaster tolerance and load balancing in the IMS network be much easier to use and extend, thus reducing the load of the IMS network.

  • Publication number: 20130137594
    Abstract: Embodiments of the present disclosure generally pertain to systems and methods for performing amplicon rescue multiplex polymerase chain reaction (arm-PCR). In one embodiment, the system comprises a processor and a reader coupled to a control element. The control element is configured to control the operation of the processor and the reader based on a variety of settings. The processor is configured to receive a self-contained cassette for performing PCR amplification of DNA and/or RNA obtained from an organic specimen. The processor engages with the cassette and manipulates reagents within the cassette in order to amplify and detect the DNA from the specimen. The processor also causes the cassette to deposit the DNA on a microarray within the cassette. The reader is configured to receive the cassette after it has been processed by the processor and to capture an image of the microarray for transmission to the control element as test data.

  • Patent number: 8383068
    Abstract: A cassette for performing multiplex PCR is described. The cassette allows for the automated amplification and detection of multiple nucleic acid targets while limiting contamination. The device facilitates a two-amplification, two-primer PCR protocol which results in highly specific, highly sensitive and semi-quantitative amplification of multiple nucleic acid targets. The cassette contains a cavity, a base with a plurality of chambers, a movable pipette for the transfer of reagents and a detection area. The cassettes are single use, disposable devices which may be loaded with reagents needed for the detection of multiple targets. The cassettes may be used in a hospital or clinical setting to quickly screen clinical samples and detect the presence of infectious agents.

  • Patent number: 7811759
    Abstract: Described is a novel method for the detection of ncRNA molecules. The disclosed method is especially useful for the detection miRNA and siRNA. The method can be used to generate a profile of the ncRNA molecules present in a sample. In addition, using the methods of the present disclosure a ncRNA signature for a given disease or condition can be created. The ncRNA signature can be used for diagnostic purposes, therapeutic purposes and drug discovery purposes, as well as other uses.

  • Patent number: 7424675
    Abstract: A language input architecture converts input strings of phonetic text to an output string of language text. The language input architecture has a search engine, one or more typing models, a language model, and one or more lexicons for different languages. The typing model is configured to generate a list of probable typing candidates that may be substituted for the input string based on probabilities of how likely each of the candidate strings was incorrectly entered as the input string. The language model provides probable conversion strings for each of the typing candidates based on probabilities of how likely a probable conversion output string represents the candidate string. The search engine combines the probabilities of the typing and language models to find the most probable conversion string that represents a converted form of the input string.

  • Patent number: 7403888
    Abstract: A language input architecture receives input text (e.g., phonetic text of a character-based language) entered by a user from an input device (e.g., keyboard, voice recognition). The input text is converted to an output text (e.g., written language text of a character-based language). The language input architecture has a user interface that displays the output text and unconverted input text in line with one another. As the input text is converted, it is replaced in the UI with the converted output text. In addition to this in-line input feature, the UI enables in-place editing or error correction without requiring the user to switch modes from an entry mode to an edit mode. To assist with this in-place editing, the UI presents pop-up windows containing the phonetic text from which the output text was converted as well as first and second candidate lists that contain small and large sets of alternative candidates that might be used to replace the current output text.
