  • Publication number: 20250053453
    Abstract: The invention relates to computer-implemented systems and methods that implement an innovative generative AI service based on proprietary expertise and industry knowledge. The generative AI service provides unique autonomous features, such as combining separate and distinct LLM responses and prompts to create unique results. Other autonomous features may include an ability to handle scaling and auto deployment of models and rerouting requests autonomously to ensure user load is balanced across the entire globally distributed Generative AI infrastructure estate. The generative AI service may further deploy new Production instances of models on demand by predefined system criteria as well as by explicit user request based on projected demand increase and/or the need for specific instance for further model fine-tuning.

  • Publication number: 20220212190
    Abstract: The technology described herein generally relates to microfluidic cartridges. The technology more particularly relates to a compressible pad applied to a microfluidic cartridge, wherein the microfluidic cartridge is configured to amplify nucleotides of interest, particularly from several biological samples in parallel, within microfluidic channels in the cartridge and permit detection of those nucleotides. Compressible pads of the present technology can be implemented in microfluidic cartridges having enhanced reaction chamber volumes, resulting in improved thermal uniformity and amplification efficiency in the cartridge. Assays using microfluidic cartridges of the present technology advantageously exhibit improved limit of detection (LOD) and improved limit of quantification (LOQ).

  • Patent number: 9196398
    Abstract: The present arrangement provides a communication cable having a plurality of twisted pair communication elements, a jacket surrounding the twisted pairs and a shield element disposed between the pairs and the jacket. The shield element is constructed as a tape substrate with a plurality of foil shielding elements disposed thereon, the foil shielding elements being formed in the shape of triangles and arranged on the substrate with at least a first foil shield element having a base of its triangle shape disposed substantially parallel to a longitudinal edge of the tape substrate. Each subsequent triangle is disposed on the tape substrate at a distance apart from the first triangle foil shielding element with a base of its triangle shape disposed substantially parallel to an opposite longitudinal edge of the tape substrate.

  • Patent number: 9186200
    Abstract: An electrosurgical generator is disclosed. The generator includes an RF output stage configured to supply electrosurgical energy to tissue via at least one active electrode configured to apply electrosurgical energy to tissue; sensing circuitry configured to measure impedance of tissue; and a controller. The controller is configured to determine occurrence of a tissue reaction as a function of a minimum impedance value and a predetermined rise in impedance, wherein tissue reaction corresponds to a boiling point of tissue fluid; generate a target impedance trajectory as a function of measured impedance and desired rate of change based on the tissue reaction determination, wherein the target impedance trajectory includes a plurality of target impedance values; and drive tissue impedance along the target impedance trajectory by adjusting the output of the electrosurgical generator to substantially match tissue impedance to a corresponding target impedance for at least a predetermined minimum time period.

  • Patent number: 8895858
    Abstract: A cable is provided containing one or more polymeric elements for reduction of crosstalk. The cable includes a plurality of unshielded twisted pairs, each of which is an insulated conductor pair twisted around one another, each having a different lay length. A jacket encloses the plurality of unshielded twisted pairs, where an unshielded twisted pair, has the longest lay length among the plurality of unshielded twisted pairs is positioned within the center of the jacket such that an axis of the twisted pairs that has the longest lay length substantially coincides with the central longitudinal axis of the cable. A plurality of bumper elements are disposed within the jacket in the interstices between said plurality of unshielded twisted pairs, where the bumper elements are profiled polymer structures.

  • Publication number: 20090211929
    Abstract: To invent a replacement case for a Universal Media Disc, better known as UMD. With front and back panels including pins and clasps to snap the two halves together. Pins with beveled ends and clasps with teeth are provided on the one half to connect the bottom half when snapped together.
