  • Patent number: 11935629
    Abstract: Aspects of the present disclosure include methods for identifying a set of fluorophore-biomolecule reagent pairs for characterizing a sample by flow cytometry. Methods according to certain embodiments include calculating a spectral spillover spreading parameter for a plurality of fluorophores, pairing each fluorophore with a biomolecule that is specific for a biomarker of a cell in the sample to generate a plurality of fluorophore-biomolecule reagent pairs, generating an adjusted spillover spreading matrix for the fluorophore-biomolecule reagent pairs based on the spectral spillover spreading parameter of each fluorophore and a biomarker classification parameter and identifying an optimal set of fluorophore-biomolecule reagent pairs based on the calculated spillover spreading values from the adjusted spillover spreading matrix. Systems and non-transitory computer readable storage medium for practicing the subject methods are also provided.

  • Patent number: 8907639
    Abstract: A boost power converter system according to one embodiment includes an input voltage high-side node; an inductor coupled to the input voltage high-side node at a first terminal of the inductor; a power switch coupled to the inductor at a second terminal of the inductor; a drive circuit configured to control the power switch such that the boost power converter system operates in a discontinuous conduction mode when a load current drops below a critical conduction threshold; and a damping switch configured to enable current flow from the power switch at the second terminal of the inductor to the input voltage high-side node, wherein the damping switch is closed when the power switch is open and the damping switch is opened when the power switch is closed.

  • Publication number: 20040014017
    Abstract: This invention relates to a system and method for effective and efficient learning (EEL), with interactive, adaptive, and individualized computer-assisted instruction to students, which can be implemented on the Internet, network connected computers, single computer or other devices including designated device. More particularly the system and method includes for each student a student dynamic record adapted to the student which contains the student's personal profile that includes learning style, ability (analysis, understanding, memory, reasoning, deduction, generalizing, applying, and speed), personality, interest, and background knowledge. The student dynamic record reflects its student's behavior in responding to instruction. The EEL system also includes an AI engine consists of a self-improved dynamic rule base, which selects the materials in a knowledge base to control the instructional progress, and guides its student according to educational and psychological theories.

  • Patent number: 6373256
    Abstract: A low battery detect circuit with digitally programmable detect levels. The programmable low battery detect circuit includes a comparator that compares a stable reference voltage against a battery-supplied voltage as divided down by a digitally programmable resistive divider chain. By programmably varying the resistance of the divider chain, the low battery detect threshold level can be varied depending on the requirements of the application.
