Abstract:

The present invention discloses the integration of programmable microfluidic circuits to achieve practical applications to process biochemical and chemical reactions and to integrate these reactions. In some embodiments workflows for biochemical reactions or chemical workflows are combined. Microvalves such as programmable microfluidic circuit with Y valves and flow through valves are disclosed. In some embodiments microvalves of the present invention are used for mixing fluids, which may be part of an integrated process. These processes include mixing samples and moving reactions to an edge or reservoir for modular microfluidics, use of capture regions, and injection into analytical devices on separate devices. In some embodiments star and nested star designs, or bead capture by change of cross sectional area of a channel in a microvalve are used. Movement of samples between temperature zones are further disclosed using fixed temperature and movement of the samples by micropumps.

International Classification:

G06F 7/00

US Classification:

701 296, 701 319

Abstract:

There is provided a method of predicting defects likely to occur in a vehicle over a predetermined period. The method includes receiving vehicle characteristic data regarding a vehicle under consideration, and comparing the received vehicle characteristic data with a defect database. The defect database includes information related to defects that have occurred in different vehicles and the mileage at which such defects occurred. The method additionally includes identifying defects that occurred in vehicles corresponding to use vehicle under consideration, and the mileage at which such defects occurred. Detects which fail to satisfy minimum count requirements are then filtered out, and the defects are then sorted in order of the highest defect count.

B01L 3/00

Abstract:

This application provides a bead with a covalently attached chemical compound and a covalently attached DNA barcode and methods for using such beads. The bead has many substantially identical copies of the chemical compound and many substantially identical copies of the DNA barcode. The compound consists of one or more chemical monomers, where the DNA barcode takes the form of barcode modules, where each module corresponds to and allows identification of a corresponding chemical monomer. The nucleic acid barcode can have a concatenated structure or an orthogonal structure. Provided are a method for sequencing the bead-bound nucleic acid barcode, for cleaving the compound from the bead, and for assessing biological activity of the released compound.
