Patent number: 8906695Abstract: In general, the present disclosure is directed toward a novel hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This device uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface.Type: GrantFiled: January 2, 2013Date of Patent: December 9, 2014Assignee: University of South CarolinaInventors: Thomas M. Crawford, Samir Y. Garzon

Publication number: 20140356964Abstract: An automatic analyzer detects measurement value abnormalities stemming from reaction process anomalies caused by the presence of foreign matter or bubbles. It is determined whether the results of concentration calculation based on light quantity data from multiple target detectors each fall within an applicable determination range. If the results fall within the determination range, an average value of the results of concentration calculation with the target detectors is calculated, and if not, an out-of-determination-range flag is given. A default fluctuation range is retrieved regarding the average value of the results of concentration calculation. The fluctuation range of the results of concentration calculation with the multiple target detectors is calculated.Type: ApplicationFiled: November 22, 2012Publication date: December 4, 2014Applicant: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Akihisa Makino, Masahiko Iijima, Akiko Watanabe

Patent number: 8900873Abstract: The invention relates to a method for continuously determining the concentration of at least one CN compound in an aqueous solution, wherein a carrier gas, for example compressed air, is introduced into the aqueous solution and the introduced carrier gas is fed at least partially to a gas analyzer, for example an HCN gas analyzer, the analysis data of which are considered in the determination of the concentration of the CN compound in the aqueous solution. In order to create advantageous method conditions, the temperature of the aqueous solution exposed to carrier gas is considered in the determination of the concentration of the CN compound.Type: GrantFiled: August 3, 2010Date of Patent: December 2, 2014Assignee: Voestalpine Stahl GmbHInventors: Franz Parzermair, Leopold Moser, Manfred Naderer

Patent number: 8895311Abstract: The present invention provides control methods, control systems, and control software for microfluidic devices that operate by moving discrete micro-droplets through a sequence of determined configurations. Such microfluidic devices are preferably constructed in a hierarchical and modular fashion which is reflected in the preferred structure of the provided methods and systems. In particular, the methods are structured into low-level device component control functions, middle-level actuator control functions, and high-level micro-droplet control functions. Advantageously, a microfluidic device may thereby be instructed to perform an intended reaction or analysis by invoking micro-droplet control function that perform intuitive tasks like measuring, mixing, heating, and so forth. The systems are preferably programmable and capable of accommodating microfluidic devices controlled by low voltages and constructed in standardized configurations.Type: GrantFiled: September 18, 2002Date of Patent: November 25, 2014Assignee: HandyLab, Inc.Inventors: Kalyan Handique, Karthik Ganesan, Sundaresh N.
