    摘要: A method for using optical parameters to monitor for a physiological event and/or a state prior to the physiological event includes the steps of: illuminating neural tissue with diagnostic light of a predetermined frequency at a predetermined location; detecting magnitude of optical scattering by neural tissue of the diagnostic light as a function of time; and determining a signature signal of the optical scattering of the diagnostic light before the physiological event in the neural tissue becomes clinically manifested. An apparatus includes a source of diagnostic light of a predetermined frequency for illuminating neural tissue at a predetermined location, a detector of optical scattering and/or optical absorption by neural tissue of the diagnostic light as a function of time, and a signal processor for determining a signature signal of the optical scattering and/or optical absorption of the diagnostic light before the physiological event becomes clinically manifested.

    摘要: A microflow analytical system includes a laminate pump assembly connectable with one or more sources of fluid, one or more pneumatic control pumps, a mixer, and a sensor. The laminate pump assembly is adapted to deliver predetermined volumes of the fluid(s) through a plurality of flow paths which are formed within layers of the assembly. Each flow path can include an inlet valve, a pump valve, and an outlet valve each of which are controllable by the pneumatic control pumps. A series of manifolds can be formed within the layers of the pump assembly to provide for simultaneous activation of selected flow paths. Delivered fluid volumes can be mixed in the mixer which, in some embodiments, may be integral with the laminate pump assembly. The sensor can measure one or more characteristics of the mixed fluids to determine one or more properties of the fluids.

    摘要: A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. Response data obtained by the detector is used to determine the concentrations of peracid and/or peroxide in the use composition based upon an evaluation function determined by a calibration method. The calibration method includes determining coefficients of the evaluation function based upon known concentrations, and measured response data of calibration samples.

    摘要: An H-bridge control circuit comprises an input stage, comparator stage, inverter stage. The operation of the H-bridge can be controlled by a single analog input signal provided by a feedback stage. Shoot-through protection is provided for the H-bridge circuit through the inclusion of a dead gap determined by inputs to the comparator stage. The dead gap can be adjusted, allowing for adjustment of the precision operation of the load. The H-bridge can be used to drive a bi-directional load such as, for example, a Peltier conditioner.
