    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.

    摘要: Embodiments of the invention provide devices and methods for measuring fluid volume. Devices according to some embodiments include a chamber, having a pair of gears rotatably mounted therewithin. Fluid flow through the chamber causes rotation of the gears, such that each rotation and/or partial rotation results in a known volume of the fluid passing through the chamber. An optical sensor positioned outside of the chamber, can view the rotating gears through a substantially transparent chamber wall. The optical sensor can view an optical characteristic of one or both of the gears, and based upon this data, fluid volume, flow rate, and/or flow direction can be determined. Devices and methods disclosed herein can provide for improved precision in fluid flow meter measurement. In addition, the devices and methods used herein can be more durable and easier to fabricate than previously known positive displacement flow meters.

    摘要: At least one single link of a conveyor chain is configured to support a tension load cell. A main body portion of the link includes a central cavity sized to contain the load cell, which has been inserted therein through an opening of the main body portion, and at least one auxiliary cavity to contain at least one battery cell and circuitry. A cap portion of the link closes off the opening into the cavity to enclose the load cell therein. One or both of the main body and cap portions may include a bore to receive a fastener for attaching to an end of the inserted load cell, and both portions include a bore oriented to receive a pin of a mating dual link of the conveyor chain. The cap portion may also include anti-rotation surfaces to mate with one or both of: the load cell and the opening.

    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.
