    Abstract: 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.

    Abstract: 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.

    Abstract: An optical detection sensor detects presence or absence of a product within a fluid delivery medium. An emitter directs radiation into the fluid delivery medium. Each of a plurality of detectors detects light within an associated one of a plurality of wavelength ranges transmitted through the fluid delivery medium. The output of each detector is further associated with at least one out-of-product threshold. A controller may further combine detector outputs, such as by multiplication, summation, or other mathematical operation, to produce additional measures of product presence or absence. Each combination output is also associated with at least one out-of-product threshold. The controller compares the output of each detector with the associated out-of-product threshold(s) and compares each combination output with the associated out-of-product threshold(s) to determine presence or absence of product within the fluid delivery medium. The sensor is able to determine presence or absence of a variety of products having different color, transparency or turbidity.

    Abstract: Se describe un sensor de detecci?n ?ptico que detecta la presencia o ausencia de un producto dentro de un medio de suministro de fluidos. Un emisor dirige radiaci?n dentro del medio de suministro de fluidos. Cada uno de una pluralidad de detectores detecta luz dentro de una pluralidad de escalas de longitudes de onda asociada transmitida a trav?s del medio de suministro de fluidos. La salida de cada detector se asocia adem?s con por lo menos un umbral de salida de producto. Un controlador puede combinar adem?s las salidas de detector, tal como mediante multiplicaci?n, suma u otra operaci?n matem?tica, para producir medidas adicionales de presencia o ausencia de producto. Cada salida en combinaci?n tambi?n es asociada con por lo menos un umbral de salida de producto. El controlador compara la salida de cada detector con los umbrales de salida de producto asociados y compara cada salida en combinaci?n con los umbrales de salida de producto asociados para determinar presencia o ausencia de producto dentro del medio de suministro de fluidos. El sensor es capaz de determinar la presencia o ausencia de una variedad de productos que tengan diferente color, transparencia o turbidez.
