摘要： Embodiments provide an optical sensor head and method of making an optical sensor head. In some cases the sensor head can be used as a fluorometric sensor to measure concentrations of substances within a liquid sample of interest. The sensor head includes a light source window and a detector window that transmit light between the sensor head and an analytical area. In some cases the windows include a ball lens positioned within a channel such that the ball lens and the channel create a seal between the interior and exterior of the sensor head.

摘要： A sensor array includes a plurality of sensors connected to two or more groups of wires such that individual sensors can be addressed. No two sensors are connected to the same two wires. The groups of wires are connected to multiplexers or the like to address particular wires connecting a unique sensor. Dramatically improved accuracy is obtained by connecting rectifiers in series with the sensors to significantly reduce reverse current through a sensor that can lead to significant errors. In some preferred embodiments, the array includes a plurality of temperature sensors, especially for use in measuring temperature at different depths in a body of water

摘要： An automated system for periodically sampling water bodies, such as lakes, and delivering the test results to a remote computer using a communication system. In particular, the system has a variable buoyancy profiler with a dynamic buoyancy compensator responding approximately linear to a water pressure created by an external water body so as to actively or passively interact with an external force or pressure thereby moving the profiler to a target depth.

摘要： A multichannel fluorosensor includes an optical module and an electronic module combined in a watertight housing with an underwater connector. The fluorosensor has an integral calibrator for periodical sensitivity validation of the fluorosensor. The optical module has one or several excitation channels and one or several emission channels that use a mutual focusing system. To increase efficiency, the excitation and emission channels each have a micro-collimator made with one or more ball lenses. Each excitation channel has a light emitting diode and an optical filter. Each emission channel has a photodiode with a preamplifier and an optical filter. The electronic module connects directly to the optical module and includes a lock-in amplifier, a power supply and a controller with an A/D converter and a connector. The calibrator provides a response proportional to the excitation intensity, and matches with spectral parameter of fluorescence for the analyzed fluorescent substance.

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.
