  • Patent number: 10180485
    Abstract: Described herein are systems and methods for improving performance of single-frequency (single-point, single-bin) discrete Fourier transform (DFT) detectors by elimination of systematic errors from the detector output. Calibration procedures known in the art for practical implementations of such detectors do not provide adequate reduction of these systematic errors thus reducing utilization of these detectors in useful applications and products. The described methods, systems and devices allow such detectors to measure both DC and AC signals and, in latter case, considerably expand the operation frequency range without any additional hardware. These methods enable wide practical applications of DFT detectors across diverse variety of fields: from monitoring health of mechanical structures and fluid properties to impedimetric measurements in electrochemistry, monitoring of corrosion and bioimpedance.

  • Patent number: 9173600
    Abstract: Described herein are devices, systems, and methods for determining the composition of fluids, and particularly for describing the identity and concentration of one or more components of a medical fluid such as intravenous fluid. These devices, systems and methods take multiple complex admittance measurements from a fluid sample in order to identify the identity and the concentration of components of the fluid. The identity and concentration of all of the components of the solution may be simultaneously and rapidly determined. In some variations, additional measurement or sensing modalities may be used in addition to admittance spectroscopy, including optical, thermal, chemical, etc.

  • Patent number: 8732938
    Abstract: An improved method of packaging a sensor is provided. The method includes the step of affixing a tuning fork to a platform. The tuning fork includes tines comprising one or more surfaces, with each tine further comprising an electrode and a piezoelectric material. An application specific integrated circuit (ASIC) is affixed to the platform. Electrical communication between the ASIC and the electrode of each tine is established for providing stimulus to the tuning fork and for receiving a response signal from the tuning fork. A protective layer is applied to cover the platform and a portion of the tuning fork while maintaining a portion of a surface of each tine free from the protective layer such that the surface can displace the fluid in contact therewith.

  • Patent number: 7334452
    Abstract: Methods for monitoring a fluid composition include placing a mechanical resonator in the fluid composition and oscillating the resonator. The resonator can be a tuning fork resonator having tines oscillated in opposite directions and in opposite phases. A variable frequency input signal can be varied over a predetermined frequency range and oscillate the mechanical resonator at less than 1 MHz. A frequency-dependent resonator response curve can be stored in a computer memory and fitted to a model curve to monitor the fluid. The resonator can be coated with a protective coating. The resonator can be treated with a functionality designed to change a resonance frequency of the resonator after being exposed to a selected target chemical and the resonance frequency monitored to detect presence of the target chemical.

  • Publication number: 20070272209
    Abstract: A sensor for sensing one or more properties of a vehicle fluid has a tuning fork resonator adapted to contact the fluid. The tuning fork resonator comprises two tines and is operable to oscillate so that the two tines move in opposite phase at a frequency of less than 1 MHz while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. In another aspect, a sensor includes a substrate and a flexural resonator on the substrate and adapted to contact the fluid. Circuitry for operation of the resonator is on the substrate. The resonator is adapted to receive an input signal and to oscillate while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. One suitable application for the invention is monitoring the condition of a vehicle engine oil.
