  • Fluid quality monitoring and filtration system
    Patent number: 10688422
    Abstract: A fluid filtration system may include a fluid filter assembly that includes a filter element configured to filter a fluid and a sensor probe incorporated into the fluid filter assembly. The sensor probe may include a chemically reactive material sensitive to at least one property of the fluid and at least a portion of the sensor probe may be exposed to the fluid.
    Type: Grant
    Filed: August 16, 2019
    Date of Patent: June 23, 2020
    Assignee: CUMMINS FILTRATION IP, INC.

  • Reflective diffractometric hydrogel sensor for biological and chemical detection
    Patent number: 8663563
    Abstract: A reflective diffractometric hydrogel sensor includes an upper layer, including a microfluidic chamber formed from a substantially transparent material and configured to contain a solution, a reflective diffraction grating positioned within the microfluidic chamber, the diffraction grating including a plurality of hydrogel strips configured to change in dimension in response to a stimulus, each hydrogel strip having a top surface coated with a reflective material and a bottom surface in contact with the upper layer substrate, and a reflective surface below the reflective diffraction grating wherein when a coherent light is incident upon and reflected from the upper layer at an angle substantially normal to the upper layer an interference diffraction pattern results, including a first diffraction mode, a light intensity of which indicates the relative distance between the top surfaces of the plurality of hydrogel strips and the reflective surface.
