  • Techniques and materials for calibrating optical sensors
    Patent number: 10794826
    Abstract: A calibration material may be used to calibrate an optical sensor to help ensure that the optical sensor produces accurate measurements. In some examples, the calibration material may be used to calibrate both turbidity measurements made by an optical sensor and fluorometric measurements made by the same optical sensor. The calibration material may be an aqueous mixture that includes water in an amount greater than 70 percent by weight of the composition, inorganic, water-insoluble, light-scattering particles, and a viscosity modifier in an amount effective to maintain the inorganic, water-insoluble, light-scattering particles in suspension in the composition. The composition can be non-fluorescing when exposed to ultraviolet light. In addition, in some applications, the composition is formulated of food safe ingredients, allowing the composition to be used in facilities that process consumable foods and beverages.
    Type: Grant

    Date of Patent: October 6, 2020
    Assignee: Ecolab USA Inc.
    Inventors: Richard Joseph Walsh, Evan Hendrickson, Caleb Power, Rodney Banks
  • Low solids surface coating compositions and use thereof
    Patent number: 10407591
    Abstract: The present invention is directed to low solid surface coating compositions and methods of using the same. The low solid surface coating compositions comprise a self-crosslinking polymer, a solvent, a surfactant, and water. The low solid surface coating compositions can preferably have a total solid content of less than 15%.
