Patent number: 10948331Abstract: A capacitive sensing system may include a fluid cup configured to receive a fluid, and processing circuitry and a capacitive sensor coupled to one another, the capacitive sensor is a distance separated from and in parallel with a top surface of the fluid in the fluid cup, the distance the capacitive sensor is separated from the top surface of the fluid being variable with a fill level of the fluid in the fluid cup. The capacitive sensor and the fluid in the fluid cup may form elements of a capacitor with a capacitance that is a function of at least the distance the capacitive sensor is separated from the top surface of the fluid. The processing circuitry may be configured to measure a change in signal corresponding to a change in capacitance of the capacitor and determine the fill level based on a magnitude of the change in signal.Type: GrantFiled: November 6, 2018Date of Patent: March 16, 2021Assignee: Electrolux Home Products, Inc.Inventors: George Marshall Horne, Thomas Josefsson, Stephen Smith, Paul Stoufer, Vasantha Chitta
