  • Fluid level sensor and related methods
    Patent number: 10308035
    Abstract: In an embodiment, a fluid level sensor includes a sensor plate and a current source. The fluid level sensor also includes an algorithm to bias the current source such that current applied to the sensor plate induces a maximum difference in response voltage between a dry sensor plate condition and a wet sensor plate condition.
    Type: Grant
    Filed: February 8, 2018
    Date of Patent: June 4, 2019
    Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.
    Inventors: Andrew L. Van Brocklin, Paul A. Liebert, Adam L. Ghozeil, Scott A. Linn
