  • Electro-optic liquid sensor enabling in-liquid testing
    Patent number: 10627281
    Abstract: An electro-optic liquid sensor may include a light source, a light detector, a prism, and a reflective optical member. The optical member may be arranged to reflect light emitted by the light source to the light detector when a liquid is disposed between the light source and the optical member. The electro-optic sensor may enable assessment of its operational state in the presence of liquid, thus improving on known electro-optic liquid sensors. A method of operating a sensor to assess the presence of liquid is disclosed.
    Type: Grant
    Filed: January 18, 2019
    Date of Patent: April 21, 2020
    Assignee: Eaton Intelligent Power Limited
    Inventors: Gregory Kopansky, Rolland James

  • Visual indicator with sensor
    Patent number: 9316522
    Abstract: A fluid level gauge includes a housing having a first end and a second end, and a window disposed in the housing, proximate to the first end. The fluid level gauge further includes an optical sensor disposed in the housing, proximate to the second end. A prism is disposed in the housing, between the optical sensor and the window, such that the prism and the window define a fluid chamber therebetween. The housing further includes a plurality of through holes that provides a fluid path from outside the housing to the fluid chamber.
