US Patent:

20210003441, Jan 7, 2021

Filed:

Jun 29, 2020

Appl. No.:

16/914922

Inventors:

- Dublin, IE
David A. Weiser - Philadelphia PA, US
Thomas C. Gross - Honey Brook PA, US
Xin Pu - Chester Springs PA, US

International Classification:

G01F 23/292
G01D 11/26

Abstract:

A method of operating an electro-optic sensor includes disposing at least a portion of the electro-optic sensor in a liquid chamber, providing light from a light source of the electro-optic sensor at a first intensity, driving a light detector of the electro-optic sensor at a first sensitivity level, receiving, via the light detector, a first amount of light from the light source; determining whether liquid is present in the liquid chamber according to the first amount of light, providing light from the light source at a second intensity, driving the light detector at a second sensitivity level, receiving, via the light detector, a second amount of light from the light source, and/or confirming whether liquid is present in the liquid chamber according to the second amount of light. The first sensitivity level may be different from the second sensitivity level. An electro-optic sensor is also disclosed.

David Weiser - Philadelphia PA, US

International Classification:

G01N 15/06
G01N 27/74
F16N 29/04
G01N 33/28

Abstract:

A debris sensor may include a body including a first end and a second end, a ferrous particle sensor connected to the body, and a magnetic chip collector connected to the body at a position closer to the second end than the ferrous particle sensor. A plurality of magnets may be disposed closer to the second end than the magnetic chip collector. A non-ferrous particle sensor may be connected to the body and the non-ferrous particle sensor may be disposed closer to the second end than the plurality of magnets.
