Publication number: 20240175799Abstract: A particle detection system includes a light source configured to generate a light beam, a first collimator lens configured to channel the light beam into the chamber through a first sidewall, the chamber including openings on a second sidewall opposite the first sidewall, and a second collimator lens configured to channel light received from the openings to a light detector. A method for detecting particles flowing through a chamber includes generating a light beam, channeling the light beam into the chamber via a first collimator lens, detecting light escaped from the chamber via a plurality of openings formed at a second sidewall of the chamber opposite the first sidewall, at a light detector via a second collimator lens located outside the second sidewall, and determining parameters of the one or more particles flowing through the chamber based on the received escaped light.Type: ApplicationFiled: November 22, 2023Publication date: May 30, 2024Inventors: Gregory KOPANSKY, Stephen T.

Publication number: 20230236058Abstract: Methods and systems for in-fluid testing of electro optic liquid sensors are provided. The electro optic sensor has a light source and a light detector such that a first power state is applied to the light source to generate a first light for determining whether liquid is present within the electro optic sensor. Based on a determination that liquid is present within the electro optic sensor, a second power state is applied to the light source for generating a second light. The second power state having higher power over a shorter period of time than the first power state. The second light generated from the light source is reflected and the reflected second light is received at the light detector. The reflected second light is compared to a pulse current threshold value to determine whether the electro optic sensor is functioning properly.Type: ApplicationFiled: January 19, 2023Publication date: July 27, 2023Applicant: Eaton Intelligent Power LimitedInventors: Gregory Kopansky, John Joseph Zielinski
