  • Publication number: 20240175799
    Abstract: 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.

  • Patent number: 11966203
    Abstract: A system is disclosed, in accordance with one or more embodiments of the present disclosure. The system includes a metrology tool configured to acquire one or more measurements of a portion of a sample. The system includes a controller including one or more processors configured to execute program instructions causing the one or more processors to: generate a surface kinetics model output based on a surface kinetics model; determine an expected response of the surface kinetics model output to excitation by polarized light; compare the determined expected response to the one or more measurements; generate one or more metrics based on the comparison between the determined expected response and the one or more measurements of the sample; adjust one or more parameters of the surface kinetics model to generate an adjusted surface kinetics model; and apply the adjusted surface kinetics model to simulate on-sample performance during plasma processing.

  • Patent number: 11919058
    Abstract: The invention relates to a method for microbial remediation of underground water petroleum hydrocarbon contamination by regulating soil buffer capability, which comprises detecting the soil particle size of contaminated site soil, dividing the contaminated site soil into coarse-grained soil and fine-grained soil; dividing the contaminated site soil into high buffer capacity soil and low buffer capacity soil; and adjusting the composition and ratio of a biostimulant solution added to the contaminated site soil based on the classification of the contaminated site soil. The detecting step includes classifying soil with a particle size between 0.075 mm and 60 mm and a mass greater than or equal to 50% of the total mass as coarse-grained soil; and classifying soil with a particle size not greater than 0.075 mm and a mass greater than or equal to 50% as fine-grained soil.

  • Publication number: 20230117200
    Abstract: A flow separator includes a flow swirling arrangement and a particle collection space disposed in-line with an inlet and an outlet of a flow separator. The flow swirling arrangement includes a bladed arrangement disposed around a flow diverter. The particle collection space is an annular space disposed at an opposite end of a swirl region from the flow swirling arrangement. The annular space is disposed at the radially outward-most portion of the flow passage to collect particles via centrifugal force. A gas conduit may extend from the flow diverter through the particle collection space to separate out gas from the liquid of the input flow.

  • Patent number: 11300438
    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.
