Patent number: 11919058Abstract: 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.Type: GrantFiled: May 31, 2023Date of Patent: March 5, 2024Assignee: CHENGDU UNIVERSITY OF TECHNOLOGYInventors: Shengyan Pu, Peng Wang, Shibin Liu, Xin Wang, Hui Ma, Pei An

Patent number: 11912595Abstract: The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.Type: GrantFiled: February 22, 2023Date of Patent: February 27, 2024Assignee: CHENGDU UNIVERSITY OF TECHNOLOGYInventors: Shengyan Pu, Hui Ma, Yuming He, Xiaoguang Wang, Guangyong Zeng, Yi Chen, Dong Yu, Wenwen Ji

Publication number: 20230061439Abstract: A motor controlling system is disclosed. The motor controlling system is integrated in an apparatus having roll-to-roll mechanism, and comprises a linear light source, N number of cameras and a modular electronic device. When a roll of continuous web material is discharged by an unwinding unit of the roll-to-roll mechanism so as to be further transferred to an inspection unit, the cameras are controlled by the modular electronic device to capture a plurality of time-consecutive material image frames. Subsequently, the modular electronic device conducts a defection inspection for a segment of the continuous web material by applying an image process to the material image frames. As a result, in case of there being at least one defect found, the modular electronic device stops a plurality of motors of the apparatus from running, thereby making the segment of the continuous web material be positioned on an inspection platform.Type: ApplicationFiled: August 1, 2022Publication date: March 2, 2023Inventors: Feng-Tso Sun, Yi-Ting Yeh, Feng-Yu Sun, Po-Han Chou, Yun-Yi Chen, Hui-Pu Chang, Jyun-Tang Huang

Patent number: 11203494Abstract: A system for sorting moving objects is disclosed. The system comprises a light source, an image capturing device, a controlling and processing device, and an object sorting device. Particularly, the controlling and processing device is configured to decide a first setting parameter so as to apply a parameter adjustment to the light source, and is also configured to decide a second setting parameter so as to apply an parameter adjustment to the image capturing device. After deciding an object classifier based on the first setting parameter, the second setting parameter, and object images received from the image capturing device, the object sorting device is controlled to apply an object sorting process to the of objects that are delivered by the belt conveyor, thereby sorting the objects into at least two object group consisting of a normal object group and a defective object group.Type: GrantFiled: July 23, 2020Date of Patent: December 21, 2021Assignee: KAPITO INC.Inventors: Feng-Tso Sun, Yi-Ting Yeh, Feng-Yu Sun, Hui-Pu Chang
