Patent number: 11975989Abstract: An integrated method for clearance, collection and capture of internal pollutants and algae at the bottom of a lake include the following steps: selecting areas where the pollution level is high, and organic or inorganic particulate matter is prone to accumulation and carrying out trenching operations at the bottom of the lake to form a plurality of traps; and removing the sludge and algae inside the traps and clearing the sediment inside the traps, for subsequent internal pollution control when the surface-layer sludge on both sides of the traps almost fills up the traps. This method makes use of the hydrodynamic disturbances of waves formed by natural wind energy and lake currents to continuously transport sludge with a high pollution level and a small specific gravity and algae in the surface layer of the lake bottom, which are rich in organic debris, to artificially built traps.Type: GrantFiled: November 11, 2020Date of Patent: May 7, 2024Assignee: NANJING INSTITUTE OF GEOGRAPHY & LIMNOLOGY, CHINESE ACADEMY OF SCIENCESInventors: Weiping Hu, Yihui Zhang, Jiancai Deng, Weiwei Xu

Publication number: 20240076860Abstract: An automatic faucet for a wash basin includes a control box. The control box includes a control box body, a solenoid valve, and a manual control member. Both the solenoid valve and the manual control member can control whether water flows out from a mixed water outlet of the control box body or not. The automatic faucet can realize a manually-operated spray function for use in an emergency when the solenoid valve fails.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Xingui Zhang, Yihui Chen, Mouyong Lin

Publication number: 20240068214Abstract: A water discharge structure and a sensor-operated water discharge device are disclosed. The water discharge structure includes a valve core seat having independent cold water, hot water and sensor-operated mixed water flow channels. An accommodating chamber is disposed inside the sensor-operated mixed water flow channel for accommodating a solenoid valve that controls opening and closing of the sensor-operated mixed water flow channel. The valve core seat has a cold water outlet, a hot water outlet, a sensor-operated mixed water inlet and a mechanically-operated mixed water inlet that are located on a same end face of the valve core seat. It is convenient to assemble the valve core seat and the valve core of the sensor-operated water discharge device. The overall assembly of the sensor-operated water discharge device can be realized when it leaves the factory, and the installation operation can be simplified for the user.Type: ApplicationFiled: August 31, 2022Publication date: February 29, 2024Inventors: Xingui Zhang, Yihui Chen, Mouyong Lin

Publication number: 20220349924Abstract: The present invention disclosed a method for calculating an oscillation damping ratio of a power grid, and relates to the field of power system operation and control. When a power system oscillates, an oscillation period, two oscillation extreme points, and an oscillation direct current component start to be detected. Then an oscillation decay time constant is calculated according to the two oscillation extreme points and the oscillation direct current component. The oscillation damping ratio is calculated through the oscillation decay time constant and the oscillation period. Compared with a conventional fitting method, the conventional fitting method cannot calculate and analyze the oscillation damping ratio in a cast that a complete oscillation waveform is not obtained. The method proposed by the present inventive patent may complete the calculation of the oscillation damping ratio in a case of obtaining 2 pieces of data, so as to accelerate the speed of calculation.Type: ApplicationFiled: September 4, 2020Publication date: November 3, 2022Inventors: Yihui ZHANG, Libin WEN, Guangshi LIU, Qian DOU, Dongshan HUANG, Xiaoming WANG, Zhiyuan SUN, Guangling LU, Mingpo LI, Mosi LIU, Hao QIU, Xiaoyin QIU, Zhiyang YAO, Wei ZHANG

Patent number: 10840536Abstract: The present invention provides electronic systems, including device arrays, comprising functional device(s) and/or device component(s) at least partially enclosed via one or more containment chambers, such that the device(s) and/or device component(s) are at least partially, and optionally entirely, immersed in a containment fluid. Useful containment fluids for use in containment chambers of electronic devices of the invention include lubricants, electrolytes and/or electronically resistive fluids. In some embodiments, for example, electronic systems of the invention comprise one or more electronic devices and/or device components provided in free-standing and/or tethered configurations that decouple forces originating upon deformation, stretching or compression of a supporting substrate from the free standing or tethered device or device component.Type: GrantFiled: February 5, 2014Date of Patent: November 17, 2020Assignees: The Board of Trustees of the University of Illinois, Northwestern UniversityInventors: John A.

Patent number: 10192830Abstract: The present invention provides electronic circuits, devices and device components including one or more stretchable components, such as stretchable electrical interconnects, electrodes and/or semiconductor components. Stretchability of some of the present systems is achieved via a materials level integration of stretchable metallic or semiconducting structures with soft, elastomeric materials in a configuration allowing for elastic deformations to occur in a repeatable and well-defined way. The stretchable device geometries and hard-soft materials integration approaches of the invention provide a combination of advance electronic function and compliant mechanics supporting a broad range of device applications including sensing, actuation, power storage and communications.Type: GrantFiled: April 3, 2017Date of Patent: January 29, 2019Assignees: The Board of Trustees of the University of Illinois, Northwestern UniversityInventors: John A.
