Patent number: 11919811Abstract: A curing agent for disposal of municipal solid waste incineration (MSWI) fly ash and a preparation method and use method thereof are provided. In the present disclosure, a loofah nanofiber crystal, a rice husk ash (RHA), sodium hydroxide, and water are adopted as raw materials to prepare the curing agent, and the curing agent can effectively realize the safe disposal and curing of heavy metals in an MSWI fly ash. The highest curing rates of the curing agent for heavy metals Pb2+, Zn2+, Cd2+, Cr3+, and Cu2+ can reach 99.7%, 99.4%, 99.5%, 98.7%, and 99.5%, respectively. The special three-dimensional (3D) cross-linked network structure of the loofah nanofiber crystal and the excellent physical and chemical adsorption properties and ion exchange capacity of the RHA are fully used in the curing agent of the present disclosure.Type: GrantFiled: April 25, 2023Date of Patent: March 5, 2024Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Baomin Wang, Chengcheng Fan, Xiao Han, Tianru Li, Yunqing Xing, Xiong Zhang, Sai An, Ze Yu, Wanli Wang

Patent number: 11395388Abstract: There is presented a current driver and a corresponding method for driving a current-controlled component such as a semiconductor light source with a driving current. The current driver includes a current regulator for regulating the driving current, a power circuit, and an input stage. The input stage receives a first signal and a second signal and is operable in two phases. In the first phase, the first signal is used to power the power circuit, and in the second phase, the second signal is used to power the power circuit. The current driver may be implemented in an array of cells in which each cell includes a current driver coupled to a current controlled component. The array of cells may be a part of a display device.Type: GrantFiled: July 6, 2021Date of Patent: July 19, 2022Assignee: Dialog Semiconductor (UK) LimitedInventors: Ze Han, Nailong Wang, Zhenyu Song

Patent number: 10990559Abstract: A serial communication protocol for daisy-chained slave devices does away with the requirement for an entire byte of dummy clocks to be cycled between a slave's input and output, instead requiring a shorter set of dummy clock cycles which improves efficiency of a serial communication system. According to a specification of a serial communications protocol, data is exchanged between master and slave devices in communication frames. Each communication frame has a command portion and a data portion, and each respective portion may comprise packages of one or more bytes.Type: GrantFiled: September 12, 2019Date of Patent: April 27, 2021Assignee: Dialog Semiconductor (UK) LimitedInventors: Shaoxuan Wang, Yuchuan Shi, Ze Han, Lingxin Kong, Nailong Wang

Patent number: 10897151Abstract: A method and an apparatus for charge recycling. The method is comprised of the steps of receiving a charge at an energy storage element from a parasitic component, storing the charge at the energy storage element, and providing the charge stored at the energy storage element to a power supply's input or output. The step of receiving the charge at the energy storage element includes operating a discharging switch to selectively couple the parasitic component with the energy storage element and receiving the charge at the energy storage element via the discharging switch when the energy storage element and the parasitic component are coupled.Type: GrantFiled: December 6, 2018Date of Patent: January 19, 2021Assignee: Dialog Semiconductor (UK) LimitedInventors: Zhenyu Song, Junyue Sun, Nailong Wang, Ze Han, Xiaogang Zhao

Patent number: 9907131Abstract: An arbitrary alignment is provided for a series of pulses controlling a switch that in turn controls a current in an LED. Each pulse is generated according to a target time responsive to a reference time in a corresponding cycle of a synchronization clock. Each pulse has a leading portion that precedes its target time and a trailing portion subsequent to its target time. The arbitrary alignment defines the relative size of the leading portion to the trailing portion such that these relative sizes are incrementally changed across successive ones of the pulses.Type: GrantFiled: June 6, 2017Date of Patent: February 27, 2018Assignee: DIALOG SEMICONDUCTOR INC.Inventors: Lingxin Kong, Nailong Wang, Ze Han
