Publication number: 20240089879Abstract: The present disclosure discloses a time service and positioning network system for an underground chain-shaped large space in a coal mine. The system adopts a base station-level network internal time synchronization method which takes an optical fiber time service as a main part and takes a satellite time service as an auxiliary part to construct a time service and positioning network system with an unified time within the ad-hoc network base stations, based on the ad-hoc network base stations linearly arranged in the underground chain-shaped large space in the coal mine. Through the network construction, the network stabilization and the network application, the system unifies the time reference of the base station-level network and improves the positioning accuracy of the network application by utilization of the base station-level network internal time synchronization method.Type: ApplicationFiled: September 30, 2022Publication date: March 14, 2024Inventors: Gongbo ZHOU, Chuansheng ZHANG, Fan JIANG, Lianfeng HAN, Shudong WANG, Xin LIU, Duifang GU, Tao WANG, Chuansong WANG, Libing WANG, Niansheng LIU, Fuxing SHI, Dongrun LIU, Lizheng LI, Zhencai ZHU

Patent number: 11850571Abstract: This disclosure provides polyamine sorbent compositions for the separation of metals from aqueous solutions. The polyamine sorbent compositions comprise a silica support, an aminosilane bound to the silica support, an epoxysilane bound to the silica support, and a polyamine where the polyamine is chemically tethered onto a solid silica support through via the epoxysilane. The polyamine may be further stabilized within the bulk sorbent through hydrogen bonding interactions with the aminosilane. The sorbent compositions resist leaching by H2O in an aqueous stream containing heavy oxyanion-based (and other) metals and demonstrate stability over a pH range of 2-14. The sorbent compositions are useful for the separation of metals from aqueous solutions. The cationic heavy metals are captured by the co-existing amine groups (—NH2, —NH, —N) from the polymeric network while additional metal capture capacity is derived from the introduction of a secondary silane linker.Type: GrantFiled: July 20, 2020Date of Patent: December 26, 2023Assignee: United States Department of EnergyInventors: McMahan L Gray, Brian W.

Patent number: 11014391Abstract: A printing system receives a print request containing patterns of marks to be printed on print media to produce printed output. A processor evaluates the print request to identify non-marking areas and identify different printing densities of the patterns of marks. The processor alters the patterns of marks to create hidden features on the printed output by adding a uniform printed background to the non-marking areas and adding different printing densities of fluorescent spots to different areas of the patterns of marks. The different printing densities of the fluorescent spots are based on the different printing densities of the patterns of marks and on the size of the hidden features. A printing device prints the print request on the print media to produce the printed output.Type: GrantFiled: September 16, 2019Date of Patent: May 25, 2021Assignee: Xerox CorporationInventors: Eliud Robles Flores, Tara L.
