Publication number: 20200261570Abstract: A compound immunopotentiator and application thereof relates to the preparation of the compound immunopotentiator and the application thereof in a foot-and-mouth disease vaccine of pigs. The foot-and-mouth disease vaccine of pigs is taken as a research subject, and on this basis, several immunopotentiators having obvious immunopotentiating effects are selected for the compound immunopotentiator, and an antigen/vaccine is mixed with the immunopotentiator to prepare a vaccine-immunized pig. After immunizing the vaccine containing the compound immunopotentiator, a window period for antibody production can be significantly shortened to 7 days; a LPB-ELISA antibody titer is significantly improved, and an antibody pass rate is significantly increased; an immune protection period is also significantly extended, at least up to 7 months; and the compound immunopotentiator is safe, and has no obvious side effects of immunity.Type: ApplicationFiled: July 28, 2017Publication date: August 20, 2020Inventors: Jin CHEN, Xiaoming YU, Qisheng ZHENG, Liting HOU, Yiwei WANG, Yuanpeng ZHANG, Xuwen QIAO, Jibo HOU

Patent number: 10644744Abstract: Methods and apparatuses are presented to reduce multiuser interference resulting from two or more overlapping ultra wideband (UWB) transmissions by randomizing the start time of packets and/or bursts within the packets. A random offset time may be generated for a packet, and transmission of the packet may be arbitrarily delayed by that random offset time, relative to an earlier time at which the packet is prepared for transmission. A random offset time may be generated for a pulse burst within a symbol of a packet, and transmission of the burst may be delayed by that random offset time, relative to a nominal transmission window within the symbol. The burst may therefore occupy a portion of a guard period following the nominal transmission window. Either procedure, or both procedures, may be used to reduce multiuser interference between two concurrently transmitted packets by randomizing overlap occurring between the bursts.Type: GrantFiled: August 21, 2018Date of Patent: May 5, 2020Assignee: Apple Inc.Inventors: Xiaoming Yu, Alejandro J. Marquez, Indranil S. Sen, Peter M. Agboh, Shang-Te Yang, Vusthla Sunil Reddy
