Patent number: 11463036Abstract: The disclosure uses the Carter's coefficient to correct the equivalent electromagnetic air gap length. And the specific permeance on both sides of the primary core is obtained. Then, the permeance on both sides based on the structure of the primary core is calculated. An equation is established by using the continuity principle of flux, thereby obtaining the air gap magnetomotive force model of current-carrying conductor. The slot vector diagram of magnetomotive force in short primary linear machine is illustrated according to that in the rotating machine. Then, based on the winding arrangement and vector combination, the amplitude and phase of various spatial harmonic wave of the three-phase winding are obtained. Finally, the characteristics of average component distribution of the current-carrying conductor are adopted to obtain the pulsating magnetomotive force generated by the three-phase winding of the linear machine.Type: GrantFiled: August 27, 2020Date of Patent: October 4, 2022Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Wei Xu, Jian Ge, Yi Liu, Yaping Zhang, Fei Xiong, Jingyue Su

Patent number: 11266744Abstract: Disclosed is a process for preparing a pharmacologically active compound, in which at least one internal conjugation site of an Fc domain sequence is selected that is amenable to conjugation of an additional functional moiety by a defined conjugation chemistry through the side chain of an amino acid residue at the conjugation site. An appropriate amino acid residue for conjugation may be present in a native Fc domain at the conjugation site or may be added by insertion (i.e., between amino acids in the native Fc domain) or by replacement (i.e., removing amino acids and substituting different amino acids). In the latter case, the number of amino acids added need not correspond to the number of amino acids removed from the previously existing Fc domain. This technology may be used to produce useful compositions of matter and pharmaceutical compositions containing them.Type: GrantFiled: November 30, 2018Date of Patent: March 8, 2022Assignee: AMGEN INC.Inventors: Colin V.

Patent number: 11042838Abstract: This disclosure describes interactive data processing systems configured to facilitate selection by a human associate of tentative results generated by an automated system from sensor data. In one implementation, an event may take place in a materials handling facility. The event may comprise a pick or place of an item from an inventory location, movement of a user, and so forth. The sensor data associated with the event is processed by an automated system to determine tentative results associated with the event. In some situations, an uncertainty may exist as to which of the tentative results accurately reflects the actual event. The system may then determine whether the event is to be merged with one or more temporally and spatially proximate events and, if so, the sensor data and tentative results for the merged event is sent to a human associate. The associate may select one of the tentative results.Type: GrantFiled: October 7, 2019Date of Patent: June 22, 2021Assignee: Amazon Technologies, Inc.Inventors: Fei Xiong, Sabarishkumar Iyer, David Echevarria Ignacio, Sridhar Boyapati, Caylan Lee, Jacques Daniel Thomas, Waqas Syed Ahmed, Danny Guan

Patent number: 10719168Abstract: Systems and methods are provided for improving the latency for display of ink during user creation of ink content with an object, such as a stylus, mouse, finger (or other touch input), or other drawing device. In order to reduce or minimize the time for display of ink content created by a user, aspects of the technology described herein generate predictive wet ink that can be displayed with actual wet ink. The predictive wet ink is calculated by extending an active ink segment a predictive distance. The predictive distance is intended to be a distance between a termination ink point for an active wet ink segment and a tip of the writing object. In one aspect, the predictive distance is calculated by determining the current latency period on a touch device and the velocity of the writing object.Type: GrantFiled: March 25, 2019Date of Patent: July 21, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Xiao Tu, Fei Xiong, Jianfeng Lin, Patrick Jee-An Poon
