Patent number: 11888389Abstract: A power converter incudes a power factor correction circuit and a controller. The power factor correction circuit is configured to convert an input single-phase electrical power to a first DC electrical power. An active phase of the input single-phase electrical power is received in parallel through two of four conductors. A return phase of the input single-phase electrical power is received in parallel through two others of the four conductors. The power factor correction circuit is also configured to convert an input three-phase electrical power to the first DC electrical power. Three active phases of the input three-phase electrical power are received through three of the four conductors. The return phase is received through a fourth of the four conductors. The controller is configured to control the power factor correction circuit to operate in the single-phase input mode and the three-phase input mode in response to a control signal.Type: GrantFiled: August 24, 2022Date of Patent: January 30, 2024Assignee: Visteon Global Technologies, Inc.Inventors: Fiona E.

Publication number: 20210326674Abstract: This application discloses a content recommendation method performed at a computer device and belongs to the field of artificial intelligence. The method includes: acquiring a target user vector of a target user; determining n groups of seed user vectors according to the target user vector, each group of seed user vectors corresponding to a respective piece of candidate recommendation content; invoking a look-alike model to calculate a similarity between the target user vector and each group of seed user vectors, the look-alike model being used for calculating a similarity between user vectors based on an attention mechanism; and determining, among the n pieces of candidate recommendation content, target content to be recommended to the target user according to the respective similarities of the corresponding n groups of seed user vectors. This application can resolve a problem of relatively low accuracy of a recommendation method in the related art.Type: ApplicationFiled: June 29, 2021Publication date: October 21, 2021Inventors: Yudan Liu, Kaikai Ge, Xu Zhang, Leyu Lin, Xin Chen, Xiaobo Hao, Wei Wang, Kai Zhuang, Su Yan, Zhida Pan, Linyao Tang, Jing Zhang
