Patent number: 11590831Abstract: A device and a method for controlling a shading system of vehicle windows. A camera system detects image data of the head of a driver. The image data is evaluated to determine a gaze direction of the driver either as a function of a current pose of the head or body position of the driver ascertained based on the image data or as a function of eye positions of the driver determined based on image data. The shading system is controlled when the determined current gaze direction is looking in an interior rear view mirror, in the direction of the rear window, in the direction of one of the side windows, a reverse gear of the vehicle is set/activated, and the vehicle is in operation/activated. The control involves suspending or switching off a current shading/darkening of the rear window or of the side window in the gaze direction of the driver.Type: GrantFiled: July 15, 2020Date of Patent: February 28, 2023Assignee: MERCEDES-BENZ GROUP AGInventors: Manja Zedler, Tingting Zhang-Xu, Thomas Kälberer, Fabian Stiebert

Publication number: 20180167282Abstract: In a software-defined network (SDN) multiple servers and switches (the devices) connect into a (sub-)network under a (logically) centralized controller. As each device boots up it may have physically network connectivity but logically it is not connected to the SDN. In order to establish a logical connection the device must receive a network address assignment. There are legacy protocols for this purpose, e.g., DHCP that could be and have been adapted for use in software-defined networks. This invention specifies a different, enumeration-based method for address assignment in hierarchically-organized SDNs, which exploits the topological properties of the SDN for the purpose of device enumeration. This invention provides both Layer 2 and Layer 3 addresses for each device of the SDN.Type: ApplicationFiled: December 9, 2016Publication date: June 14, 2018Applicant: NoFutzNetworks Inc.Inventors: John Reumann, Zhang Xu, Lazaros Koromilas

Publication number: 20170244733Abstract: Methods and systems for intrusion detection include determining a causality trace for a flagged event. Determining the causality trace includes identifying a hot process that generates bursts of events with interleaved dependencies, aggregating events related to the hot process according to a process-centric dependency approximation that ignores dependencies between the events related to the hot process, and tracking causality in a reduced event stream that comprises the aggregated events. It is determined whether an intrusion has occurred based on the causality trace. One or more mitigation actions is performed if it is determined that an intrusion has occurred.Type: ApplicationFiled: January 26, 2017Publication date: August 24, 2017Inventors: Zhenyu Wu, Zhichun Li, Jungwhan Rhee, Fengyuan Xu, Guofei Jiang, Kangkook Jee, Xusheng Xiao, Zhang Xu
