  • Patent number: 11210321
    Abstract: In one embodiment, a web content management system is coupled to remote resources via a framework that has one or more corresponding adapters which enable editing of content by invoking editors which are native to the respective remote resources. The system retrieves a content item from a remote resource and stores a copy of the content item in a local repository, while the original content item remains in the repository of the remote resource. A content item can be selected in in a local authoring tool, causing the system to examine the content item's metadata to identify the source repository and invoke the native editor of the corresponding remote resource, enabling editing of the content item using the native editor. The copy of the content item in the local repository can then be synchronized to the edited version of the content item in the remote resource.

  • Patent number: 11208098
    Abstract: An advanced driving assistance system (ADAS) provides collision avoidance control for a host vehicle. The system can include one or more sensors mounted to the host vehicle and configured to sense a driving lane in which the host vehicle is traveling and to sense an external vehicle partially engaged in the driving lane. A controller controls steering, braking, or acceleration of the host vehicle on the basis of sensing information received from the sensor. The controller determines the external vehicle partially engaged in the driving lane as a target vehicle having at least a part thereof overlapping with a lane mark of the driving lane, and performs longitudinal braking or acceleration control or lateral steering control on the host vehicle based on lateral and longitudinal positional relationships between the host vehicle and the target vehicle.

  • Patent number: 11212912
    Abstract: Voids are introduced in a copper shape to reduce warpage experienced by a printed circuit board during a reflow process. Copper shapes on an outer layer of a printed circuit board may be used to connect large packages that include ball grid arrays to the printed circuit board. The copper shapes may induce warpage in the printed circuit board during the reflow process. Routing a mesh pattern of voids in the copper shapes may reduce solder ball joint cracking and pad cratering during reflow and make solder joints more reliable. The voids may make the copper shapes less ridged and change the copper heat dissipation profile to remove sharp warpage forces that cause solder joints to experience pad cratering. The voids may be 8 milĂ—8 mil cuts or indentations in the copper shape.
