Patent number: 12219536Abstract: The present disclosure relates to systems and methods for connecting to a wireless network. The methods may include obtaining, within a dwell time, at least one packet transmitting on a current channel among a plurality of predetermined channels, wherein the plurality of predetermined channels at least include a target channel on which a connection to the wireless network is to be established; determining a matching score of the current channel based on the at least one packet, wherein the matching score reflects a likelihood that the current channel is the target channel; and determining, based on the matching score, an additional dwell time for continuing dwelling on the current channel to further evaluate the likelihood that the current channel is the target channel.Type: GrantFiled: December 23, 2021Date of Patent: February 4, 2025Assignee: ZHEJIANG DAHUA TECHNOLOGY CO., LTD.Inventors: Long Du, Hui Li

Patent number: 12081637Abstract: Disclosed is a framework for providing microservices for database with embedded container service in a container cloud platform. The framework includes a container cloud manager for performing distributed management of resources in a data center. The container cloud manager includes an orchestrator with a flexible job scheduler and operator pool. The flexible job scheduler and container cloud master form a flexible job management platform for managing jobs of the data center. The flexible job management framework can isolate various types of jobs as well as mix various jobs for efficient usage of hosts or resources in the data center. The operator pool includes optional components of a database. The orchestrator facilitates quick customization and release of database products, such as a HANA database with optional services, as requested by a user in the container cloud platform.Type: GrantFiled: May 11, 2023Date of Patent: September 3, 2024Assignee: SAP SEInventors: Long Du, Le Zhang, Yu Wang

Patent number: 12013959Abstract: In an example embodiment, a hardware mechanism for protecting user-level software from privileged system software is leveraged to protect in-memory databases in container implementations in a cloud. This hardware mechanism takes the form of an enclave. An enclave is a portion of a CPU that shields application code and data from accesses by other software, including higher-privileged software. Memory pages belonging to an enclave reside in the enclave page cache (EPC), which cannot be accessed by code outside of the enclave. This helps ensure that (1) applications built on top of in-memory database are securely trusted, (2) and a trusted path architecture is provided for enclaves allowing in-memory databases to run securely on top of untrusted cloud platform.Type: GrantFiled: April 26, 2023Date of Patent: June 18, 2024Assignee: SAP SEInventor: Long Du

Patent number: 11954122Abstract: In an example embodiment, a solution is used to provide container volume replication via a container storage replication log and volume buffer synchronization, which is built on top of a container cloud platform whose container metadata and replication runtime configuration are all managed by a storage manager (a service orchestrated by its job scheduler and service orchestrator). This container volume replication ensures the data security for a long-running service in the container. In the case of any disaster, the in-memory database and application data inside of the container can be recovered via volume replication. This provides container volume replication for long-running containerized applications whose states keep changing.Type: GrantFiled: January 23, 2023Date of Patent: April 9, 2024Assignee: SAP SEInventors: Long Du, Yu Wang

Patent number: 11902284Abstract: A method of tenant user management in cloud database operation can be implemented. The method can receive an original job request from a user for a database service, wherein the original job request can include a login credential of the user. The method can authenticate the login credential of the user by a scheduler, verify the user has privileges for the original job request by the scheduler, create a modified job request from the original job request by the scheduler based on a predefined role corresponding to the privileges of the user, send the modified job request from the scheduler to a database service platform, and allocate an instance of database service to the user in response to the modified job request.Type: GrantFiled: March 5, 2021Date of Patent: February 13, 2024Assignee: SAP SEInventors: Long Du, Haoxing Hou, Le Zhang, Jun Zhang

Patent number: 11899687Abstract: In an example embodiment, a solution is used to provide for multiple and concurrent web application accessing of a database in a database-as-a-service (DBaaS) framework. More particularly, a cloud solution is provided on a DBaaS for leveraging Docker network functionality to provide a virtual Internet Protocol (IP) address pool, while utilizing in-memory database technology to set up an entire accessing solution for multiple and concurrent DBaaS users and web applications, which serve the data-intensive jobs to the in-memory database. This allows for improved functionality, performance, concurrency, and handling of network stress.Type: GrantFiled: April 25, 2022Date of Patent: February 13, 2024Assignee: SAP SEInventors: Yu Wang, Long Du, Le Zhang, Xiaodan Yuan

Patent number: 11803514Abstract: In an example embodiment, a solution is used to provide for a highly efficient image dispatch system for container-based in-memory databases in a database-as-a-service framework that provides storage and bandwidth cost savings and introduces advanced features of container techniques. This solution makes best use of the advantages of the concurrent and distributed capabilities of in-memory databases in a database-as-a-service framework. A container operator manager provides operators for various uses, such as the “diff” operator and the “merge” operator. A dispatch manager acts as a centralized service for diff content maintenance, patch publication and management of dispatch worker nodes. A patch worker on each node has the capabilities to execute the specified patching and validation between the images located on each side of the in-memory database in the database-as-a-service framework.Type: GrantFiled: June 17, 2022Date of Patent: October 31, 2023Assignee: SAP SEInventors: Yu Wang, Long Du, Le Zhang

Publication number: 20230321846Abstract: Robotic systems with griping mechanisms, and related systems and methods are disclosed herein. In some embodiments, the robotic system includes a robotic arm and an end-of-arm tool coupled to the robotic arm. The end-of-arm tool can include a frame and an actuator system coupled to the frame. The end-of-arm tool can also include a first clamping component, a second clamping component, and a third clamping component each coupled to the frame. The third clamping component is positioned peripheral to the second clamping component with respect to the first clamping component and includes one or more extension portions extending toward the first clamping component. The actuator system can be coupled to the first, second, and/or third clamping components to move the first, second, and/or third clamping components along a transverse axis of the end-of-arm tool.Type: ApplicationFiled: April 6, 2023Publication date: October 12, 2023Inventors: Lei Lei, Xutao Ye, Xu Chen, Yixuan Zhang, Zhili Lai, Long Du, Pai Zheng, Rosen Nikolaev Diankov

Patent number: 11681549Abstract: In an example embodiment, a new solution is provided for an in-memory database provided in a cloud as a service that enables “job cross running” instead of “parallel job running.” Specifically, job scripts are clustered based on a shared service. A primary job script in the cluster is compiled and executed, but secondary job scripts in the cluster are not compiled until after the execution of the primary job script has begun. A mock library is inserted into each of the secondary job scripts to cause service calls for the shared service in the secondary job scripts to be replaced with mock service calls. The secondary job scripts are then scheduled and executed, and upon completion the primary job script is permitted to delete the shared service.Type: GrantFiled: April 28, 2022Date of Patent: June 20, 2023Assignee: SAP SEInventors: Long Du, Le Zhang, Yu Wang
