Publication number: 20240141929Abstract: This invention discloses a pneumatic and cable-driven hybrid artificial muscle, comprising pneumatic actuator, pneumatic pressure regulating assembly, and cable drive assembly. The pneumatic pressure regulating assembly is connected to the pneumatic actuator to regulate air pressure in the pneumatic actuator for controlling the pneumatic actuator to extend or contract. The cable actuation assembly comprises a cable fixedly connected to the pneumatic actuator for controlling the pneumatic actuator to contract. In this invention, the artificial muscle employs a dual pneumatic and cable actuation mechanism. By leveraging the inherent stiffness of the pneumatic actuator, it can provide substantial actuation force for joint movement. Simultaneously, the cable actuation assembly can provide significant pulling force, effectively ensuring safety in human-machine interaction and offering sufficient bidirectional aiding force to individuals with disabilities who use the artificial muscle as an aiding actuation device.Type: ApplicationFiled: October 4, 2023Publication date: May 2, 2024Inventors: Yong HU, Xiao Dong LI, De Hao DUAN MU, Xiao Jun WANG, Xiang CAO

Patent number: 11954524Abstract: A method for scheduling services in a computing environment includes receiving a service scheduling request corresponding to the computing environment and identifying a resource pool and a set of compliance requirements corresponding to the computing environment. The method continues by identifying target resources within the resource pool, wherein target resources are resources which meet the set of compliance requirements, and subsequently identifying a set of available target resources, wherein available target resources are target resources with scheduling availability. The method further includes analyzing the set of available target resources to determine a risk score for each available target resource and selecting one or more of the set of available target resources according to the determined risk scores. The method continues by scheduling a service corresponding to the service scheduling request on the selected one or more available target resources.Type: GrantFiled: May 26, 2021Date of Patent: April 9, 2024Assignee: International Business Machines CorporationInventors: Braulio Gabriel Dumba, Jun Duan, Nerla Jean-Louis, Muhammed Fatih Bulut, Sai Zeng

Publication number: 20240098008Abstract: An anomalous behavior detector has been designed to detect novel behavioral changes of devices based on network traffic data that likely correlate to anomalous behaviors. The anomalous behavior detector uses the local outlier factor (LOF) algorithm with novelty detection. After initial semi-supervised training with a single class training dataset representing stable device behaviors, the obtained model continues learning frontiers that delimit subspaces of inlier observations with live network traffic data. Instead of traffic variables being used as features, the features that form feature vectors are similarities of network traffic variable values across time intervals. A feature vector for the anomalous behavior detector represents stability or similarity of network traffic variables that have been chosen as device identifiers and behavioral indicators.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Ke Tian, Yilin Zhao, Xiaoyi Duan, Jun Du

Patent number: 11930073Abstract: A computer-implemented method, system and computer program product for maximizing system scalability while guaranteeing enforcement of service level objectives. A request is received to access a backend database in a hierarchy of backend databases that includes heterogenous computing resources with a dynamic range of performance. Upon receiving the request, a reinforcement learning based filter determines if the request's frequency of access exceeds a cutoff frequency. If the received request is not filtered, but instead, is passed through the filter, then one of the backend databases in the hierarchy is selected. Such a selection is made by a load balancer that is trained using reinforcement learning to select the optimal backend database taking into consideration the storage size and speed of the backend databases as well as taking into consideration the user-specified service level objective to be met by the request to guarantee enforcement of such a service level objective.Type: GrantFiled: October 21, 2022Date of Patent: March 12, 2024Assignee: International Business Machines CorporationInventors: Jun Duan, Braulio Gabriel Dumba, Andrew John Anderson
