Patent number: 10959863Abstract: The present invention discloses a multi-dimensional surface electromyogram signal prosthetic hand control method based on principal component analysis. The method comprises the following steps. Wear an armlet provided with a 24-channel array electromyography sensor to a front arm of a subject, and respectively wear five finger joint attitude sensors at a distal phalanx of a thumb and at middle phalanxes of remaining fingers of the subject. Perform independent bending and stretching training on the five fingers of the subject, and meanwhile, collect data of an array electromyography sensor and data of the finger joint attitude sensors. Decouple the data of the array electromyography sensor by principal component analysis to form a finger motion training set. Perform data fitting on the finger motion training set by a neural network method, and construct a finger continuous motion prediction model. Predict a current bending angle of the finger through the finger continuous motion model.Type: GrantFiled: May 23, 2018Date of Patent: March 30, 2021Assignee: SOUTHEAST UNIVERSITYInventors: Aiguo Song, Xuhui Hu, Hong Zeng, Baoguo Xu, Huijun Li

Patent number: 7961710Abstract: A method and apparatus is provided for setting multiple paths between wireless nodes of an ad-hoc network including a source node, a relay node and a destination node that receives a message from the source node via the relay node. The multi-path setting method and apparatus includes receiving previous hop address information, and determining whether a wireless node that receives the previous hop address information is included in an insulating region, based on the previous hop address information.Type: GrantFiled: February 13, 2007Date of Patent: June 14, 2011Assignees: Samsung Electronics Co., Ltd., The Research Foundation of the City University of New YorkInventors: Ji-Hoon Lee, Xuhui Hu, Yong Liu, Myung-Jong Lee

Patent number: 7564842Abstract: The disclosure is a routing method for data in a personal area network. The personal area network includes a plurality of nodes. The method includes receiving a frame at a node, determining whether the node contains a routing table entry for the frame destination, and when the node contains a routing table entry, determining a route for the frame based on a first routing protocol. The method further includes, when the node does not contain a routing table entry for the frame destination, determining whether a route should be discovered for the frame destination, and when a route should not be discovered, determining a route for the frame based on a second routing protocol.Type: GrantFiled: July 1, 2004Date of Patent: July 21, 2009Assignees: Mitsubishi Electric Research Laboratories, Inc., Samsung Electronics Co. Ltd., Intel Corporation, NXP B.V., Motorola, Inc.Inventors: Edgar Herbert Callaway, Jr., Lance Eric Hester, Vernon Anthony Allen, Jasmeet Chhabra, Lakshman Krishnamurthy, Ralph M.

Patent number: 7450521Abstract: A routing method comprising receiving a first packet, the first packet being broadcast for discovery of a route. A first backoff of the first packet is calculated based on a route cost of the first packet. The first packet is rebroadcast if a second packet is not received within the first backoff, the second packet being a duplicate of the first packet. A second backoff of the second packet is calculated based on a route cost of the second packet if the second packet is received within the first backoff. One of the first and the second packets is rebroadcast as a result of comparing the first backoff and the second backoff.Type: GrantFiled: February 11, 2005Date of Patent: November 11, 2008Assignees: Samsung Electronics Co., Ltd., City University of New YorkInventors: Jong-hun Park, Myung-jong Lee, Yong Liu, Xuhui Hu
