Patent number: 11788562Abstract: The subject invention pertains to a pneumatic, hydraulic, or otherwise inflatable or pressurized artificial muscle. Also provided are methods for making, controlling, and using such a muscle useful for prostheses, movement aids, or wearable robots to assist the movement of impaired subjects or to improve the function of healthy subjects. Muscles can be made by densely winding tension wires around pressurized expandable tubes having one or more specific geometric shapes removed from the tube cross section. The curve of output characteristics such as output force vs. contraction ratio can be adjustable by changing parameters of the sectional view of the tube. The appropriate shape of tube and related output characteristics can be selected according to application area or body part to be assisted to achieve the most flexible and optimal design for one or more muscle groups.Type: GrantFiled: May 19, 2022Date of Patent: October 17, 2023Assignee: The Chinese University of Hong KongInventors: Kai Yu Tong, Disheng Xie, Jing Shu, Junming Wang

Patent number: 9031631Abstract: A head-mountable EEG electrode-containing device is provided based on radially adjustable electrodes to fit the wearer's unique head size and shape. The head-mountable device with an electrode array positioned therein includes multiple head-mountable device sections that are interconnected by mechanical fasteners to facilitate sizing and positioning of the head-mountable device. An array of resilient sleeves is positioned within each head-mountable device section. Each resilient sleeve houses an individual electrode and is deformable for self-orienting. The deformation of the sleeve is such that a central axis passing through the individual electrode housed within the resilient sleeve is maintained in a position approximately normal to a plane tangential to a scalp portion positioned beneath that electrode.Type: GrantFiled: January 31, 2013Date of Patent: May 12, 2015Assignee: The Hong Kong Polytechnic UniversityInventors: Kai Yu Tong, Bun Yu, Peter Man Kit Pang, Newmen Sze Kit Ho, Xiaoling Hu, Robert Wai Man Tam, Shu To Ng
