Patent number: 10973620Abstract: In a biomimetic artificial muscle module, a biomimetic artificial muscle assembly having the biomimetic artificial muscle module, and a method of controlling the biomimetic artificial muscle module, the biomimetic artificial muscle module includes an operating part, an elastic part, a driving part, a locking part and first and second sensors. The operating part contracts or relaxes along a longitudinal direction. The elastic part is connected to a first end of the operating part, and behaves elastically behave according to an external force. The driving part is connected to a second end of the operating part, and drives the operating part to be contracted or relaxed. The locking part selectively blocks a length of the operating part from being changed. The first and second sensors respectively sense the elastic part and the operating part.Type: GrantFiled: January 31, 2019Date of Patent: April 13, 2021Assignee: KOREA INSTITUTE OF MACHINERY & MATERIALSInventors: Sang-Kyu Choi, Hyun Joon Kwon, Jae Keun Shim, Young-Su Son, Cheol-hoon Park, Seyoung Kim

Patent number: 8156823Abstract: A 6-axis force sensor includes bumper 10 with bumper axis 12 and press member 11 which has four horizontal beams 11a, 11b, 11c and 11d in a cross shape with end, side and bottom faces. Sensors 31, 32, 33, and 34 on end faces sense force in one direction and sense a moment acting on opposite end faces. Sensors 41, 42, 43, and 44 on side faces sense force in a second direction transverse to the first direction and sense a moment acting on opposite side faces. A film 20 on the bottom faces has four sensors 21, 22, 23, and 24, one on each bottom face, for sensing force in a direction transverse to the first and the second directions and sensing a moment acting on opposite sensors on the film.Type: GrantFiled: December 31, 2009Date of Patent: April 17, 2012Assignee: Korea Research Institute of Standards and ScienceInventors: Jong Ho Kim, Hyun Joon Kwon, Dong-ki Kim

Publication number: 20100149124Abstract: A method for implementing a mouse algorithm using a plurality of pressure sensors is disclosed. The pressure sensors are used to freely move and rotate a mouse cursor in X, Y and Z directions, so that they can be applied as interface units for a slim device such as a mobile phone. The mouse algorithm processes a touch input. The pressure sensors are arranged in a ring shape and provide output values successively varying with magnitudes of forces applied thereto or pressures applied thereto. A moving direction of the mouse cursor is determined depending on a contact point detected through the output values and a moving distance and moving speed of the mouse cursor are determined in proportion to the magnitudes of the forces.Type: ApplicationFiled: August 3, 2007Publication date: June 17, 2010Applicant: KOREA RESEARCH INSTITUTE OF STANDARDS AND SCIENCEInventors: Jong-ho Kim, Hyun-joon Kwon, Yon-kyu Park, Min-seok Kim, Dae-im Kang, Jae-hyuk Choi
