Patent number: 11048775Abstract: A method is provided for the automatic control of cycling speed in a human. The method comprises: estimating the subject's actual cycling speed using one or more sensors to thereby obtain a measured speed; determining an error comprising a difference between a desired speed and the measured speed; and outputting, to the subject, a stimulus frequency signal wherein the stimulus frequency signal is based on the error in such a manner that when the subject pedals in a manner that matches a frequency of the stimulus frequency signal, the subject's actual speed controllably tracks the desired speed.Type: GrantFiled: March 8, 2019Date of Patent: June 29, 2021Assignee: Simon Fraser UniversityInventors: Mark Snaterse, James Maxwell Donelan, Sung Jae Chang

Patent number: 10289753Abstract: A method is provided for guiding locomotion speed in a human or other animal subject. The method comprises: estimating the subject's actual locomotion speed using one or more sensors to thereby obtain a measured speed; determining an error comprising a difference between a desired speed and the measured speed; and outputting, to the subject, a stimulus frequency signal wherein the stimulus frequency signal is based on the error in such a manner that when the subject ambulates in a manner that matches a frequency of the stimulus frequency signal, the subject's actual speed controllably tracks the desired speed.Type: GrantFiled: July 7, 2011Date of Patent: May 14, 2019Assignee: Simon Fraser UniversityInventors: Mark Snaterse, Sung Jae Chang, James Maxwell Donelan

Patent number: 9057361Abstract: Methods and apparatus are disclosed for harvesting energy from motion of one or more joints. Energy harvesters comprise: a generator for converting mechanical energy into corresponding electrical energy; one or more sensors for sensing one or more corresponding characteristics associated with motion of the one or more joints; and control circuitry connected to receive the one or more sensed characteristics and configured to assess, based at least in part on the one or more sensed characteristics, whether motion of the one or more joints is associated with mutualistic conditions or non-mutualistic conditions. If conditions are determined to be mutualistic, energy harvesting is engaged. If conditions are determined to be non-mutualistic, energy harvesting is disengaged.Type: GrantFiled: June 27, 2013Date of Patent: June 16, 2015Assignee: Bionic Power Inc.Inventors: James Maxwell Donelan, Arthur D. Kuo, Joaquin Andres Hoffer, Qingguo Li, Douglas Weber
