Publication number: 20190041220Abstract: A three-dimensional (3D) geolocation system for providing the 3D coordinates of a moving person in the absence of a Global Positioning System (GPS) signal. The 3D geolocation system uses two inertial sensors configured to be positioned at the left and right foot-ankle structure and a series of sensors to measure the spatial orientation of each segment of the lower limbs (shanks, thighs, trunk) of the user. In one example, the 3D geolocation system uses two additional inertial sensors at the left and right leg-knee or thigh-hip structure as well as sensors providing information indicative of the angular positions of the left and right knee and thigh, which may be provided by an exoskeleton or orthotic devices worn by the user. This determination of the 3D coordinates of the user is performed using biomechanics information about the user from the inertial sensors combined with the knee and hip angles.Type: ApplicationFiled: January 25, 2017Publication date: February 7, 2019Inventors: Nathaniel ZOSO, Victorien THIAUX, Éric DUPLAIN, Martin BEAUMONT, Stéphane BÉDARD

Patent number: 9649206Abstract: A motorized prosthetic device includes a joint member, a limb member, a pressure sensor, and a kinematic sensor. The pressure sensor indicates interaction between the motorized prosthetic device and the ground and the kinematic sensor measures torque at the joint member. A controller receives data from the pressure sensor and kinematic sensor and calculates a control signal based at least on the received data. An electrical motor receives the control signal and operates an actuator in accordance with the received control signal.Type: GrantFiled: July 17, 2013Date of Patent: May 16, 2017Assignee: Victhom Laboratory Inc.Inventor: Stéphane Bédard

Patent number: 9370439Abstract: A load distribution device that transfers the musculo-skeletal stress at a joint to associated body segments of a given joint-segments body structure. The device includes a proximal support element adapted to be positioned onto a proximal body segment, a distal support element adapted to be positioned onto a distal body segment, a compensating joint movably connecting the proximal and distal support elements, a control system operatively connected to the compensating joint and a power source supplying power to the control system and the compensating joint. During user executed movements, the compensating joint generates or dissipates, under the directions of the control system a preset level of biomechanical energy corresponding to a user desired musculo-skeletal stress reduction at the joint-segments structure in order to compensate the movements of the user, the biomechanical energy being redistributed onto the proximal and distal body segments via the corresponding proximal and distal support elements.Type: GrantFiled: February 18, 2011Date of Patent: June 21, 2016Inventors: Stéphane Bédard, Dany Lachance, Benoit Gilbert, Yves Roy
