Patent number: 11806119Abstract: An electronic fitness device includes a housing, a first optical transmitter array, a first optical receiver, and a second optical receiver. The first optical transmitter array is positioned at a first location on a bottom wall and may output a plurality of optical signals that pass through a user's skin. The first optical receiver is positioned at a second location and may receive the optical signals from the first optical transmitter array such that the optical signals travel along a first signal path and a first distance. The second optical receiver is positioned at a third location and may receive the optical signals from the first optical transmitter array such that the optical signals travel along a second signal path and a second distance, wherein the second signal path is roughly orthogonal to the first signal path and the second distance is different from the first distance.Type: GrantFiled: March 16, 2020Date of Patent: November 7, 2023Inventors: Simon LeFrancois, Paul R. MacDonald, Kristin A. Stevens

Patent number: 11573140Abstract: This invention relates to force/torque sensor and more particularly to multi-axis force/torque sensor and the methods of use for directly teaching a task to a mechatronic manipulator. The force/torque sensor has a casing, an outer frame forming part of or connected to the casing, an inner frame forming part of or connected to the casing, a compliant member connecting the outer frame to the inner frame, and one or more measurement elements mounted in the casing for measuring compliance of the compliant member when a force or torque is applied between the outer frame and the inner frame.Type: GrantFiled: November 10, 2020Date of Patent: February 7, 2023Inventors: Nicolas Lauzier, Simon Lefrançois, David Castonguay, Louis-Alexis Allen Demers, Jean-François Duval, Yan Drolet Mihelic, Pierre Olivier Proulx, Rachid Bekhti, Philippe Cardou, Vincent Duchaine, Samuel Bouchard, Jean-Philippe Jobin
