Patent number: 11574149Abstract: A system and method are provided that use context awareness with device-dependent training to improve precision while reducing classification latency and the need for additional computing, such as by relying on cloud-based processing. Moreover, the following can leverage signal analysis with multiple sensors and secondary validation in a multi-modal approach to track passive events that would otherwise be difficult to identify using classical methods. In at least one implementation, the system and method described herein can leverage low power sensors and integrate already available human behavior in modular algorithms isolating specific context to reduce user interact time and training to a minimum.Type: GrantFiled: November 14, 2018Date of Patent: February 7, 2023Assignee: CONTXTFUL TECHNOLOGIES INC.Inventors: Alexandre Desilets-Benoit, Bruno Falardeau, Raymond Poitras, Maria Virginia Ruiz-Blondet, Felix Leger

Publication number: 20220387111Abstract: A computer-assisted surgery system for obtaining a distance between at least two fixed points relative to a bone comprises a first accelerometer unit located at a first fixed location on the bone, and producing first acceleration data during a movement of the bone. A second accelerometer unit is located at a second fixed location on the bone, and simultaneously producing second acceleration data during the movement. A gyroscope unit is fixed to the bone and simultaneously producing angular rates of change of said movement. A processor unit obtains the acceleration data and the angular rates of change for calculating the distance between the first fixed position and the second fixed position on the bone using a distance value of a distance vector between the accelerometer units. An interface outputs the distance between the first fixed position and the second fixed position relative to the bone. A method for calculating a distance between at least two points on a bone is provided.Type: ApplicationFiled: August 17, 2022Publication date: December 8, 2022Inventors: Bruno FALARDEAU, Catherine PROULX, Herbert Andre JANSEN, Benoit PELLETIER, Jonathan TARDIF
