Patent number: 11826612Abstract: A portable instrument provided with a device for controlling or managing a sports or well-being activity of a person wearing the portable instrument. The control device includes at least a motion sensor and a pressure sensor connected to a calculation unit, and a GNSS receiver module connected to the calculation unit.

Patent number: 11540748Abstract: A method of detecting gaits of an individual with a sensor worn by the individual. The sensor includes an accelerometer and a processing unit. The method includes obtaining an signal representing one or more sensor acceleration values; sampling the signal to obtain a sampled signal; segmenting the sampled signal into windows to obtain a segmented acceleration signal; extracting a feature set from the segmented acceleration signal; determining a probability value, for a respective window, n, where n is a positive integer greater than zero, the probability value giving an estimated probability value of gait occurrence for the individual during the respective window; modifying the estimated probability value by using a histogram of previously detected gait durations to obtain a modified probability value; and determining, based on the modified probability value, and by using a determination threshold whether or not the respective window represents gait occurrence.Type: GrantFiled: June 19, 2020Date of Patent: January 3, 2023Assignee: The Swatch Group Research and Development LtdInventors: Cedric Nicolas, Abolfazl Soltani, Hooman Dejnabadi, Martin Savary, Kamiar Aminian

Publication number: 20180292429Abstract: A method for contactlessly determining an exact passage of an athlete at points placed along a track in sports, wherein the method comprises gearing the athlete with a wearable magnetometer sensor unit, whereby the magnetometer sensor unit is equipped with at least a magnetic sensor, a processing unit, and a storage medium; placing at each point at least a permanent magnet in proximity of a track surface of the track. When the athlete moves along the track, the method further comprises recording at the magnetic sensor a signal; detecting for each permanent magnet a disturbance of a local magnetic field generated by the permanent magnet in the recorded signal and measuring the disturbance; mapping of the measured disturbance to a movement speed of the athlete and a distance of the athlete to the magnet corresponding to the local magnetic field; and correcting the movement speed and the distance for a time offset between the magnet passage of an athlete's center of mass and the magnetometer sensor unit.Type: ApplicationFiled: April 28, 2016Publication date: October 11, 2018Inventors: Benedikt Fasel, Kamiar Aminian

Patent number: 9307932Abstract: The invention relates to a system and a method for assessment of walking and miming gait in human. The method is preferably based on the fusion of a portable device featuring inertial sensors and several new dedicated signal processing algorithms: the detection of specific temporal events and parameters, 5 optimized fusion and de-drifted integration of inertial signals, automatic and online virtual alignment of sensors module, 3D foot kinematics estimation, a kinematic model for automatic online heel and toe position estimation, and finally the extraction of relevant and clinically meaning-full outcome parameters. Advantageously including at least one wireless inertial module attached to foot, the system provides common spatio-temporal parameters (gait cycle time, stride length, and stride velocity), with the 10 advantage of being able to work in unconstrained condition such as during turning or running.Type: GrantFiled: May 25, 2011Date of Patent: April 12, 2016Assignee: Ecole Polytechnique Federale de Lausanne (EPFL)Inventors: Benoît Mariani, Kamiar Aminian

Patent number: 9092071Abstract: A control device includes a two-dimensional inertial system configured to measure an acceleration of the control device. A control circuit is coupled to the two-dimensional inertial system where the control circuit is configured to receive acceleration information for the acceleration measured by the two-dimensional inertial system. The control circuit is further configured to integrate the acceleration information to calculate the velocity of the control device and determine if the velocity of the control device becomes zero along one or both of the two dimensions for which the two-dimensional inertial system is configured to measure acceleration. The control circuit is further configured to correct a drift in the velocity if the control circuit determines that the velocity is zero along one or both of the two dimensions.Type: GrantFiled: May 13, 2011Date of Patent: July 28, 2015Assignee: Logitech Europe S.A.Inventors: Hooman Dejnabadi, Kamiar Aminian, Nicolas Chauvin
