Motion sickness is reduced for users of mechanical systems used to practice sports that comprise an immersive virtual reality device. In particular, the use of prediction and interpolation algorithms enable fluid movements to be displayed within the virtual environment.

For the method and system (1) for measuring physical parameters, several motion sensor assemblies (2) are arranged in different positions on a trampoline (10) and activated to measure any motion over time during jumps performed by a competitor on a trampoline. Following the processing of measurements made in each sensor assembly, data signals are transmitted to a base station (25). As a result of the various measurements received over time from each sensor assembly, the base station determines a time of flight for each of the competitor's jumps, and a position of contact of the competitor on the bed (21) to award points to the competitor for the performance of a determined number of jumps during the competition.

A method for determining biomechanical parameters of the stride of a runner, using an accelerometer device on the wrist, on the upper arm, on the head or on the shoe, comprising the steps of measuring an initial sequence of acceleration data in at least the vertical direction using said accelerometer device; identifying in said initial sequence of acceleration data at least one frequency component caused by relative motion of the accelerometer device relative to the runner center of masse; attenuating said frequency component, so as to determine a modified sequence of acceleration data; determining said biomechanical parameters from said modified sequence of acceleration data.

Technologies are disclosed herein for one or more sensors arrayed adjacent to a golf course playing surface to track the trajectory and determine a resting location of a golf ball it travels along the golf course playing surface. The sensors may include motion detecting sensors that may determine various measurements related to the location and/or movement of the golf ball, such as an initial impact location, a velocity, and/or a direction of travel of the golf ball along the golf course playing surface. The signals from the motion detecting sensors may further be used to determine a resting location for the golf ball and/or a rate of acceleration/deceleration of the golf ball. The various signals may be averaged together to determine a velocity and/or direction of travel of the golf ball.

The present invention relates to a multi-gym machine which enables a user to perform a plurality of different exercises for the whole body. More specifically the present invention relates specifically to a power tower machine in which the user utilizes a combination of the user body weight (calisthenics) in addition to variable elastic bands to provide additional assistance or resistance. This advanced power tower hereby disclosed incorporates an arrangement of multiple handles, various pulleys, elastic cables and steel wire connected to a special waist belt to be put on by the user. The elastic cables depending on their anchor points either from the top or the bottom pulley, generates assistance or resistance to the user respectively for the specific workout. A set of sensors, processor and Bluetooth transmission unit is integrated on the power tower to process, transmit, process and manage several workouts performance indicators via a dedicated mobile application offering a virtual coaching capabilities. Also with internet connection, the mobile application offers an IoT (Internet of Things) concept enable virtual competition with other users using the same machine and mobile application.

Systems and methods are provided for enabling a split belt treadmill having two belts to self-pace. A feedback process estimates a first current step speed for a user on each belt by measuring stride length and step duration. A feed-forward process estimates a second current step speed for the user on each belt by measuring three forces and three moment components associated with foot contact with the belt. A command speed for each belt is produced by combining the first and second current step speeds with a Kalman filter. A belt speed associated with each belt is adjusted based upon the command speed.

Aspects of the present disclosure generally pertain to a piata interaction device, system, and method. Aspects of the present disclosure more specifically are directed toward an electronic device for a piata that includes a housing, a power supply, a speaker, an impact sensor, an user interface, and a controller module configured to store a plurality of piata communications to emit at least one of the plurality of piata communications in response to the piata being hit. The electronic device is removably coupleable with at least one of the piata and the hitting stick. The electronic device may be reconfigured to output customized responses or from a wide library of audio is stored which can be selected from music, voice, instructions or sounds of various kinds. The electronic device may interact with third party devices via hosted application.

A fitness-training device; the fitness-training device is embedded within a graspable handle of an exercise apparatus and may include a heart rate detector, a repetitive motion counter, and indicators to indicate the heart rate, and repetitive motion count during an exercise activity. The fitness-training device may be incorporated in a wide range of sports and exercise equipment. A version of the fitness-training device arranged as a jump rope is disclosed herein.

A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

A system and method for range of motion analysis while exercising, including methods for constructing user movement profiles based on repeated and typical user movements during exercises as are typical for an adult of a user's age, weight, etc., and capable of warning a user of unhealthy, unsafe, or anomalous movement patterns during exercise, using a balance trainer, range of motion analyzer, and a plurality of sensors in conjunction with an exercise device, in an effort to reduce health risks to users during exercise with an enhanced or mixed reality exercise device.
