A method monitors cardiac arrest during physical exercise and consequently activates a rescue request. The method continuously measures a user's heart rate to determine a heart rate in a sequence of predetermined time intervals, by a heart rate measurement device worn by the user; then, generating a signal representative of the heart rate detected in each interval. A motion sensor detects a user's motion condition and generates a motion signal representative of the motion detected. A portable processor receives the heart rate signal and communicates with the heart rate measurement device and with the motion sensor; then processes the signal representative of heart rate, to recognize a possible cardiac arrest condition. The processor processes the motion signal to detect a possible stillness condition. The processor activates a rescue request if both a cardiac arrest condition and a stillness condition have been recognized. A system executes the method.

A trampoline as a controller or an input device for playing games, including a frame having a flexible mat divided into input zones and one or more neutral zones, a sensor arrangement to detect activity on the flexible mat, a controller configured to determine the bounce location and bounce zone of the activity and provide this information to a feedback generator for playing games on the trampoline, such that a user uses the trampoline to play games by jumping on the input and neutral zones.

Various examples are provided for intelligent mouthguards that can be used in fitness and sport activities. In one example, an intelligent mouthguard system includes a mouthguard including sensors and an internal module in communication with the sensors. The sensors can include a nine-axis inertial sensor comprising a three-axis magnetometer, a three-axis accelerometer and a three-axis gyroscope. The three-axis magnetometer can provide a reference plane in relation to the earth's magnetic field for the three-axis accelerometer and the three-axis gyroscope. The internal module can provide sensor data to an external processing unit when located in an oral cavity.

A system and method for recording and broadcasting motion of a sports ball and individual players includes a sports ball with cameras embedded within for recording trajectory and locomotion, a sensor module for storing video footage and telemetry metadata, and cameras mounted on the sports equipment of individual players. The sensor module includes an Inertia Measuring Unit, a transceiver, a memory, a power source, and a processor, all operatively connected to one another. The sports ball sends data to a wireless data transmission grid mounted under a sports pitch and/or to antennas for transfer to a data processing server which determines a real ball direction thereafter sent to a stadium camera system that generates further 360 degree action-focused broadcasting data. The data is sent to the processing server which processes the raw footage received from the sports ball and individual players to produce clean footage for various applications.

A system and method wherein ball spin rate and axis orientation are determined according to an electronic circuit that includes a magnetometer spin sensor module and, in the alternative, an electronic circuit that includes a spin sensor module with a plurality of accelerometers.

An exercise device includes a base defining an inner volume and a top supported by the base, the top defining an aperture. The exercise device further includes a force sensor configured to measure force on the top and a motor disposed within the base and below the top, the motor including a cable extendable through the aperture. The exercise device further includes a controller communicatively coupled to each of the force sensor and the motor. The controller is adapted to actuate the motor in response to forces applied to the top as measured by the force sensor. The controller may also actuate the motor in response to one or more additional parameters related to the speed or force with which the cable is manipulated (e.g., pulled by a user).

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 torque measuring device for a flywheel is mounted on a frame of an exercise bike and has a base, multiple torque measuring apparatuses of a measuring assembly mounted on the base, a communication module mounted on the base, and a power module mounted on the base. The base is directly connected to the flywheel, a Wheel shaft, and a transmission mechanism of the exercise bike. The communication module receives and outputs measurement data. The power module provides electricity to the communication module and the measuring assembly. Through the simplified structure, the torque measuring device is directly assembled on the exercise bike to improve installation convenience and facilitate inspection or replacement. Moreover, the multiple torque measuring apparatuses can rotate simultaneously along with the base so as to improve the accuracy of torque measurement.

A stretching device comprising an elongated band having a first end and a second end, a first handle coupled to the band proximate the first end, a second handle coupled to the band proximate the second end, and a boot coupled to the band between the first end and the second end, the boot adapted to engage with a body part of a person, horse, or other animal.

A golf ball with embedded electronics to allow proximity to be tracked and to monitor golfer performance is disclosed. The golf ball comprises a processor connected to an accelerometer, communications circuitry, a spin detector, and memory, wherein the processor stores accelerometer data from the accelerometer and rotation data regarding rotation of the spin detector in the memory. The processor converts the data regarding the rotation of the spin detector into a rotation speed and a rotation direction, said rotation speed determined by a frequency of the data, and said rotation direction determined by a magnitude of the data. The communications circuitry is configured to communicate the accelerometer data, the rotation direction, and the rotation speed to a central interrogator for analysis of a golfer's performance.
