Systems and methods for tracking a sports ball assembly in real time during a sporting event are disclosed. A structure of the sports ball assembly is also disclosed. The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the processor with time stamps. The processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

A system, method, and wireless earpieces for implementing a virtual assistant. A request is received from a user to be implemented by wireless earpieces. A virtual assistant is executed on the wireless earpieces. An action is implemented to fulfill the request utilizing the virtual assistant. The wireless earpieces may be a set of wireless earpieces and the virtual assistant may be implemented independently by the wireless earpieces.

A ground traversing, electrically driven drone travels along a programmed path that corresponds to pass catcher's travel path during a play, matching the pass catcher's speed and run cuts. The play is wirelessly communicated to the drone by a handheld electronic device located remote of the drone. A target is located on the drone so that a quarterback can throw a football at the target in order to refine the quarterback's timing and accuracy for the play. Sensors located remote of the drone track both the football's and quarterback's speed and travel trajectories so that such data can be collected, along with the drone's travel path, and transmitted to the computer and eventually fed into 3-D reconstruction software for analysis by the quarterback and coaching staff. The target rotates so that the target either faces in a fixed direction or constantly faces the quarterback during execution of drone's maneuvers.

Embodiments of the present invention comprise a 4-wheeled resistance training device in the form of a box, wherein a user may add weights to the inside or to the top of the box to increase the resistance provided to the user. The wheels may be connected to the box by one or more threaded axles, each threaded axle existing as two or more parts. Rotation of the threaded axles may power a generator, which may power a light system comprising one or more lights. The light system may provide visual feedback to a user by changing the color and/or intensity of the one or more lights depending on multiple factors. Further embodiments of the invention may comprise a battery for storing energy generated by the generator. Embodiments of the invention may also comprise the ability to store data about a user's workout.

A treadmill according to the present invention includes: a frame; an endless belt; an endless-belt drive unit; a plurality of cameras provided on the frame such that the orientations and/or locations thereof can be adjusted; a motion-data acquisition unit that markerlessly acquires motion data of a subject by using image information obtained with camera images; a motion analysis unit that analyzes the motion of the subject by using the motion data; and a control unit that controls the endless-belt drive unit based on the motion data.

In particular embodiments, a treadmill may comprise one or more lifting mechanisms configured to lift and lower a treadmill belt (e.g., adjust an angle of the treadmill belt relative to a support surface) by adjusting a height of the front and rear of the treadmill about a pivot point. In particular embodiments, the pivot point may be positioned somewhat centered along a length of the belt. In particular embodiments, a seesaw arrangement may provide a central pivot point, providing a moment arm to the motor while decreasing a moment arm caused by the load (e.g., a runner). In this way, an apparent load on a motor providing incline and decline to the running surface may be reduced.

A method determines running phases of a user on a treadmill having first and second rotating elements rotating about respective rotational axes transverse to a longitudinal axis of the treadmill. A physical exercise surface connects to the rotating elements. An electric motor operatively associated with one rotating element rotates the rotating elements and the physical exercise surface. A processor connects to the electric motor and controls the electric motor. The processor determines a magnitude variable over time, which is correlated to user interaction with the exercise surface while exercising and has a periodic trend. The processor determines time instants of at least two points of the periodic trend. The time instants of each point representing instants of user interaction with the exercise surface. The processor determines a running phase of the user on the exercise surface as a function of the respective time instants of the periodic trend.

An electronic device and method for detection of intentional contact between an object and a body part of a player are provided. An electronic device receives a plurality of frames of a video from an imaging device. The electronic device tracks a movement of the object and a movement of the body part across the plurality of frames. The electronic device determines, based on the tracked movement, a frame of interest from the plurality of first frames in which degree of overlap between position coordinates of the object and position coordinates of the body part of the player exceeds an overlap threshold. The electronic device detects a contact between the object and the body part of the player based on the frame of interest. The electronic device applies a machine learning model on the frame of interest and the tracked movement to determine whether the contact is intentional.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive a physiological measure. The processor is further configured to display, via the display system, the physiological measure, wherein the display system is disposed in the eyewear so that the physiological measure is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.
