A method of operating an exoskeleton device includes: receiving sensor information; connecting a clutch system to a pulley system in; determining whether to engage a drive train gear to the clutch system based on the sensor information; engaging the drive train gear through the clutch system when determined to engage the drive train gear; and powering a first motor to drive the drive train gear for controlling a joint or segment of exoskeleton device.

An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's goggles.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

The present disclosure is directed to a system for sensor-based objective determination. An example apparatus includes memory, instructions, and processor circuitry to execute the instructions to at least compare time-synchronization data between a first signal and a second signal, the first and second signals received in response to a detected contact between a first participant and a second participant in an event, wherein the first signal is received from a first sensor operably coupled to the first participant, the first sensor to measure at least one first physical parameter of the first participant while the first participant is engaged in the event, and wherein the second signal is received from a second sensor operably coupled to the second participant, the second sensor to measure at least one second physical parameter of the second participant while the second participant is engaged in the event, and determine, based on (a) the time-synchronization data, (b) the at least one first physical parameter, and (c) the at least one second physical parameter, whether the detected contact between the first participant and the second participant exceeds one or more thresholds corresponding to a rules-based infraction associated with the event.

An apparatus comprising a practice device for practice of hitting a tennis ball includes a server configured for serving the tennis ball to a user, a net disposed to intercept a flight of the tennis ball after the tennis bell has been hit by the user using a racket and to direct the captured tennis ball back towards the server to be served again to the user, an image detector configured to observe the tennis ball as the tennis ball hurtles towards the net, and a processor. The processor determines, based at least in part on image frames received from the image detector, data indicative of the tennis ball's virtual landing spot. This virtual landing spot is an estimate of where the tennis ball would have landed on an opposing court had the tennis ball not been intercepted by the net.

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.

Embodiments disclosed herein relate to a garment system including at least one sensor and at least one actuator that operates responsive to sensing feedback from the at least one sensor to cause a flexible compression garment to selectively constrict or selectively dilate, thereby compressing or relieving compression against at least one body part of a subject. Such selective constriction or dilation can improve muscle functioning or joint functioning during use of motion-conducive equipment, such as an exercise bike or rowing machine.

Provided is an apparatus for managing a player with a guard including a sensor sensing a vital information of a player to calculate an injury risk of the player to thereby manage a condition of the player, the apparatus including: a communication unit receiving the vital information from the guard and transmitting the injury risk to the guard; a memory storing a program calculating the injury risk to manage the condition of the player; and a processor connected to the communication unit and the memory to execute an operation implemented by the program, in which the program may include instructions using the vital information and pre-stored vital recovering ability data of the player to calculate the injury risk of the player.

Systems and methods are for production, management, syndication and distribution of exercise class content for use with an exercise apparatus. An exercise content distribution system includes a database storing the exercise content and data associated with a content provider and an application provider, and a platform server operable to facilitate delivery of the exercise content to the exercise apparatus. The platform server is configured to deliver archived exercise classes, receive a selection of one of the archived exercise classes, transmit data representing content of the selected archived exercise class, receive performance data based on activity by the first user, generate archived performance data for a plurality of other users, and dynamically update a ranked list and at least some of the synchronized archived user performance parameters for display by the exercise apparatus. Subscription channels can support diversely curated and priced exercise class offerings, including acceptance of crypto-currency.
