A training, rehabilitation, and recovery system comprises an exercise apparatus including a user interface member coupled to a plurality of links and joints, brakes capable of resisting movement of at least a subset of the links or joints, and sensors capable of sensing movement at the joints or the user interface member. The system also includes a processor configured to receive from the sensors positional data of the links or joints over an initial movement of the apparatus by a user, from which positional coordinates of the user interface member are calculated and a reference trajectory is established. An end space is defined based on the reference trajectory. Over a subsequent movement of the apparatus by the user, the processor receives additional positional data and determines a completion of a repetition based on the positional coordinates of the subsequent movement and the defined end space.

A luminous ball is provided, including a sphere, at least one covering spliced to wrap the sphere, at least one seam formed on an edge of the covering, a plurality of thread apertures disposed at two sides of the seam, at least one thread penetrating the plurality of thread apertures to stitch the edge of the covering between the two sides of the seam, and a light-emitting device disposed in the sphere. The light-emitting device includes a light-emitting unit, a power unit, and an electrical insulating unit breaking an electrical connection between the light-emitting unit and the power unit. The electrical insulating unit is removable. The electrical connection between the light-emitting unit and the power unit is provided when the electrical insulating unit is removed such that lights emitted by the light-emitting unit penetrate the sphere and are visible through the seam and the thread apertures.

A device is provided that has an arcuate guide disposed about a shoe. The guide has a start point on an inner side of the shoe, an intermediate point on a heel side of the shoe, and an end point on an outer side of the shoe. The guide is angled upward across the heel side from the inner side to the outer side with the angle in a range between 30 degrees to 60 degrees. The start point and end point are positioned on the shoe at a point lower than the intermediate point. An indicator is moveable along the guide. The indicator is an alert that the user has executed proper body motions during a swing or throw, when the indicator traverses from the start point through the intermediate point to the end point.

Disclosed are systems, devices, and methods for using virtual or augmented reality in sports training, an exemplary method including detecting a position of a real ball, determining a trajectory for a virtual ball, the trajectory intersecting with the detected position of the real ball, displaying, by a virtual or augmented reality display device, a virtual pitch of the virtual ball along the trajectory intersecting with the detected position of the real ball, detecting, by a sensor included in a glove worn by the player, vibrations caused by an impact between a bat held by the player and the real ball, determining whether a level of the vibrations is within a predetermined range, sending a signal, to a speaker, when the level of the vibrations is within the predetermined range, to cause the speaker to emit an audible tone, and emitting, by the speaker, the audible tone.

[Object] To realize a system that can more accurately analyze a movement of a body with a simpler configuration. [Solution] An information processing device includes: a first member that includes a substantially plate-shaped casing and a predetermined detection unit; a second member that includes a substantially plate-shaped casing and that holds a battery inside the second member; and a connection unit that includes an elastic body and connects a part of an outer circumferential end surface of the first member to a part of an outer circumferential end surface of the second member such that a surface direction of one surface of the first member substantially matches a surface direction of one surface of the second member. The information processing device is worn on a predetermined body part such that the one surface of the first member and the one surface of the second member are located on a side of the body part.

Embodiments herein provide systems, methods, and computer-readable medium for providing customized exercise-related recommendations. Utilizing machine learning algorithms, a classification model may be trained with fitness-related information (e.g., exercise information, user profile information, and/or vital sign information) of a group of users. The classification model may be configured to output a classification for input data (e.g., fitness-related information of a particular user). A recommendation corresponding to a classification may be identified and provided to a particular user. User compliance with provided recommendations and subsequent user progress may be tracked to determine when recommendations were effective at bringing about a desired result (e.g., progressing the user toward a goal). Additionally, the system may determine when classifications have been inaccurately determined and/or when expected progress data has not provided a realistic path by which a user may progress toward a goal. Thus, classification, recommendation, and progress path accuracy/effectiveness may increasingly improve over time.

An exercise machine for performing an exercise motion. A resistance mechanism controls a resistance for performing the exercise motion. An incline adjustment device controls an incline for performing the exercise motion. A control system is operatively coupled to the resistance mechanism and the incline adjustment device and is configured to receive a resistance setting for controlling the resistance, receive an incline setting for controlling the incline, and determine a resistance modifier for adjusting the resistance based on the incline setting. The control system is further configured to adjust the resistance setting based on the resistance modifier to provide a modified resistance setting, control the incline adjustment device based on the incline setting, and control the resistance mechanism based on the modified resistance setting to thereby cause an exertion by a user for performing the exercise motion to change when the incline setting is changed.

A device for physical exercise for motor rehabilitation includes a body formed of a casing with at least a part made of a translucent flexible material, the body having an inner chamber and at least one opening, a closing element, housed in the opening, on which at least a pressure sensor, a light source, a control unit and a battery are mounted, in which the pressure sensor is positioned so as to detect the pressure in the inner chamber and in which the control unit is configured to receive the measurement of the pressure value and to control the activation state of the light source according to the parameter.

A system and methods of fitting golf clubs, and more particularly, the systems and methods related to wedge type golf clubs, having multiple sole configurations and/or bounce angles. More specifically, the present invention is directed to system and methods that enable a player to quantify the performance of the golf club's sole interaction with the ground and to determine the sole configuration and bounce angle that provides the most optimal shot performance.

The present disclosure relates to systems and methods for elastic delivery, processing, and storage for wearable devices based on system resources. For example, a wearable apparatus may have at least one battery; at least one sensor configured to measure at least one property associated with a user of the wearable apparatus; at least one memory storing measurements from the at least one sensor and instructions; at least one transmitter configured to send data to a device remote from the wearable apparatus; and at least one processor configured to execute the instructions to: receive, from the at least one battery, an indicator of a charge; and based on the received indicator, sending a command to the at least one sensor to operate in a low-power mode or a high-power mode, the low-power mode having. a lower sampling rate than the high-power mode.
