A weight training equipment with an ultrasonic sensor assembly including a transmitter unit, a receiver unit, a case and the support. The case is rotatably supported upon the support to expose the transmitter and the receiver upwardly. A freely rotatable pin unit is selectively inserted into the hole of the corresponding weight block of the weight training equipment to have its reflection surface downwardly face the sensor assembly. A distance between the pin unit and the sensor assembly during exercise can be measure by ultrasound transmitted from the transmitter unit toward the pin unit and further reflected by the reflection surface and received by the receiver unit.

A ball game apparatus in which movements of a coded ball (20) are detected by detector units (100, 206) and an automatic indication of a player's score is given, where data relating to the ball (20) are stored in a database connected to the detector units (100, 206), the data including the code of a ball (20) and a code relating to a player to whom the ball (20) has been allocated, the ball (20) being configured to temporarily store, and to intermittently transfer to the detector units (100, 206) and thence to the database, data relating to the ball's movements. A rechargeable battery (40) is contained within the ball (20), and is arranged to be charged by a battery charging system. Features of the game may be controlled by means of a player's mobile telephone.

Exemplary embodiments of the present disclosure are directed to systems, methods, and computer-readable media configured to autonomously generate personalized recommendations for a user before, during, or after a round of golf. The systems and methods can utilize course data, environmental data, user data, and/or equipment data in conjunctions with one or more machine learning algorithms to autonomously generate the personalized recommendations.

Embodiments of the present disclosure provide a method for labeling motion data, comprising: obtaining motion data of a first subject when the first subject is in motion, the motion data representing a motion state of the first subject; obtaining image data of the first subject when the first subject is in motion; and labeling the motion data based on the image data.

A system for formulating a performance metric of a motion such as water sport motion, preferable a swimming stroke, includes a wearable sensor device including 4 pressure sensors, a 9 degrees of freedom inertial measurement unit (IMU), a microprocessor communicating with the pressure sensors and the IMU, and waterproof housing in the form of a flexible silicone band to house the microprocessor, the pressure sensors and the IMU. The system includes an external computer communicating with the device for receiving and combining input data from each of the pressure sensors and the IMU, via the microprocessor, and a processing unit configured to combine the input data from both the at least one pressure sensor and the IMU. The input data is used to infer at least one force magnitude and at least one force direction, the input data being used to provide the performance metric of the water sport motion.

Disclosed herein is a system for testing motor skills involved in locomotor, non-locomotor, and manipulative activities. The system utilizes joint data created by a motion sensor during a subject's performance of an activity to determine the subject's motor skill proficiency for that activity. The system compares the subject's joint data to benchmark data to detect one or more phases of the activity. Based on the comparison, the system also determines the subject's proficiency in the particular motor skill tested. The system is embodied in a computer-implemented application that provides various user interfaces for navigating through the user interfaces, accessing a database of the system, testing a subject's motor skills, analyzing a subject's proficiency, and facilitating practice of motor skills.

Tracking and monitoring athletic activity offers individuals with additional motivation to continue such behavior. An individual may track his or her athletic activity by completing goals. These goals may be represented by real-world objects such as food items, landmarks, buildings, statues, other physical structures, toys and the like. Each object may correspond to an athletic activity goal and require an amount of athletic activity to complete the goal. For example, a donut goal object may correspond to an athletic activity goal of burning 350 calories. The user may progress from goal object to goal object. Goal objects may increase in difficulty (e.g., amount of athletic activity required) and might only be available for selection upon completing an immediately previous goal object, a number of goal objects, an amount of athletic activity and the like.

Methods and systems for providing a fitness experience to a user. The system comprises a punching bag defining an outer non-planar surface adapted to receive strikes of the user, a sensor configured to generate data about strikes applied by the user on the punching bag, an image projecting device configured to project a dynamic content on the outer non-planar surface of the punching bag and processor communicably connected to the sensor and the image projecting device. The processor is configured to dynamically adjust the dynamic content projected on the outer non-planar surface based at least in part on data provided by the sensor.

A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement. The resistance force required to effect the first isokinetic seed movement is associated with a force-velocity profile. It is determined whether a sufficient number of isokinetic seed movements have been performed by the user. In response to a determination that the sufficient number of isokinetic seed movements have been performed by the user, a strength determination of the user is made based on the isokinetic seed movements performed by the user.

A bicycle trainer includes an electric treadmill, a controller, and a sensing unit. The electric treadmill includes an endless conveyor belt on which a user may ride a bicycle. The controller is used to control a running speed of the endless conveyor belt. The sensing unit includes a swinging member and a sensor electrically connected with the controller for sensing a swing of the swinging member and sending a corresponding signal in responsive to the swing. The swinging member is disposed across the electric treadmill and swingable back and forth relative to the electric treadmill, such that the swinging member is pushable by a bicycle wheel to swing. The controller adjusts the running speed of the endless conveyor belt based on the corresponding signal. As such, the endless conveyor belt can match the instant riding speed of the user, thereby providing good riding training and experience.
