An Internet of Thing (IoT) device includes a transceiver coupled to a processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A training assembly structured to facilitate a swing motion of a user, during performance of a sports activity, including a receiver and a transmitter both mounted on predetermined portions of the user's body, such as the hip and arm. The arm mounted transmitter is movable relative to the receiver and is structured to communicate and activating signal to the receiver when disposed a predetermined distance there from, representative of a reactive segment of the swing motion. The receiver is structured to generate and deliver and indicating signal to the user for purposes of indicating that the reactive segment of the swing motion has been reached. The reactive segment is thereby determinative of when the user instigates a complementary adjustment of the user's body, during the swing motion, such as rotating the user's hips during a preferred part of the swing motion.

A system for automatically scoring and umpiring a cricket or baseball game without human scorers or umpires. The system collects data from smart sports equipment and automatically updates the score and performs umpiring functions. The system synchronizes smart equipment used during gameplay, obtains sensor data from the smart equipment, performs signal processing and pattern recognition on the sensor data, and performs cricketing and baseball tasks. The system may detect tosses, detect calls, infer who won the toss, capture whether batting or fielding is chosen first, identify players, authenticate a valid field state to begin game play, identify the batsman taking guard, signal the commencement of the game, detect a valid ball that is bowled, track the scores, understand the end of an over and falling of wickets, and/or declare the winner. The system enables one to conduct and administer a large number of cricket or baseball games without human umpires.

A basketball tracking system includes a basketball that is manipulated during game play with respect to the game of basketball. A first remote tracking unit is coupled to the basketball to detect when the basketball is touched. A second remote tracking unit is worn during game play. A basketball court is provided and the basketball court has a perimeter and a pair of basketball goals. A base tracking array is positioned around the basketball court and on each of the basketball goals. Each of the first and second remote tracking units is in electrical communication with the base tracking array. The base tracking array tracks a location of the basketball on the basketball court during game play. The base tracking array storing data received from the basketball during game play to facilitate the date to be subsequently analyzed.

The technology described herein relates to weight and activity monitoring footwear. In an implementation, an article of footwear is disclosed. The article of footwear includes a sole, a plurality of pressure sensors, a motion sensor, and a microcontroller. The sole has a plurality of pressure chambers. The plurality of pressure sensors take pressure readings from the plurality of pressure chambers. The motion sensor senses motion of the article of footwear. The microcontroller is operatively coupled with the plurality of pressure sensors and the motion sensor and is configured to detect when a subject enters a standing state from the motion of the article of footwear, and in response to detecting the standing state, determine a weight applied by the subject against the sole from the pressure readings. The plurality of pressure chambers are disposed to support the weight applied by the subject against the sole in the standing state.

An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.

A shooting system includes a collapsible ball capture support adapted to support a ball capture device and a ball return. The ball return detects a ball captured by the ball capture device and returns the ball to a user in response to the detected ball. To return the ball to the user, the system identifies a location of the user with respect to the shooting system, orients the ball return toward the user, and accelerates the ball along a trajectory based on a distance between the user and the shooting system.

A device is used for carrying out movements by shifting the center of gravity and/or actuating muscles of a human body. A user lies on the device and shifts the center of gravity by moving his or her hip region in order to incline a movable part of the device including the user's own body in different directions. Furthermore, the user wears video goggles or the like during the process and can move in a virtual environment using the overall system, which includes the video goggles and the movement device and can interact with these. The movements caused by the user can be generated solely using gravity by shifting the center of gravity. Additionally, the movements of the device are influenced by motors or dampers arranged in or on the device.

A system for using multiple electronic control and tracking devices for mixed-reality interaction, comprising an electronic control device that communicates with a plurality of electronic devices via a network, that receives user interaction and conveys it to devices via the network, and that receives interaction from other devices via the network and conveys it to a host device, and a method for nested communication between multiple electronic control devices and electronic systems.
