A portable sports rack and delivery system including an elongate rack enclosure, and a method of use thereof are provided. The elongate rack enclosure defines a storage space for accommodating balls stacked one above the other. A delivery opening, disposed at a first end of the elongate rack enclosure, receives, accommodates, and delivers an uppermost ball from the storage space. A base member, attached to a second end of the elongate rack enclosure, supports the stacked balls within the storage space. A release component including a compression spring, disposed on an upper surface of the base member, elastically compresses and expands to elevate and release the uppermost ball from the storage space for delivery through the delivery opening. A training component, operably and adjustably coupled to a rear section of the elongate rack enclosure, extends above the first end of the elongate rack enclosure to assist in training a sportsperson.

A method for generating or modifying movement signatures includes receiving a request to generate a movement signature, receiving first sensor data from one or more sensors of a first wearable device associated with a first user, the first sensor data being generated with one or more of an accelerometer, a gyroscope, or a magnetometer of the wearable device, and associating the first sensor data with the movement signature and storing the sensor data. The method also includes receiving second sensor data from one or more sensors of a second wearable device associated with a second user, the second sensor data being generated with one or more of an accelerometer, a gyroscope, or a magnetometer of the second wearable device, analyzing the second sensor data in comparison to the first sensor data, and based on the analysis: generating a notification, or modifying the movement signature.

A method includes receiving motion data of a user in an environment with respect to a plurality of instances of a first action by the user, determining a kinematic movement based on receiving the motion data, analyzing the kinematic movement using a neural network, obtaining a plurality of outcome types with respect to the first action of the user, correlating the kinematic movement with the at least one indication of the outcome type with respect to the first action, classifying an outcome of the first action as at least one of the plurality of outcome types, determining which of the kinematic movements of the user result in the at least one of the plurality of outcome types, and providing instructions to the user to alter the determined kinematic movements of the user that result in the at least one of the plurality of outcome types.

Provided is an apparatus, method, and system for simulating a defender of a sport activity.

An exercise assisting device includes at least one processor. The processor obtains motion data on a current exercise form of a user performing a certain repetitive exercise motion including a certain motion state. Based on the obtained motion data, the processor determines a point of time at which the motion state occurs in one cycle of the repetitive exercise motion. Based on the obtained motion data and the point of time, the processor obtains the current exercise form in the motion state. The processor obtains a difference between the obtained current exercise form and a target exercise form. The processor causes an actuator to apply a stimulus to a body of the user based on the difference. The actuator is attached to a part of the body of the user constituting the exercise form. The stimulus suggests correction of the exercise form and indicates a direction to move the part.

Presented are wearable sensor systems for monitoring user movement, methods for making/using such systems, exoskeletons employing such systems, and wireless-enabled wearable sensor devices for performing biometric measurements. A sensor system for monitoring movement of a user includes a wearable sensor device that is communicatively connectable to a sensor linking node. The sensor linking node wirelessly receives sensor data from the wearable sensor device and wirelessly communicates the received sensor data to a remote computing node. The wearable sensor device includes an expandable device body, such as an elastic compression sleeve or an adjustable strap, that is worn on an appendage of the user. The device body includes a mounting interface, such as mating hook-and-loop fastener pads, that removably mounts thereon a biometric sensor core (BSC) unit. The BSC unit contains a microcontroller assembly that is integral with a microcontroller device, a biometric sensor array, and a wireless communication device.

The utility model relates to the technical field of throwing toys, and discloses a structure of a lighting effect structure for a sandbag game board. The lighting effect structure for a sandbag game board includes a lighting effect assembly, a sandbag board configured to mount the lighting effect assembly, and a remote control configured to remotely control the lighting effect assembly. The lighting effect assembly for a sandbag game board includes a hole light strip, a board light strip, a sensing detection module configured to detect that a sandbag enters a hole, a vibration detection module configured to detect that the sandbag hits a board, and a voice playback module configured to perform voice prompt in cooperation with the sensing detection module and the vibration detection module. The hole light strip is embedded in an inner part of a hole on the sandbag board, and the board light strip is embedded at an outer edge of the sandbag board. According to a design that the hole light strip and the board light strip are embedded in the sandbag board, appearance of the sandbag board is ensured. Due to disposing of the hole light strip, the board light strip, the laser sensor, the vibration sensor, and the loudspeaker, the lighting effect is displayed and a corresponding voice prompt is played back while the sandbag hits the sandbag board or entering the hole. Therefore, interactivity is high, and interestingness of a sandbag throwing game is improved.
