A grip adjustment system comprising: a sleeve positionable, in use, on an object configured to be gripped by a user. The system also comprises a distributed array of actuators, each actuator being arranged to actuate a respective portion of the sleeve between a first position and a second position in response to an actuation signal; and a processor. The processor is operable to: receive a pressure distribution and an event quality indicator corresponding to an event of interest; determine an optimal grip based on the pressure distribution and the event quality indicator; select an actuator, of the distributed array of actuators, to be actuated based on the optimal grip; transmit the actuation signal to the actuator such that the shape of the sleeve is changed and the grip of the user is adjusted.

A sports training device attached to the shaft of a swinging sports apparatus, such as a baseball bat. The device includes a drag chute disposed between two rigid members, a support rod disposed between the two rigid members along the longitudinal axis of the chute, and a plurality of coupling elements connected to the support rod. Each coupling element includes an annular opening for positioning of the sports apparatus therethrough. One coupling element has a stationary component that secures the device to the sports apparatus and a rotating component that rotates 360 around the sports apparatus. As such, the entirety of the device, with exception to this stationary component, can substantially freely rotate 360 around the sports apparatus. Resistance during a swing can be adjusted by sliding the coupling mechanisms along the support rod to expose more or less of the chute.

Aspects directed towards a training apparatus are disclosed. In one example, a bat sleeve having a substantially cylindrical shape is configured to remain affixed to a desired point of impact on a baseball bat. The bat sleeve includes a first open end having a first inner diameter and a first outer diameter, and a second open end having a second inner diameter and a second outer diameter. In another example, a training apparatus includes a bat portion and a sledgehammer portion. The bat portion has a form factor substantially similar to a lower portion of a baseball bat, whereas the sledgehammer portion has a form factor substantially similar to an upper portion of a sledgehammer In yet another example, a training apparatus includes a sensor portion coupled to a striking portion. Here, the sensor portion is configured to sense an impact between the striking portion and a target.

One or more processors may be configured to receive, via a radio from one or more sensors, one or more streams of sensor values indicating: (1) accelerations of a boxer's arm within a first range of acceleration, measured by a first acceleration sensor, (2) accelerations of a boxer's arm within a second range of acceleration, measured by a second acceleration sensor, and (3) rotation of the boxer's arm measured by a gyroscope sensor. The one or more processors may be configured to determine, based on the received sensor values from the first acceleration sensor, whether a punch landed but not to measure a force or velocity of the punch. The one or more processors may be configured to determine, based on the received sensor values from the second acceleration sensor, at least one of a force or a velocity of the punch but not to detect whether the punch landed.

A core muscle training apparatus and method is described. The apparatus comprises a harness that is worn by the user, to which a pair of resistance leads are connected at opposing sides of the user's waist approximately above the hips. A resistance force is applied through the resistance leads against an effort force exerted by the user in order to stimulate recruitment and activation of the targeted muscles. By adjusting the direction and the amount of resistance force applied to the resistance leads, the demand on the muscles being targeted can be controlled. The core muscle training apparatus according to embodiments of the present disclosure further offers versatility in the environment in which it can be used. The apparatus can be used, for example, when the user is in a static position or can be used during dynamic functional movements.

A sports simulation system comprises a projectile tracking apparatus configured to detect a projectile traveling through a projectile tracking region towards a display surface, a controller comprising one or more actuatable buttons, each actuatable button configured to communicate one or more control signals in response to actuation thereof, and at least one processing stage configured to receive data from the projectile tracking apparatus and determine three-dimensional positions, velocity and acceleration of a detected launched projectile traveling through said projectile tracking region, the three-dimensional positions, velocity and acceleration used by said at least one processing stage to calculate a trajectory of said launched projectile into a three-dimensional sports scene, receive one or more control signals from the controller and determine one or more control commands of one or more animated objects based on the one or more control signals, and use said calculated trajectory and said one or more control commands to generate updated image data including a simulation of said launched projectile into said three-dimensional sports scene and manipulate one or more animated objects associated with said three-dimensional sports scene, the updated image data associated with a sports result.

A method of customizing a golf club, wherein the method includes generating operating data representative of a user operating a mechanical device. The operating data is generated by a first sensor sized and configured to be removably positioned in a mounting port formed on the mechanical device during operation of the mechanical device. The sensor is interchangeably positionable in the mounting port with at least one mass insert, the at least one mass insert being adapted to be interchangeably positioned in the mounting to provide at least two different mass configurations. The method further includes determining a recommended configuration of the at least one mass insert specific to the user based on the operating data generated by the sensor, and transmitting information representative of the recommended mass insert.

A sporting robotic device apparatus, system, method and/or computer program product may provide an electronically programmably controlled sporting device. Certain embodiments include a plurality of sporting devices coupled to a robot or a plurality of the at least one robots, where the plurality of robots each include a sporting device coupled to the plurality of robots, and where each robot includes a plurality of joint axes, motors, and structural members. The sporting robotic device can further include an electronic user interface coupled to the robots and an electronic computer processor, memory, input and output devices, and can include further features as claimed including at least one of the user interface with devices coupled thereto, the computer processor configured to save or retrieve a sporting routine from memory, to randomize a challenge, or configured to combine sporting routines, or shuffle sporting routines, previously saved.

A sports training device has a circular main housing having opposed top and bottom surfaces each having a plurality of bosses formed thereon, a channel formed within an intermediate housing section of the main housing and extending therethrough, and a fastening mechanism seated within the channel and secured to the main housing by a fastener. The fastener mechanism can include a first fastener part and a separate and independent second fastener part that can be coupled together.
