Tough, low-friction street hockey pucks are constructed as regular prismatic cylinders or prismatic cylinders having alternating side profiles. An internal chamber partially filled with a granular material such as sand, gravel or metal shot, or fluids such as water, oil, alcohol or ethylene glycol, and combinations thereof, helps deter a rolling motion of the puck and causes it to fall down and slide. The sliding motion is more similar to an ice-hockey puck traveling over ice, so practicing with the inventive street-hockey puck is more like ice-hockey practice.

Virtual and augmented reality sports training environments are disclosed. A user interacts with virtual players in a simulated environment of a virtual reality sporting event. In some embodiments, the user's actions and decisions are monitored by the simulated environment. The environment evaluates the user's performance, and provides quantitative scoring based on the user's decisions and timing. Coaches and other users may design customized scenarios or plays to train and test users, and the resultant scores may be reviewed by the coach. In one application, real life pitchers and their pitching data are tracked and replicated in a simulated pitching environment. A team of users may practice against a simulation of a pitcher they are about to compete against, swinging at pitches that they would see in a real game. Such environments may maximize effective practice time for users, and help develop better players with improved decision-making skills.

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.

The invention relates to a teeth protector device (1) consisting of a rail which has a U shape or a channel shape in the cross-section, is adapted to a toothed jaw (5) of a user, and is made of a deep-drawn plastic. The rail has two plastic films (3, 4) which are laminated onto each other and between which an insert (2) is located, said insert being provided in a central front region and having a lateral extension which corresponds to multiple teeth of the user and has a width that corresponds to the distance from an approximately coverable teeth tip region to the gums. The insert (2) is a molded part made of light- or laser-cured plastic using a 3D printer.

An active footwear suspension system is disclosed. The footwear system provides dynamic suspension using at least one or more variable resistance beams. At least one or more VRB from an anchor plate positioned forward of and/or aft of an arch section of the footwear, thus providing selectable suspension to the wearer. The selected rotation of the VRBs from a first position to a second position provides customized suspension between a minimum resistance to a maximum resistance per zone.

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 system and method for using performance signatures can include generating a set of performance features during an activity of the first participant by collecting kinematic data from at least one inertial measurement unit and generating a set of biomechanical signals; combining the set of performance features into the performance signature; generating at least a second performance signature from a set of participants; comparing the performance signature of the first participant to at least the second performance signature; and applying a result of the comparison to an interaction with at least one participant.

A reflexive training device having a rotating member that rotates around an axis while also traveling perpendicular to the plain of rotation to present the rotating member at variable vertical locations during use.

A puck embedding at least one transmitter circuit, and a method for producing a puck embedding at least one transmitter circuit. To protect the electronics from displacement or damage, the puck employs a layered structure. The puck has a centrally located cavity, containing a carrier structure having a rigid shell, at least one transmitter circuit supported by the carrier structure, and a battery provided within the carrier structure. The battery is embedded in a first elastic material provided within the carrier structure. The carrier structure is embedded in a second elastic material provided within the centrally located cavity.

Systems and methods for motion capture and analysis are described. The system may include a motion sensor unit configured to capture data associated with movement of an object. The motion sensor unit is configured to be directly or indirectly coupled to the movement object at a first location. The system also includes a processor to process the captured data to determine one or more values and to translate the data and/or values to correspond to a second location on the movement object located away from the first location. The data and/or values, including translated data and/or values, may be transmitted by wireless transmitter and displayed by a display unit.
