An inflatable game ball includes a cover formed from a plurality of panel segments attached along peripheral edges. Each panel segment an outer panel portion, having a first shape and a first size, and an inner panel portion, having the first shape and a second size, smaller than the first size. The outer panel portion is joined with the inner panel portion, such that peripheral edges of the outer panel portion are aligned, and parallel, with peripheral edges of the inner panel portion. An inflatable bladder is disposed within the cover and movable between deflated and fully-inflated conditions. When the inflatable bladder is deflated, an interior surface of the outer panel portions is separated from a top surface of the inner panel portions by a first distance. When the inflatable bladder is fully-inflated, the interior surface is in contact with the top surface of the inner panel portions.

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.

An inflatable game ball and a method of constructing an inflatable game ball is described. Panel segments are formed from an outer panel portion and an inner panel portion having different sizes, with the inner panel portion being smaller than the outer panel portion. The inner panel portion and the outer panel portion are joined so that peripheral edges of the inner panel portion and the outer panel portion are aligned. Multiple panel segments are attached together to form a cover. Due to the differences in sizes between the inner panel portion and the outer panel portion, when an inflatable bladder within an interior of the cover is inflated to a fully inflated condition, variations in the dimensions of the ball caused by stretching of the cover may be reduced or minimized. In one embodiment, an alignment guide can assist with aligning the peripheral edges of the panel portions.

Sensing devices including pliable e-textile pressure sensors are used in gloves intended to be worn against a user's hand, or a portion of a user's hand. Additional sensors, such as accelerometer(s), gyroscope(s) and geo-referencing sensor(s), may be incorporated in electronic devices that interface electronically with the pressure sensors and are mounted on or in proximity to a glove when in use. Systems and methods for storing, communicating, processing, analyzing and displaying data collected by sensor components for remote monitoring of conditions at hand surfaces, position and orientation data, movement data, and the like, are also disclosed. Sensors and sensor systems provide substantially real-time feedback relating to current body conditions, orientation and movement, and may provide notifications or alerts to users, coaches, etc., enabling early intervention when conditions indicate intervention is appropriate.

Provided herein is a multi-purpose exercise apparatus for improving sports coordination with which a user may sense stimuli from inside and outside one's body and at the same time operate one's body functions so as to adapt to the given circumstances using body muscles when playing a football, volleyball, handball, tennis, table tennis game and the like, thereby improving abilities of adjusting one's body parts such as the user's correct posture, balance, timing, flexibility, agility and the like, especially, significantly improving the ball control technique, body senses, and judgment ability of ball game players or sports participants.

Training equipment for training with ball (13) comprising an elastic line (12) attached between the ball (13) and a fixed anchoring point, wherein the fixed anchoring point is an extendable rod (11) adapted to be secured to an existing structure at a distance above ground level, such as the crossbar of a goal. The rod (11) and the elastic line (12) contribute to intermediate storage of energy when the ball's movement changes direction. The equipment can be combined with sensors and electronic communication equipment for objective assessment of the quality of performed exercises and with the possibility of keeping track of scores in games/competitions.

The present application provides a throwing training device, which includes a frame, a lifting seat, and a hinged component. The hinged component is connected to the frame and the lifting seat, the hinged component is configured to fix the frame to the lifting seat and to move the frame around the hinged component. The throwing training device has an unfolded configuration and a storage configuration, which can adapt to the needs of different throwing events through a shape adjustment, and is convenience to use and transport; the throwing training device can flexibly adjust a use height by providing with the lifting seat, thereby meeting different use needs.

The information processing apparatus generates three-dimensional shape data representing a three-dimensional shape of a first object by using a plurality of images obtained by a plurality of imaging apparatuses capturing the first object. The information processing apparatus estimates a size of the first object by using the three-dimensional shape data. The information processing apparatus specifies a position of a second object that is captured by the plurality of imaging apparatuses based on results of a comparison between the estimated size of the first object and a predetermined reference value.

The present invention relates to sports balls. A sports ball comprises a surface layer comprising a plurality of panels. The sports ball further comprises a lattice structure extending below the surface layer, wherein the lattice structure comprises a plurality of lattice cells comprising radially extending elements. The lattice cells which are adjacent to the surface layer have at least one dimension which is smaller than an average diameter of the panels.
