A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight, and / or one or more observers in the area. The feedback information may include one or more trajectory parameters that the human may use to evaluate their skill at sending the object along a desired trajectory. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving objects may be used to evaluate trajectory parameters for a basketball shot at a basketball hoop by a player. The feedback information, such as a trajectory entry angle into the basketball hoop and / or an entry velocity into the hoop for the shot, may be output to the player in an auditory format using a sound projection device. The system may be operable to be set-up and to operate in a substantially autonomous manner. After the system has evaluated a plurality of shots by the player, the system may provide 1) a diagnosis of their shot consistency, 2) a prediction for improvement based upon improving their shot consistency and 3) a prescription of actions for improving their consistency.

The present invention is an article and process for determining the site of impact of a movable object on a treated surface, where a tennis ball is treated with a striking composition, and a boundary line region is treated with a receiving composition such that when the striking composition and the receiving composition are in physical contact, a calorimetric indicator is left on the receiving composition to indicate the point of contact.

A ball game system for training and / or play comprising a one or more playing areas suitably large to accommodate running and jumping players, each playing area including adjacent surface areas forming a court and having distinctly different properties, such as a first surface suitable for bouncing a ball and a second surface comprised of a deformable elastic material. The system includes an automatic ball feeder and sensors for monitoring the positions and trajectories of one or more players and / or balls on the court. Options include visual displays and / or audio outputs reflective of player performance, and payment-driven operation of the system components, including a means for adjusting the degree of rebound provided by the deformable elastic surface(s).

A muscular memory training apparatus and method of the present invention is used for training basketball players to shoot a ball to a ring from fixed distances. The apparatus provides numerous advantages including improved training aid and method that teaches the players in a correct manner of making a shot with a basketball, develops muscular memory of the body joints and muscles for proper execution of a basketball shot and makes higher percentage of hitting the goal.

A temporary visible image, such as a first down reference line, corporate logo, or text is projected onto a target surface by an orientation-stabilized, fiber-fed laser projector. The projector may include at least one cylindrical lens or at least one pair of X-Y scanners. One or more remotely located lasers, supplying optical energy at a single wavelength to the projector, accommodate projection of a monochromatic line pattern. Multi-colored images are accommodated by supplying, to the projector, the output of a plurality of lasers operating at different wavelengths within the visible band. The projector is suspended and conveyed as a unitary assembly by a suspension system adapted to maintain the projectors angular orientation and dynamically stabilize the image. If desired, two or more independently-suspended projection modules or groups of modules adapted to move in unison or independently over the length of the field may be employed.

A volleyball training apparatus is disclosed that generally includes a standard assembly, a support assembly mounted on the standard assembly, a ball assembly, and a ball suspension assembly mounted on the support assembly and supporting the ball assembly. The ball assembly may be secured to the ball suspension assembly in a manner such that the ball assembly remains secured to the ball suspension assembly upon spiking of the ball assembly by a user. In some embodiments of the invention, the ball suspension assembly comprises an elongate elastic member having opposite ends attached to the ball assembly. In some embodiments, the support assembly comprises a support member having a passage therethrough, and the ball suspension assembly comprises an elongate elastic member with a portion of the elongate elastic member extending through the support member.

A multi-filamentous net or mesh comprising an image visible on only one side is provided. The image is visible only from the primary viewing position without the paint or ink composition absorbing through the fibres to be visible from the back of the net or mesh. This permits the use of multi-filamentous nets or mesh for images or logos without disrupting the spectators' view and / or the use of both sides of the net or mesh for unidirectional images or logos.

An outdoor game system includes a pole adapted for anchoring to the earth. A water-carrying conduit extends upwardly through the pole and is rotatable within the pole. A sprinkler is mounted atop the pole and is connected to the conduit. A reel is affixed to the conduit within the pole adjacent an opening in the pole. The reel is rotatable with the conduit. A net, capable of extension from the opening in the pole, is wound upon the reel. An elongated cover is provided for closing the opening in the pole. The cover is connected to the net for supporting the net above the earth, when the net is extended from the opening in the pole. A handgrip, for rotating the conduit to rewind the net upon the reel, is affixed to the conduit beneath the reel.

A frameless portable suspension system includes a tensional two-dimensional material having a frameless perimeter, opposite upper corners, and a bottom secured to ground, the tensional two-dimensional material located in a vertical plane perpendicular to the ground; a pair of adjustable spring mechanisms coupled to the upper corners and providing the upper corners in tension in an upward vertical direction and a outward horizontal direction, and wherein the tension in the tensional two-dimensional material is adjustable with the adjustable spring mechanisms while the tensional two-dimensional material is under tension and the tensional two-dimensional material is positionable in a vertical plane perpendicular to the ground upon adjustment of the tension in the tensional two-dimensional material with the adjustable spring mechanism.
