A game practicing system for practicing a game involving propelling a playing piece into a goal of a goal post, by a player, includes one or more game practicing apparatus, and a user interactive device. The game practicing apparatus includes a target member having a target face, a target indicative lighting, and a vibration sensor. The target indicative lighting is configured to be illuminated to indicate the player to propel the playing piece on the target face. The vibration sensor to detect if the playing piece hits the target face. The user interactive device is wirelessly coupled to the practicing apparatus to: illuminate the target indicative lighting of game practicing apparatus to indicate the player to propel the playing piece on the target face; and detect if the playing piece hits the target face of the illuminated target indicative lighting.

Methods, systems, and techniques for automated detection of goals and announcement of same are provided. The system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and, when an infrared signal is received, the microcontroller automatically triggers one or more annunciator devices, such as visual, auditory, or haptic devices, to automatically indicate that a goal has been scored without human intervention.

A rebounding device for sports balls including a frame defining a frame opening, a net disposed within the frame opening, a cable extending around a perimeter of the net and a cable tensioning system configured to tension the cable around the perimeter of the net and thereby pull the net taut within the frame opening.

A smart soccer goal for tracking and communicating motion of objects includes a goal frame; a net coupled to the goal frame including a plurality of lights; and one or more sensors coupled to the goal frame. A first sensor of the one or more sensors is directed to detecting movement within and immediately near the smart soccer goal and a second sensor of the one or more sensors is directed to detecting movement outside of the smart soccer goal.

A sports and performance media positional detection system, comprising: at least two elements, with at least one element involved in the sporting activity; a power source; and machine-to-machine communication, which are collectively arranged such that if any two or more elements interact, their electromagnetic properties can be detected thus allowing the position of the interacting elements to be communicated to a decision maker. The system can be applied to at least one stationary element, which can be the playing surface, lines defining the boundaries, or a set of goalposts; and at least one moving element, which could be a ball, footwear, or the participants themselves. The system can also be applied to performance media capture.

A mobile, free standing field sport shooting target device, including a pole having a first end and a second end, wherein an opening is located at the first and second ends of the pole, a counter weight plate having a plurality of openings, wherein the counter weight plate is located adjacent to the first end of the pole, and a collar operatively connected to the first end of the pole, wherein the collar has a first end and a second end such that the counter weight plate is located adjacent to the first end of the collar and the collar is used to retain the counter weight on the first end of the pole, and wherein a distance between the first end of the pole and the second end of the collar can be adjusted.

According to one exemplary embodiment, an apparatus, system, method and/or computer program product may provide an electronically and programmably controlled remote virtual spectator/viewer device enabling viewer interaction with an entertainment participant in an entertainment forum via an exemplary digital video camera, digital audio microphone, speaker system, and display device system coupled via at least one communications interface to a communications network to allow a remote viewer to virtually interact with and communicate with the entertainment participant in the entertainment forum. Embodiments may include a graphical user interface configured to allow control of a digital video camera, and digital microphone in the entertainment forum, by a remote user from a remote location.

An integrated multi-purpose hockey skatemill with a movable skatemill belt that includes a stationary area of the artificial ice with a front face of the work area wherein a movable skatemill belt is built in by means of barrier-free transition areas with a system of spaced signalization/display elements hung on the tiltable/sliding brackets at the frontal and lateral sectors with respect to the center of the movable skatemill belt. A safety restraint system and a stabilization system are anchored above the movable skatemill belt. A tensile/compressive force measuring system is suspended from above in the longitudinal axis of the movable skatemill belt. The skatemill includes an electronic control system controlling the operation of the movable skatemill belt's drive system, the system of signalization/display elements, the system of optical scanning cameras and the tensile/compressive force measuring system. Two puck feeders are located on the border line defining the front side of the work area. A hockey goal structure with target zones impact detection sensors is located on the edge of the work force in front of the movable skatemill belt. Two laser markers used to define the width of a skate track may be located on the stationary area of the artificial ice in front of the movable skatemill belt.

A target assembly that is configured to withstand high-velocity impact from a projectile. These configurations may comprise elastic members, or “bungee” cords, that generate elastic forces to return the target assembly to its orientation prior to impact. The bungee cords are less likely to undergo inelastic deformation; so these components afford the target assembly with longer life or longevity under heavy duty cycles.
