A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive an activity metric. The processor is further configured to display, via the display system, the activity metric, wherein the display system is disposed in the eyewear so that the activity metric is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.

The present invention provides a device comprising a fastening ring configured to mechanically attach the device to a lacrosse stick, a display screen having a rectangular shape, the display screen attached to the front part, a first button positioned on one side of the display screen, a second button positioned on one side of the display screen and a third button positioned on one or more sides of the display screen.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

A ball machine system comprising a ball launching system, a memory configured to store a court model that includes dimensions of a court type in relation to a three-dimensional (3D) coordinate system, an imaging system connected to the ball launching system and configured to capture a plurality of images of a court, and a processor. The processor configured to analyze the plurality of images to detect feature points in each of the plurality of images, superimpose a plurality of different transformations of the court model onto the plurality of images to generate a plurality of model fits, select as a final model fit, from the plurality of model fits, a model fit based on a degree of overlap among features of the transformed court model and the respective image, and calculate the position of the ball launching system on a playing surface of the court based on the selected final model fit and intrinsic parameters of the imaging system.

A system for data collection during a game includes a positioning system for determining various locations of a user during the game, a tag reader for reading a passive RFID tag held in close proximity to the tag reader, and a processor for correlating the location of the user with the time at which a tag is read to enable action locations for the game to be determined.

A method for ball game training, the method comprising steps executed by at least one computer, the steps comprising: receiving image data of a player and a ball, the image data being captured using at least two cameras, using the received image data, tracking motion of the player and motion of the ball in three dimensions, based on the tracked motions, predicting a position of the player and a trajectory of the ball, and based on the predicted position and trajectory, generating a control command for at least one ball throwing machine.

A sports ball position reckoning system, comprising instrumentation in a sports ball that allows one or more players to be electronically located on a playing field or court each time a goal attempt is made. The instrumentation is configured to fit through the opening of an inflation port of the ball when the fill valve is removed. The system works in conjunction with a performance monitor system that detects ball interactions with a goal and is used to trigger the system to analyze the ball flight path just prior to the goal interaction. Player position is ascertained through the localization of the initial position of the ball's flight path. For multiple players, each player is pre-assigned a uniquely marked ball. The identity of the player who executed the attempt is determined through the player's association with the ball that executed the flight path towards the goal.

A computer-implemented method for determining a target situation in an athletic event. Positional information including the relative positions of a group of selected participants is initially received from a tracking system, and the aggregate motion of the selected participants is detected in real-time using the positional information. The target situation may be determined to have occurred when a change in the aggregate motion occurs in accordance with a predetermined characteristic during an initial time interval.

Athletic performance monitoring and tracking may provide multiple ways in which to track athletic movement and activity. Workouts may also be tagged with various parameters including mood, weather, terrain, athletic equipment, friends used and the like. Workout information may be shared to social messaging and networking outlets. Workout information shared may include map information including images of maps, interactive maps, links to maps, route information and the like and/or combinations thereof. Additionally or alternatively, an application may be configured to execute within a context of a social networking system to facilitate athletic activity data transfer and generation of workout entries in the social networking site.

Systems and methods facilitate autonomous image capture and/or picture production. A location unit is attached to each tracked object. An object tracking device receives location information from each location unit. A camera control device controls, based upon the location information, at least one motorized camera to capture image data of at least one tracked object.
