Computing device enhanced training environment system comprising a computing device, I/O subsystem for permitting a user to enter at least one attribute of the tmining or of the trainee, a plurality of sensors for generating sensory information, a training environment in which a training activity takes place, a database containing training related information. The computing device enhanced tmining environment system configured for at least one of the following: design a training program for a plurality of users, monitor training program performance, monitor training performance, instruct a user about the training, determine and/or set difficulty level in training apparatus.

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 preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.

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.

Presented is an apparatus and system for an artificial turf system. The artificial turf system includes a backing layer having a plurality of fibers extending therefrom. The artificial turf system further includes a plurality of impact sensors located at least partially on, in, and/or beneath the backing layer, wherein the plurality of impact sensors are operable to detect a force or pressure applied to the backing layer.

Hand held weight units of light weight manufactured as a solid unit, a shell unit with core insert combinations or modular units with interlocking ends. Shell units with core inserts and modular interlocking units allow for the changing of held weight by inserting or removing inserts or by locking or unlocking of modular weight unit sets creating varying held weight. The weight units are primarily used with upper body exercises during aerobic exercises in the home, outdoors, or in a gym setting such as walking or running to vary the intensity of workout during use.

A method comprises detecting, by one or more processors of a wearable device, a tag identifier of a tag located on exercise equipment. The method also comprises selecting, from a memory of the wearable device, an algorithm from a plurality of stored algorithms responsive to the algorithm having a stored association with the tag identifier and receiving, from a sensor of the wearable device, movement data of a user performing an exercise associated with the exercise equipment. The method may also comprise executing the selected algorithm using the received movement data as input and determining, when the user has completed one repetition of the exercise based on the execution of the selected algorithm using the received movement data. The method may also comprise transmitting a record comprising repetition movement data that was received during the one repetition to a remote computing device.

Methods and systems for force and inertial sensing in a garment. The system may include one or more wearable garments. The one or more garments may include one or more layers and an outer surface. Additionally, a force sensing array including a plurality of force sensing resistors, an inertial measurement unit, and a transmitter unit may be disposed within the one or more garments. A processor may comprise one or more receivers and may connect to the force sensing array, inertial measurement unit, or transmitter unit.

The invention relates to social activities typically based on physical manipulation of objects to achieve an objective common to the participants or to allow participants to engage in distinct activities on a shared field of play, part of which is physical and part of which is virtual and rendered on one or more displays. The invention provides a system and method to enable multiple participants (users) to engage in the activity sequentially or simultaneously, based on the context and objectives of the game. The activity includes one or many shared physical environments modeled on a computing system and displayed, in high fidelity, by one or more projectors or screens.
