An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A sensor system includes an airbag engaged with the sole structure of an article of footwear, the airbag configured to compress and expand during use of the article of footwear, a force sensor engaged with the airbag and configured to detect force on the airbag based on changes in capacitance as the airbag compresses and expands, a port connected to the article of footwear and configured for communication with an electronic module, and one or more conductive leads extending from the force sensor to the port to place the force sensor in communication with the port. The system may be used with an article of footwear including an upper member at least partially defining a foot-receiving chamber and a sole structure engaged with the upper member.

An example system for game status detection and trajectory fusion is described herein. The system includes a tracker to obtain a ball position and a player position based on images from a plurality of cameras and a fusion controller to combine multiple trajectories that are detected via the ball position to obtain a fused trajectory. The system also includes a finite state machine configured to model a game pattern, wherein a game status is determined via the ball position, the player position and the fused trajectory as input to the finite state machine.

An apparatus includes support members, a cable, a rolling mechanism and a tackling bag. The cable is configured to extend between the support members. The rolling mechanism is configured to traverse the cable and includes first and second sets of wheels. The cable is configured to extend between two wheels of the first set of wheels and between two wheels of the second set of wheels. The tackling bag is configured for attachment to the rolling mechanism. When a downward force is applied to the tackling bag, the pulley device detaches from the wheel housing and a portion of the cable extends around one of the two wheels of the first set of wheels and around one of the two wheels of the second set of wheels to prevent the rolling mechanism from further traversing the cable once the downward force is applied to the tackling bag.

An athletic training system (200) has a data recording system (202) and a data engine (204). The data recording system (202) is configured to record an athletic competition event. The event may have a first team of players competing against a second team of players. The data engine (204) is configured to receive data associated with the recorded athletic competition event. The data engine (204) processes the data and displays the data as a replay of the event in animated form.

An apparatus includes a rolling mechanism and a pulley device. The rolling mechanism is connected to a cable and configured to traverse the cable from a first end of the cable toward a second end of the cable, the cable being attached to and extending between a pair of support members. The pulley device is removably coupled to the rolling mechanism and attached to a tackling bag, the tackling bag being configured to be tackled when propelled from the one of the pair of support members toward the other of the pair of support members. The pulley device is separated from the cable when the tackling bag is propelled from the one of the pair of support members toward the other of the pair of support members.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A first list of available players is provided to each individual user who then selects a first fantasy lineup, where selections by another individual user does not preclude other individual users from also selecting the same player. First fantasy lineups are received from each individual user, the fantasy lineups comprising one or more players selected from the first list of available players. Each individual user may provide a replacement lineup prior to the end of a game. A subsequent list of available players is provided to each user and does not include players from the first fantasy lineup. Subsequent fantasy lineups from each individual user are received comprising only players selected from the subsequent list of available players. None of the players of the first fantasy lineup for an individual user is included in any subsequent fantasy lineup of the individual user.

A sports ball is provided. The sports ball may include a bladder and a cover disposed about the bladder, wherein the cover includes a plurality of adjoining panels and defines an exterior surface. The cover further defines a plurality of channels extending radially inward from the exterior surface. The plurality of channels includes a plurality of peripheral channel segments and a plurality of interior channel segments. The plurality of peripheral channel segments each define a peripheral seam between adjoining ones of the plurality of panels. Each channel of the plurality of interior channel segments is provided within a central region of one or more of the panels and divide the exterior surface into a plurality of open polygonal portions.

A tackle training apparatus includes a padded body member and two padded elongate leg members in which each leg member has a first end for abutting the body member and a second end for contacting the ground. The two leg members are arranged in relation to the body member to extend from and to be resiliently movable relative to and/or separable from the body member, and in one configuration where the second end of each of the two leg members is placed on the ground, the two leg members can support the body member such that the apparatus is in a standing position, provides an effective training apparatus for improvements in collisions and especially tackles in rugby. Use of the apparatus facilitates improvement in point of contact, height of approach, grip technique and grip strength.
