Systems and techniques for a sensor network for trick classification are described herein. A first data stream may be received from a first sensor array affixed to a first free-moving body of a sporting device. A second data stream may be received from a second sensor array affixed to a second free-moving body of the sporting device. A trick region of a predetermined length of the first data stream corresponding with an occurrence of a trick may be determined using data from the first data stream. The trick may be classified using a first set of data from the first data stream corresponding with the trick region and a second set of data from the second data stream. The second set of data may be obtained by aligning the trick region of the first data stream with the second data stream.

A poker-incorporated sports game is provided. The sports game includes elements each bearing indicia, or marking, of a playing card, such as playing cards used in a poker card game. The participants of the sports game have to perform and meet one or more predetermined challenges or tasks to achieve a poker hand from the elements. The participants strive to meet the challenges in the shorted time possible. An algorithm is then used to calculate the score of each participant, based on the value of the poker hand of and time used by the participant to achieve the poker hand.

A water bottle holder for equestrian environments includes a cup configured to hold a water bottle, a pair of arms configured to be positioned in proximity to opposing sides of a jump post of an equestrian jumping standard, and a removable pin configured to be inserted through apertures in the pair of arms and a hole of the jump post that is at the desired height. The cup can include a drainage hole. The cup can be configured to hold other items. The water bottle holder can include a tether that connects the removable pin to the rest of the water bottle holder. The water bottle holder can include hooks in the pair of arms and a standoff to secure the water bottle holder to a horizontal structure. The water bottle holder can include knobs for attachment to a keyhole track that can be associated with the jumping standard.

Various embodiments facilitate location-aware distributed competitions. In one embodiment, a system facilitates a distributed sporting event that includes multiple players traveling over non-uniform courses that are remote from one another. The system includes a manager that receives state information, such as location information, from client devices used by each of the players. The manager then transmits location information for each of the players to the client devices, which are each configured to present a graphical representation, such as a map annotated with the locations of each of the players. The system corrects for disparities between the non-uniform courses traveled by the players, for example by mapping a location on a course traveled by a first player to a location on a course traveled by a second player. Various mechanisms for establishing the mapping between non-uniform courses are also described.

Disclosed are apparatuses and methods useful for providing a visual indication to the rider of a horse of one or more inputs, such as the pitch of the head of a horse. The apparatuses and methods are useful in connection with the sport of dressage. The rider can be notified of a position or orientation of the horse's head, of rein tension, of the rider's body position or orientation, of a current location within a course or routine, of a warning, or of other information. The visual indication can be in the form of an illuminated light source.

Apparatus and method for sports throwing cage. The apparatus might be a pole with multiple curtain couplings and multiple points of contact, a support, and a bend. The curtain couplings hang a vertical net curtain. The support and the bend adapt the bent pole to provide an offset from the vertical net curtain.

A system and method of conducting a drone race or game in a contained area is disclosed herein. The system may also include cameras attached to the drones and the video feed from the camera is transmitted to a computing device used to control the drone and to display the video feed. The system may also use computing devices and monitors to display the video feeds from the cameras attached to the drones. The system may also be configured as a game with information points.

The baton stand is a training device that is configured for use with a baton that is used in the relay race events of a track and field competition. The baton stand is a container within which a baton can be placed or removed as a runner passes by the baton stand. The baton stand is adjustable such that the baton stand will simulate the angle and height the baton should be in during the acceptance or hand off of the baton. To use the baton stand, a runner runs past the baton stand and, depending on the objective of the training exercise, will place the baton into or remove the baton from the baton stand. The baton stand comprises a telescopic stanchion, a stand, a basket, and a locking hinge. The stand attaches to the telescopic stanchion. The locking hinge attaches the basket to the telescopic stanchion.
