A sports tracking and analysis system includes a RFID tag implanted onto an item associated with a player and at least one RFID tag implanted on a game ball. The tags and reader are arranged to transfer data such as the time and location of player and ball to each other for readers positioned throughout the field. The readers communicate the data to a computer system designed to process the data and generate player performance statistics including real-time measurements of many characteristics and, over time or based on input data, historical performance statistics. A method of tracking and analyzing the performance of a sports game is also included.

A snowboard binding has a support structure with a base plate and side plates that project from the base plate. Tension cables, which hold a single instep element, are attached to the side plates. The instep element extends from a toe region of the boot up to at least its instep region. A single tensioning device for the tension cables is independent of a pivoting position of a heel element.

A ride surface for water ride attractions and the like is provided. The ride surface is fabricated from a reinforced membrane material tensioned over a supporting framework. The tensioned membrane ride surface serves the dual role of providing structural support for water flow and riders thereon while at the same time providing an impact safe surface that is non-injurious to riders who may fall thereon. The tensioned membrane can be adjusted actively and/or passively in order to accommodate different and varied ride experiences. Optionally, the shape of the membrane ride surface can be changed either dynamically or passively by special tensioning techniques and/or by using auxiliary support structures such as air bladders, pressure/suction, foam supports or/or the like.

The marking device is controlled in response to the position of the vehicle according to the position sensor.

A contact configuration between boot and binding for snowboarding. Contact pins are provided on opposing sides of the boot at both the heel area and the toe area. This 4-point contact configuration assures heel and toe stability and reliable side boot restraint. Concave mating receptacles at matching locations on the binding assure easy and simple interconnection which is also secure and reliable. A release mechanism is provided to selectively retract the pins using a simple pull cord arrangement. Strap linkages permit more convenient tightening and loosening of the boot straps. A strap/yoke configuration provides improved interconnection between the boot and the user's foot. The pull cord is routed within the sole of the boot and upward along the ankle area of the boot for more convenient access. The pull cord is connected to retract linkages at both heel and toe areas, both of those linkages being spring loaded to provide normally extended pins. A variety of pin receptacle configurations are shown for facilitating boot-to-binding step-in connection.

A substrate for use in a flooring system which has a subfloor and a decorative upper layer. The substrate is made in a continuous sheet which has a bottom surface, a top surface, side surfaces and end surfaces. The top surface and the oppositely facing bottom surface are essentially parallel to each other and are spaced apart by the thickness of the substrate. Voids are provided in the substrate, the voids are provided between particles of rubber or other similar material. When the substrate is positioned between the subfloor and the decorative top layer, the particles of rubber provide the strength required to prevent deformation of the substrate in the direction of the thickness and the voids contribute to the sound dampening characteristics required to provide decibel reduction across the thickness of the substrate.

The present invention describes a synthetic turf having super absorbent materials in order to keep the synthetic turf cooler than conventional synthetic turfs. The present invention also provides for synthetic turf infill cooling particles comprising a layer of water-absorbing material coating a foundation comprising a core substrate. In one embodiment, the cooling particle is comprised of a core particle or substrate, which is coated with a water-absorbing material. In one embodiment, the water-absorbing material is a super absorbent polymer.

A ladder strap (150) is made by joining—for example, by co-molding—a first, relatively supple material, defining a lower strap portion (155) with a second, relatively hard material defining an upper strap portion (165). The teeth (167) of the ladder strap are comprises substantially of the harder, second material. In a preferred embodiment, the first and second materials are thermoplastic urethanes, and the co-molding is done using an injection molding process. The co-molding process may be accomplished with co-injection, wherein the two materials are injected at about the same time, or the first material may be injected into a first mold cavity and allowed to partially set, after which the cavity is modified to accommodate the second material.

Selected patterns of lights are displayed on a recreational conveyance such as a snowboard according to the motion of the board. A selection of patterns is stored in a processor memory, the motion of the board is measured (for example with accelerometers) and a pattern is selected from memory based on the measured motion. Then lights on the board are blinked on and off in the selected pattern. Accelerometer inputs are analyzed and a series of states is derived for each accelerometer axis. A series of states can be analyzed as a set to select a different pattern. Also, the magnitude of the states (such as duration, speed, or intensity) may affect the pattern selected. The process may be adaptive, so that the analyzing step further analyzes user weight or past snowboarding style to set adaptive thresholds for selecting patterns.
