Rate of deceleration is an important factor in determining the severity of injuries, such as head and neck injuries, possibly sustained when participants collide with a wall assembly while playing, for example, ice hockey. The described wall assemblies each include a support assembly and a movable wall assembly supported by and movable with respect to the support assembly. Telescoping parts of the movable wall assembly enable deflection of the movable wall assembly to complex angles with respect to the support assembly. In addition, movable wall assemblies can be couple such that impact on one wall assembly can cause deflection of an adjacent wall assembly. Covers, shields, and spacers can be positioned to decrease gap formation during deflection of the movable wall assembly to reduce the risk of pinch points.

A resistance mechanism for an exercising device is provided. In one embodiment, the resistance mechanism comprises at least one flywheel. The resistance mechanism may also comprise at least one resistance index wedge configured to engage with the at least one flywheel. The resistance mechanism may also comprise a resistance adjustment mechanism connected to the resistance index wedge and configured to alter a resistance provided to the exercise device by increasing pressure provided by the at least one resistance index wedge to the at least one fly wheel assembly, wherein the resistance mechanism is configured to operate in an outdoor environment.

A ball net structure arranged to be portable, collapsible, and able to be configured into different arrangements for different nets and/or different sports-related activities. The ball net structure comprising a base structure including at least one support portion, at least one base extension, and at least one base extension hinge, wherein the at least one support portion and the at least one base extension are coupled to the at least one base extension hinge. At least one rod is removably coupled to the base structure and received by a net, wherein the net is adapted to exert a force on the at least one rod causing the at least one rod to exert a force onto said base structure.

The present invention comprises a unique system and method for providing adaptable ball delivery and tracking, including appropriate sensor hardware, interactive gameplay user interfaces and point of sales systems. The system and method of the present invention are especially relevant to baseball and softball as, among other components, the system comprises a vertical, ground-up soft toss ball delivery mechanism, automated player and ball-tracking devices, and ball-collection and transport systems. The ball collection and return components eliminate the need for “fielders” and enable the creation of the first “batting range”. The vertical, ground-up soft-toss pitch machine further enables the first multi-story batting facility with player batting bays that open onto a sports field. Further, certain embodiments of the present invention integrate hitting screens, augmented reality display and simultaneous coordination of gameplay and communication between players, regardless of the players' physical location.

An exercise device comprising; a platform, a first limb attachment means, a first extendable cord attached to the first limb attachment means, the first extendable cord being at least partially located within the platform, and a tensioning means within the platform, wherein the tensioning means can be adjusted to alter the resistance of the first extendable cord to extension.

The mobile sheet flow water ride apparatus of the present invention utilizes a rigid inclined structure. Ride surfaces, aisle surfaces, and surround fences are covered with protective inflatable air cushions. The ride apparatus of the present invention has non-retractable transport wheels and uses a multitude of adjustable jacks to take the load off the transport wheels and support the ride apparatus. The ride apparatus utilizes a 15,000 gpm double-suction pump driven by a 460-horsepower diesel engine that is transported in its own trailer. Water is pumped from a main storage tank through a horizontally-oriented nozzle that 2.438 meters wide and 6.35 cm high at supercritical speed. The water rushes up the slope, over a berm at the top of the slope, and back into the main storage tank through a square main return grate.

A trampoline anchor comprising a trampoline frame, a trampoline bed attached to the trampoline frame, trampoline springs connecting the trampoline frame to the trampoline bed, a fluid chamber formed as a toroidial enclosure, and an outside skirt attached to the fluid chamber, wherein the outside skirt connects between the fluid chamber and the trampoline frame at a fluid chamber skirt connection. The trampoline anchor can also have fluid chamber pods attached to the legs of the trampoline.
