Abstract: Self-supporting structures are assembled from hollow construction members, particularly inflatable balls made of a durable resilient material.

Abstract: A play swing system includes a safety harness attached to each seat, as well as other features for interactive and competitive throwing and tossing games. The safety harness may incorporates various games features, and thus encourage use in activities that require at least one free hand, or otherwise increase the risk of slippage and falling from the play swing seat. Various embodiments accommodate as well as challenge the spatial perception, dexterity and reflexes of players of different ages. For examples, younger players might compete by throwing objects at a fixed target mounted on the ground. In other embodiments, the target is moving in synchronization with the oscillatory motion of the adjacent players swing by a physical coupling or attachment. Interactive play is encouraged at the higher skill levels by configuring the targets associated with adjacent seats to face each other.

Abstract: A method is provided for a method of purchasing goods online, which allows end users to receive money in return for browsing the internet and making purchases. According to the features of the invention, the end user enters a profile into YOUniverse, which is uploaded to the database. The user then logs in to search for items and the advertisement search results are specific to the end user's profile. The user controls the amount of information in their profile; however, more information yields better advertisement results and more money.

Abstract: A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided by a support system of independent poles. Variable placement net fasteners also are detailed.

Abstract: A trampoline provides higher performance and greater shock absorption capability by utilizing pairs of springs to connect the rebounding mat to the supporting frame. The springs in each pair are coupled to a common junction on the periphery of the rebounding mat, being disposed vertically with respect to each other. The upper spring in each pair is directly connected to the rebounding mat and the trampoline frame to initially to tension the mat in the equilibrium position. The lower spring in each pair is coupled to the frame and then to rebounding mat via a linkage arm such that it comes substantially under tension only as the corresponding upper spring is stretched. Depending on the level of impact force on the trampoline mat both springs extend, such that their combined stored energy propels the user upward on the return bounce. However, as each spring pair engages in stages the shock of the users initially landing is gradually absorbed.

Abstract: A smart traffic control device transmits information to approaching vehicles regarding its current and future state enabling vehicles to control their speed to avoid arriving at the traffic control device until it permits the passage of traffic, thus avoiding stopping, idling and reaccelerating when reaching the traffic control device. In other embodiments the traffic control device or systems receives information from vehicles, transmitting it to other vehicles.

Abstract: A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided by a support system of independent poles, linked at their tops by a flexible strap or line which is attached directly to a protective cap at the top of each pole. Also disclosed are a method and apparatus for attaching a pad to a trampoline frame either with or without an enclosure.

Abstract: A hopping play ball has one or more water reservoirs in fluid communication with one or more squirt nozzles. The squirt nozzles are activated by a user.

Abstract: A rebounder comprising an encompassing frame has a platform suspended on the frame. The platform has a substantially rigid base and a pad of resilient material is secured on the base. A vertical handhold frame may have a directly attached handhold or a rotating handhold, which may be attached by elastic connections.

Abstract: A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided in the preferred embodiment by a support system of independent poles, linked at their tops by a flexible strap or line. The trampoline may include a tubular frame supported by a plurality of legs with brackets securing the legs to the frame tube without welds. The trampoline may also include an electronic accessory that is activated or that produces an electrical signal as a result of jumping on the trampoline.
