Abstract: The principles described herein provide floor tiles and modular floors. The floor tiles may include small steps in a surface structure to increase traction. The floor tiles may also or alternatively include diagonal cross ribs to block the passage of debris and break liquid surface tension. The modular tiles may be injection molded. The floor tiles may also provide multiple layers of traction, providing more sure footing than previous flooring systems. The floor tiles may provide multiple layers of traction, providing more sure footing than previous flooring systems.

Abstract: The present specification describes sporting equipment methods and apparatus that may be used for ball play, and may be particularly useful for ball rebounding. One aspect of the novel sporting equipment described herein relates to the adjustability of a rebounder. Rebounders or rebound systems in accordance with principles of the present invention are strong, durable, and also adjustable. An adjustment mechanism in accordance with principles of the present invention may permit a user to change the angle of the rebound system to change the trajectory of rebounded balls to suit the needs of various players and situations. In contrast, conventional rebounders tend to be small, flimsy and are not adjustable.

Abstract: The present specification describes sporting equipment methods and apparatus that may be used for basketball, and may be particularly useful for height adjustment. One aspect of the novel basketball standard relates to a mechanism for adjusting the height of the basketball hoop. The adjustment mechanism may be cable driven, and all or most of the adjustment mechanism may be located internal to a support pole of the basketball standard. In contrast, conventional adjustable basketball standards are not cable driven and often include many exposed moving parts.

Abstract: The principles described herein provide floor tiles and modular floors. Some embodiments of the floor tiles and modular floors include multiple levels of support. One of the levels of support may be a resilient level that compresses comfortably under a load. Another level of support may include a generally rigid level that supports the floor or tile after the resilient level has compressed a predetermined distance. One embodiment includes a third generally rigid level of support that supports the floor or tile under certain loads. Some embodiments of the floor tiles include inserts for increased traction. The inserts may be removable and protrude from a top surface and/or a bottom plane of the floor tiles. The tiles may include a locking system that allows adjacent tiles to interlock, while also permitting a predetermined amount of lateral sliding relative to one another. The modular tiles may be injection molded and the inserts and the resilient support level may comprise an elastomer.

Abstract: The present invention provides floor tiles and modular floors. The floor tiles may include a locking system that allows adjacent tiles to interlock, while also permitting a predetermined amount of lateral sliding relative to one another. The modular tiles may be injection molded, and a minor change in the mold facilitates variation to the amount of lateral slide allowed between interlocked tiles. The floor tiles may also provide three layers of traction, providing more sure footing than previous flooring systems. In addition, the floor tiles may comprise a two-tier suspension system that yields a flex or spring-like effect.

The floor tiles may also provide four layers of traction, providing more sure footing than previous flooring systems.

Abstract: The present invention provides a method of making modular floor tiles. The method includes adding a protective layer to a modular floor tile, which may provide surface protection, a high gloss finish, or other advantageous features. The protective layer may comprise a polymer sheet that is melded to a top surface of the modular floor tile.

Abstract: The present invention provides a modular flooring system including a ramp to facilitate entry and exit from the flooring system. The ramp may be modular and interconnect with all or parts of a perimeter of the flooring system, and the ramp may also interconnect with adjacent ramp members.

Abstract: An EMI transfer fitting suitable for use in submarines and other harsh environments is provided. In one embodiment, the EMI transfer fitting has two couplers, that collectively provide a mechanically robust interconnection between a flexible conduit (through which a bundle of data cables is encased by a wire mesh sheath that provides EMI shielding), and a rigid conduit made from a metallic material that requires no separate wire mesh sheath to provide EMI shielding. In addition to providing a robust mechanical interconnection, the transfer fitting provides a robust and seamless EMI shielding between the flexible conduit and the rigid conduit.
