Abstract: A water slide for a recreational pool or other body of water, the water slide being in a spiral configuration with a runway or flume down the spiral and into the pool. The water slide also includes a fountain, which may be centrally located within the spiral slide flume, that produces an upward and outward water spray pattern with an outer envelope that may be sized to correspond to an outer diameter or given outer extent of the spiral slide flume such that the water spray from the fountain falls substantially onto the water slide runway as opposed to on the pool deck.

Abstract: A pool safety sensing system to attempt to reduce the likelihood of drowning visually observes a zone with a camera, and if detected motion occurs, and alarm is generated. The alarm can be visible, audible, text based (email, with or without attached images, instant message) or telephonic. Alarm events can be stored for future reference. Zones of sensing or zones to ignore when monitoring may be defined in the field of view of the camera. Motion thresholds, such as size of moving object, speed of movement, can be employed to adapt to particular location requirements and types of sensing.

Abstract: An anchor for a rectangular tube employs a wedge assembly, whereby rotation of an adjustment bolt of the wedge assembly moves an upper and lower wedge member together, and the wedge engagement with a central wedge member causes said central wedge member to move toward engagement with the tube, thereby securing the tube within a base body. Clevis pins and corresponding key hole slots mount the wedge assembly to a base, while allowing easy removal of the wedge when desired.

Abstract: A rail for a swimming pool or the like is provided with an exterior polymeric coating over the metal rail, enhancing wet traction, providing electrical isolation, and coolness to the touch feel.
