Abstract: A self-cooling artificial turf system for water retention and evaporation is described. The system includes a synthetic surface comprising an elastic sub-layer having shock absorbing pads, or shock pads, configured to interlock to one another. Individual ones of the shock pads comprise a top surface and a moisture accumulation region defined by an edge having a height taller than the top surface. Synthetic fibers are positioned above the synthetic surface that are in fluid connection with the at least one moisture accumulation region such that the synthetic fibers are able to wick moisture from the at least one moisture accumulation region when the moisture is present. At least a portion of the synthetic fibers are hydrophilic such that the synthetic fibers wick the moisture as it is expelled from the at least one moisture accumulation region, thereby cooling at least the portion of the synthetic surface.

Abstract: A panel assembly is designed to be installed adjacent each other comprising surface covering panels and joining padding layer panels. Surface covering panels comprises padding layer panels made of a first material, a sheet member affixed to the padding layer panel comprising edges extending beyond the padding layer panel; and a first component of a fastening element affixed to the edges. Joining padding layer panels comprise a body made of a second material different to the first material; and a second component of the fastening element affixed to the top surface of the joining padding layer. The components of the fastening element are adapted to interface with each other such as releasably attaching joining padding layer panels to the edges of adjacent surface covering panels, and maintain fastening of the adjacent surface covering panels when undergoing thermal expansion resulting in shear displacement of the components of the fastening element.

Abstract: A watercraft comprises a hull, a deck disposed on the hull, a motor connected to at least one of the hull and the deck, a propulsion system operatively connected to the motor, a command console disposed on the deck and operatively connected to the motor, an accelerator control lever operatively connected to the command console, and a control unit operatively connected to the command console and to the motor. The control unit receives, from the command console, a value representing a current position of the accelerator control lever, controls an operating parameter of the motor based at least in part on the current position of the accelerator control lever, receives, from the command console, a cruise control enabling signal, and in response to receiving the cruise control enabling signal, selectively engages a cruise control function of the watercraft by maintaining the operating parameter of the motor.

Abstract: There is described a panel assembly to be laid over a base surface and under a carpet-like top layer to install a multi-layered sports-playing field. The padding assembly comprises a panel comprising a top face and a bottom face, with the top face of the panel facing the carpet-like top layer and the panel further comprising drainage holes fluidly connecting the top face to the bottom face. The padding assembly also comprises a drain mat affixed to the bottom face of the panel with the drain mat operating as a fluid-permeable layer distancing the bottom face from the base surface. A method of installing a multi-layered sports-playing field is also described.

Abstract: A trim system for a watercraft has a nozzle pivotable about a trim axis, a trim actuator operatively connected to the nozzle, at least one sensor for sensing at least one operating condition of the watercraft, a control unit electronically connected to the at least one sensor for receiving a sensor input signal indicative of the at least one operating condition. In a first trim control mode, the control unit controls the trim actuator to pivot the nozzle about the trim axis within a first range of trim angles. In a second trim control mode, the control unit controls the trim actuator to pivot the nozzle about the trim axis within a second range of trim angles. The first range of trim angles is greater than the second range of trim angles. A watercraft having a trim system and a method of controlling the trim are also disclosed.

Abstract: An artificial turf system is for installation over a receiving surface. The artificial turf system comprises a flexible sheet member to be laid over the receiving surface via its lower surface. It comprises first yarns having a first melting point; second yarns, distinct from the first yarns and having a second melting point; and third yarns, having a third melting point, with all yarns extending upwardly from the upper surface of the sheet member. The third melting point is lower than the first and second melting point. The artificial turf system undergoes a heat treatment at a temperature higher that the third melting point prior to installation through which third yarns at least partially fuse with part of one of the first yarns and the second yarns. Further described is a method of manufacturing the artificial turf system.
