Abstract: Deployable slackline systems are disclosed which can support a slackline at a desired height and nominal tension. The disclosed systems may maintain one or more slacklines and can adjust height and tension of individual slacklines while the slacklines are in use. The disclosed slackline systems are stowable; tensioning and termination assemblies of the slackline system can each fold into a compact housing having a height substantially less than a vertical range of motion of the slackline. The disclosed slackline systems can be implemented in aquatic or non-aquatic performance environments such as on cruise ships or other hospitality settings.

Abstract: Systems and methods for firework water illusions are disclosed. In one aspect, a device for creating an illusion of rotary pyrotechnics includes at least one nozzle configured to rotate about an axis of the device and spray water in a radial direction while rotating. The device can also include a water supply configured to provide the water to the at least one nozzle and a lighting system configured to illuminate the water sprayed from the at least one nozzle to create an illusion of rotary pyrotechnics.

Abstract: Provided is a winch apparatus including two exchangeable and interchangeable gears connecting a motor to a drum, the drum being operative to extend and retract a flexible line. By exchanging and interchanging the gears to effect a change in the ratio of the diameters of the first gear to the second gear, the torque and the linear speed of the flexible line are adjustable, permitting the same winch apparatus to move heavier loads at lower speeds, or lighter loads at higher speeds.

Abstract: A lifting device includes a housing movably securable to a support structure extending along a predetermined path corresponding to a portion of the support structure. The housing includes a motorized lifting machine movable with the housing. The housing includes an engagement device movable with the housing, the engagement device operably engaging the portion of the support structure to move the housing.
