A combined lifting burn fencing equipment is disclosed herein. The combined lifting barn fencing equipment includes a barn movably mounted in a first annular groove in the periphery of stage, a lifting mechanism that drives the barn to lift up and down, a fence movably mounted in a second annular groove of the barn, and a hoisting mechanism that drives the fence to lift up and down. The lifting mechanism is mounted at the bottom of the first annular groove. The hoisting mechanism is mounted at the top of the gate above the stage. The barn is mounted a bedplate. The barn descends to the first annular groove or rises to the above of the stage driven by the lifting mechanism.

Exemplary air amplifiers described herein can utilize a high-pressure stream of gas to accelerate a low-velocity stream of gas to provide a high-velocity, high-volume stream of gas. This high-velocity, high-volume stream of gas can generate unwanted noise as the high-velocity, high-volume stream of gas propagates through the air amplifier. The exemplary air amplifiers described herein can passively and/or actively suppress, for example, diminish, re-tune, or even completely cancel, the unwanted noise as the high-velocity, high-volume stream of gas propagates through these exemplary air amplifiers. The exemplary air amplifiers described herein can include one or more absorption materials to passively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The exemplary air amplifiers described herein can generate multiple noise suppression waves to actively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The multiple noise suppression waves can destructively combine with the unwanted noise generated by the high-velocity, high-volume stream of gas to suppress the unwanted noise.

One example embodiment includes a mobile action sports ramp. The mobile action sports ramp includes an incline portion connected to a vehicle portion by a hinge. The incline portion includes a lower incline portion connected to an upper incline portion by a hinge. The lower incline portion folds onto the upper incline portion and the incline portion then rests upon the vehicle portion when the mobile action sports ramp is collapsed and capable of transportation. The lower incline portion unfolds into alignment with the upper incline portion and the incline portion then raises up when the mobile action sports ramp is erected and capable of use in various action sports. Methods for erecting and collapsing a mobile action sports ramp are also provided.

A wire rope tension grid is a walking surface comprised of interwoven wire rope. The wire rope is supported by a framework of steel angle and tubing. The framework is supported by mounts that are hung from the support beams in the ceiling of a structure, often a performing art center, a television studio, a black box theater, museum dioramas, theme park scenes, live animal pens, or other entertainment venues. These grids are not intended for public usage, but rather are intended for operation staff. New improvements to these grids are listed in this document.

Apparatuses, systems, methods, and computer program products are presented for competitive escape rooms. A first room has a predetermined method to accomplish a task within the first room. A second room has a same predetermined method to accomplish a same task within the second room as in a first room. A hardware controller device determines in which of a first room and a second room a task is completed first by one of a plurality of competing sets of users.

The present invention is pool or billiard table having a system of multiple local section, wedge leveling devices secured in recesses in a support frame, which allow a user to precisely and in very small increments adjust sectionwise leveling of a slate slab.
