A lift system includes an overhead support, a counterweight, a base unit including a brake and secured to a floor, a fly line, and a load line. The fly line connects the counterweight, the overhead support, and the base unit via pulleys. The brake is configured to engage the fly line to limit movement of the counterweight and a load. A manual rope brake includes a housing having a base portion, an upper portion, and a hinge rotatably connecting the upper portion to the base portion. A cam lock is within the housing between pulleys. The cam lock engages a rope when the brake is engaged, and disengages from the rope when the brake is disengaged. A portable lift system includes a container configured to carry pulleys, a base unit, a fly line, and a load line when the lift system is in transport. Related methods are also disclosed.

A photography background mat that rolls up into a cylindrical shape making it easy to transport. The inventive device includes a top layer of woven fabric ideal for a photography background, two or more layers of woven fabric, and two or more layers of adhesive as required to bond all layers of woven fabric. The mat can also include a bottom layer of woven fabric ideal for a photography background, making the mat dual sided. When the user is finished photographing products on the present invention, the user simply rolls up the invention into a cylindrical shape without the mat wrinkling or collapsing into a fold.

A lift system comprises a drum that rotates about an axis, an elongate member that winds around the drum when the drum rotates in a first direction and that unwinds from the drum when the drum rotates in a second direction, a drive mechanism operable to rotate the drum, and a braking mechanism adapted to inhibit rotation of the drum. The braking mechanism includes a brake disk rotatable with the drum, a movable brake pad, and a ramp that guides movement of the movable brake pad. A method of operating the lift system comprises rotating the drum in a first direction to wind the elongate member onto the drum, rotating the drum in a second direction to unwind the elongate member from the drum, and moving the brake shoe along the ramp to thereby cause the movable brake pad to be compressed against the brake disk.

Described herein is a hoist fleet system including a head block and a guide fleet assembly. The head block includes a plurality sheaves having more than one diameter. The guide fleet assembly can be arranged proximate the head block such that an array of lift lines can be routed through the plurality of sheaves of the head block into the guide fleet assembly. The guide fleet assembly further includes a plurality of guide sheaves and a plurality of plates. The plurality of plates is configured to house the plurality of guide sheaves. The plurality of guide sheaves is positioned substantially orthogonal to the head block. The plurality of plates is further arranged such that the plurality of guide sheaves is arranged on more than one plane. The plurality of guide sheaves is configured to reduce the spacing of the lift lines.

In embodiments of the present invention improved capabilities are described for a computer-based method for reproducing an acoustic environment including accessing a computer stored multi-dimensional sound profile of a first space, wherein the multi-dimensional sound profile of the first space includes at least one multi-dimensional sound signature, the at least one multi-dimensional sound signature comprising a time-based sound reflection sequence within the first space for at least two sound parameters; and modifying a characteristic of an array of speakers in a second space to change the multi-dimensional sound profile in the second space to resemble at least one characteristic of the computer stored multi-dimensional sound profile of the first space.
