Abstract: A hoist brake system is disclosed. The brake system incorporates an electro-mechanical device that acts as a fail-safe stopping mechanism for a hoist and has a default engaged. This allows the brake system to quickly and safely stop a device when power is lost, an emergency signal is provided or any other fault condition and be completely self-contained within the hoist itself.

Abstract: An innovative light fixture for use with acoustical shells is disclosed. The fixture incorporates a dome gimbal to allow rotation front-to-back and left-right around a horizontal axis and a third axis of rotation around a vertical axis. The dome configuration allows for a low profile and toolless adjustment allows stage side aiming by hand.

Abstract: A motorized acoustical banner that functions as a variable acoustic absorber is disclosed. The motorized acoustical banner includes a multi-panel fabric banner that allows for adjustable spacing between the layers of fabric as well as between the banner and the wall to which it is mounted. The motorized acoustical banner further includes a drum roller configuration that allows for easily and quickly changing the banner fabric without having to disassemble the entire device. The motorized acoustical banner also includes a tubular motor that can be removed from the device without removing the entire drum.

Abstract: A tunable acoustic panel that functions as an acoustic diffuser and absorber is disclosed. The acoustic properties of the tunable acoustic panel can be quickly and conveniently modified by moving a handle. The tunable acoustic panel is wall-mountable for use as an acoustical room treatment to selectively vary the acoustical response of a room or performance space.

Abstract: A conductor system includes a music stand and at least one support rack. The music stand and the support rack can be used independently, but can provide additional stability when coupled to each other. The podium and the rack can be positioned to accommodate the preferences of a user, including by height, radial, lateral, and pitch/tilt adjustments. The support rack is adapted to receive any number of user instruments, such as, for example, a laptop or an electronic keyboard. The podium and the rack can be transported without being lifted completely off the support surface.

Abstract: A portable staging system adjustable for quick assembly and disassembly and inherent sturdiness. The portable staging system includes a bracket assembly for detachably coupling a support member to the platform of the portable stage. The bracket assembly includes a bracket sleeve adapted to receive the support member, a brace member shiftable within the bracket sleeve between a support member engaging position and a support member clearing position, and an actuator assembly for simultaneously shift first and second drivers of the brace member.

Abstract: A convertible instrument rack includes a frame and multiple yoke sets. The frame includes support members and the yoke sets each include at least three yoke members which are each placed on a respective one of the support members. The respective position of the support members can be selectively shifted on the frame and the yoke members can be selectively shifted along their respective support member to accommodate tubas or sousaphones, as well as tubas or sousaphones of different sizes.

Abstract: A convertible percussion cart-platform system includes first and second instrument platforms that are shiftable between a transportation position and a performance position for moving and positioning musical instruments and a player platform that is shiftable between folded and unfolded positions for allowing a user to perform on instruments supported by first and second instrument platforms in the performance position.

Abstract: A hanger retainer for securing hangers to a garment-supporting rod. The hanger retainer generally includes first and second side portions spaced apart from each other, a hooked portion extending from at least one of the side portions, and first and second retaining portions extending between the side portions. The hooked portion is designed to hook around a garment-supporting rod such that the first retaining portion is spaced a first distance from the rod, and the second retaining portion is spaced a second distance less than the first distance from the rod. The hanger retainer is rotated about the rod from a first position in which a hanger is received between the side portions on the hanger rod, and a second position in which the hanger is secured to the rod, thereby enabling transport one or more hangers on the rod without concern that the hangers may fall from the rod.

Abstract: An all-terrain retail merchandising unit or kiosk that can be used outdoors and across grass and gravel for outdoor events. The all-terrain retail merchandising unit can include a chassis, pneumatic tires, and steering that can provide the all-terrain retail merchandising unit with mobility across grass, gravel, and any other uneven or non-flat surfaces. The all-terrain retail merchandising unit can be used inside facilities, moved across a campus, shifted from place-to-place during indoor or outdoor events, and loaded on trucks or trailers for away events.

Abstract: The present invention is an acoustic cabinet for the storage of musical instruments. Acoustic cabinet can have a storage portion having a plurality of individual storage units contained therein. One or more grill doors can cover the open end of acoustic cabinet. The size, shape, and arrangement of grill bars of door can be configured to reduce the effect of resonance. Rear panel of acoustic cabinet can include one or more sound-absorbing panels that absorb sound as it passes through acoustic cabinet. A protective backing can also be disposed between sound-absorbing panels and individual storage spaces to protect the panels from damage when instruments and other objects are inserted into the storage spaces. A combination of a grill door and sound-absorbing panels can allow acoustic cabinet to have a net-absorptive effect on a rehearsal room. One or more acoustic cabinets can be strategically positioned throughout a rehearsal room for optimal acoustic performance.

Abstract: A modular floor including a pair of main beams, at least one cross beam and a floor panel. The pair of main beams each has an attachment structure. The attachment structure includes a first support section, a second support section and a channel that extends between the first and second support sections. The first and second support sections have a convex upper surface. The at least one cross beam engages the main beams to retain the main beams in a stationary position with respect to each other. The floor panel has ends that each have a recess that is shaped complementary to the upper surfaces of the first and second sections.

Abstract: An electroacoustic shell system adapted create a performance area where sound created by a performer is received, processed, and returned to the performer in the performance area. The system broadly includes an electroacoustic shell with a vertical panel and a canopy, a microphone and a speaker operably coupled to the shell, and an electronics processing assembly connected to the microphones and speakers for recording, broadcasting, and simulating sound.
