| 20120025157 | LIFT ASSEMBLY, SYSTEM, AND METHOD - A lift assembly comprising a plurality of elongate members (e.g., cables) positioned for movement in a longitudinal direction, a drive mechanism (e.g., a drum) coupled to move the elongate members in the longitudinal direction, and a loft block including a sheave located to redirect at least one of the elongate members to a non-parallel path that is not parallel to the longitudinal direction, wherein a remainder of the elongate members travel along a parallel path that is above the sheave. The loft block can include an idler bar having an upper surface that is higher than an upper surface of the sheave. For example, the idler bar can be positioned directly above the sheave. | 02-02-2012 |
| 20110270437 | PERFORMANCE VENUE WITH DYNAMIC MECHANICAL LOAD MANAGEMENT SYSTEM AND METHOD - A performance venue having a dynamic load management system for use in managing loads. The system uses a dead man circuit as a means for determining the actual or anticipated dynamic load produced by moving loads, and then disables the system by opening the dead man circuit when too many loads are moved or selected to be moved. Preferably, the invention is embodied in a dead man circuit is pure hardware, and is free of software components. The invention also provides a method of controlling movement of loads in a performance venue having a plurality machines. In its basic form, the method comprises selecting at least one of the machines for movement, closing a dead man circuit, and opening the dead man circuit if the current in the dead man circuit falls outside a predetermined range. | 11-03-2011 |
| 20100301292 | LIFT ASSEMBLY, SYSTEM, AND METHOD - A lift assembly system and method can include a substantially rectangular tube, a motor operably connected to first and second traction drives and a rotatable drum and structurally connected to one end of the tube, a head block fixed to the opposite end of the tube, and a plurality of loft blocks positionable at an infinite number of locations within the tube. An elongate member attached on one end to the drum can be routed through a generally horizontal path from the drum to the first and second traction drives, the head block, and the loft blocks, and then through a generally vertical path from the loft block to an attached article. The elongate member can be wound about the drum to raise the article, and unwound from the drum to lower the article. The system can further include a load-side braking mechanism. The tube can include a compressible material adapted to absorb at least a portion of a horizontal load placed on the lift system. | 12-02-2010 |
| 20100171444 | Colorizer and method of operating the same - Systems and methods for controlling the output of a plurality of light sources. The system can include four or more light sources (e.g. light emitting diodes (“LEDs”)) and a controller. The light sources are included in, for example, a luminaire. The respective outputs of the plurality of light sources are controlled using a hue and purity (“HP”) control technique. The HP technique includes selecting a dominant hue (e.g., green, blue, red, etc.). The purity of the selected hue is then modified to include or remove wavelengths of light adjacent to the selected hue. For example, if the selected hue is green, gradually reducing the purity of the selected hue gradually increases the presence of cyan and amber in the output of the luminaire. As the purity is reduced further, additional wavelengths of light are included, but the output of the luminaire remains, in essence, green. | 07-08-2010 |
