Patent number: 8314800Abstract: Three-digital micromirror devices (“DMD”) are used to alter the shape of light that is projected onto a stage. The DMDs each receive a primary color and selectively reflects some light of that color, thereby shaping the light that is projected onto the stage. The control for the alteration is controlled by an image. That image can be processed, thereby carrying out image processing effects on the shape of the light that is displayed. One preferred application follow the shape of the performer and illuminates the performer using a shape that adaptively follows the performer's image. This results in a shadowless follow spot.Type: GrantFiled: September 20, 2011Date of Patent: November 20, 2012Assignee: Production Resource Group Inc.Inventor: William E. Hewlett

Patent number: 8050777Abstract: Producing complicated effects based on image processing operations. The image processing operations are defined for a processor which may be different than the processor which is actually used. The processor that is actually used runs an interpreter that interprets the information into its own language, and then runs the image processing. The actual information is formed according to a plurality of layers which are combined in some way so that each layer can effect the layers below it. For example, the layers may add to, subtract from, or form transparency to the layer below it or make color filtering the layer below it. This enables many different effects computed and precompiled for a hypothetical processor, and a different processor can be used to combine and render those effects.Type: GrantFiled: November 21, 2008Date of Patent: November 1, 2011Assignee: Production Resource Group, Inc.Inventors: Mark A Hunt, Drew Findley

Patent number: 7835092Abstract: A flexible medium for a scrolling color changer and method of making thereof. The medium is made by applying an ink using a Meyer Rod which has varying cell lengths along its length. This leaves varying size cells of ink at different locations along the length of the medium. The ink has special characteristics whereby its evaporation rate and viscosity are carefully controlled. The viscosity is such that an amount of levelling will occur will be equal to the distance between any cells, but that cell to cell levelling will not, in general, occur.Type: GrantFiled: May 10, 2005Date of Patent: November 16, 2010Assignee: Production Resource Group, Inc.Inventor: William E. Hewlett

Patent number: 7761803Abstract: A system for designing light and sound systems for use in stage productions. Virtual reality interfaces facilitate the selection and location of lighting and sound displays by providing a real-time simulation of the devices and the display produced thereby. The system also calculates parameters with respect to structural elements used for mounting the lighting and sound equipment. In addition, the virtual reality interface permits the simulation of the packing of the lighting and sound equipment and the automatic calculation of parameters relating to packing space, package weight, preferred location, and order of packing.Type: GrantFiled: May 13, 2003Date of Patent: July 20, 2010Assignee: Production Resource Group, Inc.Inventors: Richard Parker, William Hewlett
