Patent number: 8976441Abstract: A digital micromirror device (“DMD”) is used to alter the shape of light that is projected onto a stage. The DMD selectively reflects some light, 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 follows 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: August 29, 2011Date of Patent: March 10, 2015Assignee: Production Resource Group, LLCInventor: William E. Hewlett

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: 7900882Abstract: A hook clamp has surfaces allowing the clamp to be placed on a support and clamped thereto. The surfaces are such that the clamp can be placed on the support and its weight held by the support prior to tightening. The clamp has a built-in connector for supplying power to the lamp. The clamp has one or more fail-safe holes for securing the clamp to the support with a safety cable. The clamp also has one or more flanges that can be received by a separate mounting bracket, for mounting the clamp and any attached element during storage, staging, or when otherwise not being used.Type: GrantFiled: October 7, 2003Date of Patent: March 8, 2011Assignee: Production Resource Group, LLCInventors: Nigel Evans, William E. Hewlett

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.

Patent number: 7572035Abstract: An illumination obscurement device for controlling the obscurement of illumination from a light source which is optimized for use with a rectangular, arrayed, selective reflection device. In a preferred embodiment, a rotatable shutter with three positions is placed between a light source and a DMD. The first position of the shutter is a mask, preferably an out of focus circle. This out of focus circle creates a circular mask and changes any unwanted dim reflection to a circular shape. The second position of the shutter is completely open, allowing substantially all the light to pass. The third position of the shutter is completely closed, blocking substantially all the light from passing. By controlling the penumbra illumination surrounding the desired illumination, DMDs can be used in illumination devices without creating undesirable rectangular penumbras.Type: GrantFiled: September 28, 2007Date of Patent: August 11, 2009Inventors: William E. Hewlett, Nigel Evans

Patent number: 7078869Abstract: A lighting system with a digital micromirror device which forms a digital godo system that is controllable on a pixel level. The device includes a number of sensitive electronic elements. The device is controlled by two different controllers: a digital signal processor which is effectively the number crunching portion, and a controller, which controls the functions of the light. The controller also logs errors into a registery, such as a non-volatile memory. A field programmable gate array is used for a number of purposes, including to form the ports. One of those ports is a tech port, which is used to detect status of the light such as faults.Type: GrantFiled: September 8, 2003Date of Patent: July 18, 2006Assignee: Production Resource Group, LLCInventors: Michael Hughes, William E.
