William E. Hewlett has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20010036003
    Abstract: 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.

  • Publication number: 20010030269
    Abstract: 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.

  • Patent number: 6288828
    Abstract: 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.

  • Patent number: 6261636
    Abstract: 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.

  • Patent number: 5900685
    Abstract: A noise-reduced stage lighting system has a motor having an output shaft driving a moving part of a stage lighting device, e.g. pan and tilt functions. An anti noise coupling is used to attenuate the noise produced by the assembly. An interface surface is formed with no metal connections between the noisy motor and the relatively quieter downstream components.

  • Patent number: 5426576
    Abstract: A color cross-fading system for a luminaire includes two filter disks or strips each provided with a multi-layer filter coating to provide a dichroic filter effect. In each case the thickness of the coating layers varies continuous along a gradient axis of the filter disk or strips. One disk acts predominantly as a long wave pass filter and the other act predominantly as a short wave pass filter, but each disk has an essentially "complex" characteristic enabling a very wide range of different colors to be obtained by cumulative subtractive filtering, by varying the positions of the two disks or strips relative to an optical axis.
