  • Patent number: 7515367
    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: 7495817
    Abstract: A special record format used for commanding light pattern shapes and addressable light pattern shape generator. The command format includes a first part which commands a specified gobo and second parts which command the characteristics of that gobo. The gobo is formed by making a default gobo based on the type and modifying that default gobo to fit the characteristics.

  • Patent number: 7457670
    Abstract: 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.

  • Patent number: 7078869
    Abstract: 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.
