  • PROGRAMMABLE LIGHT BEAM SHAPE ALTERING DEVICE USING PROGRAMMABLE MICROMIRRORS
    Publication number: 20120075357
    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.

  • Moving Light Table
    Publication number: 20120069588
    Abstract: A moving light test system allows connecting moving lights to an interface board and conveying the lights and orienting and testing the lights while they are attached to the board. The lights can be mechanically and electrically connected to the board, and once connected, can be tested in multiple ways without reconfiguring or removing the lights. The board has a connector that can be plugged in at various locations, and the board can also be handled by mechanical devices. In this way, once the light is connected to the board, it does not need to be re-handled. In addition, lights can be tested in different orientations.

  • Gobo wheel location drive
    Patent number: 8132473
    Abstract: A gobo wheel with automatic detection system that automatically detects a rotational position of the gobo. The rotational position can be detected by a magnetic marking system. Each of the gobos can be randomly placed within the holder. The position of the gobos can be automatically determined during a start up routine for example, and then those positions can be stored and used for later determination of a position.

  • Gobo Virtual Machine
    Publication number: 20120046766
    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.

  • Programmable Light Beam Shape Altering Device Using Separate Programmable Micromirrors for Each Primary Color
    Publication number: 20120008325
    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.

  • Reduced complexity and blur technique for an electronic lighting system
    Patent number: 8077998
    Abstract: Digital blurring of an image is carried out by blurring using a linear or piecewise continuous blurring function. The blurring function blurs a rectangular portion of an image so that the blurring can be embodied by vertical blurring followed by halls on pull blow. Blurring is done by getting on portion of the line of pixels, adding and dividing by the number of pixels. All the columns are blurred, followed by all of the rows being blurred. The columns and rows can be blurred at the same time to maximize the number of cache hits.

  • Stage Lighting Lamp Unit and Stage Lighting System Including Such Unit
    Publication number: 20110299278
    Abstract: A stage lighting lamp unit includes a processor for receiving control data from a remote console. Beam orientation data for the lamp unit is passed to the lamp in the form of the x, y and z co-ordinates of a point in space through which the beam is to pass. The processor divides the required lamp travel into a number of stages dependent on execution duration data sent with the position data, and calculates, for each stage, a new value for pan and tilt angles for the lamp. These values are passed to pan and tilt controlling co-processors which control servo-motors for pan and tilt operation. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required. The shutters of all the lamps in a system can be instructed from the remote console to open and close in synchronism, thereby providing a stroboscopic effect.
