Abstract: Described herein are systems and methods for controlling an illumination area as a function of time, location, or position. The systems and methods may generate illumination patterns having aesthetic effects or conveying information. In one example, a device for selectively controlling a projected illumination beam pattern of visible or non-visible illumination includes a mirror for receiving and reflecting light from an illumination source, where the mirror is operable to move in an oscillating motion, and a controller for generating time varying signals for causing the illumination source to vary a characteristic of the light (e.g., color, intensity, shape, or combinations thereof) from the illumination source and produce a predetermined illumination pattern.

Abstract: Described herein are methods, devices and systems for effective, adjustable wide-field illumination. In particular resonant engines for illuminating a broad area by resonant oscillation, and methods of moving at least one mirror at or near a resonance are described. A resonant engine includes one or more mirrors that may be oscillated to reflect light from a light source(s) to create a target illumination pattern. Devices and systems in which the mirror or mirrors are oscillated at an energy-efficient manner are described. Also described are optics, control features, and techniques that may be utilized to enhance the energy efficiency of the resonant engines and system described.

Abstract: The present invention discloses a power supply device, particularly for supplying a controlled electrical signal in an electrochemical process, e.g., plating, etching, etc. The power delivery device provides an electrical signal with optimal characteristics and setting for processing one or more surfaces in an electrochemical process. The power delivery device comprises a power stage having an input for receiving a power signal and an output being operably connected to the object. A sensor is operably connected to the output. A controller is operably connected to the output and responsive to the sensor. A modulator is operably connected between the controller and the power stage wherein the power stage outputs the electrical signal to the object in response to the modulator and the controller.
