Handheld, multi-axis camera stabilization device utilizing MEMS gyro sensors

(U.S. Patent 7,642,741, additional patent pending)

In the field of motion picture photography, camera stabilization devices are used to isolate the camera from the natural body movements of the operator, while providing fluid maneuverability across a set. The purpose of this project is to design, build and optimize a low cost, compact gyro-based servo stabilization device for a professional handheld motion picture camera.

This device uses MEMS based rate gyro sensors mounted to a gimbaled camera rig to measure the angular rate of the camera’s rotation. The gyro signals are amplified to drive DC servo motors coupled to the camera’s rotational axes. As a gyro measures the cameras rotation about an axis, the corresponding servo motor applies an opposing torque on the platform to oppose camera rotation.

The camera is mounted to a yaw and pitch gimbaled structure, adjustable so that the rotational axes can run through the cameras center of mass, thus minimizing the torque and power required to stabilize the camera.

Each gyro rate signal is amplified by a proportional gain amplifier. An integrator circuit acting on each rate signal, helps ensure that the rig does not drift due to extraneous forces. A pair of high current, high power operational amplifiers drive each servo motor from the sum of the proportional and integrated rate signals.

Dynamic tests confirm that the gyro stabilization dramatically and consistently decreases the peak yaw rotation and peak pitch rotation relative to the clamped configuration. Further enhancements include the addition of a third axis and the use of geared motors. Experimental results are validated with a MATLAB/Simulink simulation.

Threellop Nanotechnology – Inorganic Chromosome Based in Silicon.
The component or electrical circuit, Inorganic Chromosome Based in Silicon (InChroSil) emulate the computational behavior and information treatment way like the organic DNA do it, but from the artificial perspective and using silicon, not emulating the chemical reactions of the organic DNA, because the integrated circuit only reproduce the DNA structure and information, conforming an artificial DNA made with silicon, usual for the construction of integrated circuits (chips).

laser tv (without MEMS) radar printer projector camera

admin — Tue, 09 Dec 2008 14:01:14 +0000

This scanning video technique is quite different from LCD projectors. 25 frames of real-time pictures per second can be performed on any screen by a 0.1 mW laser pointer without MEMS. Beam is modulated with playstation video signal and scanned with mirrors. Horizontal scanning freq. 15625Hz; Vertical scanning freq. 50Hz.
Colour video is possible with RGB laser. Dimensions of the picture increases with distance and limited only by the capacity of the laser source.
Fields of application: Video monitoring (TV,cinema, etc.), large scale projections (advertisement, home cinema, projectors,disco lights); printers without toner; fast scanning data recorders (CD,DVD, etc. without motors); receiving systems (scanner, camera, detector, radar… replacing the laser with a photomultiplier), and many other real-time, real-space scientific, medical, commercial, industrial, military applications of scanning radiation.
