Method and system for actuating electro-mechanical ribbon elements in accordance to a data stream
First Claim
1. A method for actuating electro-mechanical ribbon elements suspended over a channel defining a bottom surface and having a bottom conductive layer formed below said bottom surface, the method comprising the steps of:
- providing a data stream;
generating in accordance to said data stream a modulated high frequency voltage signal; and
applying said modulated high frequency voltage signal to the ribbon elements.

Abstract
A method is disclosed for actuating electro-mechanical ribbon elements which are suspended over a channel. The channel defines a bottom surface and having a bottom conductive layer formed below said bottom surface. A data generator provides a data stream. The data generator is connected to a modulator. Additionally, an actuation voltage generator, connected to the modulator, produces a periodic high frequency voltage signal that has a frequency close to mechanical resonant frequency ƒR of the ribbon elements. The signal from the modulator is applied to the ribbon elements 31 of the electro-mechanical grating device.
