| Title: |
Application Independent Operational Controls of a Suspended Particle Device |
| Abstract: |
A scalable apparatus and a network environment dynamically changes the
light transparency of a single SPD device, a small number of SPD devices
or thousands of such SPD devices installed in windows in automobiles,
aircraft, trains, marine vehicles, residential homes, commercial
buildings and skyscrapers. A scalable apparatus and a network environment
dynamically changes the light transparency of a single SPD device or
thousands of such SPD devices in the presentation of a multi-media
special effects display. Textual messages, graphical images and simulated
motion effects are driven. Such scalable apparatus being capable of
driving and using several operational parameters of SPD materials such as
frequency range, AC voltage and temperature so as to provide fine control
of SPD characteristics such as switching speed and power consumption.
