The latching switch utilizes an electrorheologic fluid and the electronic latch function thereof is actuated by a pressure signal and deactivated by the removal of both the pressure signal and a holding voltage.

Abstract: A reflective display system is disclosed that utilizes four overlapping layers of colored dye injected into channels so as to provide a pixel assembly operatively responsive to present an image for human viewing. Each of the four layers contains one color of the CMYK color method. The reflective display system injects packets of colored liquid or transparent fluid into the channels made of transparent material and each channel carries one of the colored liquids. Each of the pixel assemblies is defined by the width of the channel in one direction and the size of the liquid colored packet within the channel in the orthogonal direction. The color of the pixel is defined by the stacking of the liquid dyed colored packets at a particular location when viewed against a white substrate.
