Latest Patents
Brian Rosen holds a patent for a tri-state capacitance controlled keyswitch. This invention features a deformable concave electrode that is movable by an actuator toward and away from a pair of capacitor plates. The design allows for changes in the capacitive coupling between the capacitor plates. The electrode typically remains remote from the dielectric layer in a weak capacitance open circuit position. A first higher capacitance closed circuit position is achieved when the electrode is undeformed and in contact with the dielectric layer. The second highest capacitance closed circuit position occurs when the electrode is deformed and makes contact with the dielectric layer.
