ALEXANDRIA, Va., June 16 -- United States Patent no. 12,656,652, issued on June 16, was assigned to ELSTAR DYNAMICS PATENTS B.V. (Rockanje, Netherlands).
"Asymmetric driving for optical modulator" was invented by Anatolie Mitioglu (Eindhoven, Netherlands) and Anthony John Slack (Lorgues, Netherlands).
According to the abstract* released by the U.S. Patent & Trademark Office: "Some embodiments are directed to an electrophoretic optical modulator with asymmetric electrode driving. Electric AC signals are applied to multiple electrodes on at least two substrates to obtain an electric field between the substrates. The amplitudes of the electric AC signals are modulated causing a low-electric field region to move with respect to the electrodes...
