METHODS OF SWITCHING AND APPARATUS COMPRISING AN ELECTRICALLY ACTUATED VARIABLE TRANSMISSION MATERIAL
First Claim
1. A method of switching an electrically actuated variable transmission layer, the layer being between a first electrode and a second electrode, wherein a sufficiently high frequency alternating electric field is applied between the first and second electrodes such that a selective region of the layer in between the first and second electrodes is switched.

Abstract
A method of switching an electrically actuated variable transmission layer is disclosed. The layer is between a first electrode and a second electrode, and when a sufficiently high frequency alternating electric field is applied between the first and second electrodes, a selective region of the layer in between the first and second electrodes is switched. Apparatus for use as a glazing pane having a sheet of glazing material and an electrically actuated variable transmission layer facing the sheet of glazing material is also disclosed. The layer is sandwiched between a first electrode and a second electrode. There is an electric field generator in electrical communication with the electrodes and being configured to produce an alternating electric field of sufficient strength and of a sufficiently high frequency to switch a selected region of the layer in between the first and second electrodes.
