Abstract
A system and method are provided for forming body structures including energy filters/shutter components, including energy/light directing/scattering layers that are actively electrically switchable. The filters or components are operable between at least a first mode in which the layers, and thus the presentation of the shutter components, appear substantially transparent when viewed from an energy/light incident side, and a second mode in which the layers, and thus the presentation of the energy filters or shutter components, appear opaque to the incident energy impinging on the energy incident side. The differing modes are selectable by electrically energizing, differentially energizing and/or de-energizing electric fields in a vicinity of the energy scattering layers, including electric fields generated between a pair of transparent electrodes sandwiching an energy scattering layer. Refractive indices of transparent particles, and the transparent matrices in which the particles are fixed, are tunable according to the applied electric fields.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
