Abstract

The present invention relates to variable optical transmission windows and window panels (VLTP) which are used for architectural applications such as building entryway systems and windows. The optical transmission of the VLTPs is reversibly changed by applying an electrical voltage. The emphasis is placed on doors which can be placed in the field without having certified technicians. The doors and windows having these VLTPs may also have other electronic devices which provide added user functionality.
