Insulated glazing units with memory modules

An insulated glazing unit, comprising:

• a frame;
• at least two partially or totally transparent panes associated with the frame to define a gap;
• a box arranged proximate to an upper portion of the frame and in side the gap;
• screening means inserted in the gap and adapted to alternate at least between a retracted configuration, in which the screening means permits light passage through the gap, and a deployed configuration, in which the screening means at least partially blocks the light passage in the gap;
• actuator means arranged in the box and comprising an electric motor operably associated with the screening means to alternate the screening means between the retracted configuration and the deployed configuration;
• power supply means operably connected with the actuator means and comprising:
• a stationary portion which comprises a support external to the gap and an electrical cable, the electrical cable electrically connecting the support to the electric motor;
• and
• a moving portion adapted to be electrically connected/disconnected to/from the stationary portion;
• and
• a control unit in signal communication with the electric motor, wherein the control unit is configured to switch on/off the electric motor;
• wherein the insulated glazing unit further comprises an active electronic circuit in signal communication with the control unit and configured to at least store identification data of the control unit, and
• wherein the active electronic circuit is integrated in the support of the stationary portion of the power supply means.
