Abstract: An insulated glazing unit may include: a frame; at least two panes associated with the frame to define a gap; a box inside the gap; screening means in the gap configured to alternate between at least retracted and deployed configurations; an actuator in the box, wherein the actuator may include an electric motor to move the screening means between the retracted and deployed configurations; a power supply including: a stationary portion, including a support external to the gap and an electrical cable to connect the support to the electric motor; and a moving portion, configured to electrically connect to/disconnect from the stationary portion; a control unit in signal communication with the electric motor, configured to switch on/off the electric motor; and an active electronic circuit in signal communication with the control unit and configured to store identification data. The active electronic circuit may be integrated in the support.

Abstract: The present invention concerns a system for screening a fixture, such as a Venetian blind in a double glazing, comprising at least one screening element, and a transmission system connected to it for moving it between different operating positions and causing different levels of screening of the fixture. The transmission system comprises two pulleys and a transmission belt with a toothing for meshing with at least a first pulley. A barrier element, for example a U-shaped or closed profile, is arranged between the pulleys and is interposed between two longitudinal sections of the belt to prevent contact between distinct portions of the toothing of the belt.

Abstract: The present invention relates to an insulated glazing unit (1) adapted to be inserted in a door or window comprising a frame (2); at least two partially or totally transparent panes (4) associated with said frame (2) to define a gap (5); screening means (6) inserted in said gap (5) and adapted to be alternated at least between a retracted configuration in which they allow the passage of light through said gap (5) and a deployed configuration in which they at least partially block the passage of light in said gap (5); actuator means (8) comprising an electric motor (8a) operably associated with said screening means (6) to alternate them at least between the retracted configuration and the deployed configuration; power supply means (13) operably connected to said actuator means (8) and comprising a stationary portion (14) and a moving portion (15) adapted to be electrically connected/disconnected to/from said stationary portion (14), a control unit (9) in signal communication with said electric motor (8a) of sa
