A door operator system (1) for opening and closing an opening (2), comprising a door frame (3) comprising a first frame section (4) at a first side (5) of the opening (2) and a second frame section (6) at a second side (7) of the opening (2) and a door (8) arranged to be moved between an open (O) and closed (C) position. The door (8) is connected to the door frame (3). A drive unit (10) mounted on the door (8), whereby the drive unit (10) is moveably connected to first frame section (4) and the drive unit (10) is moveably connected to the second frame section (6), the drive unit (10) comprising at least one motor (11) connected to at least one energy storage device (12) arranged to power the at least one motor (11), the drive unit (10) being arranged to move the door (8) from the closed position (C) to the open position (O). The door operator system (1) further comprises an energy transmitting device (13, 14) disposed in close proximity to the door (8) and an energy receiving device (81) mounted on the door (8), whereby the energy transmitting device (13, 14) is configured to wirelessly transmit energy to the energy receiving device (81) mounted to the door (8), whereby the energy receiving device (81) is operatively connected to the at least one energy storage device (12) for charging said energy storage device (12).

An intelligent window allowing ventilation has an outer frame, a sliding frame, an upper locking rod, a lower locking rod, a driving module, a power supply module, and a switch assembly. The sliding frame is slidably mounted in the outer frame. The switch assembly controls the driving module to selectively drive the upper locking rod and the lower locking rod to two locking positions respectively, two ventilation positions respectively or two unlocking positions respectively. Since no handle is needed, an appearance of the intelligent window is neat and scenery outside the intelligent window would not be sheltered. In addition, by actuating the switch module to electrically drive the upper locking rod and the lower locking rod, a user is able to switch the intelligent window to a locked state, a ventilation state or a unlocked state. It is labor-saving and simple in operation.
