The drive unit is positioned within a sill of the window. The cable system is engagable with the drive unit for moving a pane of the window relative to a window frame between an opened position and a closed position. The controller is electrically coupled to the drive unit and a power outlet located in the building and connected to an external power grid. ## Claims ### Claim 1 A power actuator for a window in a building, the power actuator comprising: a drive unit positioned within a sill of the window and including a motor; a cable system engagable with the drive unit for moving a pane of the window relative to a window frame between an opened position and a closed position; a controller electrically coupled to the drive unit and a power outlet located in the building; and a pulley positioned opposite of the sill of the window and the closed position of the pane of the window, wherein the cable system includes first and second cables driven by the motor, and two drums turnable in opposite directions and disposed next to one another in the sill of the window, wherein the first drum has a gear portion driven by a spur gear of the drive unit and directly engaged with a gear portion of the second drum, wherein the first cable winds about the first drum in a manner proportional to the second cable unwinding from the second drum, and wherein the first cable extends from the first drum in a direction opposite of the second cable extending from the second drum. ### Claim 2 (depends on 1) The power actuator of claim 1, wherein the first and second cables extend in a length direction of at least a portion of a distance between the drive unit and the pane of the window. ### Claim 3 (depends on 2) The power actuator of claim 2, wherein the first and second cables are rotatably driven by the motor to move the pane of the window relative to the window frame between the opened and closed positions. ### Claim 4 (depends on 2) The power actuator of claim 2, wherein the pulley is attached to the window frame. ### Claim 5 (depends on 4) The power actuator of claim 4, wherein the pulley is configured to allow a portion of the first cable to rotate thereabout when the pane of the window is moved relative to the window frame between the opened and closed positions. ### Claim 6 (depends on 2) The power actuator of claim 2, wherein the motor is electrically coupled to the controller and drives the first and second cables in first and second directions, thereby moving the pane of the window relative to the window frame between respective open and closed positions. ### Claim 7 A power window assembly comprising: a window having a sash movable between an opened position and a closed position; a drive unit including a motor; a first pulley fixed to a frame of the window and positioned within a sill of the window; a second pulley positioned opposite the sill of the window and the closed position of the sash; and a cable system including a first cable engagable with the first and second pulleys, drivable by the motor, and extending in a length direction at least a portion of a distance between the sash and the sill of the window, wherein the cable system further includes a second cable and two drums turnable in opposite directions and disposed next to one another in the sill of the window, wherein the second drum has a gear portion directly driven by a gear portion of the first drum, wherein the first and second cables are moveable to drive the sash between the opened and closed positions, wherein the first cable winds about the first drum in a manner proportional to the second cable unwinding from the second drum, and wherein the first cable extends from the first drum in a direction opposite of the second cable extending from the second drum. ### Claim 8 (depends on 7) The power window assembly of claim 7 further comprising a controller electrically coupled to a power outlet when the window is located in a building. ### Claim 9 (depends on 8) The power window assembly of claim 8, wherein a wall switch located in the building is configured to electrically couple the controller and power outlet. ### Claim 10 (depends on 8) The power window assembly of claim 8, wherein the controller is configured to receive power from the power outlet, thereby rotating the first and second cables and moving the sash of the window between the open and closed positions. ### Claim 11 (depends on 8) The power window assembly of claim 8, wherein the drive unit is electrically coupled to the controller and the motor drives the first and second cables to move the sash of the window between the open and closed positions. ### Claim 12 (depends on 11) The power window assembly of claim 11, wherein the drive unit is disposed in an interior space of the window. ### Claim 13 (depends on 7) The power window assembly of claim 7, wherein a portion of the first cable is rotatable about the second pulley to move the sash of the window between the open and closed positions.
