Abstract: An adjustable shutter assembly having an automated adjustment system including an electronic actuating device, such as an electric actuating motor. The shutter assembly has at least one and typically a plurality of parallel slats rotatably attached at both ends to a frame. The actuating motor is embedded within a self-contained module that can strengthen the shutter frame and be hidden from view. The actuating motor has a spindle that is coaxially connected to one end of an actuator slat selected from among the plurality of parallel slats. The spindle typically includes a tongue that engages a receiving pocket of the actuator slat without additional fastening mechanisms. One or more of the other slats are interconnected with the actuator slat such that rotation of the actuator slat is accompanied by substantially synchronous rotation of the other slats interconnected thereto. Selecting the actuator slat from among the more centrally located slats provides for more reliable and secure closure of all slats.
