The present invention is a gear driven louver shutter system, wherein each louver of the shutter system is attached to the end of a pinion at both its ends. The base of each pinion is engaged with a gear strip disposed within each frame member, with a glide strip having a channel for the gear strip to glide within. When one louver is adjusted, all the louvers in the shutter system will move accordingly, due to the movement of the gear strip rotating the pinions in that frame member at the same rate. The glide strip may be held within the frame member by a friction fit or a clamping groove on the inside wall of the frame member.

A garage door apparatus is described as having a one or more rotating panel. This rotating panel can also retract into the surrounding garage door structure to create an opening in the garage door. The panels may be rotated and/or retracted automatically by a user or as directed by monitoring software. A user may operate the apparatus through a specially programmed wireless communication device enabled with a user interface and coupled via a communications network. Alternatively, the user may choose to program the apparatus to react automatically based upon environmental inputs such as the detection of unsafe levels of Carbon Monoxide, excessive temperatures, or rain.

A shutter panel includes a frame, and a louver coupled to the frame for rotation about a longitudinal axis across a given angular travel range of the louver. The shutter panel also includes a louver closure assembly operable to automatically rotate the louver into a closed position when the louver is moved into a specific angular range of louver positions within its angular travel range. For instance, in an exemplary implementation, the louver closure assembly is configured to linear translation into rotational movement of the louver.
