Abstract: This disclosure presents a safe high speed roll-up door with spiral brackets. To enable a high speed operation, robust spiral brackets having efficient spacing are provided to guide the plurality of sectional slats. Durable and low noise signature rollers are used. A unique assembly configuration of the slats and the tracks guiding the rollers enable quick replacement of each individual roller without disassembling the door. A double-belt counter weight mechanism balances the door and incorporates safety sensors that prevent loosening the belts when the door is jammed. The belts are further adjustable using ratchets such that adjustment for the horizontal balance as well as weight position is made effortless. In all, the high speed roll-up door using sectional slats performs faster and quieter, withstands greater loads, and lasts longer than other existing roll-up doors with spiral brackets.

Abstract: An Internet based system for remotely monitoring and changing the open/closed door status of a garage door. A position detector is coupled to the door. Two position detectors, preferably substantially orthogonal with respect to one another, determine the barrier status. A wireless transmitter transmits the barrier status to a multi-functional control module. The control module also receives a change of status command from the Internet Cloud to move one or more doors in accordance with the command. Multiple relays paired with the doors allow the control module to control a plurality of doors.

Abstract: This disclosure presents methods and/or processes for forming a garage door façade using variable pressure. The forming processes, different from common stamping processes, creates a shaded design in a garage door section such that a continuous pattern is realized in the length direction (i.e., the longest side of the garage door section). The forming processes also produces significantly deep and smooth impressions that deform the center of the design. The forming process may be preceded by a texturing process, for example, each garage door section may first be textured and then sent for forming the design.
