Method for synchronizing a plurality of roller shades using variable linear velocities
First Claim
1. A method for synchronizing movement of a plurality of roller shades each disposed at a first position to a common second position, each of the plurality of roller shades including a flexible shade material having a lower end and a rotatably supported roller tube windingly receiving the flexible shade material, the method comprising:
- obtaining information related to the position of each of the plurality of roller shades with a respective one of a plurality of optical assemblies by capturing an image frame of each of the plurality of roller shades at a plurality of linear positions along the flexible shade material of each of the plurality of roller shades with a respective one of a plurality of optical sensors; and
moving each of the plurality of roller shades from the first position to the common second position in response to the respective obtained position information so that each of the plurality of roller shades arrives at the common second position at the same time.
