System for Syncronizing a Plurality of Roller Shades Using Variable Linear Velocities

摘要

Presented is a system for synchronizing movement of roller shades each from a first position to a common second position. The system includes a master controller, a plurality of optical assemblies each configured to obtain information related to the position of one of the roller shades, and a plurality of motor assemblies. Each of the motor assemblies is configured for receiving the position information from one of the plurality of optical assemblies, receiving a master shade movement time from the master controller, and moving one of the of roller shades from the first position to the common second position in response to the received position information so that the roller shade arrives at the common second position simultaneously with the other roller shades in a time equal to the master shade movement time.
