A drive system for raising and lowering a window covering using a continuous cord loop that includes a motor with an associated encoder, device controller for the motor, a speed sensor, and proportional-integral-derivative (PID) layer. The device controller stores or receives a desired motor speed and generates a speed command signal to the motor.

The PID layer uses the error to calculate a new output via PID control terms to automatically correct signals to the motor to achieve desired motor speed. A hembar alignment function automates positional control of a plurality of motor drive systems to synchronize raising or lowering of window covering shades with the shades in positional alignment. A system controller includes a time-counter indexed to a position scale to synchronize hembar alignment positional commands.

A motor driven system for raising and lowering a window covering executes motor ramp trajectory speed control. The motor ramp trajectory limits acceleration of an external motor from the idle (stationary) state to full operating speed, and limits deceleration of the motor from full operating speed back to the idle state. This function reduces stresses on a continuous cord loop drive mechanism. A control system manages solar heating effects in response to sunlight entrance conditions such as system sensor outputs, external weather forecasts, and other data sources. The system automatically opens or close the window covering to increase or decrease admitted sunlight under appropriate conditions. The input interface of the control system includes a visual display and input axis, which are aligned vertically if the window covering mechanism raises and lowers the window covering, and are aligned horizontally if the window covering mechanism laterally opens and closes the window covering.

Adjustable mounting system for window blinds and shades
A mounting system for a roller blind includes a tension bar for mounting under pressure between first and second sides of a windows frame. The tension bar may provide both long and short adjustment of mounting system width. The tension bar extends through a hollow roller tube of the roller blind, and through a clutch mechanism of the roller blind, and is coupled to end mounting fixtures. The length of the tension bar may be adjusted as a long adjustment of mounting width. Various mechanisms may be associated with one or both of the end mounting fixtures for short adjustment of mounting width, such as a latch mechanism, wedge mechanism, spring-loaded mechanism, or turn-buckle system. End pads at the ends of the blind provide friction and absorb excess pressure. The mounting mechanism serves as a universal window blind bracket and support rod, which requires no screws or nails to install.
