Improved systems and methods for operating moveable architectural elements (e.g., furniture) are described. The system can include improved features implemented throughout various elements, including hardware elements, controller elements, and/or software elements. As one example, the system can feature the ability to map a characteristic load profile across a particular length of actuation and, if during operation a measured load exceeds the profile, adjust (e.g., stop) the system's motion. The system can also advantageously map its current draw to increase energy efficiency. In addition, the system can include a positioning system that enables it to automatically determine its position upon start up and during operation. In some implementations, the system includes multiple moveable elements (e.g., furniture items). In some cases, power is distributed to the moveable element(s) using a moveable power distribution module. Many other improvements and features are contemplated and described.

The present disclosure relates to an adjustable roller shade. In certain embodiments, the adjustable roller shade includes: a roller shade fabric winding shaft, a roller shade fabric wound on the roller shade fabric winding shaft forming upper edge of adjustable roller shade, a weight bar attached to bottom of roller shade fabric forming lower edge of adjustable roller shade, a pair of movable pulleys, two pairs of upward lifting ropes and downward pulling ropes, four winders, four driving motors, and a controller. The controller controls rotations of four driving motors, independently and in concert. Each of the four winders is independently driven by four driving motors respectively. Rotations of four driving motors cause rotations of four winders. Ups and downs of the upper edge and the lower edge of the adjustable roller shade can be achieved by controlling the rotational directions of the four winders, separately and independently.

A shutter roller door with a shutter roller drivable by a drive mechanism; a flexible door windable on the roller and movable between retracted and extended positions by the drive mechanism, the door having integrally formed interconnected slats, each having upper and lower edges, and arranged perpendicular to a direction of door travel; a guide rail assembly positioned at each side; and end members attachable to an end of a corresponding slat. Each slat has an upper hook portion and an upper curved channel, the upper hook portion configured to engage with a lower curved channel of the lower edge of an upper adjacent slat, and the lower edge having a lower hook portion and a lower curved channel configured to engage with the upper curved channel of the upper edge of a lower adjacent slat.

A motorized shade for covering an architectural opening that can be actuated by touching its shade material. The motorized shade comprises a shade material extending between an upper end and a lower end and a motor drive unit operably connected to the upper end of the shade material and comprising a motor and a motor control module adapted to control the motor to raise or lower the shade material. The shade material comprises at least partially comprises electrically conductive material. The motor control module comprises a capacitive touch sensor that is electrically connected to the upper end of the shade material via at least one electrical contact. The motor control module is adapted to detect a touch of the shade material via the capacitive touch sensor and in response control the motor to raise or lower the shade material.

Present disclosure relates to several adjustable roller shades. Adjustable roller shade includes: roller shade fabric winding shaft, weight, movable pulley, loop traction rope, two winders and two tensioning wheels. A roller shade fabric is wound on roller shade fabric winding shaft forming upper edge of adjustable roller shade. Weight is attached to bottom of roller shade fabric forming lower edge of adjustable roller shade. Movable pulley is fixedly attached to one end of the roller shade fabric winding shaft. Loop traction rope is wound around the movable pulley, two winders and two tensioning wheels. One or more driving motors drive the pair of winders to rotate in different combination of directions to raise or lower both upper edge and lower edge of adjustable roller shade, resulting the adjustable roller shade to be opened or closed freely from both upper and lower edges of the adjustable roller shade.

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.
