Cordless window covering
A cordless window covering includes a first rail, a second rail, a covering body, two pulling cords, and a cord-retracting device including a first casing and an adjusting member movably disposed on the first casing. When relative motion of the first rail and the second rail occurs, the covering body is extended or retracted, and the two pulling cords apply a first force and a second force in opposite directions to the adjusting member respectively. When the first force does not equal to the second force, the user can exert slight force on the second rail to move the adjusting member towards a side with greater force, making one of the pulling cords applying greater force to the adjusting member have its length between the first rail and the second rail elongate as the adjusting member moves, such that the non-horizontal state of the second rail can be easily corrected.

ActiveUS12480345B1Door/window protective devicesWing suspension devicesStructural engineeringMechanical engineering
A bracket assembly for overhead roll-up doors includes a bracket body, and a head stop extending from the bracket body. The head stop is configured to limit travel of a roll-up door. The head stop includes perforated sections that create a hinge line in the material, allowing bending or rotation relative to the bracket body. The perforated sections include small, precisely spaced holes enabling the head stop to bend or fold into position. The bracket body and head stop form a gap at their intersection, creating a natural hinge point for bending the head stop. The head stop includes punched holes for attaching to vertical guides and additional head stops. The bracket body includes a bracket opening to receive an axle, a bracket stop cap, a tensioning drive, and guide tabs. The bracket body integrating the head stop reduces installation complexity and improves reliability compared to traditional separate component configurations.

Systems and method for controlling window treatments
A controller receives from a sensor associated with a window treatment a first data obtained during a controlled closing of the window treatment. A setpoint temperature, a current temperature within a structure, and a weather data is subsequently used to determine that the window treatment needs to be closed in order to hasten a movement of the current temperature towards the setpoint temperature. After an instruction is provided to cause the window treatment to start to close, second data is obtained from the sensor while the window treatment is being closed. The first data is compared to the second data, when the comparison indicates that an obstruction exists in a path of travel of the window treatment, the closing of the window treatment is stopped.
