Abstract
The invention is an intelligent headrail for a window covering which includes an extensible end cap which applies force to the adjacent window or door frame to hold the headrail in place. The end cap includes a pressure sensor or a force sensing resistor to detect whether sufficient force is present to safely hold the headrail in place. The headrail may include a controller which is connected to the pressure sensor or a force sensing resistor. The controller may include program code which identifies the safety status of the window covering based on the pressure or force reading. The controller may include a data transmission port which transmits pressure or force readings to an output device. The program code may also send a report to the output device to indicate whether the force or pressure is moderately low or so low that the window covering is in danger of falling.
