    • An automatic torque-based control system is disclosed which can react to end points and obstructions through a torque sensing arrangement. This torque sensing can be accomplished through use of an electromagnetic interference device so that a change in torque is immediately detected and a modulation in operation of the shade can be effected. Rotating pitched disks elastically connected to each other can be used to act as the torque sensor for drive systems, and in particular and preferred embodiments, for window shade systems. Multiple elastic elements can permit multiple location sensing as well as non-zero, no-load, and fully loaded torque sensing and reaction.

    • A system for effecting and controlling the movement of a window covering between different positions. In particular, the present invention includes a motor coupled to a window covering by way of a drive assembly. The drive assembly includes one or more hollow shafts, a drive shaft, and a torque sensing mechanism. The drive shaft is coupled between the motor and a hollow, sliding shaft by way of the torque sensing mechanism. Rotation of the motor causes a lift cord to wind or unwind from the hollow sliding shaft wherein the frictional engagement of the lift cord against the hollow, sliding shaft causes the shaft to slide. Additionally, the present invention includes a method for detecting and responding to disturbances in force sensing devices coupled to the lift cord.
    • 用于实现和控制不同位置之间的窗户覆盖物的运动的系统。 特别地,本发明包括通过驱动组件耦合到窗户覆盖物的马达。 驱动组件包括一个或多个空心轴,驱动轴和转矩检测机构。 驱动轴通过转矩传感机构联接在电机和中空的滑动轴之间。 马达的旋转使提升绳索从空心滑动轴卷绕或退绕,其中提升绳索与空心滑动轴的摩擦接合使轴滑动。 另外,本发明包括一种用于检测和响应耦合到提升绳索的力传感装置中的扰动的方法。
