    摘要: An electrical receptacle defines a receptacle formation of a mating formation pair to prevent a standard plug from establishing electrical connection while permitting an otherwise standard plug defining a corresponding plug formation to be sufficiently inserted to establish an electrical connection. The mating formation pair may include a projection on the receptacle adapted for receipt by a corresponding recess on a compatible plug. Alternatively, the mating formation pair is defined by an opening of the receptacle and a conductor of the plug, each having a cross-sectional height that is reduced from that of a standard receptacle and plug. The mating formation pair is particularly desirable for installation including a receptacle controlled by a dimmer to prevent electrical connection by a standard plug connected to a non-dimmable electrical load.

    摘要: Calibration of a motorized roller shade is accomplished by calculating a radius of a roller tube and thickness of a shade fabric rotatably supported by the roller tube. First, a lower edge of the shade fabric is moved to a first position at a first linear distance from a predetermined position. Second, a first number of revolutions of the roller tube between the first position and the predetermined position is determined. Next, the lower edge of the shade fabric is moved to a second position at a second linear distance from the predetermined position and a second number of revolutions between the second position and the predetermined position is determined. Finally, the tube radius and the fabric thickness are calculated from the first and second linear distances and the first and second numbers of revolutions. The tube radius and the fabric thickness are used to control the linear speed of the lower edge of the shade fabric.
