Title: ANGLE OF ROTATION SENSOR, A LINEAR DISPLACEMENT SENSOR, A DOOR MOUNT MECHANISM, AND AN ELECTRICAL BRUSH
Abstract:
An angle of rotation sensor for measuring an angle of rotation of a rotatable object includes an electrically conductive band to be disposed onto the rotatable object and having two terminal ends which are spaced apart from each other and which are respectively applied with different voltages; an electrical brush in electrical contact with the electrically conductive band; and a voltage measuring device coupled to the electrical brush and measuring a divided voltage which is a voltage at a position of the electrically conductive band at which the electrical brush contacts. The angle of rotation of the rotatable object is associated with the divided voltage and the different voltages.
