Abstract: A method for measuring an angular position of a rotatable signal-inducing unit uses a sensor unit electrically isolated from the signal-inducing unit. The signal-inducing unit has a center electrode disposed in a signal-inducing unit plane and a rotary electrode disposed in the signal-inducing unit plane, the rotary electrode being conductively connected to the center electrode and laterally offset therefrom. The sensor unit has a first sensor electrode disposed in a sensor plane and at least one second sensor electrode disposed in the sensor plane, the sensor electrodes being arranged in a circle around a ground electrode disposed in the sensor plane, the signal-inducing unit plane and the sensor plane being oriented substantially parallel to one another. The signal-inducing unit is supported so as to be rotatable about the center electrode and the rotary electrode is movable along a circular path in the region of the sensor electrodes.

Abstract: A device for sensing a rotational position of a rotatable element for a household appliance includes: a stator having a plurality of capacitive sensor surfaces spaced apart from one another in a plane of extension of the stator; and a rotor rotatably positionable or disposed relative to the stator and having an electrically conductive section and a dielectric non-conductive section, the conductive section being larger in area than the non-conductive section, the rotor being disposed opposite the plane of extension of the stator in a rotatable condition relative to the stator, and the rotor being couplable or coupled to the rotatable element.

Abstract: A self-locking adjustable light fixture comprising an arm, a base, a hood, an arm securing mechanism, and a hood securing mechanism. The arm has an annular shape with interconnecting protrusions at a proximal end and a distal end. The base has mating interconnecting notches that are axially aligned with the interconnecting protrusions of the proximal end of the arm. The base is connected to the proximal end of the arm by the arm securing mechanism which biases the interconnecting protrusions at the proximal end of the arm with the mating interconnecting notches of the base to prevent rotation of the arm. The hood has mating interconnecting notches aligned with the interconnecting protrusions at the distal end of the arm. The hood is connected to the distal end of the arm by the hood securing mechanism which biases the interconnecting protrusions at the distal end of the arm into the mating interconnecting notches of the hood to prevent rotation of the hood with respect to the arm.
