ABSTRACT:
A system and a method detect a position of a movable element within an interior of a compartment. The interior of the compartment has a light source, a light sensor, a base, a support and/or a movable element. The base is located between and/or is connected to the light source, the light sensor and/or the interior surface of the compartment. The base prevents the light source from being directed towards the light sensor. The light sensor detects an intensity of an emitted light in the interior of the compartment. The intensity of the emitted light detected by the light sensor corresponds to a position of the movable element within the interior of the compartment. The light sensor detects, measures, calculates and/or determines the position of the movable element based on the intensity of the emitted light within the interior of the compartment.
