Abstract
In one example, an apparatus includes a sensor including an emitter and a detector that define a line of sight therebetween. A mechanical arm has a fixed end and a free end. An axis of rotation passing through the fixed end of the mechanical arm is parallel to the line of sight. A mechanical flag mounted to the fixed end of the mechanical arm includes at least a first protrusion that defines at least three positions of the mechanical arm relative to the line of sight.
