Abstract
A device and a method determines the position of an object which can be moved in a linear manner. The device includes a contact unit coupled to the object such that the contact unit provides a force signal that is dependent on the position of the object; a force detecting unit for detecting the force signal provided by the contact unit; and an evaluating unit for evaluating the force signal detected by the force detecting unit. The position of the object is ascertained using an evaluation function during the evaluation process, the evaluation function describing a dependence of the force signal on the position of the object.

An apparatus for determining a position of an object which can be moved in a linear manner, comprising:
- a contact unit, coupled to the object, generating a force signal dependent on the position of the object;
- a force detection unit detecting the force signal supplied by the contact unit;
- and
- an evaluation unit evaluating the force signal detected by the force detection unit.
A method for determining a position of a linearly movable object, comprising
- generating a force signal dependent on the position of the object by a contact unit coupled to the object;
- detecting the force signal by a force detection unit;
- and
- evaluating the force signal by an evaluation unit based on an evaluation function which describes a dependence of the force signal on a coordinate specifying the position of the object.
