Abstract
A device and a method determine the position of an object which can be moved in a linear manner. The device includes a contact unit which is coupled to the object such that the contact unit provides an angle signal (α) that is dependent on the position of the object. An angle detecting unit detects the angle signal (α) provided by the contact unit, and an evaluating unit evaluates the angle signal (α) detected by the angle detecting unit. The position of the object is ascertained using an evaluation function (a(X)) during the evaluation process, the evaluation function describing a dependence of the angle signal (α) on the position of the object.

14. An apparatus for determining a position of an object which can be moved in a linear manner, the apparatus comprising:
-
a contact unit which is coupled to the object such that it produces an angle dependent on the position of the object; an angle detection unit to detect the angle produced by the contact unit, and to produce an angle signal based thereon; and an evaluation unit to evaluate the angle signal produced by the angle detection unit and to determine the position of the object from the angle signal. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for determining a position of a linearly movable object, comprising:
-
producing an angle dependent on the position of the object using a contact unit coupled to the object; detecting the angle dependent on the position of the object and producing an angle signal thereform; and evaluating the angle signal and determining the position of the object based on an evaluation function which describes a dependence of the angle signal on a coordinate specifying the position of the object. - View Dependent Claims (26, 27)
