A device for inductive positioning comprises a coil, an element for influencing a magnetic field in the area of the coil, a signal generator for providing a digital signal and a delay element with an input and an output, wherein the delay element is designed on the basis of the coil and a delay period between a signal edge at the input and a corresponding signal edge at the output is dependent on the inductance of the coil. The device further comprises a comparator to provide a digital differential impulse, whose length is dependent on a time difference of corresponding signal edges at the input and the output of the delay element, an integrator to provide a voltage depending on the length of the differential impulse and an evaluator to determine the position of the coil in reference to the coil based the voltage.

The approach relates to a procedure for determining a signal transmission quality of a light transmission path, which consists of a light transmitter on one end and a light receiver on its other end. A transmitter code is received in a first step. The transmitter code hereby represents a signal which is transmitted from the light transmitter to the light receiver. In a further step the receiver code is read in. The receiver code hereby represents a signal which was provided by the light receiver by using the transmitter code. The determining of a degree of correspondency between the transmitter code and the receiver code is performed in a final step of determining, in order to define the signal transmission quality of the light transmission path.

A driver assembly comprises several semiconductor switches that are arranged in a plane so that distances between adjacent semiconductor switches in the plane are equally large, and so that each semiconductor switch has the same number of adjacent semiconductor switches.

An apparatus is provided for the actuation of at least one pivotable external element of a vehicle, in particular of a top element of a convertible vehicle, with at least one pivot joint and a drive. The drive may be an electric motor which introduces a drive torque directly into the at least one pivot joint.

Device for actuating at least one pivoted exterior element of a vehicle

A folding convertible top for a convertible vehicle includes a rotational angle detection device disposed in a rotary hinge () for detection of the rotational angle between linkage arms () of a convertible top frame that are pivotably connected with each other by a bearing pin (). A rotational angle encoder () is connected with one linkage arm so as to rotate therewith and a sensor element () is connected with the other linkage arm so as to rotate therewith. The rotational angle encoder and/or the sensor element is/are disposed adjacent to the bearing pin on respective surfaces of the linkage arms facing towards each other or within housing parts () connected to the respective linkage arms.

Convertible top with a rotational angle detection device

A motor vehicle that is equipped with a movable convertible top comprising control equipment for controlling the convertible top motion and a detection device for recognition of an intervention into the range of motion of a convertible top mechanism, which is equipped with a sensor system with sensors operating with different measurement principles, wherein, when recognizing a malfunction of the detection device or when recognizing an obstruction situation, the convertible top motion is controlled in a safety mode during which the convertible top motion continues with reduced speed and power or is stopped or reversed.
