    摘要: A method and a system for detecting the spatial movement state of moving objects, e.g., vehicles. Due to a, for example, non-cartesian arrangement of four rotational rate sensors and/or acceleration sensors, it is also possible to obtain a redundant signal in addition to the desired useful signal indicating the spatial movement state, e.g., the rotational movement and/or acceleration in space; if this redundant signal is large enough in comparison with the rotational rate actually applied, it may be used for detection of the size of the error and the defective sensor. The four sensors are mounted, for example, on a sensor platform forming a three-sided truncated pyramid so that all possible three-way combinations of sensors are mutually linearly independent. The accuracy about the vertical axis is defined by the angle of inclination of the side faces of the truncated pyramid.

    摘要: An optical sensor for detecting wetting of a surface (11), In particular of a vehicle window, has at least one transmitter (13) and at least one receiver (15) for electromagnetic waves, the surface being located in a sensor region (16) between the at least one transmitter (13) and the at least one receiver (15). The development of wetting on the sensor region (16) of the surface (11) causes a signal change. The optical sensor has a light-carrying element (18), in which the electromagnetic waves are guided bidirectionally into the sensor region (16) and out of the sensor region (16), and a retroreflector (10) is disposed in the sensor region (16) in such a way that it returns the electromagnetic waves, reflected before the surface (11), back to the surface (11) and from there to the light-carrying element (18).

    摘要: A method is proposed for producing three-dimensional structures, especially microlenses, in a substrate using an etching process, at least one original shape having a known original surface shape being present initially on the substrate in a plurality of places. The etching process has at least one first etching removal rate a1 and a second etching removal rate a2 which are material-dependent, and of which at least one is changeable as a function of time. The original shape is converted to a target shape by the etching process, the original surface shape of the original shape and the target surface shape of the target shape to be reached being known before the beginning of the etching process. In order to achieve the target surface shape, at least one of the etching rates a2 or a1 is set by a change of at least one etching parameter calculated before the beginning of the etching process as a function of the etching time.
