Abstract: In a method for adjusting a vehicle-mounted radar sensor having three radar lobes, which are emitted in a fan-shaped manner, one of which is a central lobe, and the other two are lateral lobes extending at the same angle, a reflector plate disposed at a distance from the vehicle and perpendicular to the vehicle longitudinal axis is pivoted about a vertical axis. The deviation of the reflector's position angle from an ideal position is determined. The ideal position is one in which the two lateral radar lobes produce at least a substantially identical reflection signal. The radar sensor is subsequently pivoted by a correction angle, which is equal to the deviation of the reflector plate's position angle, but in the opposite direction.

Abstract: A device and process for measuring distances and/or speeds between a motor vehicle and several objects, like mobile targets and fixed targets, has an FMCW radar system, where the motor vehicle transmits a signal, whose transmitting frequency is modulated with at least two frequency ramps. A device detects the receiving signals from the objects and determines the respective straight lines and the intersecting points of these straight lines in a speed-distance diagram. A sorting device sorts out the intersecting points from fixed targets and the related straight lines. A device outputs the distances and/or the speeds, which correspond to the other intersecting points.

Abstract: A steer-by-wire steering system comprised of an electronically regulated steering positioner mounted to the steering gear of the front axle or to both front wheels of a vehicle together with an electronic steering regulator and a feedback actuator. A sensor senses the driver's selected direction from the steering wheel. Road feedback can be relayed to the driver through a feedback actuator via the steering wheel. The loss of road feel caused by the absence of the steering column, which normally strongly influences the driver's directional wish, is recreated by the feedback actuator.

Abstract: A method of radar imaging moving objects, especially ground traffic at airports, uses inverse synthetic aperture radar (ISAR). The two-dimensional location distribution of backscatter centers of the object is detected. A plurality of range bins are provided for suppressing of interference, created because of Doppler shifts, in microwave images represented in the form of pixels. Only those pixels are considered to be active which exceed a defined intensity threshold value, which had previously been determined as a fixed fraction of the maximally present pixel intensity. A range area with interference is determined with the aid of a method wherein the threshold is exceeded and wherein the number of active pixels in the individual successive range bins is counted, and wherein image opening is performed in the detected interfered range area, which consists of a succession of a single or several repeated "erosions" and "dilatations".

Abstract: The disclosure is a process for recovering caprolactam monomer and oligomer from aqueous polycaprolactam extracts by removing the inorganic contaminants present therein.
