Abstract: Device for laser surveying of an environment A device for surveying an environment by time-of-flight measurement of laser beams reflected therefrom comprises a beam deflection device having at least one mirror surface which can be rotated or oscillated about an axis of rotation which is non-normal to the mirror surface. The device further comprises a first laser transmitter with associated first laser receiver, and a second laser transmitter with associated second laser receiver. The transmission and reception directions of the first and second laser transmitters and receivers lie parallel to one another in pairs and at different angles to the axis of rotation. The first laser receiver is spaced apart from the first laser transmitter and the second laser receiver is spaced apart from the second laser transmitter, in each case in the direction of the axis of rotation.

Abstract: An apparatus for surveying an environment comprises a first and at least one further scanning unit each for transmitting a pulse train of laser pulses over successive deflection periods at a pulse repetition rate, wherein the laser pulses falling in each deflection period form, per deflection period, a scanning fan which the laser pulses scan with a predeterminable angular velocity profile, and for receiving the associated laser pulses reflected by the environment. All the scanning fans overlap as seen in the direction of one of the scanning axes. The apparatus further comprises a control device connected to the at least one further scanning unit and configured to pivot the scanning fans of each further scanning unit relative to the scanning fans of an adjacent scanning unit by a pivot angle dependent on the pulse repetition rate and the angular velocity profile, in such a way that their sampling points do not coincide.

Abstract: An apparatus for surveying an environment comprises a first and at least one further scanning unit each for transmitting a laser beam over a series of deflection periods with a respective deflection period duration, which laser beam in each deflection period scans over a scanning fan and scans the environment along a scan line, wherein the scan lines of each scanning unit form a scan line group, and for receiving the associated laser beam reflected from the environment. The apparatus further comprises a control device connected to the at least one further scanning unit and configured to offset the scan line group of each further scanning unit with respect to the scan line group of an adjacent scanning unit in the direction of movement by a position offset which is dependent on the relative speed and the deflection period duration, in such a way that their sampling points coincide.

Abstract: A casing for a drive unit, particularly a drive unit for a wiper apparatus, consists of plastic reinforced with glass fiber. The drive unit casing is open at one side and is sealed there by means of a metallic cover, where the cover serves at the same time as an axial support for the support axes of the drive unit. The use of plastic reinforced with glass fiber gives the casing a sufficient strength, and additionally has the advantage that the drive unit casing is significantly lighter than corresponding casings which are constructed in metal.
