Patent CH-689335-A5 (CH)
Title: Laser Doppler signal evaluation method
Inventor: DAMMANN EHRHARD
IPC: G01S17/95
Filed: 1998-07-24
Abstract: The method involves comparing a phase of a detector signal containing a Doppler frequency with a sequence of four uniquely associated condition intervals of a orthogonal frequency system. A change of the phase, which triggers a compensation of the Doppler frequency through production of a regulated mixer frequency, and the regulated mixer frequency, are likewise compared with an orthogonal frequency system. The method involves producing at least one orthogonal frequency system (6), under application of a laser Doppler wind-speed meter (LDA) with band pass filtration and frequency delay demodulation. The frequency system consists of a sequence of four reversible, uniquely associated condition intervals of two overlapped rectangular functions with a phase of  pi /2. A detector signal containing a Doppler frequency (fD) is compared after the band-pass filtering, with respect to its phase with the condition intervals of the orthogonal frequency system. A change of the phase, which triggers a compensation of the Doppler frequency change through production of a regulated mixer frequency (fM) which is coupled in the laser Doppler wind-speed meter (1), and the regulated mixer frequency as equivalent of the Doppler frequency, are likewise compared with an orthogonal frequency system, and are evaluated due to the reversible unique sequence of the condition intervals.

IPC: E01C23/16
Filed: 1979-12-21
Abstract: The marking vehicle which is designed to accommodate spraying receptacles (6) containing marking paint has a chassis which is solely composed of two longitudinal rods (1) and one crossmember (4) which is releasably fastened to the longitudinal rods (1) in such a way that its length can be changed. The crossmember (4) acts as the support for a desired number of spraying receptacle holders (5). The longitudinal rods (1) and the changeable crossmember (4) are preferably composed of square aluminium profiles. Each spraying receptacle holder (5) is fastened to a supporting column (10) so as to be vertically adjustable by means of a supporting arm (12), the bottom of the said column (10) resting on a U-shaped supporting part (9) which encloses the crossmember (4) from above and can be displaced along the said crossmember (4). All spraying receptacles (6) required for marking to take place can be jointly operated by means of Bowden cables (18, 20). The ends of the crossmember (4) can be designed for the mounting of crossmember pieces which laterally overlap the wheel track width and are used for the mounting of further spraying receptacle holders (5).   The marking vehicle makes it possible, by selection of an appropriate number of spraying receptacles (6) which are arranged alongside one another on a crossmember (4) of desired length, to apply or renew markings of any width up to 1 m, for example, double or multiple lines, or even multicoloured markings in a single operating cycle. <IMAGE>
