Patent DE-19641085-A1 (DE)
Title: Atomic change investigation method for materials testing e.g. metallography
Inventor: STENGEL WOLFGANG DR
IPC: G01N27/72
Filed: 1996-10-06
Abstract: The method uses an oscillation system for stimulating mechanical oscillation of the investigated material, with recording of the resulting oscillation characteristics. The oscillation is provided by the force of oscillating fields, alone or in combination with DC field or mechanical or thermal stress. The fields may be magnetic, electric or electromagnetic, and they penetrate the investigated material to a depth which is dependent on the frequency, with recording by a thin probe of the frequency-dependent oscillation characteristics via successive measurements, detecting changes in the oscillation characteristics.

Patent DE-19754030-A1 (DE)
Inventor: HAARDT MARTIN DR ING
IPC: H04B17/309
Filed: 1997-12-05
Abstract: Disclosed is a method for measuring the characteristics of radio channels, wherein the signals from M3 receiver sensors (S1 à S4) of a two-dimensional antenna group are picked up. Each receiver signal comprises partial waves of a sender signal with different two-dimensional direction of incidence and different delay as regards azimuth and elevation. The sender signal contains a preselected test sequence and the angle of incidence and the delay of the dominant wave fronts are calculated taking into account the chip signal form of the test sequence. The signals of each antenna sensor are demodulated and detection with Mc detection values of each chip of the test sequence is then carried out. The resulting detection values are transformed by discrete Fourier transformation in the frequency range. The resulting values are corrected taking into account the spectrum of the chip signal form, wherein the linear vectors formed for each sensor on the basis of the values obtained are assembled in a data matrix XF' which contains the invariances in the spatial frequency range characterizing the channel.
