Patent DE-19734722-A1 (DE)
Inventor: WEINHOLD MICHAEL
IPC: H02J1/00
Filed: 1997-08-11
Abstract: The invention relates to a method and device for improving the current quality of a superimposed network (14) by means of a compensation device (2) which is connected parallel to the network (14) and to a load (12) and provided with a pulse current converter (4). The control and regulating system (10) of the converter determines a transmittance space vector (ü) on the basis of a supply voltage and line current space vector (uN,iN) together with the actual value of a direct current voltage(Vdc). According to the invention, a compensated voltage fundamental space vector (uk,1) comprising a space vector for a compensated voltage fundamental positive phase sequence system and a space vector for a compensated voltage fundamental negative phase sequence system is generated. This enables the compensation device (2) to balance a high dynamic load and to compensate reactive power in relation to the fundamental frequency currents of a particular load (12), so that said load (12) when seen from the point of view of the superimposed network in relation to the fundamental mode can appear as a three-phase, symmetrical, ohmic resistance.

Title: Control circuit for motor vehicle automatic transmission
Inventor: IBAMOTO MASAHIKO
IPC: F16H9/00
Filed: 1997-11-25
Abstract: The control circuit monitors the setting of the throttle pedal and the rate at which the pedal is operated to determine which mode of driving is required; fuel saving of acceleration.

The two modes of driving, fuel economy and acceleration, are combined to provide a variation of driving mode which can be matched to the operation of the driver's controls. The control circuit derives the target settings for engine torque etc. with a minimum of delay, independent of the type of vehicle used.
Patent DE-19754031-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 M1 receiver sensors (S1 à SM) of a linear antenna group (ULA) are picked up. Each receiver signal comprises partial waves of a sender signal having different direction of incidence and different delay. The sender signal contains a preselected test sequence and the angle of incidence and the delay of the dominant wave fronts are calculated simultaneously taking into account the chip signal form of the test sequence. The signals of each antenna sensor are demodulated. Detection with Mc detection values of each chip of the test sequence is then conducted. The resulting detection values Nc x Mc 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 can be assembled in a data matrix XF'(n) which contain the invariances characterizing the channel.

Title: Speech communication method for underground working
Inventor: PRUMBACH WILHELM-HERMANN
IPC: H04L12/407
Filed: 1998-01-22
Abstract: The method involves converting an analogue speech signal into a digital signal at the transmission side, where it is transmitted digitally via a bus system (1).

Patent DE-19822453-A1 (DE)
Title: Method of absolute testing of aspherical surfaces using computer generated diffractive elements
Inventor: SCHWIDER JOHANNES
IPC: G01J9/00
Filed: 1998-06-20
Abstract: The method involves using interferometry of Shack Hartmann sensing to measure wave front deformations. The method involves constructing a spherical auxiliary wave in a diffractive optical element. This is encoded with the same average wave front curvature and the same direction of curvature as an aspherical wave. The auxiliary wave can be easily separated from the actual aspherical wave front by a small lateral focus shift with appropriate filtering. The aspherical wave meets the test surface at a right angle and is reflected and then deformed by a diffractive element selectively into a planar or spherical wave. This is then caused to interfere with the reference wave, The auxiliary wave is used to calibrate the interference arrangement in which several interferometry settings are realized successively, including a cat's eye position and different rotational positions of the aspherical test surface or an absolute tested spherical auxiliary surface.
