Patent DE-19860278-A1 (DE)
Inventor: ENDERLEIN JOERG
IPC: G01N15/14
Filed: 1998-12-24
Abstract: The aim of the invention is to facilitate a quantitative analysis of the optical brightness of particles immobilized on a surface. According to the inventive method, the surface (8) is irradiated with a light beam (5) in such a manner that an elliptic focus (7) with a longitudinal axis and a shorter transversal axis is produced on the surface. The surface (8) with the immobilized particles is displaced in the direction (9) of the transversal axis of the elliptic focus, causing the particles to migrate across the focus. The optical signal of the particles produced in the focus (7) is imaged via a collection optics onto a slit diaphragm. Through said slit diaphragm only particles from a center section of the elliptic focus are detected. These particles are subjected to substantially the same excitation intensity. Therefore, their signals have a better definition in terms of quantity, thereby allowing a quantitative evaluation of the signal intensities.

Patent DE-19905884-A1 (DE)
Inventor: HAGER ROLF
IPC: H04Q7/38
Filed: 1999-02-11
Abstract: According to the invention, data sets of a network operator relating to the user behavior in the mobile radio network of honest customers and those with fraudulent intentions are examined on the basis of stochastic models. Beyond the one-dimensional filters that are implemented in MEGS, the invention provides a method for a computer-aided detection of frauds. A principal component analysis provides a graphic tool for easily identifying the data of defrauders by two-dimensional plots and corresponding staining, namely by visual inspection or an automated, computer-based test. According to the invention, an automated test on the basis of Fisher's discriminatory analysis is carried out which identifies simultaneously from among the highly dimensional data sets those data sets that belong to defrauders. Both methods are characterized in that they have small error probabilities of the 1<st> and 2<nd> order while requiring few calculation operations. The invention provides a high detection probability at a low false alarm rate.

Patent DE-19908635-A1 (DE)
Inventor: EISENHARDT HARALD
IPC: G01R19/165
Filed: 1999-02-27
Abstract: The invention relates to an arrangement for detecting the current by means of a precision resistor of a load current circuit. Said arrangement comprises an operational amplifier. The voltage drop at the precision resistor can be fed to said operational amplifier which emits an output signal at the output, whereby said signal is proportional to the detected current. Current measuring is made independent from the offset voltage of the operational amplifier by including the precision resistor in an additional voltage divider. A driving voltage for the operational amplifier can be picked up when the load current circuit is switched off. Said driving voltage is greater than the maximum offset voltage of the operational amplifier. The occurring output voltage of the operational amplifier is fed to a microcomputer which allocates said output voltage to the current value  zero  by the precision resistor. The driving voltage at the operational amplifier increases due to the voltage drop at the precision resistor when the load current circuit is closes. The microcomputer emits an output signal that is proportional to the voltage increase.
