Title: Meinhard D Ullrich: Innovator in Acoustic Modeling and Mobile Radio Systems
Introduction
Meinhard D Ullrich is a notable inventor based in Cologne, Germany. He has made significant contributions to the fields of acoustic modeling and mobile radio systems. With a total of 3 patents to his name, Ullrich's work has had a profound impact on technology and communication.
Latest Patents
Ullrich's latest patents include a method for determining an acoustic model for a word. This method is essential for the recognition of spoken text, as it requires words to be available in an acoustically modeled form. The process involves deriving characteristic values from a known spoken text during a training phase. These values are arranged according to triphones to form groups or clusters, which serve as the basis for reference values. This innovative approach allows for the modeling of a vast majority of words, even those containing triphones that have not occurred during the training phase.
Another significant patent is related to a spread-spectrum based cellular mobile radio system. This system addresses average mutual interferences between radio zones by utilizing statistical methods. Interference measurements are conducted in various radio zones, and the data is transmitted to a central control arrangement. This arrangement resolves the average mutual interferences and uses them in an optimization process to acquire access control parameters. This innovation helps avoid system overload and provides a flexible tool for meeting operator demands.
