Title: Tapani Vistbacka: Innovator in Positioning and Filter Technology
Introduction
Tapani Vistbacka is a notable inventor based in Kempele, Finland. He has made significant contributions to the fields of positioning technology and filter design, holding a total of three patents. His innovative work has implications for mobile communication and signal processing.
Latest Patents
One of Vistbacka's latest patents is a method and arrangement for performing positioning. This invention relates to determining the location of one or more mobile stations using at least two radio direction-finding stations. The system maintains information on the location of each mobile station on a server. The mobile station measures variables proportional to its vertical location and signals this information to a control unit. The control unit then determines the vertical location based on the data received, allowing for the graphical display of the three-dimensional locations of the mobile stations.
Another significant patent is for a resonator filter with reduced variation in pass band attenuation. This invention involves a bandpass filter made up of coaxial resonators. An additional equalizing resonator is coupled to a resonator in the chain, which helps to decrease attenuation variation across the pass band. This innovative structure allows for a reduction in pass band attenuation variation with fewer resonators than traditional designs, while also keeping production costs low.
