System Architecture of a Mixed Reality Framework

In this paper the software architecture of a framework which simplifies the development of applications in the area of Virtual and Augmented Reality is presented. It is based on VRML/X3D to enable rendering of audio-visual information. We extended our VRML rendering system by a device management system that is based on the concept of a data-flow graph. The aim of the system is to create Mixed Reality (MR) applications simply by plugging together small prefabricated software components, instead of compiling monolithic C++ applications. The flexibility and the advantages of the presented framework are explained on the basis of an exemplary implementation of a classic Augmented Realityapplication and its extension to a collaborative remote expert scenario.

The New Swiss Patent Ligitation System

Switzerland is about to implement a completely new patent litigation system, following the establishment of a new specialized federal patent trial court and the replacement of twenty-six cantonal codes of civil procedure with a single uniform federal code of civil procedure. This article provides an overview of the general structure and the most important features of the new patent litigation system that may be of interest to international patent litigants and litigators.
