Novoflect develops intelligent and reflective surfaces (RIS = Reconfigurable Intelligent Surfaces) for the future 6th generation of mobile communications (6G). These surfaces are to be designed in such a way that they can guide and control radio waves in a targeted manner, e.g. to efficiently close dead spots. To this end, suitable materials, design approaches and circuits will be investigated in order to develop a single reflective element for use in the GHz frequency range. The individual elements are then combined to form an array. By developing a phase shifter circuit and a control unit for the array, a demonstrator of the overall system will be created.

The MPC platform developed by utilacy offers companies a simple, cost-effective and flexible solution for collaborative confidential computing. It allows data to be analyzed within the company, across company boundaries and even with competitors without exposing sensitive information. The utilacy platform enables companies to fully exploit the untapped potential of their confidential data. The platform encrypts the data to be analyzed directly on the data source (e.g. server or mobile device) and then distributes the data to multiple parties. What is special about this is that the source data never leaves the data source and therefore no party, including us as the operator of the utilacy platform, has access to this data.
