Compensation of spectral fractions in transmitting units

Method for reducing cross-talk / interference: The optimal utilization of the available frequency bands plays an important role in the transmission of messages. In frequency multiplexing, sub-frequency bands are allocated to individual communication channels, which are usually completely independent of each other. In practice, however, there is cross-talk, that is, in a channel, signals from the two adjacent channels are also received. Thus, the received signal is composed of useful signal and interference signal. The aim of the present invention is to compensate for the interfering signal component. This is particularly important when the intensity of the adjacent channel signals and thus the interference signal which they contribute are greater than the actual useful signal (“adjacent channel interference problem”).

Charge flow frequency converter

Charge flow frequency converters are used when especially small electrical currents must be measured. Usually, the integrator and the comparator are connected in series. The improved method can be used anywhere where very small currents of both polarities with high dynamics are measured.

A system for harvesting electrical energy during ski touring

Energy storage systems of electronic components have short lifetimes especially in winter which can be safety-relevant for longer outdoor activities . The present invention includes a means for energy production during nordic skiing activities. The mechanical energy of the pivoting foot movement is transformed into electric energy that can be used for the continual recharging of the energy reservoir.

Dosing system of bulk material (granulates) for expansion injection molding

Changing from injection molding to expansion injection molding requires a costly change of equipment. Scientists at Ostfalia University of Applies Sciences and Volkswagen AG developed a simple and cost-effective way to convert injection molding into expansion molding by simply exchanging the dosing system of current machines.

Highly conductive pastes for printable electronic applications and devices

At the Karlsruhe Institute of Technology (KIT), a new platform concept for the formulation of highly conductive, printable pastes has been developed. Corresponding pastes are free of polymeric or other non-volatile stabilizers and rheology control agents. Nevertheless, rheological properties like low-shear viscosity and yield stress can be adjusted in a wide range. Thus sedimentation /aggregation is prohibited and long-term stability can be guaranteed even for suspensions of high density particles (e.g. Ag, Ni). Also full control of the application behavior in many different printing/coating operations is furnished.

Efficient method for ‘Chain Multiplication’ of unsaturated fatty acids – synthesis of ultra long-chain compounds

Currently, there are only very few, costly synthetic routes for the production of ultra long-chain compounds, as they typically rely on tedious multistep reaction sequences.
At the University of Konstanz (in the course of a project funded by the Baden-Württemberg Foundation), an iterative method (any multiplication factor) has been developed that produces terminally functionalized, purely aliphatic compounds through a ‘Chain Doubling’ approach starting from common monounsaturated fatty acids. All starting materials are readily available and the individual steps of the catalytic process do not involve further reagents. Moreover, there is only a small amount of byproducts which makes the method very efficient.
The method described here can be applied for the production of high-melting, purely aliphatic polymers and nanocrystals.
