OPoLiCom – Optimized Powerline Communication System

OPoLiCom is a system that continuously monitors the access impedance over frequency. If the access impedance spectral density below a threshold value, in the respective frequency range, no power is fed. Since the maximum power consumption of a PLC transmitter is limited, it ensures that in the frequency ranges with sufficiently high access impedance sufficient power can be fed. This is necessary for a good signal-to-noise ratio. By using OFDM with strong channel coding as in the just now standardized method, the absence of a portion of transmission frequencies can be compensated without any information to the receiver. This allows a standard-compliant implementation.

N-terminally modified tetrapeptide derivatives having a C-terminal arginine mimetic as antiviral protease inhibitors

The invention at hand provides novel inhibitors for human proprotein convertase, which have antibacterial and antiviral effects. These inhibitors are multibasic, N-terminally modified tetrapeptide derivatives having a C-terminal P1-arginine mimetic. In contrast to previous active substances against bacterial and viral diseases, the substances presented here do not apply to the pathogenic organism, but the host, so that there is no development of resistance to contend with.
