Abstract: A first communication device configured to communicate with a second communication device via two links comprises circuitry configured to switch between a full operation mode and a partial operation mode and control the moment of switching between the full operation mode and the partial operation mode and/or the moment of accessing the second link in the full operation mode under consideration of a switching delay indicating a delay between the initiation of switching between the full operation mode and the partial operation mode and the completion of the switching. In the full operation mode a first link of the two links is disabled and a second link of the two links commonly uses RF chains of both links for the communication with the second communication device and in the partial operation mode each link uses its RF chain for the communication with the second communication device.

Abstract: A method for analyzing appliances in a power line network, comprises obtaining an electrical characteristic of the power line network, using a sensor that is connected to the power line network, and detecting an appliance connected to the power line network on the basis of the electrical characteristic of the power line network and a model profile. The model profile is based on electrical characteristics of one or more candidate appliances and on a configuration of the power line network.

Abstract: A method for operating a PLC system including at least one PLC modem device, in which interferences on transmission signals of the PLC system and/or on a transmission spectrum of the PLC system are detected, the interferences are caused by influences of an impedance modulating device connected to a mains used by the PLC system for communication, and, in a case such interferences are detected, frequencies on which the impedance modulating device causes interferences are selected to be notched from power line communication and/or time periods when the impedance modulating device is in a switching mode are selected to be avoided for transmitting PLC signals. A PLC modem device and a PLC system can implement the method.

Abstract: A method for discriminating textured regions and homogeneous or flat regions in an image. A multi-scale or multi-resolution measurement is performed with respect to the image. Alternatively or additionally, the image is analyzed by using a prior measured noise value and a local variance value in or with respect to the image.

Abstract: From first and second image data descriptive for first and second pictures captured in a first temporal distance to each other, a global motion estimator unit (110) estimates a global motion vector, which is descriptive for sign and amount of a global displacement of image portions that move with respect to a first axis both when the move at the same speed and when they move at different velocities. The global motion vector improves estimation of fast moving objects. The global motion vector estimation may rely on the evaluation of a plurality of one-dimensional profiles.
