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.

Method, sensor and system for analyzing appliances in a power line network

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, extracting a line-neglecting feature from the electrical characteristic of the power line network, and detecting an appliance connected to the power line network based on the extracted line-neglecting feature.

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.

A method for determining a processed audio signal, comprising: establishing an ad-hoc network between a plurality of handheld devices, each handheld device having a microphone; picking up a plurality of audio signals with each microphone of the plurality of handheld devices; distributing the plurality of audio signals within the ad-hoc network such that in at least one handheld device at least two of the plurality of audio signals are available; combining, in said at least one handheld device, the at least two of the plurality of audio signals to obtain said processed audio signal.

Method for determining a processed audio signal and a handheld device

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.

Method for discriminating textures regions and homogeneous or flat regions in an image and methods for estimating noise in an image sequence

A method for processing digital image data (ID) is proposed wherein a step (B) of processing digital image data (ID) comprises or realizes a sub-step (B') of image improvement with respect to said digital image data (ID) which uses or which is based on a process of re-mapping (REM) together with a process of dithering (DIT).

Method for processing digital image data

A method for pre-processing block-based digital data that pre-processes each digital pixel based on a respective data filter arrangement or data filter matrix for a respective data pixel within at least one data block and selects, constructs, and/or supplies the data filter arrangements or data filter matrices. The method is based on operations of data shifting and/or register shifting only.

Method for pre-processing block based digital data

A method for synchronizing video signals is provided wherein a synchronization state signal is generated which is descriptive for the synchronization of an output of fields/frames with the respective input of respective fields/frames of an underlying video data screen in particular on the basis of a time difference which is given by respective counted times and/or temporal changes and/or variations thereof.
