Abstract: System and method for enhancing audio reproduced by an audio reproduction device with a first channel and second channel is described. X samples of audio signals are received and stored in a portion of an input buffer with 2x positions and rest of the x positions are padded with zero for both the channels. Contents of the input buffer are transformed to frequency domain (FD) components. FD components are multiplied with a first filter coefficient to generate FD components with short echo effect and with a second filter coefficient to generate FD components with long echo effect. Then, they are converted to time domain (TD) components with short echo effect and TD components with long echo effect. Selective TD components with short echo effect and long echo effect are combined to generate a convolved first channel output and a convolved second channel output.

Abstract: Disclosed is a method for monitoring photovoltaic modules, which are used in an arrangement comprising several photovoltaic modules, which are connected in particular in series by means of electrical conducting means, wherein a separate microcontroller is associated with the respective photovoltaic module, an and in particular continual determination of at least one status parameter of the respective photovoltaic module is performed by the microcontroller, the data concerning the status parameter are transmitted to an evaluating unit, the data intended to be transmitted to the evaluating unit are designed in the form of data blocks, the electrical conducting means present for connecting the individual photovoltaic modules are used to transmit the data blocks, and the data blocks are transmitted independently of each other so that the probability of data blocks colliding with each other is greater than 0.

Abstract: A method for disconnecting a photovoltaic assembly, wherein the photovoltaic assembly includes the following: a string having a plurality of photovoltaic modules having a plurality of solar cells, an electrical line, which connects the individual photovoltaic modules to one another to form the string and serve the purpose of conducting the current produced by the individual solar cells in the photovoltaic modules to a common inverter. The photovoltaic assembly is disconnected by a disconnection signal in a hazard situation. Furthermore, in order to ensure increased safety in an emergency situation, provision is made for the disconnection signal to be conducted via the electrical line to the individual photovoltaic modules in the string, for the disconnection signal to be detected at the respective photovoltaic module and for the respective photovoltaic module to be disconnected via a switching device arranged at the respective photovoltaic module.

Abstract: The present invention relates to a method for monitoring photovoltaic modules (1, 2), which are used in an arrangement comprising several photovoltaic modules, which are connected in particular in series by means of electrical conducting means (3), wherein a separate microcontroller (5) is associated with the respective photovoltaic module (1, 2), an in particular continual determination of at least one status parameter of the respective photovoltaic module (1, 2) is performed by the microcontroller (5), the data concerning the status parameter are transmitted to an evaluating unit (10), the data intended to be transmitted to the evaluating unit (10) are designed in the form of data blocks (7, 8), the electrical conducting means (3) present for connecting the individual photovoltaic modules (1) are used to transmit the data blocks (7, 8), and the data blocks (7, 8) are transmitted independently of each other so that the probability of data blocks (7, 8) colliding with each other is greater than 0.
