Abstract
A PC (10) connected to a low-voltage electricity supply system (9) via a mains plug (11) and a mains socket outlet (12), into which the said plug is plugged, exchanges messages with other apparatuses via the said electricity supply system by means of signals whose frequency is between 1 MHz and 40 MHz. In order to suppress high-frequency interference signals which are generated by further apparatuses which are connected to the low-voltage electricity supply system (9) via mains plugs (11') and further mains socket outlets (12'), arranged in local proximity to the said mains socket outlet (12), or which are produced by reflections of signals at open line ends, an adapter (1) is in each case interposed there, which adapter is plugged into the mains socket outlet (12') and into which adapter the mains plug (11') of the respective apparatus is plugged. The adapter (1) connects each pin of the mains plug (11') to a socket of the mains socket outlet (12'), inductor coils which block signals in the frequency range of the message transmission being situated, however, in the phase conductor and in the neutral conductor of the adapter (1).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
