Abstract
This invention provides an active solution for the problem of remote power feeding on only one pair of communication wires. The invention is an active system of one power transmitter and one or more power receivers. Unlike mains power distribution networks, in this invention, both power transmitter and power receivers maintain low impedance in the power pass band frequencies and high impedance in other communication bands with a sharp slop of impedance transition between bands. This behavior allows a parallel connection of the transmitters and receivers to an existing communication line with a negligible loading of communication signals. The system can be implemented with any type of pair of wires: twisted pair, parallel pair, coax etc. The power waveform can be either DC or AC, depending on the application and the other signals sharing the same pair of wires. The frequency of the power carrier will be set to an unused range of the spectrum for the following purposes: a. Minimizing interferences with other signals. b. Achieving high impedance at the frequency of the power carrier at all other devices connected to the pair of wires. An example for a typical use of the invention is an AC powering of a remote user device for supplying POTS, ISDN or ADSL services, through the existing pair of wires. The use of the said invention can power this device without interfering any of those services.

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.
