Title: Method and device for preventing signal loss in unterminated bridge taps
Inventor: JEFFERY ROSS A
IPC: H04M1/76
Filed: 2001-10-05
Abstract: A method and device for avoiding signal cancellation caused by a unterminated bridge taps, provides a cable extension, preferably in the form of a pair of coils having an impedance matching the impedance of the telephone wire, respectively coupling the conductors in each bridge tap to the incoming ring and tip conductors. The cable extension increases the effective length of the bridge tap, thereby eliminating destructive interference between the incoming telecommunications signal and the signal reflected from the unterminated end. In the preferred embodiment the cable extension is adaptable to various lengths by a switching network.

Abstract: A highly conductive polymer based solid gel membrane is disclosed. The membrane is especially well-suited for use in such electrochemical devices a s metal/air, Zn/MnO2, Ni/Cd and hydrogen fuel cells, as well as in electrochromic devices such as smart windows and flat paneldisplays. Furthermore, in rechargeable electrochemical cells, the solid gel membrane i s highlyeffective for use as a separator between the anode and charging electrode. In accordance with the principles of the invention, the highly conductive membrane comprises a support or substrate and a polymeric gel composition having an ionic species contained in a solution phase thereof. T he polymer-based gel is prepared by adding an ionic species to a monomer soluti on followed by polymerization. After polymerization, the ionic species is embedded in the polymer-based gel where it remains. The ionic species behave s like a liquid electrolyte, while at the same time, the polymer-based solid g el membrane provides a smooth impenetrable surface that allows for the exchange  of ions. An advantage of the novel membrane is that its measured ionic conductivity is much higher than previously observed in prior art solid electrolytes or electrolyte-polymer films.
