Latest Patents

Hester holds a patent for "Testing of inductively loaded transmission lines for correct loading." This patent discloses equipment and methods for testing inductively loaded telephone lines for loading irregularities. In brief, immittance magnitude measurements are utilized to determine the approximate frequencies of the poles and zeros of such a line. Subsequently, a lossless ladder network comprising series inductors and shunt capacitors is synthesized, wherein the pole and zero frequencies of the network are substantially equal to those previously determined. The network inductor values relate to the line loading inductor values, while the network capacitor values relate to the distances between the loading inductors.
