Title: Sven Wiklund: Innovator in Telephone Network Technology
Introduction
Sven Wiklund is a notable inventor based in Upplands Vasby, Sweden. He has made significant contributions to the field of telecommunications, particularly in the generation of ringing signals in telephone networks. His innovative approach has led to the development of a unique patent that enhances the efficiency of communication systems.
Latest Patents
Wiklund holds a patent for a "Method and apparatus for generating a ringing signal." This invention involves generating a ringing signal of predetermined frequency and shape between the A- and B-wires to a subscriber's station in a telephone network. The method directly injects the ringing signal into the DC-levels of the wires. A voltage difference converting device is utilized to convert any voltage difference between the A- and B-wires into a first current. A signal generating device then creates a first voltage of the desired frequency and shape, which is subsequently converted into a second current. The first current is subtracted from the second current in a summation node to obtain a third current, which is then processed through a resistor to produce a second voltage. This voltage is buffered and converted to a fourth current, which is amplified by current amplifier circuits comprising operational amplifiers, ultimately supplying the A-wire and drawing from the B-wire. He has 1 patent to his name.
