Title: The Innovations of Charles Pohlenz
Introduction
Charles Pohlenz is a notable inventor based in Six Fours Les Pages, France. He has made significant contributions to the field of electro-acoustic transducers, holding a total of 2 patents. His work has advanced the technology used in sonar systems and other applications.
Latest Patents
Pohlenz's latest patents include a Tonpilz type piezoelectric transducer capable of operating alternately. This innovative transducer can function as both a wide-band receiver and an emitter. It consists of a stack of pairs of piezoelectric segments separated by electrodes, positioned between a horn and a countermass. An emitter is connected to one of the two electrodes for each segment pair, with one pair of segments next to the countermass being isolated by an insulator. The two electrodes on either side of this pair are connected in parallel to a receiver and, through two diodes connected in opposition, to a grounded common conductor.
Another significant patent is for electro-acoustic transducers. This invention also follows the Tonpilz design, featuring a stack of piezoelectric plates placed between a horn and a countermass, with electrodes inserted between the plates. Some electrodes are linked to a common excitation or output conductor through phase-shifting circuits, allowing for the electric voltage of a portion of these electrodes to be dephased. A logic unit enables the distribution of phase-shifting within the stack based on various groupings depending on frequency. This technology has applications in the construction of long-range power sonars.
