Title: Frank Frungel: Innovator in Underwater Fluorometry

Introduction

Frank Frungel is a notable inventor based in Hamburg, Germany. He has made significant contributions to the field of underwater measurement technology. His innovative approach has led to the development of a unique patent that enhances the capabilities of fluorometric analysis in deepwater environments.

Latest Patents

Frank Frungel holds a patent for a device known as the Deepwater in-situ fluorometer. This invention features an onboard power supply and metering unit connected via an overboard cable, which can extend up to 1000 meters. The system includes an underwater light-pulse projecting unit and a fluorescence-sensing receiver unit. The operating power is transmitted to the underwater units by an onboard constant-current source, rather than a voltage source. The output signal from the receiver unit is also transmitted through the cable in the form of a current. The current from the receiver's photodiode is integrated, and the peak value is determined and held. This value is logarithmized, sampled, and converted to a current that constitutes the output signal. The system features automatic balancing of the peak detector and input stage of the log amplifier, ensuring accurate measurements.
