Title: Innovations by Dieter Ehlers: Pioneering Capacitive Sensors and Data Communication Systems
Introduction
Dieter Ehlers, an accomplished inventor based in Muehlheim, Germany, has made significant contributions to the field of technology with two patented inventions. His work primarily focuses on enhancing the functionality and efficiency of capacitive measuring circuits and data communication systems.
Latest Patents
Dieter Ehlers holds two patents that showcase his inventive prowess. The first patent details a **circuit arrangement for evaluating the signal of a capacitive measuring system**. This innovative capacitive humidity sensor circuit utilizes a one-shot circuit that produces pulses. The duration of these pulses is determined by the capacitance of a capacitive sensing element, which is triggered by the trailing edges of pulses from a multivibrator. Notably, the multivibrator can generate a pulse train of variable repetition rates, independent of the measured parameter’s value. The integrated output of the one-shot circuit provides a voltage that indicates the time average of the pulses. This voltage is then processed through an amplification and offset compensation circuit, effectively countering the nonlinear response of the capacitive sensing element to varying relative humidity levels.
Ehlers' second patent focuses on a **data communication system** that utilizes a three-wire bus to connect a central station with multiple substations. In this system, two wires carry an AC supply voltage while the third wire transmits data using a closed loop established between the AC-carrying wires. The central station features a series connection of a data transmitter and a receiver linked to the third wire. Each substation contains a data receiver in series with the data wire, along with a data transmitter positioned between the data wire and both AC wires, facilitating an efficient communication framework.
