Latest Patents

Hafner's latest patents include a groundbreaking invention titled "Compensation for an ultrasonic transducer with a variable compensation inductance." This patent describes an ultrasonic transducer equipped with a piezoelectric element designed for use in vehicles. The transducer features a control and evaluation circuit that generates a control voltage for the piezoelectric element, which in turn emits an ultrasonic signal. Additionally, it outputs an echo signal received at the piezoelectric element. A key component of this invention is a gyrator circuit that provides a variable compensation inductance, allowing for adaptation to the parasitic connection capacitance of the piezoelectric element. Furthermore, the patent outlines a method for compensating the ultrasonic transducer to enhance reception sensitivity by adjusting the compensation inductance based on recorded measurement variables.

Another significant patent by Hafner is the "Method and analysis system for determining a state of a diaphragm of an ultrasound sensor." This invention details a method for assessing the condition of a diaphragm in an ultrasound sensor during operation. The diaphragm is excited with a first excitation signal, and a corresponding voltage profile is measured. A second voltage profile is obtained through a different excitation signal, and both profiles are aligned to determine a third voltage profile. This third profile is then used to derive electrical parameters that indicate the diaphragm's state.
