Holger Wentzlaff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Pressure gauge, blood pressure gauge, method of determining pressure values, method of calibrating a pressure gauge, and computer program
    Patent number: 9119536
    Abstract: A pressure gauge for determining at least one pressure value describing a pressure of a fluid flowing in a pulsating manner in a phase of the pulsating flow, includes a pulse wave characterizer. The pulse wave characterizer is configured to obtain transmit time information of a pulse wave, and amplitude information of the pulse wave. The pressure gauge additionally includes a pressure value determiner configured to obtain a first pressure value describing a pressure of the fluid in a first phase, on the basis of the transmit time information and while using a mapping. The pressure value determiner is further configured to obtain a second pressure value describing a pressure of the fluid in a second phase, on the basis of the first pressure value and the amplitude information while using a mapping.
