Patents by Inventor Bernd EHRBRECHT

Bernd EHRBRECHT 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).

  • Publication number: 20240159696
    Abstract: Evaluation arrangement for a thermal gas sensor with at least one heater and at least one detector. The evaluation arrangement is configured to obtain information about an amplitude of a detector signal of a first detector, and information about a first phase difference between a heater signal and the detector signal of the first detector. In addition, the evaluation arrangement is configured to form as an intermediate quantity, dependent on the information about the amplitudes of the detector signal and dependent on the information about the first phase difference, a combination signal, and to determine information about a gas concentration or information about a thermal diffusivity of a fluid on the basis of the combination signal.
    Type: Application

  • Patent number: 11454622
    Abstract: Gas sensor, including a membrane and a heating element arranged on the membrane between a first discontinuation area of the membrane and a second discontinuation area of the membrane. The first discontinuation area of the membrane includes at least one discontinuation of the membrane and the second discontinuation area of the membrane includes at least one discontinuation of the membrane. The gas sensor further includes a first temperature sensor structure arranged at least partially on the membrane on a side of the first discontinuation area of the membrane opposite to the heating element, and a second temperature sensor structure arranged at least partially on the membrane on a side of the second discontinuation area of the membrane opposite to the heating element.
