  • Gas sensor
    Patent number: 8038933
    Abstract: A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.
    Type: Grant
    Filed: July 26, 2007
    Date of Patent: October 18, 2011
    Assignee: Robert Bosch GmbH

  • Structural body having a stochastic surface patterning as well as a capacitive sensor having such a structural body
    Patent number: 6515491
    Abstract: A structural body which, at least region-wise, has at least one area which is in contact with a liquid or a gas flowing past, and which, at least to a great extent, is provided with a surface patterning made of a plurality of randomly or irregularly distributed geometric forms, in particular pyramids. At least one such structural body be used in a capacitive sensor with which, in particular, the dielectric constants or the conductance of a liquid or a gas can be determined.
