  • Pressure transducer and method for fabricating the same
    Patent number: 10451508
    Abstract: A pressure transducer comprises a housing including a body section and at least one end cap at one end of the body section, which are made of piezoelectric crystal, and a piezoelectric resonator in the housing. The body section and the end cap are bonded by an atomic diffusion bonding method.

  • Systems and methods of determining parameter values in a downhole environment
    Patent number: 8534115
    Abstract: Systems and methods of determining parameter values in a downhole environment are described. An example method of determining a parameter value using calibration information is described. The calibration information corresponding to different parameter ranges in a downhole environment. The method includes determining a parameter range in the downhole environment using a controller and obtaining first calibration information or second calibration information based on the parameter range. The first calibration information associated with a first parameter range and the second calibration information associated with a second parameter range. The method also includes receiving an output signal from a sensor associated with the parameter and using the obtained calibration information to determine the parameter value based on the output signal received.
