  • FREQUENCY VARIATION REDUCTION FOR ELECTROACOUSTIC DEVICES
    Publication number: 20260180547
    Abstract: Techniques and apparatus for designing and fabricating an electroacoustic device. One example method of fabricating an electroacoustic device generally includes forming a layer stack and forming an electrode structure above the layer stack. Forming the layer stack may include forming at least a portion of the layer stack with a thickness based on a positive slope of a function of a metallization ratio of the electrode structure versus the thickness of the at least the portion of the layer stack.

  • Apparatus for ascertaining and/or monitoring fill level and/or flow of a medium
    Patent number: 7861600
    Abstract: An apparatus for ascertaining and/or monitoring fill level and/or flow of a medium in a containment, including: at least one antenna, which radiates and/or receives high frequency signals according to a predetermined radiation characteristic along a main radiating axis in the direction of the surface of the medium; a control/evaluation unit, which evaluates the reflected high frequency signals and determines fill level on the basis of the travel time of the high frequency signals and/or flow on the basis of a Doppler frequency of the reflected high frequency signals; and at least one lens located between the antenna and the medium and having a first focal length in the direction of the antenna and a second focal length in the direction of the medium.
