  • Detecting responses of micro-electromechanical system (MEMS) resonator device
    Patent number: 8952891
    Abstract: A system for detecting responses of a MEMS resonator device includes first and second signal sources, a signal divider and a frequency mixer. The first signal source provides a first signal and the second signal source provides a second signal that electrostatically drives the MEMS resonator device, causing mechanical vibration. The signal divider divides the first signal into a probe signal and a local oscillator (LO) signal, the probe signal being applied to the MEMS resonator device and reflected by a capacitance of the MEMS resonator device. A reflection coefficient is modulated onto the reflected probe signal at the mechanical resonance frequency by variations in the capacitance induced by the mechanical vibration of the MEMS resonator device. The frequency mixer mixes the reflected probe signal and the LO signal and outputs an intermediate frequency (IF) signal, which represents modulation of the reflection coefficient, providing an image of the mechanical vibration.

  • Coaxial automatic impedance adaptor
    Patent number: 7936233
    Abstract: The invention concerns a coaxial automatic impedance adaptor characterized in that it comprises two slugs and has only a lateral translational movement along an axis Ox. The double slug tuner principle is based on the movement of two line segments of different characteristics of 50 O inside a closed cylinder on either side of standard connectors.

  • Compact automatic impedance adapter in a waveguide
    Patent number: 7795988
    Abstract: The invention relates to a compact automatic impedance adapter in a waveguide, characterised in that the impedance is controlled by plungers, filling the entire guide with a magic-tee coupler plane E/plane H modifying the electrical and magnetic field, one plunger modifying the electrical field (E) in the guide and the second modifying the magnetic field (H).
