  • Patent number: 9970276
    Abstract: A system and method are provided that use RF energy to enhance the extraction of oil and gas from hydrocarbon bearing strata. A three-dimensional underground electromagnetic array is used to guide RF energy to where that energy is converted to heat in the hydrocarbon bearing strata.

  • Patent number: 9973170
    Abstract: In a high-frequency module, a phase and amplitude of a high-frequency signal from a connection conductor between filter devices change due to the signal being transmitted by a takeout circuit unit. When the high-frequency signal at a third external connection terminal is a suppression signal and a high-frequency signal passing through the first filter circuit is a suppression-target signal, the transmission distance in the takeout circuit unit is such that the phase of the suppression signal is approximately inverted with respect to the phase of the suppression-target signal and the suppression signal has approximately the same amplitude as the suppression-target signal. The suppression signal is mixed with the suppression-target signal and components outside of the pass band are cancelled out and the attenuation characteristics of the filter circuit are enhanced.

  • Patent number: 9954264
    Abstract: A cavity filter and a RF communication device including the cavity filter are disclosed. The cavity filter includes a cavity body, a cover plate, a resonance rod, a tuning screw, and a supporting member. The cover plate caps the cavity body to form a resonance cavity. The resonance rod is a tube with an opening at one end, where the opening end is combined with the cover plate or the cavity body. The supporting member is mounted to the cover plate or the cavity body to further secure the tuning screw to the resonance rod, and pushes the tuning screw along an axial direction of the resonance rod against the bottom end of the resonance rod, so as to make the resonance rod undergo an elastic deformation and thus adjust the RF parameters of the cavity filter.

  • Patent number: 9941857
    Abstract: A spur cancelling, electromechanical filter includes a first resonator having a first resonant frequency and one or more first spurious responses, and it also includes, electrically connected to the first resonator, a second resonator having a second resonant frequency and one or more second spurious responses. The first and second resonant frequencies are approximately identical, but the first resonator is physically non-identical to the second resonator. The difference between the resonators makes the respective spurious responses different. This allows for filters constructed from a cascade of these resonators to exhibit reduced spurious responses.
