  • Publication number: 20220158602
    Abstract: Frequency stabilization is provided in a microelectromechanical systems (MEMS) oscillator via tunable internal resonance (IR). A device comprises a MEMS resonator comprising a stepped-beam structure that is a thin-layer structure. The resonator may be configured to implement IR. The stepped-beam structure may be configured to provide flexibility to adjust modal frequencies into a n:m ratio, wherein n and m are integers. The thin-layer structure provides frequency tunability by controlling the mid-plane stretching effect with an applied DC bias. The thin-layer structure compensates for a frequency mismatch from a n:m ratio due to a fabrication error. The MEMS resonator may be an oscillator.

  • Patent number: RE49357
    Abstract: A method and system in which upon occurrence of a P-CSCF failure, a network sends an IMS reregistration request message to a UE. An S-CSCF or an AS monitors a P-CSCF to detect occurrence of a failure in the P-CSCF. Upon detecting the occurrence of a P-CSCF failure, the S-CSCF or the AS sends a request message for IMS reregistration to the UEs being served by the failed P-CSCF. In this manner, the UE can continuously receive the service even though a failure occurs in the P-CSCF.
