  • Patent number: 10025123
    Abstract: The various technologies presented herein relate to various hybrid phononic-photonic waveguide structures that can exhibit nonlinear behavior associated with traveling-wave forward stimulated Brillouin scattering (forward-SBS). The various structures can simultaneously guide photons and phonons in a suspended membrane. By utilizing a suspended membrane, a substrate pathway can be eliminated for loss of phonons that suppresses SBS in conventional silicon-on-insulator (SOI) waveguides. Consequently, forward-SBS nonlinear susceptibilities are achievable at about 3000 times greater than achievable with a conventional waveguide system. Owing to the strong phonon-photon coupling achievable with the various embodiments, potential application for the various embodiments presented herein cover a range of radiofrequency (RF) and photonic signal processing applications. Further, the various embodiments presented herein are applicable to applications operating over a wide bandwidth, e.g. 100 MHz to 50 GHz or more.

  • Patent number: 10027706
    Abstract: To automatically identify an attempt at presenting falsified vehicle identifiers to portable devices, (i) a vehicle identifier reported by a vehicle with which the portable device is establishing a short-range communication link, and (ii) an indication of a current location of the portable device, are received from a portable device at a first time. An indication of a recent location at which the vehicle identifier was reported at a second time is obtained. The current location of the portable device is compared to the recent location of the vehicle, in view of the first time and the second time. In response to determining that the current location is not proximate to the recent reported location of the vehicle, an indication that the reported identifier is likely falsified is generated.
