  • Patent number: 10145713
    Abstract: The optical fiber sensor device comprises a probe light supply unit, an optical fiber sensor unit, and a polarization state measuring unit. The probe light supply unit generates and outputs a polarization switched light beam by alternately switching a polarized CW light beam in polarization directions orthogonal to each other with elapse of time. The optical fiber sensor unit includes a loop-state optical fiber into which the polarization switched light beam is input and which outputs a light wave reflecting a change of birefringence according to a stress applied from an outside in the polarization switched light beam. The polarization state measuring unit observes polarization states of the respective light waves propagating clockwise and counterclockwise through the optical fiber.

  • Patent number: 10090882
    Abstract: In an echo suppressing apparatus suppressing from a near-end input signal acoustic echo signals caused by a far-end signal, an estimated-echo path characteristic is multiplied by a far-end signal to produce an estimated-echo signal for each frame, and frames of the estimated-echo signals thus obtained are stored in an estimated-echo signal storage. A delay amount estimator calculates the total of differences between the near-end input signal and each estimated-echo signal thus stored, and determines the amount of frame delay having its total of differences minimal. A delay estimated-echo signal calculator uses the amount of frame delay to read out an optimum frame and near frames respectively preceding and following the optimum frame and to calculate a corrected, delay estimated-echo signal. An echo suppressor uses the estimated-echo signal thus corrected to suppress the acoustic echo signals from the near-end input signal.

  • Patent number: 10029881
    Abstract: The present invention provides a medium processing device and medium transaction device that may increase stability by shortening a conveyance path. Namely, a banknote deposit/withdrawal device includes a conveyance section that forms a linear conveyance path along a front-rear direction inside an upper section block, in the vicinity of a boundary with a lower section block. An upper section storage box is disposed in the vicinity of a rear side terminal end of a rear conveyance section. Counterfeit notes are conveyed to the upper section storage box using a switching section. Accordingly, due to keeping the conveyance path length short, the banknote deposit/withdrawal device may reduce the frequency of occurrence of faults, such as banknote jams, and may prevent the circulation of counterfeit notes by storing counterfeit notes segregated from genuine banknotes, reject banknotes, and the like.
