  • Patent number: 10883861
    Abstract: An optical fiber distributed acoustic sensor system includes weak broadband reflectors inserted periodically along the fiber. The reflectors reflect only a small proportion of the light from the DAS incident thereon back along the fiber, typically in the region of 0.001% to 0.1%, but preferably around 0.01% reflectivity per reflector. In addition, to allow for temperate compensation to ensure that the same reflectivity is obtained if the temperature changes, the reflection bandwidth is relatively broadband. In some embodiments the reflectors are formed from a series of fiber Bragg gratings, each with a different center reflecting frequency, the reflecting frequencies and bandwidths of the gratings being selected to provide the broadband reflection. A chirped grating may also be used to provide the same effect. In preferred embodiments, the reflectors are spaced at half the gauge length i.e. the desired spatial resolution of the optical fiber DAS.

  • Patent number: 10884368
    Abstract: A protection member is arranged such that the distance from an opening plane of a reception guide to the center of the protection member is half of the distance from the opening plane of the reception guide to the surface of a reception vibration member. In other words, the arrangement position of the protection member is in the center between the opening plane of the reception guide and the surface of the reception vibration member. Accordingly, even if a protection member is arranged, a transmission coefficient is obtained that is equal to a transmission coefficient in the case where no protection member is present.

  • Patent number: 10739476
    Abstract: A seismic sensor that suppresses power consumption operates in a power-saving mode and a measurement mode in which the power consumption is larger than that in the power-saving mode. The seismic sensor includes a measurement unit that measures an acceleration, a filtering unit that, if the acceleration measured by the measurement unit exceeds a predetermined threshold, causes a shift from the power-saving mode to the measurement mode to be performed, and performs filtering on the measured acceleration, an earthquake determination unit that determines whether or not an earthquake has occurred based on the filtered acceleration, and an index calculation unit that, if where the earthquake determination unit determined that an earthquake has occurred, calculates an index value indicating the scale of the earthquake. A shift from the measurement mode to the power-saving mode is performed if the earthquake determination unit determined that no earthquake has occurred.

  • Patent number: 10684260
    Abstract: Ultrasonic transmitting elements in an electroacoustical transceiver transmit acoustic energy to an electroacoustical transponder, which includes ultrasonic receiving elements to convert the acoustic energy into electrical power for the purposes of powering one or more sensors that are electrically coupled to the electroacoustical transponder. The electroacoustical transponder transmits data collected by the sensor(s) back to the electroacoustical transceiver wirelessly, such as through impedance modulation or electromagnetic waves. A feedback control loop can be used to adjust system parameters so that the electroacoustical transponder operates at an impedance minimum. An implementation of the system can be used to collect data in a vehicle, such as the tire air pressure. Another implementation of the system can be used to collect data in remote locations, such as in pipes, enclosures, in wells, or in bodies of water.
