20200264136 | PROPAGATION TIME MEASUREMENT MACHINE, GAS CONCENTRATION MEASUREMENT DEVICE, PROPAGATION TIME MEASUREMENT PROGRAM, AND PROPAGATION TIME MEASUREMENT METHOD - A processor is configured to include a correlation object determination unit for establishing: a first to-be-correlated signal established on the basis of a first upper-limit rate of change, which is the rate of change of an upper-limit envelope of a direct wave signal, and a first lower-limit rate of change, which is the rate of change of a lower-limit envelope of the direct wave signal; and a second to-be-correlated signal established on the basis of a second upper-limit rate of change, which is the rate of change of an upper-limit envelope of a round-trip-delayed wave signal, and a second lower-limit rate of change, which is the rate of change of a lower-limit envelope of the round-trip-delayed wave signal. The processor is also configured to include a correlation processing unit for establishing a correlation value between the first to-be-correlated signal and a signal based on the second to-be-correlated signal. | 2020-08-20 |
20200264137 | ELECTRO-ACOUSTIC SENSORS FOR REMOTE MONITORING - 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. | 2020-08-20 |
