摘要： An ultrasonic distance measure includes: transmitting and receiving ultrasonic transducers 1, 2 with changeable resonant/resonance frequencies; a driving section 151 generating a frequency-modulated drive signal to drive the transducer 1 and transmit an ultrasonic wave; a transmitting control voltage generating section 152 for generating a control voltage to change the resonant/resonance frequency of the transducer 1 and applying it to the transducer 1 in transmitting the ultrasonic wave; a receiving control voltage generating section 153 for generating a control voltage to change the resonant/resonance frequency of the transducer 2 and applying it to the transducer 2 when a controllable amount of time delay has passed since the drive signal was generated; and a receiving section 154 for sensing the intensity of a signal received as the ultrasonic wave at the transducer 2. The ultrasonic wave is transmitted from the transducer 1 toward an object a number of times, reflected, and then received at the transducer 2 with the time delay changed. The distance measure calculates propagation time of the ultrasonic wave based on the time delay that makes the receiving section receive the ultrasonic wave as a signal with the highest intensity, and measures the object's distance based on the propagation time.

摘要： A tracking system of the present invention includes a transponder 20 attached on a moving object 2 and an autonomous mobile unit 1 for tracking the transponder 20. The autonomous mobile unit 1 has an environment detecting means for acquiring reflection environment information relating to a wall surface 6a, 6b and 6c existing in the vicinity. In this system, the following tracking cycle is executed. The autonomous mobile unit 1 transmits a first ultrasonic wave, and upon receipt of it, the transponder 20 transmits a second ultrasonic wave. By receiving the second ultrasonic wave, the autonomous mobile unit 1 acquires reception information relating to a direct wave that directly arrives at the autonomous mobile unit 1 from the transponder 20 and a reflected wave that arrives via the wall surface. Using the reception information and the reflection environment information, the autonomous mobile unit 1 decides whether the received second ultrasonic wave is the direct wave or the reflected wave and processes the reception information based on the decision to estimate and track the position of the transponder 20.

摘要： An ultrasonic measuring method includes the steps of: receiving ultrasonic waves, which have been transmitted by a spread spectrum technique using mutually different codes, at first and second receivers, thereby generating first and second received signals, respectively; generating interference signals, of which the amplitudes are equal to or greater than respective threshold values, from the first and second received signals that have been despread with a code that has been used to spread any of the ultrasonic waves other than a desired one; removing the spread interference signals from the first and second received signals; calculating maximum correlation values between the first and second despread received signals for the respective threshold values; selecting one of the threshold values, at which the greatest one of the maximum correlation values has been obtained, as a threshold value for canceling interference; and calculating the propagation distance or propagation azimuth of the desired ultrasonic wave by the amount of time it has taken for the first and second received signals to arrive.

The flow volume of the fluid is measured by detecting a bidirectional-propagation time difference between the ultrasonic waves propagating in the propagation path.
