Abstract: A sonic ranging and/or object detection system, particularly useful for the blind, periodically employs widely different pulse frequencies in order to distinguish between objects located directly in front of the energy transmitting portion of this system and those located to either side. The higher frequency pulses produce a relatively narrow sonic energy beam width for detecting centrally located objects and the lower frequency pulses produce a relatively broad sonic energy beam width for detecting lateral or off-center objects. One or more time-related audible tones are superimposed on each of the pulse frequencies for range determining and/or object distinguishing purposes.

Abstract: In the measurement of the distance between two immersed points using ultrasonic signals, a control beacon is located at one point and a servo-beacon at the other point. The control beacon emits a first signal which is received by the servo-beacon. After a set period of time T sufficient for the disappearance of all echoes, the servo-beacon emits a signal which is received by the control beacon. Measurement apparatus associated with the control beacon determines the distance as a function of the time between emission of the first signal by the control beacon and reception of the signal from the servo-beacon, and the velocity of the ultrasonic signal which is determined in the region of the control beacon.

Abstract: A distance measuring apparatus installed in an automobile to measure with a high degree of accuracy a distance between a road surface and the axle of vehicle body of the automobile in motion. With this distance measuring apparatus, the distance between the point of its installation on the automobile and the road surface is measured by transmitting wave signals from the point of installation toward the road surface, selecting only the reflected wave signals of a predetermined intensity from the received reflected wave signals from the road surface and then integrating and averaging the data of the distance to the road surface derived from the selected reflected wave signals.

Abstract: A method and apparatus for indicating the level of liquid in a tank or the like whereby a transducer is mounted on a pipe above the liquid for producing, in response to a trigger signal, an ultrasonic pulse which is transmitted toward and reflected to the transducer first from a calibration target in the pipe above the liquid and then from the liquid so that the transducer produces echo pulses in response to receipt thereof. In one embodiment the calibration echo signal is applied to a logic circuit together with the output of a counter which is incremented to a predetermined count following the trigger signal by pulses from a voltage controlled oscillator so that the logic produces a control signal indicating the difference in time between when the calibration echo is received and when the counter reaches its predetermined count and which event occurs first. The logic then varies the frequency of the oscillator to reduce the difference. A further counter is enabled upon receipt of the calibration echo signal to accumulate a count of pulses from the oscillator and disabled upon receipt of the liquid echo signal so that the count indicates the liquid level.

Abstract: A depth sounding instrument including an oscillator for supplying AC energy to a transducer. The oscillator is keyed on by a multivibrator which produces clock pulses. Each clock pulses switches the state of a flip flop and starts a time measuring interval each time a clock pulse is supplied to the oscillator. A receiver receives the reflected sonic energy and terminates the time measuring interval of the flip-flop. A meter responds to the measured time interval to provide a visual indication of the depth from which energy was reflected.

Abstract: An acoustic range measuring device, utilizing an electronic counter to determine the number of pulses from a reference oscillator that occur in the time interval between the transmitting and return of an acoustic pulse from a transducer is capable of direct connection to digital computers and digital controllers and is provided with logic circuits to automatically check validity of the count and with other logic circuits to provide an output signal indicative of the distance from the transducer to an obstruction (an object or a solid or liquid material) in the path of the acoustic pulse if valid information has been received, or to provide a signal indicating that valid information has not been received. The device can be provided with a second transducer and electronic circuitry to automatically compensate, by changing the frequency of the reference oscillator, for any changes in the acoustic pulse velocity that might occur due to changes in temperature, humidity, pressure, etc., in the medium. The device may also be provided with electronic circuitry for producing an alarm signal if the measured distance is not within a pre-set range. Further, the device may be provided with logic and electronic circuitry enabling it to sequentially operate a multiplicity of transducers, and to provide an output signal for each of the transducers.

Abstract: A fathometer, for measuring the depth in water to a sloping bottom surface, includes a transmitter, periodically providing pulses in the water, and at least a pair of receivers arranged in a predetermined manner with the transmitter. Each receiver receives reflection pulses of the transmitted pulses from the sloping surface. Synchronizing pulses coinciding with the transmitted pulse and outputs from corresponding receivers control elapsed time circuits to provide signals corresponding to time intervals. Each time interval starts with the transmission of a pulse by the transmitter and the reception of a reflection pulse by a corresponding receiver. An analog computer provides outputs corresponding to the water''s measured depth and to the location of the depth measurement in accordance with the time interval signals and the known predetermined arrangement of the transmitter and the receivers. A recorder provides a record of the depth measurement and its proper location in accordance with the outputs from the analog computer.
