    Abstract: An application relates to a system and a method for non-intrusive and continuous level measurement in a cylindrical vessel. The system comprises an ultrasonic transducer for generating an ultrasound wave and for emitting it into the vessel wall, and an electronic control and data processing unit (ECDP) for controlling operation of the transducer and for determining the liquid level from a time of flight of the ultrasound wave. The transducer emits the ultrasound wave as a primary Lamb wave into the vessel wall so that a part of the primary Lamb wave leaks into the liquid. The ECDP changes the ultrasonic frequency of the transducer until the transducer receives a reflection of the emitted ultrasound wave in form of a reflection of the pressure wave, determine the corresponding time of flight, and determine the liquid level from the time of flight and from parameters of the ultrasound waves.

    Abstract: A transducer for non-invasive measurement includes: a piezoelectric element; a base plate; and driver electronics. The piezoelectric element is mounted to a first face of the base plate. A second face of the base plate is mountable to a wall of a vessel that holds a liquid. The driver electronics drive the piezoelectric element at a plurality of activation frequencies. When the second face of the base plate is mounted to the wall of the vessel, the transducer when activated excites acoustic waves in the base plate and to launch an acoustic wave into the liquid. The transducer is designed such that an angular divergence of the acoustic wave launched into the liquid varies as a function of at least the activation frequency and a dimension of an emitter.

    Abstract: It is provided a system for localizing a sound source and a method therefor. The system includes a movable unit, being adapted for free movement and being integrated with a microphone; a motion tracking unit; and a processing unit, being adapted for receiving microphone signal and motion tracking unit signal and obtaining information on a direction from which sound from the sound source arrives using the microphone signal and motion tracking unit signal obtained during movement of the movable unit. By having the system and the method therefor, it is helpful for solving at least one of the technical problems: the complexity and a large volume of an acoustic camera for localization of a sound source; the restriction of the movement of the microphone in a sound source localization system.

    Abstract: A system and a method for non-intrusive and continuous level measurement of a liquid enclosed by a solid wall of a vessel. The system comprises an ultrasonic transmitter for generating an ultrasound wave and for emitting it into the vessel wall, an ultrasonic receiver for receiving the ultrasound wave, and an electronic control and data processing unit (ECDU) for controlling operation of the transmitter and of the receiver and for determining the liquid level. The transmitter is able to emit the ultrasound wave as a primary Lamb wave into the vessel wall so that a part of the primary Lamb wave leaks from the vessel wall into the liquid in form of a pressure wave. The ECDU is adapted to repeatedly determine the time of flight of the pressure wave, change the ultrasonic frequency of the transmitter until the determined time of flight reaches a minimum, and determine the liquid level.
