摘要:
An ultrasound transducer patch (100) comprises an array of ultrasound transducers (20) mounted to a flexi-PCB (10) containing multiple tracks (12). Each transducer (20), or a sub-group of the transducers is electrically connected to first and second of the multiple tracks. The flexi-PCB (10) is configured, such as by virtue of cut-out portions (114, 414) or by inherent elasticity, to be bendable a out non-parallel axes. The enables the patch (100) to readily conform to a complex 3D surface such as a portion of a patient's face to ensure efficient transmission of ultrasound energy to a desired area of treatment.

Components, such as a cutting element for an earth-boring drilling tool include an ultrasonic transducer coupled therewith, and configured to transmit an acoustic signal therethrough, and transmit a data signal to a data acquisition unit in response to receiving a returning echo of the acoustic signals. An earth-boring drilling tool, comprises a bit body including a plurality of components, an ultrasonic transducer, and a data acquisition unit operably coupled with the ultrasonic transducer. The data acquisition unit may be configured to receive the data signal and determine a temperature distribution of the component based, at least in part, on a time-of-flight of the acoustic signals and the returning echoes. Methods for forming such components and measuring a temperature of such components may relate to coupling and implementing such an ultrasonic transducer with a component of an earth-boring drilling tool.

An automated blade crawler capable of scanning a multiplicity of non-destructive inspection sensors over a surface of an airfoil-shaped body such as a blade component. The blade crawler is movable in a spanwise direction, thereby enabling a sensor array to inspect the surface area on one or both sides of the blade component in one pass. The sensors concurrently output scan imaging data which is multiplexed, the multiplexed being transmitted (via an electrical cable or wirelessly) to data collection and display hardware at an operations control center.

The present invention relates to a device for the passive reduction of the sound vibrations in a liquid resulting from a sound source arranged below the liquid level of a body of water, the device comprising an elongate tube which can be arranged over the sound source, the tube comprising an outer wall and inner wall, wherein the tube is designed to maintain a certain desired pressure in the intermediate space between the inner and outer wall. In this case, the pressure is reduced with respect to the ambient pressure. As a result of the reduced pressure, the sound vibrations will less readily travel to the outside and the noise level in the area around the tube is reduced.

Disclosed is a device and a casing therefor. The device comprises a casing having a back side and a casing opening in the back side; a speaker mounted inside the casing and in communication with the casing opening; and a cover shaped to mate with and to cover the casing opening, the cover having a first nub and a second nub and a speaker opening providing an air channel for the speaker. In the device, the first and the second nubs are located about the speaker opening in a symmetrical pattern; and when the communication device is placed on a flat surface with the side of the casing facing the flat surface, the first and second nubs cause the back side of the casing to be canted from the flat surface to expose the speaker opening to ambient air.

The ultrasonic sensor includes, on the same substrate, transmitter elements, receiver elements, a potential controller for receiver electrodes of the receiver elements, and a connection switching unit for the receiver electrodes and the potential controller. During the ultrasound transmission period of the transmitter elements, the connection switching unit connects the potential controller and the receiver electrodes. During the reception period of the receiver elements, the connection switching unit disconnects the potential controller and the receiver electrodes.
