    摘要: Apparatus for performing multiple different measurements on a small specimen sample, enabling testing and diagnoses in real time at the point of care are described. The core of the apparatus includes an ultrasonic resonator cavity where acoustic resonances are used to determine the speed of sound and sound attenuation in a single droplet. Acoustic measurements are made in the reflection mode using electrical impedance of a small piezoelectric crystal transducer that operates in the thickness longitudinal mode. Combination of this technology with electromagnetic, electrical, and magnetic fields permits multiple types of measurements to be made using the same resonator cavity.

    摘要: Provided are systems and methods for line volume calibration, and measurement of fluid samples delivered to an interrogation point. In various embodiments, a known fluid volume comprising a sample line fluid and a secondary fluid is delivered to a fluid boundary sensor. The fluid boundary sensor assists in determining the position of the boundaries between the various fluids, and the positions of these boundaries are used to determine the sample line fluid volume.

    摘要: A spot-welding electrode assembly includes an electrode, an electrode cap at an outer end of the electrode, and a plurality of transducer elements positioned inward of the electrode cap. The transducer elements may be micro-elements. A method for monitoring a weld formed by a spot-welder includes passing current from an electrode assembly through a stack-up, transmitting an ultrasonic wave from each of a plurality of sources in the electrode assembly to a plurality of points in the stack-up, and monitoring the ultrasonic waves to monitor the weld formation.

    摘要: An ultrasound probe assembly comprises a housing and a wedge, wherein wedges configured for pipes of different diameter may be easily interchanged in the assembly. Four wheels are attached to the housing, there being a front wheel pair and a rear wheel pair. Wheels of each pair are positioned on either side of a linear probe array, wherein the distance between wheels in each pair in a direction perpendicular to the array length is as small as possible. A position encoder monitors the position of the assembly during scanning, and a push lock switch is used to disable the encoder and the data acquisition while indexing to a new scan position on the pipe.

    摘要: An ultrasonic sensing device includes a housing, a piezoelectric assembly, a board and a plurality of fixing members. The housing includes a connecting board being a metal board and a supporting shell being a plastic member. The supporting shell includes a bottom wall opposite to a disposing opening of the connecting board and a surrounding side wall integrally surrounding and connecting to the bottom wall. The surrounding side wall encloses a portion of the connecting board. The piezoelectric assembly includes an encapsulating body and a piezoelectric sheet enclosed by the encapsulating body. The encapsulating body is disposed on the bottom wall and surrounded by the surrounding side wall. The piezoelectric sheet has a sensing surface exposed to the encapsulating body and facing the bottom wall. The fixing members fix the board on the connecting board, thereby pressing the sensing surface of the piezoelectric sheet to the bottom wall.
