This study presents a precise method for monitoring shear crack development in concrete using acoustic emission analysis ...

Abstract: Coupled resonator filters designed using a single-layer coupler require coupling materials with an acoustic impedance less than 5.0 MRayl. Carbon-doped oxide, with an acoustic impedance of 4 ...

An embedded thermoacoustic engine (TAE) uses the resonance of a standing wave in the working medium to convert heat into acoustic energy. The proposed system was conceived with a direct-coupling ...

In this work, we present a device consisting of two coupled transmon qubits, each of which are coupled to an independent high-overtone bulk acoustic wave resonator (HBAR). Both HBAR resonators support ...

In a reciprocity calibration, two microphones are connected to each other via a small hollow cylinder called an acoustic coupler. One microphone produces a sound that the other microphone picks up.

Twenty-five years in the making, the Deep Space Resonance is a triple-axis tourbillon equipped with an acoustic coupling mechanism incorporating two balance wheels. But that description hardly ...

like an old-fashioned acoustic coupler for a telephone. Such instruments need power, though. And if they are sitting on the seabed, replacing their batteries is a serious chore. But Fadel Adib of ...

This vibration maximizes the electro-acoustic coupling, creating waves that are in phase over a wide area. In fact, because their wavelength (8 mm) roughly equals the diameter of the piezoelectric ...

A VPN is a viable option to get around the Great Firewall of China, but [agp] had a better idea: an acoustic coupler for his son’s iPhone. Hackaday readers of a recent vintage might remember an ...
