Latest Patents

Zachary Fisk holds a patent for a resonant ultrasound spectrometer. This device determines the resonant frequency spectrum of a rectangular parallelepiped sample of a high dissipation material over an expected resonant response frequency range. The spectrometer features a sample holder structure that grips the corners of the sample between piezoelectric drive and receive transducers. Each transducer is mounted on a membrane to weakly couple the transducer to the holder structure, effectively contacting a material that removes system resonant responses at the transducer from the expected response range. The design includes a square-law detector amplifier that receives the response signal and retransmits it on an isolated shield of connecting cabling, eliminating cabling capacitive effects. This amplifier also provides a substantially frequency-independent voltage divider with the receive transducer. The sensitivity of the spectrometer allows for the detection of low amplitude resonance, which is crucial for calculating the elastic constants of high dissipation samples.
