  • Publication number: 20200384292
    Abstract: Improved acoustic neurostimulation is provided by having two or more acoustic transducers generate an acoustic interference pattern in a region of a patient being treated. The apparatus has at least two operating modes it can switch between. A first operating mode has the transducers driven at the same frequency. A second operating mode has the transducers driven at different frequencies. Full control of the acoustic transducers allows the acoustic interference pattern to be varied electronically at will.

  • Publication number: 20200209029
    Abstract: Clamp-on ultrasonic flow metering is provided by collectively exciting and receiving circumferential modes of the pipe. The pipe wall supports an infinite number of circumferential acoustic resonances. Each of these modes, in contact with a fluid, can mode-convert into the flow at a different rate. The mode-converted waves in the flow mode-convert back into the circumferential waves in the pipe once they travel across the flow. Furthermore, the moving fluid alters the rate of mode-conversion as a function of the flow velocity. At low frequencies, the wavelength is larger, thus the penetration depth in the flow is larger. As the frequency increases, the penetration depth becomes smaller. The variable penetration depth provides a methodology to sample the flow velocity profile.

  • Publication number: 20200056917
    Abstract: Propagation of leaky Lamb waves in pipe walls is used to provide a clamp-on acoustic flow meter for single-phase fluid flow in pipes. The received acoustic signals can be analyzed analytically, or by matching to numerical models, or with machine learning. In a preferred embodiment, variation of penetration depth of the leaky Lamb waves into the fluid flow with frequency provides an approach for measuring flow rate vs. radius with a clamp-on flow meter.

  • Publication number: 20180280735
    Abstract: We provide a novel technique for coupling focused ultrasound into the brain. The ultrasound beam can be used for therapy or neuro-modulation. We excite a selected Lamb wave mode in the skull that mode converts into longitudinal waves in the brain. The benefits of our approach is in improved efficiency, reduction in heating of the skull, and the ability to address regions in the brain that are close or far from the skull.

  • Publication number: 20180101255
    Abstract: A method of multi-touch detection on a touchscreen by imparting Lamb waves inside a touchscreen, using a first ultrasound transducer having a polarization direction positioned to excite lowest order symmetric Lamb waves (S0), detecting the S0 Lamb waves, using a second ultrasound transducer, where the transducers are connected to the touchscreen, controlling the transducers to selectively and repeatedly pulse the output S0 Lamb waves output to propagate the S0 Lamb waves inside the touchscreen and reflect from each edge of the touchscreen to form a base signal distribution of S0 reverberant Lamb waves across the touchscreen, where a single or a multi-touch perturbation in the reverberant Lamb waves absorbs a portion of the base signal, where the absorption forms an alteration in the base signal and is seen as a signal variation by the controller when received by the second ultrasound transducer, where the controller identifies and locates the perturbation.
