  • Patent number: 11389372
    Abstract: A method of modulating glandular secretions by administering acoustic shock waves to a reflexology zone has been discovered. In one preferred embodiment, a treatment method achieves one or more of a) modulating blood sugar levels, b) stimulating insulin production levels or c) normalizing A1C levels by administering acoustic shock waves to a reflexology zone or region of a patient. The treatment method further has the steps of: activating acoustic shock waves of an acoustic shock wave generator to emit acoustic shock waves; subjecting the reflexology zone to acoustic shock waves stimulating the pancreas to have a modulated response wherein the modulated response is one of an adjustment in blood sugar levels or insulin production and release or normalizing A1C levels which increases low level output, decreases high level output or stabilizes erratic output; and wherein the emitted acoustic shock waves are focused or unfocused.

  • Patent number: 11194038
    Abstract: A multistatic array topology and image reconstruction process for fast 3D near field microwave imaging are presented. Together, the techniques allow for hardware efficient realization of an electrically large aperture and video-rate image reconstruction. The array topology samples the scene on a regular grid of phase centers, using a tiling of multistatic arrays. Following a multistatic-to-monostatic correction, the sampled data can then be processed with the well-known and highly efficient monostatic Fast Fourier Transform (FFT) imaging algorithm. In this work, the approach is described and validated experimentally with the formation of high quality microwave images. The scheme is more than two orders of magnitude more computationally efficient than the backprojection method. In fact, it is so efficient that a cluster of four commercial off-the-shelf (COTS) graphical processing units (GPUs) can render a 3D image of a human-sized scene in 0.048-0.101 seconds.

  • Patent number: 11166632
    Abstract: A neuromodulator accurately measures—in real time and over a range of frequencies—the instantaneous phase and amplitude of a natural signal. For example, the natural signal may be an electrical signal produced by neural tissue, or a motion such as a muscle tremor. The neuromodulator generates signals that are precisely timed relative to the phase of the natural signal. For example, the neuromodulator may generate an exogenous signal that is phase-locked with the natural signal. Or, for example, the neuromodulator may generate an exogenous signal that comprises short bursts which occur only during a narrow phase range of each period of an oscillating natural signal. The neuromodulator corrects distortions due to Gibbs phenomenon. In some cases, the neuromodulator does so by applying a causal filter to a discrete Fourier transform in the frequency domain, prior to taking an inverse discrete Fourier transform.

  • Patent number: 10974078
    Abstract: Ultrasonic energy is used for treating degenerative dementia. A focal point of an ultrasonic transducer beam is directed at a target area of the brain to promote removal of substances that accumulate in the interstitial pathways that are at least partially responsible for the degenerative dementia. In one example, the target area of the brain may comprise the hippocampus and the degenerative dementia may be Alzheimer's disease. The ultrasonic beam may stimulate brain tissue at a frequency that corresponds to a naturally occurring deep sleep burst frequency of neurons and subsequent astrocyte activation patterns that drive a convective process responsible for brain solute disposal. For example, the transducer may generate a burst frequency of between 1-4 hertz to stimulate deep sleep brain functions that help remove amyloid plaque.

  • Patent number: 10959768
    Abstract: Systems and methods for facilitating treatment are disclosed that can include the use of imaging techniques in conjunction with one or more non-invasive techniques for modifying tissue, e.g., tissue in or around the spine. Depending on the type of treatment to be performed, various imaging modalities may be suitable for visualizing the tissue. Energy can be applied to tissue from outside of the body such that the tissue is modified in a non-invasive manner. For example, focused ultrasound can be used to dissect body tissues or can be applied to specific regions of tissue to change a characteristic of the tissue, e.g., increase its elasticity. The methods disclosed herein can be stand-alone treatments or can be performed prior to one or more surgical procedures. For example, non-invasive imaging and modification of body tissues can facilitate accessing the spine, preparing an interbody space, and/or surgically correcting the spine.

  • Patent number: 10898711
    Abstract: Described is system for mapping user behavior to brain regions of interest. Using a cognitive-behavior model, a behavioral task is selected that is suited for a desired brain state. Using a functional-anatomical model coupled to the cognitive-behavior model, a set of high-definition neurostimulations is selected to be applied to the user during performance of the selected behavioral task. The selected set of high-definition neurostimulations targets specific regions of the user's brain. Changes in the user's brain state are sensed during application of the set of high-definition neurostimulations and performance of the selected behavioral task using at least one brain monitoring technique. The coupled functional-anatomical and cognitive-behavior models are adapted until the desired brain state is reached.
