Abstract
A method for providing electrical stimulation to a user, the method comprising: providing an electrical stimulation device, in communication with a controller, at a head region of the user; with the electrical stimulation device, providing a stimulation treatment having a waveform configured for neuromodulation in the user; with the controller, performing an adjustment to the stimulation treatment, wherein performing the adjustment includes: generating a transformed waveform with application of a transfer function to the waveform, wherein the transfer function scales the waveform and selectively attenuates extreme waveform values while maintaining a frequency characteristic of the waveform in the transformed waveform; and applying the transformed waveform with the electrical stimulation device, thereby modulating the stimulation treatment.
Core Innovation
An electrical stimulation device is provided at a head region of a user, and a stimulation treatment is delivered with a waveform configured for neuromodulation. The waveform includes a superposed waveform including superposition of two or more components, and at least one component comprises a frequency below 625 Hertz.
A transformed waveform is generated by applying a transfer function to the waveform, wherein the transformed waveform is configured for neuromodulation in the user. The transfer function adjusts the waveform, and the transformed waveform is applied with the electrical stimulation device to modulate the stimulation treatment.
The transfer function transforms an initial waveform by scaling and selectively attenuating extreme waveform values or transients while preserving a characteristic or frequency characteristics of the waveform in the transformed waveform. The system further supports a stimulation treatment time window and safety limits using neurological signatures, neurological metrics, and biological or threshold condition comparisons.
Claims Coverage
The partial set includes two independent claims. Each claim centers on electrical stimulation for neuromodulation using a superposed waveform including at least one component below 625 Hertz, with a transformed waveform determined by applying a transfer function; one claim further includes near-real time generation in response to an adjustment to the stimulation treatment.
Near-real time transformed neuromodulation waveform from superposed components
Providing an electrical stimulation device at a head region; providing a stimulation treatment having a waveform configured for neuromodulation as a superposed waveform including superposition of two or more components with at least one component comprising a frequency below 625 Hertz; determining an adjustment; in near-real time and in response to the adjustment, generating a transformed waveform with application of a transfer function to the waveform; and applying the transformed waveform to modulate the stimulation treatment in near-real time.
Transformed neuromodulation waveform determined from initial superposed waveform with transfer function
Providing an electrical stimulation device at a head region; providing a stimulation treatment having a transformed waveform configured for neuromodulation determined from an initial waveform comprising a superposed waveform including superposition of two or more components with at least one component comprising a frequency below 625 Hertz; determining the transformed waveform by applying a transfer function to the initial waveform; and applying the transformed waveform with the electrical stimulation device.
Across the independent claims, the core claimed structure is neuromodulation via an electrical stimulation device at a head region using a waveform formed from a superposed multi-component signal, where a transformed waveform is determined by applying a transfer function and is then applied for neuromodulation. One independent claim additionally specifies near-real time generation in response to an adjustment to the stimulation treatment.
