The LEDs in a phototherapy LED pad are controlled so that the intensity of the light varies in accordance with a sinusoidal function, thereby eliminating the harmonics that are generated when the LEDs are pulsed digitally, in accordance with a square-wave function. This is accomplished analogically by using a sinusoidal wave to control the gate of a MOSFET connected in series with the LEDs or by using a digital-to-analog converter to control the gate of the MOSFET with a stair step function representative of the values of a sinusoidal function at predetermined intervals. Alternatively, pulse-width modulation is used to control the gate of the MOSFET in such a way that the average current through the LEDs simulates a sinusoidal function. In additional to using a simple sine wave function, the LED current may also be controlled in accordance with chords containing multiple sine waves of different frequencies.

An implantable vestibular prosthesis system includes an implantable optical array of optical sources configured for engagement with a disordered vestibular system to deliver optical stimulation signals to target stimulation locations within the bony or membranous labyrinth of the disordered vestibular system. An implantable stimulation processor is connected to the optical array and configured to produce the optical stimulation signals with the optical sources so as to generate directional pressure waves within the endolymphatic fluid directed to the target stimulation locations for vestibular perception by residual vestibular functioning.

Systems and methods of the present disclosure are directed to systems and methods for treating cognitive dysfunction in a subject in need thereof. The system can include a neural stimulation system that receives an indication of an ambient audio signal detected by a microphone. The system selects, from a profile, an audio signal including a fixed parameter and a variable parameter. The system sets the variable parameter to a first value. The system generates an output signal based on the fixed parameter and the first value, and provides the output signal to the speaker. The system measures a physiological condition of the subject, adjusts the variable parameter to a second value, generates a second output signal based on the fixed parameter and the second value of the variable parameter, and provides the output signal to the speaker to cause the speaker to provide modified sound to the subject.

The present invention is directed to a system and method for photoeradication of microorganisms from a target. The target is irradiated with pulsed purple or blue light in which (a) the light pulses have a peak irradiance and a pulse duration sufficient to optically excite a photoactive molecule capable of photoeradication of the microorganisms and (b) the light pulses are separated by an off time sufficient to allow the photoactive molecule to return to a ground state creating an oxidation reaction that produces free radicals which destroy a cellular structure of the microorganisms and thereby photoeradicate all or a portion of the microorganisms. The photoactive molecule may comprise either an endogenous molecule present in the microorganisms or an exogenous molecule applied to the target.

Systems and methods of the present disclosure are directed to systems and methods for treating cognitive dysfunction in a subject in need thereof.
