Implementations of the present invention relate to apparatuses, systems, and methods for blocking, attenuating, or filtering neuroactive wavelengths of the visible light spectrum and reducing or preventing the symptoms affiliated with exposure to those wavelengths. Nanoparticles of a predetermined composition, size, and structure are dispersed in a host medium to create an optical notch filter, thereby attenuating only a narrow range of the visible spectrum.

Nanoparticle light filtering method and apparatus

An optical filter may reduce the frequency and/or severity of photophobic responses or for modulating circadian cycles by controlling light exposure to cells in the human eye in certain wavelengths, such as 480 nm and 590 nm, and a visual spectral response of the human eye. The optical filter may disrupt the isomerization of melanopsin in the human eye reducing the availability of the active isoform, whereas the attenuation of light weighted across the action potential spectrum of the active isoform attenuates the phototransduction cascade leading to photophobic responses. Embodiments of an optical filter are described. In one embodiment an optical filter may be configured to transmit less than a first amount of light in certain wavelengths, and to transmit more than a second amount of light weighted across the visual spectral response. Methods of use and methods of manufacturing optical filters are also described.

Methods, systems, and apparatus for modulating or reducing photophobic responses

Systems and methods for measuring changes in smart hydrogel microresonator structures positioned in an in vivo or other environment, having an acoustic resonance frequency in an ultrasound range. The system includes a smart hydrogel microresonator structure positioned within the environment configured to exhibit a change in resonance frequency in response to interaction with one or more predefined analytes in the environment. The system includes an ultrasound transducer for querying the smart hydrogel microresonator structure at or near its resonance frequency. The system also includes a computer system configured to receive ultrasound data as provided by query of the smart hydrogel microresonator structure and to determine changes in resonance frequency, amplitude or intensity of the ultrasound query wave, or mean grayscale value (MGV) associated with the ultrasound data of the smart hydrogel microresonator structure due to the change in resonance frequency. Such change can be correlated to concentration of the analyte.

Ultra-compact inductor devices for use in integrated circuits (e.g., RF ICs) that use 3-dimensional Dirac materials for providing the inductor. Whereas inductors currently require significant real estate on an integrated circuit, because they require use of an electrically conductive winding around an insulative core, or such metal deposited in a spiral geometry, the present devices can be far more compact, occupying significantly less space on an integrated circuit. For example, an ultra-compact inductor that could be included in an integrated circuit may include a 3-dimensional Dirac material formed into a geometric shape capable of inductance (e.g., as simple as a stripe or series of stripes of such material), deposited on a substantially non-conductive (i.e., insulative) substrate, on which the Dirac material in the selected geometric shape is positioned. Low temperature manufacturing methods compatible with CMOS manufacturing are also provided.

The present disclosure describes systems, methods, and apparatus for reducing the frequency and/or severity of photophobic responses or for modulating circadian cycles by controlling light exposure to cells in the human eye in certain wavelengths, such as 480 nm and 620 nm, and a visual spectral response of the human eye. Embodiments of an optical filter are described. In one embodiment an optical filter may be configured to transmit less than a first amount of light in certain wavelengths, and to transmit more than a second amount of light weighted across the visual spectral response.
