Abstract: The present disclosure is directed to devices and methods for simultaneously sensing irradiance with multiple photo sensors having different orientations, and determining direct and scattered components of the irradiance. One such device includes an aerial vehicle and an irradiance sensing device. The irradiance sensing device includes a base structure mounted to the aerial vehicle, and the base structure including a plurality of surfaces. A plurality of photo sensors are arranged on respective surfaces of the base structure, with each photo sensor having a different orientation.

Abstract: An example method includes applying ultrasound waves to a particular portion of a nervous tissue. The ultrasound waves are pulsed at a pulse repetition frequency. The method further includes detecting an electrical signal originating from at least the particular portion of the nervous tissue. The method further includes extracting a component of the electrical signal that oscillates at an oscillation frequency that is equal to (a) the pulse repetition frequency, (b) a subharmonic frequency of the pulse repetition frequency, or (c) a harmonic frequency of the pulse repetition frequency. The method further includes processing the extracted component to obtain one or more components that oscillate at respective frequencies that are unequal to the pulse repetition frequency. Systems and computer readable media related to the example method are disclosed herein as well.

Abstract: A novel musical instrument was created using electroencephalogram (EEG) motor imagery to control a synthesized piano, and is herein named the Encephalophone. Alpha-frequency (8-12 Hz) signal power, originating from either posterior dominant rhythm (PDR) in the occipital cortex or from mu rhythm in the motor cortex, was used to create a power scale which was then converted into a musical scale which could be manipulated by the individual. Subjects could then generate different notes of the scale by activation (event-related synchronization) or de-activation (event-related desynchronization) of the PDR or mu rhythms in occipital or motor cortex, respectively.
