Abstract: Systems and methods to provide acoustic monitoring are disclosed, comprising receiving a first acoustic signal and providing a first analog signal output representative of the received first acoustic signal using a first sensor, determining at least one of a continuous noise level of the first analog signal output of the first sensor or a peak level of impulse noise of the first analog signal output of the first sensor using analog signal processing circuitry, and sampling, using digital signal processing circuitry, at least one of the determined continuous noise level of the first analog signal output or the peak level of impulse noise of the first analog signal output from the analog signal processing circuitry to provide data privacy of the first analog signal output.

Abstract: Systems and methods to provide vocal acoustic attenuation for an acoustic sensor are disclosed, comprising attenuating an acoustic signal using an attenuation material covering at least a portion of a first surface of the acoustic sensor.

Abstract: An apparatus for characterization of one or more light sources, has an image sensor array that defines an image plane having an imaging area. An aperture spaced apart from the image plane defines the field of view that includes, for each of the one or more light sources, a corresponding incident light path that lies along a central ray beginning at the corresponding light source, extending through a center of the aperture, and terminating at the image plane. A diffraction grating forms, on the image sensor array, for each corresponding light source, a light pattern having at least a zeroth diffraction order and a first diffraction order, wherein the zeroth diffraction order is a geometrical projection of the aperture along the central ray. A control logic processor identifies a wavelength range and angular direction within the field of view for at least one of the light sources.
