    Abstract: Techniques described herein generally include methods and systems related to a MEMS-based audio speaker system configured for generating an audio signal. The speaker system includes one or more apertures in the speaker system positioned to receive the ultrasonic carrier signal and one or more movable and over-sized obstruction elements that are configured to modulate the ultrasonic carrier signal and thereby generate an audio signal. Because the movable obstruction elements are configured to overlap one or more edges of the apertures when in the closed position, modulation depth of the generated audio signal can be substantially improved or otherwise varied.

    Abstract: Techniques described herein generally include methods and systems related to a MEMS-based audio speaker system configured with multiple speaker devices to generate an audio signal that is substantially without a high-band ultrasonic signal. Energy may be transferred to a low frequency sideband of the audio signal output and substantially eliminated from the high frequency sideband of the audio signal by passing an acoustic carrier signal through two different modulators. One modulator may implement a first modulation function on the acoustic carrier signal to generate a first audio signal, where the first modulation function may be based on a target acoustic output signal for the MEMS-based audio speaker system. The second modulator may implement a second modulation function on the acoustic carrier signal to generate a second audio signal, where the second audio signal may be the Hilbert transform of the first audio signal.

    Abstract: Techniques described herein generally relate to a refractometer. Using electromagnetic energy, the refractometer can accurately measure refractive index of a liquid without bulky precision optics. By empirically determining a relationship between the refractive index of a liquid sample and a measured reflected power from a resonant structure when in contact with the liquid sample, the refractive index of a liquid can be determined by measuring this reflected power. Furthermore, using multiple light sources of different frequencies, the refractive index of the liquid sample can be determined over a very broad spectral range, for example from ultra-violet to far infrared.
