Abstract: A micro electro-Mechanical System (MEMS) microphone includes a first back plate positioned on top of a first moving plate, wherein the first moving plate flexes in response to changes in air pressure caused by audio signals. The MEMS microphone also includes a valve comprising a valve moving plate, wherein a first end of the valve moving plate is fixedly attached to a MEMS die and the valve moving plate flexes in response to high sound pressure levels such that a second end of the valve moving plate enables airflow to prevent audio signal distortion.

Abstract: Methods, apparatus, systems and articles of manufacture to implement cooling fans with selectively activated vibration modes are disclosed. An example cooling fan assembly includes a motor and a fan coupled to a shaft of the motor. The motor is to rotate the shaft in a first direction to cause the fan to move air. The motor is to rotate the shaft in a second direction to cause vibration from an eccentric mass coupled to the shaft.

Abstract: Disclosed herein are systems and techniques to adapt an image to a gaze vector of a user or project content based on a distance between an appendage of a user and a at least a portion of a projected image. The system can include a projector to project an image and a camera to capture an image. The system can determine a gaze vector of a user and adapt the projected image based on the gaze vector. Additionally, the system can determine a distance between an appendage of the user and the projected image and project content based on the distance.

Abstract: An apparatus for audio beamforming with distance and environmental information is described herein. The apparatus includes a microphone or a plurality of microphones, a distance detector, a delay detector, and a processor. The distance detector is to determine a distance of an audio source from the apparatus. The delay is calculated based on the distance determined by the distance detector. The delay is determined for each of the microphones. Additionally, the processor is to perform audio beamforming of audio from the microphone array combined with a microphone specific delay applied to the audio signals from the microphones.

Abstract: An apparatus for providing low frequency expansion of speech includes a nonlinear function element, a band-pass filter element and a level control element. The non-linear function element is configured to receive a signal including at least two harmonic components and to produce a signal including at least one lower frequency harmonic component having a lower frequency than a highest frequency component of the at least two harmonic components responsive to the signal including at least two harmonic components. The band-pass filter element is in communication with the non-linear function element and configured to filter the signal including the at least one lower frequency harmonic component. The level control element is configured to apply a level control to alter the filtered signal based on a feature vector associated with an input speech signal.
