Method and apparatus for processing signals of a spherical microphone array on a rigid sphere used for generating an ambisonics representation of the sound field
Spherical microphone arrays capture a three-dimensional sound field (P(Ωc, t)) for generating an Ambisonics representation (Anm(t)), where the pressure distribution on the surface of the sphere is sampled by the capsules of the array.

In-the-ear automatic-noise-reduction devices, assemblies, components, and methods
Automatic noise-reduction (ANR) headsets include circuitry that cancels or suppress undesired noises. Recent years have seen the emergence of in-the-ear (ITE) earphones that incorporate ANR technology; however, designing them to function well usually entails many design tradeoffs, such as using larger ear nozzles that are uncomfortable to obtain desired noise reduction or that require added structures to hold the earphones to a user ear. To avoid these tradeoffs, the present inventors devised, among other things, an exemplary ITE ANR earphone that places its error measurement microphone in the ear nozzle that connects the driver front acoustic volume to a user ear canal. This placement allows use of a narrower more comfortable ear nozzle without compromising noise reduction and without requiring added holding structures. Moreover, the narrower ear nozzle also lowers the likelihood that the ANR circuitry will become unstable and produce undesirable noise. |

Stress induction in 3D device channel using elastic relaxation of high stress material
A method for inducing stress in a device channel includes forming a stress adjustment layer on a substrate, the stress adjustment layer including an as deposited stress due to crystal lattice differences with the substrate. A device channel layer is formed on the stress adjustment layer. Cuts are etched through the device channel layer and the stress adjustment layer to release the stress adjustment layer to induce stress in the device channel layer. Source/drain regions are formed adjacent to the device channel layer. |
