Abstract: An audio signal processing method implemented by an audio system with an audio sensor and a speaker unit includes: measuring, by the audio sensor, acoustic signals reaching the audio sensor, producing a sensor audio signal; retrieving a speaker audio signal corresponding to a speaker acoustic signal from the speaker unit while measuring the acoustic signals reaching the audio sensor to produce the sensor audio signal; converting the speaker and sensor audio signals to speaker and sensor audio spectra; estimating, based on the speaker audio spectrum, an echo audio spectrum of an echo audio signal caused by the speaker acoustic signal in the sensor audio signal; computing, based on the echo audio spectrum and the sensor audio spectrum, echo suppression gains to be applied to the sensor audio spectrum, by using a MMSE-LSA estimator; and applying the echo suppression gains to the sensor audio spectrum.

Abstract: Different approaches that aim to extend scan range of phased array antennas by means of altering surface waves and/or altering the coupling are disclosed. One approach includes providing a phased array antenna where a surface of a substrate that houses antenna elements of the array includes openings such as trenches or grooves. Such openings in the surface effectively reduce the dielectric constant of the substrate, are easy to manufacture, and may reduce or eliminate the need to use exotic and expensive low-k dielectric materials. Another approach includes providing a phased array antenna where antenna elements are disposed over a substrate in the form of surface mount (SMT) components that are reduced in size/footprint. Using SMT antenna elements with a reduced size allows achieving the same gain while spacing antenna elements farther apart with gaps in between the antenna elements, thus also reducing the overall dielectric constant of the substrate.

Abstract: Micro-scale passive devices, such as transformers and capacitors, having an insulator layer with insulative particles and/or conductive or nonlinear conductive particles disposed therein. The insulative particles disposed in the insulator layer can increase a breakdown electric field of the device, and the conductive or nonlinear conductive particles disposed in the insulator layer can reduce a maximum electric field of the device. Increasing the breakdown electric field of the device and/or reducing the maximum electric field of the device can increase the lifespan of a micro-scale passive device, and/or may allow the device to operate at a higher threshold electric field without breakdown of the device.

Abstract: The present disclosure relates to an audio signal processing method implemented by an audio system which includes at least an internal sensor, wherein the audio signal processing method includes: measuring, by the internal sensor, a voice signal emitted by the user which propagates via bone-conduction to the internal sensor, thereby producing a bone-conducted audio signal; processing the bone-conducted audio signal by a machine learning model, wherein the machine learning model is previously trained to produce a predicted air-conducted audio signal which corresponds to a prediction of an audio signal that would be produced by measuring the same voice signal propagating via air-conduction to a microphone, by increasing a spectral bandwidth of the bone-conducted audio signal and/or by reshaping a spectrum of the bone-conducted audio signal; and producing an internal signal for the internal sensor based on the predicted air-conducted audio signal.

Abstract: A minimally invasive surgical instrument using 3-axis magnetic positioning, system and methods thereof. This invention describes two key ideas that enable the development of a magnetic position system based on integrated anisotropic magnetoresistive (AMR) magnetic field sensors. This achieves the resolution, power and area targets necessary to integrate 3 axes anisotropic magnetoresistance (AMR) sensors along with the Analog Front End integrated circuit (IC) in a 4 mm by 350 um integrated solution for catheter applications. The stringent area and power dissipation requirements are met by development through both system level solutions for higher field strengths and a minimally necessary Analog Front End (AFE) to meet the 1 mm rms resolution requirement in the power dissipation and area budget.
