A Wideband, Synthetic Aperture Beamformer for Through-The-Wall Imaging

A coarray-based aperture synthesis scheme using subarrays and post-data acquisition beamforming is presented for through-the-wall wideband microwave imaging applications. Various effects of the presence of the wall, such as refraction, change in speed, and attenuation, are incorporated into the beamformer design. Simulation results verifying the proposed synthetic aperture technique for a TWI s...

Model Based Design approach for Implementation of PHEV Energy Management

Hardware implementation of the Plug-in hybrid electric vehicles (PHEVs) control strategy is an important stage of the development of the vehicle electric control unit (ECU). This paper introduces Model-Based Design (MBD) approach for implementation of PHEV energy management. Based on this approach, implementation of the control algorithm on an electronic hardware is performed using automatic co...

Wideband Piezoelectric Energy Harvester Tuned Through its Electronic Interface Circuit

This paper reports a novel technique enabling to tune the resonant frequency of linear inertial piezoelectric energy harvesters through the control strategy of the associated electronic interface circuit. When associated with piezoelectric devices exhibiting high electromechanical coupling, it is expected to enable the variation of the resonant frequency in large proportions.

Modelling the nonstationarity of speech in the maximum negentropy beamformer

State-of-the-art automatic speech recognition (ASR) systems can achieve very low word error rates (WERs) of below 5% on data recorded with headsets. However, in many situations such as ASR at meetings or in the car, far field microphones on the table, walls or devices such as laptops are preferable to microphones that have to be worn close to the user’s mouths. Unfortunately, the distance betwe...
