Omnidirectional WPT and data communication for electric air vehicles: feasibility study

This paper investigates the feasibility of using the three dimensional omnidirectional inductive channel for power transfer and as a power line communication PLC for ground-based vehicle, electric air vehicle or space applications, the simulation results is performed by the advanced design system software using lumped equivalent circuit model. The power transfer efficiency determined based on multiport scattering (S)-parameters numerical simulation results while the theoretical channel capacity is calculated based on Matlab software as a function of the coupling coefficient considering an additive white Gaussian noise . Furthermore, the magnetic field distribution is evaluated as function of the misalignment angle θ between the receiver and the three orthogonal transmitters coils

Characterization of a Two-Coil Channel Considering Misalignment Scenarios

Publisher Copyright: © 2022 by the authors. Licensee MDPI, Basel, Switzerland.WPT system performances highly depend on the misalignment scenarios of the transmitter or the receiver coil. In this contribution, the authors analyze the effect of the misalignment influencing factors of the integrated WPT-PLC system receiving coil on the system performances. The simulations and experimental analysis are based on power efficiency and channel capacity metrics. The simulations are performed using finite element calculations in COMSOL Multiphysics and Advanced Design System (ADS) from Keysight technology. By analyzing the results, maximum transferred power is reached under resonance conditions. For instance, the calculated efficiencies versus the misalignment cases of the WPT-PLC system varies (η = 86% to 60%) when d = [3 cm to 7 cm], s = [3 cm to 9 cm], and for a tilt angle θ ≤ 20 deg, while the optimal data rate C(bps) is achieved while appealing different data access points and under reasonable SNR value.publishersversionpublishe

Google Assistant’s Interpreter Mode: is it really an interpreter?

This study investigates whether Google’s Interpreter Mode can replace human interpreters within the context of a journalistic interview. In the first part, we explored the theoretical aspects of our work by discussing speech-to-speech machine translation and its components as well as its place within the world of journalism. We then presented Voice Assistant and Google’s Interpreter Mode. The second part of this work discusses the experiment that we conducted by simulating three journalistic interviews which allowed us to evaluate Interpreter Mode. Interview participants evaluated the usability of the system as well as the fluency and adequacy of the translations it produced. We, on the other hand, looked closer at the number of successful interactions between the system and the users, as well as other metrics. Our result-analysis showed that Interpreter Mode is not capable of replacing human interpreters in the context of a journalistic interview

Wireless Power Transfer and Data Communication Cognitive Radio through Two-coil Inductive Channel

This paper investigates two-coil inductive channel for an efficient Wireless Power Transfer (WPT), while intelligently enabling high-data rate communication. The analysis is based on the power efficiency and channel capacity performance, which are determined based on the multiport scattering (S)-parameters numerical simulation results, using a lumped equivalent circuit model. Different access points and configuration scenarios, along with the decoupling filters design consideration of power and data links, were compared in order to cognitively share the two-coil inductive channel, for handling both high-power signal and low- power modulated high-frequency data signal. The performance of the transmission and isolation between the power and data link is evaluated. The theoretical channel capacity of the proposed two- coil circuit is calculated, as a function of the coupling coefficient k12, as well as in the presence of an additive white Gaussian noise and signal to noise ratio. This paper adds to the intelligence and cognition of the radio, to efficiently use the limited available spectrum for broadband communications, in addition to power transmission, simultaneously
