Design and kinematics of 4- DoF multi-purpose wearable mechanical arm (MUWA) support for enhanced operation stability
(IEEE, 2019)
A low-cost motor-less simple wearable mechanical arm support unit is presented as a viable alternative to todays assistive exoskeleton support units. By limiting the functionality of the device to stabilization rather than ...
Adaptive 6.78-MHz ISM band wireless charging for small form factor receivers
(IEEE, 2017)
This paper presents a low cost wireless power transfer system tailored particularly for size limited insulation sealed wearable devices. The 5-V USB input system features a crystal oscillator as reference signal source, a ...
An improved speed controller for PMSM drive with unbalanced load using load torque observer
(IEEE, 2019)
In order to overcome disturbance effects as load torque variations in Permanent Magnet Synchronous Motor (PMSM) of washing machines, an improved controller with feed forward compensation is presented in this paper. A few ...
The design of a high gain dual-polarized quad-ridged circular horn antenna for wideband EMC test applications
(The Applied Computational Electromagnetics Society, 2018-09)
This paper presents the design of a high gain broadband quadruple-ridged circular horn antenna for Electromagnetic Compatibility (EMC) testing. The proposed antenna contains a wideband feed structure as a transition between ...
Design and simulation of microfluidic device for metabolite screening and quantitative monitoring of drug uptake in cancer cells
(Sciendo, 2018)
Although liquid-liquid extraction methods are currently being applied in many areas such as analytical chemistry, biochemical engineering, biochemistry, and biological applications, accessibility and usability of microfluidics ...
Dopamine detection using mercaptopropionic acid and cysteamine for electrodes surface modification
(Sciendo, 2018)
Gold electrodes are often not suitable for dopamine measurements as dopamine creates a non-conducting polymer layer on the surface of the electrodes, which leads to increased amount of electrode passivity with the gradual ...
A sub-sampling pulse-resonance OOK modulated digital ultrasound communication system for biomedical IoT
(Elsevier, 2019-11-01)
A pulse-resonance On-Off keying ultrasound communication microsystem is presented. It is a viable alternative to today's widely used RF technologies in order to avoid the associated health risks for a specific group of ...
A robust voltage control method for universal EV battery charger LLC resonant converters
(IEEE, 2019)
In this study, a novel control method for LLC resonant converter with wide output voltage range and constant switching frequency is proposed targeting wide range of Electric Vehicle (EV) battery charger standards. In ...
An experimental study of a bluetooth communication system for robot motion control
(IEEE, 2019)
This paper presents a method that aims to reduce the complex cabling problem in robotics applications, so as to prevent difficulties in troubleshooting processes and failures in case of cable breaks. Examples in the ...
16-elements helical antenna system integration with a solar cell powered IoT collector
(IEEE, 2019)
An 868MHz-915MHz 16-elements helical wire antenna array design with a solar-cell integration is presented. Each element is designed to be omni-directional with the corresponding tuning stubs and ground substrate. This is ...
