Low-cost thin-film passive RFID circuits and detector system
(Cambridge University Press, 2020-06)
This paper discusses the design of chip-less RFID tags of a standard pocket size of 69 mm by 156 mm. These tags are based on lumped elements of copper metal traces constructed on a thin polyamide flexible substrate. Moreover, ...
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 ...
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 ...
Resonance-filtering combo system for continuous wireless charging range coverage
(Cambridge University Press, 2020-09)
Distribution of wireless power charging field uniformly on a large area pad is critical for power receivers, particularly for wearable devices, wherein small form factor coils are involved. Since the receiver coil size is ...
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 ...
Semi- and fully-random access LUTs for smooth functions
(Springer, 2020)
Look-Up Table (LUT) implementation of complicated functions often offers lower latency compared to algebraic implementations at the expense of significant area penalty. If the function is smooth, MultiPartite table method ...
Experimental evaluation of a software defined visible light communication system
(IEEE, 2020)
Visible light communication (VLC) allows the dual use of light-emitting diodes (LEDs) for illumination and communication purposes. With its large bandwidth and immunity to electromagnetic interference, VLC can be used as ...
A stochastic value estimation tool for electric vehicle charging points
(Elsevier, 2021-07-15)
A stochastic value estimation tool serves as a planning tool with embedded modules for electrical and financial valuation of electric vehicle charging points. The tool is developed in stochastic nature for selected service ...
