Wireless Mobile Charger Using RF Energy (Green Charger)

2020
This atmosphere is completely surrounded by radio frequency and microwave radiation, so a method is providing the power to charge a device or battery by the use of radio frequency. And we are representing a type of wireless charging system. So in this system, we can absorb the radio waves of certain range by the use of multiple receiver antennas, and ...

Comparability of mobility particle sizers and diffusion chargers

Journal of Aerosol Science, 2013
Abstract A large study on the comparability of various aerosol instruments was conducted. The study involved altogether 24 instruments, including eleven scanning, sequential and fast mobility particle sizers (five Grimm SMPS+C, three TSI SMPS and three FMPS) with different settings and differential mobility analyzers (DMAs), twelve instruments based ...

child Safety Mobile Charger

International Journal on Science and Technology
Mobile chargers are a common household accessory, but they present safety hazards when left plugged in. Exposed USB tips often retain a live 5 V, which may pose a risk to children. This project proposes a novel Child Safety Mobile Charger design in which the charger delivers 0 V at the USB-C tip unless a mobile phone is actually connected.

Efficient dispatch of mobile sensors in a WSN with wireless chargers

Pervasive and Mobile Computing, 2018
Abstract Hybrid wireless sensor networks (WSNs) contain static and mobile sensors to support various applications. Static sensors monitor environment to find where events occur. Mobile sensors (MSs) move to event locations (ELs) to do advanced analysis.

WRSNs: Toward an Efficient Scheduling for Mobile Chargers

IEEE Sensors Journal, 2020
Wireless Rechargeable Sensor Networks (WRSNs) are emerging systems to build data acquisition systems to monitor critical areas. It has better features than Wireless Sensor Networks (WSNs) since in WRSNs, sensors are rechargeable. Wireless Rechargeable Sensor Networks allow sensors with sensing ability to collect and supply data to the operation center (

Bidirectional resonant chargers for e-mobility

2023
This thesis investigates the development of efficient bidirectional chargers, an integral component for advancing e-mobility. Electric vehicles (EVs), energized by renewable sources, could mitigate the power grid instability by returning stored energy when renewables are less available. Battery voltage in EVs, however, can vary widely based on the EV's
