Abstract: The impairments due to in-phase and quadrature-phase imbalance at the transmitter and/or receiver, carrier frequency offset, and doubly selective channel (DSC) result in multiuser ...

Abstract: The rapid reduction of power transfer efficiency with misalignment is a matter of grave concern for compact high-power wireless power transfer (WPT) systems. The misalignment tolerance can ...

Porsche is set to become the first car maker to bring high-power, 11kW wireless car charging to the market, debuting the technology as an option on the new all-electric Cayenne, set to be revealed at ...

Moreover, if a quicker-charging system becomes available in the future, software alone won't be enough to realise that improved rate, said Porsche, so newer hardware would be required. Safety systems ...

The development was done on an Arduino Due. Tests have shown that the working range of several 433Mhz receiver modules strongly depend on the quality of the power supply. When the Arduino Due is ...

This cost-effective 433MHz wireless relay switch circuit allows remote relay control using an RF transmitter and receiver module. It is ideal for scenarios where wired connections are impractical or ...

this code is based on a default demo for the esp32-cam module, I extended the web interface with buttons to controll the rc-surveillance-car and the led, I also added modifications the C code. this is ...
