Will need some thing to read it all. 

inductively powered LED design

This is a very interesting power transfer design. Using RLC circuit as channels to power up device through fraudulent controlled supply. Very clever concept. Nevertheless its inductively powered through pcb coil design. 👏

RLC band-pass filter design calculator (online)

This is a nice RLC Calculator tool.

I came across it through a YouTube video of inductively powered led circuit design.
