Are there any parts out there that provide for non-contact power and communications for electronic devices?
I'm working on a product that'll consume low power (around 200mW), but that would benefit greatly if it could be mated to a computer via some super-low-range non-contact power source. The model of what I'm thinking of is an inductive loop that transmits using some means (FSK?) and receives by sensing variations in the load of the loop.
There's a standard out there (Qi) that covers the power part, but I'm not finding anything that covers the power and talking back and forth.
