Please see and read such url ::::> http://tech2.in.com/features/general/wireless-charging-will-it-become-an-industry-standard/756752
Looking for Potential and knowledgeable engineer in developing a wireless device of :
a) USB wireless charger (Transmitter) with sample of usage (wireless charging within car, house living hall)
b) distance issue is a must to take note. >>> DO NOT require distance of 10 mm or cm .. need longer / further distance of the charging lenght (up to 2 or 3 meters) thus coil / field should be appropriate to handle such situation.
c) receiver should be able to cope for android phone (micro usb) and iphone (depends on the version if possible)
d) once fully charged, the energy transfer should be stop (between transmitter and receiver)
e) test cases on efficiency of the charging on the possibility of energy lost / interference.
If you have experience or knowledge in this project, you may bid for this
Looking for budget at $1000 BUT will not recognize any sense of escrow payment. Payment works in sense of, once you are able to provide me with the information and show that you are the suitable candidate, will select you as the winner. Prototype is built and working, i will transfer directly half of the charges to you and u will post me the prototype for further testing. Demo documentation and test case should be included as well.
After tested successfully or with some required changes, will then proceed with the final balance transfer and then you will provide me with the full documentation.
If you have ready and working device / prototype, this should be easier... On the budget, we can discuss up to $1300 (this apply for other type of bidding as well if the proposal is good and realistic)
