At the recently concluded CES 2012, Toshiba paraded a fair number of new gadgets in addition to prototypes – and one of them is this waterproof tablet which can also be powered sans wires. It resided inside an aquarium most of the time on the showfloor, to show to the world just how its internal hardware is dammed up against any leaks. Toshiba came about this tablet by prototyping one based on its “Regza Tablet” that comes with a 10.1″ LCD display. According to Toshiba, “We prototyped it for displaying our technologies. We are not planning to commercialize it at this point.”
In order to send power wirelessly, Toshiba used the magnetic resonance method that has a relatively long range of transmission. With the distance between the prototyped tablet computer and a power-transmitting device measuring several centimeters, this allows the tablet to remain juiced while swimming with the proverbial sharks. There was no disclosure on the efficiency of the power transmission, although the efficiency level is not high.
