Wireless power system charges multiple consumer devices, remotely

On stage at the TechCrunch Disrupt event held in San Francisco, Ossia CEO, Hatem Zeine showcased how the technology could remotely power consumer devices by automatically delivering targeted energy to multiple devices from as far away as 10m, without requiring line of sight.

Operating in the WiFi frequency range and with a similar reach within the home, Cota could redefine power distribution, enabling users to charge or power a wide range of devices well beyond smartphones, to include remote controls, cameras, video game controllers, flashlights, smoke detectors and other battery-based applications.

Ossia’s patented smart antenna technology uses phased arrays of transmitters to transfer power without the use of inductive coils, ultrasonic waves, magnetic resonance, charging pads or mats. Capable of delivering 1W of power wirelessly on the receiver side, the Cota technology consists of two parts: a charger and a receiver. Although the exhibited prototypes where bulky, designed with off-the-shelf components, Zeine explained that with further integration, the whole power transmitting charger hub would not take more room than current WiFi home gateways. On the receiver side, Zeine expects to provide the Cota technology either as a chip and module, or as IP to be licensed to chip manufacturers for integration into cell phone designs.

The Cota-powered charger automatically locates Cota receivers built into devices or batteries, those deliver signals that are sent omnidirectionally. Once they hit the charger, these signals follow the same path back to the receiver, focusing energy at the exact location of the device, explained Zeine.

The wireless power system can be left open for any equipped device to recharge, or locked to specific devices (through initial pairing).

The technology is undergoing FCC approvals and the company expects the first Cota transmitters to reach market in 2015. Under license from Ossia, consumer electronics OEMs and ODMs could include Cota receivers in new products or build their own branded Cota transmitters.

Existing battery-powered devices can also be easily retrofitted with Cota receivers, even if they are already equipped with one of the three pad-based charging systems. Other companies such as construction and energy businesses are already exploring non-consumer electronics applications for Cota-based wireless power.
