A tag team consisting of tech company Fulton Innovation and office furniture maker Herman Miller Inc. could allow mobile phones, PDAs, laptops, portable music players, Bluetooth headsets and so on, to be one day wirelessly charged by your office desk. A technology called eCoupled needs to be integrated into an office desk in order to charge a device without power bricks, cables or even the original chargers. Wireless charging is possible thanks to Fulton's use of magnetic fields.
Fulton's device would be the only device that would require a direct electrical connection. The technology is already being used to charge Philips Sonicare tooth brushes while charging of Motorola phones and Apple iPods is in the works. Analysts find the technology intriguing and believe it could save companies and users a ton of money in the future. "Those things are 30 bucks each and if you have 50 people in your office the cost really adds up," said Jim Lynch, director of the Association of Professional Office Managers.
According to Fulton's description of eCoupled: eCoupled technology includes an inductive coupled power circuit that dynamically seeks resonance, allowing the primary circuit to adapt its operation to match the characteristics of the load. The power supply circuit automatically optimizes efficiency by seeking resonance at ultra-high frequencies between the primary and secondary coils for any given load.
