eCoupled is intelligent wireless power based on inductive coupling that allows for safe and efficient power transfer without wires.
Fulton Innovation is a technology licensing company. We are currently working with a growing number of designers and supply chain partners who support and manufacture components for our licensing partners.
Our parent company, Alticor, Inc., developed the Alticor eSpring™ water purification system, which utilizes a UV lamp to destroy any microbes present in the water. However, exposed electrical connectors for the UV lamp subjected it to corrosion and shortened lifecycle issues. To address these issues, our lead scientists developed a method to power the lamp wirelessly. eCoupled technology was born.
eCoupled operates on the principle of resonant magnetic induction. Magnetic induction means that electricity travels via magnetic fields instead of through a physical connection of conductive materials. Most electronics today use a power cord to transport power to the electronic circuits of the device. From there, a transformer uses magnetic induction to form an inductive link that safely transfers power between the internal circuits. eCoupled simply replaces the conductive power cord with another inductive link.
Just like a transformer, eCoupled uses coils to transmit energy. One coil in the eCoupled power supply generates a magnetic field at a frequency that will resonate with a second coil in a device equipped with eCoupled technology This resonant magnetic field causes electricity to be generated in a device with the secondary or receiving coil. One eCoupled power supply can charge or power a multitude of eCoupled compatible devices.
eCoupled technology overcomes the limitations of spatial rigidity, static loads and unacceptable power losses. It intelligently adapts to multiple loads – from milliwatts to kilowatts – and spatial configurations while maximizing energy transfer efficiencies, making eCoupled comparable to hardwired connections.
Intelligence - eCoupled uses a proprietary protocol to communicate with the devices it powers. It authorizes instantaneous identification of eCoupled-enabled devices and utilizes two-way feedback on the operation and status of the powered devices to monitor performance and power needs. By using tightly coupled fields and actively maintaining a high level of control, eCoupled is able to realize high efficiencies, reduce energy losses and insure the highest safety levels.
Parasitic Metal Detection - eCoupled immediately recognizes when any inappropriate device or object (non- eCoupled-enabled device) comes within range of a power source and automatically shuts down, maintaining one of the safest operating systems in the industry.
Environmentally Preferred - The intelligence of eCoupled makes it an environmentally preferred solution. Its intelligent communication protocols and design-friendly nature eliminates unnecessary cords and outdated power solutions and reduces energy being wasted through inefficient chargers. It also enables product designers and manufacturers the ability to reduce their carbon footprint and reduce landfill waste.
Alternative inductive coupling technologies utilize near-field magnetic induction. Unlike eCoupled, these technologies do not have an intelligent control system.
Conductive coupling requires physical contact through a conductive medium, such as a wire, resistor, or common terminal, such as a binding post or metallic bonding. eCoupled channels power electromagnetically without these constraints.
Broadcast/RF is the broadcast and transfer of electrical energy from point to point. Efficiency of such transfer is comparatively low.

Wireless power is a tremendous step forward in power supply/transfer for any industry or application. In addition to the convenience of eliminating incompatible power cords, it also enables our electronics to be more reliable, safe and energy-efficient.
eCoupled was originally developed by Fulton Innovation as a safe way to wirelessly power a 38W UV lamp in the Alticor eSpring™ Water Purifier. As the technology was adapted to solve the challenges within the eSpring system, its broad potential application to virtually any electronic power system was realized. Additional developments ensued; a strong IP portfolio was established; and Fulton Innovation began building relationships with manufacturing partners interested in a variety of benefits–from design freedom and differentiation to product safety, durability and reliability.
eCoupled has been on the market as a part of the Alticor eSpring Water Purifier for over 10 years. New eCoupled-enabled products include the Dell™ Latitude™ Z and the Energizer® Hard Case® Professional® LED Swivel Light. Additional products are slated to go to market in 2010.
eCoupled is a reality. The engineers behind eCoupled technology have been developing and perfecting the technology for over 12 years. eCoupled technology has been in the marketplace for over 10 years in Alticor’s eSpring™ Water Purifier with over 1.5 million systems sold in 40 countries and territories to date.
Presently, the technology is transferring over 1,400 watts at better than 98% efficiency. However, further scaling up is possible as applications evolve.
Yes, the primary power supply responds to the needs of the device and if a given device is fully charged, eCoupled technology recognizes this state and discontinues power delivery.
Consumers who have been frustrated by too many incompatible wires, cords and chargers can now look forward to the convenience of having a single universal solution for charging their devices wirelessly.
Manufacturers can benefit from increased product safety and performance, product differentiation, lower production costs and lower warranty costs. There’s also increasing consumer demand to eliminate incompatible power cords.
Flexible designs have been developed to incorporate standards that would allow the technology to be highly versatile over an extended period of time.
Yes. It currently draws a minimal current while searching for an eCoupled-enabled device. When a device is recognized, it will analyze and supply power as needed.
DC rail voltages have been scaled from 3VDC to 340VDC.
Currently, we are working with a growing number of supply chain partners who manufacture components for our licensing partners.
Before activating the primary coil embedded in the countertop, eCoupled technology uses a combination of sophisticated software algorithms and simple communications protocols to identify and profile each device. It then can recognize specific power requirements for that device and calculate the safest and most efficient method to deliver power wirelessly based upon coil geometry and location, battery charge profile (if present) and age of the device. From there, it monitors the power delivery and device condition and intelligently shuts down to conserve energy and eliminate waste.
eCoupled technology can be embedded into virtually any work surface with the exception of stainless steel or other metals. In the latter cases, we have methods for creating windows in surfaces to ensure power transfer occurs without interference.
Our engineers have developed proprietary solutions designed to handle everything from simple to very complex charging scenarios.
eCoupled technology provides a low cost method to implement wireless power. Ultimate pricing will depend on specific features and benefits and will be determined by the manufacturers who license eCoupled technology.
