Illinois Patent of the Month – September 2023

NuCurrent, Inc. has been making a name for themselves for 14 years, transforming electronic devices and how we interact with them. With a foundation in innovation, the company has not never stopped investing in research and development. Recently, the company has patented a signal damping system to improve communications fidelity.

At its core, this innovation addresses the challenge of combining high-frequency wireless power transfer with reliable data communication, all while maintaining efficiency and fidelity. Traditional systems often use separate antennas and circuitry for power and data, resulting in inefficiencies, interference, and increased costs.

NuCurrent’s approach tackles these issues head-on by introducing a damping circuit into the wireless power transmission system. This circuit, armed with damping transistors, diodes, capacitors, and resistors, selectively dampens the AC wireless signals during data transmission. This means that while wireless power is being transferred, data can also be transmitted efficiently within the same channel.

One of the remarkable aspects of NuCurrent’s invention is its ability to adapt to the state of the wireless data signals. When data signals are “low,” the damping circuit is activated, efficiently accommodating data transfer. Conversely, when data signals are “high,” the damping circuit deactivates, allowing for seamless power transfer.

Moreover, the system is designed to consider the quality factor (QRx) of the wireless receiver system, ensuring optimal performance tailored to specific scenarios. This level of adaptability and optimization showcases the sophistication of this wireless power transmission system.

To further enhance efficiency, NuCurrent’s innovation instructs the power conditioning system to adjust the input voltage (VPA) based on the activation status of the damping circuit. This feature compensates for power loss during damping, ensuring that the overall power transfer remains efficient.
