Omnidirectional wireless charging pad tolerant of misalignment
This technology is a flat wireless charging pad that can power a device no matter how it is oriented or positioned on the surface. It uses multiple specially shaped coils arranged in different directions, each connected to its own independently controlled circuit. A smart controller selectively energizes individual coils with different power levels to create a magnetic field that reaches the receiving device regardless of its angle or placement. The result is a pad that eliminates the frustrating alignment problem common in today's wireless chargers.
What you could build
A drop-in wireless charging pad for consumer electronics, medical wearables, or industrial IoT sensors that delivers reliable power regardless of how the device is placed on the surface; likely buyers include consumer electronics OEMs, medical device manufacturers integrating charging into bedside or wearable systems, and industrial equipment makers powering sensors on flat surfaces.
Who in Virginia should care
Defense and federal contractors around Northern Virginia and the Pentagon corridor with programs requiring wireless power for embedded sensors or wearable soldier systems would find this relevant.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
