The rumored dual-screen surface of Microsoft might use this intelligent trick to improve wireless charging


Microsoft is rumored to have a dual-screen device in the works (potentially ready for airing as quickly as October), and has some bright ideas on how to make such a foldable job fine, with the recent prospective innovation being a multi-sided wireless electromagnetic coil.

A what, right now? Admittedly, that may sound fairly boring–and if you read the patent (spotted by Windows Latest), it will be boring to call with all his colleagues (tedium, tiredness and insipidity, perhaps tagging along with perplexity).

However, dig a little deeper into the patentese’s many heaped paragraphs and you’ll discover that Microsoft has a nifty-sounding trick up its sleeve that could assist NFC likes and wireless (inductive) charging perform better with a 2-in-1 dual-screen.

As noted in the patent by Microsoft, the design of a dual-screen laptop may pose difficulties in terms of the device’s many possible orientations (closed, laptop mode, tent, flat on the desk, completely folded back to use as a tablet).

Microsoft observes: “Multiple physical settings present a challenge when designing magnetic access to electromagnetic coils within a computer device, especially when metal casing, metal framing and other metal elements are present.”

The patent further states that the dual-screen device’s distinct orientations constitute an chance to use the likes of NFC functionality or inductive charging across multiple device sides, regardless of the setup it is used.

Sticking point

The sticking point is that the above-mentioned metal components of the chassis can “fatally diminish activities relying on inner electromagnetic coils” with features such as inductive charging use in some2-in-1 orientations.

The patent is therefore for an electromagnetic coil that provides multi-sided magnetic access in such a foldable device to overcome these problems. In other words, when it comes to the capacity to use something like inductive charging in whatever setup the hardware is presently in, the 2-in-1 would be provided a much higher amount of flexibility.

The described multi-sided electromagnetic coil “overlaps the first slot and the second slot along an orthogonal axis to the first part of the computer unit and the second part of the computer device [ first and second displays ].” Microsoft adds: “Control circuitry adjusts to compensate for distinct physical settings, and firmware switches the radio frequency setup.

As always with any patented technology, it is assumed by anyone that this will actually make the cut for a final product. But it definitely sounds like a smart concept to assist charging wirelessly on a dual-screen hardware item like the rumored Surface Centaurus from Microsoft.
