It is not difficult to see from the patent map published that this is a special design. Its modular capsule design will help to enhance the function of electronic touch pen.
Microsoft's design is based on the high cost and complex technology of electronic stylus manufactured in the current form. In addition, the design currently used is rather limited in space and the quality of the signal transmitted through it. For this reason, Microsoft seems to be turning its attention to external components or capsules.
The capsule is made of plastic material. It contains a cylindrical shell, an antenna at the top, an antenna on the outer surface of the shell, and an internal or external pressure sensor to assist the function of the stylus. The key part of the pressure sensing part is the axis, which runs along the longitudinal axis of the shell. Since the capsule itself will be a single entity, it will reduce the risk of failure of the stylus despite the active components.
In addition, because the antenna structure mentioned above is a "tilt" structure, it can send a higher quality signal to the digital instrument panel interacting with it. At the same time, "tilt" can also make the use of stylus more smoothly.
Modularization of capsules means that it will not be limited toSurfacePen, can be used in various styles and different designs of electronic touch pens. This approach will help manufacturers achieve cost-effective, simple manufacturing processes.
It is reported that Microsoft applied for this patent last year, but it is not clear whether it will eventually be available.
