Certainly few things can surprise us at this point with the issue of patents. Apple is a specialist in patenting everything that it thinks it can use in the future or simply that it could give you money in the long run if someone wants use this patented technology.
In this case we are dealing with a patent directly related to the Apple Watch and more than to the watch itself, with its straps. The new Apple patent registered in the United States Patent and Trademark Office, shows us the "automatic adjustment for portable electronic devices" that is, self-adjusting straps.
The strap itself adds a series of sensors that determine the perfect fit of the watch to the wrist, allowing automatic adjustment when it is time to wear the watch. Obviously the strap adds the option to loosen the strap at any time and the possibility of tightening or loosening it manually. To carry out this process the patent talks about valves, deployable parts and gas bags to perform all the functions detailed.
In this case, the straps that Apple raises would undoubtedly be somewhat thicker than the current ones, there is no talk about sizes and neither about the possibility of using this patent in the near future. It seems clear that this accessory market for the Apple Watch could be expanded in terms of gadgets, straps or the like in the future, but we must not think that this will be a reality. We have already seen many other patents obtained by Apple that were left in that, registered patents.
