A cap with tinfoil as radiation protection layers comprises a cap body, a top radiation protection composite layer and a side radiation protection composite layer. The top radiation protection composite layer and the side radiation protection composite layer are the same in structure and are both composed of a tinfoil layer and a flexible connecting layer, the top radiation protection composite layer is connected to the top of the inner wall of the cap body, and the side radiation protection composite layer is connected to the side portion of the inner wall of the cap body. The tinfoil layers coat one faces of the corresponding flexible connecting layers, and the other faces of the flexible connecting layers are connected to the inner wall of the cap body through adhesive patches. The adhesive patches are hook-and-loop fasteners, and the flexible connecting layers are cloth. The tinfoil is used as the radiation protection layers, the cap has the advantages of being simple in manufacturing process, convenient to manufacture, low in cost, uniform in thickness and convenient to carry, and well overcomes the defect that an existing radiation protection cap is uncomfortable in wear, the top radiation protection composite layer and the side radiation protection composite layer can be flexibly taken down, and the function of an ordinary cap and the function of the radiation protection cap are achieved.
Does this mean the AFDB is now subject to a patent? No. This patent is focused on attaching a removable inner foil deflector layer to an outer cap using velcro, so AFDBs per se are not covered. However, this patent could be used to claim the exclusive right to attach a hat to an AFDB, a common form of camouflage among the beanied.
Past actions by patent trolls have shown that mere end users of a product supposedly covered by a patent can find themselves facing demands for license fees (see MPHJ vs. anyone using a scanner to send emails). Even if these demands are later determined to be bogus (as the MPHJ patent abuses eventually were), they can still be a means of expensive harassment.
So, could this patent be a ploy by the forces of mind control to keep paranoids from hiding their beanies under a hat for fear of a lawsuit? While it's possible some legalistic faction of said forces might try such a tactic, it seems pointless.
If you are discovered to have been violating this patent, that means you have also been discovered to be an active paranoid seeking to avoid psychotronic mind-control. Instead of finding yourself in some East Texas court pleading to avoid paying license and lawyer fees, you're more likely to be abducted by a mind-control compliance van (which look like this, btw.)
Paranoids are advised to ignore any legal threats related to this patent and continue camouflaging their beanies. If you receive a cease and desist, assume your cover as an orthonormal is blown and go to ground.
