Determining opening of portals through acoustic emissions

An apparatus comprising:

• a closure supply for a closure to retain a portal in a closed state while said closure is engaged with said portal, at least a portion of said closure being frangible so as to release said portal from said closed state and produce an acoustic emission upon a yielding of said at least one portion;
• a base data input;
• an encoder in communication with said base data input so as to receive base data therefrom and encode said base data to produce encoded data therefrom, said encoded data comprising a yield sequential nonuniformity of yield strength in said closure;
• and
• a modifier in communication with said encoder so as to receive said encoded data therefrom and modify said closure to exhibit said yield sequential nonuniformity such that upon said yielding of said closure said acoustic emission exhibits an acoustic sequential nonuniformity with said encoded data incorporated therein.

An apparatus comprising:

• a base data input;
• an encoder in communication with said base data input so as to receive base data therefrom and encode said base data to produce encoded data therefrom, said encoded data comprising a yield sequential nonuniformity of yield strength in a closure external to said apparatus to engage a portal to exhibit said yield sequential nonuniformity;
• and
• a modifier in communication with said encoder so as to receive said encoded data therefrom and modify said closure.

A method, comprising:

• establishing a closure to retain a portal in a closed state while said closure is engaged with said portal, at least one portion of said closure being frangible so as to release said portal from said closed state upon a yielding of said at least one portion and to produce an acoustic emission upon said yielding;
• encoding base data to produce encoded data therefrom, said encoded data comprising a yield sequential nonuniformity of yield strength in said closure;
• and
• modifying said closure to exhibit said yield sequential nonuniformity, such that said yield sequential nonuniformity produces an acoustic sequential nonuniformity of said acoustic emission upon said yielding of said at least one portion.

An apparatus, comprising:

• means for establishing a closure to retain a portal in a closed state while said closure is engaged with said portal, at least one portion of said closure being frangible so as to release said portal from said closed state upon a yielding of said at least one portion and produce an acoustic emission upon said yielding;
• means for encoding base data to produce encoded data therefrom, said encoded data comprising a yield sequential nonuniformity of yield strength in said closure;
