Abstract: The present is directed to a “virtually indestructible” mailbox which has a dome shaped end directed to destructive snow plow road work, anti-destructive armour shape is to propel any incoming impact forces and to be absorbed into the circular body by transferring impact loads into the tubular armour bullet-like shape. The mailbox as a vault, having a circular plan and in the form of a spherical dome, so constructed as to exert an equal impact load into armour shape shell body.

Abstract: pe1A dynamic keyboard includes a plurality of keys, each with an associated symbol, which are dynamically redefinable to provide access to higher level keyboards. Based on sequenced symbols of keys sequentially activated, certain dynamic categories and subcategories can be accessed and keys corresponding thereto dynamically redefined. Dynamically redefined keys can include embellished symbols and/or newly displayed symbols. These dynamically redefined keys can then provide the user with the ability to easily access both core and fringe vocabulary words in a speech synthesis system.
