Digital media frames with memorial content immortalize dead memory highly technologically, artistically, and for a long time. Multimedia digital frames placed in water-proof metal cases adopt high transparent tempered glass and anti-thieves locking system. Shells fixed with special glue on the monuments, tombstones, steles at the cemeteries. Automatically with the appearance of visitor in prescribed radius, or using WI-FI (wireless) controller content placed in media frame: photos, texts or video begins playing. Supply power carried in different ways: as wired (AC adapter) if power source exist, or independently (depending cost of media frame): Powerful replaceable battery, which customer is easily inserted by opening metal case equipped with personal electronic (or mechanical) lock and key; Powerful battery TOGETHER with a solar battery, mounted in the housing media frame; Set of modern solar cells collecting light from the environment, making other energy sources unnecessarily

Данное изображение представляет собой рисунок инопланетянина Пафи, держащего в правой руке существо, напоминающее зайца, с перебинтованной лапой. Инопланетянин имеет большие, выразительные глаза цвета радуги, а также покрыт оранжево-желтой шерстью. Отдельно выделено розовое брюшко существа.

It was considered a model of inhomogeneous vector field within an associative algebra (Clifford algebra) on generalized coordinates. It is shown the derivation of the equations: two systems of Maxwell equations as a single equation, conservation laws 4-current and Einstein field equations. The geometrical interpretation for 4- current was given. Also the nontrivial "law of conservation of 4-dimensional curl of current" was received.
