Abstract: Dr. Mac Truong's invention described in U.S. Pat. No. 5,799,488 dated Sep. 1, 1998 creates what he calls “Trees of Life”, or “Forest of Life”, i.e. trees grown from ashes of identified individual human beings, representing deceased people's embodiment after their death. In this invention the same inventor invents what he calls “Tree of Life Precursor” or “Advanced Tree of Life” or “Trees of Life of living people.” As such everybody who desires it may have a Tree of Life Precursor created and growing while he/she is still alive, and once he/she is dead, his/her family would not have to undergo any pain, inconvenience, complication or embarrassment of burial or other methods of funerals. They only have to deposit the ashes of their deceased loved one at the roots his/her “Tree of Life Precursor” or “Advanced Tree of Life”, which becomes the conventional “Tree of Life” being created pursuant to the method described in Dr. Mac Truong's U.S. Pat. No. 5,799,488.

Abstract: Those hijackers seeking to commit suicide by crashing a plane into a selected target are frustrated because the selected targets, such as a nuclear plant or a governmental building, are provided with Repulsion Transmitters emanating an encrypted signal throughout a relatively small protective zonez. Planes are provided with receptors detecting such repulsion signals, together with discriminatory analyzers distinguishing between safe tangential travel through such zone and dangerous radial or spiral approach toward such target Both ground crew and the robotic controls within the plane are alerted and when appropriate, activated to re-route the plane to avoid the collision planned by the hijackers.

Abstract: When a tree has special value, there are hazards that vandals will damage the tree, thereby running the risk of killing it. Cemeteries have long been poular with vandals, resulting in damage to many tombstones. The Memorial Grove described in Truong U.S. Pat. No. 5,799,488 resembles a cemetery in that there are long periods when the visitor density is low, thus increasing the probability of vandalism. An installation is provided in which a plurality of potted trees are normally maintained at a level lower than the spectator's level, there being a system so that a potted tree can be placed on a platform and lifted to a level making it suitable for the spectator to see but not touch. Such an installation can be predominantly outdoors, or can utilize a building permitting the potted tree to be exposed to the weather much of the time, while having a shiftable skylight usually maintained in its parked position but shiftable to cover the opening in the roof to thus protect the tree during adverse weather.

Abstract: A Memorial Grove is designed so that the walkways for spectators are spaced from the displayed trees, thereby minimizing the amount of vandalism attributable to spectators touching the trees. Substantially each of the trees is a dwarf tree, whereby the capital investment per tree is less than when employing trees of conventional size. A shiftable skylight protects the displayed trees from adverse weather without encountering the problems inherent in growing trees in a building interior having trivial exposure to the weather.

Abstract: An area scheduled for visiting by persons desiring to pay homage to a deceased human features a group of identified trees, each planted to be an embodiment of the ongoing life of a particular human who has died. A precursor of a tree, such as a seed or a seedling, is planted in a nutrient composition featuring the dirt-like material, preferably ashes, derived from the remains of said deceased human. The Treelets are nurtured during a period of significant growth in the said nutrient composition.
