US Patent 7728830 - Inverse GPS control of nanoparticle circuits

http://www.freepatentsonline.com/7728830.html

This patent teaches a new way of addressing nanoscale structures by using 3 wavefronts which are selectively delayed to intersect at a selected position. Claim 1 reads:

1. A method for addressing a plurality of nano-scaled structured elements embedded in an m-dimensional medium capable of wave-like propagation of signals, each of said plurality of nano-scaled, structured elements being reactive to a local state of the m-dimensional medium, said method comprising steps of:

a) sending, via a broadcast through said m-dimensional medium in a wave-like propagation from n+1 spatially localized transmitters, a plurality of control signals to the plurality of nano-scaled, structured elements arranged in an n-dimensional array within the m-dimensional medium, where a timing of initiation of said plurality of control signals is varied and each of said plurality of control signals reaches all of said plurality of nano-scaled, structured elements in said n-dimensional array; and

b) addressing at least one of the plurality of nano-scaled, structured elements, when said plurality of control signals propagating through said m-dimensional medium arrives at a common time at a location of said at least one of the plurality of nano-scaled, structured elements.
