Unimatrix

A unimatrix was a type of subdivision used by the Borg Collective. Unimatrix was also a type of shielding technology used by Starfleet. 

The subdivision was used to designate groups of Borg drones and regions of space. A drone division could be further broken down into a trimatrix. The unimatrices of space were broken down into grids. The space inside a grid could be further specified as octants. The Borg also use the designation matrix of regions of space. 

In 2375, Lieutenant Commander Tuvok of the USS Voyager designed unimatrix shielding used in the multispatial probe and the shuttlecraft.
