US Patent 7661229 Electrical conductivity in a suspended ceiling system

A ceiling system including a grid framework having a plurality of grid elements arranged in a substantially horizontal plane. A conductive material is embedded in one of the plurality of grid elements. The grid element in which the conductive material is embedded includes at least one slot such that portions of the conductive material are exposed. A tap is attached to the grid element so that it is in alignment with the slot, and, in turn, with the conductive material. The tap includes a housing, a conductor engaging means and a tap conductor. The conductor engaging means forms a connection with the conductive material embedded in the grid element and the tap conductor.
