a memory;

a processing sequence stored in the memory;

a second control unit operably coupled to the memory and to the conductive traces, the second control unit operable to produce a second plurality of signals responsive to the first plurality of signals according to the processing sequence;

a housing enclosing the substrate and the second control unit; and

electronically and removably coupling the addressable assembly to the first control unit, the first control unit performing the function responsive to the second plurality of signals.

2. The method of claim 1, wherein the housing comprises a flowable material which encapsulates the substrate and the second control unit, and wherein the substrate and the flowable material entirely supports the plurality of connectors.
