A method, system and apparatus for preserving platform independence of a program while supporting native accelerators for performance critical program objects. The wireless device transmits first uplink signals in the secondary cell group employing a reference secondary cell in the secondary cell group as a timing reference. Each spark gap is connected to at least one winding which is inductively coupled to an associated winding connected to another spark gap so that, in use, a surge current flowing across a spark gap and through a winding connected to the spark gap induces a voltage in the associated inductively coupled winding connected to another spark gap. The seed meters are aligned in a non-horizontal configuration within each row unit, and one of the plurality of meters is operated at a time to plant a seed variety associated with the meter being operated.
