========================================================================
No patents were announced.   Michael raised an open regarding meetings
after next week, due to his own travel.  The schedule will be settled
at the next meeting.

Tao Su summarized his proposals regarding specifying voltage and current
relationships in addition to row- and column-arranged data sets.  Without
establishing these relationship, no complete definition for mixed-mode and
single-ended matrices is possible.  One new line per port relationship
would establish the voltages, currents and reference impedances used for
each relationship.  

Bob noted that requiring single-ended impedances and parameters would
still be possible under this system.  Reference nodes for each port 
would still need definition.

Tao will provide examples of his proposal for discussion next time.

========================================================================

Team Objectives:
1) complete ICM-IBIS linking BIRD and any associated changes to the 
   ICM specification
2) update the ICM specification, if needed, to clarify the mapping of 
   ICM nodes to S-parameter ports
3) complete a specification for "Touchstone Plus" or similar 
   industry-standard definition for Touchstone-like files, to include 
   complex impedance references, removal of limits on the maximum number
   of ports and per-port impedance references
