No patents were announced.  No opens were raised.

Michael Mirmak invited Brad Brim to summarize his e-mail proposal on sparse
matrices.  Brad suggested that the participants essentially agreed on
the approach but had yet to resolve some small issues.  These include
whether a label should be used to identify the sparse mapping terms and,
if so, whether it would be limited to being an integer or could also
be a string.

Walter Katz commented that he agreed with Bob Ross's proposal (distributed
via e-mail) to use ordinal organization based on column or column number.
He added that the number of columns provided for any frequency is equal
to the number of framises.

Bob agreed to create picture/presentation that shows the mapping between
The sparse and the full matrix.  He noted that any documentation must
distinguish between non-symmetrical (e.g, tapered) matrices and non-reciprocal
matrices (connectors, cables, etc. are reciprocal by definition).

Walter suggested that an ordinal label be required.  Bob added that the
information section will contain the mapping between label text and the
ordinal framis number.

Walter suggested that can only Si,j pairs may only be repeated within
the same framis.  A reciprocal matrix Sj,i in the same framis should not
be a problem.

Michael will turn the additional comments from the e-mails and meetings into
a single change proposal.
