Based on my review of the document, there are **no proposals** explicitly marked as such in this contribution. 

The document is an evaluation data submission for Device 3 in the DaCAS-2 work item. It contains technical specifications, recording parameters, and database information, but does not include any sections explicitly labeled as "Proposal", "Proposal X:", "Proposal X.", etc.

The Conclusion section (Section 3) mentions that "The proposed draft database is submitted for the group's review" but this is a descriptive statement rather than a formally marked proposal.
