Engineering answers, with the paper attached.
arXiv, USPTO and EPO patents and CERN open data in one API, for teams building AI for hardware and physical R&D.
The problem
Where engineering time goes.
Prior art hides in patents.
Much of what has been tried in hardware is only written down in patent filings, never in a paper.
Figures depend on conditions.
A thermal resistance or a coherence time means little without the device stack, temperature and method behind it.
The field moves in preprints.
Physics and engineering results reach arXiv long before they reach a journal.
Design research
Prior work, before the design review.
Ask how an approach has been tried and get the papers behind it, with dates and links, from one call.
