Early in my career, I knew a woman who had a medical condition that confined her to an electric wheelchair and made her speech quiet and hard to understand. When she was in a crowd, it was hard for her to navigate through it because people did not see or hear her.
I built her a simple two transistor siren that could be attached to the chair and was operated by pushing a momentary push button. When people heard that siren (it was not loud) they moved out of her path. She was tickled with it.
That was one my first few circuits too. Much before I studied engineering, since my childhood I was passionate about building small electronic gadgets by referring to books/magazines which used to publish hobby circuits. Even though I did not fully understand how that circuit worked, I built that circuit with two transistors and a small speaker form an old radio. My friends and I had fun with that for some time.
In a Strategy Analytics survey, 40% of Americans said they were not at all interested in fully autonomous driving. It's hard to picture those opposing gun control abdicating the freedom of turning their own steering wheel.
Verification remains a key issue in system-on-chip development. The time taken to verify a high-density SoC design to a high level of confidence can lead teams to think the unthinkable. One of these counterintuitive options is to not exhaustively verify a chip before taping out but use the resulting silicon itself as a cornerstone of the verification process.
Work by a team at the University of Oxford and the University of Exeter may well become recognized as the first steps on the road to a new and bright optoelectronic future for phase-change memory materials.
