Fill in Gaps in Pear Note

If you ever find yourself zoning out during a meeting or class, only later to realize that you forgot to take notes for 20 minutes, Pear Note makes it easy to fill in those gaps. To do so:

  1. Open your Pear Note document.
  2. Hit play.
  3. Click on the last text you did type to jump to that point in the recording.
  4. Click the lock to unlock the text of the note.
  5. Take notes on the part you missed.

Your new notes will be synced to the recording just as if you'd taken them live with the rest of your notes.

Researchers Demo Devices Powered by TV Signals

According to this MIT Technology Review article, researchers at the University of Washington have developed prototype devices that communicate using just ambient radio waves — no batteries needed. The devices achieve this trick by varying how much they reflect and absorb radio waves, and scavenge power from those same radio waves. Bandwidth is low — only about 1 kilobit per second — and range is currently less than 1 meter, though that can reportedly be extended to about 6 meters easily. By eliminating batteries, such devices can become significantly smaller and cheaper, and could appear in a wide variety of scenarios, from contactless payments to warehouse item tracking, plus the killer app of locating your glasses and keys.favicon follow link
