Robot vacuums have steadily improved their cleaning performance and object avoidance over the years, but during our testing at CNET Labs, we discovered an odd trade-off.

On the Move: How the MoDOT speed sensors work One of the technologies we use to determine traffic conditions is roadway sensors. They can sense everything from traffic speed to debris on the roadway.

Over the past decades, physicists and quantum engineers introduced a wide range of systems that perform desired functions leveraging quantum mechanical effects. These include so-called quantum sensors ...
