Talk softly, but equip a large aerial

The University of Washington has developed Passive Wi-Fi. A method of generating 802.11b transmissions using backscatter communication, while consuming 10000 times less power than existing Wi-Fi chipsets (and 1000 times less power than Bluetooth or Zigbee) Passive Wi-Fi transmissions can be decoded on any Wi-Fi device including routers, mobile phones and tablets.

Pornoscan goes mobile

Thinking of not flying to avoid being scanned? Better not drive either: A breakthrough in X-ray detection technology, AS&E's Z Backscatter Van™ (ZBV) is a low-cost, extremely maneuverable screening system built into a commercially available delivery van. The ZBV allows for immediate deployment in response to security threats, and its high throughput capability facilitates rapid inspections. The system's unique "drive-by" capability allows one or two operators to conduct X-ray imaging of suspect vehicles and objects while the ZBV drives past. [more inside]

TSA gets Xray goggles. No, seriously.

Scanners that see through clothing installed in US airports. Good news! No more testing. Time to roll these puppies out. It's OK though, seriously guys. See we're gonna blur the faces when we look at their sexual organs, so everything's cool. K? Prev.

Oh, I wish we had the image tag again...

Bare naked travel? (Previously on MeFi: here, except now they're actually doing it, and here). The TSA wants to see you naked. Just don't paint "Kip Hawley Is An Idiot" on your torso in Pepto-Bismol before you go to the airport.
