| GPS Sunglasses | ||
| Sunglasses that contain both global positioning system components and cell phone services. |
Okay, so your sunglasses ring, you open them up and put them on. You see, projected on the lens of your sunglasses, whatever the other person is seeing (and presumably vice-versa). Not only that, the other person knows exactly where you are thanks to the GPS device built in to the sunglasses.

You're an engineer and you want to know it works? By all means, read this dense PDF - GPS Signal Availability in an Urban Area Receiver Performance Analysis.
In a hurry and you'd prefer to cut to the chase? Okay, it turns out that in urban environments subject to lots of signal shading, GPS signal availability can vary by 60%. You want details: try this:
"The results demonstrate the effectiveness of narrow correlator spacing technology in reducing the position errors caused by multipath from buildings in urban canyons."
