Florida had a bad hurricane season this year. Electricity went out for days. So did land-based phone service and cable networks. About all that worked were cell phones. But cell phones can be damaged by water. So, before the next storm season, take a look at the Nite Ize Boxit cell phone case. The case protects your phone from the severest elements; even if you drop your phone into floodwaters, the case keeps it afloat. You can dial, talk and hear through the case, but water and dirt can't get in. Cheap insurance at $36.95. Nite Ize Boxit www.niteize.com/boxit

Headphone Silencer
Scientists know that it's not sound that gets on our nerves; it's noise. From the drone of jet engines to the hum of tires on highways to the mechanical noises of copiers and office equipment, it's everywhere. How to shut it up? Bose now offers a headphone that combines listening to music with noise cancellation. Basically, a system measures noise frequencies in the air and then blocks them with countering frequencies. Silence results. (Hearing aids are getting better, thanks to these advances). The cordless Bose QuietComfort 2 acoustic noise-canceling headphones connect to an MP3 or DVD/CD player, silencing your environment and providing quiet listening. $299.

Wallpaper Defense
You may love your cell phone, but some businesses don't. Hospitals, airports, prisons, schools and movie theaters are cognizant that cell phones are the newest explosive detonation method. (Remember, cell phones triggered the deadly bombs on trains in Spain.) British company QinetiQ has developed a wallpaper technology so specific that it blocks cell phone frequencies but allows two-way radio signals to pass through. The blocking technology is not new-it's used in microwave oven glass-but until now, the material was too expensive to use on large surfaces. Contact QinetiQ directly to set up purchase and installation. QinetiQ wallpaper www.qinetiq.com
