Springs

You might laugh, but springs surround us. And they're not just supporting our beds, either: Springs are an integral part of really complicated technology and basic products we use constantly. So let's go through a few things you couldn't do without springs.

For one, you couldn't drive to work. Springs are used in your car's suspension system so that when you get in, hit a bump or carry a heavy load, you aren't bottoming out. You might not have been able to safely heat up your lunch in a microwave, either; snap-action switches are used in the door. These micro-switches (a popular name for them, trademarked by Honeywell) are made up of a plunger that harnesses the stored-up energy in a spring to snap, causing a movement. These switches are especially useful because they can be controlled by temperature or position.

Your thermostat, for instance, might employ a snap-action switch to turn the furnace on or off. When the temperature reaches a certain point (and our friend the spring is wound tightly), the plunger snaps, making the mechanism turn on or off. Your microwave uses it when you open the door as your pizza rolls are cooking; the snap-action switch uses our little spring to automatically cut power to the microwave so you aren't given a radiation dose.

Lasers

So they're not the James Bond-type devices that are used to cut people in half, and they're (very unfortunately) not light sabers. But you better believe that lasers are a ubiquitous part of daily life that you might not even realize you stumble upon.

First off, there are some more obvious ones -- laser scanners at the grocery store, for instance. Few of us actually realize that there are lasers making our DVDs play. Indeed, our DVDs are lined with microscopic bumps that will send information to a transmitter, which will then turn it into audio and visual form. But what reads these bumps, you ask?

That's right: lasers. The DVD player is outfitted with a laser that moves at a constant rate, reading the bumps of the DVD so you can enjoy watching your marathon session of "Deadliest Catch" from the couch. If you're going old school and listening to your old Backstreet Boys CD collection, you're also using lasers to read those. It may not be the most sophisticated or edgy use of a laser, but it is one you're using every day without thinking about it.

RFID

Unfortunately, a commute is part of many people's everyday experiences. Whiling away the hours listening to Top 40 Hits in traffic is bad enough, but some of us even have to pay for the privilege. Toll bridges and roads can make a bad commute miserable.

But an E-ZPass or an automatic tolling chip lets you fly through tolls without stopping and contorting yourself into strange positions in an attempt to get at the change on your floor. Many people don't recognize the technology they're using; it's called RFID (radio frequency identification). RFID works by using a small computer chip -- in this case, on your toll pass affixed to your car or license plate -- to communicate and hold information. Using radio frequency, an electronic reader that can see your pass or plate collects the information in your chip: your vehicle's registration, address and maybe even an account that you've set up to automatically pay your toll fees. Unlike UPC codes, RFID codes can also send out information, as well as store it.

You can learn a lot more about RFID here, but the technology is growing. Right now, you might be using RFID tags to check out books from the library if you live in Seattle or New Orleans.
