Baggage Scanning Technology Evolving

The latest in baggage scanning technology looks kind of like the CT scanner hospitals use to to look inside the human body much like a loaf of bread, one slice at a time. Transportation Security Administration (TSA) officials hope this new tool will do a better, faster job detecting explosives in baggage.

The Explosives Detection Systems (EDS) machine runs with CT scan technology, modified to detect explosives in baggage and taking the place of TSA agents manually swabbing each bag. Fully-automated, the machine can scan at the rate of 240 bags an hour. TSA has installed 455 of the machines in airports since January.
Rather than multiple 2D images in traditional x-ray scanners, this new generation CT-like scanner displays dynamic images using a baggage scanning technology called Array Motion Imaging (AMI). AMI presents a moving image of baggage to the machine operator, as though someone were turning it around from side to side or up and down, enabling them to see all areas of the bag.

In the past, careful packing might have allowed prohibited items in baggage to pass by TSA machine operators not “seeing” them. This scanning technology lowers the odds of that happening substantially with new, multiple views as baggage passes though the system.

“It can be deployed anywhere,” said Jeffrey Allison, TSA acting federal security director told thenewsstar.com. “It is portable and can be moved from one location to another. It is a great service for the passengers and it reduces the number of false-type alarms.”

Built by Reveal Imaging, the $340,000 EDS machines are being paid for with funds from the American Recovery and Reinvestmant Act of 2009, a $30 million fund earmarked to improve airport security across the nation in all areas.

TSA began using advanced imaging in 2007. An evolving program, imaging can detect a wide range of threats to security in a matter of seconds to protect the flying public. Imaging is an integral part of TSA’s effort to continually look for new technologies that help ensure travel remain safe and a step ahead of evolving threats.

The TSA imaging program encompasses more than just baggage, it also includes the “scanning” of people as well. Too big to fit through a machine, human beings are handled differently, using a a variety of non-invasive methods that are preferred over unpopular pat-downs.

Since imaging technology has been deployed at airports, over 99 percent of passengers choose to be screened by this technology over alternative screening procedures. According to a CBS poll, 4 out of 5 Americans support the use of advanced imaging at airports nationwide.

Additionally, passengers with joint replacements or other medical devices that would regularly alarm a metal detector often prefer this technology because it is quicker and less invasive than a pat down.

“We are always looking for new technology and procedures that will both enhance security while strengthening privacy protections,” TSA Administrator John Pistole said.

2011 Iditarod begins today

The 2011 edition of the Iditarod Trail Sled Dog Race gets underway today in Anchorage, Alaska, where 62 mushers, and their teams of dogs, will set out on an 1131 mile journey to Nome. The event, which is billed as “The Last Great Race,” is an annual test of stamina and skill for both the dogs and their drivers.

The Iditarod was first run back in 1973 and over the years has easily become the most popular sporting event in Alaska. The event pays homage to an historic sled dog run that took place in 1925 in which teams of mushers raced against the clock to deliver a lifesaving diphtheria serum to Nome at a time when many children were stricken with the disease. Norwegian Gunnar Kaasen and his lead dog Balto became well known celebrities for completing the final leg into the town with the medical supplies in tow.

Today, the ceremonial start to the Iditarod will take place on 4th Avenue and D Street in Anchorage, where large crowds will gather to see the teams off. The real race gets underway tomorrow however, when the action moves to Willow. From there, the competition will truly get underway, with the top mushers expected to arrive in Nome in about 10-12 days depending on weather conditions.

The field is full of experienced teams, but the man to beat is still Lance Mackey, who is the four-time defending champ. Mackey and his dogs have easily been the fastest team over the past few years, and until someone steps up to take the crown, he’s still the odds on favorite. He may be challenged by 23-year old Dallas Seavey however. Seavey, who placed eighth last year, recently won the 1000-mile long Yukon Quest, and seems to be an emerging force in the sport.

Good luck to all the mushers and their dogs. Race well and stay safe on the trail.

Photo of the day – Philadelphia skyline

Today’s Photo of the Day is of a piece of the Philadelphia skyline, anchored by the 1930 PNB Building. It was taken by Christian Carollo Photography.

A few years ago, Philadelphia suddenly started cropping up in the travel media as a bypassed destination, as a place that was finally getting the attention it had deserved all along. This development accompanied a spate of stories about the evolution of Philadelphia as the “new” or “next” Brooklyn.

Philadelphia is just one of many North American cities that has fallen by the wayside in the public imagination. Cleveland, Detroit, Cincinnati, Winnipeg, and Indianapolis are right up there with Philadelphia, each for different, contextually specific reasons.

Got an image of a secondary North American city that doesn’t get the press it deserves? Upload it to the Gadling group pool on Flickr. If we like it, we might very well choose it as a future Photo of the Day.

Winter in Alaska: Paws for Adventure dog mushing tour through Fairbanks (video)

In the spirit of journeying during periods less traveled, I’ve embarked to Alaska this winter. Follow the adventures here, and prepare to have your preconceived notions destroyed along the way.



Video footage from my one hour Paws for Adventure dog sled tour in Fairbanks, AK

The more time I spent in Alaska during the winter, the more I asked myself why this wasn’t considered a tourist season. A week or so ago, Fairbanks was gifted with an atypical dumping of fresh powder, making the conditions more than perfect for a day of dog mushing. Following the races down at Fur Rondy, I headed up north to Fairbanks for a slightly different kind of dog race: one that began and ended at a homestead. Paws For Adventure is an Alaskan outfit that uses their stable of dogs strictly for casual runs — nothing competitive whatsoever. These pups were downright adorable, and I was able to sit down (with owner Leslie Goodwin) in a sled behind ten beautiful dogs. They hauled us along like champs, and they were thrilled to be doing it. I couldn’t help but make a few rounds praising them all afterwards, and even now, it’s one of the highlights of my trip to The Last Frontier. If you’re looking for a truly Alaskan adventure to partake in whilst in Fairbanks, look no further. Have a peek at the video above to get a gist of what to expect.

Tutorial: how to properly shoot / photograph the Northern Lights

In the spirit of journeying during periods less traveled, I’ve embarked to Alaska this winter. Follow the adventures here, and prepare to have your preconceived notions destroyed along the way.

Ah, the Northern Lights. Aurora Borealis. Pure magic. Regardless of what you call them, these mysteries of our universe are truly impossible to forget once you see them, and now that I have, I totally understand why people plan entire trips around the sliver of a chance to witness them with their own eyes. The Northern Lights don’t come out for humans to see that often, but February and March are considered prime viewing months in the frigid wilds of Fairbanks. The northern half of Alaska is one of the only places in America where you stand a chance at seeing this phenomenon yourself, and it’s yet another incredible reason to visit The Last Frontier in the winter. Seeing these colored swirls dance across a starry Alaskan sky stirs the soul like few other experiences can, and if there’s one thing you’ll want to do when spotting them, it’s capturing the moment for years to come. Photographing the Northern Lights is no easy task; it’s more like a science, but it’s far from impossible. Read on to learn how I was able to capture the images seen here in the gallery on one bone-chillingly cold night north of Fairbanks.

%Gallery-118384%For one, it’s important to position yourself in a place that’ll provide the best possible chance to spot the Northern Lights. The Northern Alaska Tour Company runs overnight trips to Coldfoot and Wiseman for this very purpose, and Chena Hot Springs Resort — located some 60 miles from the city lights of Fairbanks — also has a specific area setup to view them. But of course, they don’t emerge every single night, and their appearance is both varied and unpredictable when it comes to timing. You can read more on exactly where I camped out to capture these shots here, but the long and short of it is this: Fox, Alaska is just far enough away form Fairbanks to get a non light-polluted view of the sky, and Goldstream Road is known by locals as having great vantage points. If you’re looking for an easy spot to go in your rental car, Fox is it. Here’s a more detailed look at how to reach this spot.

Now, for the equipment. If you’re making the effort to capture the Northern Lights, you’ll need to come prepared. Being that it’s the winter, you’ll need to dress in pretty much everything you have. Spotting the lights requires patience and time. I started my campout session at 1:00am in early March, and didn’t see any activity until 1:40am. Once you see any activity at all, you’ll need to move fast. I saw them dance for around 60 minutes before vanishing, but there are no guarantees that you’ll see them hang around for that long. Heavy coats and pants, thick socks, a face mask and hand warmers are all a must.

Here’s a breakdown of what camera gear I’d bring when camping out to see the Northern Lights:

  • A DSLR (two if you have them!); the nicer the model, the better. My gallery here was composed with a Nikon D3S and a Nikon D90.
  • A sturdy tripod. This is essential. I know it means you’ll need to check a bag, but you simply have to have a tripod for each camera.
  • Wide-angle lenses. Dedicated wide-angle lenses (like Nikon’s 10-24mm DX lens) capture the widest amount of sky, but even a standard lens (like the 24-70mm FX lens) is “wide enough” for most.
  • Fully charged batteries. -20 degree temperatures can zap a battery in no time, so make sure you’re at 100 percent before leaving home. If you have spares, bring them!
  • Flexible gloves. You’ll need to be able to tweak your camera settings, so make sure you wear gloves that allow you that luxury.
  • A remote shutter. This is optional, but having a remote to activate each shot means less opportunity for blur in long exposure shots.
  • A flashlight / headlamp. This is super useful for lighting up the buttons on your camera so you can tweak settings in the dark of the night.

So, that’s about it as far as kit. Now, let’s talk settings:

  1. Widen your lenses as far as they’ll go — you want a vast image, and having the ground / surrounding buildings visible on the lower portion of the shot provides outstanding scale and context.
  2. Place your DSLR in full manual mode; you’ll want total control over every single aspect of these shots.
  3. Switch each lens to manual mode, and dial your focus ring to Infinity. Be careful to align that Infinity symbol precisely (rather than just cranking the focus wheel past it).
  4. Lower your aperture as far down as it’ll go. I’m talking f/2.8, f/3.5, etc. Whatever your lens will stop down to.
  5. Lower your ISO to 200 – 1,000. This varies greatly depending on the camera, so you’ll need to start at 200 and raise it notch by notch if your shots are simply too dark.
  6. Adjust your shutter speed to 30 seconds. If your camera will only go to 20 or 25 seconds, you can probably make that work as well. Those with a remote shutter can use “Bulb” mode for even longer exposure shots, but remember, the longer you leave that shutter open, the lower your ISO needs to go (and / or higher your aperture value needs to be) to prevent too much light from “whiting out” the shot.
  7. Set your file capture type to RAW! This is an extremely vital step. Feel free to shoot in RAW + JPEG if you want both, but RAW files grab the rich blackness of the sky far better than JPEG will.
  8. Align your shot on the tripod. Peek through the viewfinder and make sure you’re getting the angle you want; I’d recommend various portions of the sky to be in various shots to add some variety.
  9. Gently press the shutter button, and remain still. Even the slightest shaking of the ground could introduce unwanted blur into your shots, so it’s important to remain still as the long exposure takes place. You can dodge this by using a remote shutter from a distance away.
  10. Evaluate your results. If it’s too dark, bump the ISO value higher or lengthen the exposure time (i.e. shutter speed) beyond 30 seconds. If it’s too light, raise the aperture value a notch or two or bump your ISO value closer to 0. You could also slow the exposure, but I’d use that as a last resort.

The only other major advice I have is to shoot a lot. A whole lot. You aren’t guaranteed to see the Northern Lights, so if they come out, you need to be quick in your setup procedure and continually fire shots in hopes of grabbing a handful of keepers. You also cannot assume that you have “one great shot” based on what your see on your DSLR’s LCD. Those are often misleading, and can hide subtle amounts of blur that’ll show up later. Take as many shots as you can stand to take, as each one is guaranteed to be somewhat different than the last. If you execute the shoot properly, you won’t have to fiddle much with the shots in Photoshop afterwards. The Northern Lights pretty much accentuate themselves. I’d also recommend a lot of patience, and if you don’t see them on your first night out, try again. Trust me, it’s totally worth the effort.
