Google's self-driving cars can read cyclists' hand signals
Google is working to expand the capabilities of its self-driving vehicle fleet, and according to its latest progress report (PDF), it's making strides in sharing the road with cyclists. One of the ways the folks in Mountain View are doing that is by using onboard sensors to gauge and interpret a cyclist's intent. "Our sensors can detect a cyclist's hand signals as an indication of an intention to make a turn or shift over," the company's June autonomous vehicle report reads. "Cyclists often make hand signals far in advance of a turn, and our software is designed to remember previous signals from a rider so it can better anticipate a rider's turn down the road."
Garmin's Varia radar warns cyclists about traffic they can't see
Six months. That's apparently how long it takes to buy a company, retool their product, and sell it under a new name. Garmin's new Varia Rearview Bike Radar is a rear light that scans up to 140m behind a bicycle for traffic. It then hands that data on to either a compatible Garmin Edge system or a standalone handlebar-mounted unit with an array of lights to warn riders of what's behind them and how fast it's approaching. If you're a keen cyclist, this idea may sound a little familiar. Startup iKubu made a little splash last year with Backtracker, which was essentially the same thing but a little rougher around the edges. Garmin bought the company back in January, and apparently wasted no time turning the Backtracker into what you see above.
Ben Heck cooks up proximity sensor for cyclists, still no substitute for keeping eyes open
Ben Heck's been busy -- again. In the latest episode of his bi-weekly show he puts his considerable brain power to work on cycle safety. He uses Parallax ping sensors connected to an Arduino to measure whether you're in any danger from nearby obstacles and traffic. The red and green LED indicators are hooked up to ambient light sensors so they don't blind you while riding at night -- looks like Mr. Heck's thought of everything. This week's episode also includes more secrets behind the prolific modder's Android APK-based baby seat. Check out both projects after the break.
Apple patent application details iPod / iPhone bike integration system
Apple patent applications can be a little out there sometimes, but this one makes so much sense we have to wonder why it's not a product already. Described as "Systems and Methods for Integrating a Portable Electronic Device with a Bicycle," the application details what basically amounts to Nike+ for bikes. That includes the ability to relay data from bike sensors to your iPhone or iPod, which you'd be able to view on the device itself or on an external display of some sort -- the application even goes so far as to mention the possibility of a heads-up display, although we wouldn't get our hopes up for that. What's more, the application also suggests that the system could communicate and share information with other nearby cyclists, and it would apparently include some fairly extensive GPS capabilities (on the iPhone, at least), including turn-by-turn directions to help you find a specific bike route, and maps complete with reviews from other cyclists.
Garmin debuts Edge 500 GPS for bicyclists, determined unicyclists
Garmin's cyclist-minded GPS devices have sure come a long way from their earlier, bulkier days, and it looks like the company has now produced one of its sleekest units to date in the form of its new Edge 500 GPS. Like most such devices, this one is primarily intended to track your cycling progress rather than lead you to your destination, and it promises to give you precise data on things like speed, distance, time, calories burned, and even climb and descent information, which is further bolstered by a built-in barometric altimeter to pinpoint changes in elevation. The unit can also sync up with various third-party devices that make use of ANT+ technology, and it can naturally be paired with a Garmin heart rate monitor to keep a close watch on your vitals. Look for the standalone unit to set you back about $250, while the bundle with a heart rate monitor and speed/cadence sensor bumps things up to $350.
5 Apps for the cyclist
Apple products and the bike go together well. They seem to appeal to the same sort of folks: evangelistic, committed aficionados willing to pay any premium, to be brutally honest about it. Oh, and let's not forget, they love to talk at length about these objects of their affection at parties. You know who you are. You've got a copy of Colorado Cyclist in your bathroom. So it seems like getting the iPhone working for you on the bike would be a no-brainer. And it pretty much is. Here are five apps that I've found I like, most centered around the fact that the iPhone's built-in GPS gives cyclists the kind of on-bike information they want, and the après vélo experience they crave until the next fix, I mean "ride." From the outset, you'll need a bike mount, if you want to take advantage of these apps' functions en route. Otherwise, the iPhone slips just fine into a jersey pocket, and will hold a GPS lock even though a ziploc sandwich baggie. Mount-wise, pickings are slim, but there are a few out there that are relatively low-profile. Plus, battery life can be a problem. Most endurance athletes are out there for hours at a time, and GPS tracking can quickly drain an iPhone battery. if you take care to turn off everything non-essential, you may be able to get that whole ride in. Or, you can do what this guy is doing; he's building an iPhone bike mount with power. Maybe now the iPhone can make its RAAM debut. On to the apps! 1) Ascent Mobile. I have a warm place in my heart for Montebello Software's Ascent. If I harken back to the old days, Garmin could barely be bothered to come out with a Mac version of its then-popular TrainingCenter software and had shunted all its Mac users to MotionBased. Ascent came through with elegant desktop software that tapped into the data side of the bike geek. Finally, a place to really churn through the routes and elevation, while watching your heart rate, speed and cadence throughout that quad-shredding ride. You can zoom right into your loop post-ride and slice and dice the data to see any element of it you like. What's more, Ascent really made it look good. By the time Garmin came out with its watered-down and feature-hobbled Mac version of TrainingCenter I was so over Garmin software. I used it strictly for the route-upload function and kept everything else on Ascent, with an online version stored on MotionBased for route sharing (though I've since moved from MotionBased to RunningAhead now that RA has GPS upload.) So I was thrilled to hear that Ascent was coming out with Ascent Mobile, $9.99US. Ascent Mobile gives you all the relevant data you could want on a ride, plus lots of ways to check out your ride right on the iPhone afterward. Best of all, it naturally syncs with the desktop version of Ascent, sold separately. Can I let go of my trusty Garmin Edge 705? Quite possibly. We'll see where this little relationship goes. (Oh, and yes, Erica, it gives your max speed.) 2) B.iCycle. Ok, maybe you're more of a "just the facts, ma'am" kind of rider. We've got one for you, too. B.iCycle, $9.99US, is a simple, GPS-based tracker that gives you some easy stats during your ride. It saves your tracks for later viewing on a map, and gives you all of the essential features you might want, without too much feature clutter. It has a nice map view for on-bike routing, and a way to email your route to yourself afterward. Think of it as a very inspired bike computer. 3) Bicycle Gear Calculator. Ok, grease monkeys, this one is for you. It's obviously not intended for on-bike use, but half the fun of the sport is the tinkering you get to do with your bike while you're not on it, talking about it at parties, or relentlessly reloading chainlove.com for the next steal. Now you can talk gear ratios with ease. Input chainring size, sprocket size, and crank length and all the relevant math is done for you. Plan ahead for a big hill ride and get your bike properly geared so you look like Laurent, Stefano, or Marco (may he rest in peace) on those hills. $4.99US at the iTunes store. 4) iMapMyRide. iMapMyRide is another GPS tracker, but is borne out of the website mapmyride.com, which is the sister site to mapmyrun.com, a favorite of mine, pre-Garmin Forerunner. The nice thing about this app -- other than the fact that it's free -- is that it is built to work well with the website, which is a great place to discover new routes and make connections with other like-sported people. I can't say the app itself is revolutionary in any way, but if you're already multi-sport and have been taking advantage of the MapMyFitness community-based functions, iMapMyRide may be a useful way to go for you. 5) TrailGuru. I didn't want to leave the mountain bikers completely out of the loop, so here's something for you singletrackers. I'm not entirely sure how this differs from some of the other GPS-based tracking software, but the community associated with it seems to be more interested in off-road use, so you may find that you discover new and interesting ways to tear up the trails near you. It seems to be a fave around TUAW, so I'd be remiss not to mention it. If you have experience with this app, let us know in the comments. I'm still working on integrating the iPhone into my fitness endeavors. I admit I love my Garmins (yes, I have both the Edge and the Forerunner.) And I can't imagine I'd be brave enough to do with my iPhone what I did with my Forerunner 305: put it under my swim cap at the start of a triathlon. But you never know. If you ever see a fellow race participant with what seems to be a very oddly-shaped head under that swim cap, come and introduce yourself to me.
Intersection sensor activator puts an end to cyclist discrimination
You're a good person with noble motivations -- you ride a bicycle instead of driving because it's healthy and it doesn't have a disastrously negative impact on the environment. We salute you, but not all of society appreciates your virtue like we do. In a sinister and systematic oppression of cyclists (we're absolutely certain it's intentional), many traffic lights are governed by sensors in the pavement that give a green light only after they've detected the change in inductance when a large metal car pulls up. Before you take up arms, though, take a look at this recently-patented device that sends out a signal that fools the sensors so cyclists don't have to wait for a car to unwittingly play good Samaritan -- we suppose we'll try this out just in case before we incite a violent revolution.[Via Core77]
SoundofMotion keeps cyclists safe, morphs phone into motorcycle
It may not be legal in most civilized nations to ride a Segway on the sidewalk, but for those still risking their lives on a two-wheeled machine, things are about to get a lot safer. SoundofMotion has developed a clever new warning system that turns your phone into what sounds like a roaring motorcycle, and not content with just playing a pre-recorded loop over and over, it's actually designed to rev up and down based on the speed and acceleration of your bicycle. The application will run on "any Bluetooth- and Java-capable phone," and it interacts with a "wireless BT sensor" that gets mounted on one of your wheels. Unsurprisingly, the device responds to the motion sensor and lets the carefree motorists around know you mean business when crossing an intersection. The app is currently sitting in beta, but the creators hope to have a final rendition ready to go before you make too many summer treks, but you better be willing to face total embarrassment (and have one loud speakerphone) to save your skin before picking this up.
