Toyota takes self-driving step with patent for eyelid detection device

With the rise of smartphones and more advanced auto infotainment systems, combatting distracted driving is a growing concern. One day, fully autonomous vehicles could end the problem, but that solution is still at best years away for consumers. Until then, automakers are working to make the tech safer, and one way to do that is monitoring drivers' eyes to make sure they're paying attention. With a recent patent, Toyota thinks it can make the tracking work even better. In Japanese brand's patented solution, a camera constantly monitors the driver's upper and lower eyelids and uses the data to calculate how open the eyes are. The company admits systems like this already exist elsewhere, but they can sometimes return false results by detecting redeye instead of the location of a person's actual eyeball. To fix this, the automaker adds a further step to search for redeye. If it occurs where skin is already assumed to be, then the system can go back to tracking the accurate location of the eye. Toyota doesn't specify how it might use this technology, but more accurate data would always be useful. The company wouldn't be the first automaker to work on implementing eye detection, either. For example, General Motors has a pilot program using it to monitor distraction, and Jaguar Land Rover watches a driver's peepers to create the 3d image for its Virtual Windscreen. Related Video:

Lexus Eco Challenge rewards schools for clean water, briquette press projects

Teams from one New Jersey high school and one Michigan middle school reversed the old adage by thinking locally and acting globally. And that strategy won them the grand prizes in the most recent edition of the Lexus Eco Challenge. The future is indeed bright. The Toyota luxury-vehicle division gave out a half-million dollars in this year's contest. One $30,000 grand prize was awarded to the Pinelands Eco Scienteers from Little Egg Harbor, NJ, which produced and distributed low-cost briquette presses to rural villages beset by deforestation. The other grand prize went to the E.T. Electrical Team from Byron Center West Middle School in Michigan. That middle-school group raised money to send water filters to Haiti, Kenya and the Philippines. Lexus also awarded eight $15,000 first-place awards, with the winners including high schools from California, Florida, Missouri and Pennsylvania as well as middle schools from Arizona, Michigan, North Carolina and Texas. A special shout out goes to Daniel Boone Area High School in Birdsboro, PA, where students created an educational and public-relations campaign to publicize algae-based biofuels. In all, Lexus has doled out more than $4 million in Eco Challenge awards in seven years. Check out Lexus's press release below. Students Get Dollars and Sense in Lexus Eco Challenge - $500,000 Awarded to Teams Who Learn About Environment and Community Empowerment Two Grand Prize Teams Earn $30,000 Eight $15,000 First Place Awards Given to Innovative High School and Middle School Teams Students Bring Ideas to a Larger Audience and Make a Positive Impact on the World TORRANCE, Calif., (Feb. 24, 2014) – It's a win, win situation! Communities become a better place, and students, teachers and schools have the chance to share $500,000 in scholarships and grants through the Lexus Eco Challenge.

The Lexus Eco Challenge is an educational program and contest that inspires and empowers young people to learn about the environment and take action to improve it. High school and middle school teams nationwide define an environmental issue that is important to them, develop an action plan to address the issue, implement the plan, and report on the results.

How Toyota's Le Mans racer may make its next Prius even better

The supercapacitor technology in the Toyota TS040 "offers great possibility for production car use." – Amanda Rice, Toyota Pop-culture junkies familiar with 1980s touchstone movies will hear the word "capacitor" and think Back to the Future. But the concept of supercapacitors being used in upcoming production models is being pushed by Toyota, not DeLorean. And because of that push, the future might look a little brighter for the Prius. The Japanese automaker will likely apply electric-motor technology used in Toyota's 24 Hours of Le Mans entry – the TS040 – in future versions of the world's best-selling hybrid, Australian publication Drive.com.au says, citing an interview with Toyota Motor Sports' Yoshiaki Kinoshita. Specifically, the racecar uses supercapacitors because they're effective at storing energy created when the vehicle is under braking, only to quickly redistribute it on demand for rapid acceleration. Kinoshita said Toyota may apply this technology to the Prius within the next five years. While declining to comment on specifics, Toyota spokeswoman Amanda Rice tells AutoblogGreen that the Le Mans vehicle "represents an advanced vehicle laboratory for hybrid vehicle and component development. The supercapacitor technology used in this vehicle with its fast charge and discharge capability offers great possibility for production car use." In her email, Rice added that the next-generation Prius will have smaller electric motors with greater power density and thermal efficiency, so let's add that to what we know or think we know about the fourth-generation model. Toyota entered two vehicles in this year's Le Mans race, and one of them had secured the pole-position and was leading much of the race before calling it quits 15 hours in because of electrical issues. Audi ended up winning the race, marking its 13th victory in the history of the French endurance contest.
