The latest advances in inflatable head barriers are now permitted in cars sold in the U.S. The National Highway Traffic Safety Administration (NHTSA) has revised its standards for preventing head injuries during side-impact and rollover accidents. In 1995, NHTSA issued rules for adding protection to the heads of passengers beyond what is provided by forward-mounted airbags. At first, most car makers planned to meet the requirement, which began phasing in this September 1, by adding padding to the upper interior of cars. In the interim, however, design engineers devised devices similar to airbags that expand across the roofs of cars in accidents. A problem is that the devices won't deploy through heavy padding. So NHTSA decided on a tradeoff. It will reduce the speed used in crash tests of cars with the devices in uninflated states, in favor of the bigger benefits offered in more severe crashes. But vehicles equipped with such systems also will have to comply with a new test in which the vehicle is crashed into a pole. NHTSA will use a new side-impact crash dummy in the pole test. The head injury rule applies to 10% of 1999 models, but will apply to 100% of year 2003 production models.
Smart move guys. Thanks to the NHTSA people, they are truly heaven sent and their decision to improvise the standards for safety gear kits is super awesome. I am a law abiding citizen and prefer to wear helmets while driving. My helmet is SmartShieldz brand. They make pretty safe helmets.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
