The U.S. National Highway Traffic Safety Administration (NHTSA) attributes more than 100,000 crashes, including 1,357 fatal crashes and approximately 71,000 injury crashes annually, to driver drowsiness. At the 2005 Tokyo Motor Show, Denso unveiled its progress for using vision sensors to detect objects, pedestrians, and driver's condition. One vision sensor design is currently used in the Lane Keeping Assist system where drowsiness often causes drifting. In a conceptual approach, a vision sensor focused on the driver's face monitors the eyes and can detect inattentive driving caused by drowsiness by measuring how wide the eyelids are open. The technology can measure the blinking speed of a driver wearing glasses. Vision sensing, combined with electrocardiograph measurements made from electrodes installed in the steering wheel, provide a more detailed driver status.

Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
