When does a stuffed Pooh Bear become a sensory stimulation activity center? When seniors and graduate students at Duke use their ingenuity to fashion devices that will meet the needs of care givers and special-needs children. Every year, students form design teams, each working within a $500 budget, using money provided by the National Science Foundation and the Duke Kids Care Fund. The Pooh team students started with a run-of the-mill Winnie the Pooh stuffed bear. Then they installed two fans in its head and a circuit board within its tummy. Also in its head they built a chamber for an air freshener cartridge. And on the outside of its tummy they installed a control panel with red, blue, yellow and orange buttons and associated lights. Each time infants push an orange circular button, they see an orange light and hear an electronic rendition of the Winnie the Pooh song. A diamond-shaped yellow button illuminates a yellow light and makes the animal vibrate an arm. A blue, square button causes the blue light to come on as the bear blows a puff of air through its mouth. The red triangular button illuminates the red light and emits a pleasant scent along with a puff of air. Other projects on this year's program included: An improved submersible wheelchair design, with larger wheels, better safety latches, and colors that are easier to see underwater; a re-engineered electric-powered feeding device; and a ceiling mounted wheelchair transfer hoist; special computer games that let disabled children catch butterflies and drive around obstacles, with the goal teaching joysticks skills for controlling electrically powered wheelchairs; and a 'child friendly' adjustable timer to help a 2-year-old learn to feed himself. Students say they relish the chance to apply their knowledge to real world problems with humanitarian objectives. For more information, contact Monte Basgall at (919) 681-8057.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
