During infancy, a baby's brain maps a mother's moving lips to the sound of her voice with the superior colliculus portion of the brain, which associates external direction with an internal visual reference guide. Researchers at the University of Illinois are using that idea for development of a new self-aiming camera that could help the military distinguish a flock of geese from a fleet of MiGs. "The superior colliculus serves as the visual reflex center of the brain," says Sylvian Ray, a UI professor of computer science. "It is the primary agent for deciding which direction to turn the head in response to sensory stimuli," he says. The system includes microphones and two cameras. As the camera detects motion by comparing successive frames, the system monitors audio signals from the omni-directional microphones. Sound location algorithms analyze the sound and send information to a neural network. A second camera equipped with a long-range lens determines the position of the target. Ray says the combination of sight and sound offers a stronger stimulus than each individually. For more information, go to www.uiuc.edu.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
