"There are two types of communication technologies," says Alper Bozkurt, an assistant professor of electrical and computer engineering at NC State and co-lead author of a paper on the work. "One that allows us to communicate with the dogs, and one that allows them to communicate with us."
"Dogs communicate primarily through body language, and one of our challenges was to develop sensors that tell us about their behavior by observing their posture remotely," Roberts says. "So we can determine when they're sitting, standing, running, etc., even when they're out of sight – a harness-mounted computer the size of a deck of cards transmits those data wirelessly. At the same time, we've incorporated speakers and vibrating motors, called haptics, into the harness, which enable us to communicate with the dogs."
Keener and two colleagues developed and patented the radiant frying system in 2007. The radiant fryer uses infrared energy to produce the appealing crispy exterior unique to fried food.
Sixty-eight panelists were recruited on the basis of age, preference for fried chicken products, and a habit of eating "fast food" at least two times a month. The group consisted of students, employees and visitors of the Department of Food Science. Panelists rated randomly numbered samples of chicken patties on the basis of flavor, crispiness, oiliness, appearance and overall preference.
