ET DETROIT AP A cane equipped with the technology that retailers use totag merchandise could help blind people avoid obstacles. An engineering professor and five students at Central Michigan Universityhave created a ''Smart Cane'' to read electronic navigational tagsinstalledbetween buildings to aid the blind in reaching their destinations moreeasily. ''This project started as a way for me to teach students to see andunderstand the ways that engineering can be used for the greater good,''said Kumar Yelamarthi, the professor and project leader. ''We wanted to dosomething that would help people and make our campus more accessible. '' During the spring term, Yelamarthi and five senior engineering studentstested the cane, which is equipped with Radio Frequency Identificationtechnology, similar to what retailers put on products to keep them frombeing stolen. The Smart Cane contains an ultrasonic sensor that is paired with aminiaturenavigational system inside a messenger style bag worn across the shoulder. For the test, the students installed identification tags between twobuildings on the campus in Mount Pleasant, Mich. A speaker located on thebag strap gave audio alerts when the system detected an obstacle and toldthe user which direction to move. Students wearing glasses that simulate visual impairment tested the cane. The students also created a vibrating glove to assist those who are bothvisually and hearing impaired. Yelamarthi said it's one of the first outdoor applications of RFID and saidhe plans for students in upcoming classes to further refine the systemwhilehe seeks grants to speed the research.

I think of HUNKERED down as girding oneself to survive a long siege, like a Canadian winter or, even less fun, a stay in the fallout shelter out back. One may be hidden, but it's more of a side effect than the point. @anon12:27 I knew where you were going but enjoyed the ride. Nicely done. @phone users who comment That nifty "reply" feature where your comment appears immediately below the comment you are replying to does not work on any other platform. As a result, your conversational reply looks like a total non sequitur to everyone else. If you want us to understand your comments you need to, at a minimum, use the @ convention. As is not unusual, pretty much with Rex here. Well done for what it is, but I'm not much in to humor that was old timey when I was young. The puzzle has a certain Hee Haw/Lawrence Welk feeling to it. I did enjoy the WKRP clip.
