The next generation of smart phone could combine the date from its gyroscopes   with a built-in compass to allow you to track your indoor movements even without GPS.          Research described it in the international Journal of Innovative Computing and Applications by Shahid Ayub of Lancaster University, and his colleagues there and at HW Communications, suggests that the embedded inertial sensors   in many smart phones have added the facility to be used for localization and tracking applications. The primary benefit of using smart phones is that no additional infrastructure would need to be installed for monitoring personnel movements in a wide variety of situations not least staff, equipment and inventory movements in warehouse facilities, shopping malls and factories. In contrast, other technology being proposed would require new equipment,such as RFID technologies. However, smart phones do not yet have the ability to pinpoint their location without recourse to the GPS system, which is not accessible indoors and has the added disadvantage of using up battery power very quickly even if it could be used. Inertial navigation only provides the necessary information   to a specified starting point the team says. This is useful for anyone with a non-GPS smart phone who wishes to track the route they take when walking or jogging if they specify their starting point. The team suggests that pedestrians indoors could be positioned using a combination of the smart phone accelerometer   and an built-in digital compass, something that will become available in future smart phones. They have now investigated the potential of three different smart phone placement modes: idle, hand held and listening, which could be used with pedestrian dead reckoning (PDR) techniques to allow users to record the path they follow or for various kinds of workplace or other monitoring requirements. "The technique could be used in underground tube stations, airports , train stations where there is no infrastructure installed for tracking or... What is the primary benefit of using smart phones with embedded inertial sensors? A) They require new equipment, such as RFID technologies. B) They can track pedestrian movement indoors with GPS. C) No additional infrastructure would be needed. D) No additional money would be spent.

It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. "I'm going to college, but I need a way to pay for it," DeLuca recalls saying. "Buck said, 'You should open a sandwich shop.'" That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, buck wrote a check for $1000. DeLuca rented a storefront   in Connecticut, and when they couldn't cover their start-up costs, Buck kicked in another $1000. But business didn't go smoothly as they expected. DeLuca says, "After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls." All he and Buck knew was that their sales were lower than their costs. DeLuca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and brainstorm ideas for keeping the business running. "We convinced ourselves to open a second store. We figured we could tell the public, 'We are so successful, we are opening a second store.'" And they did--in the spring of 1966. Still, it was a lot of learning by trial and error. But the partners' learn-as-you-go approach turned out to be their greatest strength. Every Friday, DeLuca would drive around and hand-deliver the checks to pay their suppliers. "It probably took me two and a half hours and it wasn't necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out," DeLuca says. And having a goal was also important. "There are so many problems that can get you down. You just have to keep working toward your goal," DeLuca adds. DeLuca ended up founding Subway Sandwich, the multimillion-dollar restaurant chain. Which of the following is true of Buck? A) He put money into the sandwich business. B) He was a professor of business administration. C) He was studying at the University of Bridgeport. D) He rented a storefront for DeLuca.

The Gloria Barron Prize honors American young people from 8 to l8 who have shown leadership and courage in public service.Each year ten winners each receive$2,000 to support their higher education or their service work. Ellie Wen,18,was volunteering at a community center in Los Angeles.The center was set up to help immigrant families.She happened to meet adults in an EFL(English as a foreign language)class."When I saw them struggling hard,I wondered how people in poor countries could learn English,"Ellie said. So she started a Website,"Repeat After Us",where people can listen to English and practice their accents.Volunteers have helped Ellie record more than 6,600 texts,including Abraham Lincoln's"Gettysburg Address".  Hard work pays off.There were so many times that Ellie was discouraged,but she stuck to it.The Website crashed early on,and all the recordings were lost.But volunteers worked together vigorously to start over,and the visitors returned to the site. "Just follow your idea and know that the world is so kind.Even if you do have trouble,people will help you,"Ellie said. "I was really excited the first month,when we had 49 visitors,"she said.Now,more than 480,000 people from a11 over the world have visited the site."I get e-mails from China,Egypt,India,and Brazil."They say,"Thank you so much for this resource,we've been waiting for it for so long!"Ellie loves knowing she is helping so many people. Gloria Barron Prize winners like Ellie are enthusiastic about the work they do.And they encourage others to join in if they see a need.Anybody can be negative,but it needs somebody brave to be positive.Are you the brave one? Which of the following statements is true? A) The Gloria Barron Prize honors people showing leadership and courage. B) Each year ten winners share US$2,000 to support their higher education. C) Ellie Wen was badly paid at a community center in Los Angeles. D) People can practice their English via Ellie's website.
