An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.

The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car’s speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.

Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use:“Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”

The product will soon go on sale in Sydney.

Electrical devices(仪器)could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking , British scientist Max Donelan and other scientists in Canada and the United States developed the device.

The device connects to a person’s knee. As the person walks ,the device captures energy each time the person slows down. To do this ,the device helps with the slowing sown movement of the leg, the movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.

There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also he used in hospitals to operate heart pacemakers(起博器), it could even be used to assist in the movement of robotic arms and legs.

The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy, but the researchers hope to make a lighter, less costly version, An improved version should be ready in one year.

The developers hope the device will one day help developing countries; nearly twenty five percent of people around the world live without electric power.

A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania, He created a bag carried on a person’s back that also produces power from walking. The knee device does not produce as much electricity as the bag, but the bag requires the walker to carry a load of twenty to thirty kilograms.
