Researchers have created a backpack that has a computer and medicines in it that can help even untrained soldiers save the lives of wounded troops. Wounded soldiers have a better chance of survival if they get help soon after being hurt and are quickly taken to a hospital or clinic. But soldiers who do not have medical training may not know how to help their injured friends.
Doctors and engineers have developed what they call an “intelligent backpack”.It has a computer and electronic measuring devices. The backpack also has robotic instruments and medicines ready to give to injured troops.
About 16 doctors and engineers from the University of Pittsburgh, Carnegie Mellon University and several other places are working on the project. The U. S. Department of Defense has given money to the project.
Ron Poropatich leads the project. He is a retired army surgeon. He says the backpack will help soldiers care for those who are injured. The devices included in the backpack can monitor a person^ heart rate and blood pressure. The robotic instruments can even tell whether the soldier has a collapsed lung.
The intelligent backpack's computer can compare information gathered about the injured soldier with thousands of similar cases, and quickly tell the best methods to use to save the soldier’s life.
Sometimes, it is not always possible to quickly remove the injured soldier from the battlefield.So,Dr. Poropatich says, the researchers hope to create a backpack that will have devices .that can keep a .soldier alive for a long time. Dr. Poropatich hopes the backpack and its instruments will be ready for testing animals in about three years.

【推荐1】Remote controls are one of the most common symbols of our modern technologies. In fact, remote controls are an invention born in the 1800s. Famous inventor Nikola Tesla created one of the world’s first wireless remote controls, which he exhibited in public at Madison Square Garden in New York City in 1898.
Tesla called his system a “teleautomaton”, which could be used to control a mechanical device. For his demonstration, Tesla employed a minitype boat, which had a metal air wire that could receive exactly one radio frequency. He showed how his remote-controlled boat worked and whole process attracted many people. However, financially, Tesla’s remote-controlled boat was a failure. His intended client, the U.S. Navy, thought the technology was too easily damaged during use. But the concept of remote control caught on and quickly spread to many other types of equipment.
In the 1930s and 1940s, a new consumer electronics, such as garage door openers and model airplanes, arrived with remote controls. In the mid-1950s, Zenith engineer Eugene Polley designed his Flashmatic TV remote control, which used directional flashes of light to control the television. In 1956, Polley’s colleague, Robert Adler, created the Space Command control, which employed high-frequency, ultrasonic (超声的) sounds instead of light. This style of remote control increased the price of a new TV by a third, but that didn’t stop people from buying in mass quantities. Remote controls kept evolving, too. Ultrasonic sound remote controls were the standard for TVs until the 1980s, when remote controls began using the infrared (红外线) light signals that are very common today.
These days, you can find remote control capability built into a huge array of products such as toy cars and helicopters, video game consoles (控制台), ceiling fans, etc. There’s a good chance you can find a version that’s controlled by remote control. You can even buy a remote-controlled toilet.
Remote controls have allowed humans to perform many tasks that would be difficult, if not impossible. And although remote controls have a long history, they are anything but over. As we continue to introduce technology to every aspect of our lives, it’s very likely that we’ll need remote controls to keep things under control.

【推荐2】Baggy has become the first dog in the UK—and potentially the world—to join the fight against air pollution by recording pollutant levels near the ground.
Baggy wears a pollution monitor on her collar so she can take data measurements close to the ground. Her monitor has shown that air pollution levels are higher closer to ground level, which has helped highlight concerns that babies and young kids may be at higher risk of developing lung problems.
Conventional air pollution monitors are normally fixed on lampposts at about nine feet in the air. However, since Baggy stands at about the same height as a child in a pushchair(婴儿车), she frequently records pollution levels which are much higher than the data gathered by the Environment Agency.
The doggy data research was the idea of Baggy’s 13-year-old owner Tom Hunt and his dad Matt. The English youngster noticed that pollution levels are around two-thirds higher close to the ground than they are in the air at the height where they are recorded by the agency. Tom has since reported the shocking findings to the government in an attempt to emphasise that babies are at higher risk of developing asthma(哮喘).
Matt Hunt said he was ”very proud“ of his son because “when the boy gets an idea, he keeps his head down and gets on with it, and he really does want to do some good and stop young kids from getting asthma.”
“Tom built up a passion for environmental protection at a very early age,” Matt added. “He became very interested in gadgets. About one year ago, he got this new piece of tech which is like a test tube. One Sunday afternoon, we went out to do some monitoring, and he said, why don’t we put it on Baggy’s collar and let her monitor the pollution?’ So we did it.”
Tom said, “Most of the time, Baggy is just like any other dog. But for the rest of the time she is a super dog, and we are all really proud of her.”

【推荐3】People who suffer from motion sickness have a long list of activities they are afraid of, and often avoid altogether. This includes long-distance airplane travel, road-trips, and even certain movies and video games. However, if the French company Boarding Ring has its way, motion sickness sufferers will soon have nothing to worry about, provided they are willing to wear the strange-looking Boarding Glasses!
Also called seasickness or carsickness, motion sickness is believed to be the result of the brain receiving mixed signals from the sensory systems, which include the eyes, inner ear, muscles, and joints. For example, when you are looking at your phone on a moving bus, your inner ear notices the motion but your eyes, focused on the screen, thinks you are not moving.
Boarding Glasses try to reduce motion sickness symptoms by “recreating the horizon” so that all the user’s senses send the same message. Though that sounds complex, the science behind the eyewear is surprisingly simple. The frames, made of two round lenses on the front and two on the side, are hollow and partially filled with a blue liquid. Any movement in the vehicle causes the liquid to run around the eyes. This allows the eyes to sense the motion and send the correct signal to the brain. Antoine Jeannin, CEO of Boarding Ring, says, “Your eyes always get the reality of the movement and get a signal that is consistent with the balance system perception.”
According to the company, Boarding Glasses, invented by Jeannin’s father, have been tested by French Navy personnel. The CEO says that over 95 percent of the users reported feeling better after wearing them. People who don’t like the glasses’ appearance will be excited to know that they are only required to be worn for a short period of time. According to Jeannin, “You put the glasses on at the first sign of sickness, leave them on for 10 or 12 minutes, and then take them off. Usually, this cures you of the sickness for the rest of the journey.” The best part is that since Boarding Glasses have no lenses, a single pair can be shared among a group of friends, or even an entire family!
