The wireless video camera is ________to send its video signa

Recently, scientists have developed a wireless brainmachine interface that help restore communication to people who can no longer speak by reading brainwaves using electrodes(电极) stuck on their heads. Unfortunately, these have proved very slow, at roughly one word typed per minute, making normal conversations and social interactions virtually impossible.
Scientist Frank Guenther and his colleagues reveal a brainmachine interface that uses electrodes implanted directly into the brain for research into real time speech.
"It should soon be possible for extremely paralysed individuals who are incapable of speaking to produce speech through a laptop computer, " said Guenther.
The scientists worked with a 26-year- old male volunteer who experience near-total paralysis due to a stroke he suffered when he was 16. They implanted an electrode that had two wires into a part of the brain that help plan and execute movements related to speech. The electrode recorded brain signals when the volunteer attempted to talk and the wires spread them across the scalp(头皮)to help drive a speech synthesizer (合成器). The delay between brain activity and sound output was just 50 milliseconds on average, roughly the same with regular speech.
"He was quite excited, particularly on the first few days we used the system, as he got used to its properties, " Guenther recalled." I am sure the work proceeds slowly from his perspective, as it does from ours. Nonetheless, he was very excited about getting real-time audio feedback of his intended speech and happy to work very hard with us throughout the experiments."
"The current system uses data from just two wires. Within a year it will be possible to implant a system with 16 times as many." Guenther said." This will allow us to tap into neurons(神经元)，which in the end means better control over a synthesizer and thus better speech."

Is it wrong to use someone else’s wireless (Wi-Fi) connection? Just recently, a man was arrested for doing just that. At that time, he was sitting in the street with a laptop(便携式电脑) and using an unsecured(无安全保护措施) wireless connection to surf the Net. What do you think about this topic? Listen to the following different views on it.
For a start, if someone is using your Internet service or downloading, this will affect your speed of access or download limit. Also, it’s bad for Internet service providers. They will suffer in the long run because fewer people will pay for an Internet service if they know they can get it for free. And finally, just imagine this: what if the person who is stealing your Internet connection is involved in an illegal activity? I think the police are totally right to arrest these criminals.
— by Sandra Wilkins
Basically, if the person who paid for the service still has everything they paid for, what’s the problem? It’s just like using the light from streetlamps to read your book, or watching someone else’s firework display. It’s not stealing.
Also, if you leave your wireless connection unsecured, then it is your own fault(过错) if someone else uses it. Just as you wouldn’t leave your front door unlocked, or your car door open, neither should you leave your wireless connection open. By leaving your wireless connection open, you are inviting people to use it. Securing your wireless connection is as easy as clicking a few settings on your router(路由器). And finally, haven’t the police got more important crimes to solve? They’re always saying how they haven’t got the manpower to solve real issues. But this is just ridiculous(荒谬的).
