신기한 로봇의 세계

네발로 걷다가 포장된 길에서는 스케이트를 타는 로봇.



조금 느낌이 이상하긴 하지만 그래도 아주 잘 만들었다고 생각되는 4발달린 로봇.
평지, 자갈길, 흙탕길, 포장된 길, 비탈길 등을 이상없이 걸어가며 외부에서 밀거나해도 무게중심을 다시 잡고 절대 넘어지지 않는 로봇.

세계에서 가장 빠른 자동차, 세계최초 초음속 돌파 자동차

세계최초로 초음속으로 달린 자동차라고 합니다.
Rolls-Royce Spey 제트 엔진을 양쪽으로 장착한 이 자동차는 763.035mph, 시속으로 약1,149 km/h을 기록하였습니다. 영상으로 스피드를 느껴 보십시요.

세계에서 가장 빠른 오토바이(바이크) - Dodge 토마호크

세계에서 가장 빠른 바이크가 Dodge의 토마호크라고 하네요.

이어폰이 필요없는 개인용 음향시스템 구현(Personal Audio System without earphone)!!

KAIST 김양한 교수 "공공장소에서 나에게만 들리는 스피커 가능"

(서울=연합뉴스) 이주영 기자 = 스피커의 볼륨을 줄이지 않은 채 이어폰을 사용하지 않고 주변 사람들에게 피해도 주지 않으면서 음악을 혼자서만 즐기는 것이 가능할까?

국내 연구진이 스피커에서 나오는 음악 소리가 주변 사람들에게는 들리지 않고 사용자에게만 들리는 개인용 음향시스템을 구현하는 데 성공했다.

한국과학기술원(KAIST) 김양한 교수팀은 26일 컴퓨터 모니터에 소형 스피커 9개를 수평으로 배열, 사용자의 귀 주변에서만 소리가 들리게 하는 '음향집중형 개인용 음향시스템((sound focused personal audio system)'을 개발했다고 밝혔다.

이는 개인용 음향시스템의 실현 가능성을 처음으로 입증한 것으로 이를 발전시키면 공공장소에서 MP3플레이어나 PMP 등을 사용할 때 이어폰이나 헤드세트를 사용하지 않고도 사용자 혼자 음악을 즐기는 것이 가능해질 것으로 보인다.

연구팀은 이를 27일부터 미국 루이지애나주 뉴올리언스에서 열리는 미국음향학회(ASA) 학술회의에서 발표할 예정이며 ASA는 이 연구결과를 주목할 만한 내용으로 선정해 자료를 미리 공개했다.

사용자에게만 들리는 개인용 음향시스템은 음파가 충돌할 때 서로 간섭을 일으켜 소리가 더 커지거나 약해지는 현상을 이용한 것이다.

모니터에 일렬로 배치된 스피커 9개에서 나오는 음파들을 제어해 모니터 정면 방향의 지름 30㎝ 크기 원 영역(청취영역)에서는 소리가 커지는 보강간섭이 일어나게 하고 다른 공간에서는 소리가 약해지거나 없어지는 상쇄간섭이 일어나도록 한 것이다.

9개의 스피커에서는 800Hz에서부터 5kHz까지 주파수가 다른 음파가 나오며 이들 음파들은 정면 방향의 사람 얼굴 크기 정도 공간에서는 상호 보강간섭에 의해 소리가 커지고 이곳을 벗어난 곳에서는 상쇄간섭을 일어나 소리가 작아지거나 없어진다.

연구진이 이 시스템을 만들어 모니터에서 40㎝ 떨어진 곳에서 소리의 크기를 측정한 결과 청취영역에서 들리는 소리가 그 밖의 공간에서 들리는 소리보다 20㏈ 이상 더 큰 것으로 나타났다.

김 교수는 "미국 마이크로소프트는 올해 초 10대 미래과제 중 하나로 개인용 음향시스템 구현을 꼽은 바 있다"며 "이 결과는 개인용 음향시스템을 구현하는 것이 현실적으로 가능하다는 것을 보여주는 것"이라고 말했다.

그는 이어 "이 기술을 발전시키면 궁극에는 휴대전화나 컴퓨터 모니터, 혹은 TV를 볼 때 다른 사람을 방해하지 않기 위해 이어폰을 사용하는 불편이 해결할 수 있게 될 것"이라며 "하지만 이런 음향시스템을 실용화하려면 성능을 평가할 수 있는 지표 선정이나 다양한 목적에 맞는 음향시스템 모델 개발 등 풀어야 할 과제들이 아직 많다"고 덧붙였다.

It's dumb to test the Amazon Kindle by sitting at a desk, pressing a lot of buttons. The real judgment as to its usefulness has to come after experiencing it throughout the week in three key real-life reading scenarios:

• In the bedroom

• On an airplane

• Atop the porcelain throne (yes, I'm talking about the toilet)

Join us as we take you where we don't like to take too many strangers, and experience the real-life Kindle review:

I understand the Kindle. Book reading is always a one-on-one activity, and there is more or less only one way to experience a book—from a rectangular object in your hand. An e-book reader that's PC-free, connected directly to the book source, is even smarter than an MP3 player or phone that's connected to a music store, because music ends up all over the place, while books will always stay in your lap.

People bitch about a lack of Wi-Fi, but as a fan of wide-area wireless, I think Sprint's EV-DO was a good way to go, because it's available in more places. And as far as the lack of backlight, I am inclined to believe the messaging from both Amazon and Sony, that E-Ink is easier on the eyes than anything backlit, and that long battery life is more important. I used the Kindle regularly without charging for four days straight before it completely crapped out just this morning.

As for the criticism about document and e-book format compatibility, I suspect these problems will work themselves out over time, as the Kindle's Linux platform is surely easy to enhance through software. At any rate, you already know many of the issues, so there's no point rehashing them here, especially when much of it is a matter of personal preference.

No, none of these theoretical concerns were in my mind as I read using the Kindle this week, but that's not to say I didn't uncover some issues. Here's what I discovered this week while reading a book on Kindle—Heat by Bill Buford— that I was already halfway through in its old-world hardcover paper form:

In Bed:

• Next Page buttons on both sides mean tremendous comfort in bed. No matter which hand you are holding the Kindle in, you can easily turn the page, and if you have it sitting on the bed next to you, you can even tap the large button on the right with a finger or your elbow.

• Since it's much larger than a hardcover or even a trade paperback, you can hold it without tiring out your arm, or needing to use your leg to prop it up.

• Normally when reading in bed, you have to shift positions when you turn the page, especially when at the beginning or end of a large book. Since the Kindle only displays one page at a time, and doesn't have a shifting weight of pages from one side to the other, you can pick a position and stick to it.

• I have a lamp next to my bed for reading old-school printed books; it works just as well with Kindle.

In the Air:

• EV-DO isn't available everywhere, or even at all airports. The one I flew out of only provided a paltry 1X signal, and it took me about five minutes to download the current issue of The Atlantic Monthly.

• Speaking of The Atlantic, text-heavy weeklies and monthlies really are the target. Newspapers are a problem, because the editions that appear on Kindle are already outdated by their own websites, so newshounds would get frustrated. The lineup of magazines needs to grow, though. I won't be happy until The Economist and The New Yorker appear on the menu. (I may come from the Great Red State of Indiana, but I prefer my current events smart and a little left-leaning. But while we're at it, Amazon, a Guns N' Ammo Kindle Edition might be nice too.)

• Once aboard, FAA regulation required that I not use the Kindle at takeoff and landing. Though obvious, this pissed me off because that's when I always read on planes, before iPod time kicks in and I have the option of a movie.

• There's a handy switch to shut off the cellular data modem, and prove to the flight attendants you're no rule-breaker.

• The onboard Oxford New American Dictionary is good but not great with proper nouns. It picked up "Romanesque" but did not get "Florentine," for instance. And Wikipedia, which would have more elaborate data on both, is of no use when you're airborne.

• Private reading lights have been part of the airplane experience since time immemorial. No backlighting on e-book readers means this glorious tradition will continue.

On the Toilet:

• Friction rubber grip makes it okay to set down on the side of your sink or back of toilet without it slipping. We have a porcelain pedestal sink in one bathroom that anything without a grip would slide off of—and smash on the floor.

• Buttons on both sides of the Kindle mean that it's sometimes hard to grip it securely and not press a button. I were to hypothetically make a mad dash to the toilet, Kindle in hand, I would risk flipping a bunch of pages on the way and losing my place.

Other usage discoveries:

• As I mentioned, the battery lasted four full days of regular use, mostly with the EV-DO switch turned on. (It probably would have run much longer if I had left it off.) When your battery gets low, you get the error message below, but shutting down EV-DO that late in the game does nothing to conserve battery life, which died 5 minutes after I saw this. Charging is quick though—juice it for 15 or 20 minutes and it's good to go for a while.

• I never turned the thing off, either: when you leave it alone for a few minutes, it turns to a keylock screen with a pretty picture or a promotional tip (see gallery below—I've shot 8 so far, but there are tons of 'em). You click and hold the Alt and font-size buttons to release it.
galleryPost('KindleScreenSavers', 6, '');

• I will never understand the magical technology behind the shiny LCD bar on the right. It is sooo pretty I sometimes do stuff just to watch it jump around. Very unique in this copycat-heavy CE universe.

• The leather case is good for protecting and carrying around without hitting buttons (see "On the Toilet"), but it is totally lame when you are trying to read. Slip it out and hide the case until you are ready to move again.

• The Highlight clipping tool is too primitive to be cool. You can only highlight a line at a time, so your clippings, particularly when viewed by themselves, look ugly and confusing. Anything you highlight is automatically saved in My Clippings, where all of your Clippings, from all publications, are lumped together.

• In natural settings, I never used the web browser. I surf the web a-plenty in my daily life, and while I'm reading, I'm just not thinking about dot coms.

• The keyboard does have a bit of a lag, as we reported, but that's not too problematic. My biggest problem is the spacebar, hidden on the left side. Little known trivia: As it turns out, I SPACE with my right hand.

• Footnotes are weird. I was reading a David Foster Wallace piece that, like most of his work, was riddled with footnotes, and each time I had to click it to see the note, which could get annoying. Same goes for Colbert's book I Am America.

• My wife likes it. OK, so you weren't curious about that, maybe, but she's a voracious reader and she generally turns her nose up at most of the gadgets that arrives at our doorstep. With the Kindle, though, she got excited. She picked it up and started reading the Atlantic Monthly, saying how "amazing" it was that Amazon got the magazine's formatting right, and how pleasant the E-Ink was to read.

• In the end, looks mattered least of all. Even though my wife thinks it looks like a "medical device," it was not a turn off. I think people underestimate its wedgey coolness, while overestimating the impact that would have. Bezos said you don't look at the thing, you look at the book within—maybe he was anticipating a hazing from the Style Police, but I think he's right. I just read my damn book.

My verdict is that a connected e-book reader was what the world needed, and as long as Amazon's library expands to encompass every book I want to read, I see no reason why I should be upset that I have to buy it from them. Yes, $399 is expensive, but that's likely to drop, and the more market-resistant $9.99 book price hits a Jobsian sweet spot.

Having lived with the Kindle, I can say that it serves most of my immediate reading needs. As a guy who enjoys amassing a vast library of books and displaying them in bookcases, I am a little frightened of the future, but inevitability is the name of the game, and fear of change isn't a good enough excuse. Will I continue to buy books or will I jump into Amazon book buying mode? That remains to be seen, but you, o early adopter, should not share my fears. The Kindle is a quality invention, and I can see why the first batch sold out so fast.
