Timed Morning Bowel Movements


You may be wondering what this glass-alarm has to do with your morning bowel routine. First off, a warm glass of water as soon as you wake up is the perfect way to start your day. It helps in detoxing your body and gets your bowels moving. So there! now to establish relation with the “Revive Glass”…it’s an alarm clock that holds a glass of water. Half hour before your alarm is to go off, the base starts warming up the water, so that you drink it warm enough. The alarm shuts off only when you pick up the glass of water. I totally dig the time being read thru water! Looks awesome!

Unmanned solar plane smashes records

London, England (CNN) -- An unmanned solar aircraft has smashed the world record for continuous flight.

The "Zephyr" plane, developed by UK defense technology company, QinetiQ, took off from the U.S. Army's Yuma Proving Ground in Arizona on July 9. Seven days on, it was still flying high.

Zephyr program director, Jon Saltmarsh told CNN: "It's extremely exciting. What we now have is an eternal plane. It has the same amount of fuel at the start of one day as it does at the start of another."

The aircraft has already doubled its own unofficial record of over 82 hours and smashed the previous world record for unmanned flight of 30 hours and 24 minutes, set in 2001 by U.S. aerospace company, Northrop Grumman's RQ-4A Global I.

The Zephyr project was conceived in 2001 and secured funding from the UK's Ministry of Defense (MOD) three years later. After several prototypes, Saltmarsh believes QinetiQ has now created an aircraft that demonstrates genuine military utility.

"It has the persistence to stay up there for long periods of time and it carries payloads that are doing things that the military will find useful."

Saltmarsh says its key role will be in aiding communications.

"Sitting at 60,000 feet it's ideal for getting a line of sight between two people in different valleys," Saltmarsh said. "But it could also carry surveillance payloads."

QinetiQ also says it will save the military money, performing many of the tasks currently carried out by manned aircraft.

Weighing just 53 kilograms (117 pounds), the plane has a wingspan of 22.5 meters (74 feet) and a wing area of around 30 square meters (323 square feet), the top side of which is covered in solar panels thinner than a sheet of paper.

The panels are rigged up to lithium-sulphur batteries which power the plane at night.

QinetiQ began building the latest Zephyr model 18 months ago and hope to start full scale military trials a year from now.

The company says that Zephyr will also find a civilian use helping communications in disaster relief situations, as well as forest fire monitoring.

"You can sit above a fire, with heat sensor technology and identify hotspots very quickly," Saltmarsh said.

Zephyr shows no sign of running out of power anytime soon, and Saltmarsh is hopeful it will stay in the air for another seven days, when the plane will finally return to Earth.

Scientists Crack Mona Lisa's Secret By X-Raying Her

Scientists Crack Mona Lisa's Secret By X-Raying HerApparently, everyone has long been baffled by how Leonardo da Vinci created such subtle shadows and light on the Mona Lisa. So much so that scientists X-rayed the painting to discover his technique.

Scientists have discovered that da Vinci used a well known renaissance painting technique known as sfumato. For the non art historians among us, Sfumato is the mixing of thin layers of pigment, glaze, and oil to create lifelike shadows. The difference with Da Vinci was just how intricate his layers were. Apparently, Da Vinci used 30 layers of paint that amazingly only added 40 micromemters of paint—that's half the width of a human hair.

The X-ray fluorescence spectrometry used was noninvasive and allowed scientists to see each layer of paint. It's a tool that's so precise that it can determine the mix of pigments used by an artist. Philippe Walter, the man who X-rayed Mona Lisa:

In the case of "Mona Lisa", Leonardo da Vinci used a mixture of maybe oil and resins, a binder with a very low amount of pigments. And with this mixture it was possible to create a very impressive aspect of the painting - a realistic, like a 3-D painting."

But even with that fancy x-ray, scientists still say that finding brushstrokes on the Mona Lisa is impossible. No word on how hard it is to find hidden messages though. [CNN]

Minority Report Intelligent Digital Billboards Are Real

Minority Report Intelligent Digital Billboards Are RealYou remember those billboards in Minority Report, the ones that personalize what they display depending on who stands in front of it. Tokyo is rolling out digital billboards that do the same thing.

In Minority Report, the billboards worked like this:

In Tokyo, the billboards are outfitted with cameras that can determine the gender and age group of any passerby who takes a look at them. Even if you just glance at them, the digital billboards only need a second to figure out if you're a young girl who would like Hello Kitty or an old man who would want a young girl. They promise they're not recording anyone but they are collecting data to better target those old, so 2009 print billboards.

Welcome to the future where advertisement is disguised as technology. [SmartPlanet]

Recycled Island: A Colorful Paradise Made From Garbage

Recycled Island: A Colorful Paradise Made From GarbageThe resourceful Dutch want to turn the Pacific Garbage Patch into a tropical destination. The idea is to recycle the plastic waste floating in our oceans into building materials for an habitable, self-sustaining island.

Recycled Island would be about the size of Hawaii's biggest island and would be located in between Hawaii and San Francisco. The lofty project's main goals are to recycle the plastic floating in the ocean, establish a stable and seaworthy island and make the island self-sufficient with its own sustainable foods and energy sources. So we're talking houses made from plastic, fertilizable soil made from seaweed and human manure, and electricity coming from solar, wave, and wind power.

The concept of Recycled Island is admittedly far-fetched but any time you put together recycled plastics and human manure on an island, I'm interested. Plus, the Pacific Garbage Patch isn't going to disappear on its own; maybe this concept will drive skeptics to figure out a more practical solution. [Recycled Island via PopSci]

Dyson Air Multiplier 空氣倍增器
Cool~~~~~~



 
 
使用者把手伸進機器的烘乾槽以後,透過感應裝置,機器便吸收周圍空氣,並排放出符合美國國家衛生基金會NSF標準的乾淨空氣,大約八秒鐘的時間將使用者手上的水吹乾。 
  
 
產品實物就是這模樣,尚未正式引進台灣。


戴森研發團隊從烘手機可吸取周圍的大量空氣的功能,開始思索如何將這原理與功能再擴大應用,經過4年研發測試,終於開發扇葉的空氣推進裝置。
 
  
 
Dyson研發出比原本馬達還要嬌小,卻能產生更大動力的微型數位馬達。空氣有吸就有放,大家都明白這是一體兩面,所以dyson既然能研發出具有強大吸力的吸塵器,要做出一個具有強送風力的機器自然不是問題。


比照吸塵器和烘手機的動力結構,將這個微型數位馬達作為空氣倍增器的動力來源。
 
  
 

空氣倍增器的側剖面圖,請留意環的剖面結構。
 
 

當然不是隨便做個環就可以,這個運用空氣動力學製造出類似飛機機翼的氣旋翼環,在倍增空氣量上扮演了很重要的角色。

無扇葉電扇送風的原理?
一個寬僅1.3公釐的周邊沿狹縫。


當空氣通過圓圈時,速度提高至每小時35公里。



藉由強大的數位馬達抽風,以及與氣旋翼環的增幅效果,使得運動的空氣量增加15倍。

產生的氣流也比一般電扇的風更平穩。



因此使用者不用擔心風量,作為家電,它產生的風不會更多,品質卻更好,送爽效果一流。



由於它並未配置負責『切割』空氣的扇葉,運轉時沒有葉片轉個不停;視覺上不會令人感到煩躁。而且沒有扇葉就不用擔心好奇的孩童手指受傷,也不用拆開清理扇葉上的灰塵。
 
 

 
相信很多朋友從報章雜誌上,看到這張圖片,
新聞的內容表示某家科技公司生產了一種不需要葉片的電風扇。


這就是英國的Dyson公司所研發的Air Multiplier,中文直譯為空氣倍增器。
 
 

這款空氣倍增器看起來就像一個巨大的戒指,我個人看這圖覺得很像可穿越異次元時空的Star Gate。

只有看到這類商品的問世,才覺得總算有接近2010年的未來感呀,
小時候總以為到了2010年,人類就會在外太空生活,可以到月面城市旅行了呀。


環內確實是空無一物,運轉時也不會突然變形伸出葉片。

這款新家電顛覆了以往的常識,一個不需要葉片的風扇。

或者大家可以拋開風扇這的概念,直接把它當作送風器會更適當。

底座的控制部件,最左邊是開關,中間是風量調整,最右邊雙箭頭符號按鍵開關,啟動後就是一般電風扇所具備的左右擺動功能。

此外還可以調整送風上下方向。
發表展出以來,獲得各界好評,目前已在英國哈洛斯等高檔百貨公司發售,定價199英鎊(約台幣1萬元)。

James Dyson表示, 他是在研發「Air Blade 空氣葉片烘手 機」時,突發設計無扇葉電扇的奇想。

Grow-your-own approach to wiring 3D chips

When the island of Manhattan became too crowded, architects responded by building skyscrapers. The increasing density of components on "flat" computer chips is encouraging similar ideas, building upwards to create three-dimensional chips. But moving from flat interconnecting wires to 3D ones to link up different "storeys" has proved a tricky business – until now.

Instead of soldering prefabricated wires in place, as is traditionally done to connect two parts of a chip, Min-Feng Yu and Jie Hu at the University of Illinois at Urbana-Champaign have developed a technique to grow tiny 3D wires in situ which are tailor-made for their location.

Yu and Hu's technique is a modified form of electroplating, in which an electric current is used to coat a conductive surface with a thin layer of metal, deposited from a liquid electrolyte. Such a technique theoretically offers a way to directly "write" metal wires onto a surface.

Liquid bridge
But using such electrodeposition to build tiny wires, rather than indiscriminately plating an entire surface, is challenging. One option is to hold the electrolyte in a pipette that's then brought near to the conductive surface. Then, when an electrical potential is applied between the two, a thin "liquid bridge" is established. Copper or platinum particles in the electrolyte are attracted to the surface, creating a small metallic blob.

Yu and Hu realised that because the metallic blob continues to grow away from the surface and along the liquid bridge as long as the electrical potential is applied, the method offers a way to grow 3D wires that extend above the surface instead of just "two-dimensional" ones that run along it.

The trick is to carefully synchronise the speed with which the micropipette is withdrawn from the surface so that it matches the growth rate of the metal blob. When done correctly, the micropipette leaves a solid, 3D metallic structure in its wake. By moving the pipette parallel to the surface, instead of just vertically away from it, it is possible to create intricate 3D structures (see image). Such metallic bridges could link different parts of a conductive surface, or link two conductive surfaces or components at different heights on a 3D chip.

With a small enough pipette, the researchers have grown freestanding interconnects more than 80 micrometres long but just 100 nanometres wide. "That's one order of magnitude smaller in diameter than is possible in current practice," says Yu.

Take the heat
These interconnects can withstand current densities a million times higher than those that will burn out a traditionally soldered interconnect, because the electrodeposited metal forms a much stronger bond with the surface than a soldered joint.

The work provides an "elegant solution" to the problem of growing intricately shaped 3D wires in chip manufacture, says Peter Searson of Johns Hopkins University in Baltimore, Maryland. "It is likely to be an important new tool for the fabrication of three dimensional architectures at the micron scale."

Yu and Hu now hope to shrink the diameter of their wires by yet another order of magnitude, while also scaling up the technique to create a quick, industrially compatible process. "Instead of fabricating wires one by one, we will try to find a way to fabricate them in an array fashion," says Yu.

Silicon chip speed record broken on a lead-coated track

A "RACETRACK" capable of shuttling electrons around at high speed has set a new record for silicon chips, the cornerstone of computing.

Electrical resistance imposes a strict speed limit on electrons travelling through silicon. To break this limit, computer scientists are considering replacing silicon with carbon, as atom-thick sheets of carbon, or graphene, conduct electricity better than any other substance at room temperature.

Graphene owes this property to an unusual interaction between its hexagonal lattice structure and the electronic structure of its atoms. This effectively brings the mass of its free electrons down to zero. That apparent weightlessness allows them to zip across graphene like photons, reaching speeds of up to 0.003 of the speed of light in a vacuum.

The snag is that graphene is difficult to make in bulk. Now Han Woong Yeom and his team at the Pohang University of Science and Technology in South Korea believe they can mimic its conductivity in silicon. They have clocked electrons travelling 20 times faster than usual in their silicon chips.

Yeom's team added an atom-thick layer of lead to the surface of a silicon block. Because the lead layer is so thin, the arrangement of its atoms is influenced by the silicon atoms underneath. The team suspected that the lead's electrons would, in turn, influence the electronic structure of the silicon at the interface.

To investigate, they fired high-energy photons at the material to knock electrons out of it, and measured their momentum and energy. By subtracting the energy the photons contributed to the displaced electrons, they calculated that some of the electrons at the silicon-lead interface had an apparent mass 1/20th of that of the electrons in typical silicon chips (Physical Review Letters, DOI: 10.1103/PhysRevLett.104.246803). "This indicates the possibility of 20-times-faster electrons," says Yeom.

Adding a thin layer of lead to a silicon semiconductor could speed up the chip by 20 times
That's still just one-third of the speed of electrons in graphene, but in principle the electron mass can be further reduced - and their speed increased - if different metals are used to coat the silicon, he adds.

"It's fantastic progress," says Zahid Hasan of Princeton University. Speedy silicon could easily outrace graphene to the shelves as the manufacturing infrastructure is already in place, Hasan says.

新一代銀行卡自帶迷你鍵盤和屏幕 


 
顯示螢幕鍵盤全新銀行卡與傳統的卡差不多大,背面多了迷你鍵盤和顯示螢幕。
據英國“每日郵報”17日報導,國際知名信用卡品牌簽證即將發行新一代銀行卡,它可以使用戶在每次網上交易時獲得一個新的支付密碼,從而大大提高網路購物的安全性,不再讓線上詐騙有可乘之機。

防駭客程式盜取
這種全新的銀行卡與傳統的信用卡幾乎差不多大,只是在背面多了一個包含12鍵的迷你鍵盤和一個迷你顯示螢幕。你可不要小看這項設計,它是用來生成可以不斷變化的新支付密碼。每次網上結算的時候,用戶都需要在迷你鍵盤上先輸入固定密碼,然後迷你顯示螢幕上會顯示一個專門用於本次交易的一次性支付密碼(由字母和數字組成) 。接下來用戶再輸入這個新密碼方能完成結算。
維薩公司介紹說,這個新功能叫做“簽證密保”,主要用於提高銀行卡在網購物時的安全性。因為網路購物與在實體店鋪購物刷卡需要輸入密碼和個人簽名不一樣,它的支付程序更加簡單,安全係數也因此大大降低。
之前,一些騙子通過網路木馬等客程盜取用戶的銀行卡賬號和相關個人資料訊息,然後就能輕鬆完成網路支付等虛擬交易,而銀行方面很難確定付款者到底是不是真正的持卡人。在英國,每年因銀行卡賬號,用戶資料被盜所引發的網路欺詐案件涉及的金額高達 2.66億英鎊。

裝有電池用3年
如今,有了“簽證密保”,駭客們就不能再用慣用伎倆作案了。即便有人盜取了用戶某次網路支付中使用的密碼也毫無意義,因為該密碼在使用一次後就自動作廢,下一次網路購物需要完全不同的新密碼。
維薩歐洲分部創新部門一位負責人表示,“這是簽證的獨家創新,目的是要讓用戶在網路購物中享受到和實體購物一樣的安全性能。”
據悉,“簽證密保”已經在英國,意大利,以色列,土耳其,瑞士和德國進行了試驗,絕大多數人在現有的銀行卡到期時即可更換這種新一代銀行卡。新的銀行卡裝有迷你電池,大約 3年更換一次。

如何操作
每次網路購物或登錄網上銀行時,持卡人需先通過按卡上內置的“認證”鍵來啟動發卡行授權過程,獲得授權後,在鍵盤上輸入自己的固定密碼,之後,顯示螢幕上會顯示一個一次性使用的網路支付新密碼(包含字母和數字,由銀行提供)。有了這個密碼,網路支付才能完成。

Washing Machine Goes Wall Mount

As promised, I’m here with the details on the Dismount Washer. It’s a concept that looks at space saving and hygiene at one go. The way it works is like this, you have your own personal tub for your laundry that can be mounted on an “energy stick”. Using high-pressure steam as its source for cleaning, the washers does its job, and gives a fresh batch of washed clothes. A touchscreen display is integrated for easy navigation and menus. Ideal setup for those who prefer using Laundromats or don’t have space for a washing machine at home.
