Launch of World’s Thinnest Waterproof Speaker by MURATA
This newly developed piezoelectric speaker by Murata bears a thickness of only 0.9mm, qualifying it as the industry’s first ultra-thin speaker. The new speaker has a waterproof structure, satisfying the needs of mobile phone manufacturers with growing trend towards the waterproofing of mobile devices. Conventional dynamic speakers use waterproof sheets to cover sound output holes, however, the solution often resulted in degradation of sound quality as well as rise in overall cost.
The new speaker by Murata is an IPX7 grade waterproof piezoelectric speaker which does not require any waterproof sheet. Elimination of waterproofing sheet has contributed in cost reduction of the speaker. Furthermore, with elimination of magnets, there is no possibility of malfunctions caused by iron sand or electromagnetic effects on magnetic sensor. The new speaker applications will be in mobiles phones, mobile music players, digital still cameras, digital video camera, IC recorders, e-books to name a few. Murata is planning a monthly production of 1 million units, with a sample price of 250 JPY.
NEC Display Solutions launches latest eco-technology DLP projectors
NEC
Display, one of the leading manufacturers of quality imaging solutions,
today launches its latest mobile DLP projectors – NEC NP63 and NP43, successors
to the successful NP62 and NP41. Both models feature an autofocus function
and boast simple and rapid operation coupled with long lamp life. The low
weight and compact dimensions make these bright projectors ideal for mobile
use in corporate environments.
With a brightness of 3,000 and 2,300 ANSI lumen respectively and a contrast ratio of 1,600:1, the NP63 and NP43 deliver brilliant pictures in XGA resolution (1,024 x 768). Both projectors are real lightweights, coming in at just 1.7 kg. Thanks to automatic power-on, signal detection, automatic focus and auto keystone correction the projectors are extremely easy and quick to set-up in changing environments. Due to direct power off the NP43 and NP63 can be packed away instantly after use into the supplied soft case. The new lens cover enables the user to easily mute the projector during the presentation. The integrated carbon savings meter supports green corporate initiatives by encouraging users to operate the projectors in Eco mode and calculates the related CO2 savings. Eco mode lowers the operating cost by extending lamp life up to 3500 hours and reducing power consumption.
Trapping Sunlight With Silicon Nanowires
Solar
cells made from silicon are projected to be a prominent factor in future
renewable green energy equations, but so far the promise has far exceeded
the reality. While there are now silicon photovoltaics that can convert
sunlight into electricity at impressive 20 percent efficiencies, the cost
of this solar power is prohibitive for large-scale use. Researchers with
the Lawrence Berkeley National Laboratory (Berkeley Lab), however, are developing
a new approach that could substantially reduce these costs. The key to their
success is a better way of trapping sunlight.
NASA sets sights on inflatable space stations
Astronauts
may one day orbit the Earth in roomy balloons instead of cramped tin cans,
now that NASA has made inflatable space habitats a priority.
The White House announced a change in direction for NASA on 1 February. Instead of the planned crewed missions to the moon, the agency intends to pour money into research and development (New Scientist, 13 February 2010, p 8).
The outline listed technologies on NASA's wish list but provided few details. Now NASA has fleshed out its plans in a detailed budget proposal posted on its website on 22 February. One section notes that balloon-like habitats "can be larger, lighter, and potentially less expensive" than traditional ones made of rigid metal walls. They could be used as space stations, or eventually as moon bases. NASA may send inflatable structures to the International Space Station to test their mettle – including their ability to shield against space radiation.
The document also reveals that the agency plans to restart the NASA Institute for Advanced Concepts. Until it was closed by budget cutbacks in 2007, the institute funded research into potentially revolutionary technologies, including space elevators and antimatter harvesting. "Its cancellation was very short-sighted," says John Cramer of the University of Washington in Seattle.

A brief history of Technology
Man’s involvement with technology start from the very beginning. The hostile surroundings in which he evolved forced him to cultivate technology in order to improve his chances of survival. Perhaps, the first significant event in the history of technology was when he devised and made a stone hand axe.Around 500000 years ago man discovered the use of fire and hardened wood in it to make tools and weapons. Thousands of years later he made objects in horn, bone and wood.
New Water-based Material that Can replace Plastics
Scientists
at the University of Tokyo managed to create a brand new material
that is composed of 98 percent water. Researchers hope that their
latest invention could one day serve as an alternative for petroleum-based
plastics.
The latest invention of the Japanese researchers is called Aqua Material and besides water, the new material is also composed of clay mineral that is sometimes used in cosmetics, sodium polyacrylate, which is a chemical that is used in diapers to absorb moisture and an altered form of a medical compound known as G3-binder.
The strength of the new material is almost the same as the strength of silicon used in plastic surgery. If researchers use more clay they can make the material more rigid. When cut, the material "self-heals." In addition, the water-based invention can withstand temperature as high as 100 degrees Celsius.
Researchers consider their latest invention can be used in medicine, for example in treating internal injuries. It is worth mentioning that information on the new material was published in the British science journal Nature.
Nano-Robot Technology: Medical Perspective
A
nanorobot is a tiny machine designed to perform a specific task or
tasks repeatedly and with precision at nanoscale dimensions, that
is, dimensions of a few nanometers (nm) or less, where 1 nm = 10^-9
meter. Nanorobots have potential applications in the assembly and
maintenance of sophisticated systems. Nanorobots might function at
the atomic or molecular level to build devices, machines, or circuits,
a process known as molecular manufacturing. Nanorobots might also
produce copies of themselves to replace worn-out units, a process
called self-replication.
IBM To Build Next Generation Chips Using DNA
In future DNA wouldn’t just control human evolution but also computing evolution, if IBM succeeds to use DNA in development of next-generation microchips.
Scientists at IBM Research and the California Institute of Technology announced a scientific advancement that could be a major breakthrough in enabling the semiconductor industry to pack more power and speed into tiny computer chips, while making them more energy efficient and less expensive to manufacture.
Quantum Computing Closer To Reality
The ability to exploit the extraordinary properties
of quantum mechanics in novel applications, such as a new generation
of super-fast computers, seems to come closer following with recent
breakthroughs by an international team led by researchers from the
University of New South Wales.
In the two breakthroughs, written up in the international journals Nano Letters and Applied Physics Letters, researchers have for the first time demonstrated two ways to deliberately place an electron in a nano-sized device on a silicon chip.
