A recent decision by Japan’s Toshiba Corp to exit certain consumer
laptop markets is likely to benefit Taiwan’s Asustek Computer Inc
because of their similar product positions, brokerage Morgan Stanley
said on Sunday.
Following Sony’s disposal of its Vaio PC business
and Samsung’s scaling down of its notebook business, Toshiba announced
on Thursday that it would accelerate the restructuring of its PC
business and withdraw from certain consumer markets.
The Japanese
electronics conglomerate said it would also cut 900 jobs during the
current fiscal year, which was expected to save the company more than
￥20 billion (US$184 million) in fixed costs compared with the previous
year.
“We see Asustek as the major beneficiary if Toshiba
withdraws from some consumer markets [because] both have consumer
products in similar price ranges,” Grace Chen, a Morgan Stanley
analyst in Taipei, said in a note to clients.
In comparison, Lenovo Group and Acer Inc are targeting the lower-end consumer notebook segment, she said.
Citing
data from research firm IDC, Chen said Toshiba’s PC business covers
mainly notebooks, which declined by an annual 15 percent last year to 14
million units, holding an 8 percent share of the global market.
Asustek, meanwhile, shipped 19 million notebooks last year, she added.
“Asustek’s
third-quarter notebook shipments are tracking slightly ahead of our
forecast and we expect its fourth-quarter shipments to outperform its
peers, as it will launch new products,” Chen said.
Acer founder
Stan Shih on sunday said at a press briefing that Toshiba’s
restructuring plan is a “normal” phenomenon in the PC industry that
allows PC companies to reflect on their decisions and learn more about
the industry’s dynamics.
The PC industry needs to change its role after more than 30 years in
existence and it also needs new strategies to deal with the shrinking
market, Shih said on the sidelines of a awards ceremony for an Acer
comic competition, a promotional event for its cloud services.
Gadget converts sound waves from speech into five volts of energy for your mobile.
As the class Governor of my department at Yaba college Of technology,
It seems phone batteries always die at the same moment you need to make
an important call like calling a Lecturer , before class or after
class.
But while shouting at your mobile in frustration might seem
pointless, a new gadget could soon mean your screams won’t be in vain.
Researchers in London have created a new technology that uses sound,
such as chants at a football ground or chatter in a coffee shop, to
charge up mobile phones.
Their prototype device, which is about the size of a mobile phone,
uses zinc oxide to convert vibrations caused by sound into electricity.
The invention was inspired by previous research at Queen Mary
University of London (QMUL), which found playing pop and rock music
improved the performance of solar cells.
This was because the sound vibrations triggered the movement of
material in the solar cell that caused it to improve efficiency by up to
40 per cent.
Developing this research further, Nokia worked with the QMUL team to
create an energy-harvesting prototype that could be used to charge a
mobile phone using everyday background noise.

Nokia worked with the QMUL team to create

phone using everyday background noise. Pictured here is the zinc oxide
used in the device.
The team used the key properties of zinc oxide, a material that when
squashed or stretched creates a voltage by converting energy from motion
into electrical energy, in the form of nanorods.
The nanorods can be coated onto various surfaces in different locations making the energy harvesting versatile.
When this surface is squashed or stretched, the nanorods then generate a high voltage.
The nanorods respond to vibration and movement created by everyday sound, such as our voices.
Electrical contacts on both sides of the rods are then used to harvest the voltage to charge a phone.
In order to make it possible to produce these nanogenerators at
scale, the scientists found innovative ways to cut costs in the
production process.
Firstly, they developed a process whereby they could spray on the
nanorod chemicals – almost like nanorod graffiti – to cover a plastic
sheet in a layer of zinc oxide.
When put into a mixture of chemicals and heated to just 90°C, the nanorods grew all over the surface of the sheet.
Secondly, gold is traditionally used as an electrical contact, but
the team were able to produce a method of using cheap and cheerful
aluminium foil instead.
The final device is the same size as a Nokia Lumia 925 and generates five volts, which is enough to charge a phone.
‘Being able to keep mobile devices working for longer, or do away
with batteries completely by tapping into the stray energy that is all
around us is an exciting concept,’ said Dr Joe Briscoe from QMUL.

mobile phone using everyday background noise.
Nokia worked with the QMUL team to create
an energy-harvesting prototype that could be used to charge a mobile
phone using everyday background noise. Pictured here is the zinc oxide
used in the device.
The team used the key properties of zinc oxide, a material that when
squashed or stretched creates a voltage by converting energy from motion
into electrical energy, in the form of nanorods.
The nanorods can be coated onto various surfaces in different locations making the energy harvesting versatile.
When this surface is squashed or stretched, the nanorods then generate a high voltage.
The nanorods respond to vibration and movement created by everyday sound, such as our voices.
Electrical contacts on both sides of the rods are then used to harvest the voltage to charge a phone.
In order to make it possible to produce these nanogenerators at
scale, the scientists found innovative ways to cut costs in the
production process.
Firstly, they developed a process whereby they could spray on the
nanorod chemicals – almost like nanorod graffiti – to cover a plastic
sheet in a layer of zinc oxide.
When put into a mixture of chemicals and heated to just 90°C, the nanorods grew all over the surface of the sheet.
Secondly, gold is traditionally used as an electrical contact, but
the team were able to produce a method of using cheap and cheerful
aluminium foil instead.
The final device is the same size as a Nokia Lumia 925 and generates five volts, which is enough to charge a phone.
‘Being able to keep mobile devices working for longer, or do away
with batteries completely by tapping into the stray energy that is all
around us is an exciting concept,’ said Dr Joe Briscoe from QMUL.

Gadget converts sound waves from speech into five volts of energy for your mobile.
As the class Governor of my department at Yaba college Of technology,
It seems phone batteries always die at the same moment you need to make
an important call like calling a Lecturer , before class or after
class.
But while shouting at your mobile in frustration might seem
pointless, a new gadget could soon mean your screams won’t be in vain.
Researchers in London have created a new technology that uses sound,
such as chants at a football ground or chatter in a coffee shop, to
charge up mobile phones.
Their prototype device, which is about the size of a mobile phone,
uses zinc oxide to convert vibrations caused by sound into electricity.
The invention was inspired by previous research at Queen Mary
University of London (QMUL), which found playing pop and rock music
improved the performance of solar cells.
This was because the sound vibrations triggered the movement of
material in the solar cell that caused it to improve efficiency by up to
40 per cent.
Developing this research further, Nokia worked with the QMUL team to
create an energy-harvesting prototype that could be used to charge a
mobile phone using everyday background noise.
