Didn't I make you feel
Like you were the only man
And didn't I give you everything
That a woman possibly can
Each time I tell myself I think I've had enough
Well I'm gonna show you baby that a woman can be tough
So come on, come on, come on and
Take it
Take another little piece of my heart now baby
I know you will
Break it
Break another little piece of my heart now baby
'Cause you know you got it if it makes you feel good, so good
You're out on the street lookin' good
Baby deep down in your heart you know that it ain't right
No you'll never hear me cryin'
You know I cry all the time
Each time I tell myself that I can't stand the pain
You hold me in your arms and I start singin' once again
So come on, come on, come on and
Take it
Take another little piece of my heart now baby
I know you will
Break it
Break another little piece of my heart now baby
'Cause you know you got it if it makes you feel good, so good
Each time I tell myself that I can't stand the pain
You hold me in your arms and I start singin' once again
So come on, come on, come on
Take it
Take another little piece of my heart now baby
I know you will
Break it
Break another little piece of my heart now baby
'Cause you know you got it if it makes you feel good, so good
Bluetooth is a specification for a radio solution that is small form-factor, low-cost, and low power,that provides seamless wireless connectivity between notebook computers, cellular phones and other portable handheld devices. The Bluetooth Special Interest Group (SIG) is comprised of leaders in the telecommunications, computing, and networking industries who are driving the development of
the technology to bring it to market. The Bluetooth SIG includes promoter companies such as 3Com, Ericsson, IBM, Intel, Lucent, Microsoft, Motorola, Nokia and Toshiba, and over 2000 other adopter/associate member companies.
Bluetooth operates in the license-free 2.4GHz ISM band at a link range of 10 meters. With improved transmission power and receiving sensitivity the range can be increased up to 100 meters. Bluetooth is expected to be a standard feature on the next generation Smart Phones, PDAs and computers.
The wireless Personal Area Networking (PAN) of mobile devices including notebooks, PDAs, Smart Phones, Web-pads, headsets, and digital cameras is driving Bluetooth development. PAN provides synchronization of a notebook and a PDA, file transfer between a notebook and a digital camera, and voice communications between a Smart Phone and a cordless headset.
BLUETOOTH MARKET
Named after the 10th century Danish King, Harold Bluetooth who unified Scandinavia, Bluetooth technology is the worldwide industry standard that provides point to multipoint, radio frequency (RF) connectivity. Today 2 the Special Interest Group (SIG) comprises of more than 2000 companies in various industries including
computing, telecommunications, networking, automotive, consumer electronics, military, medical, industrial and others. The technology aims to offer easy, quick, reliable and secure device-to-device connectivity at a short range.
Specification 1.0 and 1.0b were released in 5/99 and 12/99 respectively. Various chips, modules, and add-on products have been announced.

Summary of Announced Bluetooth Products
Ericsson was the first company to introduce a Bluetooth module product based on its own RF and a VLSI/Philips baseband chip in early 2000. Since then, SiliconWave has introduced their RF and baseband solution, Philips has announced the TrueBlue module based on the Philips transceiver and basedband. Lucent, Philips, Qualcomm and STMicro have been reported to license the Bluetooth IP from Ericsson. Other vendors
like CSR, OKI, and Infineon have also announced their respective Bluetooth chip set solutions.
These first generation Bluetooth silicon solutions are based on three architectures: the ASIC plus RF chip (Ericsson), the DSP plus RF chip (Motorola and National), or a single chip CMOS implementing both RF and baseband (CSR). Moreover, three different silicon technologies are used: BiCMOS (Ericsson), CMOS (OKI and CSR), and Silicon-on-Insulator (SiliconWave).
SmartPhones are one of the first devices to incorporate Bluetooth. Ericsson and Motorola have announced their respective cell phone products, the Ericsson R520 and the Timeport 270. Motorola has also introduced its Bluetooth PC cards and USB devices through its Digianswer group. In August, Intel announced its Ambler
module technology for notebook support. Palm has demonstrated Bluetooth-enabled handheld computers at Cebit 2000. Handspring has shown a Bluetooth Springboard solution made by Widcomm. Last but not least, Toshiba has started shipping their Bluetooth PC card for its notebook products.
BLUETOOTH TECHNOLOGY
A typical implementation of Bluetooth includes the RF, baseband, HCI interface, and host stack software.
RF
Bluetooth operates in the license-free 2.4-2.4835GHz ISM band by frequency hopping at a rate of 1600 hops/s within 79 1MHz channels. Japan, France and Spain have a smaller band but these issues are being resolved.
Bluetooth supports 10-meter range and 1Mbps rate and a 100-meter range with improved transmission power and receiving sensitivity.
BASEBAND
A wireless PAN, more often referred to as a Piconet, provides the cable replacement for connectivity among various devices such as a notebook PC to a cell phone, a cell phone to a headset, a PDA to a notebook, a cell phone to PSTN, a notebook/PDA to Internet and LAN, and other ad-hoc networking applications. Multiple devices (256 parked, 8 active) can participate in a Piconet.
Bluetooth Internet Access Point
We believe that the following features are important for a Bluetooth Internet Access Point based on LAP:
· Standards Compatibility: Supports standard Bluetooth-enabled devices including Smart Phones without
software modifications
· Extended Range and Sensitivity: Increased from 10 meters to 40-100 meters of range while conforming to
the Bluetooth specification
· Seamless Internet Connectivity: Provides seamless multiple access for standard Internet content
· Low Cost Implementation: Targets mass market adoption

Nuclear power is still unsafe and cannot help the UK meet its pollution targets. Here's the low-down on an energy a former Environment Minister says we need 'like a hole in the head'.
Expensive
Dangerous waste
Environmentally unfriendly
Security threat
Real alternatives
Expensive
Costs more than wind - In 2002 the Cabinet Office estimated that nuclear could cost over 40% more per kWh than on/off-shore wind.
Waste of money - Construction costs are large and unpredictable with delays causing greater losses. Windfarm costs are known, smaller and falling.
Hits taxpayers - Disposal of existing waste will cost around £56 billion. More reactors mean more waste, with no guarantee that costs won't be passed on to the public.
Dangerous waste
Highly radioactive - Nuclear waste can remain dangerous for tens of thousands of years.
Deadly inheritance - No one has yet demonstrated a safe way of disposing of it .
Accidents do happen - Leaks and near misses cannot be ruled out.
Environmentally unfriendly
Way off target - Doubling nuclear power would reduce greenhouse gas emissions by at most eight per cent.
Not emission free - Mining and transporting uranium, building nuclear plants and storage of nuclear waste all produce carbon dioxide emissions.
Only electricity - It will not replace petrol and diesel - currently responsible for around 22 per cent of UK carbon emissions.
Security threat
Weapons - Uranium enrichment plants can be misused to make nuclear weapons.
Vulnerable - No nuclear reactor could withstand a direct hit from a jumbo jet.
Nowhere to hide - A successful attack could have an impact 40 times worse than the explosion at Chernobyl.
Real alternatives
No need for nuclear - The UK's vast renewable resources combined with simple energy-saving tactics provide a safer, cleaner and more sensible solution.
Secure supply - Renewable sources could generate more than half our current electricity needs by 2025.
Quick technology - All the major renewable technologies can be implemented within three years. We'd be waiting at least ten for nuclear.
Bright idea - A programme to phase out inefficient light bulbs could save a whole reactor's worth of electricity by 2020.
Forward thinking - We could save fifteen reactor's worth by investing in the potential of using waste heat to generate electricity.
