Imagine a scenario where the memory stored in your digital camera or personal digital assistant is partially based one of the most flexible materials made by man: plastic.
Scientists at HP Labs and Princeton University are excited a new memory technology that could store more data and cost less than traditional silicon-based chips for mobile devices such as handheld computers, ell phones and MP3 players. A conducting plastic has been used to create a new memory technology with the potential to store a megabit of data in a illimetre-square device – 10 times denser than current magnetic memories.
The device should also be cheap and fast, but cannot be rewritten, so would only be suitable for permanent storage. The device sandwiches a blob of a conducting polymer called PEDOT (POLYETHYLENE DIOXYTHIOPENE) and a silicon diode between two perpendicular wires. Substantial research effort as focused on polymer-based transistors, which could form cheap, flexible circuits, but polymer-based memory has received relatively little attention.
The beauty of the device is that it combines the best of silicon technology – diodes – with the capability to form a fuse, which does not exist in silicon,” says Vladimir Bulovic, who works on organic lectronics at the Massachusetts Institute of Technology. However, turning the polymer INTO an insulator involves a permanent chemical change, meaning the memory can only be written o once. Its creators say this makes it ideal for archiving images and

Imagine watching a football match on a TV that not only shows the players in three dimensions but also lets you experience the smells of the stadium and maybe even pat a goalscorer on the back.
Japan plans to make this futuristic television a commercial reality by 2020 as part of a broad national project that will bring together researchers from the government, technology companies and academia. The targeted “virtual reality” television would allow people to view high-definition images in 3D from any angle, in addition to being able to touch and smell the objects being projected upwards from a screen to the floor.
Can you imagine hovering over your TV to watch Japan versus Brazil in the finals of the World Cup as if you are really there?” asked Yoshiaki Takeuchi, development at Japan’s Ministry of Internal Affairs and ommunications. While companies, universities and research institutes around the world have made some progress on reproducing 3D images suitable for TV, developing the technologies to create the sensations of touch and smell could prove the most challenging, Takeuchi said in an interview with Reuters.
Researchers are looking into ultrasound, electric stimulation and wind pressure as potential technologies for touch. Such a TV would have a wide range of potential uses. It could be used in home-shopping programs, allowing viewers to “feel” a andbag before placing their order, or in the medical industry, enabling doctors to view or even perform simulated surgery on 3D images of omeone’s heart. The future TV is part of a larger national project under which Japan aims to promote “universal communication,” a concept whereby information is shared smoothly and intelligently regardless of location or language.
Takeuchi said an open forum covering a broad range of technologies related to universal communication, such as language translation and advanced Web search techniques, could be established by the end of this ear. Researchers from several top firms including Matsushita Electric Industrial Co. Ltd. and Sony Corp. are members of a report on the project last month. The ministry plans to request a budget of more than 1 billion yen to help fund the project in the next fiscal year starting in April 2006.
Internet technologies, through intranet and extranet applications, have proven themselves to be efficient and effective in streamlining existing processes from supply chain management to manufacturing logistics, from marketing to customer asset management, nd by creating new value chains and businesses. Nevertheless, these changes and benefits signal only an evolutionary shift in the way we do business. The Internet-enabled conomy resembles the conventional physical market in many aspects. Some of the new technologies and applications may even be unnecessary. American consumers, for xample, regard smart cards as a redundant payment mechanism when checks, credit cards and ATM cards do an adequate job for current needs. What is the use of smart ards? Do we really need them? Will they ever take off?
Today, the SIM card’s basic functionality in wireless communications is subscriber authentication and roaming. Although such features may be achieved via a centralized intelligent network (IN) solution or a smarter handset, there are several key benefits that ould not be realized without the use of a SIM card, which is external to a mobile handset. These benefits—enhanced security, improved logistics, and new marketing pportunities—are key factors for effectively differentiating wireless service offerings. This tutorial assumes a basic knowledge of the wireless communications industry and ill discuss the security benefits, logistical issues, marketing opportunities, and customer benefits associated with smart cards.
The smart card is one of the latest additions to the world of information technology (IT). he size of a credit card, it has an embedded silicon chip that enables it to store data and communicate via a reader with a workstation or network. The chip also contains advanced security features that protect the card’s data. Smart cards come in two varieties: microprocessor and memory. Memory cards simply tore data and can be viewed as small floppy disks with optional security. Memory cards depend on the security of a card reader for their processing. A microprocessor card can dd, delete, and manipulate information in its memory on the card. It is like a miniature computer with an input and output port, operating system, and hard disk with built-in ecurity features.

Controll Electrical Home Appliances with your TV Remore.
Just about every piece of domestic hi-fi or video unit comes with a remote control handset these days. Infrared (IR) remote controls are everywhere. Just about every piece of electronic equipment you can think of has one – TVs, VCRs, DVDs, hi-fi systems. Even the lastest cameras have them!
Why are they so popular? The answer is simple convenience. You can change TV channels without leaving your chair. Or adjust the volume on your stereo system. Or, in the case of cameras, be in the photo your self without having to find someone else to take it. Life became so comfortable by such a infrared remote controlled devices.
Now think, it would be so nice if we have remote controller for our whole home, means that can control our all the home appliances, just like – freeze, fan, light, etc…
Prior to DTMF, phone systems used a system known as pulse (Dial Pulse or DP in the USA) or loop disconnect (LD) signalling to dial numbers, which works by rapidly disconnecting and connecting the calling party’s phone line, like flicking a light switch on and off. The repeated connection and disconnection, as the dial spins, sounds like a series of clicks. The exchange equipment counts those clicks or dial pulses to determine the called number. LD range was restricted by telegraphic distortion and other technical problems, and placing calls over longer distances required either operator assistance
(operators used an earlier kind of multi-frequency dial) or the provision of subscriber trunk dialling equipment.
DTMF was developed at Bell Labs in order to allow dialing signals to dial long-distance numbers, potentially over nonwire links such as microwave radio relay links or atellites. For a few non crossbar offices, encoder/decoders were added that would convert the older pulse signals into DTMF tones and play them down the line to the emote end office. At the remote site another encoder/decoder could decode the tones and perform pulse dialing, for example for Strowger switches. It was as if you were onnected directly to that end office, yet the signaling would work over any sort of link. This idea of using the existing network for signaling as well as the message is nown as n-band signaling.
It was clear even in the late 1950s when DTMF was being developed that the future of switching lay in electronic switches, as opposed to the electromechanical crossbar systems then in use. Either switching system could use either dial system, but DTMF promised shorter holding times, which was more important in the larger and more complex registers used in crossbar systems. In this case pulse dialing made no sense at any point in the circuit, and plans were made to roll DTMF out to end users as soon as possible. Tests of the system occurred in the early 1960s, where DTMF became known as Touch Tone. Though Touch Tone phones were already in use in a few places, they were vigorously promoted at the 1964 New York World’s Fair.
