5 Pen PC Technology

Computer affects our life in a much bigger way then most of us might have thought. It has become a compulsory requirement in most professions to be able to use computer software. The first computer invented was the ENIAC in 1943 which was the same size of a large room, consuming as much power as several hundred modern PCs. Modern computers which are based on integrated circuits are small enough to fit into mobile devices. One of the most compacted computers out right now are table computers with the most popular being the IPad, but even that is 9.1inch and weighing about 700grams. But imagine having a computer will fit on your pencil case.

P-ISM (“Pen-style Personal Networking Gadget Package”), which is nothing but the new discovery, which is under developing, stage by NEC Corporation. P-ISM is a gadget package including five functions: a pen-style cellular phone with a handwriting data input function, virtual keyboard, a very small projector, camera scanner, and personal ID key with cashless pass function. P-ISMs are connected with one another through short-range wireless technology. The whole set is also connected to the Internet through the cellular phone function. This personal gadget in a minimalist pen style enables the ultimate ubiquitous computing

It seems to many of us these days that the pace of technological change is so great that it outstrips our imaginations — just as soon as we can conceive of the next nifty electronic gadget we'd like to have, we find out that somebody has already built it.

Miniaturized devices such as cameras and telephones are examples of now-common technologies that just a few years ago most of us rarely encountered outside the fictional world of spy thrillers. Miniaturized personal computers are the next logical step, but many readers might be surprised to learn that a plan for PC components housed in devices the size and shape of ballpoint pens (as shown above) was showcased by a major electronics company over two years ago.

ISM

P-ISM is a gadget package including five functions: a pen-style cellular phone with a handwriting data input function, virtual keyboard, a very small projector, camera scanner, and personal ID key with cashless pass function. P-ISMs are connected with one another through short-range wireless technology. The whole set is also connected to the Internet through the cellular phone function. This personal gadget in a minimalistic pen style enables the ultimate ubiquitous computing.

The P-ISM system was based on "low-cost electronic perception technology" produced by the San Jose, California, firm of Canesta, Inc., developers of technologies such as the "virtual keyboard" (although the last two pictures shown above appear to be virtual keyboard products sold by other companies such as VKB rather than components of the P-ISM prototype).

P-ISMs are connected with one another through short-range wireless technology. The whole set is also connected to the Internet through the cellular phone function. They are connected through Tri-wireless modes (Blue tooth, 802.11B/G, and Cellular) which are made small and kept in a small pen like device.

Connectivity 802.11B/G and Blue tooth



In fact, no-one expects much activity on 802.11n installations until the middle of 2008. “Rolling out 802.11n would mean a big upgrade for customers who already have full Wi-Fi coverage, and would be a complex add-on to existing wired networks, for those who haven't. Bluetooth is widely used because we can able to transfer data or make connections without wires. This is very effective because we can able to connect whenever we need without having wires. They are used at the frequency band of 2.4 GHz ISM (although they use different access mechanisms). Blue tooth mechanism is used for exchanging signal status information between two devices. This techniques have been developed that do not require communication between the two devices (such as Blue tooth’s Adaptive Frequency Hopping), the most efficient and comprehensive solution for the most serious problems can be accomplished by silicon vendors. They can implement information exchange capabilities within the designs of the Blue tooth. The circuit diagram for the 802.11B/G is given below. It is nothing but also type of Blue tooth. Using this connectivity we can also connect it with the internet and can access it anywhere in the world.

The role of monitor is taken by LED Projector which projects on the screen. The size of the projector is of A4 size. It has the approximate resolution capacity of 1024 X 768. Thus it is gives more clarity and good picture.

5 Pen PC Technology

Portable

The first and most important advantage of the 5 pen pc are that they are portable. Due to its size they can be carried anywhere . These PC’s are in the shape of pens and that’s why they can be carried in small bags or even in our pockets. A portable computer is a computer that is designed to be moved from one place to another and includes a display and keyboard. They can also be called a 'Portable Workstation' or 'Portable PC'.5Pen PC are the most easily portable pc ever made. Another major merit is that its works on battery and so it can be used whenever we want

The another major important merit of a 5 pen pc is that its has a Wi-Fi technology built in it through which the user can connect to the internet very easily. Wifi, is a mechanism that allows electronic devices to exchange data wirelessly over a computer network. A device enabled with Wi-Fi, such as a personal computer, video game console, smart phone, tablet, or digital audio player, can connect to a network resource such as the Internet via a wireless network access point. An access point (or hotspot) has a range of about 20 meters (65 ft) indoors and a greater range outdoors. Hotspot coverage can comprise an area as small as a single room with walls that block radio signals or a large area, as much as many square miles, covered by multiple overlapping access points. To connect to a Wi-Fi LAN, a computer has to be equipped with a wireless network interface controller.
