I am now going to tell about P-ISM (“Pen-style Personal Networking Gadget Package”), which is nothing but the new discovery which is under developing stage by NEC Corporation. At the 2003 ITU Telecom World exhibition held in Geneva, the Tokyo-based NEC Corporation displayed a conceptual $30,000 prototype of P-ISM. It is simply a new invention in computer and it is associated with communication field. Surely this will have a great impact on the computer field. In this device you will find Bluetooth as the main interconnecting device between different peripherals. [pic]
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. Introduction:
Communication Technology is rapidly increasing in this modern world. Computer, as everybody knows, is the main communication machine used. Since the time computer has been invented scientists and engineers have been trying making it more and more compact. As a result we have been able to enjoy the numerous functionalities provided by the computers whether it is Home PCs or Laptops. Systems have still been reduced so that they are used in Mobiles I-pods and I-phones have replaced the laptops to an extent. It is in this context that Pen Computers come into spot light. These are computers in the shape of different pens each having a function of its own and when combined together give us the usage of a full-blown computer. It is a computer broken apart into pieces, each the size of a pen. The screen and keyboard are projected onto surfaces.
P-ISM means Pen-style Personal Networking Gadget Package. P-ISM is a gadge package including five functions:
Block diagram of P-ISM:
The functionality of the CPU is done by one of the pen. It is also known as computing engine.
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 (Bluetooth, 802.11B/G, and Cellular) which are made small and kept in a small pen like device.
Connectivity 802.11B/G and Bluetooth:
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...
