P-ISM is a “Pen-style Personal Networking Gadget Package”. This technology is a technology of five gadget package which has five functions: 1. Pen-style cellular phone provide handwriting data input function. 2. Virtual Keyboard.
3. Compact size Projector.
4. Camera Scanner.
5. Personal ID key with cashless pass function.
These five gadgets communicate with each other by the use of short-range wireless technology. This technology uses the cellular phone function to set up a connection with the internet . Bluetooth is extensively used because this technology permits to transmit data(like songs, files, photos, phone numbers etc.) or construct connections without wires. This is very effective because we can able to connect at anywhere and at anytime 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 Bluetooth.
The LED Projector takes the place of monitor 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 gives more clarity and good picture.
Virtual Laser Keyboard (VLK)is a new gadget for PC users which replaces the hardware—keyboard. It through laser beam onto the desk or onto the flat surface where you can find the full-size perfectly operating QWERTY arrangement keyboard which connects to the PC as well as to other handheld devices(PDA’s , tablet PC’s etc.).
Its working is like the...
