This paper describes the design and development of a novel digital notice board which allows non experienced users to easily interact with digital information. In particular, the system allows the user to receive and handle media elements (pictures, text messages, videos). Instead of employing the file system to interact with information, the user interface promotes a kind of interaction which ...

Whatever appliances we are dealing with, in our daily life, we want to control them without physically moving to the control unit. As we see in our schools and colleges, we are using ma...

Optimal Antenna Positioning for Wireless Board-To-Board Communication Using a Butler Matrix Beamforming Network

For wireless board-to-board communication the problem of an optimal positioning of antenna arrays on two boards facing each other is described, where each antenna array uses the same kind of Butler matrix beamforming network. We discuss possible design criteria for the positioning problem. To obtain a position with both a high response and a low pathloss for as many as possible links we introdu...
