In this paper we introduce a simple, computationally inxepentsive, adaptive recursive structure for enhancing bandpass signals highly corrupted by broad-band noise. This adaptive algorithm, enhancing input signals, enables us to estimate the center frequency and the bandwidth of the input signal. In addition, an important feature of the proposed structure is that the conventional bias existing ...

This paper describes the development of a multi-user interactive display in the coffee corner that makes the office workers aware of events happening within the company aiming to stimulate social interaction. New input devices, iCandies (fake candies integrated with RFID tags) are used as multi-user input devices for explicit interactions with the display. The interactive display and iCandies h...
