In this work, an illumination interference reduction technique for visible light communications (VLC) is presented. In this kind of systems an optical wireless communication is established using visible light wavelength, therefore optical filtering for interference rejection can not be employed. Instead of the optical filtering a signal processing based(More)

Lomefloxacin (SC 47111, NY-198) is a recently developed difluorinated quinolone that has been reported to be active against a broad range of both gram-positive and gram-negative pathogens in a number of laboratories around the world. Our laboratory tested the in vitro activity of 451 recent bacterial isolates compared to that of cephradine and gentamicin to(More)
Distance estimation plays an important role in location-based services, which has become very popular in recent years. In this paper, a new short range cricket sensor-based approach is proposed for indoor location applications. This solution uses Time Difference of Arrival (TDoA) between an optical and an ultrasound signal which are transmitted(More)
