A novel sustainable source was developed for an existing Italian lighthouse, exploiting the light emitting diode (LED) technology and the norms evolution. The research work started with the optical design of the device, while this work concerns the realization, installation, and test of the new LED lamp. The lamp recombines multiple separated LEDs, realizing a quasipunctual localized source. Af...

Gating The breathing cycle was divided into eight parts by using a respiratory signal. This signal was acquired by laying a belt around the patient's waist with a black disc containing a white spot in the center. The position of this spot was tracked with the help of a video camera. A light emitting diode (LED) was used for synchronizing the respiratory signal with the listmode PET data. The PE...

This paper reviews the key market and technology drivers associated with the emerging application of light emitting diode (LED) technology in the lighting of buildings. The primary focus of this paper is to present and discuss the evolving marketplace, the technology, and how current market and regulatory pressures will form the key drivers for nearand long-term market penetration for emerging ...

This paper presents results from an electronic interface that significantly improves the stability, power output, and spectral flexibility of light emitting diode (LED)-based systems used to excite fluorescence or other forms of luminescence. LEDs are an attractive alternative to conventional white-light sources used in fluorescence analysis because of reduced power of operation, enhanced modul...

This paper describes a new ranging technique using optical signals. The proposed technique is called LT-PAM (Long-Term Phase Accordance Method), and it has been extended from our own ranging technique called Phase Accordance Method (PAM). LT-PAM transmits multiple sync patterns composed of two sinusoidal waves with different frequencies. Unlike chirp modulation techniques, LTPAM transmits the t...
