Journal ArticleDOI
New control strategy in a square-wave inverter for low wattage metal halide lamp supply to avoid acoustic resonances
J. Garcia-Garcia,Jesus Cardesin,Javier Ribas,A.J. Calleja,Emilio López Corominas,Manuel Rico-Secades,J.M. Alonso +6 more
TL;DR: In this paper, a new control strategy for a high frequency (HF) square wave inverter is presented, which keeps lamp power harmonics at low levels, regardless of the lamp equivalent load.
Proceedings ArticleDOI
Comparison Among Power LEDs for Automotive Lighting Applications
TL;DR: A comparison among the most efficient red, amber/yellow and white Power LEDs currently available from the leading manufacturers is proposed, offering a comparison in terms of luminous efficiency in nominal test conditions, thermal resistance between the junction and the slug and also giving a comparison about the performance depending on junction temperature between the two most efficient LEDs for each colour.
Journal ArticleDOI
Chromothripsis Is a Recurrent Genomic Abnormality in High-Risk Myelodysplastic Syndromes
María Abáigar,Cristina Robledo,Rocío Benito,Fernando Ramos,María Díez-Campelo,Lourdes Hermosín,Javier Sánchez-del-Real,J.M. Alonso,Rebeca Cuello,Marta Megido,Juan N. Rodríguez,Guillermo Martín-Núñez,Carlos Aguilar,Manuel Vargas,Ana A. Martín,Juan Luis García,Alexander Kohlmann,M. Consuelo del Cañizo,Jesús M. Hernández-Rivas,Jesús M. Hernández-Rivas +19 more
TL;DR: The presence of chromothripsis involving chromosome 13 was a novel recurrent change in high-risk MDS patients and revealed the presence of cryptic abnormalities in genomic regions where MDS-related genes, such as TET2, DNMT3A, RUNX1 and BCOR, are located.
Journal ArticleDOI
Magnetic dimming of electronic ballasts
TL;DR: In this article, a new control method for electronic ballasts based on magnetic regulators is presented, which allows starting and dimming the lamp at constant frequency by adjusting the inductance of the resonant tank.
Proceedings ArticleDOI
Evaluation of a high efficiency boost stage to supply a permanent LED emergency lighting system
A.J. Calleja,Manuel Rico-Secades,Jesus Cardesin,Javier Ribas,Emilio López Corominas,J.M. Alonso,Jorge Garcia +6 more
TL;DR: In this article, a boost converter to supply a permanent emergency lighting system based on LED was developed to assure a constant current through LEDs for all the battery conditions, and a 30 lumens and 1 hour PELS was built and tested.
