20080309501 | Electronic System for Defence Against Fires in Forest Areas and More Generally for Monitoring the Territory - The invention refers to an electronic system for defence against fires in forest areas and more generally for monitoring the territory. The system comprises a network of alarm stations (SA) distributed over the territory being controlled, where each alarm station (SA) is enclosed in an air-scaled mechanically-sealed protective casing and comprises at least one sensor (S | 12-18-2008 |
20100134194 | SURFACE ACOUSTIC WAVE DRIVING CIRCUIT AND OSCILLATOR THEREFOR - A driving circuit of a surface wave resonator (X | 06-03-2010 |
20130063316 | COMPACTED PATCH ANTENNA - A compacted patch antenna is described, particularly for installation in a vehicle, comprising an electrically supplied strip radiating element and a ground plane. The strip radiating element is connected to the ground plane at a first end by means of a metal link and at a second end, opposite to the first end, by means of a variable capacitor. The compacted patch antenna comprises a printed circuit, the bottom surface of which is integral with the ground plane, a dielectric material layer arranged between the strip radiating element and the printed circuit; the strip radiating element is substantially parallel to the ground mass. The dielectric material layer has a relative dielectric constant ranging between 3 to 6 with a loss factor ranging between 0.03 to 0.1. | 03-14-2013 |
20140065995 | RECEIVER OF RADIO FREQUENCY SIGNALS - There is described a receiver of at least one radiofrequency modulated signal deriving from an antenna external to the receiver; the receiver comprises a first stage for the low noise amplification of the radiofrequency modulated signal and a demodulation stage of the above-mentioned signal. The receiver comprises a SAW filter adapted to act as a pass band filter about a predetermined frequency for the signal deriving from the first stage, a logarithmic amplifier adapted to amplify the signal deriving from the SAW filter, a peak detector of the output signal of the logarithmic amplifier, means adapted to control the gain of the first stage for the amplification of the radiofrequency modulated signal as a function of the output signal (Vopeak) of the peak detector. | 03-06-2014 |

20090004426 | Suppression of Oxygen Precipitation in Heavily Doped Single Crystal Silicon Substrates - This invention generally relates to a process for suppressing oxygen precipitation in epitaxial silicon wafers having a heavily doped silicon substrate and a lightly N-doped silicon epitaxial layer by dissolving existing oxygen clusters and precipitates within the substrate. Furthermore, the formation of oxygen precipitates is prevented upon subsequent oxygen precipitation heat treatment. | 01-01-2009 |
20090004458 | Diffusion Control in Heavily Doped Substrates - This invention generally relates to a process for suppressing silicon self-interstitial diffusion near the substrate/epitaxial layer interface of an epitaxial silicon wafer having a heavily doped silicon substrate and a lightly doped silicon epitaxial layer. Interstitial diffusion into the epitaxial layer is suppressed by a silicon self-interstitial sink layer comprising dislocation loops. | 01-01-2009 |
