Publication number: 20130063316Abstract: 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.Type: ApplicationFiled: May 20, 2011Publication date: March 14, 2013Inventors: Guido Moiraghi, Luca Moiraghi, Paolo Moiraghi

Publication number: 20110250739Abstract: 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.Type: ApplicationFiled: June 21, 2011Publication date: October 13, 2011Applicant: MEMC ELECTRONIC MATERIALS, INC.Inventors: Robert J. Falster, Vladimir V. Voronkov, Luca Moiraghi, DongMyun Lee, Chanrae Cho, Marco Ravani

Publication number: 20080309501Abstract: 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 (S1-S3), a microcontroller (MC), a transceiver (RTX) at low power radiofrequency fitted with antenna (A) and a battery (B) for the electric powering of said sensor (S1-S3), said microcontroller (MC) and said transceiver (RTX). The alarm station network (SA) is in wireless communication with at least one intermediate detection unit (CIR) in turn in communication with at least one central control station (SC) controlled by bodies authorised to control and defend the territory.Type: ApplicationFiled: July 29, 2005Publication date: December 18, 2008Inventors: Alberto Redaelli, Guido Moiraghi, Tania Pozzi, Luca Moiraghi

Patent number: 6878302Abstract: The method comprises the steps of mounting a first wafer (13) on the mounting member (12) and securing the mounting member to the hub (16) by drawing a vacuum at a first vacuum pressure through the hub; rotating the hub about the hub axis (AH), rotating a polishing pad (34) mounted on the turntable (30) about the turntable axis (at), and bringing a surface of the wafer (13) and the polishing pad into contact with each other. The wafer (16) is demounted, and the shape of the polished wafer is determined. A second vacuum pressure is selected using the information obtained. A successive wafer is polished according to the same method as the first wafer except that the second vacuum pressure is substituted for the first vacuum pressure. The second vacuum pressure is sufficient to deform the mounting member (12) thereby deform the wafer to improve the flatness and parallelism of the surfaces of the successive wafer.Type: GrantFiled: March 30, 2000Date of Patent: April 12, 2005Assignee: MEMC Electronic Materials, SpAInventors: Paride Corbellini, Giovanni Negri, Ezio Bovio, Luca Moiraghi
