Patent number: 9052560Abstract: A nanoprojector panel formed of an array of cells, each cell including a liquid crystal layer between upper and lower transparent electrodes, a MOS control transistor being arranged above the upper electrode, each transistor being covered with at least three metallization levels. The transistor of each cell extends in a corner of the cell so that the transistors of an assembly of four adjacent cells are arranged in a central region of the assembly. The upper metallization level extends above the transistors of each the assembly of four adjacent cells. The panel includes, for each assembly of four adjacent cells, a first conductive ring surrounding the transistors, the first ring extending from the lower metallization level to the upper electrode of each cell, with an interposed insulating material.Type: GrantFiled: June 18, 2013Date of Patent: June 9, 2015Assignees: STMicroelectronics SA, Commisariat A L'Energie Atomique et aux Energies AlternativesInventors: Michel Marty, Flavien Hirigoyen, Josep Segura Puchades, Hélène Wehbe-Alause, Umberto Rossini

Patent number: 6546801Abstract: A mechanical structure (100) comprises a moving mass (3) suspended by beams (4, 5, 6, 7) from a fixed frame (2). The structure (100) comprises elongation means (23-26) mechanically connected to each of the beams (4, 5, 6, 7). The elongation means is designed such that the stiffness of the beams (4, 5, 6, 7) varies only little during movement of the moving mass. The structure is characterized in that the response of an elongation means is asymmetric when acting in tension and in compression. The structure is thus made insensitive to accelerations along a direction parallel to the suspension direction.Type: GrantFiled: April 23, 2001Date of Patent: April 15, 2003Assignees: Commissariat a l'Energie Atomique, Thomson CSFInventors: Elisabeth Orsier, Bernard Diem, Hélène Wehbe-Alause, Olivier Lefort

Patent number: 6520015Abstract: Diapason type gyrometers using a micro-mechanical structure of vibrating beams. The gyrometer includes a micro-machined sensitive element with at least two symmetrically positioned excitation beams on each side of and parallel to a sensitive Oy axis of the gyrometer. The two beams are connected at their ends through at least one transverse element fixed in its central part to the sensitive Oy axis, to a frame through an elastic torsion return element acting in opposition to the rotation of the transverse element about the Oy axis. The elastic return elements are sized such that the variation of their resonant natural frequency in torsion with temperature is similar to the variation of the resonant natural frequency in bending of the beams with temperature. Such a device may find particular application in the measurement of the angular velocity of a mobile.Type: GrantFiled: May 24, 2001Date of Patent: February 18, 2003Assignee: Thales Avionics S.A.Inventors: Hélène Wehbe Alause, Fabien Formosa
