Patent number: 11646977Abstract: The avionic system of an aircraft includes a set of avionic computers and a switch associated with each avionic computer. For each avionic computer of the set of avionic computers, the avionic system includes a communication link between the switch associated with this avionic computer and each of the switches associated with the other avionic computers. Each switch is configured such that it routes the data frames received on its input ports to its output ports in a manner predefined only on the basis of the input ports on which these data frames are received. The various switches are configured such that, when an avionic computer sends a data frame, this data frame is transmitted to all of the other avionic computers.Type: GrantFiled: November 12, 2020Date of Patent: May 9, 2023Assignee: AIRBUS OPERATIONS SASInventors: Dominique Portes, Sylvain Sauvant, Gilles Lartigue, Bertrand Deshayes, Sébastien Lefebvre

Publication number: 20160206972Abstract: A chromatography column design and a packing device, as well as a method for obtaining a column with a very compact and uniform bed are provided. The bed remains compact and uniform during operation of the column and during sanitization, storage and transportation of the column. The amount of hardware, particularly the hardware parts in contact with product, is minimized, especially with the implementation of an internal liner. With this internal liner, the packed bed can be separated from the column in intact form, or even prepared separately from, and outside of, the column.Type: ApplicationFiled: March 11, 2016Publication date: July 21, 2016Applicant: Bio-Rad Laboratories, Inc.Inventors: Sébastien Lefebvre, Lilian Portier, Maurice Agée

Patent number: 8741135Abstract: A preparative chromatography column is equipped with one or more valves that can each be used to both inject a column packing into the column or withdraw used packing from the column, in addition to cleaning the supply and discharge lines associated with the valve itself, all by moving a movable plug within the valve body and all without protruding into the column interior. Each valve is mounted on the lateral wall of the column just above the filter plate at the column floor, and the plug is movable between a closed position in which the end surface of the plug is flush with the inner wall of the column and an open position in which the plug is recessed within the bore. Each valve has two additional ports in its valve body, positioned such that when the plug is closed, both ports are open to the valve bore, and when the plug is open, at least one of the ports is open to the bore. The position of the plug within the valve bore determines the valve function.Type: GrantFiled: April 6, 2010Date of Patent: June 3, 2014Assignee: Bio-Rad Laboratories, Inc.Inventors: Maurice Agee, Sebastien Lefebvre, Sebastien Magnaud, Philippe Vernot

Patent number: 8562826Abstract: The plunger used as the upper enclosure in a preparative chromatography column is suspended by one or more rods that are supported by a frame through coupling connections on the frame that can fix the position of the rod(s) relative to the frame, while the position of the rod(s) is controlled by a motorized drive system that is suspended above the column. The drive system is mounted either to the column lid or to a functional plate positioned a short distance above the column lid. These constructions allow the plunger to be raised and lowered so that the column and its parts can be exchanged, all without the need for a hoist or crane.Type: GrantFiled: February 11, 2010Date of Patent: October 22, 2013Assignee: Bio-Rad Laboratories, Inc.Inventors: Daniel M.

Publication number: 20090134441Abstract: A non-volatile memory element includes a transistor for selecting the element and a capacitor for recording a binary value by electrical breakdown of an insulating layer of the capacitor. A structure of the memory element is modified in order to allow a higher degree of integration of the element within an electronic circuit of the MOS type. In addition, the memory element is made more robust with respect to a high electrical voltage (VDD) used for recording the binary value. The transistor includes a drain in the substrate with electric field drift in a longitudinal direction extending towards the capacitor. The electric field drift region for the drain includes a first extension underneath the gate of the transistor opposite the source and a second extension underneath the insulating layer of the capacitor. Doping of the substrate for the electric field drift region is limited to a region substantially corresponding to a distance between the gate and an electrode of the capacitor.Type: ApplicationFiled: February 4, 2009Publication date: May 28, 2009Applicants: STMicroelectronics S.A., STMicroelectronics (Crolles 2) SASInventors: Philippe Candellier, Thierry Devoivre, Emmanuel Josse, Sebastien Lefebvre
