Publication number: 20190171337Abstract: A method of displaying data for the management of the flight of an aircraft includes the steps consisting in receiving the selection of an object on a display screen present in the cockpit of the aircraft; determining one or more flight commands associated with the selected object; selecting at least one flight command from among the one or more determined flight commands; generating a display panel comprising a plurality of display tiles, one of the tiles displaying data associated with the selected object and another tile displaying the flight command selected. Developments describe the updating of the panel as a function of a revision of the flight plan, the displaying of attributes of a flight command, conditional display modifications, modalities of unfurling or of folding of the display tiles, the taking into account of the visual density of display, the use of display rules, in particular as a function of flight context.Type: ApplicationFiled: April 14, 2017Publication date: June 6, 2019Inventors: Jean-Cédric PERRIN, Fany BARAILLER, Yannick LE ROUX, Patrick CAZAUX

Patent number: 9057223Abstract: A technique facilitates drilling of wellbores or other types of bore holes in a variety of applications. A steerable system or other well tool is designed with a plurality of actuators which are positioned to provide controlled steering during a drilling operation. Each actuator includes at least one loose element or ball slidably mounted in a corresponding sleeve. Pressurized fluid is used to provide controlled movement of the elements along the corresponding sleeves of the actuators. The controlled movement of the elements assists in the provision of steering or other control over the well tool during the drilling operation.Type: GrantFiled: June 21, 2012Date of Patent: June 16, 2015Assignee: Schlumberger Technology CorporationInventors: Cedric Perrin, Geoffrey C.
