Abstract: Methods and systems are provided for determining over focalization of a pilot of an aircraft. The method includes receiving human parameter data from one or more systems that observe conditions associated with the pilot and receiving controls data that indicates an interaction of the pilot with one or more control systems of the aircraft. The method includes, based on the human parameter data and the controls data, generating at least one alert. The method also includes communicating the at least one alert to the pilot to change a focus of the pilot.

Abstract: A method and a device are provided for detecting lack of reaction of the crew of an aircraft to an alarm related to a path. The method includes monitoring the emitting condition of a plurality of alarms related to dangers in the path of the aircraft and monitoring a reaction of a crew during first and second time intervals determined based on how long the crew should take to response to the initial alarm in the first time interval and an auxiliary alarm in the second time interval. The method also includes implementing automatic avoidance operation for coping with the danger if the crew has not reacted to the alarms by the end of the second time interval.

Abstract: A method for monitoring the flight of an aircraft using two navigation screens respectively dedicated to a pilot and to a copilot of the aircraft is provided. The method includes displaying on the screens, depending on the choice of the pilot and the copilot, at least information relating to the following of terrain by the aircraft or information relating to meteorological conditions that the aircraft encounters during the flight, triggering at least one warning representative of hazardous meteorological conditions detected by the meteorological radar and liable to be encountered by the aircraft while the navigation screens of the pilot and copilot simultaneously are displaying the terrain-following information, wherein the at least one warning is triggered when the information relating to the hazardous meteorological conditions is located in a predetermined volume relative to the aircraft, and displaying the warning on at least one of the navigation screens.

Abstract: A method and a device for detecting lack of reaction of the crew of an aircraft to an alarm related to a path. The device (1) comprises means (6, 8) for automatically emitting at least one auxiliary alert signal for signalling an alarm related to a path of the aircraft, in case the crew does not react to this alarm.

Abstract: A method for monitoring the flight of an aircraft consisting in triggering a warning representative of hazardous meteorological conditions liable to face the aircraft while the navigation screen is displaying the terrain-following information.

Abstract: Self-compressing screws, especially self-threading screws, include a screw shaft having an axis of revolution, the screw shaft being provided with two threads that are centered on the axis of revolution, and a first envelope in the form of a rotary hollow cylinder defined by the thread, between the base and the tip of an individual thread section, fitting entirely inside the second envelope in the form of a rotary hollow cylinder defined by the thread, between the base and the tip of an individual thread section. A pitch P11 of the thread is smaller than a pitch P22 of the thread. A method of applying the screw for joining two bone segments is also provided in order to perform an osteosynthsis operation between the two bone segments.

Abstract: This invention pertains to an articulated prothesis for a joint such as for a finger. The prosthesis, capable of joining two bones, basically consists of two stems, each having a bearing component integral with one end which together form a hinged joint pivotable about an axis. A snap-on coupling integral with a hinge pin component is provided on each side of the bearing.

Abstract: A stiffening ply intended for use in an article, particularly a pneumatic tire, is characterized by the fact that the ply is formed at least in part of a fabric having the following properties:(a) the fabric has a three-dimensional body and stiffening threads;(b) substantially all the voids in the fabric are capable of being filled by a material which forms part of the structure of the article;(c) the fabric has two main faces connected by two side faces;(d) the cross section of the fabric has a width which varies from one main face to the other.

Abstract: A reinforcement ply intended for use in a tire is characterized by the fact that the reinforcement ply is formed, at least in part, of a fabric having the following properties: (a) the fabric comprises a three-dimensional body and reinforcement threads arranged in the body and held by the body; and (b) practically all the voids in the fabric are capable of being impregnated with at least one material which forms part of the structure of the tire. The invention also relates to these plies which are impregnated with at least one material which forms part of the structure of the tires. The invention further relates to tires having at least one reinforcement ply, as well as to the methods for obtaining such tires.

Abstract: A roller bearing assembly having an outer case (1) which contains an elastically yieldable sleeve 2 in which is enclosed a thin elastically yieldable ring 3 whose inner surface acts as a raceway for rollers or needles (6) carried by the cage (7). The elastic ring has a plurality of angularly spaced apart regions discontinuities (4a, 4b) defining pre-stressed regions adapted to ensure, by a radial deformation, a localized gripping of the rollers or needles under the action of the sleeve when the roller bearing assembly is mounted on a shaft (8). The outer case (1), the sleeve (2), the roller bearing ring (3) and the cage (7) have an openable structure which permit their spreading being apart to an open for ensuring the mounting of the roller bearing assembly by a lateral engagement of its component parts on the shaft without ends of insertion thereon from either each of the shaft.

Abstract: A method of producing continuous lengths of coilable corrugated wave guide of rectangular cross-section which comprises forming a smooth-wall metal tube wth a uniform wall thickness along the entire length and around the entire periphery, and transversely corrugating the walls of the tube along crest and root lines that form a substantially constant perimeter length around any cross-section of the corrugated tube taken perpendicular to the axis of the tube at any point along the length of the tube. In one embodiment, the corrugations of intersecting walls are offset at their intersection so that the crests of the corrugations of each wall meet the roots of the corrugations of the adjacent wall at each corner, with zigzag crests along the corners providing rigidity.

Abstract: A method and apparatus for producing continuous lengths of coaxial products, such as coaxial cable, having concentric inner and outer conductors or other members, and an intermediate layer of dielectric or insulating material between the inner and outer members. A continuous length of the inner member is continuously advanced while a concentric layer of insulating material is continuously formed on the outer surface of the inner member, with the radial thickness of the insulating layer increasing in the machine direction in a predetermined zone traversed by the continuously advancing inner member. A continuous flat metal strip is continuously advanced alongside the inner member and is formed into an outer member surrounding the inner member, after which the longitudinal edge portions of the rolled strip are joined before the insulating material reaches its maximum radial thickness.
