  • Publication number: 20190376551
    Abstract: A stationary thrust bearing is for a stationary and rotating thrust bearing system designed to withstand an axial load along an axis of a rotation shaft mounted in a guide bearing, in particular of a turbocharger. The stationary thrust bearing includes a flange in which is created a through-opening that allows the rotation shaft to pass through and has, on a face, pads with structured regions. Specifically, at least two sets of the pads, which include a first set of pads with structured regions present in a first ring on the face of the flange, and a second set of pads with structured regions present in a second ring, coaxial with the first ring, on the face of the flange, set back relative to the first set of pads in the longitudinal direction of the axis of the opening.

  • Patent number: 10481787
    Abstract: A touch interface includes a display screen and detects an approach and a position of a user's finger with respect to the screen. The interface displays at least one first graphical element associated with a first touch selection zone and lying in a first region and at least one second graphical element superimposed on a second touch selection zone, and lying in a second region distinct from the first region. The interface estimates a trajectory of a point of the finger and a point of impact of the trajectory on the screen. The interface displaces, when the point of impact is detected in one of the regions, the graphical element of the region and the associated touch selection zone in the direction of the point of impact, and then, when the point of impact exits the region, restore the display of the graphical element to an initial state.

  • Patent number: 10465622
    Abstract: A basic opening (A0) of an EGR control valve (22) is set, based on a current engine operation state. A differential pressure (?P1) across the EGR control valve (22) is calculated, based on an actual exhaust system temperature (T1) sensed by an exhaust temperature sensor (33). A reference differential pressure (?P0) is calculated, which is a differential pressure across the EGR control valve (22) in a steady state corresponding to the current engine operation state. A reference pulsation amplitude (D) is calculated, which is an amplitude of pulsation of the reference differential pressure (?P0). The basic opening (A0) is corrected, based on the differential pressure (?P1), the reference differential pressure (?P0), and the reference pulsation amplitude (D).
