Patent number: 12054242Abstract: The invention relates to a device for braking a wheel, the device comprising: a brake including at least a first actuator and a second actuator arranged to apply a braking torque to the wheel; a control system arranged to control the first and second actuators individually as a function of a required braking value; and at least a first breaking torque sensor arranged to supply the control unit with a first measurement of the braking torque applied to the wheel by the brake. According to the invention, the control system is arranged to interrupt control of the first actuator or control of the second actuator in the event of the braking torque measured by the first sensor exceeding a predetermined braking torque limit.Type: GrantFiled: July 29, 2020Date of Patent: August 6, 2024Assignee: SAFRAN LANDING SYSTEMSInventors: Emmanuel Brun, Vincent Pavoine, David Frank, Jean-Baptiste Lestage

Patent number: 11384899Abstract: A fastening device includes a self-adhesive part having a self-adhesive surface and a connecting surface which is situated on the opposite side from the self-adhesive surface. A flexible strip extends from the connecting surface of the self-adhesive part. The flexible strip is joined to the self-adhesive part by means of a connecting element disposed in a region on the connecting surface. This region faces a central region of the self-adhesive surface. Thus, a traction force exerted on the flexible strip is distributed substantially uniformly over the self-adhesive surface.Type: GrantFiled: August 20, 2018Date of Patent: July 12, 2022Inventor: Emmanuel Brun
