Publication number: 20190128348Abstract: A brake disc for arrangement in a vehicle to rotate around a rotational axis includes first and second annular braking surfaces extending radially between an inner braking surface radius and an outer braking surface radius. Each of the first and second braking surfaces has an annular proximal portion, an annular distal portion, and an annular central portion. At least one of the first and second braking surfaces is structured to protrude from a base plane perpendicular to the rotational axis to exhibit a surface profile cross-section with a plane including the rotational axis. A protrusion distance from the base plane to the surface profile cross-section as a function of radial distance from the rotational axis exhibits a minimum protrusion distance at a minimum protrusion radial position in the central portion, and the protrusion distance increases with increasing radial distance from the minimum protrusion radial position everywhere in the central portion.Type: ApplicationFiled: April 18, 2017Publication date: May 2, 2019Applicant: VOLVO TRUCK CORPORATIONInventors: Staffan JOHANSSON, Tobias ANDERSSON

Publication number: 20100274574Abstract: The present invention relates to a computerized healthcare management method for a patient. The method uses an interactive conversation tool which strengthens and structures prevention consultations regarding lifestyle changes. The patient is involved actively in the conversations and an overview of the measures/actions to be taken is established. According to the invention, a special navigation compass is provided with a view to creating the best possible overview, said navigation compass dividing and structuring the action plan, while at the same time compass changes in the form of resources and gains can be monitored and followed by the patient. By this, a method is achieved, which discloses the results to the patient to a higher extent than previously and thus creates a better structure and overview than before by means of simple data structures and simple data processing.Type: ApplicationFiled: April 23, 2009Publication date: October 28, 2010Inventors: Tobias Andersson, Lasse Strand Holm, Annette Andersson, Christa Lykke
