Publication number: 20230343217Abstract: A method of calculating a collision point between an ego vehicle and a target vehicle and to emergency-brake-assist deceleration using the calculation. The calculation defines areas of collision risk of the ego vehicle, determines movement of the ego and target vehicle, calculates times-to-collision for first and second ego-vehicle intersecting points and a target-vehicle intersecting point to an intersection point. A risk collision point condition establishes that the collision point is inside an ego vehicle area if the first time-to-collision for the first ego-vehicle intersecting point reaching the intersection point is less than a third time-to-collision for the target-intersection point reaching the intersection point, and the second time-to-collision for the second ego-vehicle intersecting point reaching the intersection point is greater than the third time-to-collision for the target intersection point reaching the intersection point.Type: ApplicationFiled: April 21, 2023Publication date: October 26, 2023Applicant: Continental Autonomous Mobility Germany GmbHInventors: Mihai Marius Ciuca, Paul Cristian Bucataru, Matthias Lorenzen, Andreas Kramer

Patent number: 11680132Abstract: A curing agent for epoxy resins has N-benzylethane-1,2-diamine and N,N?-dibenzylethane-1,2-diamine in a weight ratio in the range from 65/35 to 95/5. The curing agent is easy to prepare, thins epoxy resins particularly well, and enables low-emission epoxy resin products that have good workability and a long pot-life, cure reliably and surprisingly fast and can be walked on after a short time, in particular even in cold conditions. Coatings of particularly high mechanical grade, with a high surface quality and a minimal tendency to yellowing, can thus be produced. Epoxy resins of this type are particularly suitable for coating floors.Type: GrantFiled: October 1, 2019Date of Patent: June 20, 2023Assignee: SIKA TECHNOLOGY AGInventors: Edis Kasemi, Andreas Kramer, Ursula Stadelmann, Urs Burckhardt
