Patent number: 11855799Abstract: In embodiments of an autonomous vehicle platform and safety architecture, safety managers of a safety-critical system monitor outputs of linked components of the safety-critical system. The linked components comprise at least three components, each of which is configured to produce output indicative of a same event independent from the other linked components by using different input information than the other linked components. The safety managers also compare the outputs of the linked components to determine whether each output indicates the occurrence of a same event. When the output of one linked component does not indicate the occurrence of an event that is indicated by the outputs of the other linked components, the safety managers identify the one linked component as having failed. Based on this, the outputs of the other linked components are used to carry out operations of the safety-critical system without using the output of the failed component.Type: GrantFiled: July 15, 2019Date of Patent: December 26, 2023Assignee: VAY TECHNOLOGY GMBHInventors: Joshua John Hartung, Peter Brink, Jonathan Lamb, David Paul Miller

Patent number: 7897079Abstract: A method of producing a paperless gypsum/fiber board from a mixture including reinforcing material particles, calcined gypsum and water. A headbox feeds the mixture into a panel forming area (forming pond) over the upper surface of a continuous forming fabric to form a panel mat. Also, a reinforcing mesh is fed over a transverse member, located over a portion of the forming fabric, and into the forming pond to embed the mesh in the mixture. At least a portion of a downstream end of the transverse member is under a downstream portion of the headbox or downstream of the headbox. Then the panel mat is pressed, the calcined gypsum of the pressed panel mat is rehydrated, and the resulting board is dried.Type: GrantFiled: September 21, 2006Date of Patent: March 1, 2011Assignee: United States Gypsum CompanyInventor: David Paul Miller
