Patent number: 11972272Abstract: An application server provides an application to client devices. Users of the client devices interact with the application to perform a business process. Data regarding user interactions with the application is transmitted from the client devices to the application server. Based on an analysis of the received data, a bot generation server generates a bot to automate a process step. The bot generation server provides a heatmap user interface (UI) that provides information regarding the process steps. Using the heatmap UI, the administrator selects a process step for automation. In response to the selection, the hot generation server identifies, based on the observed behavior, relationships between input fields, typical values for input fields, typical order of data entry into input fields, or any suitable combination thereof. Based on the identified patterns, the hot generation server generates a bot to automate some or all of the process step.Type: GrantFiled: March 9, 2021Date of Patent: April 30, 2024Assignee: SAP SEInventors: Gregor Berg, Andre Niklas Wenz, Bernhard Hoeppner, Thomas Bodner, Olga Cherepanova, Lasse Steffen, Jan Siebert, David Hennemann, Pascal Schulze, Konstantin Dobler, Kris-Fillip Kahl, Paul Udo Beneke, Philipp Bernhard Hoberg

Patent number: 11242787Abstract: Selective catalytic reduction systems are known and are generally included in exhaust systems of diesel engines in order to treat the exhaust gases of such engines. Such systems involve the introduction of diesel exhaust fluid (DEF) into exhaust gas flowing in an exhaust passage of an engine. When dosing DEF onto a hydrolysis catalyst in a SCR system, the DEF will under certain conditions cool the hydrolysis catalyst sufficiently to either slow down or effectively prevent ammonia release, which creates a lag or delay in the function of the hydrolysis catalyst. This limits the amount of control which can be exerted over ammonia storage in the SCR catalyst, and NOx conversion. In a first step, a set of measurement data is received from one or more sensors provided in the system.Type: GrantFiled: December 11, 2017Date of Patent: February 8, 2022Assignee: Perkins Engines Company LimitedInventors: Leo Shead, Alexis Eden, Ronald Silver, Thomas Steffen

Publication number: 20150012002Abstract: The device for injecting a high viscosity material into a cannula includes a body having a material-moving member disposed therewithin which separates the body into a first cavity adapted to receive an incompressible fluid and a second cavity adapted to receive a high viscosity material. A pressure applicator, including a housing having incompressible fluid, is remote from but connected to the body by an extension line providing fluid flow between a fluid outlet of the pressure applicator and the first cavity. First and second check valves within the housing control the flow through the housing. The power piston generates negative pressure within the housing to draw the incompressible fluid in when the piston is extended, and generates positive pressure within the housing, forcing the incompressible fluid out through the second check valve and the fluid outlet and into the first cavity of the non-compliant body, when the piston is depressed.Type: ApplicationFiled: September 22, 2014Publication date: January 8, 2015Inventors: Thomas Steffen, Demetrios Giannitsios, Lorne Beckman
