Abstract: A non-transitory computer-readable storage medium, a system and method for automatically updating a multi-hierarchal representation of the system when building and tracking an automation engineering environment, wherein navigation schemes that automatically search for and connect to engineering objects based on predefined relations in multi-dimensional hierarchies are defined within an engineering object of the automation project in order to react to changes within a multi-disciplinary automation project, where the engineering object also includes an intelligent extraction port that automatically extracts predefined property data from a source engineering object when the source engineering object is connected to the engineering object.

Abstract: A handheld pressing device for connecting two work pieces, in particular a pipe and a press fitting by means of a pressing process, has a pressing tool with multiple pressing jaws. The pressing tool is connected to a converter driven by an electric motor. The electric motor and the converter are partly surrounded by a housing. The pressing device has at least one data detecting element, at least one data detecting element being a camera. Furthermore, the camera is used as a data detecting element for documenting pressing processes in a method.

Abstract: In the case of a method for automatically controlling an electrohydraulic pressing tool, in particular for producing pipe connections, to actuate the pressing tool a hydraulic piston is moved, in that fluid is pumped into a hydraulic cylinder by a hydraulic pump driven by an electric motor. When a limiting pressure in the hydraulic cylinder is reached, a pressure relief valve opens, and so the hydraulic fluid can flow into a reservoir. With the aid of a control device, a current drop at the motor is detected when the valve opens. The electric motor is switched off when the current falls by a predetermined value (?I) and/or decreases over a predetermined time period (?t) after reaching a limiting current.

Abstract: A manual press device for connecting two work pieces by means of embossing, comprising a press tool, a converting device, and an electric motor. The electric motor is designed as a brushless electric motor, and preferably connected directly to a hydraulic pump without interconnecting a transmission.

Abstract: A system, method, and computer program for preserving design intent of a Non-Uniform Rational B-spline (NURBS) surface without representation of a parent surface, comprising representing an output surface having control points that is independent from a refinement of the surface; interpolating a base surface from the output surface; calculating a delta vector that is a difference between the output surface and the base surface; and transforming the delta vector based upon a local coordinate system of a normal vector and a tangent plane of the base surface and appropriate means and computer-readable instructions.
