Abstract: In a method for stabilization of an object using an electronic stabilizer device, which includes an electric gyroscope, a driver device and a counterweight device. The method measures orientation data of the object using the electric gyroscope, analyzes the orientation data of the object to obtain a current obliquity of the object, and generates a first control signal to drive the driver device according to the current obliquity when the current obliquity is equal to a reference angle. The method controls the counterweight device to change a center of gravity of the object through the driver device, and measures an adjusted obliquity of the object using the electric gyroscope. The method generates a second control signal to drive the driver device when the adjusted obliquity changes, and controls the counterweight device to dynamically adjust the center of gravity of the object.

Abstract: In a method and system for operating a machine from the field of automation engineering, operating inputs entered at an operating unit of the machine and an identification code are transmitted via a data network to communication server software running on an external computing device. The communication server software determines MMI (machine-machine-interface) application software associated with the machine and with the operating inputs and transfers the operating inputs to the MMI application software, which in turn determines visualization data on the basis of the operating inputs. The visualization data specify a graphical output image to be represented on a display screen and are transferred to the machine via the communication server software and the data network for display. The performance characteristics of the machine can thereby be enhanced, without increasing demands on the hardware.
