Patent number: 11243526Abstract: A plurality of basic simulations independent of one another are carried out, which determine respective remaining service life predictions for the machine. The remaining service life predictions and characteristic data are fed to a neural network, which outputs weights for the remaining service life predictions. A final prediction is calculated from the remaining service life predictions by weighting the remaining service life predictions relative to one another. A hybrid model is produced, which results from the combination of the basic simulations with the neural network. The remaining service life can be predicted not only for a small number of machines for which a specific simulation model has been manually created. The hybrid model enables condition monitoring for any further types and configurations of machines that merely belong to the same machine class. The basic simulations can therefore also be applied to previously unknown machines.Type: GrantFiled: August 12, 2019Date of Patent: February 8, 2022Assignee: Siemens AktiengesellschaftInventors: Christoph Bergs, Marcel Hildebrandt, Mohamed Khalil, Serghei Mogoreanu, Swathi Shyam Sunder

Patent number: 5056040Abstract: There is disclosed an electric balance with a sensor (2), a digital signal processing unit (4), a digital display (5) and switching means (6) which suppress the leading zeros in the digital display by a control means (7) which activates and deactivates the switching means (6) for suppressing leading zeros as a function of the sign of the result of measuring. In this manner, a change of sign can be signaled more clearly. It is also possible to display more leading zeros as the magnitude of the deviation of the result of measuring from the value zero increases so that the leading zeros appear in several stages, starting from zero up to a set measuring value.Type: GrantFiled: September 27, 1988Date of Patent: October 8, 1991Assignee: Sartorius AGInventors: Franz-Josef Melcher, Christoph Berg, Christian Oldendorf

Patent number: 4890246Abstract: In high-resolution electric balances a certain residual temperature coefficient remains even with a good correction of the temperature-dependent errors of the measured value sensor. The invention therefore is with respect to a balance with a built-in calibrating weight (standard) which responds with a new calibration switching in said calibrating weight if a given temperature changes has been exceeded since the last calibration. To this end, the balance comprises in microprocessor digital signal processing unit a separate memory area in which the output signal representing temperature value of a temperature sensor is stored during the calibrating process and also comprises a comparator which upon instruction compares the instantaneous output signal of the temperature sensor which the value stored in this separate memory area. If this difference exceeds a given amount, a signal element indicative of need to recalibrate using the calibrating weight is actuated.Type: GrantFiled: November 19, 1987Date of Patent: December 26, 1989Assignee: Sartorius GmbHInventors: Christian Oldendorf, Christoph Berg, Franz-Josef Melcher

The signals can be formed by light sources adjacent to the balance scale (1) or in the corners or on the sides of the display field (9).Type: GrantFiled: October 19, 1988Date of Patent: July 18, 1989Assignee: Sartorius GmbHInventors: Christian Oldendorf, Franz-Josef Melcher, Christoph Berg

Patent number: 4656599Abstract: It is necessary, when high requirements are demanded from balances, that the effect of different disturbance variables such as, e.g., temperature and/or moisture on the measuring system be corrected. To this end, temperature and moisture sensors are used from whose output signal correction values are calculated. The invention suggests that a storage area be provided into which the instantaneous measured results of these sensors are stored in succession, where they remain stored for a set time. This data stemming from different times, evaluated with set weighting factors, could then be used to calculate the corrections. This makes it possible to obtain a good correction of changing disturbances even with a different behavior in time of sensors and measuring system.Type: GrantFiled: October 26, 1984Date of Patent: April 7, 1987Assignee: Sartorius GmbHInventors: Erich Knothe, Franz-Josef Melcher, Jurgen Ober, Christoph Berg, Klaus Dardat, Eduard Bierich, Gunther Maaz

Patent number: 4653600Abstract: In a parallel rod guide for electronic balances having a measured value sensor, typically corner load adjustments are made by adjusting the parallelism of the two rods and such adjustments are normally sufficient. However, this can eliminate only linearly load-dependent corner load errors. In order to eliminate corner load errors which are non-linearly dependent on the load, the present invention provides an adjustment assembly which varies the resilience of the fastening points on the system carrier side of at least one rod to horizontal forces. The adjustment assembly may comprise, a screw/nut connection whose position can be varied vertically therewith, varying the effective length of a resilient intermediate part.Type: GrantFiled: February 11, 1986Date of Patent: March 31, 1987Assignee: Sartorius GmbHInventors: Franz-Josef Melcher, Gunther Maaz, Eduard Bierich, Eberhard Stadler, Christoph Berg

Patent number: 4625818Abstract: The invention suggests an intermittent mode of operation to reduce the stray power in the coil in a balance based on the principle of the electromagnetic compensation of force. To this end, switching means (21) are provided which can interrupt the current flow through the coil (11) so that when the current flow is interrupted, the movable parts (2-9) of the balance move against one of the stops (24) or (25). These switching means (21) are controlled by the digital signal processing unit (18). In addition storage means (20) are provided within the framework of the digital signal processing unit which store the last-determined weight value for the duration of the interruption of the current flow through the coil.Type: GrantFiled: March 18, 1985Date of Patent: December 2, 1986Assignee: Sartorius GmbHInventors: Erich Knothe, Franz-Josef Melcher, Christoph Berg
