Patent number: 11777967Abstract: A method, an intelligent switch, a device, and a network for recognizing deviations in communication behavior of the network are provided. Characteristics of communication are monitored and evaluated regarding security behavior of the network using a model of a communication behavior of the network. For each communication over a switch of the network, at most three security values are derived from communication metadata of the respective communication using the model of the communication behavior. For each communication, it is checked whether the respective at most three security values meet respective predetermined threshold values. When the respective predetermined threshold values are not met by at least one of the security values, a security warning is generated.Type: GrantFiled: December 3, 2019Date of Patent: October 3, 2023Assignee: Siemens AktiengesellschaftInventors: Jens Makuth, Jürgen Schimmer

Patent number: 9664720Abstract: A device for the contactless determination of an electrical potential of an object, has an electrode and a potential controller which is electrically connected to the electrode. The potential controller changes a reference potential applied to the electrode to a final value in such a way that an electric field between the object and the electrode disappears at the final value if the electrode is located at a distance from the object. The electrical potential is determined from the final value.Type: GrantFiled: April 14, 2011Date of Patent: May 30, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Jens Makuth, Dirk Scheibner, Jürgen Schimmer

Method for contactless determination of electrical potential using oscillating electrode, and device
Patent number: 9121878Abstract: The electrical potential of an object is determined by providing a mechanically oscillating electrode located at a distance from the object and making the electrode mechanically oscillate. A change in a state of electric charge of the electrode over time and amplitudes of at least two frequency components during the change in the state of electric charge over time are determined. Based on the amplitudes, at least one parameter that forms part of the value of a capacitance of an arrangement formed by the electrode and the object is determined, so that the capacitance of the arrangement formed by the electrode and object can be determined based on the parameter. Finally, the electrical potential is determined from the change in the state of electric charge and the capacitance.Type: GrantFiled: April 14, 2011Date of Patent: September 1, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Jens Makuth, Dirk Scheibner, Jürgen Schimmer -

Publication number: 20130043865Abstract: A current measurement is implemented with the aid of magnetoresistive sensors or Hall sensors. The sensors are arranged on one or two printed circuit boards, which provide a passage when coupled to one another, through which passage an electrical line passes. The printed circuit boards can also be fitted retrospectively to electrical lines, with the result that the electrical lines need not be interrupted.Type: ApplicationFiled: August 14, 2012Publication date: February 21, 2013Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Jens MAKUTH, Dirk SCHEIBNER, Jürgen SCHIMMER

Patent number: 7878066Abstract: The invention relates to a vibration measurement system for frequency-selective oscillation measurement in particular of low frequencies as are relevant in the field of automation and drive technology. The invention proposes coupling a broadband transmitter structure, which is excited directly by the excitation signal to be determined, via an electrostatic or inductive force to a receiver structure. This force coupling results in amplitude modulation of a carrier signal exciting the receiver structure. The actual excitation signal can be extracted from the spectrum of the amplitude-modulated carrier signal, for example by suitably selecting the frequency of the carrier signal. In order to make an oscillation analysis possible which is as unsusceptible to interference possible, an interference signal brought about, for example, by connector excitations is largely eliminated in advance from the amplitude-modulated carrier signal.Type: GrantFiled: August 2, 2006Date of Patent: February 1, 2011Assignee: Siemens AktiengesellschaftInventors: Dirk Scheibner, Jens Makuth

Patent number: 7819012Abstract: A vibration measuring system for the frequency-selective measuring of especially low-frequency vibrations relevant in the area of automation and motive power engineering is disclosed which allows an economical vibration analysis of frequencies in the range of from 0 to 1 kHz. For this purpose, a broad-band transmitting structure which is directly induced by the excitation signal to be determined is coupled to a receiving structure by an electrostatic or inductive force. This force coupling brings about an amplitude modulation of a carrier signal inducing the receiving structure. The spectrum of the amplitude-modulated carrier signal can then be used to extract the actual excitation signal, e.g. by suitably choosing the frequency of the carrier signal.Type: GrantFiled: June 12, 2006Date of Patent: October 26, 2010Assignee: Siemens AktiengesellschaftInventors: Jan Mehner, Jens Makuth, Dirk Scheibner
