  • Patent number: 11044231
    Abstract: An assembly checks at least one firewall device and a method protects at least one data receiver. In the method, permissible and non-permissible data traffic is differentiated in data traffic in the direction of the data receiver using specific rules. Non-permissible data traffic is blocked, and permissible data traffic is allowed through. In order to check the function of the firewall device, the data traffic which has been allowed through is interrupted if the data traffic which has been allowed through has non-permissible data traffic.

  • Publication number: 20200326249
    Abstract: A capacitive multipath force sensor module includes a movable actuator, first and second stationary capacitor plates, and a central capacitor plate connected to the actuator and positioned between the stationary plates. The central plate moves by a same amount toward one stationary plate and away from the other stationary plate when the actuator is moved. In multiple successive cycles, while the first stationary plate is held at ground, (i) the central plate and the second stationary plate are connected to a voltage and (ii) are then disconnected from the voltage with the central plate being connected to a capacitor having a known capacitance value to thereby enable a charge quantity stored on the central plate to be transferred to the capacitor. After a predefined number of cycles, a voltage of the capacitor, which is indicative of an amount of movement of the actuator, is measured.

  • Publication number: 20200322236
    Abstract: A method and transmission apparatus for direct and feedback-free transmission of log messages from at least one first network into a second network is provided. Log messages are transmitted individually and directly. The log messages in the first network are monitored by a monitoring device and transmitted into the second network via a one-way data transmission unit. The transmission is thus carried out feedback-free and with integrity protected. Additionally, a log server having a line loop is provided. Local messages are transmitted via the line loop and filtered, monitored by a monitoring device and transmitted directly to a second log server in the second network via the one-way data transmission unit Thus, efficient transmission of log messages into a second network for real-time analysis is achieved.

  • Publication number: 20190291756
    Abstract: A method for supplying power to railway operating elements that are arranged along a railway line. A terminal station has a power supply device. At least one substation has a power supply subunit for at least one connected railway operating element. An input-side control unit of the substation modifies the current consumption in the substation incrementally, with corresponding modification of the voltage of the power supply subunit to match the rated voltage of the railway operating element on the substation, and producing a coded message. The control device of the terminal station modifies the output voltage according to the coded message, until the rated voltage for the railway operating element is reached on the power supply subunit. When the nominal voltage is reached the power supply subunit is connected to the railway operating element.

  • Patent number: 7225168
    Abstract: The present invention provides an efficient and simple method and system for providing a customer with a service on demand. The invention is based on providing a plurality of interconnected technical devices with remote access. During operation of a technical installation including the technical devices, operating data are acquired, encrypted and stored in a operation database. Upon an explicit service request by the customer, at least one of the technical devices sets up a remote connection to a service center, preferably by using a smart card including Public Key Infrastructure (PKI) data for validating the smart card, where the remote connection is verified and the encrypted data stored in the operation database are read out and decrypted. Based on the decrypted data—which represent a current status of the technical installation—, a service activity is efficiently performed at the technical installation, either remotely or locally.
