Abstract: The present embodiments relate to providing near real-time communications from a public network to a private network. A first computing device in a public network can obtain data packets to be provided to the private network from an application executing on the first computing device. A trust module executed by the first computing device can authenticate the user, application, and the data packets to be provided to the private network and add metadata relating to the sending user, recipient user, etc. The data packets can be forwarded to the private network via a cross-domain system (CDS). The metadata and the digital signature on the data packets can be verified by a trust module executing on a second computing device in the private network. The second computing device can receive the data packets and store the data packets for subsequent actions to be performed in the private network.

Abstract: Voice command matching during testing of voice-assisted application prototypes for languages with non-phonetic alphabets is described. A visual page of an application prototype is displayed during a testing phase of the application prototype. A speech-to-text service converts a non-phonetic voice command spoken in a language with a non-phonetic alphabet, captured by at least one microphone during the testing phase of the application prototype, into a non-phonetic text string in the non-phonetic alphabet of the voice command. A phonetic language translator translates the non-phonetic text string of the voice command into a phonetic text string in a phonetic alphabet of the voice command. A comparison module compares the phonetic text string of the voice command to phonetic text strings in the phonetic alphabet of stored voice commands associated with the application prototype to identify a matching voice command. A performance module performs an action associated with the matching voice command.

Abstract: A hydrogen fuel cell vehicle system and method inhibit formation of black ice on road surfaces at low temperatures as a result of exhaust water by treating the exhaust water prior to discharge with a deicing or antifreeze substance to lower the freezing point of the water. A metering device may meter a deicing or antifreeze substance, such as sodium chloride, calcium chloride, urea, or the like to be dissolved in the exhaust water that is produced during the production of energy. The vehicle may include a bypass valve that selectively bypasses the water treatment system when ambient conditions are not conducive to ice formation. The bypass valve is operated to direct exhaust flow to a condenser and water treatment system when ambient conditions are favorable to ice formation, with the deicing or antifreeze substance metered based on current or predicted ambient or road surface conditions.

Abstract: A method for determining a flow speed of a liquid in a fluid conduit is provided. During a signal-generating phase, an impulse signal is applied to a first ultrasonic transducer. A response signal is then received at a second ultrasonic transducer. A measuring signal is later derived from the response signal, wherein the derivation comprises reversing a signal portion with respect to time. During a measurement phase, a liquid moves with respect to the fluid conduit. The measuring signal is then applied to one of the two transducers and a response signal of the measuring signal is measured at the other transducer. A flow speed is derived from the response signal of the measuring signal.

Abstract: For providing system services reliably for an energy supply network, measured values indicating an electrical state of the supply network and/or of a distribution network are recorded. A deviation of the operational state of the supply network from a required operational state is determined and control measures are defined for restoring the required operational state. Control data which indicate a part of the control measures to be carried out by devices of the distribution network are transmitted to the control device, and control commands are determined for the devices of the distribution network with which the devices are controlled such that the distribution network carries out the required control measures. Estimated control data are defined and the communication connection to a network controller is monitored. In the event of a fault in the communication connection, the control commands are defined using the estimated control data instead of the control data.
