Abstract: A system and method for remote control of functionalities of a vehicle, for example a motor vehicle reserved for hire, is provided. The system and method include transmission and receipt of information between a mobile terminal, a remote vehicle management system and a control unit of a vehicle to remotely control, particularly to remotely initiate, particular functionalities of a vehicle which has been selected, particularly reserved, in advance using the vehicle management system. The mobile terminal is identified to the vehicle on the basis of an interchange of identifiers that the vehicle and the terminal have received in advance from the vehicle management system.

Abstract: A method for resource management in a vehicle-based mobile communications unit. In the method, during a mobile communication transaction conducted via two simultaneously established mobile communication channels, the user-nonspecific data components of the currently active identity profile are compared with one another to determine the mobile communication services provider currently being used. In case of a mobile communication services provider identity determined within the context of the comparison, one of the mobile communication channels is switched off and the mobile communications are conducted via the other mobile communication channel.

Abstract: An aircraft is provided, which comprises a support structure and at least four lift rotors. Each of the lift rotors is attached to the support structure and comprises at least one propeller. The lift rotors are constituted such that a rotational plane, in which the at least one propeller of the lift rotor rotates, is tilted with respect to a plane formed by the support structure.

Abstract: A method is provided for roaming management in a mobile radio unit, in the memory of which a plurality of different individually activatable identity profiles are stored. The identity profiles includes different options for the mobile radio unit to access different mobile radio networks. In the method, the suitability of a currently active identity profile is automatically verified according to predefined rules and taking into account the current position of the mobile radio unit, and a decision is made as to whether a switch to a currently inactive identity profile should be made. An estimated destination of the mobile radio unit is additionally taken into account when making a decision about switching profiles.

Abstract: An electrical charging apparatus (10) for charging an electrical energy store of a motor vehicle (12) has an electrical connection (16) to electrically connect the charging apparatus (10) to a charging station (14) and to interchange electrical energy with the charging station (14). An electrical converter (18) is connected to the electrical connection (16) to interchange the electrical energy with the charging station (14) via the electrical connection (16) and to convert the electrical energy. A control unit (20) is connected to the electrical converter (18) to control the interchange of the electrical energy. A communication interface (22) is assigned to the control unit (20) and is designed to interchange data (34) with the charging station (14). The control unit (20) is designed to control the interchange of the electrical energy on the basis of the data.

Abstract: A charging plug (10) for an electric vehicle having has contact pins (L1, N, PE) for establishing a plug connection to a coupling, and temperature sensors (NTC1, NTC2, NTC3) that are coupled thermally to the contact pins (L1, N, PE) for detecting a temperature profile between the charging plug (10) and the coupling.

Abstract: A method for operating a hybrid vehicle having an internal combustion engine and an electric machine, wherein the hybrid vehicle can be driven purely electrically if the internal combustion engine fails because, for example, a fuel tank for supplying the internal combustion engine with fuel is empty. In the event of failure of the internal combustion engine, continued purely electric travel of the hybrid vehicle is made possible only on condition that a restart of the hybrid vehicle is initiated.

Abstract: The present invention relates to a process for preparing methacrylic acid based on the hydrolysis of methacrylic esters.

Abstract: A communication device for a vehicle has a programmable memory circuit into which access data of a service provider is programmed for the purpose of establishing communication via one of the communication channels provided by the service provider. The communication device has a transmission and/or receiving device to transmit and receive data via the communication channel. Access data of the service provider intended to be programmed into the programmable memory circuit is received by the transmission and/or receiving device, and made available by the same for the purpose of being programmed into the programmable memory circuit.

Abstract: A lubrication system for a wind turbine having a control system, the lubrication system including a sump configured to collect a lubrication fluid, and at least one heating unit configured to heat the lubrication fluid based on at least one forecasted condition.

Abstract: A guide device for an endless torque-transmitting member. The guide device includes at least two corresponding guide tongues between which the endless torque-transmitting member is at least partially guided. The guide tongues are held at a predetermined distance from each other by a connection region. The distance between the guide tongues is maintained substantially constant when there is a temperature change by the use in the guide device of materials having different coefficients of thermal expansion. A mold for producing a guide device is disclosed and includes two corresponding mold halves, where at least one connecting component formed from a material having a lower coefficient of thermal expansion than that of the guide tongues is held in one mold half.

Abstract: The present invention relates to a process for preparing hydrogen cyanide by the Andrussow process by reacting methane-containing gas, ammonia and oxygen-containing gas over a catalyst at elevated temperature, wherein the proportion by volume of oxygen in relation to the total volume of nitrogen and oxygen (O2/(O2+N2)) is in the range of 0.2 to 1.0 and the reaction is performed with a non-ignitable reactant gas mixture.

Abstract: An on-chip micro-fluidic device (10) fabricated using a semiconductor material. The device has a micro-fluidic channel or chamber (14) defined within the material and one or more monolithically integrated semiconductor lasers (12) operate to form an optical trap in the channel or chamber (14).

Abstract: In an OFDM system the same Walsh code is used at the same time for a plurality of transmitters. The multiple transmitters can be from the same, or different devices (e.g., different base stations on the downlink, different terminals on the uplink). Each subcarrier/antenna combination will share a similar pilot Walsh code, except for the fact that the scrambled spread pilot signals will be phase shifted on some subcarriers of some antennas, based on the subcarrier/antenna combination.

Abstract: A method for detecting a presence of an excess delay spread within a received signal is provided. First, a quantitative estimation of a similarity of two segments of the received signal is performed. Thereafter, the presence of the excess delay spread within the received signal based upon the quantitative estimation is determined. In determining the presence of an excess delay spread, the quantitative estimation can be compared to a detection threshold.
