摘要:
For the homopolymerization of ethylene or for the copolymerization of ethylene with other 1-olefins, a catalyst is used which comprises a trialkylaluminum compound and the entire product from the reaction of a magnesium alkoxide which is dissolved, suspended or dispersed as a gel in an inert solvent, with a tetravalent transition-metal compound and an organoaluminum compound, washing with an inert solvent and reacting with a halogenated metal compound. A polymer having coarse particles and a high bulk density is obtained.

A method for determining a temperature of fuel in an injection system, in which the temperature of the fuel is ascertained as a function of a temperature of a coil of a metering unit of the injection system, a total resistance of the circuit of the metering unit being measured, and a proportion of a resistance of the coil in the total resistance of the circuit being calculated, and the temperature of the coil being calculated from the resistance of the coil.
摘要:
Method for wire-free transmission of data packets between network nodes in a control network, wherein the data packets each have a preamble for synchronization consisting of a predetermined number of preamble symbols, and wherein during a first operating mode, each preamble-subsymbol of a preamble symbol in the preamble is coded by the phase angle of a transmitted single signal pulse, during a second operating mode to increase the signal recognition performance, for the preamble which is transmitted in the data packet, a signal pulse sequence for coding the preamble-subsymbol is transmitted instead of a single signal pulse, where the single signal pulse within the signal pulse sequence is transmitted repeatedly.

A method for associating time slots with links between network nodes of a wireless interconnected network of a plurality of network nodes in which data are transmitted in the network on a time slot basis by association of the time slots to be used with the links on a plurality of channels, wherein a plurality of traffic requests each specifying a data transfer between a source node and a destination node are prescribed and set one or more time slot sequences that each describe a time-based sequence of time slots associated with links between adjacent network nodes of a transmission path between the source and destination nodes, and an association methodology for data transmission via a plurality of channels is determined, considering all predefined traffic requests, based on an optimization criterion, and configured such that the number of time slots used in the association methodology is as low as possible.
摘要:
An adjusting system of a motor vehicle for the adjustment of a closing part is disclosed. The system includesa first and second casing extending oblong in a length-wise direction. The second casing has a smaller cross section than the first casing and is arranged within the first casing to be adjustable in a length-wise direction. A spindle for the relative adjustment of a first casing to the second casing is included and arranged within either or both of the first and second casings.The system also includes an electromotor and a transmission connected with either or both of the spindle and second casing. In addition, at least one spring is arranged within either or both of the first and second casings and operates length-wise, such that one of the casings is attached on the side of the motor vehicle body and another of the casings is attached to the closing side.

A method establishes an IP-based communications connection between an electric vehicle and a charge control unit associated with a charging station assigned an IP address. The electric vehicle is connected to the charging station via a charging cable and/or an inductive charge coupling for charging and/or discharging. A first communication connection that can be used exclusively by the electric vehicle and the charging station is provided via the charging cable and/or the inductive charging coupling. The electric vehicle having the charging control unit and the charging infrastructure can communicate via a second communications connection that can be used in parallel by other electric vehicles and charge control units. An identification is provided to the electric vehicle and the charging control unit. An IP-based communication is established between the electric vehicle and the charging control unit, using the IP address.
摘要:
A method for monitoring a fuel temperature sensor over a repeating cycle includes: estimating a first value of a fuel temperature at the beginning of the cycle with the aid of a value of at least one further temperature from the same cycle and at least one of a second value of the fuel temperature and a further temperature from at least one previous cycle; and checking whether the deviation of a temperature of the fuel temperature sensor lies within a first range around the first value of the fuel temperature.
摘要:
An ultra-broadband signal having a plurality of pulses is transmitted from one or more transmitting nodes to one or more receiving nodes. In the ultra-broadband signal, data are transmitted by pulses having a first pulse rate in a first data transmission and by pulses having a second pulse rate in at least one second data transmission, with each second pulse rate higher than the first pulse rate. The pulses having the second pulse rate are transmitted in intervals, during which no pulses having the first pulse rate are transmitted. This has the advantage that by utilizing time gaps between pulses of the first data transmission, the data of a second data transmission can be transmitted at a higher pulse rate. The transmitting and receiving nodes need not be coordinated explicitly or coordinated from the outside.

摘要:
A method of associating time slots with a transmission path in a wireless interconnected network made of a plurality of network nodes such that the transmission path extends between a source node and a destination node and comprises a plurality of sequential links between adjacent network nodes, data being transmitted in the network on a time slot basis by the association of the time slots to be used with the links of the transmission path, wherein a quality value is determinable for each link within an association sequence of time slots describing an end-to-end data transmission from the source node to the destination node along the transmission path, where the value represents the reliability of the data transfer. An overall quality value for the association sequence can further be determined as a function of the quality values of each of the links.
