  • Patent number: 7184779
    Abstract: A method as well as a system are described for determining the travel time of at least one mobile user end device between a starting point (A) and an end point (E) that is spatially separated from it. To this end, specific pieces of information of at least one mobile user end device located at the starting point (A) and at the end point (E) are determined and each linked to a time marker. The specific pieces of information of the mobile user end devices are compared with one another electronically in at least one central processing unit. When the specific pieces of information of a mobile user end device are in agreement at the starting point (A) as well as at the end point (E), the time difference between the time markers is formed electronically in the central processing unit and the travel times are determined therefrom.

  • Patent number: 7162251
    Abstract: The invention relates to a method for acquiring traffic situation data in a network of traffic routes which is covered by a cellular mobile radio network comprising a multiplicity of base stations and in which a multiplicity of vehicles is moving which are in each case provided with an operating mobile terminal for the mobile radio network. In this method, characteristic patterns of values (called signal transit times in the text which follows), which are representative of the signal transit times with respect to the respective base station during the movement of a terminal along the course of the respective traffic route, are determined and permanently stored at least for some of the individual traffic routes of the network of traffic routes at least for selected base stations, the respective characteristic pattern or a sequence of values representative of this pattern is mapped onto the course of the respective traffic route (calibration).

  • Publication number: 20030152047
    Abstract: The invention relates to a method for detecting travel information in a traffic network covered by a cellular mobile radio network with a plurality of base stations provided with a clear identifier and wherein a plurality of vehicles move, said vehicles being respectively provided with an operating mobile terminal for the mobile radio network. Information on the contact between the end terminals and the base stations is used to estimate the location of the terminals. At least for one part of the traffic network, wherein the base stations have a transmission range with a cell radius corresponding to the distance separating neighboring traffic routes, characteristic models are determined in the form of sequences of identifiers of said base stations with which a terminal respectively enters into contact when it is displaced along a route, allocated to the respective route and permanently stored.

  • Patent number: 6252890
    Abstract: An apparatus transmits digital signals between a higher-ranking station and one or more subordinate stations through transmission devices. A signal transit time is automatically measured in the transmission devices, differences in transit time are automatically compensated for and useful signals in the various subordinate stations are automatically synchronized with one another.

  • Patent number: 6104844
    Abstract: An image sensor has an optical configuration for imaging an image to be recorded onto sensor elements. The sensor elements have dimensions below a resolution of the optical configuration. Neighboring sensor elements are in each case combined into pixel sensor regions. During the recording of the image, the measured values X of the sensor elements of each sensor region are averaged. In this case, each average value corresponds to a pixel of the recorded image. In this manner, production-dictated tolerances of the sensor elements are compensated for by the averaging.

  • Patent number: 5940386
    Abstract: A transmission system includes a central station, a counterpart station and at least two base stations connected to the central station through at least one interface. The base stations wirelessly exchange signals with at least one mobile terminal station. At least one Uko standard interface is expanded by a device for transmitting and delaying synchronizing signals, in such a way that a transmission of the at least one Uko interface that is synchronized with the other interfaces is attained.

  • Patent number: 5903567
    Abstract: A method of data transmission for transmitting by a clocked transmission device discretized data incorporated in block form into a frame structure, the amount of data grouped together respectively in a block being variable and the clock frequency of the transmission device being changed according to this amount of data in such a way that the frame structure and frame length are maintained.

  • Patent number: 5864581
    Abstract: A signal transmission apparatus includes a higher-level station, a lower-level station and a digital transmission device connected between the stations and having a signal transit time to be measured. Each of the stations has a transmitter for sending useful signals, each clocked by a respective clock signal, through the transmission device to other station. Each of the stations has a receiver for receiving the useful signals clocked by the other station and for separating out the clock signal superimposed on the applicable useful signal. The useful signal to be transmitted in the higher-level station is clocked by a given clock signal. The useful signal to be transmitted in the lower-level station is clocked by a clock signal derived from the clock signal separated out from the receiver of the lower-level station.

  • Patent number: 5844904
    Abstract: A digital message switching system includes at least one digital message switching unit and a plurality of subordinate units each being coupled to the respective switching unit through a respective transmission link. In order to signal a request of a subordinate unit to transmit, that unit first sends at least one message of meaningless content to a higher-ranking unit and only then sends messages of meaningful content.

  • Patent number: 5572107
    Abstract: A switched capacitor network includes a first capacitor being charged and discharged in alternation by a first switch device and being connected to a first voltage source for charging. A second capacitor is charged and discharged by the second switch device in synchronism with the first capacitor and is switched between the first voltage source and the second voltage source for charging. A product of the capacitance of the first capacitor and the voltage of the first voltage source is equal to a product of the capacitance of the second capacitor and a voltage difference between the two voltage sources. A product of the capacitance of the first capacitor and a contact resistance of the first switch device in a supply line path thereof, is equal to a product of the capacitance of the second capacitor and a sum of an internal resistance of the second voltage source and a contact resistance of the second switch device in a supply line path of the second capacitor.

  • Patent number: 5557187
    Abstract: A switched capacitor network includes a switch device alternatingly charging two first capacitors having the same capacitance from a signal voltage source with polarities being opposite relative to a ground potential and then discharging each of the two first capacitors through the input circuit of a respective differential amplifier.
