| 20090052643 | VOICE CONFERENCE APPARATUS, VOICE CONFERENCE SYSTEM AND METHOD FOR REALIZING A VOICE CONFERENCE - A voice conference apparatus consists of at least one base conference block having three or more signal ports, each including an input for a digitalized voice signal and an output for a digitalized voice signal, wherein a base conference block is configured such that, at a signal port, optionally a terminal or another base conference block may be coupled up using a coupler for the realization of a voice conference apparatus extended with respect to the number of participants or in terms of space, and wherein a base conference block is configured to enable a voice conference among the terminals or base conference blocks coupled thereto, and a remote coupler configured to couple a base conference block with at least one other spatially remote base conference block in order to enable a spatially extended voice conference. A voice conference system may be composed of at least two spatially separate voice conference apparatuses and is structured in a decentralized and modular way and is flexibly extensible. | 02-26-2009 |
| 20100093368 | Device and Method for Localizing Terminal Devices - When localizing terminal devices an updating measure of reference ambient information allocated to surroundings of the terminal device is executed when a deviation of ambient information determined by means of the terminal device from reference ambient information allocated to a position of the terminal device is detected. | 04-15-2010 |
| 20100097269 | CONCEPT FOR LOCALIZING A POSITION ON A PATH - An apparatus for localizing a position on a path, radio signals of fixedly positioned radio transmitters being receivable along the path, the apparatus including a determiner for determining properties of the radio signals of the fixedly positioned radio transmitters at the position, and a comparator for comparing the determined electromagnetic properties with previously recorded properties which characterize a reference path, and for determining a relation between the position and the reference path on the basis of a result of the comparison. | 04-22-2010 |
| 20100184457 | DEVICE FOR DETERMINING A DEVICE POSITION - A device for determining a device position, which includes a receiver for receiving signals of a plurality of transmitters and a determiner for determining reception powers of the signals of the plurality of transmitters. The device further includes a provider for providing transmitter positions of the transmitters on the basis of the signals of the plurality of transmitters. The device further includes a determiner for determining a first position of the device on the basis of the transmitter positions, wherein the determiner for determining the first position is further formed to determine transmitter directions on the basis of the first position and the transmitter positions, and to determine a second position of the device on the basis of the transmitter directions, the transmitter positions and the reception powers. | 07-22-2010 |
| 20100278079 | APPARATUS AND METHOD FOR DETERMINING A COINCIDENCE OF A POSITION WITH A REFERENCE POSITION - An apparatus for determining a coincidence of a position with a reference position, wherein radio signals from fixedly positioned radio transmitters can be received at the position, having a provider for providing properties of the radio signals of the fixedly positioned radio transmitters at the position, wherein the provided properties of the radio signals include transmitter identifications identifying the radio transmitters, a separator for separating the radio transmitters into a first number of radio transmitters previously recorded transmitter identifications of which at the reference position are identical with transmitter identifications provided at the position, and into a second number of radio transmitters previously recorded transmitter identifications of which at the reference position and transmitter identifications provided at the position are different, and a determiner for determining a measure of matching for the position on the basis of the provided properties of the radio signals, wherein both properties of the first number of radio transmitters and properties of the second number of radio transmitters are taken into account in the determination of a measure of matching, and wherein the properties of the first number of radio transmitters and the properties of the second number of radio transmitters enter the measure of matching differently. | 11-04-2010 |
| 20100305851 | DEVICE AND METHOD FOR UPDATING CARTOGRAPHIC DATA - A device for updating cartographic data for a predetermined region, having a collector for collecting location information of a path covered in the predetermined region, an overlayer for overlaying the collected location information with the cartographic data for the predetermined region, a determiner for determining portions contradictory or missing in the cartographic data for the predetermined region on the basis of the overlaid collected location information, and an updater for updating the cartographic data in the missing or contradictory portions on the basis of the overlaid collected location information. | 12-02-2010 |
| 20110153632 | APPARATUS AND METHOD FOR ALLOCATING A CURRENT MEASUREMENT VALUE FOR A GEOGRAPHICAL POSITION TO A MAP OBJECT - An apparatus for allocating a current measurement value for a geographical position to a map object of a geographical map, wherein the current measurement value originates from a series of adjacent measurement values for adjacent geographical positions, having a processor for determining a first probability measure indicating whether the current measurement value can be allocated to a first map object to which at least one adjacent measurement value of the series has already been allocated previously, and for determining a second probability measure indicating whether the current measurement value can be allocated to a second map object having an intersection with the first map object, if the first probability measure indicates that an allocation of the current measurement value to the first map object is unlikely. | 06-23-2011 |
