20100124190 | METHOD FOR OPERATING A WIRELESS INTERCONNECTED DATA NETWORK WITH A PLURALITY OF NETWORK NODES, AND NETWORK NODES - A method is described for operating a wireless interconnected data network with a plurality of network nodes (MP | 05-20-2010 |
20110194415 | METHOD FOR OPERATING A MESH-TYPE NETWORK, PARTICULARLY AS DEFINED IN AN IEEE 802.11S STANDARD, FORMED BY A PLURALITY OF NETWORK NODES - The invention relates to a method for operating a mesh-type network, particularly as defined in an IEEE 802.11s standard, formed by a plurality of network nodes, said network operating at least a first network node that functions as access point for stations which are dissociated from the network and a second network node that functions as connector point for stations that are dissociated from the network. When switching a dissociated station from a radio service area of the first network node to the radio service area of the second network node in said mesh network, an updating of allocation information of nodes based on a routing failure message which is defined according to a routing protocole valid for the mesh network is carried out. | 08-11-2011 |
20140298427 | METHOD AND NETWORK NODE DEVICE FOR RUNNING PUSH-BUTTON CONFIGURATION SESSIONS WITHIN HETEROGENEOUS NETWORK AND HETEROGENEOUS NETWORK - A heterogeneous home network (with possibly multiple hops between devices) uses a push button configuration mechanism that ensures only one single new network node device is registered for a single push button key press event and overlapping Push-Button Configuration sessions within the heterogeneous network are prevented by an enhanced mechanism for running Push Button Configuration sessions based on a Push-Button Configuration handshake procedure triggered and initiated by a virtual or physical Push-Button-Event on a new device, which wants to join the heterogeneous network for a user friendly security bootstrapping, in which multiple network node devices in the heterogeneous network belonging already to the heterogeneous network are involved in registering the new device. The Push-Button Configuration handshake procedure is initiated to get a permission information to join the network or to proceed with the Push-Button Configuration or to get a rejection information not to join the network. | 10-02-2014 |
20140337952 | METHOD AND DEVICES FOR RUNNING PUSH-BUTTON CONFIGURATION SESSIONS - A method and a network node device run Push-Button Configuration sessions within a heterogeneous network, IEEE 1905.1, using a push button configuration mechanism that ensures that only one single new network node device is registered for a single push button key press event and thus overlapping Push-Button Configuration sessions within a heterogeneous network are prevented. After finishing the push button configuration mode, the number of new nodes is checked. If more than one node has been added, a configuration roll-back is performed. Preferably, the push button configuration roll-back is performed as soon as the authentication of more than one distinct node has been detected. The roll-back includes the deletion or deactivation of credentials established by the push-button configuration. | 11-13-2014 |
20150052357 | METHOD AND NETWORK NODE DEVICE FOR CONTROLLING THE RUN OF TECHNOLOGY SPECIFIC PUSH-BUTTON CONFIGURATION SESSIONS WITHIN A HETEROGENEOUS OR HOMOGENOUS WIRELESS NETWORK AND HETEROGENEOUS OR HOMOGENOUS WIRELESS NETWORK - A method and network node device control the run of technology specific Push-Button Configuration sessions within a heterogeneous or homogeneous wireless network as well as a heterogeneous or homogeneous wireless network detecting a session overlap within the network. The session is related to a configuration session (bootstrapping session, setup session) that establishes a security configuration for encrypted communication over a wireless link it is proposed an enhanced mechanism for controlling the run of technology specific Push Button Configuration sessions within a heterogeneous or homogeneous wireless network and a plurality of network node devices interconnected to each other via at least one interface and/or over multiple hops and authenticated or unauthenticated for the network by using a piece of information, e.g. a “Configuration Setup Session Identifier (CSSID),” for identifying a technology specific Push Button Configuration setup session. | 02-19-2015 |

20120020336 | Method For Data Transmission In A Local Area Network - A method for data transmission in a local area network, wherein data is transmitted on a medium access control layer within successive time frames between a plurality of first nodes comprising client nodes and a second node within reach of the first nodes, and a coordinator node for the first nodes where a time frame comprises a plurality of time slots. Each time slot is assigned to a first node that is a slot owner node being exclusively allowed to start transmitting data at a time within a first interval at the beginning of the time slot. At least one first nodes of the plurality of first nodes is allowed to use the time slot based on a contention based access to transmit the data in a second interval succeeding the first interval where the slot owner node has not started transmitting data at a time within the first interval. | 01-26-2012 |
20120182943 | Method for Establishing a Bidirectional Communication Path in a Wireless Network - A method for establishing a bidirectional communication path in a wireless network, where the network includes nodes comprising a sink node and a plurality of subscriber nodes, and where the communication path for the bidirectional transmission of data packets is to be established between the sink node and at least one queried node of the subscriber nodes. An uplink path from a particular subscriber node to the sink node is determined by periodically exchanging path messages between adjacent nodes of the network, where a particular path message signals the respectively shortest distance to the sink node, i.e., as a metric. A downlink path from the sink node to the at least one queried node is determined by inserting an address list into at least one of the path messages sent by the sink node, which list comprises the address of a respectively queried node. | 07-19-2012 |
20140028742 | METHOD AND DEVICE FOR OPTICAL FOCUSING - A device for optically focusing a projection image projected by a projector includes a detector for controlled creation of at least one observation shot of the projection image over a time period, a processing unit for defining at least one image section within the projection image generated by the projector, where the image section is modulated over the time period with respect to the optical power and/or the optical spectrum thereof, and the at least one image section of the projection image is essentially synchronous compared with the corresponding respective image section of the observation shot, where the processing unit also calculates a variable derived from the comparison of the respective image sections and a control signal derived from the derived variable, and outputs the control signal to a focusing device of the projector. | 01-30-2014 |
