Gear wheels at opposite ends of the pull rod mesh with the teeth in the guide rails. The pull rod has a gear drive which rotatably couples the gear wheels together.

Abstract: Systems and methods for adding services to an application platform via an extension platform coupled to the application platform. The application platform runs in a first operation system process and provides a number of resources. The extension platform is implemented in a second operation system process and communicates with the application platforms via standard inter-process communication protocols. The extension platform provides an environment to dynamically model and host application services. A resource abstraction layer provides the extension platform with access to the resources provided at the application platform. The resources are utilized by the extension platform to design and to execute the application services. The application services hosted in the extension platform are centrally managed and administered from the application platform via exposed interfaces.

Abstract: According to the invention, a power characteristic information concerning a power characteristic profile of a target terminal is transmitted to a base terminal, before transferring signaling of a connection set up from a base terminal to a target terminal. As a result of the connection set up signaling, a power characteristic request is transferred based on the power characteristic information.

Abstract: A network access device checks communication data flows coming into a network for specific authorization information. The quality of service class (QOS) with which a flow is retransmitted from the network access device through the network is determined by the result of the check. Each end device that transmits a flow to the network access device can first request authorization for the flow from a gate keeper and resource manager mechanism of the network. The mechanism returns specific authorization information which the end device includes in the flow before the flow is transmitted to the network access device. In one embodiment, only if an incoming flow is determined to have the specific authorization information will the network access device allow the flow to be retransmitted through the network with a particular quality of service (QOS) class.

Abstract: In order to transmit data packets between a wirelessly connectable communications device and a communications partner, particularly during a handover process, the invention provides that when a first wireless transmission path is available, an availability of at least one additional wireless transmission path is detected. Based on the detection, a specific assignment schema, via which at least one portion of the data packets is assigned to each of the transmission paths, is selected according to specific transmission requirements and/or to a transmission protocol to be used for transmitting the data packets. An address specification specific to the transmission path is then assigned to a respective data packet that is assigned to a transmission path. By using the assigned address specifications, the data packets are transmitted via the different transmission paths between the communications device and the communications partner according to the selected assignment schema.

Abstract: Transmission resources of one or more individual transmission links, especially of individual transmission bottlenecks, are managed by a resource manager. In the course of a setting up of a connection, the resource manager determines, by using an item of connection information, the origin and destination of the connection to be set up, and identifies whether this connection is routed over a particular transmission link. Based on the result of the determination, a message is subsequently generated and transmitted to the origin of the connection. A selection of transmission resources to be used for the connection is then carried out based on the transmitted message.

Abstract: A method for packet-oriented transmission of speech, audio, video and/or useful data between an internal and a public data network by means of a pre-reservation of NAT addresses. A pre-NAT address is allocated to the IP address of an internal computer by an NAT address server. The relevant allocation data set is available in a NAT host 200 which acts as a gateway between the internal and the public data network; whereby single addresses (pre-NAT addresses) are provided for transparent use of the data packet in the internal and public network when the information on the origin or destination in an IP Header or in the protocol data, in addition to the information on origin or destination in said header, is modi.

Abstract: A method establishes a connection between a source network with a source network resource manager and a target network with a target network resource manager. According to the method, a connection control unit of the source network transmits a connection establishment signal to a connection control unit of the target network and—parallel to this—a reservation request to the target network resource manager. The target network resource reserves the requested resources and forwards the reservation request towards the target network resource manager, which also reserves the requested resources and transmits reservation information regarding the success of the resource reservations to the connection control unit of the target network.

Abstract: The method is essentially carried out by a gateway device, which is logically divided up into a gateway controller and one or, if required, more user data gateways. Quality of service signaling is evaluated by the gateway controller and, depending thereon, quality of service information is transferred to a user data gateway. Specific quality of service properties of connection segments coming into and/or going out from the user data gateway are evaluated by the user data gateway and, depending thereon, a quality of service setting is carried out according to the transferred quality of service information.

Abstract: The invention relates to a method for determining a characteristic of a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto, said characteristic being determined from measured values of the at least one measuring sensor and of the at least one reference sensor. It is proposed to record a characteristic point during continuous measurement operation, starting with the first time the sensor arrangement is put into operation, when a definable measurement point is reached in the process for the first time, if the changes in measured value in the variation over time of the at least one measuring sensor and in the variation over time of the at least one reference sensor remain within a definable tolerance band within a definable time interval.

Abstract: A method is disclosed for operating a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto, with a characteristic of the sensor arrangement being recorded in an initialization phase from measured values of the at least one measuring sensor and of the at least one reference sensor, and an alarm being given during continuous operation if the deviation from the characteristic lies outside a tolerance band. It is proposed to suspend the alarm dynamically so long as the changes in the measured value in the variation over time of the at least one measuring sensor or in the variation over time of the at least one reference sensor differ by more than a definable limit within a definable time interval.

Abstract: Transmission resources are controlled in individual transmission paths in a packet-oriented communication network, whereby data-packet address information which identifies the origin and the goal of the data packets, is transmitted to a resource manager, responsible for a transmission path, from a network transmission device. On a resource request, for a connection to be subsequently generated, the origin and goal thereof are compared with the origin and goal of the previously transmitted data packets by the resource manager. Should there be agreement, the resource manager can deduce that the connection to be established can equally run over the corresponding transmission path. Correspondingly, establishment of further connections occurs, depending upon the available resources of the transmission path.
