Abstract:
Process for operating a high temperature fuel cell stack by the steps of: connecting the fuel cell stack in parallel to a power supply unit at a predefined temperature and/or voltage of the fuel cell stack, applying a voltage from the power supply unit of between 700 to 1500 mV per fuel cell across the fuel cell stack irrespective of the electro-motive force of the fuel cell stack, heating up the fuel cell stack from the predefined temperature to operation temperature while maintaining the voltage per fuel cell the power supply unit, maintaining the fuel cell stack at or above a predetermined operation temperature and/or above a predetermined voltage until the fuel cell stack is to be put into operation, supplying fuel to the fuel cell stack, and disconnecting the power supply unit followed by connecting a power-requiring load to the fuel cell stack.
Abstract:
An alternative access point for M2ME's is provided by introducing an extended M2ME, a M2ME/Femto, which is able to operate as a Femto cell in addition to operating as an M2ME is provided. The M2ME/Femto is configured to recognize a connectivity disruption in a conventional wireless connection to a home operator and to respond to such a disruption by providing for an alternative, fixed connection between the M2ME/Femto and the home operator. A M2ME configured to access the M2ME/Femto when required due to a connectivity disruption and a node of a home operator configured to set up an alternative fixed connection between the M2ME/Femto and the node when required due to a connectivity disruption at the wireless connection is also provided.
Abstract:
The present invention generally relates to a gateway, a method for controlling the gateway, an application server, and a method for controlling the application server. The present invention particularly relates, but is not limited to, a technology that facilitates the formation of a single network from a plurality of local networks.
Abstract:
This invention relates to methods and apparatuses for implementing remote provisioning of a downloadable identity module into one of several Trusted Environments (7) available at a mobile device (1). A server (2) performs a selection of one of the Trusted Environments (7) available at the mobile device (1) for which at least one of one or more home operators (3) can provide downloadable identity modules, selects one of the one or more home operators (3) which can provide downloadable identity modules for the selected Trusted Environment, and manages the provisioning of a downloadable identity module to the mobile device (1).
Abstract:
The present invention relates to auto-provisioning of authentication data for client devices. A registration server includes a gateway determination unit, which is configured to determine a gateway apparatus transferring a request signal from a device, and a processing unit. The processing unit is configured to transmit a first signal including a token and first access information of the gateway apparatus to the device if an identifier of the gateway apparatus is stored on the server, and to transmit a second signal indicating a positive response to the gateway apparatus when it obtains the token and the identifier based on a third signal received in response to the first signal. The gateway apparatus sends the secret value to the device when it receives the second signal.
Abstract:
There is provided a method in a node of a communication network. The method comprises establishing communication with a device, selecting a message according to a node profile, sending the selected message to the device; and updating the node profile according to the behavior of the device.
Abstract:
A mediation server which is able to communicate with a plurality of account managing servers (104) and mediates requests for issuing subscription information transmitted from a plurality of communication devices between each communication device and any one of the plurality of account managing servers (104), the mediation server comprising, a selection unit configured to select the account managing server to which the request is to be transmitted based on information regarding a current operational status of each account managing server stored in a database, when the request is received from the communication device, and a transmission unit configured to transmit the request for issuing the subscription information to the selected account managing server.
Abstract:
Process for operating a high temperature fuel cell stack, the process comprising the following steps: b) connecting the fuel cell stack in parallel to a power supply unit at a predefined temperature and/or voltage of the fuel cell stack, h) applying a voltage from the power supply unit of between 700 to 1500 mV per fuel cell across the fuel cell stack irrespective of the electro-motive force of the fuel cell stack, i) heating up the fuel cell stack from the predefined temperature to operation temperature while maintaining the voltage per fuel cell the power supply unit, j) maintaining the fuel cell stack at or above a predetermined operation temperature and/or above a predetermined voltage until the fuel cell stack is to be put into operation, k) supplying fuel to the fuel cell stack, l) disconnecting the power supply unit followed by m) connecting a power-requiring load to the fuel cell stack.
Abstract:
A method and arrangement for supporting network searches for information or content using one or more web-based search engines. When a search query is received (1:2) from a terminal user (A), a refined search query is created (1:4) from the received query based on a user profile (104) of the user. A network search is then made (1:5) in at least one search engine (106) using the refined search query. An aggregated search result from said network search is finally delivered (1:6) in response to the received search query.
Abstract:
A method is provided which enables ratings data registered by a number of users for a first service and at least one corresponding service to be collected, wherein each user have been federated for a Single-Sign-On (SSO) on the first service as well as on the corresponding service/s. In response to a request for a set of ratings data received from a user requesting for the first service, a group of users is identified and the SSO identity of each SSO federated user of the identified group of users is mapped to one or more service identities of the respective SSO federated user. The mapping enables ratings data associated with the SSO users of the identified group of SSO users to be collected and normalized, such that the requested ratings data can then be provided to the requesting user in a unified format.
