A coupler includes one or more pairs of ears each having an orifice, a lever having one end engaged between the ears and having an aperture aligned with the orifices of the ears for receiving a locking pin. The locking pin includes a head formed on one end and having an inner flat peripheral surface for solidly engaging with the ears, and includes an opening formed in a peripheral wall which may be expanded radially outward to engage with the ears, for solidly securing the locking pin to the ears. A retaining ring may solidly secure the locking pin to the ears.

The invention is directed towards a function activity handling arrangement for provision in a building as well as a method, computer program and computer program product for performing an activity of a function in a building. The arrangement comprises a wallpaper (10, 3, 14) with a group of embedded electrical wires. The arrangement may also comprise a user input detector (18) equipped with a wire connector for connection to the wire group, a pulse providing unit sending electric pulses to the wire group, a pulse response detecting unit detecting a group of response signals corresponding to the sent pulses and a pulse response analyzing unit that compares the response signal group with a set of response patterns and provides, if the detected response signal group matches a response pattern, user input data for a corresponding function.

A method and apparatus for providing connectivity with a public communication services network (204) for a mobile terminal (200). A temporary connectivity identity and associated security parameters are obtained from the network (2:1) and loaded into the mobile terminal from a connectivity providing unit (202) over a local communication link (2:2). When the mobile terminal (2:3) later sends an access request to the network including the temporary connectivity identity, the mobile terminal is registered with the network based on the temporary connectivity identity and associated security parameters. If the network can validate the temporary connectivity identity by means of the associated security parameters (2:5), a connection can be set up with the mobile terminal (2:6) for communication services in the network.

The present invention relates to a nodes and methods for use in a Universal Plug and Play (UPnP) system to provide support for both UPnP security and mobility of security aware UPnP nodes. A gateway is arranged to provide remote access to a UPnP network to remote UPnP nodes via the gateway. The gateway comprises means for creating a virtual UPnP node for emulating internal presence of a remote UPnP node on the UPnP network. The virtual UPnP node is arranged to obtain and store security information associated with the remote UPnP node. The security information specifies how the remote UPnP node is authorized to interact with other UPnP nodes in the UPnP network. The security information may be used to filter messages from the UPnP network to the remote UPnP node.

An improved structure of three-dimensional (3D) spectacles is provided, including a spectacle frame on which an RFID (Radio Frequency Identification) chip is mounted. The 3D spectacles are specifically for use in a 3D auditorium or 3D theater and are composed of a frame, lenses, and temples. The RFID chip is combined with the spectacle frame by being embedded in the frame or attached to a surface of the frame. With the RFID chip so mounted, a theater worker may use a reader to identify if a specific pair of 3D spectacles has already been sanitized. Also, the 3D spectacles can help in entrance and exit management, ticketing management, distribution of souvenirs, and toilet guiding service. In file-out, a reader may be used to confirm the returning of 3D spectacles. In this way, the theater service quality can be significantly improved.

A sensor data system, method and computer program configured to handle sensor data are disclosed. The system includes a reception unit adapted to receive sensor data, a storing unit adapted to store at least some of the received sensor data in an observations database, a recording unit adapted to record usage of the sensor data, and a relevance determination unit adapted to determine the relevance of the sensor data based on the recorded usage. A decision unit is adapted to remove excess sensor data with determined relevance below a limit from the observations database, and to retain relevant sensor data with determined relevance above the limit in the sensor database. Sensor data in an observations database may thereby be limited to a desired size, by removal of excess sensor data from the database.
摘要:
Method and sensor observation system (200), for reporting observations to data users (204) based on sensor data collected (2:1) from a network of sensors (202). A first observation report that originates from a sensor in the network, is provided (2:4) to a first data user and a rating with respect to quality of the first observation report is received (2:5) from the first data user. Rating information is then created (2:8) based on the received rating, and a second observation report originating from the same sensor and comprising said rating information is provided (2:10) to a second data user. The comprised rating information thus indicates reliability of the second observation report. Thereby, the second data user is enabled to estimate and use the second observation report depending on its reliability as indicated by the rating information.
摘要:
A method and a server (300) for handling database queries directed to a semantic database (302) with stored information according to a preset ontology structure and annotated as element identifiers comprising triplets with a subject, a predicate and an object. In the server (300), a data analyser (300a) collects statistics from the database and defines semantic rules from the information in the database. When a database query is received with a first set of sub-queries, a query optimiser (300c) rewrites the query as a second set of sub-queries in the triplet format based on any of the ontology structure, the collected statistics and the defined rules. A Reduction Rate RR is also calculated for the sub-queries relating to the number of distinct subjects and objects appearing in the database with the predicates of the sub-queries. The sub-queries of the second set are finally provided as a modified query in an order according to decreasing Reduction Rates for execution in that order when searching the database.
摘要:
A method in a Service agent, a Service Agent and a computer-readable medium comprising a computer program are provided for providing a service to a user. The method comprises detecting connection of a Personal Profile Device, operated by the user, to the Service Agent. The method further comprises receiving a service information message from a Service Provider, comprising a service identifier, and obtaining a service profile from the Personal Profile Device using the service identifier. The method further comprises logging in to at least one Information Source identified from the service profile using personal credentials comprised in the service profile in order to allow the Service Provider to access the information needed for providing the service and requesting the Service Provider to set up a connection to the at least one Information Source and to obtain the information needed for providing the service. Thereby, delivery of the service from the Service Provider to a Service Endpoint, which is operatively connected to the Service Agent, based on the information is enabled
