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 present invention relates to a UDDI server and method in a UDDI server for mediating Web services provided by a number of service providers to a number of service requesters. The UDDI server according to the present invention is adapted to provide support for taking dynamic quality of service into account in the mediation of Web services. The UDDI server comprises a Web service register which includes data sets for storing QoS status information. The QoS status information is information on the current QoS that an associated Web service can offer to a service requester. The QoS status information stored in the data sets is updated periodically based on dynamic service status information received from the service providers. The UDDI server may optionally include a decision making function for selecting a Web service that satisfy a set of QoS requirements of a service requester.

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 analysing 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.

Methods and systems are disclosed for anonymizing a dataset that correlates a set of entities with respective attributes. The method comprises determine clusters of similar entities. Determining the clusters comprises (1) partitioning the entities into a first group with similar attributes to one another and a complement group of entities with similar attributes to one another and (2) recursively repeating the partitioning on the groups until every group meets one or more criteria. The partitioning a group comprises choosing a reference entity from the group, determining a symmetric set of attributes based on the reference entity attributes and on an average of the group's attributes, and assigning each entity to the first or second group depending on whether its attributes are more similar to those of the reference user or to those of the symmetric set.

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.

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.

The invention provides an improved recommender system that includes a client device or service provider server, a trusted function handler module and a recommender module. The recommender system functions to protect the privacy of user rating information maintained by the node (i.e., client device/server) by having the node transform the user rating information using a specific function selected by the function handler and then provide the transformed user rating information to the recommender module. In this way, privacy of the user rating information is maintained because the original user rating information will be unknown to a recommender module.
摘要:
A method and arrangement for creation of a customized recommendation of items in a user device (200) in communication with a recommendation system (202). The recommendation system obtains (2:2a) ratings of items for a public recommendation based on public user data (202a) and obtains (2:2b) attribute-related weight information for said items with item-specific weight values for a plurality of attributes pertaining to user characteristics. The ratings of items in the public recommendation and the weight information are sent (2:3) to the user device which then modifies (2:4, 2:4a) the public recommendation into a customized recommendation by selecting attributes valid for a current user based on said private user data, and applying the weight values of the selected attributes only to the received ratings of items. The non-valid attributes are thus disregarded. Thereby, new item ratings are obtained which have been adapted to the characteristics of this particular user.

The invention relates to a method 20 performed in a profile mediator device 5 for exchanging user profile UP1 of a user between a first service provider SP1 having a first user profile UP1 for the user, and a second service provider SP2. The method 20 comprises: receiving 21 from the second service provider SP2 a request for the user profile UP1; retrieving 22 a policy corresponding to the user profile UP1; generating 23 a request identification Q12 for the request; and sending 24 the request identification Q12 to the second service provider SP2, the request identification Q12 enabling the first service provider SP1 to exchange the user profile UP1 with the second service provider SP2 in accordance with the policy. The invention also relates to a profile mediator device, agents, computer programs and computer program products.
摘要:
According to a first aspect of the present invention there is provided a method of at least partly delegating processing of data in a machine-to-machine system to reduce computational load on a broker entity 11 while maintaining security of the data to be processed, the broker entity 11 serving as a link between a node 13 of a sensor network providing the data and an application node 12 requesting the data. In the method, at the broker entity 11, following receipt of a request for processed data from the application node 12, determining the node to provide the data to be processed, generating a data key for the data-providing node 13, generating a data-processing algorithm for processing the data in dependence upon the request, sending the data key to the data-providing node 13, and sending the data key and data-processing algorithm to a remote data-processing entity 15. At the data-providing node 13, encrypting the data using the data key and sending the encrypted data to the data-processing entity 15. At the data-processing entity 15, decrypting the data using the data key, processing the data using the data-processing algorithm, and sending the processed data to the application node 12.
