Abstract: A publish/subscribe interface is used to enable a non-publish/subscribe first system (such as an IP network device) to obtain status information about a publish/subscribe device that cannot be pinged by the first system. The first system sends a status request to a domain name server associated with a system known to include the publish/subscribe device. The status request includes a domain name for the publish/subscribe device. Topic space maintained by a message broker in the publish/subscribe system includes status topics associated with publish/subscribe devices. The status topics contents reflect the current availability of the associated publish/subscribe device. The domain name is mapped to a status topic associated to the publish/subscribe device identified in the status request and the contents of that status topic are retrieved. If the contents have a first value, a “good” IP address is returned to the first system. If the contents have the second value, a “bad” IP address is returned.

Abstract: A hierarchical publish/subscribe network is employed to produce and distribute special effects to users to complement displayed video information. A top level broker in the network receives a plurality of data streams corresponding to a respective plurality of primary special. A service provider makes a subscription request for one of said primary special effects and receives the corresponding selected data stream. The selected data stream is transformed into at least one further data stream, corresponding to a further special effect. The further data stream is published to a lower level broker associated with the service provider. In response to a user subscription request for the further special effect, the lower level broker publishes the further data stream to a user interface for presentation to the user in association with the displayed video information.

Abstract: Accesses to locally-relevant and contextually-relevant services information within a mobile communications environment are enabled. The solutions include an improved location determination in which a first mobile communications device processes location information broadcast by other devices via short-range wireless signals to determine its approximate location. The described solutions include a context-based selection of the most relevant of a set of locally-available services, including filtering services according to whether the first mobile device is currently moving and filtering according to a personal profile of the device user.

Abstract: The present invention provides methods, apparatus and computer programs for event-based control of subscription matching in a publish/subscribe communications environment. Activation and/or deactivation events are associated with subscriptions at a publish/subscribe broker and are used to control when a subscription is active. The broker is responsive to temporally-unpredictable events, such as receipt of a published message on a predefined activation topic, to activate subscription matching for messages that are subsequently received or which have been received earlier and retained at the broker. Conventional subscription matching can be avoided for a registered subscription while that subscription is inactive, and subscribers are not required to explicitly and repeatedly subscribe and unsubscribe.

Abstract: For managing the retention of publications in a publish/subscribe system, a publisher sends a new publication to a publish/subscribe broker with an indication of whether the new publication should be retained in association with a previous retained publication. The publish/subscribe broker responds to such indications by retaining the new publication with the previous retained publication. The contents or ‘payload’ of the new published message may be appended to a previous retained message, resulting in a single retained message that contains information from multiple published messages.

Abstract: An automated online processing super-chlorination system that monitors the chlorine levels as well as the pH levels of a main water line. Super-chlorinated water is implemented in processing water to allow poultry to be reprocessed online without removing the poultry to an offline location. The use of super-chlorinated water allows much of the pathogens of concern to be removed from the poultry while online. Chambers including jets injecting the super-chlorinated water onto the poultry as well as brushes allows actual removal of waste and fecal matter, while at the same time, sanitizing the poultry. A control section includes a chlorine and pH analyzer as well as control units to allow chlorine and pH levels to be continuously monitored and adjusted. A chlorinator and a pH adjustment system are controlled in order to inject the proper chemicals at needed and specified times.

Abstract: A method and system for collaborative editing of a document by an author of the document and reviewers. Program code receives from the author an identification of selected portions of the document and receives from the author: comments created by the author and an identification of at least one reviewer to which each comment is directed. The selected portions and the comments are associated with each other on a one-to-one basis. Each comment pertains to content of the selected portion that each comment is associated with. The program code parses the received comments, and utilizes the identification of the at least one reviewer to which each comment is directed, to generate a list of comments specifying for each comment the at least one reviewer to which each comment is directed. The program code makes available to each reviewer the comments on the list of comments directed to each reviewer.

Abstract: The invention relates to providing to a user a user interface. It is determining from a plurality interactions by a user with a first user interface whether they experienced difficulties using at least one module of the first user interface. Responsive to determining that the user did experience difficulties, that user is provided with at least one module of a different user interface. Thus it can be seen that a user is preferably provided with the first interface unless they experience difficulties with that interface. Other users who do not experience such difficulties continue to interact with the first interface.

Abstract: Provided is a data transmission method, a communications network, a mobile receiving device and data processing methods for use in broadcast of geographic information to mobile devices. The invention overcomes the problem of lack of currency of static information distribution via CD-ROM, and the problem of the cost of lengthy connections to the Internet which is a requirement of some dynamic solutions. The geographic data which is relevant to a transmitter in the network is broadcast by the transmitter as a plurality of separate data elements which each relate to and include an identification of a specific map segment of a segmented map, such that the data elements can be transmitted independently of each other and the map segment identifier can be used by the receiving device to position the geographic information of each data element within the appropriate map segment.

Abstract: The invention relates to regulating access by users to a scarce resource, wherein the resource is capable of handling multiple concurrent accesses. A request for access to the scarce resource is received and it is determined whether the access level for the scarce resource is at a desired maximum. Responsive to determining that said access level is at a desired maximum, the requester is placed in a queue for access to said scarce resource. The requester is then provided with a notification that the request has been enqueued. Access is available to the requester upon reaching the head of the queue when the access level drops below the desired maximum.

Abstract: The present invention relates to the monitoring of attempts by a reader device at reading data off a data-holding entity. Data relating to the attempt at reading the data-holding entity is received and responsive to the attempt not being successful, one is added to a read count which is used to determine the working order of the data-holding entity. The data obtained from a successful read, along transaction information is transmitted to a processing entity. This information is stored along with information relating to other data-holding entity transactions. The totality of information is periodically analysed in order to identify those data-holding entities which are repeatedly failing to be read within a predetermined number of reads/reader devices which are repeatedly failing to work properly. New data-holding entities/reader devices are sent out as appropriate.

Abstract: A known micro-payment system suffers from a problem of needing increasing network bandwidth as the granularity of the micro-payment decreases, thus increasing the latency of the processing of each micro-payment. The present system seeks to address this problem. There is disclosed a method, performed in an interactive client server system, of charging micro-payments to a third party billing server on behalf of a user using the interactive client server system, said method comprising the steps of: requesting a billing authorization from a user of the interactive client server system; receiving an authorization including an address of a billing server (e.g. from a smart card); sending an authorization message to the billing server. The billing server determines from the authorization whether the user has a valid account at the billing server. A micro-payment value may be determined from the authorization.
