According to one embodiment of the present invention, a computer-implemented method of generating a sensory representation of a qubit is disclosed. The computer-implemented method includes determining a point in a Bloch sphere based on the qubit, in which the point is defined by a value of colatitude (theta) with respect to the z-axis of the Bloch sphere, and a value of longitude (phi) with respect to the x-axis of the Bloch sphere. The computer-implemented method further includes converting the value of colatitude (theta) to a value of a first variable of a sensory output space. The computer-implemented method further includes converting the value of longitude (phi) to a value of a second variable of the sensory output space.

Qubit sensory representation

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. 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.

Determining the status of a device through use of a publisher/subscriber interface

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.

Producing special effects to complement displayed video information

A device for enabling a first computer network device to determine whether a second computer network device has an online status or an offline status includes a memory device with instructions for execution by a processor to: receive a request from the first computer network device for the status of the second computer network device; determine whether the second computer network device is online or offline; in response to a determination that the second computer network device is online, return a first network address to the first computer network device; and in response to a determination that the second computer network device is offline, return a second network address to the first computer network device, wherein the second network address is a known bad address that will not provide a response to the first computer network device.

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. The return address is used in ping messages. If the ping operation succeeds, it is concluded the publish/subscribe device is online. If the ping operation fails, it is concluded that the publish/subscribe device is off-line.

Message integrity in a messaging oriented middleware system is preserved by determining a message producer's level of message integrity by examination of connection details between the message producer and a messaging engine. The message producer's level of integrity is stored in a memory of the messaging engine. The message is then stored in the designated destination using the message producer's level of integrity. The message is sent from the designated destination to a consumer when it is determined that the consumer conforms to the integrity levels.

Preserving integrity of messages in a messaging oriented middleware system

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.

Method, apparatus and computer program for controlling retention of publications

A method of assisting a user, for use in an environment comprising: a user session, an external entity session and a forms engine for generating a form. The method comprises the steps of: registering with the user session, wherein a first session is established between the user session and the forms engine; receiving a request for assistance from a user; in response to receiving the request, de-registering with the user session, wherein the first session is un-established; registering with the external entity session, wherein a second session is established between the external entity session and the forms engine; receiving input from the external entity session; and populating the form with the received input.

Method of assisting a user

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.

Event-based activation and deactivation of subscription matching

The invention relates to a message brokering system for connecting a client in a local publish/subscribe messaging system to a remote message broker. The system comprises a message broker in said local publish/subscribe messaging system and a metabroker application means representing said remote message broker. The local message broker comprises publish/subscribe means for proxying messages between the client and the metabroker application means. The metabroker application means comprises publish/subscribe means for proxying messages between the local broker and the remote broker.

Publish/subscribe messaging

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.

Method and system for collaborative editing of a document

A broker-based publish/subscribe messaging system is administered in which a session-based network connection (such as TCP/IP) from an administrator publish/subscribe client application is established with a broker. Administration commands are received as messages from the administrator publish/subscribe client application at the broker via the session-based network connection and response messages are sent from the broker via the session-based network connection to only the administrator publish/subscribe client application.
