Abstract: Described herein is an energy harvesting system comprising a transducer and a processor. The transducer generates an electric signal from ambient energy. The processor is configured to process the electric signal to perform pattern recognition of the electric signal so as to determine and output a characteristic of a source of the ambient energy. The pattern recognition comprises statistical analysis and frequency domain analysis.

Abstract: Described is device for monitoring an activity. The device comprises a transducer that generates electric power from the activity and an energy store that stores the electric power over consecutive time intervals. The device further comprises a transmitter that periodically transmits the stored energy as an activity pulse indicative of an activity classification.

Abstract: The present invention generally relates to a support structure for Tidal Energy Converters (TECs), the support structure being for completely submerged deployment. A preferred support structure includes a single stanchion 4, extending in a first direction, and a cross arm 5, extending in a second direction perpendicular or substantially perpendicular to the first direction. The cross arm 5 is statically attached to the stanchion 4, and can support a plurality of TECs 3. A support structure also includes a support frame 7, which extends further in a third direction, perpendicular or substantially perpendicular to the first and second directions, than in the second direction. The support frame 7 is operable to anchor the support structure to a seabed.

Abstract: The invention concerns presence of users, such as online presence in a broadcast domain. First one-way encrypted (e.g. hashed) presence information of multiple users is received (42) from their respective devices. Then for each received presence information, attempting to match (44) that received hashed presence information to a token of a stored set of tokens where each token corresponds to a user. The presence of a subset of the multiple users for which a matching token is in the stored set is determined, causing the generation (46) of an indication of the presence of one or more users of the subset of the multiple users. Aspects of the invention include methods, systems and software.

Abstract: The invention enables identifying relationships between users of a online communications domain such as a social networking website. First identification tokens 20, 34 and 36 are stored that are each encrypted identification information associated with a domain user A, B and C. Then the service provider 58 receives relationship tokens 72 from a first user A, wherein each relationship token 72 is one-way encrypted identification information associated with a possible domain user B and C. The service provider 58 compares the relationship tokens 72 to the identification tokens to identify any matches. For each match to a unique domain user B and C, identifying a relationship between the first user and the domain user B and C associated with the matched identification token. This relationship allows communication in the domain between the first user A and the domain user B and C. It is an advantage of the invention that the relationships between users can be identified while preserving their privacy.

Abstract: Server-to-user delivery of a data stream associated with a service provided by the server is effectuated by selecting the server and, automatically and without manual intervention, providing in a communication path that is to be used for the delivery a proxy that performs a proxy operation on the data stream during the delivery. A proxy can be automatically installed in a communication path through a data network. In response to an installation request, a communication port for coupling to the communication path is automatically allocated and a proxy to support data flow through the communication port is automatically loaded. The proxy is operable for performing a proxy operation on the data stream. In maintaining proxies in a communication path used to deliver from a server to a user a data stream associated with a service provided by the server, it can be determined when a first proxy in the communication path is not performing its proxy function within the communication path.

Abstract: An inside-realm node (A) attempting to connect to an outside-realm node (B) through an intermediate gateway (30) requests central configuration from a gateway resource manager (40). In response to the configuration request initiated from the inside-realm node, an outside-realm gateway address and an inside node port number are centrally allocated to the inside-realm node by resource allocation logic (42). Establishment of the connection is initiated at least partly based on the allocated address and port number by means of appropriate signaling with the gateway (30). The allocated address and port number are signaled back to the requesting inside-realm node in a configuration reply, allowing inside-realm node to configure its communication interface accordingly.

Abstract: In requesting a server to provide a service to a user, a user application provides a service request that includes first information which directs the server to route to the user application a data stream associated with the service. The first information is transformed into second information which directs the server to route the data stream to a proxy which is installed in a communication path from the server to the user application and which is operable for performing a proxy operation on the data stream.
