Abstract: An automatic method for autonomous interactions between robots, comprising an action of automatically receiving, by a transport robot, a request for transporting a service robot. The method comprises an action of automatically computing a location of the service robot. The method comprises an action of automatically moving the transport robot to the location of the service robot. The method comprises an action of automatically sending a signal from the service robot to the transport robot using a signal emitter incorporated into a mechanical element attached to the service robot. The method comprises an action of automatically coupling, using the signal, the mechanical element to a carrier element attached to the transport robot.

Abstract: A method for detecting an anomaly in operation of a data analysis device, comprising: receiving present real-time readings of multiple sensors associated with the data analysis device, and maintaining a history of past real-time readings; determining which of said multiple sensors are correlated; computing a deviation between at least some of said present and at least some of said past real-time readings of said correlated sensors; and declaring an anomaly when said deviation exceeds a predetermined threshold.

Abstract: Methods and apparatus for image matching using local features, in particular a method and apparatus for flexible interest point computation. The method involves producing multiple octaves of a digital image, wherein each octave of said multiple scale octaves comprises multiple layers; initiating a process comprising detection and description of interest points, wherein said process is programmed to progress layer-by-layer over said multiple layers of each of said multiple octaves, and to continue to a next octave of said multiple octaves upon completion of all layers of a current octave of said multiple octaves; upon the detection and the description of each interest point of said interest points during said process, recording an indication associated with said interest point in a memory, such that said memory accumulates indications during said process; and upon interruption to said process, returning a result being based at least on said indications.

Abstract: A method for voting by peers via mobile devices operating in a network on behalf of their owners, comprising iteratively sending by a plurality of peers votes for candidates to a peer and determining by the peer, according to the votes, at least one winner candidate.

Abstract: A multi-node network that comprises a plurality of nodes, at least one of the nodes comprises a local cache for storing a plurality of matching indications at least some of which associated with a potential node. A receiving node of the plurality of nodes that is configured for receiving a matching request having a requested matching indication associated with an address of an additional node of the plurality of nodes. The receiving node is configured for identifying a match between the receiving node and at least one of the associated potential nodes by matching the requested matching indication and the stored matching indications and for informing one or more of the receiving nodes and the associated nodes about the match.
