Abstract: In a general aspect, detected motion is localized based on channel response characteristics. In some aspects, channel responses based on wireless signals transmitted through a space between wireless communication devices are obtained. A motion detection process is executed to detect motion of an object in the space based on the channel responses, and the channel responses are analyzed to identify a location of the detected motion within one of a plurality of regions within the space.

Abstract: A method for representing state transitions within a state machine includes representing a set of allowed transitions between states as a transition pair wherein a first value of the transition pair indicates a set of nodes from which to transition and a second value of the pair indicates a set of nodes to which to transition. The nodes represent states within a state machine. The method further includes defining a role of an entity within the state machine by assigning a number of transition pairs to the entity, the value pairs defining how the entity can transition through the state machine.

Abstract: A computer implemented method, apparatus, and computer usable program code for managing a dynamic cluster. Processor usage is monitored in the dynamic cluster, wherein applications execute on partitions in the dynamic cluster. In response to a determination that the processor usage exceeds a threshold level, applications are rebalanced within the dynamic cluster in a manner that reduces processor usage.

Abstract: A collaborative Web research method (and system), includes organizing a plurality of documents in a N-dimensional space according to a collection of subject words, and based on the organizing, retrieving, by a user, said documents organized in the N-dimensional space according to the collection of subject words.

Abstract: A Graphical User Interface (GUI) (and method for navigating data blocks) includes a display window, and a retrieval object displayed on the display window for assisting a user in retrieving data which is spatially organized in N-dimensions and displaying the data on the window.

Abstract: A method (and system) of predictive directional Web caching, includes detecting a first document accessed by a user, and predicting a subsequent document which, with a highest degree of probability, is likely to be retrieved based on the first document accessed.
