摘要： This invention relates to methods and systems for determining whether a reference point in a location system has changed using the entropy of channel impulse responses. In one embodiment a method of determining whether the location of a first one of a plurality of reference points used in a location system has changed is provided. The reference points each have a known initial position and the method includes the steps of: estimating a channel impulse response of a wireless channel between the first reference point and a second of said plurality of reference points; determining the difference between the estimated channel impulse response and a previously-estimated channel impulse response of the wireless channel; estimating an entropy of the difference between the channel impulse responses; and determining, from said comparison, whether the location of the first reference point has changed. In another embodiment the method includes the steps of: estimating an entropy of the channel impulse response of a wireless channel between the first reference point and a second of said plurality of reference points; comparing the estimated entropy to a previously-estimated entropy for the channel impulse response of the wireless channel; determining, from said comparison, whether the location of the first reference point has changed.

摘要： An assignment system for allocating service providers to required services, comprising: a data processing unit; a data store storing a plurality of allocation processing routines each defining a respective algorithm for determining in respect of a service which of a series of potential providers of that service is/are preferred to provide the service; and an allocation mode selector configured to access a data store storing a list of required services and attributes of each required service, to select in dependence on the attributes of one of those services one of the allocation processing routines and to cause that allocation processing routine to be executed in respect of that one of the services by means of the data processing unit so determine which of a series of potential providers of the service is/are preferred to provide that service.

摘要： A computer implemented method for generating a pattern matching machine for identifying matches of a plurality of symbol patterns in a sequence of input symbols, the method comprising: providing a state machine of states and directed transitions between states corresponding to the plurality of patterns; applying an Aho-Corasick approach to identify one or more mappings between states in the event of a failure, of the state machine in a state and for an input symbol, to transition to a subsequent state based on the directed transitions of the state machine, characterised in that one of the symbol patterns includes a wildcard symbol, and a mapping for a state representing pattern symbols including the wildcard symbol is provided in a hash table referenced based on a key, the key being based on a unique identifier of the state and the input symbol to be received, by the pattern matching machine in use, to constitute the wildcard symbol.

摘要： A system controller (20, 100, 30, 40) comprises a receiver (20) for receiving data about a system (10, 11) to be controlled and for associating the received data with a time factor; a summarizer (100) for updating a set of summary bins, each of which covers a respective period of time, and each of which stores a summary of the received data having, a time factor which falls within the respective period of time covered by the summary bin; a processor (30) for, processing the summary bins, for example in order to categorize an unknown entity (5) (such as a human user) interacting with the system under control (10, 11) (via a user interface (11) forming part of the system under control) such as into an adult interested in football, etc., and a director (40) for issuing control instructions to the system to be controlled based on the results of the processor (30). The periods of time covered by respective summary bins include overlapping periods of time and periods of time having different durations and are preferably overlapping, fuzzy, multi-scale bins.

摘要： An additively manufactured apparatus having a gas filled sealed cavity containing at least two additively manufactured cathodes and an additively manufactured anode spaced from the cathodes such that a continuous electric discharge of the gas stimulated between at least one of the cathodes and the anode provides a Boolean function output at the anode corresponding to electrical input signals at two of the cathodes.

摘要： A multi-stage event detector for monitoring a system, the multi-stage event detector including: a process generator operable to generate main and sub-processes, each main and sub-process being operable to generate and initiate a detection agent each of which is operable to be triggered by detecting the occurrence of a trigger event and to report back to its generating process or sub-process upon being so triggered. Each process or sub-process is operable to respond to receipt of a report from a triggered detection agent by reporting the detection of a multi-stage event to an overall controller.

摘要： This invention relates to methods for storing and searching data. Embodiments of the invention make use of suffix trees to support binary pattern matching. Embodiments of the invention can be shown to have comparable search speeds to searches of known suffix trees, but are advantageous in that they have lower memory usage requirements which is important in large data environments.

摘要： Methods and apparatus are disclosed for enabling selection of a remote service node from a plurality of possible nodes, each capable of providing a service, and each associated with a service node control entity. The method comprises: receiving a user request in respect of a service required by a user, the request containing a first user device routing identifier relating to the location in the network of the user device, and a service indication indicative of an appropriate service provider; identifying from the service indication a service node control entity associated with the service provider; sending to the service node control entity a service node request containing a second user device routing identifier differing from the first user device routing identifier but selected at least partly in dependence thereon; receiving from the service node control entity an indication of a remote service node capable of providing the required service; and providing an indication of the remote service node to the user device.

摘要： The invention relates to a method and system that provide a high performance and extremely scalable triple store within the Resource Description Framework (or alternative data models), with optimized query execution. An embodiment of the invention provides a data storage and analysis system to support scalable monitoring and analysis of business processes along multiple configurable perspectives and levels of granularity. This embodiment analyses data from processes that have been already executed and from ongoing processes, as a continuous flow of information. This embodiment provides defining and monitoring processes based on no initial domain knowledge about the process and such that the process will be built only from the incoming flow of information. Another embodiment of the invention provides a grid infrastructure that allows storage of data across many grid nodes and distribution of the workload, avoiding the bottleneck represented by constantly querying a database.

摘要： A shared voicemail system and method of operation in which the system comprises a computer processor configured in use to store a voice message received from a third party; in which the stored voice message is accessible to each user of a plurality of users of the shared voicemail system. The computer processor also configured in use to provide a copy of the stored message to a first user of the plurality of users, receive an indication from the first user that the message is intended to be accessed by a second user of the plurality of users and to provide a notification prompting the second user to access the message. In an embodiment, the voice message received from the third party is part of a call redirected to the shared voicemail system from a phone line shared by the plurality of users.
