A dynamic webpage processing method, including identifying a static component within a dynamic webpage, the static component comprising computer code defining at least a portion of a target webpage and configurable via first configuration data, rendering the static component as a static markup language equivalent, and returning the target webpage upon request through rendering a dynamic component within the dynamic webpage based on second configuration data is disclosed. Thus, static component(s) can be pre-rendered, leaving only the dynamic component(s) of the dynamic webpage for on-the-fly rendering when a target webpage request is made. This can greatly reduce dynamic webpage processing requirements, particularly in situations where the webpage configuration changes or evolves slowly.

A system for communicating digital data between a first and second device through audio input / output ports encodes the digital data into a series of audio frequency tones. The audio frequency tones are transferred between the devices as audio inputs. Audio decoding software residing on the devices monitors the audio inputs of the devices for audio signals representing digital data and decodes the audio signals into digital data when they are detected. The audio decoding and encoding software is preferably aftermarket software that is downloaded to the device through a digital data port and executed by the device's operating system software. The system can be used to provide a low cost accessory that can communicate digital data to a device without using the device's digital input / output port or requiring any expensive digital communication circuitry in the accessory.

A pixel image enhancement system which operates on color or monochrome source images to produce output cells the same size as the source pixels but not spatially coincident or one-to-one correspondent with them. By operating upon a set of input pixels surrounding each output cell with a set of logic operations implementing unique Boolean equations, the system generates "case numbers" characterizing inferred-edge pieces within each output cell. A rendering subsystem, responsive to the case numbers and source-pixel colors, then produces signals for driving an output device (printer or display) to display the output cells, including the inferred-edge pieces, to the best of the output device's ability and at its resolution.

These merged sub-blocks may be used to identify both inter and intra modes for the macroblock.

Soft-handoff methods involve receiving an uplink signal from a user equipment at more than one basestation. The uplink signals are processed at each basestation before being backhauled to a common point for use to derive a single signal from the user equipment. One problem with previous types of soft-handoff methods is that relatively complex processing is required at each basestation in order to demodulate and decode the signals. It is also desired to further increase uplink capacity as compared with known types of soft-handoff methods. This is achieved by backhauling signals without carrying out any decoding of the uplink signal at the basestation. The backhauled signals are combined at a common point using maximal ratio combining before being fully demodulated and decoded. As a result capacity is increased and required user equipment transmit power is reduced.

A conference server mediates the switching of video layer information from transmitting endpoints to receiving endpoints without any intermediate coding or re-coding operations. The video conference can be integrated with an audio conference using either scalable coded audio signals or non-scaleable coded audio signals.

A coded moving-picture signal is decoded by a resolution-converting motion compensation process and a resolution-converting inverse discrete cosine transform, both of which decrease the resolution of the picture, thereby reducing the amount of reference picture data that has to be stored and accessed. The reference picture data may also be stored in a compressed form. The resolution conversion and compression processes may also be used in the coding of the moving-picture signal. The resolution-converting inverse discrete cosine transform may be performed by output of intermediate results that have not been combined by addition and subtraction in a butterfly computation.

Value based tokens are generated for inclusion on a data carrier which may be applied to a cheque or similar document. The tokens are generated by a core system, which communicates with application specific wrappers. The wrappers supply token parameters to the core that are specific to the application and the core generates the tokens, and stores them for later authentication. The core then encodes the tokens onto a data carrier under the control of the wrapper and distributes the tokens under the control of the wrapper. The tokens are encoded onto the cheque when it is printed. When a cheque is presented for authentication, for example by at a bank, the signed cheque is imaged and the token retrieved from the encoded data carrier. It is passed back to the core by the wrapper for authentication of its identification number and other parameters. The image may be sealed by a further data carrier which may be printed on the cheque or added to the electronic image. The further data carrier may include a separate token or have a token which is related to the first token. Where the data carrier is applied to the electronic image it may replace the first data carrier. The data stored on the carrier references cheque information stored at a database which is compared with cheque information retrieved from the cheque.

A computer system is arranged to automatically calculate a path along nodes in a virtual world. After the co-ordinates for the virtual world environment have been initially defined (40), including nodes along which a path may travel, the system automatically increases the density of nodes in the environment up to a desired density. New nodes are added between each pair of nodes which have line of sight to each other (44 to 47), dramatically increasing the number of available links and nodes. This is repeated until a sufficient density of nodes is reached and no more nodes are being added (48 and 49).

An expert system and a method of providing automated advice are described. The system is regularly updated by advice (or diagnosis, recommendation etc.) given by practitioners in the relevant field. The combination of the underlying facts and the consequent (human) advice is used to update a ruleset that is then used to provide automated advice.An example of financial advice is given. A database contains the details for the customers of a financial institution together with advice and recommendations given previously by the institution's human advisors. This database is used to derive a ruleset which is then applied to a subsequent customer's details in an automated manner, possibly at the user's own PC via the World Wide Web. Frequent updating using data from the human advisors' work means that the database (and hence the ruleset) are kept up to date. Consistent advice can thus be provided with minimum human interaction.

Dimensions of a surface feature are determined by capturing an image of the surface feature and determining a scale associated with the image. Structured light may be projected onto the surface, such that the position of structured light in the captured image allows determination of scale. A non-planar surface may be unwrapped. The surface may alternatively be projected into a plane to correct for the scene being tilted with respect to the camera axis. A border of the surface feature may be input manually by a user. An apparatus and system for implementing the method are also disclosed.

An improved policy enforcement architecture includes several components that improve the performance of policy enforcement in a hierarchical storage environment. A File System Query instruction permits a richer set of queries to be expressed by a policy engine, thereby permitting more complex policies to be implemented with ease. The File System result is generated at the file server, and only files of interest are forwarded to the policy engine. The file system query advantageously may be applied against a pre-generated index having one more characterizing attributes to further reduce the processing required to retrieve policy data. An Index Build instruction, added to a programming interface, allows a policy engine generate the characterizing indices in advance of use. Index maintenance techniques maintain consistency between the index and the file system to ensure that the policy can be enforced using accurate file information.

Improved skipping strategies for cochlear or other multi-channel neural stimulation implants selects N out of M channels for stimulation during a given stimulation frame. A microphone transduces acoustic energy into an electrical signal. The electrical signal is processed by a family of bandpass filters, or the equivalent, to produce a number of frequency channels. In a first embodiment, a probability based channel selection strategy computes a probably for each of the M channels based on the strength of each channel. N channels are probabilistically selected for stimulation based on their individual probability. The result is a randomized “stochastic” stimulus presentation to the patient. Such randomized stimulation reduces under representation of weaker channels for steady state input conditions such as vowels. In second, third and fourth embodiments, a variable threshold is adjusted to obtain the selection of N channels per frame.
