Title: A method and system for performing a fast-fourier transform
Inventor: DAVEY STEPHEN W
IPC: G06F17/14
Filed: 2002-08-15
Abstract: In a method for performing a fast-fourier transform (FFT), input data samples are written to a storage instance in a data input step, then subjected to a processing step in which the stored input samples are read out of the storage instance and processed in accordance with a transformation algorithm. The resulting output data samples are written back to the storage instance and, in a transformed data output step, read out of the storage instance, successively received batches of the input data samples being fed cyclically to a plurality of such multiple-function storage instances. Each batch is fed to a respective storage instance such that, at any given time during performance of the method, the input, processing and output steps are being performed simultaneously in respect of different batches using different respective storage instances. For each received data input batch, the processing step comprises a plurality of calculation passes creating intermediate data values which are stored between passes in both the respective multiple function storage instance and a further storage instance which is substantially dedicated for use in such processing steps. The invention also includes a related method for performing an inverse fast-fourier transform (IFFT), as well as FFT and IFFT systems.

Title: Establishing a chain of secure communication links for delegation
Inventor: KALOGRIDIS GEORGIOS
IPC: G06F21/60
Filed: 2002-08-30
Abstract: The invention relates to secure communication links for establishing chains of accountability in systems where trust is delegated. A first data processing system initialises a secure communications link with a second data processing system by i) generating a message comprising a delegation token and authentication data, the token including a delegation key and associated request data, and the authentication data being generated by operating on the token with a secret key, and ii) encrypting the message with a key known to the second system and iii) sending the encrypted message to the second system. The second system decrypts the message, verifies the authentication data, and uses the delegation key to establish secure communications with the first system. A cascaded chain of secure links can be established by repeated application of this technique whereby each successive system adds a further token and authentication data to the received decrypted message to form an extended message and encrypts the extended message for onward transmission to the next system in the chain. Application is to delegated requests in a Personal Area Network (PAN).

Title: Valve assembly
Inventor: BOWE MICHAEL JOSEPH
IPC: F16K47/08
Filed: 2003-05-22
Abstract: A valve assembly (10) comprises a valve stem (14) with a bore (15) and radial apertures (17), and a sleeve (18) closed at one end and slidable over the valve stem (14) to obstruct the apertures (17). At the end of the valve stem opposite the outlet end, the valve stem (14) defines a fluidic vortex chamber (22) with both tangential inlets (28) and non-tangential peripheral inlets (26), and with an axial outlet (24) communicating with the bore (15). The sleeve (18) defines at least one radial port (32) near its closed end. The valve assembly operates in a conventional fashion except when approaching closure. Once the last of the apertures (17) in the valve stem has been closed, the only flow path is through the fluidic vortex chamber (22). Further movement of the sleeve (18) alters the distribution of the flow between the non-tangential inlets (26) and the tangential inlets (28), so adjusting the strength of the fluidic vortex and the resistance to fluid flow. The valve assembly (10) suppresses erosive and cavitational wear of the valve mechanism, and can provide a wide range of flow modulation.

Title: Determining if a memory error is hard error or a soft error
Inventor: THAYER LARRY JAY
IPC: G06F11/10
Filed: 2006-09-25
Abstract: The invention provides a method for determining if soft (temporary) or hard errors have occurred in memory. When an error is detected, preferably using an error-correcting code (ECC) algorithm, it is corrected and written back to the memory location where the error was detected (this is known as "reactive scrubbing"). This "corrected" data is then read back from the memory location. If the data that is read out is correct, then the memory location of the detected error is written into a register block to indicate a soft error. If the data that was read back is not correct, then the memory location must contain a hard error, and that information is written to a register block.
