Title: Wireless information device running multiple interactive applications
Inventor: TASKER MARTIN PAUL
IPC: H04L29/06
Filed: 2001-02-14
Abstract: A wireless information device (eg a mobile phone) is programmed with client software including a first application (Battleships) which communicates using datagrams with a second application in accordance with a bearer/Channel protocol interface (Infrared/SMS), in which the device comprises a software server (GSDP, GDP) to mediate the communication between the first application and the second application and to control the selection of the appropriate bearer protocol interface from several such bearer protocol interfaces. The bearer is treated as connectionless and unreliable/best effort, and a server interface to the client software is session-based but unreliable, and is independent of the bearer. A further protocol layer RGCP may be included to provide reliable communication.

Patent GB-2375028-A (GB)
Title: Processing speech signals
Inventor: EALEY DOUGLAS RALPH
IPC: G10L25/90
Filed: 2001-04-24
Abstract: A method of processing a speech signals comprises: determining a frequency spectrum of a speech frame; determining a pitch value for the signal; identifying peaks (12,14,16 - Fig 3); (22,28,32 - fig 6a) in the spectrum and evaluating the peaks to determine individual scores for the peaks; the scores being a measure of the likelihood that a peak is a harmonic of the speech signal. Peaks may be evaluated by analysing the frequency position of a peak relative to one or more other peak. This removes the need for high accuracy in determining the fundamental frequency as there is no need to predict long sequences of harmonic positions. Another embodiment, comprises the steps of: normalising a speech energy level of a signal and deriving a root cepstrum using the normalised speech energy level. A further embodiment comprises: identifying peaks in a spectrum by differentiating the spectrum using two scales, and weighting the results from the two scales so that the differentiation using the second scale improves the accuracy of the first.

Title: Removal of grain
Inventor: PETTIGREW DANIEL
IPC: H04N5/21
Filed: 2003-04-05
Abstract: The invention disclosed is for grain removal in image processing. An operator selects a sample of screen elements of a displayed image.

This volume is then transformed to a different co-ordinate system wherein the distance between pixels at the extremities of the longest orthogonal axis represents grain to be removed from the image. By processing the pixels according to the distance between colour co-ordinate values and averaging colour co-ordinates, the grain can be removed from the image.
