Granted: 2005-02-08
Abstract: Selon la présente invention, un terminal de réseau mesure la qualité de la réception et transmet les résultats de la mesure à une station de base. La station de base commute la vitesse de transmission sur la base des résultats qui lui ont été transmis. Lorsque la qualité de réception du terminal de réseau diminue, la vitesse de transmission est commutée. La vitesse de transmission est également commutée dans le but de faire tomber les interférences avec une autre transmission dans une plage acceptable en fonction de l'état du canal reliant le terminal de réseau et la station de base.

Title: A method of estimating the location of a cable break including a means to measure resistive fault levels for cable sections
Inventor: VOKEY DAVID E
IPC: B60N2/90
Filed: 2000-02-14
Granted: 2003-04-22
Abstract: A method and apparatus are used for locating cable breaks and resistive faults in cables, including fibre optic cables. The conductive shield or armour of the cable is divided into sections, usually at a splice. A step function voltage is applied to one end of the conductive shield. Remote sensors at the end of each section monitor the voltage and current as a function of time and at steady state. The measured data are encoded as current pulses and transmitted along the armour to the end of the cable. A computer at the cable end calculates from the measured voltages and currents the capacitance of each section of the shield. A broken section is identified by comparing the calculated and original capacitances of the sections and the distance along the broken section to the break is calculated from the calculated and original capacitances of the broken section. Resistive faults in the cable are located by calculating a fault resistance of each section of the shield from the measured steady state voltages and currents. A section containing a resistive fault is identified from the magnitude of the calculated fault resistance and the distance to the resistive fault is calculated from the measured steady state voltages and currents of the faulted section.

Title: Improved methods of identifying peptides and proteins by mass spectrometry
Inventor: SKILLING JOHN
IPC: G06F19/00
Filed: 2000-04-06
Granted: 2004-01-06
Abstract: A method of identifying a protein, polypeptide or peptide by means of mass spectrometry and especially by tandem mass spectrometry is disclosed. The method preferably models the fragmentation of a peptide or protein in a tandem mass spectrometer to facilitate comparison with an experimentally determined spectrum. A fragmentation model is used which takes account of all possible fragmentation pathways which a particular sequence of amino acids may undergo. A peptide or protein may be identified by comparing an experimentally determined mass spectrum with spectra predicted using such a fragmentation model from a library of known peptides or proteins. Alternatively, a de novo method of determining the amino acid sequence of an unknown peptide using such a fragmentation model may be used.

Abstract: A multi-wavelength optical cross-connect switch architecture incorporates a plurality of wavelength-selective optical cross-connect (WSXC) switch fabrics that receive multi-wavelength input signals distributed by one or more optical slicers and generate multi wavelength output signals that are combined by a plurality of optical combiners. The WSXC fabrics employ fiber Bragg gratings (FBGs) as wavelength-selective elements. Using this architecture, the number of multi-wavelength channels carried by each WSXC is reduced from the number of channels present in each multi-wavelength input signal. In addition, the wavelength spacing between adjacent channels carried by each WSXC is increased over the spacing between adjacent channels in each multi-wavelength input signal.

Title: Golf club head with dynamically movable centre of mass
Inventor: ELLEMOR JOHN WARWICK
IPC: A63B53/14
Filed: 2000-08-18
Granted: 2008-10-14
Abstract: A golf club, namely a driver, includes a flowing moving part within the head such as mercury or a flowable solid in an inclined U shaped hollow passage (11). The moving part (12) remains captive at the rear of the head during the downswing on an axis defined by the direction of travel and the centre of mass. A golf ball impacting the head away from this axis e.g. at the toe (17) causes the head to rotate and subsequently causing the flowing moving part (18) and hence the centre of mass to move to behind the point of impact i.e. the toe, thus reducing head rotation and increasing the sweet spot.
