Patent GB-201109697-D0 (GB)
Title: Rotating blade analysis
Filed: 2011-06-10
Abstract: A method of analysing blade displacements is provided. The blade displacements are detected by a plurality of circumferentially spaced stationary timing probes associated with an assembly of rotating blades mounted on a rotor. The blade displacements correspond to the times at which the blades pass the respective probes. The method including the steps of: 
(a) identifying a possible resonant vibration event in the assembly of rotating blades; (b) zeroing the blade displacements on the rotations identified with the resonant vibration event to remove invariant blade displacements; (c) fitting modelled blade displacements corresponding to possible blade vibrational deflections at a plurality of frequencies to the zeroed blade displacements; and (d) characterising the resonant vibration event by identifying at each rotation the frequency having modelled blade displacements which correlate best with the zeroed blade displacements. Step (c) includes performing at each individual rotation identified with the resonant vibration event the sub-step of: (c-i) fitting the modelled blade displacements at each frequency to the zeroed blade displacements for a plurality of successive rotations which include that individual rotation.

Title: Processing system, method and computer program for multipoint communications
Filed: 2011-11-04
Abstract: A network sends to a user equipment UE a reference signal configuration, and from receiving it the UE selects a codeword identifying a cooperative multipoint CoMP transmission scheme. There is a CoMP scheme selection codebook from which the UE selects the codeword corresponding to its recommended CoMP scheme. The UE sends to the network that codeword which identifies the CoMP transmission scheme, along with the CSI feedback characterizing the CoMP transmission scheme. From that codeword which the network receives it determines the UE's assumed CoMP transmission scheme, which the network uses to determine how the CSI feedback, received from the UE, was calculated by the UE (for example, joint transmission, or dynamic point selection with or without muting, or coordinating scheduling/beamforming). The network uses this information for selecting a CoMP transmission scheme for downlink CoMP transmissions to the UE.

Title: High-momentum particle accelerator
Filed: 2011-12-09
Abstract: The kinetic energy of particles from the large microscopic to the small macroscopic range can be increased with existing technology by using intense electromagnetic (EM) radiation. Several possible candidate physical processes exist using a single basic apparatus setup. Upon interaction, radiated EM energy is converted to total particle kinetic energy (internal, rotational and translational). Particles with an unprecedented combination of high rest mass and high-laboratory frame kinetic energies may be projected. In the energy transfer processes, thorough particle disintegration by EM radiation may be avoided if the duration of irradiation is briefer than the temporal measurement indeterminacy imposed by Heisenberg's uncertainty principle. Impact of the particle on a suitable target will result in "contact and compression" (amongst other heating effects). If the particle surface exceeds the speed derived from the critical temperature, Lawson's criteria will be satisfied and thermonuclear fusion is anticipated.

Title: Method and apparatus for simulation of lithography overlay
Filed: 2012-07-09
Abstract: A method for simulation of lithography overlay which comprises storing alignment parameters used to align a semiconductor wafer prior to a lithography step; storing process control parameters used during the lithography step on the semiconductor wafer; storing overlay parameters measured after the lithography step; calculating alternative alignment parameters and alternative process control parameters. The alternative alignment parameters and the alternative process control parameters are added to cleansed overlay parameters to obtain simulated lithography overlay data. The simulations allow the testing of assumptions regarding the number of measurements which need to be carried out as well as potentially providing a control method for optimisation of throughput of the lithography process. Figure 1 shows a fabrication unit 1 for patterning a surface of a semiconductor wafer 10, comprising an exposure tool 20, and exposure controller 30, a developing unit 40 and an overlay measurement tool 50. The simulation processor 60 includes non-volatile memory for storage data. Figure 2 show the wafer exposure field (70, figure 2) with lower overlay marks (71, figure 2). These lower layer overlay marks (74 figure 3a/b) and upper layer overlay reference marks 74 are used to obtain overlay error measurements (see figure 3a/b).
