Title: Two-level BCH codes for solid state storage devices
Inventor: CIDECIYAN ROY D
IPC: G06F11/10
Filed: 2011-03-23
Abstract: Methods and apparatus are provided for encoding input data for recording in s-level storage(2)of a solid state storage device(1), where sâ ¥2. Input data words are encoded in groups of M input data words in accordance with first and second BCH codes to produce, for each group, a set of M first codewords of the first BCH code. The set of M first codewords is produced such that at least one predetermined linear combination of the M first codewords produces a second codeword of the second BCH code, this second BCH code being a sub- code of the first BCH code. The sets of M first codewords are then recorded in the s-level storage(2).If each of the first and second codewords comprises N q-ary symbols where q =pk, k is a positive integer and p is a prime number, the q-ary code alphabet can be matched to the s-ary storage (2) by ensuring that q and s are uth and vth powers respectively of a common base r, where u and v are positive integers and kâ ¥u, whereby p(k/u)v = s.

Title: Data encoding and decoding
Inventor: GAMEI JAMES ALEXANDER
IPC: H04N19/126
Filed: 2013-09-25
Abstract: An array , e.g. blocks, of video data values is encoded in which a determination is made (1300) as to whether a transform skip mode is applicable to the array. If a transform-skip mode is not applicable to the array, the data is frequency transformed and the resulting array of frequency transformed values is quantised by applying quantisation parameters which may vary between values in the frequency transformed array according to the position of each frequency transformed value within the array, e.g. a scaling list of a variety of values (1320). If a transform-skip mode is applicable to the array, the data values are quantised by applying quantisation parameters which are independent of the position of each value within the array, which may constitute a single value for all (1310). Corresponding decoding is also disclosed. An undesirable fish scale effect (fig. 20) is thereby avoided.

Title: Particle beam irradiation system and method for operating the same
Inventor: NISHIUCHI HIDEAKI
IPC: H05H13/04
Filed: 2014-01-27
Abstract: Operation control data of each of the constituent sub-units of a synchrotron particle beam irradiation system 1 is constructed by a combination of module data items (initial acceleration data item, plural energy change data items, and a deceleration control data item), corresponding to plural control intervals. A control start value, a control completion value, and a computing function for connecting the control start value with the control completion value are expressed in each of module data items. Further, the plural module data items are corrected on the basis of a correction data item of a residual field, and a power-supply control command value is sequentially outputted. Correction table data of the residual field, expressed by irradiation energy and irradiation stage numbers of the irradiation energy, is pre-prepared. Altering the control data by accessing the correction data tables is intended to provide a quick transition from one energy level to another and ensure that the energy levels are reproducible.

Title: Method for detecting conflicts between aircraft
Inventor: BARKER KENNETH FREDERICK MILES
IPC: G08G5/00
Filed: 2015-07-22
Abstract: For pairs of aircraft whose 2-D or 3-D flight routes 402, 404 violate a proximity test, the parts of their flight routes that breach a horizontal separation threshold 308 are identified as conflict paths 406, 408. Aircraft conflicts are then identified for portions of the trajectories corresponding to the conflict paths (Figs.6-7). Thus portions of the trajectories corresponding to positions outside the conflict paths may be eliminated from the conflict detection, increasing computational efficiency. Time separation and altitude separation of pairs of aircraft that have not flown past their conflict paths may be used to predict loss of separation. Graphical warning indications for pairs of hazarding aircraft may show time separation (1616, Fig.16) and rate of change thereof. Conflict paths may be pre-determined, stored and used later for conflict detection in an air traffic control system.
