Abstract: Various methods and apparatuses are provided for performing a radix-M FFT (Fast Fourier Transform) upon N time domain samples to produce N/S frequency domain samples for detecting tones of dithers impressed on channels of a WDM (wavelength Division Multiplexed) optical signal. Successive tones have a tone frequency spacing, .DELTA.f ta, and a sampling frequency, f S, is chosen so that f s = N.DELTA.f ta/S. S is a spacing given by S = M w with w being an integer. The radix-M FFT is performed in k = log M(N) stages and within the stages a reduced number of radix-M computations, when compared to the number of radix-M computations of a conventional radix-M FFT, are performed on data points associated with the N time domain samples. This is possible because successive frequency domain samples of the N/S frequency domain samples differ by .DELTA.f ta = S.DELTA.f where .DELTA.f is a frequency bandwidth.

Abstract: L'invention concerne un procédé d'augmentation de la concentration d'un mélange liquide par distillation osmotique, de manière qu'un composant volatil soit transféré du mélange en contact avec un côté d'une membrane perméable aux gaz (32), non poreuse, et de préférence à volume libre élevé, à une solution de séparation en contact avec l'autre côté de la membrane. Du fait de sa nature non poreuse, la membrane perméable aux gaz résiste à la pénétration de composants huileux susceptibles d'être présents dans le mélange d'apport, et au mouillage par ceux-ci. De même, l'occlusion de la membrane par des solides est empêchée. De préférence, un copolymère amorphe de perfluoro-2,2-diméthyl-1,3-dioxole est utile pour la membrane perméable aux gaz. La distillation osmotique dans laquelle est utilisée ladite membrane perméable aux gaz, à volume libre élevée, permet la concentration de mélanges liquides difficiles à traiter, tels que des jus de fruits pulpeux, et notamment, les jus contenant du limonène comme, par exemple, le jus d'orange. Ledit procédé peut être mis en oeuvre dans des conditions de flux élevée, sur des longues périodes entre les nettoyages de la membrane. De plus, une faible contamination par la solution de séparation dans un réservoir (22) du mélange d'apport du réservoir (40) est obtenue, ce qui permet la production d'un concentrée de grande qualité.

Abstract: A system for rate control during transcoding and encoding of digital video data in a multi-program transmission environment accommodates changes in the GOP structure of any of the programs, e.g., due to a commercial insertion or the like. A  hierarchical bit allocation scheme is used, where bits are allocated on a super group of pictures (GOP) level (106), i.e., a grouping of multiple GOPs, a super frame level (104), and an individual frame level (102).  The bit allocation for the super GOP and each picture is adjusted when a change in the structure of a group of pictures (GOP) is detected for any of the pre-compressed programs. The super GOP length may also be adjusted if required to maintain an integer number of GOPs therein. A change in the GOP structure is detected based on a change in the GOP length or sub_GOP length (distance between P pictures). For pre-compressed data, initial GOP lengths and su_bGOP lengths can be assumed and adjusted as required based on actual measurements. For a current I or P  picture, the sub_GOP length is calculated based on temporal references of the current picture and a previous I or P picture. For a current B picture, the same calculation is used, plus one picture.

Abstract: The invention concerns a method for making a quasi-incompressible phase-change material (PCM) having low thermal conductivity, the resulting products and their uses. The method consists in combining with a phase-change material (PCM) in liquid state a thickening agent selected to reduce significantly thermal convection, the formed material having, depending on the combinations performed, a gelled structure or a colloidal dispersed system. The PCM consists of a mixture of chemical compounds of the family of alkanes, paraffins, waxes, fatty alcohols, fatty acids and the like, and the thickening agent can be organic (aromatic ureas), organometallic (alkaline or alkaline-earth soaps) or purely inorganic (silica, silico-aluminates such as bentonite made oleophilic). The invention is useful for thermal isolation of containers or ducts, and in particular for thermal insulation of hydrocarbon ducts.

Abstract: when an orthodontic appliance is attached to the lingual side (back side) of teeth which is invisible from the outside, a large difference in level of the surface between adjacent teeth requires utilization of a wire bent in a complicated fashion. It has been found, however, that the difference in level between adjacent teeth is very small in a horizontal plane at a boundary between a crown and a root, thereby making it possible to draw a smooth envelope therealong. Based on this finding, with a view to placing a wire along such an envelope, a "lingual straight archwire" having a planar configuration comprising a simple curve and straight lines smoothly connected to ends of the curve and residing in a single horizontal plane and a bracket having a configuration suitable for the placement of the archwire are provided.

Abstract: Methods and reagents for obtaining simplified mixtures of peptides from a sample containing a number of peptides are disclosed. The simplified sample can be easier to analyze than the original peptide sample yet it is representative of all or nearly all of the proteins present in the mixed protein sample from which the original and more complex peptide sample was derived. The methods entail the use of tagging moieties that include an amino-acid-specific reactive group (R). The tagging moieties "tag" peptides or proteins at specific amino acids (e.g., by reacting with an amino acid to form a covalent bond), ultimately allowing the isolation of peptides that contain those specific amino acids. Other methods entail the used of a reactive moiety (Rp) that comprises a reagent that selectively interacts with selected proteins, either covalently or noncovalently. For example, Rp can be a natural ligand for a receptor that is to be taged or a protein that interacts with a second protein that is to be tagged. It can be an enzymatic substrate or other element of molecular recognition such as an antibody, ATP, GTP, NAD, NADP, NADH, NADPH, ubiquitin, or structural analogs thereof.

Title: Call centres

IPC: H04M3/51
Filed: 2002-04-17
Granted: 2008-02-12
Abstract: A multimedia call centre is formed by providing agent group handlers and generic queue handlers, which communicate over a LAN. The generic features of the queue handlers are an input, and a ranked set of outputs, each having a store for a designer-defined destination address. In this way, media input queue handlers can be commanded to route directly to an agent group handler, via a primary output, or to a following queue handler in dependence upon a selection parameter of a call record, e.g. a user dialled digit in response to a menu announcement from an IVR apparatus, and in this case the menu digits will have a corresponding ranking so that the ranked outputs can be used directly for routing to the appropriate next handler. The designer can specify destinations for secondary and other outputs, which could be overflow agent group handlers, further queue handlers, or, in the case of a second stage queue handler, the network input of the first stage queue handler.
