Title: Fast metric calculation for viterbi decoder implementation
Inventor: PIELMEIER STEFAN
IPC: G06F11/10
Filed: 1999-07-15
Granted: 2007-04-03
Abstract: A method and apparatus are used for determining a metric in a decoding algorithm, such as a Viterbi algorithm, using an n-bit processing module, on the basis of plural m-bit soft input words, wherein n.ge.2xm. The technique comprises:  receiving plural m-bit soft input words; assembling at least two of the plural m-bit soft input words into a single n-bit composite soft input word; computing the respective distances between the at least two soft input words in the composite soft input word and expected codeword values to produce a composite distance word: summing the respective distances together to produce the metric: and extracting the metric. The n-bit processing module may comprise a 16-bit processing module employing 16-bit words, and the m-bit soft input words may each comprise a 4-bit word. Processing the plural soft input words en bloc increases the speed and information transfer rate of the decoder, and reduces the memory requirements of the decoder.

Title: Method for making a supported catalyst
Inventor: DODELET JEAN-POL
IPC: B01J37/02
Filed: 1999-12-03
Granted: 2004-04-06
Abstract: The invention concerns a method for making a supported catalyst with a nanocrystalline structure and large specific surface area wherein the first step consists in preparing a nanocrystalline material consisting of a metastable composite or alloy of at least two distinct chemical compounds or elements containing at least a catalytic species. The resulting material has a nanocrystalline structure with crystals having a size less than 100 mn. The second step consists in subjecting the nanocrystalline material to leaching using a so-called leaching solution so as to eliminate partly or completely at least one of the compounds or elements of the material, other than the catalytic species. Advantageously, a non-leachable chemical compound or element acting as support to the catalytic species, such as carbon black, is added to the material in the first step or to the leaching solution in the second step. The use of a non-leachable chemical compound or element enables to further separate the particles and the nanocrystals and consequently to increase the catalyst active surface. Thus it is possible to decrease the amount of the species having a catalytic function which often is costly. Said method enables to obtain a catalyst support in the form of a nanocomposite, a solid solution, an intermetallic compound or a combination thereof as the case may be, with a nanocrystalline structure and a large specific surface area usually more than 2 m<2>/g.

Granted: 2007-12-04
Abstract: The invention provides an IgE and antigen-specific screening assay for use in identifying agents which suppress the IgE mediated immune response to antigen. The assay is performed in vivo in Animals which hyper respond to antigen by producing exaggerated levels of IgE. The animals are sensitized to an antigen during a specific window of sensitivity which closes a day after the animal has been treated to produce the IgE hyper responsive phenotype. The screening assay is performed in the animals by treating them with a candidate IgE suppressor agent in conjunction with further immunization made after closure of the window of sensitivity defined by the invention. Positive results (indicating that the candidate agent has IgE suppressive activity) are obtained in the assay through measurement of a decline in antigen-specific IgE in the animal following its treatment with the candidate agent. The screening assay may also be utilized to measure other components of the immune response to antigen, including IgG1 and IgG2a antibody production.

Abstract: An agricultural combine having a supporting structure that is driven by ground engaging wheels at a harvesting speed by a propulsion assembly. The combine is also provided with a threshing assembly that is driven by a variable torque sensing drive. The variable torque sensing drive is manipulated by pressurized hydraulic fluid. A  hydraulic sensor in hydraulic communication with the variable torque sensing drive provides an actual hydraulic pressure signal that is directed to an electronic controller. An operator control in the operator's cab of the combine provides a loss rate signal that is also directed to the electronic controller. The electronic controller converts the loss rate signal into a desired hydraulic pressure signal. The electronic controller regulates the forward speed (harvesting speed) of the combine so that the desired hydraulic pressure signal is equal to the actual pressure signal. The harvesting speed regulation can be modified or overridden by moisture signals from a moisture sensor located in the feederhouse for sensing the moisture content of harvested crop.

Abstract: The present invention relates to a method and system for activating a context in a first network so as to transfer a call and/or a transaction via said first network and a second network. Initially, an application protocol such as H.323, H.248 or SIP is set up using a signaling or default context within the first network. Based on a message of the application protocol transmitted from the second network, a capability information is determined and used to activate the context. Thereby, the capabilities can be agreed in advance and the context can be activated e.g. as a secondary context for both mobile-originated and mobile-terminated calls and/or transactions. Accordingly, a reservation protocol is no longer required to signal the capability requirements to the second network, and signaling load can be decreased.

Abstract: An optical image characterizer (10) detects light energy as discrete angular orientations of a slit in a rotating spatial filter positioned at the focal plane of a Fourier transform lens, where a Fourier transform pattern of spatial frequencies of an image are formed. Detection of light energy with a small array (e.g., 16 x 16) photodetector is enhanced by splitting the beam containing the filtered light energy pattern and projecting it onto two photodetector arrays in offset, virtual juxtaposed relation to each other.  Detected light intensities I at discrete angular orientations R are stored in RIXel data arrays with or without searchable flags X, such as distortion factors.
