Filed: 1996-10-04
Abstract: Une structure de rouleau de bande comprend une bande présentant un adhésif sur une face, et la bande peut être tirée d'un rouleau puis coupée en segment de longueurs variables. La bande est dotée d'une bande de papier ou d'un revêtement sur une face ou sur ses deux faces, destiné à recevoir des marques écrites, et lequel devient partie intégrante d'un segment de bande. Ainsi, une fois qu'un segment de bande a été apposé par un adhésif sur un bord de marge d'une feuille, des marques écrites peuvent être écrites sur la bande de papier ou le revêtement, formant ainsi immédiatement un onglet sur une feuille. Dans un mode de réalisation préféré, une paire de rouleaux de bande (12, 14) sont montés sur un support (16) et un des rouleaux de bande porte une bande de papier (34) et l'autre rouleau de bande (14) porte une bande adhésive (40). Lorsque les deux bandes sont tirées de leurs rouleaux, la bande de papier (34) vient se fixer sur une moitié de la bande adhésive (40) de l'autre rouleau. Ensuite, on découpe les bandes en un segment et on les colle sur la feuille sur laquelle on veut placer un onglet.

IPC: H04B17/391
Filed: 1999-04-23
Abstract: A fast-converging, computationally simple, method for recognizing a single frequency tone or a sinusoid in a signal without prior knowledge of the tone frequency. The method employs a second order or higher auto-regressive model and includes: (a) sampling the signal at a constant sampling rate, and, for each sample, recursively determining a finite number of correlation coefficients using a time-reversed, exponentially weighted, future sliding equivalent of the signal, wherein the correlation coefficients are determined using pre--existing values of the correlation coefficients determined in a previous iteration, a current sample of the signal and at least two consecutively previous samples of the signal; (b) periodically determining at least the second auto-regressive coefficient modelling the signal using the correlation coefficients; and (c) recognizing the presence of the tone based on the value of the second auto-regressive coefficient.
Patent CA-2271494-A1 (CA)
Inventor: SARDA DEEPAK P
IPC: H04M3/22
Filed: 1999-05-11
Abstract: A method and apparatus for classifying signals into a multiplicity of signal classes which employs discriminant functions of low-complexity discriminant variables that are computed directly from the passband signal. One possible discriminant variable is the central second-order moment, normalized with respect to signal power, of the result of applying a nonlinear operation, such as rectification, to the passband signal being classified. Other possible discriminant variables are the lags of the autocorrelation sequence of the passband signal, normalized. with respect to the signal power.  The discriminant functions can be linear or quadratic functions of the discriminant variables. The accuracy of the classification functions is maximized by employing discriminant functions that are selected to minimize, in a statistical sense, the probability of making erroneous classification decisions. The method can be applied to the problem of classifying voiceband data (VBD), facsimile (FAX), native binary data, and speech on a 64 Kbps digital channel. The method may be implemented using exclusively linear or exclusively quadratic discriminant functions of the discriminant variables.  Hybrid two-stage systems may be employed to reduce the computational requirements at the cost of an acceptable loss in classification accuracy with respect to a classifier that uses only purely quadratic discriminant functions. In such a hybrid system, the first stage employs linear discriminant functions to make classification decisions into a smaller number of possible preliminary signal classes. The decisions of the first stage are then refined by a second stage that uses nonlinear discriminant functions such as quadratic or pseudo-quadratic functions. The second stage of a hybrid classifier then assigns the signal into a larger number of possible classes than does the first stage of the classifier alone.

Title: Process for producing aluminium alloy sheet
Inventor: GUPTA ALOK KUMAR
IPC: C22F1/04
Filed: 1998-02-17
Abstract: A process of producing an aluminum alloy sheet product suitable for forming into automotive parts and exhibiting reduced roping effects. The process involves producing an aluminum alloy sheet product by direct chill casting an aluminum alloy to form a cast ingot, homogenizing the ingot, hot rolling the ingot to form an intermediate gauge product, cold rolling the intermediate gauge product to form a product of final gauge, and subjecting the final gauge product to a solutionizing treatment by heating the product to a solutionizing temperature, followed by a pre-aging step involving cooling the product to a coiling temperature above 50 ~C, coiling the cooled product at the coiling temperature, and cooling the coiled final gauge product from the coiling temperature above 50 ~C to ambient temperature at a rate less than about 10 ~C  per hour to improve T8X temper characteristics of the product. Additionally, a batch anneal step is carried out on the intermediate gauge product or at an intermediate stage of the cold rolling to reduce or eliminate roping tendencies of the alloy sheet product. To maintain a high T8X response, the alloy used in the process has the following composition: 0.4 to 1.1 % by weight magnesium; 0.3 to 1.4 % by weight silicon; 0 to 1.0 % by weight copper;  0 to 0.4 % by weight iron; 0 to 0.15 % by weight manganese; 0 to 0.15 % weight naturally-occurring impurities (collective total); and the balance aluminum.  The invention also relates to a sheet alloy product exhibiting reduced roping effects produced by the indicated process.
