Abstract: Un système et un procédé d'estimation de la vitesse pour réseau de radio cellulaire comportent un certain nombre d'unités d'estimations de vitesse (14-20). Chaque unité comprend une fenêtre de calcul de moyenne (24) de durée différente, une mémoire tampon (26) et un calculateur de variance (28). La durée de chaque fenêtre est équivalente au temps que prend une unité mobile pour parcourir une distance de 20 longueurs d'ondes du signal reçu à une vitesse particulière. Un signal d'entrée est appliqué aux unités. La durée de la fenêtre détermine la signification des composantes à évanouissement rapide du signal se rapportant à la vitesse de l'unité mobile. Quand la moyenne d'une fenêtre est pratiquement constante, on peut en déduire que la vitesse correspondant à cette fenêtre est réalisée ou dépassée. Une logique de décision (30) est conçue pour interroger les sorties des calculateurs de variance pour calculer une indication d'estimation de vitesse.

Abstract: A thin film electrode (10) for a rechargeable (secondary) battery is prepared by electron beam deposition of LiMn2O4, Li-CoO2, or LiNiO2 on a smooth, amorphous substrate surface (14) and in situ annealing of the deposited lithium composition at a temperature below about 500 °C. The amorphous nature of the substrate surface prevents epitaxial growth or ordered orientation of the minute composition crystallites thus formed. The finely granular structure of the resulting electrode thin film (16) presents abundant surface area that enables a 4V battery to provide current densities in the range of 500 mic-roamps/cm2. The low annealing temperature enables formation of the electrode structure and subsequent battery assembly directly upon semiconductor devices and integrated circuitry.

The trend in the development of k can be calculated and used to determine if an anomaly exists in the determined value of k.

Title: Insulating cladding panel
Inventor: NONIS ALBINO D
IPC: E04B2/00
Filed: 1993-05-14
Granted: 1997-02-25
Abstract: An insulating cladding panel for an exterior wall of a building is a sheet of insulating material having a plurality of intersecting channels on its interior surface.  The channels are sized and spaced to provide a rapid equalization of pressure across the panel when installed on the wall.  This pressure equalization essentially eliminates the forces promoting water penetration through the panel joints to the wall.  The channels also facilitate the escape of any water which may penetrate the panel system.  The neutralization of the live wind load by the channel system of the panels eliminates the need for supporting members when installing the panels on a wall.

Abstract: A line spectral frequency (LSF) vector quantizer, having particular application in digital cellular networks (DCN), is provided for code excited linear predictive (CELP) speech encoders. The LSF vector quantizer is efficient in terms of bits employed, robust and effective in terms of performance across speakers and handsets, moderate in terms of complexity, and accommodates effective and simple built-in transmission error detection schemes. The LSF vector quantizer employs a minimum number of bits, is of moderate complexity and incorporates built-in error detection capability in order to combat transmission errors. The LSF vector quantizer classifies unquantized line spectral frequencies into four categories, employing different vector quantization tables for each category. Each quantization table is optimized for particular types of vectors. For each category, three split vectorcodebooks are used with a simplified error measure to find three candidate split quantized vectors. The three sets of three split vectors are combined to produce as many as 27 vectors from each category. The quantizer then makes a final selection of optimal category, using a more complex error measure, to achieve the robust performance across speakers and handsets. Split vector quantization follows a two stage constrained search procedure that results in an ordered set of quantized line spectral frequencies that is "close"to the unquantized set with moderate complexity within each category. Effective and simple transmission error detection schemes at the receiver are made possible by the split nature of the vector quantization and the constrained search procedure. Only twenty-six bits are required to encode ten line spectral frequencies.

Abstract: The terminals (P1 and P2) of a test circuit are directly connected to outputs of the transformer secondary windings and to the input of the rectifying circuit so that the test current checks operation of the trip device. A sign detection circuit (10) supplies a processing circuit (9) with the values of the polarities of the rectified currents. The processing circuit (9) comprises means for determining the presence of a test current when the sign of the rectified current comprising the test current remains continuously in the same polarity. A differentiation of the continuous polarity, positive or negative, of the test current enables testing to be carried out with or without earth protection tripping.

Title: Surface treatment for silicon substrates
Inventor: CUNNINGHAM JOHN EDWARD
IPC: H01L21/302
Filed: 1995-04-20
Granted: 1999-01-26
Abstract: A method for desorbing the surface oxide on a silicon substrate is performed by implanting particles such at atomic or ionic hydrogen into the oxide layer on the silicon substrate. The oxide is then removed by breaking the bonds between the silicon and oxygen atoms within the oxide. The bonds may be broken by heating the substrate, for example. The temperature to which the substrate must be raised is substantially less than the temperature required to desorb an oxide layer that has not undergone an implantation step. In one particular example, the particles implanted into the oxide surface are hydrogen ions generated by electron cyclotron resonance.
