Title: Lcd addressing system
Inventor: SCHEFFER TERRY JAMES
IPC: G09G3/20
Filed: 1992-02-06
Granted: 1999-04-13
Abstract: A method and apparatus for addressing faster responding liquid crystal panels (LCDs) so that video rate, high information content LCDs having time constants on the order of 50ms or less, are perceived as having brighter bright states and darker dark states by limiting peak voltage levels across the pixels.  A first set of LCD electrodes are continuously driven with signals each comprising a train of pulses that: are periodic in time; have a common period T; are independent of the information to be displayed; and are preferably orthonormal.  A plurality of column signals are generated from the collective information state of the pixels defined by the overlap with a second electrode pattern.  Each column signal is proportional to the sum obtained by considering each pixel in the column and adding the voltage of that pixel's row at time t to the sum if the pixel is to be "off" and subtracting the voltage of that pixel's row at time t from the sum if the pixel is to be "on".  If the row signals only switch between two voltage levels, the sum may be represented as the sum of the exclusive or (XOR) products of the logic level of the amplitude of each row signal times the logic level of the information state of the pixel corresponding to that row.       Hardware implementation comprises an external video source, a controller that receives and formats video data and timing information, a storage means for storing display data, a row signal generator, a column signal generator, and at least one LCD panel.  Alternative embodiments provide gray scale shading and circuits to reduce the magnitude of the column signals, as well as the number of column voltage levels required to generate a displayed image.

Title: Duplicated-memory synchronization arrangement
Inventor: PASHAN MARK ALLEN
IPC: G06F11/16
Filed: 1992-05-19
Granted: 1997-02-04
Abstract: A shared-buffer-memory-based ATM switch module (1) is duplicated (2) and operates in active-standby mode for fault-tolerance. Following failure and repair of a module, buffer memory (12) contents of the two modules are resynchronized as follows. At the time of commencing the synchronizing, contents of the memory of the standby, repaired, module are cleared, all writes to the active module's memory also commence to be made to the standby module's memory, and track begins to be kept of overwriting of the contents of the active module's memory that existed at the time of commencing the synchronizing. This is done by a function (FIG. 4), whichsets a flag (64) in a queue-length-counter monitor (60) for every active-module queue-length counter (200) that reaches a count of zero to indicate that its corresponding buffer-memory queue (100) has been emptied. When all monitor flags have been set in response to each queue-length counter having reached a count of zero, it indicates that the original contents of the active module's memory have been overwritten and the memories again have identical contents, and consequently that resynchronization of the two memories has been achieved and fault-tolerancehas been re-established.

Title: Process and catalyst for producing isotactic polyolefins
Inventor: EWEN JOHN A
IPC: C08F4/6592
Filed: 1992-09-08
Granted: 2003-06-24
Abstract: This invention is for a metallocene catalyst component useful in preparing isotactic polyolefins, a catalyst system using this component and a process for polymerizing olefins using the catalyst component. The catalyst component consists of a bridged metallocene in which one of the cyclopentadienyl rings is substituted in a different manner from the other ring. One of the cyclopentadienyl ligands contains a bulky group in one and only one distal position and the other cyclopentadienyl ligand has bilateral or pseudobilateral symmetry. There is a steric difference between the two Cp rings.      The catalyst component is a stereorigid metallocene described by the formula:      R" (CpR n)(CpR'm)MeQ k wherein each Cp is a cyclopentadienyl or substituted cyclopenta-dienyl ring: each R n and R'm is a hydrocarbyl radical having 1-20 carbon atoms; R" is a structural bridge between the two Cp rings imparting stereorigidity to the Cp rings. Me is a transition metal; and each Q is a hydrocarbyl radical or is a halogen. R'm is selected so that (CpR'm) is a sterically different substituted cyclopentadienyl ring than (CpR'n). The use of a metallocene catalyst component with sterically different cyclopentadienyl rings in which one and only one of the distal positions of the cyclopentadienyl rings has a bulky group as a substituent produces isotactic polymer.

Abstract: Champ magnétique (202, 302), permettant de confiner le plasma, généré dans une zone de pulvérisation (105, 106) d'une cible de pulvérisation (40) avec une ligne de champ critique (202b, 302b) qui détermine la forme du plasma (204, 304). La ligne de champ critique est progressivement aplanie pendant la durée de vie de la cible au fur et à mesure qu'elle s'érode. L'aimant (51, 52) comprend de préférence des pôles (57, 61, 65) espacés autour de la partie de la cible située sous la zone de pulvérisation afin de créer un champ magnétique qui s'aplatit au fur et à mesure qu'il perd de son intensité. L'alimentation stabilisée (122) maintient un niveau stable qui est augmenté au fur et à mesure que la cible s'érode afin de conserver un taux de dépôt constant. La tension de l'alimentation électrique est maintenue à une valeur égale ou supérieure à un niveau constant en diminuant progressivement le courant qui alimente un électro-aimant (52, 54) afin de réduire progressivement l'intensité du champ et de l'aplatir. La présente invention permet d'élargir le sillon de la cible et d'accroître la quantité de plaquettes enduites par la cible durant sa durée de vie.

Title: Methods for speech quantization and error correction
Inventor: HARDWICK JOHN C
IPC: G10L19/08
Filed: 1991-12-04
Granted: 2005-03-22
Abstract: The redundancy contained within the spectral amplitudes is reduced, and as a result the quantization of the spectral amplitudes is improved. The prediction of the spectral amplitudes of the current segment from the spectral amplitudes of the previous is adjusted to account for any change in the fundamental frequency between the two segments. The spectral amplitudes prediction residuals are divided into a fixed number of blocks each containing approximately the same number of elements. A prediction residual block average (PRBA) vector is formed; each element of the PRBA is equal to the average of the prediction residuals within one of the blocks The PRBA vector is vector quantized, or it is transformed with a Discrete Cosine Transform (DCT) and scalar quantized. The perceived effect of bit errors is reduced by smoothing the voiced/unvoiced decisions. An estimate of the error rate is made by locally averaging the number of correctable bit errors within each segment. If the estimate of the error rate is greater than a threshold, then high energy spectral amplitudes are declared voiced.
