Abstract: Multiported register files for use in storing coefficients in adaptive FIR filters. incorporate computational ability, e.g., the ability to perform computation on coefficient values or derivatives thereof, or to control the operations performed thereon. For example, a multiported register file may incorporate an overflow/underflow detection and/or saturation unit. Also, the multiported register file may incorporate a special encoder to speed up the multiplication process, e.g., the so-called "Booth" encoder. Likewise, the multiported register file may incorporate a converter for changing the representation of the coefficients, e.g., a two's complement to sign-magnitude converter. All computation performed in the multiported register file is performed outside of the critical path of the filtering or of the coefficient updating. Using such improved multiported register files, adaptive FIR filters can be constructed which operate faster, and with lower power consumption.

Title: Systeme et procede de generation de valeurs de pixels dans une image selon des methodologies strictement deterministes destinees a generer des points echantillons
Inventor: HERKEN ROLF
IPC: G06T15/50
Filed: 1997-06-25
Abstract: L'invention concerne un système graphique informatique générant des valeurs de pixels dans une représentation d'objets dans une scène, à l'aide de séquences strictement déterministes à faible divergence, telles que des séquences de Halton servant de points échantillons destinés à calculer des entiers qui sont utilisés pour simuler un nombre de techniques graphiques informatiques. Ce système comprend: (1) des ombres douces générées pour des scènes éclairées par une source lumineuse d'une étendue infinie telle qu'un disque, opposée à une source lumineuse ponctuelle; (2) la simulation de la profondeur de champ; (3) un flou de l'objet mobile; (4) une instabilité. Ce système graphique informatique utilise la séquence à faible divergence: (1) en relation avec des ombres douces pour générer des points échantillons sur l'étendue de la source lumineuse éclairant la scène; (2) en relation avec la simulation de profondeur de champ pour générer des points échantillons sur la surface de la lentille entre la scène et l'image; (3) en relation avec le flou du mobile pour générer des points échantillons sur un intervalle de temps dans lequel le flou doit être simulé pour déplacer des objets dans la scène; et (4) en relation avec l'instabilité pour générer des points échantillons instables sur une image ou une pluralité de pixels contigus. A la différence des nombres aléatoires utilisés en relation avec la technique de Monte-Carlo, les séquences à faible divergence permettent une répartition uniforme des points échantillons dans un intervalle spatial ou temporel suivant le cas, ce qui réduit l'erreur dans l'image pouvant entraîner une agglomération de ces points échantillons qui peut se produire dans la technique Monte-Carlo. Cette invention facilite notamment une génération d'images de meilleure qualité lorsqu'on utilise le même nombre de points échantillons pour un effort de calcul identique à celui de la technique Monte-Carlo.

Abstract: A method and structure for forming a small building includes a continuous curved wall forming a semi-arcuate arch, the wall comprised of lightweight cellular material such as foamed blocks. The blocks may be identical and interchangeably secured in place by adhesive to form the wall, so that the arch is easily constructed. The arched wall comprises both the longitudinal sides and the top of the structure. In addition, the structure includes an outer skin which covers the entire exterior of the arched wall. The outer skin is both a weatherproof layer and a tension member to apply a compressive force uniformly to the outer surface of the arched wall and significantly augment the load strength of the arch, resulting in a structure that is made very strong with a minimum mass of material. The method of the invention includes the steps of providing a plurality of cellular blocks of expanded foam plastic or the like, each block defining an angular increment of an arched wall and having a length that is an incremental portion of the length of the arched wall. Courses of blocks are laid in laterally spaced arrangement and adhered in place until the arched wall is completed.   Alternatively, incremental arches may be constructed horizontally and tilted upwardly into abutting, adjacent relationship. Thereafter, an outer skin is formed over the exterior surface of the arched wall and tensioned to compress the arched wall.

Title: System for accurately determining missile vertical velocity and altitude
Inventor: SOSINSKI STEPHEN V
IPC: G01S13/935
Filed: 1998-12-03
Abstract: A system (30) for determining a missile kinematic property. The inventive system includes a radar system (36) for obtaining radar range measurements (34). An inertial reference unit (40) tracks changes in missile acceleration without the use of the radar range measurements and provides a signal (38, 42) in response thereto. An altitude Kalman filter (32) and a subtractor circuit (48) are used to combine the signal (38, 42) and the radar range measurements (34) to provide an accurate estimate (50) of the property. In a specific embodiment, the kinematic property includes missile vertical velocity and missile altitude. A radar system (36) supplies radar range information (34) to the Kalman filter (32). A loop (52) from the Kalman filter (32) to the radar system (36) facilitates estimating the radar range measurements (34) when invalid radar range measurements are provided by the radar system (36). The Kalman filter (34) is a two state filter, one state corresponding to missile altitude, and the other state corresponding to missile vertical velocity bias error in the inertial reference unit's (40) velocity measurements (42). In the illustrative embodiment, the Kalman filter (32) combines radar pseudo-measurement estimates of missile altitude with estimates (38) of missile altitude obtained from the inertial reference unit (40) and provides an output signal (46) representative of an accurate missile altitude estimate in response thereto. The Kalman filter (32) includes a velocity bias output (44) which provides an estimate of the error in a velocity measurement (42) obtained from inertial reference unit (40) to the subtractor circuit (48). The subtractor circuit (48) subtracts the estimate (44) of the bias error from the velocity measurement (42) and provides the missile velocity estimate (50) in response thereto.
