Abstract: Un emballage, notamment pour matériaux en vrac, peut comprendre un contenant interne souple qui est renfermé et suspendu dans une structure de levage (11), un conteneur étant positionné autour de la structure de levage (11) et du contenant interne. La structure de levage (11) présente un orifice de sortie (14) qui coïncide avec l'orifice de sortie ménagé dans la base du contenant interne, de sorte que l'on puisse décharger le matériau de ce dernier sans enlever la structure de levage (11). Des sangles de levage (15) peuvent être reliées de façon peu serrée avec des éléments d'accouplement ménagés dans la partie supérieure du contenant interne, de sorte que, lorsque ce dernier est suspendu, son poids et celui de son contenu sont supportés par la structure de levage (11) et non par le contenant lui-même.

Abstract: An intelligent digital beam former (10) in conjunction with a satellite based array antenna (20) provides a plurality of dynamically controllable antenna beams (52) for communication with subscriber units (90) in response to demand for communication services. Geographic portions within the satellite's footprint that have a higher-demand for communication services are dynamically provided additional antenna beams while geographic portions having a lower demand for communication services are provided less antenna beams. When used on a non-geostationary satellite, the digital beam forming coefficients are dynamically adjusted to steer the antenna beams to maintain their ground location. The antenna beams are also shaped to help optimized geographic coverage.

Abstract: A method and apparatus for filtering suspensions of medical and biological fluids, one aspect of which is separating a suspension comprising at least two types of particles (104) and (108) which are differently sized or shaped and in which a first type of red cell particle (104) may be deformable at a relatively lower force and/or faster rate than a second type of white cell particle (108). A filter membrane (100) is provided having pores (102) with substantially precisely dimensioned pore sizes, with the pores (102) being dimensioned to allow passage of the first type of particle (104) without distortion or only minimal distortion and passage of the second type of particle (108) only with substantial distortion. Because the filter membrane (100) has precisely dimensioned pores (102), with spacing between the pores (102) being maintained despite the smaller interval between the pores (102), the porosity of the membrane (100) may be relatively much greater, allowing faster filtration rates while reducing shear exposure time and consequently reducing particle damage. Various methods for preventing clogging of the membrane (100) are also disclosed.

Abstract: A receiver with frequency offset correcting function corrects distortion caused by interference between codes and a frequency offset in received signals. In order to correct the distorsion, a frequency offset correcting circuit (21) corrects the received signals based on an estimated frequency offset value. A first CIR estimating circuit (22) finds an estimated CIR value at a first position based on an already known training sequence in the corrected received signals. A second estimating circuit (24) finds another estimated CIR value at a second position which is different from the first position by updating the estimated CIR value at the first position as an initial value in accordance with an LMS algorithm based on the corrected received signals and a decision value outputted from an equalizer (13). A phase deviation detecting circuit (15) calculates phase deviations based on the estimated CIR values at the first and second positions and an averaging circuit (26) averages the phase deviations and outputs the average phase deviation to a frequency offset correcting circuit (21) as an estimated frequency offset value.

Granted: 2002-02-19
Abstract: A method for providing independent static and dynamic models in a prediction , control and optimization environment utilizes an independent static model (2 0) and an independent dynamic model (22). The static model (20) is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model (22) is trained over a narrow range of data. The gain K of the  static model (20) is utilized to scale the gain k of the dynamic model (22).  The forced dynamic portion of the model (22) referred to as the bi variables  are scaled by the ratio of the gains K and k. The bi have a direct effect on  the gain of a dynamic model (22). This is facilitated by a coefficient modification block (40). Thereafter, the difference between the new value input to the static model (20) and the prior steady-state value is utilized as an input to the dynamic model (22). The predicted dynamic output is then summed with the previous steady-state value to provide a predicted value Y. Additionally, the path that is traversed between steady-state value changes.
