Granted: 2000-05-16
Abstract: A communication system (100) that includes a base unit (101) and a subscriber unit (e.g., 103) employs a method (400) and apparatus (101) for mitigating interference (135) therein. The base unit (101) receives an uplink communication signal from the subscriber unit (103) at an uplink frequency and conveys a downlink communication signal to the subscriber unit (103) at a downlink frequency. Upon receiving (403) an uplink communication signal from the subscriber unit (103), the base unit (101) determines (405) a quality metric for the uplink frequency. When the quality metric is below a quality threshold (407), the base unit (101) and the subscriber unit (103) transfer (415) the communication signal to an alternate uplink frequency, while the downlink frequency remains unchanged.

Granted: 1999-08-17
Abstract: A method for efficiently and accurately producing filter coefficients for wavefield extrapolation which is particularly useful for migrating seismic data using a multiprocessor  parallel  computer as  provided.  In 3D seismic migration, the techniques have been  developed for 3D  processing using  ID  extrapolation filters.  The present  invention uses a  Remez-type  approximation  for developing such extrapolation filters which increases image quality or reduces processing  time, or both. Additionally, the method provides an  automated  method  for  producing such extrapolation filters which is  particularly  useful in parallel seismic migration  because of the  large  number of  extrapolation filters which  must be  produced.  The automated method of generating filters  sets  a frequency transition band where the amplitude is specified  to  be monotonically decreasing which insures stable filter design.

Granted: 2002-06-25
Abstract: Une machine à sécher rotative avec aération est conçue pour pouvoir souffler de l'air dans une couche de matériau dans un cylindre, ou pour souffler de l'air sur la surface d'une couche de matériau. L'air circule par une conduite à air (21) allant d'un boîtier de sortie (12) via un cylindre rotatif (10) dans la direction axiale de celui-ci, jusqu'à un boîtier d'entrée (11). La conduite à air (21) comprend une pluralité d'éléments de conduite principaux (22, 23, 24), reliés axialement et disposés dans le cylindre (10), les diamètres des éléments de conduite principaux diminuant graduellement depuis le côté sortie en direction du côté entrée. Comme le diamètre de l'élément de conduite principal (24) le plus proche de l'entrée est le plus petit, le diamètre d'une ouverture (32) d'une plaque de répartition (31), sur le côté entrée du cylindre (10), peut également être choisi petit. Comme la largeur radiale de la plaque de répartition (31), sur le côté entrée, peut être choisi grande, on peut empêcher le débordement du matériau brut introduit depuis l'ouverture (32), sur le côté entrée. Comme le diamètre de l'élément de conduite principal (22) passant par une ouverture (34) d'une plaque de répartition (33), sur le côté sortie, est le plus élevé, l'espace libre disponible à l'ouverture (34), sur le côté sortie, diminue. Toutefois, la plaque de répartition (33), sur le côté sortie, comprend des volets (35), comme cela est nécessaire, qui sont disposés d'une manière circonférentielle et espacée, pour que l'évacuation de l'air se fasse, non seulement par l'espace libre disponible de l'ouverture (34), mais également par l'espace libre entre les volets (35). Ceci permet d'augmenter le volume d'air évacué et on peut ainsi assurer une capacité qui n'est pas inférieure au double de la capacité d'une machine à sécher rotative classique, ayant un cylindre du même volume.

Abstract: Method and apparatus by which relative displacement between molten solder and a terminal pin is caused and a coating formed on an end portion of a coil on the terminal is removed by the molten solder, and thus the terminal portion is firmly soldered to the terminal pin after removal of the coating.  In contrast, in conventional soldering methods, when a terminal pin, which is provided on a terminal base and has an end portion of a coil wound therearound, is dipped in molten solder contained in a solder bath, there is no relative displacement between the pin and the molten solder.  Thus, sometimes the coating formed on the coil still remains, so that a complete soldering connection between the terminal pin and the coil is not sufficiently achieved.  In accordance with the method and apparatus of the present invention, a full connection therebetween is achieved, and the reliability thereof is enhanced.
