Abstract: An idealized stochastic screen is characterized by all of the predominant color dots (black or white) uniformly distributed. The present invention seeks to approach this optimization by iteratively selecting pairs of threshold levels in the screen matrix, and measuring the approach to the idealized stochastic screen. The threshold values are then swapped in position to determine whether the swap improves the measurement or not. If it does, the swap is maintained. The process is iterated until the desired result is obtained.

Abstract: Surgical method and apparatus (12) for resectioning tissue (210), preferably lumenal tissue (208), with a remaining portion of an organ being anastomosed with staples or other fastening means, preferably endolumenally. The apparatus may be inserted via a naturally occurring body orifice or a surgical incision and then advanced using either endoscopic or radiological imaging guidance to an area where surgery is to be performed. Under endoscopic or diagnostic imaging guidance the apparatus is positioned so tissue (208, 210) to be resected is manipulated into an inner cavity of the apparatus. The apparatus then cuts the diseased tissue after stapling and retains the diseased tissue within the apparatus. The rent resulting in a border of healthy tissue is anastomosed with surgical staples.

Abstract: For automated visual range measurement by a LIDAR system, a distance measuring range is first determined through repeated evaluation of a voltage level U(R) which indicates the intensity of a threshold value. After random initialization of a start value, the start value is then replaced each time with a new mean visual range, resulting in iterative improvements, and the mean visual range in the determined range is then displayed automatically as soon as the visual range lies within the measuring range of the LIDAR system. Using the Klett method, the accuracy can be determined with the aid of a breaking-off criterion in the form of a threshold value with respect to a deviation percentage between a new and a previous calculation. With this method the deviation can be identified to an order of magnitude of about 10%.

Abstract: A control valve assembly for flushing a sanitary fixture includes a burst valve for supplying flush water flow at the beginning of a flush cycle and an independently controlled bypass valve for providing trap reseal flow after the burst valve closes. The burst valve includes a timing sleeve cooperating with a lifting piston to define a timing chamber communicating with inlet pressure through an orifice. A piston collar cooperates with the lifting piston to define the bypass valve. A lifting chamber defined between the body and the lifting piston communicates with the outlet through a metering valve assembly. Actuation of the metering valve assembly empties the lifting chamber and lifts the timing sleeve, opening the burst valve. The burst valve is closed when the timing chamber fills at a rate controlled by the orifice. The bypass valve is maintained open by pressure differential across the bypass valve to supply trap reseal flow until the metering valve assembly recloses.

Abstract: By recognizing that it is not necessary to identify a synchronization failure immediately when the failure occurs, but rather not until the failure results in a detectable difference, the method and system described herein can distinguish between Cell Delay Variation (CDV) and loss of synchronization. Because CDV will have a larger effect on the stability than a failure of the frequency recovery system at the precise moment of the failure, a synchronization failure cannot usually be distinguished from CDV for several minutes or hours, depending upon the stability of the reference clock. The present invention monitors a fill level of a play-out buffer in the ATM network, and attempts to determine if a variation in the fill level is linear with time, which is indicative of a synchronization failure. Upon detecting such a failure, the method of the present invention switches to an adaptive method for frequency recovery. If the variation in the fill level of the play-out buffer is not linear, but an underflow/overflow (or slip) has occurred, then the method of the present invention can inform an intelligent buffer control that the underflow/overflow is not due to the presence of a synchronization failure, which enables the intelligent buffer controller to take appropriate action.

Granted: 2004-07-27
Abstract: A method for cascade, closed loop control of multiple operating parameters f or an extrusion blow molding machine having multiple accumulators is disclosed. The method provides closed loop control of the ra m back pressure during refill, along with the closed loop adjustment of the pressure set points for "slave" accumulators based on a comparison of ram positions with that of a "master" accumulator. For systems that supply each accumulator with a separate extruder, the rotational speed of the extruder screw is the controlled operating parameter during refill. With respect to extrusion of the parisons, there is closed loop control of the ram velocity in conjunction with adjustment of the velocity set points for the slave accumulators based on a comparison of ram positions with that of the master accumulator.

Abstract: L'invention concerne un procédé pour couper ou massicoter des objets plats qui sont acheminés en continu dans le sens d'acheminement (F), sensiblement parallèlement à leurs surfaces principales, le long de lignes de découpe parallèles au sens d'acheminement (F). Les objets sont guidés entre une première et une seconde arête de coupe (SK1 et SK2) et sont coupés par un mouvement relatif des deux arêtes de coupe. A cet effet, la première arête de coupe (SK1) est disposée par exemple stationnaire dans un plan d'appui des objets et pour une opération de coupe, la seconde arête de coupe (SK2) est guidée devant la première arête de coupe, de manière qu'au moins le point de coupe situé sur la seconde arête de coupe (SK2) présente une composante de vitesse dans le sens d'acheminement, qui soit égale à la vitesse d'acheminement, et une composante de vitesse perpendiculaire au plan d'appui. On y parvient de préférence par un mouvement de pivotement de la première arête de coupe (SK2) autour d'un pivot (M) situé au-dessus de la surface d'appui, la distance (y) et la vitesse de pivotement ( omega ) étant adaptées en fonction l'une de l'autre et de la vitesse d'acheminement. Il est avantageux que plusieurs secondes arêtes de coupe (SK2) soient disposées en étoile dans un plan perpendiculaire au pivot (M) et que la configuration des secondes arêtes de coupe (SK2) tourne autour du pivot (M) à une vitesse constante ( omega ).
