Title: A method of optimal controller design for multivariable predictive control utilizing range control
Inventor: LU ZHUXIN JOSEPH
IPC: G05B13/02
Filed: 1996-04-01
Abstract: A process control system which includes at least one manipulated variable and at least one controlled variable, provides a method for robust control of a process. Predetermined constraints of the manipulated variables and the present values of the manipulated variables are obtained. The controller is loaded with parameters which define an optimal controller, the parameters being calculated off-line. To determine the parameters a single min-max statement is defined for a worst case model of the process which operates in conjunction with a best case controller. The single min-max statement is converted to a corresponding canonical expression in the form of a minimization problem, the resultant solution of the minimization problem being the parameter. New values are calculated for the controlled variables for a predetermined number of points in the future, such that the values of the controlled variables are within the predetermined range thereby obtaining an optimal robustness of the resultant controller. The manipulated variables are also calculated to be within predetermined constraints, and the controlled variables to fall within a predetrmined range when controllable. From a plurality of solutions, a most robust solution is selected. Then the manipulated variables are adjusted to cause the process control system to drive the values of the controlled variables to the calculated values.

Filed: 1998-03-23
Abstract: THE KNOWN PROCEDURES FOR THE HOME MADE PREPARATION OF FERMENTED BEVERAGES SUCH AS BEER AND WINE, ARE BASED ON THE SEPARATION OF THE DRINKABLE LIQUID  FROM      THE SOLIDS PRODUCT OF THE PRECIPITATION OF SOME OF THE INGREDIENTS . THIS      SEPARATION IS ACHIEVED BY SIPHONING THE BREWING MIX FROM ONE CONTAINER TO      ANOTHER. THE KNOWN METHODS REQUIRE TO PERFORM THE SEPARATION PROCESS AT   LEAST TWO TIMES THROUGHOUT THE BREWING TIME, FOR IT IS FUNDAMENTAL TO REDUCE      THE CONTACT OF DECOMPOSED SEDIMENTS WITH THE MIX IN ORDER TO AVOID THE    SPOILAGE OF THE BATCH.      THE PRESENT INVENTION SIGNIFICANTLY EASES THE PROCESS OF HOME BREWING BY SIMPLIFYING THE REMOVAL OF UNDESIRABLE SOLIDS, MINIMIZING THE RISKS OF  EXTERNAL     CONTAMINATION AND REDUCING HOURS OF LABOUR WITHOUT MODIFYING THE RESULT OF      THE BIOCHEMICAL REACTIONS INHERENT TO FERMENTED BEVERAGES.      THIS INVENTION CONSISTS OF A SINGLE FERMENTING CHAMBER, A LID; A VALVE      ATTACHED TO THE BOTTOM OF THE FERMENTING CHAMBER, A REMOVABLE COLLECTING    PIPE AND A POURING HOSE. AFTER THE INGREDIENTS ARE PLACED IN THE FERMENTING  CHAMBER, THE CHAMBER IS THEN COVERED WITH A HERMETICAL LID. THE VALVE IS LEFT  OPEN AS THE SEDIMENTS SETTLE IN THE COLLECTING PIPE. AT THE DISCRETION OF THE   BREWER THE VALVE MAY BE OPENED OR CLOSED AT ANY TIME THROUGHOUT THE BREWING  PROCESS, ENABLING THE SAFE DETACHMENT OF THE COLLECTING PIPE AND THE DISPOSAL   OF THE SEDIMENTS ACCUMULATED INSIDE OF IT. THE DISPOSAL PROCEDURE MAY BE REPEATED AS MANY TIMES AS NECESSARY, UNTIL THE MIX IS READY FOR BOTTLING.

Patent CA-2232018-A1 (CA)
Title: Electrosurgical generator with adaptive power control
Inventor: GINES DAVID LEE
IPC: H03L5/02
Filed: 1998-03-11
Abstract: An electrosurgical generator has an output power control system (10) that causes the impedance of tissue (14) to rise and fall in a cyclic pattern until the tissue (14) is desiccated. The advantage of the power control system (10) is that thermal spread and charring are reduced. In addition, the power control system (10) offers improved performance for electrosurgical vessel sealing and tissue welding. The output power is applied cyclically by a control system with tissue impedance feedback. The impedance of the tissue follows the cyclic pattern of the output power several times, depending on the state of the tissue (14), until the tissue becomes fully desiccated. High power is applied to cause the tissue (14) to reach a high impedance, and then the power is reduced to allow the impedance to fall. Thermal energy is allowed to dissipate during the low power cycle. The control system is adaptive to tissue in the sense that output power is modulated in response to the impedance of the tissue.

Patent CA-2232194-A1 (CA)
Title: Figure location detecting system
Inventor: MONDEN AKIRA
IPC: F27D99/00
Filed: 1998-03-16
Abstract: A figure location detecting system is designed to detect a location of a first figure (e.g., search fingerprint) within a second figure (e.g., file fingerprint). Particularly, the system is designed to correctly match characteristic points of the first figure with characteristic points of the second figure even if the first figure contains a plenty of similar characteristic points whose characteristics are similar with each other and/or even if the first figure is (partially) distorted. Herein, the system creates matching characteristic point pair candidates each corresponding to a pair of a first characteristic point, corresponding to one of the characteristic points of the first figure, and a second characteristic point corresponding to one of the characteristic points of the second figure. The matching characteristic point pair candidates are created on the basis of relative characteristics which are calculated for proximity characteristic points which exist in proximity to the first and second characteristic points respectively. Then, the system narrows down the matching characteristic point pair candidates to matching characteristic point pairs by removing wrong  matching characteristic point pair candidates, each of which is detected as a wrong match in consideration of a matching situation of the proximity characteristic points. Coordinate matching parameters are produced with respect to each of the matching characteristic point pairs.          Thus, the system outputs most concentrated coordinate matching parameters which values of the coordinate matching parameters sequentially produced concentrate in most frequently.

Abstract: Linerless labels are cut or burst from a web (W) by passing the web (W) through infeed and outfeed pairs of rolls (12, 14; 30, 32) with a separator device located therebetween. Each roll pair includes a friction surface for engaging the slick smooth surface (S) of the web and another roll with a silicone elastomeric or plasma-coated surface for engaging substantially without gripping the exposed adhesive side (A) of the linerless label web (W).  In the cutting mode, a rotary blade severs (42) the web against a fixed blade (40) to form the label. The infeed rolls (12, 14) are backed up after each cut to break the adhesive bond between the web (W) and the fixed blade (40) and then reverse to advance through the cutting position and into the outfeed rolls (30, 32) for a subsequent cutting operation. The outfeed rolls (30, 32) continue to advance the cut linerless label to a receiving station. In a bursting mode, the web (W) is perforated and a roller breaker bar (80) is disposed between the infeed and outfeed rolls (12, 14; 30, 32) to break the web (W) along the perforations to form the linerless label.

Title: Conjugation of c-myc antisense oligonucleotides with cholesterol to significantly enhance their inhibitory effect on neointimal hyperplasia
Inventor: FLESER ANGELICA
IPC: A61K38/00
Filed: 1996-10-18
Abstract: Antisense oligonucleotides have recently been proposed as a pharmacological approach to prevent neointimal hyperplasia following balloon angioplasty. This study reports the significant enhancement on in vivo restenosis prevention conferred by the conjugation of cholesterol to a c-myc antisense oligomer when compared to a non conjugated oligonucleotide. The inhibitory potential of the conjugate was increased 2.4-fold, reaching a reduction of intimal hyperplasia of 84.7 % vs. control arteries. Enhancement of hyperplasia prevention may be related to the 2.7-fold increase in oligomer vascular retention conferred by the cholesterol moieties, sufficient to cover a significant portion of the proliferation window that typically follows balloon angioplasty.
