Title: Method of managing slowly changing dimensions
Inventor: CAMPBELL NIGEL ANTHONY
IPC: G06F17/30
Filed: 2001-06-18
Granted: 2006-08-01
Abstract: A method of managing slowly changing dimensions in a dimensional database, such as a dimensional data mart, is disclosed. The method consists of providing a dimension template for each dimension undergoing slow changes, which template assigns a behavior to each column of the dimension table. When a row of dimensional data is to be delivered to the dimension table, the table is searched for a record having the key value of the row of data to be delivered. If such a record exists and if any attributes of the row to be delivered have their values changed compared with the existing record, the table is updated according to the behavior type assigned to these attributes in the dimension template, either by overwriting the existing record with the record to be delivered or by creating a new record or records.

Title: Stopper rod
Inventor: HANSE ERIC
IPC: B22D11/10
Filed: 1999-11-16
Granted: 2009-06-09
Abstract: The present invention concerns a stopper rod whose gas tightness and rigidity are improved. In particular, the stopper rod of the present invention has means for maintaining the compression of the sealing gasket (11, 11') in contact with the annular sealing surface (10) of the body of refractory material when the stopper rod is brought to a high temperature. According to one embodiment of the invention, these means are furnished by a sleeve (12) comprised of a material with a high coefficient of thermal expansion, the dilatation of which maintains the sealing gasket under compression when the stopper rod is brought to a high temperature.

Abstract: L'invention concerne un système de chirurgie au laser dont le système de commande informatique est couplé à un sous-système laser et au siège du patient. Ledit système de commande est couplé au laser via un système d'alignement du laser. Le système de commande peut être couplé au siège du patient via un système d'alignement du patient. Le système de commande envoie un signal nominal de position afin de déplacer le siège du patient, le sous-système laser, ou les deux, de manière à placer le premier oeil du patient sensiblement dans l'alignement de l'axe du faisceau laser. Le système de commande peut envoyer un second signal nominal afin de placer le second oeil du patient sensiblement dans l'alignement de l'axe du faisceau laser. Le système de commande peut comprendre éventuellement un afficheur opérateur et un afficheur assistant. L'afficheur assistant fournit des informations en temps réel à un assistant positionné au niveau d'un poste d'assistant adjacent au siège du patient. Le système de commande peut être programmé pour afficher des zones d'édition de différentes couleurs de manière à donner une indication précise quant aux informations de réfraction de l'oeil. Le système de commande peut comprendre une unité d'entrée opérateur destinée à l'administration d'un traitement ablatif secondaire prédéterminé. Si l'on détermine que le premier traitement ablatif n'a pas complètement éliminé la couche épithéliale sur une zone cible, l'opérateur actionne l'unité d'entrée opérateur en vue de l'administration du traitement ablatif secondaire.

Title: Improved bi-cell chevrons detection color registration system for color printing
Inventor: LOFTHUS ROBERT M
IPC: H04N1/50
Filed: 2001-11-27
Granted: 2005-04-12
Abstract: In color printing with a color registration system for the registration of plural color images on an image bearing surface, such as a photoreceptor belt of a color printer, chevron shaped registration marks are imaged on the image bearing surface, which registration marks correspond to the color images and are sensed by a registration marks sensor as the image bearing surface moves in its process direction. The registration marks sensor has chevron shaped optical sensing areas provided by a matching pair of spaced apart elongated bi-cell detectors in a generally chevron shaped pattern. Each of these spaced apart elongated bi-cell detectors has a parallelogram shaped optical sensing area. That parallelogram shaped sensing area is defined by elongated parallelogram sides extending at the same angle as one leg of the chevron shaped registration marks, and parallelogram ends which are parallel to the process direction, so as to provide higher color registration accuracy.

Abstract: The voice quality of telephone calls is evaluated. A first connection is established between a computerized apparatus and a person acting as a first experimenter, and a second connection is established between the platform and a second experimenter. The first and second connections are interconnected by the computerized apparatus to establish a call between the two experimenters and enable them to converse, the apparatus being cut into the call in order to acquire data about the call. The experimenters' opinions are solicited concerning their perceptions of the quality level they observe during their conversation. The apparatus evaluates consistency of the data collected with the nominal experimental conditions and the nominal quality level associated with the current test. Then, a determination is made as to how the current test is to be carried out as a function of a test plan and of the result of the evaluation. The test plan is set up by specifying nominal conditions for the experiment and nominal quality levels for carrying out the tests, and in collecting data during the tests.
