Title: Systeme et procede de dessin tridimensionnel
Inventor: KROITOR ROMAN B
IPC: G06T15/00
Filed: 1996-11-22
Abstract: Procédé permettant de produire des images dont l'aspect est celui de surfaces tridimensionnelles complexes quand on les visualise au moyen d'un système de visualisation stéréoscopique, en utilisant seulement une quantité minimum de données servant à définir les images. On dessine les contours stéréo d'une surface tridimensionnelle complexe au moyen d'un système de dessin informatique tridimensionnel et d'un dispositif d'entrée à trois axes. On visualise le dessin au moyen d'un système de visualisation stéréoscopique en utilisant, par exemple, un écran cathodique sur lequel les images de l'oeil gauche et de l'oeil droit sont multiplexées dans le temps en champs séquentiels et en volets à cristaux liquides synchronisés avec l'écran cathodique. Le fait de dessiner des boucles fermées dans l'espace, de remplir de couleur ces boucles fermées et de dessiner un nombre minimum d'autres contours stéréo, permet de créer une image dont l'aspect définit une surface tridimensionnelle complexe. L'image crée une perception mentale de la totalité d'un objet plein en ne fournissant à l'oeil de l'observateur que les repères minimum nécessaires au cerveau pour créer des objets stéréo présentant des surfaces complexes, en s'appuyant sur l'étape de traitement neural chez l'homme dans laquelle les images que l'oeil voit sont codées en repères stéréo similaires. Le traitement normal de l'image effectué par le cerveau se substitue, en effet, au traitement mathématique complexe des systèmes de l'état actuel de la technique, afin de créer des objets perçus en tant que volumes et surfaces tridimensionnels. Ceci permet d'éliminer la conception et les calculs demandés par les systèmes actuels pour produire une description graphique totalement informatique de l'objet et de limiter considérablement la durée nécessaire au dessin d'objets tridimensionnels, ainsi que les nécessités de traitement des images traitées de façon informatique, les artistes, de ce fait, pouvant créer des images tridimensionnelles d'une manière aussi simple et intuitive qu'on a créé dans l'histoire des images à deux dimensions sur des surfaces à deux dimensions.

Title: Cache address generation
Inventor: EICKEMEYER RICHARD JAMES
IPC: G06F12/10
Filed: 1998-06-11
Abstract: A cache system provides for accessing set associative caches with no increase in critical path delay, for reducing the latency penalty for cache accesses, for reducing snoop busy time, and for responding to MRU misses and cache misses. The cache array is accessed by multiplexing two most-recently-used (MRU) arrays which are addressed and accessed substantially in parallel with effective address generation, the outputs of which MRU arrays are generated, one by assuming a carryin of zero, and the other by assuming a carryin of one to the least significant bit of the portion of the effective addressed used to access the MRU arrays. The hit rate in the MRU array is improved by hashing within an adder the adder's input operands with predetermined additional operand bits.

Patent CA-2255786-A1 (CA)
Title: Semi-frozen food product producing machine
Inventor: VOGEL JAMES D
IPC: A23G9/22
Filed: 1998-12-14
Abstract: The present invention includes a dual purpose carbonator/blending bottle connected to a source of beverage syrup, a source of potable water and to a source of pressurized carbon dioxide gas. The dual purpose bottle is retained within an ice bank water bath tank. A pair of ratio valves provide for metering the water and syrup at a desired ratio. The mixed beverage first flows through a serpentine coil, also located in water bath, and then flow into the dual purpose bottle. A refrigeration system provides for cooling an evaporator located in the water tank for forming the ice bank thereon. The carbonated beverage then flows from the bottle into a freeze cylinder. The freeze cylinder also includes a further evaporator coiled around an exterior perimeter thereof. The freeze cylinder evaporator is connected to and cooled by the same refrigeration system that cools the evaporator in the water bath tank. A scraping mechanism within the cylinder provides for scraping frozen beverage from the inner surface of the cylinder.  A control mechanism provides for controlling the refrigeration system and the cooling of both evaporators. The beverage is therefore pre-cooled to a temperature just above its freezing point before delivery to the freeze cylinder. Thus, less cooling power is needed to reduce the beverage to a frozen state. The present invention utilizes a method of controlling the operation of the refrigeration system and the cooling of both evaporators thereof. The control system provides for directing refrigerant to one or the other of the evaporators as is most efficient so as to avoid short cycling or pressure build up. The present invention uses a control strategy that can more accurately maintain a pre-selected temperature differential between the inlet and outlet temperatures of the evaporators. The control algorithm utilizes a proportional integral differential control approach that safely permits a much narrower temperature difference so that a greater length of each freeze cylinder evaporator can be utilized for efficient heat transfer cooling.

Patent CA-2267513-A1 (CA)
Title: Processing image data
Inventor: ARBEZ PATRICK
IPC: H04N9/75
Filed: 1999-03-30
Abstract: Image frames are stored as a plurality of pixel values. An image frame is viewed in which a perceived object (301) is to be distinguished from the remainder of the image frame. Input signals identify control positions in proximity to the boundary of said object. Pixel values are compared around each of the control positions to define a local colour transition. Colour transitions for the whole object are then produced by a process of interpolation. In this way, a process similar to chroma-keying may be performed without the need to record a foreground object against a specific type of background object. The chroma-keying process is performed locally with respect to a local colour transition. This results in local control signals being produced and control signals for the whole object are then produced by a process of interpolation.
