Title: Incinerator
Inventor: FUTATSUGI TAKEHIKO
IPC: F23J15/04
Filed: 1997-09-05
Abstract: An incinerator comprising a drying chamber (9), a decomposing chamber (12), a combusting chamber (25), a catalytic converter (35), a water vapor condenser (38) and a heat utilising apparatus (40) which are integrated such that combustion air flows along the inside (19) of an insulated exterior wall and a counter flow heat exchange is effected between the air containing dust, and the ash and exhaust gas, wherein base is mixed to burn wastes. Most of the constituent elements may be incorporated in a rotating body. The temperature of exhaust gas is close to the room temperature, and a scrubber can be directly connected or integrated. The discharge of pollutants can be reduced to a very low level. No auxiliary fuel other than the fuel for the initial heating and the pilot light for maintaining the flame is needed to burn even wastes having a water content of 90 % or greater. It is possible to deal with various types of wastes and to adopt various types of incinerators.

Title: Efficient block cipher method
Inventor: SUNDARAM GANAPATHY SUBRAMANIAN
IPC: G09C1/00
Filed: 1999-08-30
Abstract: The present invention solves the aforementioned inefficiencies by providing an encryption or cipher method that uses the same pseudorandom function twice rather than different pseudorandom functions. Additionally, the present invention uses hashing functions that are highly efficient. The hashing functions of the present invention are square hashing functions that square a sum of a key and a data string rather than using a multiplication. As a result the hashing operation only requires   operations rather than the w2 operations required by the inefficient hashing functions used in the prior art.. Additionally, the present invention replaces the exclusive ORed operations of the prior art with modular "n" summing operations.
Patent CA-2282170-A1 (CA)
Inventor: YOSHIMURA NORIO
IPC: G08G1/052
Filed: 1999-09-14
Abstract: An image processing section receives the image data generated by a camera and representing images of a vehicle running on a road. The image processing section acquires discrete speed data from the image data at regular time intervals. The discrete speed data is stored into a storage device. The image processing section performs least square approximation on the speed data stored in the storage device and the speed data acquired at present, thereby obtaining a continuous speed characteristic the object exhibits unit it stops. Further, the image processing section performs a differential operation on the continuous speed characteristic obtained, obtaining a continuous speed-change characteristic. A determining section determines whether the vehicle has stopped normally or abruptly. The continuous speed characteristic and the continuous speed-change characteristic can be obtained with high accuracy. As a result, it can be determined, with high accuracy, whether the vehicle has stopped normally or abruptly.

Patent CA-2285716-A1 (CA)
Inventor: SMAHA GREGORY B
Filed: 1999-10-08
Abstract: A new approach to the traditional method of selling real estate.     Commission-based sales are completely replaced with fixed periodic time based payments by the seller to a commission free agent. The real estate sales system is thus converted from a commission domain to a time rate domain. Time based payments - for example weekly -replace traditional payment of a one time lump sum commission at closing. Cash stipends for firms and agents are steady and dependable and the sellers and buyers all benefit by a much shorter time on market.

Patent CA-2294672-A1 (CA)
Title: Apparatus for assembling motor vehicle body
Inventor: SEMMYO TOSHIO
IPC: B23P21/00
Filed: 2000-01-10
Abstract: In a motor vehicle body assembly line, there is disposed, on a side of an assembly station, a movable base so as to be laterally movable. On this movable base, there are mounted a setting jig for setting a side panel and welding robots. The side panel held on the setting jig is welded to the vehicle body constituting members such as a floor panel, a roof panel, or the like which are fed into the assembly station. It is arranged to enable to set the side panel onto the setting jig from an upper side or a lateral side to thereby eliminate the necessity of securing a space for moving the side panel feeding apparatus on the side of the assembly station. For that purpose, on the movable frame there is provided a rotary frame which is rotatable about an axis of rotation which is elongated in the longitudinal direction of the assembly line. The setting jig is detachably mounted on the rotary frame and welding robots are mounted thereon so as to be movable in the longitudinal direction. In a state in which the setting jig is rotated to an upward posture or an outward posture by the rotation of the rotary frame, the side panel is set thereon. The setting jig is then turned to an inward posture to assemble the floor panel and the roof panel. A cable supporting frame for supporting the cables or the like for the welding robots are mounted on the rotary frame in a manner to project to the side opposite to the setting jig. The cables are thus prevented from getting entangled with each other as a result of rotation of the rotary fame. The cable supporting frame also functions as a balancing element to keep the rotary frame well balanced.

Abstract: L'invention porte sur un organe d'entrée d'ordinateur, tel qu'une souris et son mode de fonctionnement. Tout d'abord, la position du curseur (15) sur l'écran (11) est détectée à différents moments. Puis à l'aide de ces positions, on calcule la trajectoire du curseur (15) et sa vitesse de déplacement. Les objets affichés se présentant sur la trajectoire du curseur ou à proximité, tels que des boutons (16, 17) sont identifiés et désignés comme cibles potentielles. Les variations de la vitesse de déplacement du curseur sont également calculées. Cette information sert constater que l'utilisateur ralentit à l'approche d'un objet particulier présenté sur l'écran. Si certains critères de décélération sont satisfaits, la cible dont l'utilisateur approche est désignée comme étant la cible visée et le curseur (15) se translate alors doucement vers elle. Lorsque la flèche a atteint l'objet présenté visé, la flèche y est maintenue et les petits mouvements de la souris ne sont pas pris en compte, ce qui permet à l'utilisateur de maintenir le curseur sur la cible visée indépendamment des petits mouvements de la souris faits par inadvertance. Le maintien en place est abandonné dès que les mouvements ou accélérations de la souris dépassent certains seuils.
