Inventor: HANNIKAINEN MARKO
IPC: G06Q50/00
Filed: 2001-09-28
Abstract: Methods and arrangements are provided for handling, within a communications system comprising a distributed domain (301) and a central domain (303), electronic records that contain predictions of the outcome of a certain incident. Within the distributed domain (301) there is generated (304), before the outcome of the incident is known, a multitude of electronic records that contain predictions of the outcome of the incident. The electronic records are conveyed (305) from the distributed domain (301) to the central domain (303). After the outcome of the incident is known, the central domain (303) finds out (306) which of the electronic records, if any, contain correct predictions of the outcome of the incident. Each of the electronic records is furnished (304, 401, 502, 902, 1202, 1911), within the distributed domain (301), with a cryptographically protected proof of a certain moment of time associated with the generation of the electronic record. The central domain (303) accepts (306, 1430, 2011) only those of the electronic records conveyed thereto as valid for which the cryptographically protected proof of a certain moment of time associated with the generation of the electronic record shows that said certain moment of time was not later in time than a certain time limit.

Title: Large round baler
Inventor: VIAUD JEAN
IPC: A01F15/07
Filed: 2003-05-20
Abstract: In known large round balers, a rotating side wall is provided that can be pivoted away from a baling chamber either in a straight line or about a pivot axis, so that the pressure on the end faces of the cylindrical bale is reduced during the unloading process. A large round baler is proposed in which a support structure provided with rolls for supporting one or more flexible bale-forming elements, which can be pivoted about a pivot axle that penetrates the side walls of the baling chamber. At least one side wall is provided with a cam having an inclined surface which is ramped outwardly from the side wall from top to bottom. The support structure is provided with a cam follower that can slide on the surface cam so as to move from bottom to top when the support structure is raised to effect a discharge of a formed bale. The cam is maintained in engagement with the follower, which travels in a vertical plane, due to outward deflection of the side wall, which results in a decrease of the force applied by the side wall on the bale and the frictional force resisting movement of the bale relative to the wall so as to aid in the discharge of the formed bale from the baling chamber.

Title: Drillhole blasting
Inventor: SKAGGS ROGER DEAN
IPC: E21C37/16
Filed: 2001-11-19
Abstract: A blasting arrangement (10) includes drillholes (30) in a rock mass (20).  Blind ends (32) are drilled to a desired level and, if necessary, are adjusted as shown at (62) to said level. Each hole (30) is plugged by means of a plug (42), which is protected by non flammable buffer material (44), at a level (40) spaced from the end (32). Explosive (50) is charged above the level (40) and the hole is tamped, shown at (60). The holes are detonated desirably by detonators (52), forcing the plugs (42) downwardly and compressing air in chambers (34) above the ends (32). The weakest part of each hole, around the end (32), is split causing a three dimensional zone of weakness at the level of the ends (32). Air forced into the zone of weakness causes a fracture zone (70) at that level, inhibiting propagation of blasting shock waves and protecting the material underneath the level of the ends (32).

Title: Technique for providing information assistance with restrictions
Inventor: BAKER NATHAN BRYANT
IPC: G06Q30/02
Filed: 2003-05-28
Abstract: A system and method for providing an information assistance service. The method includes receiving via a carrier network external to the system a communication from a user desiring an information assistance service, determining based on one or more criteria whether the information assistance service should be denied, and if it is determined that the information assistance service should be denied, generating a response to the user concerning the service denial. The criteria may include whether the caller has bad debts or has satisfied bad debts, whether there is a history of chronic bill disputes or frequent requests for service credits, whether there has been abuse of service operators, whether the user's telephone number can be identified, how much time has elapsed since a restriction on providing information assistance has been imposed, and whether ownership of a restricted telephone number has changed. In accordance with an aspect of the invention, the method includes building an automatic number identification (ANI) restriction table to keep track of calling numbers and restrictions associated with those numbers and based on the criteria. The decision to restrict service is then based on searching the ANI restriction table for the calling number. If it is determined that the information assistance service should not be denied, a database may be searched for a telephone number associated with the caller's request.

Patent CA-2446291-A1 (CA)
Inventor: RIGUIDEL MICHEL
IPC: G06F21/16
Filed: 2002-04-23
Abstract: The invention relates to a product/program and method that can be used to insert into a software program watermarks in source code, particularly Java, which respect the semantics of the program and which are very difficult to detect. Said invention can be used to: calculate a secret semantic signature of a computer software or hardware program from among an infinite number of possible secret semantic signatures; mark a computer software or hardware program by inserting a visible or invisible mark by means of watermarking that can be used to find an authenticator of the original program; find the mark and extract said authenticator using the secret semantic signature of the watermarked computer software or hardware. The secret semantic signature of the computer software or hardware program to be protected is characteristic of the semantics of said program. The visible or invisible mark, which is inserted by watermarking from an original software or hardware computer program and which can be used to find an authenticator, can only be identified by finding the secret semantic signature of the watermarked program, which requires the secret to be known (or a computing power that goes beyond the possibilities of computer hardware). The mark can withstand tracking and scrubbing methods without affecting the performance of the program to be protected.

Title: Method of clinching top and bottom ends of z-axis fibers into the respective top and bottom surfaces of a composite laminate
Inventor: MOYERS STEPHEN G
IPC: B29C70/08
Filed: 2002-08-02
Abstract: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure (33). The upper and lower skins (51a, 51b) and the core (22) are pulled automatically through tooling (23) where the skin material is wetted-out with resin and the entire composite laminate (33) is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine (24) that deposits "groupings of fiber filaments" at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that a extension of each "grouping of fiber filaments" remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station (39). Next the preformed composite laminate travels into a pultrusion die (26) where the extended "groupings of fiber filaments"  are all bent over above the top skin and below the bottom skin producing a superior clinched Z-axis fiber reinforcement as the composite laminate continues to be pulled, catalyzed, and cured at the back section of the pultrusion die. The composite laminate continues to be pulled by grippers that then feed it into a gantry CNC machine (36, 37) that is synchronous with the pull speed of the grippers (34, 35) and where computerized machining, drilling, and cutting operations take place. This entire method is accomplished automatically without the need for human operators.
