Title: Rapid signal acquisition and synchronization for access transmissions
Inventor: ZEHAVI EPHRAIM
IPC: H04W84/08
Filed: 1998-11-10
Abstract: A system and method for rapidly acquiring timing of an access transmission that uses an access probe (500) that is transmitted in stages. A first stage (560) of the access probe preamble (520) is spread with a short pseudonoise (PN) code pair. A second stage (570) of the access probe preamble (520) is spread with both the short PN code pair and a long PN code. Transmitting the access probe (500) in stages (560, 570) reduces the number of hypotheses, and hence the time, required by a receiver attempting to acquire the access probe (500).

Abstract: A method end apparatus are provided for distributing water produced by the electrochemical reaction to an ion-exchange membrane in an electrochemical fuel cell. Water distribution within a fuel cell is improved to reduce membrane dryness near the oxidant stream inlet and to also reduce saturation of the oxidant stream near the oxidant stream outlet, thereby reducing electrode flooding. The method comprises periodically reversing the flow direction of an oxidant stream through a fuel cell flow field. The apparatus comprises an oxidant stream flow switching device (150) for periodically switching the flow direction of an oxidant stream through a fuel cell flow field (130). In one embodiment the apparatus further comprises a water recycler for capturing water from the oxidant exhaust stream and returning the captured water to the oxidant supply stream when the flow direction is reversed.

Patent CA-2323148-A1 (CA)
Title: Material moving system
Inventor: PETERS CRAIG I
IPC: B66C3/02
Filed: 2000-10-11
Abstract: A material moving system is disclosed for use in a plant such as a metal foundry. There is an overhead gantry for moving a main hook and auxiliary hook. The main hook carries a container such as a scrap charge bucket. The auxiliary hook carries a multi-function auxiliary tool such as a magnet with a tool hook affixed to the magnet. The scrap charge bucket carries a target member on a saddle on the outside of the bucket. The bucket also has a hold out stand that positions the target member for easy accessibility. The target member is attached to actuator cables that are attached to clam shell bottom members of the scrap charge bucket. The auxiliary tool may be used to lift and pull the target member to open the clam shell members without removing the magnet from the auxiliary hook, saving time. The hook on the magnet is positioned so that the hook does not damage the scrap metal bins or electric arc furnaces when the magnet is used for its usual purposes. The target member is shaped so that its position on the magnet is secure when it is lifted off of the saddle support; it has two plates with edges that complement the shape of the magnet, and with a center of gravity that tends to hold the target member against the magnet.

Title: Therapeutic system which can be moisture-activated
Inventor: BRACHT STEFAN
IPC: A61K31/40
Filed: 1999-03-18
Abstract: The invention relates to a therapeutic system for the temporal and controllable administering of at least one therapeutic active substance to a human or animal organism by means of diffusion through the skin or a mucous membrane. The active substance is initially available in a first state for production and storage. In this state, the active substance is chemically stable and is insufficiently permeable for the skin or a mucous membrane. The active substance is transformed into a second state at the application site when exposed to moisture. In said second state, the active substance is suited for diffusing through the skin or a mucous membrane, and is absorbed into the organism. The invention is characterized in that, in a first state, the active substance is contained as a pharmaceutically acceptable salt in the system. The salt is chemically transformed into the second state of an acid or base by exposure to water and by an active agent also contained in the system. Compared to the salt, the acid or base is absorbed into the organism through the skin or a mucous membrane in an accelerated and increased manner. Said active agent is a solid substance which reacts in an aqueous solution in an acidic or basic manner or is a mixture of a plurality of such substances. This active agent has a proportion of water of at least 5 % in the solid body structure thereof or is bonded thereto.

Abstract: A system and method for providing automatic validation of fares collected is disclosed. An automatic validating farebox (100), being adapted for mobile use, such as in the cabin of a bus, and to provide convenient access to both patrons and an operator, includes validation mechanisms (310 and 520) and circuitry (550) to accept patron payment in both coin and note. All tendered payment is automatically validated as to acceptable tender as well as its value being electronically registered. Accordingly, the operator is freed from validating payment of a fare and may simply confirm that the registered value is the proper amount for the type of fare purchased. The automatic validating farebox also includes mechanisms (560) adapted both to store accepted currency in an efficient manner as well as to present the collected currency in a manner readily acceptable for handling and counting.

Title: Utilisation efficace de polymeres superabsorbants (sap) dans la production de bandes continues non tissees selon le procede a la mousse
Inventor: ROKMAN KAY
IPC: D21F11/00
Filed: 1999-04-29
Abstract: On utilise le procédé à la mousse pour fabriquer des bandes continues non tissées à partir de cellulose ou de fibres synthétiques, l'un des composants de ces bandes continues étant un polymère superabsorbant (SAP). Pour minimiser l'absorption d'eau par le SAP, ce SAP peut être gelé (par exemple à environ -18 ·C), et/ou transporté par de l'eau très froide (par exemple à 1 ·C). Le SAP, ainsi qu'un support mousse ou liquide, est amené sous forme d'écoulement à faible débit dans un conduit transportant un écoulement à débit élevé d'une suspension dense de mousse renfermant des fibres, juste avant un élément foraminé. Un mélangeur mécanique peut être introduit dans le conduit pour mélanger le SAP à la suspension dense de mousse fibreuse. L'ajout de SAP au fluide de support se fait tout au plus dix secondes (de préférence, tout au plus cinq secondes) avant la mise en association fonctionnelle de la suspension dense de mousse fibreuse mélangée au SAP, et d'un ou de plusieurs éléments foraminés. La bande continue ainsi formée a un taux de siccité avant séchage d'au moins 20 % (habituellement entre environ 30 et 40 %).

Patent CA-2336119-A1 (CA)
Inventor: MCCREIGHT DICK W
IPC: B60G17/015
Filed: 1999-06-30
Abstract: Enhanced traction control is provided in a modified 6x2 vehicle. An air suspension assembly is tied to the antilock/traction controller. Thus, in response to a differential traction control event, pressurized air to air bags associated with the suspension assembly is regulated to transfer greater vehicle load to the drive axle (10). This provides improved traction capability. If the drive axle is already at its rated maximum vehicle load, then no additional weight is transferred. In addition, isolation valves (72) are added to the brake lines associated with the non-drive axle (12). The isolation valves also communicate directly with the antilock/traction controller so that braking to the non-drive axle is isolated from the drive axle. This eliminates brake drag on the non-drive axle during a differential traction control event.

Abstract: According to the principles of the invention, a fraud detection system receives data relating to telecommunications activity. Event generators generate events from the received data, with each event having a weight corresponding to an increased or decreased likelihood of fraud. The aggregated events for a subject (a subscriber or an account) determine a score for the subject, which is used to prioritize the subject in an investigation queue.  Human analysts are assigned to open investigations on the investigation queue according to the priority of subjects. In this manner, investigation resources can be applied more effectively to high-risk subscribers and events.
