Patent CA-2193379-C (CA)
Inventor: KANERVA MIKKO
IPC: H04L47/27
Filed: 1996-05-08
Granted: 2007-09-25
Abstract: The invention relates to a digital data transmission system with a non-transparent circuit-switched data connection (V.110) between a transmitting (A) and a receiving party (B), whose nominal data transmission rate may vary during a call. The data connection uses a sliding-window data flow control protocol involving transmission of data frames in a preset order, checking the order of received data frames based on this order information, acknowledgement of property received data frames and retransmission of incorrect or missing data frames. The transmissing party (A) may temporarily group the data frames, whereby the resulting "wrong" order of frames inside the group or between groups may cause unnecessary retransmissions. In the invention this is eliminated so that the receiving party (B), upon detection of a missing data frame, delays the transmission of a retransmission request for a period of time that will ensure that the missing frame has not been sent later.

Abstract: An apparatus for determining both the axial and angular positions of a defect in a tube wall. The apparatus includes a probe head positioned at the end of an elongated probe carrier having an imbedded orientation indicator. In the preferred embodiment, an encoder for measures the angular orientation of the probe head when facing the defect relative to the angular orientation of the carrier and a photodetector and reflective strip measure the angular orientation of the carrier relative to a known orientation. A data processor uses this data to calculate the angular orientation of the probe head and the location of the tube defect.

Abstract: On a mis au point un système de fluides à base d'huiles, en utilisant des particules de sel ayant une certaine répartition granulométrique, une émulsion d'huile ou d'eau dans l'huile, un agent de suspension pour suspendre les particules de sel dans l'huile, ainsi qu'un agent régulateur de filtration. Il est important que les particules de sel soient réparties dans une large plage granulométrique, pour empêcher efficacement la filtration ou les pertes de fluides dans la formation géologique. Etant donné que les particules du gâteau de filtre n'envahissent pas le puits de forage, aucune pointe de pression élevée ne se produit pendant le retrait du gâteau de filtre. Cette pointe de pression élevée, lorsqu'elle se produit, indique la présence d'un dommage à la formation géologique et à la surface du puits de forage, dommage qui, de façon générale, réduit la perméabilité globale de la formation géologique. Les propriétés rhéologiques du fluide utilisé sont telles que celui-çi peut servir dans un grand nombre d'applications où il est souhaitable de protéger la perméabilité d'origine de la formation géologique. Ces applications sont notamment le forage, la fracturation et la régulation des pertes de fluide pendant les opérations d'achèvement, telles que le gravillonnage ou le reconditionnement du puits de forage.

Abstract: A key control system comprises the generation of a first set of predetermined keys K pred which are then used as master keys for a plurality of respective postage meters. The keys are then related to a respective meter in accordance with a map or algorithm. The predetermined master key K pred is encrypted with the date to yield a date dependent key K dd related to the respective meter. The date dependent key is encrypted with a unique identifier or the respective meter to yield a unique key K final that is by the respective meter to generate digital tokens. The Data Center encrypts the date with each predetermined key K pred to yield a table of dependent keys K dd's. The table of K dd's are distributed to verification sites. The verification site reads a meter's identification from a mailpiece being verified to obtain the dependent key K dd of the meter. The verification site encrypts the dependent key K dd with the unique identifier to obtain the unique meter key which is used to verify tokens generated by the meter. In the preferred embodiment, the master key K pred, the date dependent key K dd, and the unique key K final, in the meter are stored in the meter. In an alternate embodiment, the master key K pred is encrypted with a unique meter identifier to obtain the unique key K final which is stored in the meter. The meter then generates its date dependent key K dd, which is used to generate digital tokens.

Abstract: A wood type golf club head includes a body having a face for impacting a golf ball, a top, a bottom, a toe end and a heel end. A sole plate made of high density material is attached to and substantially covers the bottom of the body. An insert made of low density material is disposed in an opening in a center section of the sole plate and extends into a cavity formed in the bottom of the body. By utilizing high density material for the sole plate in combination with low density material for the insert, a significant amount of weight is removed from the center of the club head which maximizes the perimeter weighting of the club head while increasing the moments of inertia of the club head. Preferably, the sole plate is made of a suitable metal such as brass, copper, bronze or nickel, and the insert is made of a suitable plastic.

Abstract: A communications network is used to couple weld controllers and different operator interface units together, regardless of their data structures.  An arbitration system provides a means for one operator interface unit to communicate to a selected weld controller at a given period of time. The operator interface units have one of three modes of operation. These include database master, primary master, and secondary master. During setup of the communications network, the master devices are assigned a physical address that defines the its type and priority within the network.  The database master is the only device which can automatically download data to a weld controller. It has the highest priority as a network arbiter. The primary master will act as the network abitrator in the absence of a database master. A secondary master must listen for an access grant from the current network arbiter, before initiating a message packet on the network. When no database or primary device exists on a network, the secondary device with the highest priority, as defined by its address during startup, assumes the role of network arbitrator.

Un champ magnétique statique est appliqué à un objet ayant des propriétés conductrices. Une impulsion ultrasonore est propagée à l'intérieur de l'objet, et un signal électrique est détecté, ce dernier étant lié à l'interaction entre le déplacement local associé à l'impulsion ultrasonore dans l'objet conducteur, et le champ magnétique. Dans un mode de réalisation, et de façon équivalente, une impulsion électrique est propagée à l'intérieur de l'objet, et un signal ultrasonore est détecté, ce dernier étant lié à l'interaction entre l'impulsion électrique produite dans l'objet conducteur et le champ magnétique. Les signaux acoustiques ou les signaux électriques obtenus sont traités afin de produire une image de l'objet. Les signaux obtenus dépendent aussi bien des propriétés conductrices que des propriétés acoustiques locales.

Abstract: A Short Message Service (SMS) communication network is interfaced with an Intelligent Network. In response to an indication from a mobile subscriber (20a) to transmit unstructured data towards a particular B-number, a serving mobile switching center/visitor location register (MSC/VLR) (30a) determines whether the calling party subscriber or called party subscriber is associated with an IN service.  In response to an affirmative determination, instead of transmitting the received unstructured data directly to a Short Message Service-Center (SMS-C), the serving MSC/VLR  (30a) routes an Integrated Service Digital Network User Part (ISUP) signal encapsulating the unstructured data to the associated Intelligent Network. An associated Service Switching Point (SSP) and Service Control Point (SCP) then provide the desired IN service to the received unstructured data.
