Patent CA-2202696-A1 (CA)
Inventor: ALSHAWI HIYAN
IPC: G06F17/28
Filed: 1997-04-15
Abstract: Methods and systems for language translation are disclosed.  The translator is based on finite state machines that can convert a pair of input symbol sequences to a pair of output symbol sequences.  The translator includes a lexicon associating a finite state machine with a pair of head words with corresponding meanings in the source and target languages.  The state machine for a source language head word w and a target language head word v.reads the dependent words of w to its left and right in a source sentence and proposes corresponding dependents to the left and right of v in a target language sentence being constructed, taking account of the required word order for the target language.  The state machines are used by a transduction search engine to generate a plurality of candidate translations via a recursive process wherein, a source language head word is first translated as described above, and then the heads of each of the dependent phrases are similarly translated, and then their dependents and so on.  Only the state machines corresponding to the words in the source language string are activated and used by the search engine.  The translator also includes a parameter table that provides costs for actions taken by each finite state machine in converting between the source language and the target language. The costs for machine transitions are indicative of the likelihood of co-occurence of pairs of words in the source language, and between corresponding pairs of words in the target language. The transduction search engine provides a total cost, using the parameter table, for each of the candidate translations.  The total cost of a translation is the sum of the cost for all actions taken by each machine involved in the translation.

Abstract: La présente invention concerne un procédé et un appareil qui assurent la détection du potentiel de corrosion de tuyaux dont les parois sont fabriquées à partir d'une matière conductrice (14) encastrée à l'intérieur d'une matière non conductrice, ladite matière conductrice (14) étant prise en sandwich entre les revêtements interne (10) et externe (12). Ce potentiel de corrosion provient du contact entre un support conducteur éloigné du tuyau et la matière conductrice (14) encastrée à l'intérieur de la paroi du tuyau. Le potentiel électrique existant entre le support éloigné et la matière conductrice du tuyau (14) est déterminé, puis la stabilité de ce potentiel est vérifiée. Si le potentiel ne varie pas au-delà d'une gamme prédéterminée de valeurs pendant une période donnée, le potentiel est estimé stable et est indicateur de contact électrique entre le support éloigné et la matière conductrice (14) du tuyau, ce qui favorise la corrosion. Une tension instable indique un manque de contact électrique.

Abstract: A frosting foil that has an adhesive strip attached to the back of the said foil. The product is used for the treatment of particular strands of hair on a persons head. This disclosure teaches a more time efficient and effective process at a lower cost than existing methods particularly by the foil being temporarily attached to the scalp and or hair below or above the strands of hair selected allowing the stylist to treat all the said hair that would be otherwise not accessible by known sandwich methods. The attaching of the foil to the scalp or hair other than the hair to be treated keeps the said hair to be treated completely accessible directly to the hair roots. Further folding of the blank space above the said adhesive strip by the stylist gives added strength and eliminates the requirement of backing material to the said foil.

Title: System for non-contact sensing and signalling using human body as signal transmission medium
Inventor: ALLPORT DAVID
IPC: H04B13/00
Filed: 1996-05-01
Abstract: A wireless system includes a transmitter (14) and a receiver (22) that are coupled through a user (10) and room ground (11). The transmitter produces low-frequency, low power signals that, through capacitive coupling, pass as displacement currents (13) into and from the body of the user. The shared room ground provides the return path for the current. The transmitter includes an inner electrode (18) and an outer electrode and a signal generator (16) that produces modulated signals, which vary the voltage between the electrodes. The inner electrode is closely coupled capacitively to the user's body such that the "quasi-electrostatic" field resulting from the electrode potential causes a displacement current to pass to the user's body. The outer electrode is oriented so that its coupling to the room ground is stronger than that of the inner electrode, such that room ground acts as a return path for the current from the receiver. The receiver similarly includes a pair of electrodes (24, 26), and also a detector/demodulator (28) that acquires and tracks the transmitted signal. One of the receiver electrodes (24) is closely coupled capacitively to the user's body such that displacement current that passes from the body passes to that electrode. The current then flows through detector circuitry to the other electrode(26), which is asymmetrically coupled capacitively to room ground, to complete the path for the current. The detector circuitry detects the current and operates in a conventional manner to recover the transmitted information therefrom. One or more receivers may be carried by other users or may be located in fixed positions around a room, and the return path can be a combination of air and earth ground. Accordingly, the user need not physically contact the receivers to pass information to them.  Alternatively, the receivers may be mounted as an array on a computer screen, with the transmitter located on the keyboard.

Title: Mobility management interworking
Inventor: RAJALA JUSSI
IPC: H04Q3/00
Filed: 1996-11-14
Abstract: The invention concerns mobility management interworking between a C-interface radio system and an overlay mobile radio network. Inthe first embodiment the radio system uses NCAS signalling and communicates with the SCP using the MMAP  protocol. The SCP then makes the conversion to traditional MAP protocol when necessary to communicate with other network entities. The SCP takes care of the interworking between these transactions. In the second embodiment the SCP  only relays the MAP operations embedded into TCAP messages transparently between the radio system RS and the overlay network element when the communication takes place between the RS and the overlay network. Thus the transaction is between the RS and the overlay network element. A Relay Protocol is needed between the RS and the SCP to carry the appropriate address information and to discriminate between the transparent MAP operations and non-transparent MMAP operations.
