Title: Pinpointing interruptions in communication links
Inventor: TROMMEL ERIC SIMON
IPC: H04B17/40
Filed: 1997-10-10
Abstract: The invention relates to a method for pinpointing an interruption in a link for transmitting digital signals between a first station and a second station on the basis of the times of occurrence of signal changes on the link. In accordance with the invention, the method is characterised by generating signal changes after the link has been restored. Preferably, the time of restoration is determined on the basis of data signals received, and a detection signal is fed to the link after the determination of the time of restoration. On the basis of the difference in time of observing restoration and of receiving a detection signal, the location of the interruption is determined. For this purpose, the length of the link need not be known.

Patent CA-2266618-A1 (CA)
Title: System and device for, and method of, processing baseband signals to combat isi and non-linearities in a communication system
Inventor: HUMBLET PIERRE A
IPC: H04L25/03
Filed: 1997-09-23
Abstract: A system and device for, and method of, processing baseband signals to combat ISI and non-linearities on a communication system having a local loop. An actual alphabet is formed (471) from the signals actually transmitted on a channel (250). The alphabet may be used for symbol decoding (470), for example, and may avoid erroneous symbol predictions that could occur if an ideal or proscribed alphabet were used. Conventional phone systems have local loops with conventional line interfaces believed to have non-linearities vis-a-vis the proscribed companding algorithm. In particular, baseband signals created from the inverse quantization mechanisms inherent in conventional line interfaces have non-linear distortions. The actual alphabet therefore corresponds to the low fidelity signals actually transmitted by the line interface (250), with each symbol being an estimate of the signals actually transmitted (475). The estimate may be formed from an averaging function. An equalizer (460) may be used to combat ISI and other channel distortion. The alphabet and the equalizer may be updated with an error signal that is indicative of the accuracy of the alphabet's estimates (481).

Title: Synchronisation amelioree d'un recepteur avec un emetteur au moyen d'essais precoces/tardifs pendant la phase de synchronisation approximative
Inventor: WANG ERIC YI-PIN
IPC: H04W56/00
Filed: 1997-10-07
Abstract: Cette invention se rapporte à un procédé et à un appareil de synchronisation, qui permettent de synchroniser un récepteur, tel qu'un radiotéléphone (24) fonctionnant dans un système de communication cellulaire (10), avec un émetteur. A cet effet, un signal de synchronisation est transmis à l'intérieur d'une multitrame (MF) d'un signal de commande en direction du récepteur, lequel, après mise sous tension, détecte un train de bits numériques non différenciés et divise ces bits en une succession de parties ou de cases séparées (b). Les accumulations d'énergie à l'intérieur de chacune de ces parties sont calculées et le profil dans l'espace (M) des parties entrant dans un modèle de rafales de synchronisation est mesuré et informatisé. Le profil dans l'espace des parties adjacentes est également mesuré et informatisé. En considérant les différences entre une partie donnée et des parties précédant ou suivant cette partie donnée, une mesure de différence (D) peut être utilisée pour mieux prévoir l'occurrence d'une limite multitrame, facilitant ainsi la synchronisation, en dépit de la présence d'autres rafales haute puissance dans la transmission.

Title: Downhole jar apparatus for use in oil and gas wells
Inventor: HIPP JAMES E
IPC: E21B31/113
Filed: 1999-06-09
Abstract: A downhole jar apparatus for use in oil and gas wells provides an improved construction that features a movable piston that imparts upward blows to the tool body during use. The apparatus includes an elongated tool body having upper and lower end portions and a longitudinal flow bore for enabling fluid to pass from the upper end of the tool body to the lower end portion thereof. A pair of pistons are slideably mounted within the tool body including an upper piston having a seat and a lower piston having a seat. A ball valving member is used to seal the upper piston, that ball valving member being pumped down through a work string such as a coiled tubing unit in order to reach the seat of the upper piston. A second valving member in the form of an elongated dart is disposed in between the two pistons. A trip mechanism separates the second valving member from the lower piston when a predetermined hydrostatic pressure value is overcome. Once the second valving member and lower piston are separated, the second piston is fired upwardly striking an anvil portion of the tool body to create the upward jar or blow.

Inventor: VAN WONTERGHEM GEERT ARTHUR ED
IPC: H03H11/02
Filed: 1999-06-15
Abstract: A low-pass filter arrangement (LP) associated to clamping means (T1) for limiting unwanted transient signals to be transmitted through the filter.  Mainly the variations (dl/dt) of the current (I) flowing through the filter are eliminated.  The filter may form part of a splitter used in an ADSL system to separate low frequency POTS signals from high frequency ADSL signals simultaneously transmitted over a same copper twisted-pair transmission line (TP). The filter basically comprises the series connection of a coil (L1) and the main path of a transistor (T1) of which the gate terminal is connected to the opposite end of the coil. It has been proved that, in case of an ADSL system, a classical 7th order low-pass filter may advantageously be replaced by a 3rd order filter arrangement as of the present invention.

Title: System for raising and lowering a liner of a fluid bearing receptacle
Inventor: MCROBERT IAN
IPC: E04H4/14
Filed: 1997-12-30
Abstract: A system (10) for raising and lowering a liner (12) or a swimming pool (14) includes a plate (22) used to define a spill way (24) for providing fluid communication between an outside surface (26) of the liner (12) and an inside surface (16) of the pool (14). The liner (12) is detached from surface (16) of the pool in the region behind the plate (22) and reattached along upper edge (28) of the plate (22) using a conventional locking strip (20). Conduit (30) has a length (30') which extends along back face (32) of plate (22) below the upper edge (28). Holes (34) cut in the plate (22) provide communication with length (30'). Conduit (36) having a length (36') extends across the back face (32) near its lower edge (38) to provide air to the spill way (24). The length (36') is provided with a number of holes (40) for admitting air into the spill way (24). In order to lift the liner ( 12), air is directed through conduits (30, 30') to the outside surface (26) of liner (12). The air progressively lifts the liner up and away from the inside surface ( 16) displacing water held within the pool (14) to flow over upper edge (28) into the spill way (24) so that the water now lies beneath the outside surface (26). In this way the liner (12) is progressively raised to eventually lie above the level of the water. To return liner (12) to its lining position air is passed through conduits (30, 36) into spill way (24). As the air rises it carries water up the spill way (24) and over the upper edge (28) onto the inside surface of liner (l2) to sink the liner (12) back to its lining position.

Title: Power assisted liposuction and lipoinjection equipment
Inventor: MOZSARY PETER G
IPC: A61B17/22
Filed: 1998-03-09
Abstract: A power assisted liposuction/lipoinjection handpiece includes a handle (12) which provides power to reciprocate a cannula (10) back and forth during surgery. The cannula (10) can be connected to the handle (12) by a connector (24) that is affixed to, integrally formed with, or selectively joinable to a reciprocating member (14). Benefits in sterilization, distribution and surgical use can be realized when the cannula (10) and connector (24) are joined together, such that the surgeon merely needs to remove the cannula (10) from the package and connect it to a reciprocating member of a powered handle (12). The handle (12) may be configured such that the reciprocating member (14) is selectively detachable; thereby, allowing the handle (12) to be used for additional surgical procedures such as sawing or drilling.  A vacuum hose (26) is connected to the cannula (10) such that vacuum pressure can be exerted through the cannula (10) for aspirating severed fat tissue. Preferably, the connector (24) radially offsets the cannula (10) from the reciprocating member (14) to a position which is axially in alignment with the vacuum hose (26); thereby avoiding bend regions and enhancing suction.

Title: Laser imageable printing plate and substrate therefor
Inventor: FROMSON HOWARD A
IPC: B41C1/10
Filed: 1998-05-21
Abstract: A metal substrate is treated with a plurality of rotating brushes and a slurry of particulate material such that the treated surface is capable of absorbing incident infrared laser radiation. The substrate is itself capable of being visibly imaged by selective writing with an infrared laser. The substrate is coated with an ablatable coating which is transparent to the imaging infrared laser radiation. Selective exposure to infrared laser radiation ablates this coating in the laser exposed areas as a result of the absorption of infrared radiation by the substrate. The substrate can be anodized after rotary brush graining and still retain its ability to be imaged and ablate a coating. The coated article can be imaged in a computer-to-plate infrared laser imaging device. Depending on the specific coating and substrate selection, the imaged article can be used in a conventional lithographic printing process or in a dryographic printing process.
