Patent CA-2279784-A1 (CA)
Inventor: TRINKLEY KIM W
IPC: B23D17/06
Filed: 1999-08-09
Abstract: A metal shear includes a shearing blade which moves from a raised position to a lowered position to shear a workpiece. An actuating mechanism includes a lever pivotably mounted on the frame and a linkage connecting the lever to the shearing blade to move the latter between the raised and lowered position in response to pivoting of the lever. A return spring bears against the linkage and yieldably the urges the shearing blade into the raised position. A  pneumatic cylinder is mounted on the frame and has an output rod connected to the lever and responds to pressure to pivot the lever to thereby move the shearing blade in opposition to the spring to effect cutting of the workpiece. A control valve is operable to admit air pressure into the actuator to effect operation of the shear, and releases to exhaust air pressure from the cylinder to permit the spring to return the shearing blade to the upper position.

Title: Method and system for providing mediated access between signalling networks
Inventor: GLENN DEAN D
IPC: H04Q3/00
Filed: 1998-04-09
Abstract: A method and system are disclosed for mediating signalling protocol dialogue between an internal signalling network operational domain operated by one network operator and an external signalling network operational domain operated by another network operator. One embodiment provides a method of dividing the SS7 traffic (Message Signal Units or MSUs) arriving for Mediation, into classes such that network performance requirements can be met, wherein some message classes will receive only normal SS7 processing while others will be analyzed in detail. MSUs requiring detailed analysis must be routed to a mediation application process appropriate to that class. Another embodiment provides a method of manipulating Signalling Connection Control Part (SCCP) address parameters in the SMP in order to maintain normal SS7 message processing and routing functions while mediating individual messages.  Yet another embodiment provides a method enabling the SMP to route a received MSU on toward its intended final destination based on information encoded in the Message Transfer Part (MTP) addresses contained in the MSU.

Title: Fiber optic cable marking process and a sensor device for use therewith
Inventor: MCALPINE WARREN W
IPC: G02B6/44
Filed: 1999-12-16
Abstract: A mark sensor and methods for detecting a core mark disposed on a fiber optic cable core having a core receiving area for receiving the fiber optic cable core. The mark sensor includes emitter/receiver sensor devices that can be disposed about the core receiving area for observing a portion of the core for detecting the core mark. The mark sensor can include a sensor positioning system for moving the sensors relative to the core receiving area. The sensor positioning system is operative to move the sensors upon insertion of the cable core in the core receiving area. The sensor positioning system can include a linkage to another mark sensor for transmitting sensor motion to the other mark sensor. Alternatively, the mark sensor can include stationary sensors that sweep the core with radiation, for example, a bar code reader. Methods for using the foregoing sensors can result in the direct or offset marking of reverse oscillation of lay areas in a fiber optic cable.

IPC: B66D1/36
Filed: 2000-03-10
Abstract: A cable guide arrangement for a cable winch has a housing to be mounted relative to a cable winch such that a first end of housing faces the cable winch and a second end of the housing faces away from the cable winch. A cable guide channel penetrates the housing and has a closed circumferential wall. The cable guide channel has a longitudinal center axis extending perpendicularly to the first and second ends of the housing. The cable guide channel has open end portions at the first and second ends of the housing, respectively.

Patent CA-2304749-A1 (CA)
Title: Signal processing
Inventor: HOLLIER MICHAEL PETER
IPC: H04N7/26
Filed: 1998-10-09
Abstract: Communications equipment is tested for perceptually relevant distortions introduced by the equipment by generating indications (16, 29) of the extent to which such distortion would be perceptible to a human observer, and processing high-level application data (51, 61) received with the input stimulus and/or generated locally (52, 62) relating to the intended content of the input stimulus. This allows the perceptual relevance of different distortion types to be weighted in the final output from the perceptual layer (40) according to the nature of the signal being transmitted. The high-level information (51, 52, 61, 62) may be of a general nature, defining the type of information content in the input signal (11, 21) (e.g. music or speech) or may be highly defined, e.g. the input signal (61) accompanying a video input (21) specifying which of a limited set of objects in a virtual world is to be depicted, such that a reference copy of said image, or characteristic features of such objects can be retrieved from a store (62).  The high-level application data may be used for other purposes, e.g. to select a coding process suitable for the nature of the information content.

Patent CA-2314365-A1 (CA)
Inventor: DONATI MARCELLO
IPC: H04B17/00
Filed: 1998-11-26
Abstract: It is described a testing system of the receivers of a lose transceiver station for cellular telephone systems, for instance GSM 900 MHz, or DCS 1800 MHz, or TACS, etc., equipped with intelligent stray antenna having N sensors. The system consists of a radiofrequency scenario simulation equipment (SIM_RF), governed by a control processor (CONTR_PC), both connected to the bus of an Ethernet network, to which the device under testing (DUT) is also connected. The simulation equipment generates on N outputs (out1, out2..., outN) a complex signal consisting of N identical radiofrequency signals (RF1, RP2,.., RFN) differing among them for a phase progessive value. These signals are withdrawn by a same number of coaxial cables and conveyed towards the N antenna input connectors (in1, in2,..., inN) of the radiofrequency signals of the receiver to be tested. The N test signals are obtained through local generation of as many groups of N digital isofrequential carriers as are required to simulate the directions of a useful signal with an arbitrary number of echoes of the same, and the directions of an arbitrary number of isofrequential interferent carriers, and not, with their relevant echoes. The N carriers of each group are then modulated with appropriate modulation and digitally multiplied by a same number of relevant beamforming coefficients producing, within each group, an ordering according to gradually increasing phase values.
