Patent CA-2024245-A1 (CA)
IPC: H04M3/428
Filed: 1990-08-29
Abstract: MULTILOCATION QUEUING FOR TELEPHONE CALLS Abstract This invention relates to methods and apparatus for queuing calls to a multilocation service provider having a plurality of automatic call distributors(ACDs). If all circuits to the ACDs are unavailable, a call is queued in one of a plurality of queues. One or more of these queues will allow call completion to any ACD of the service provider as soon as an agent of that ACD becomes available. Advantageously, the average waiting time for customers to that service provider is reduced, thereby improving service. In accordance with one feature of the system, the caller can select one of a plurality of choices of music on hold as offered by the service provider.

Title: Continuous nonshielding strip protective wrapping for buried pipe
IPC: E02D31/02
Filed: 1990-09-13
Abstract: A  continuous  strip  non-shielding  and  pressure-resistant wrapping material for protecting buried metallic pipe is disclosed. The wrapping material comprises a continuous layer of cold-flowable rubberized bitumen bonded to a substantially non-elastic porous support backing with a release film positioned on the exposed face of the bitumen to protect the bitumen prior to application.  When applied to a metallic pipe, the protective bitumen is secured to and held in place by the non-elastic support backing and thus cannot sag away from the pipe.  The porous support backing provides potential electric current paths through each pore so that cathodic protection can be effectively utilized to protect against corrosion in even the smallest holiday in the bitumen layer.
Patent CA-2028152-A1 (CA)
Inventor: RIPPINGALE JOHN B
IPC: G01V/
Filed: 1990-02-07
Abstract: In order to locate, trace, and identify hidden elongated objects, such as buried fiber optic cables, the objects are provided with elongated permanent magnet identifier devices having magnetic fields that may be detected at a distance from the objects. In one embodiment the identifier device comprises an elongated strip magnetized in the direction of its width and formed into a long-pitch helix, producing a characteristic "magnetic field signature" that enhances detection and identification of the object, as by a portable gradiometer that is moved over the surface of the earth along a line generally parallel to the length of the object. This embodiment may provide a magnetic field that diminishes as the square of the distance from the identifier device (rather than the usual cube of the distance), thereby enabling detection at substantial distances. In a second embodiment distinctive magnetic field signatures are produced by arrays of spaced permanent magnets, the fields of which add and subtract to provide resultant magnetic fields with peaks and valleys along a line generally parallel to the length of the object.

Title: Method of monitoring the operational state of a system
Inventor: LISZKA LUDWIK
IPC: G07C3/00
Filed: 1990-06-13
Abstract: Method of monitoring and/or diagnosing the operational state of a complicated, dynamic system constituted by a machine or an industrial process installation, a plurality (M) of state variables being measured at a plurality (N) of instants for the assembly of a corresponding measurement data (Xik), which are processed statistically to form at least one reference class corresponding to a specific operational state. There is used here a group of measurement data (Xik) serving as a learning group, which is adapted by linear projection to a new coordinate system with fewer coordinate axes. In a corresponding way, current measurement or calculation data are adapted to the new coordinate system, whereupon the distance between the current measurement or calculation data, on the one hand, and the measurement data corresponding to the learning group, on the other hand, is determined. If this distance exceeds a predetermined value, it is established which state variables that cause the deviation, by calculating the effect of the respective state variable on the variance along the respective coordinate axis in the new coordinate system.

Abstract: W.E. 56,088 Abstract of the Disclosure Both a system and method is provided for detecting faults in the insulating interface disposed between the shaft of a generator, and the bearings and seals that rotatably support it that generally comprises a transformer for selectively inducing an alternating electric potential into the shaft while the shaft is stationary, and a voltage meter for detecting whether the transformer-induced voltage is transmitted across the insulating interfaces.  The number of wire windings used in the transformer of the system is preferably chosen so that the ac voltage induced in the shaft has substantially the same characteristics as the ac voltage induced by dissymmetry currents when the shaft is rotated by the turbines which drive the electric generator.  The system of the invention is capable of not only detecting the existence of an insulation failure, but also its exact location so that only the defective portion of the insulation need be repaired.

Abstract: In speech recognition and speech coding, the values of at least two features of an utterance are measured during a series of time intervals to produce a series of feature vector   signals.    A   plurality   of   single-dimension prototype vector signals having only one parameter value are  stored.   At  least  two  single-dimension  prototype vector signals having parameter values representing first feature values, and at least two other single-dimension prototype   vector   signals   have   parameter   values representing  second  feature  values.   A  plurality  of compound-dimension prototype vector signals have unique identification values and comprise one first-dimension and  one  second-dimension  prototype  vector  signal.  At least  two  compound-dimension prototype  vector  signals comprise  the  same  first-dimension  prototype  vector signal.  The feature values of each feature vector signal are   compared   to   the   parameter   values   of   the compound-dimension prototype  vector  signals  to  obtain prototype match scores.  The identification values of the compound-dimension prototype vector  signals having the best  prototype  match  scores  for  the  feature  vectors signals are output as a sequence of coded representations of  an  utterance  to  be  recognized.   A  match  score, comprising  an  estimate  of  the  closeness  of  a  match between  a  speech  unit  and  the  sequence  of  coded representations of the utterance, is generated for each of a plurality of speech units.   At least one speech subunit,  of  one  or  more  best  candidate  speech units having the best match scores, is displayed.
