Patent CA-2233376-A1 (CA)
Title: Organometallic single source precursors for inorganic films coatings and powders
Inventor: ATWOOD DAVID ALLAN
IPC: C23C26/00
Filed: 1998-03-30
Abstract: The invention is directed to making inorganic materials consisting of a metal and a group 16 element in the stoichiometric ratio of 2:3 from single source precursors having the same 2:3 metal to heteroatom stoichiometric ratio.     In particular, the invention discloses a process for making aluminum oxide from single source precursors that have an aluminum to oxygen ratio of 2:3.  The precursors are organoaluminum tetrametallic compounds containing organooxy bridging groups and organo terminal groups.  As these compounds tend to be viscous liquids or oils, they can be applied to a substrate surface then pyrolyzed to eliminate the organic ligands and produce aluminum oxide in situ, without using gas phase deposition techniques.
Patent CA-2233898-A1 (CA)
Title: Steerable catheter
Inventor: WILSON JAMES EDWARD
IPC: A61B17/00
Filed: 1998-04-02
Abstract: An elongated steerable catheter for placement within a heart chamber, organ aperture or other body opening and having at least one center tube with hollow passageway for guiding a laser delivery means or other functional device to selected surfaces of a heart chamber, organ aperture or other body cavity for laser or other treatment thereon, particularly adapted for laser-assisted percutaneous transmyocardial revascularization (TMR), is disclosed herein. The steerable catheter has a handle portion at its proximal end and a controllably deflectable end portion at its distal end. The elongated center tube has a distal end, in the region where a curvature is to be formed, and a shim anchor sleeve is slidably disposed over the center tube. The shim anchor sleeve is attached to the inside wall of the outer jacket and coupled to the distal end of the center tube with a bendable shim member which extends between the distal tip of the steerable catheter and the sleeve over the center tube. Opposite the shim is a guide for a pull cable, the pull cable attached to the distal end of the steerable catheter and extending through the guide to the handle. Thus, the shim is maintained radially opposite the pull cable with the center tube in between. An outer jacket has, in a preferred embodiment, distinct sections of different stiffness or durometer. A distal, more flexible portion is coupled to a proximal, stiffer portion. The shim anchor sleeve is positioned at or near the junction of two portions of the outer jacket. Thus, the center tube moves freely through the shim anchor sleeve. Adjacent the handle, the outer jacket terminates at the catheter base. The pull cable extends past the catheter base, through a deflection housing tube, and terminates in a cable stop. Rotation of a deflection knob threadably mounted onto the deflection housing tube will cause the pull cable to be pulled backward, or the outer jacket to be pushed forward, relative to each other, thereby inducing deflection of the distal end of the steerable catheter.

IPC: G01V3/165
Filed: 1998-04-03
Abstract: A method and apparatus are provided for surveying a given region for the presence of ferromagnetic items and other sources of magnetic field disturbance on or under the ground, such as pipelines and wellheads, etc. An array of magnetic field sensors, mounted on a suitable framework, is passed over the region while the sensors emit appropriate signals, whereupon the signals are used to determine the total magnetic field and its gradients, with respect to distance, a) in the direction of movement, b) horizontally transverse to the direction of movement, and c) in the vertical direction. The total field and its gradients are interpreted to show the presence or absence of sources of magnetic field disturbance items, as well as to discriminate between various categories of such sources.

Patent CA-2260773-A1 (CA)
Title: Model-based fault detection system for electric motors
Inventor: DURAKBASA OSMAN TUGRUL
IPC: G01M99/00
Filed: 1997-06-20
Abstract: the present invention relates to a model-based fault detection system and method for monitoring and predicting maintenance requirements of electric motors. Since the method and system of the present invention is software based and utilizes data obtained from non-intrusive measurements, implementation costs are significantly less than prior art maintenance methods. The system comprises computer means coupled to sensors which provide continuous real-time information of the input voltage and current and motor speed. The system and method utilize a multivariable experimental modeling algorithm to obtain a mathematical description of the motor. The algorithm compares the modeled result with a measured result and quantifies the comparison in terms of a residual which is generated by subtracting the respective signals. A  diagnostic observer analyzes the residual and determines if the motor is fault free or operating in a manner other than fault free. Upon detection of the impending fault, the diagnostic observer evaluates the measured variables of the motor, determines the deviation from the reference value and develops a diagnosis of the likely failed or failing component. Another embodiment of the present invention is particularly useful in the manufacture of fractional horsepower electric motors and especially in the performance of quality control testing.
