Patent CA-2362057-A1 (CA)
Inventor: SHERMAN TOM
IPC: H04B1/7085
Filed: 2000-02-08
Abstract: In order to time track an incoming signal, a receiver demodulates a first instance of a signal to produce a first set of energy values corresponding to a set of possible data values of the signal (200, 270). The receiver also demodulates a second instance of the signal to produce a second set of energy values corresponding to the set of possible data values (208, 272). The receiver combines the first and the second sets of energy values to determine a combined set of energy values (210, 276). The receiver determines a first estimate of a most likely transmitted data value based upon the combined set of energy values (202, 278). The receiver decovers an early set of despread samples of the first instance using a symbol corresponding to the first estimate to produce a first early energy value. The receiver decovers a late set of despread samples of the first instance using the symbol corresponding to the first estimate to produce a first late energy value (214, 284).  Finally, the receiver determines a time offset of the first instance based upon the first early and the first late energy values.

Title: Composition and process for treating metal surfaces
Inventor: ENGEL CHRISTOPHER A
IPC: C09D5/08
Filed: 2000-03-03
Abstract: A metal substrate is provided with a coating that (i) provides substantial corrosion resistance, (ii) makes it possible to shape the substrate by roll forming and similar light cold forming operations without the need for any oil or wax lubricant, and (iii) has good adhesion to subsequently applied paint. This is achieved by coating the metal substrate surface with an aqueous liquid composition that contains acrylate polymer resin, wax, and hexavalent chromium and then drying this coating into place on the surface to produce the desired dry coating.

Abstract: Herein disclosed is an ultrasonic probe comprising a transducer for transducing an electric signal into and out of an ultrasonic wave, an electromagnet motor for rotating the transducer, a frame structure for rotatably supporting the electromagnet motor, a brake mechanism for allowing the electromagnet motor to be braked. The ultrasonic probe thus constructed can actuate the brake mechanism to brake the electromagnet motor to prevent the transducer from rotating when the electromagnet motor is stopped and release the brake mechanism to enable the transducer to rotate when the electromagnet motor is rotating, thereby protecting the transducer from a large shock caused by the electromagnet motor especially when the ultrasonic probe is dropped.

IPC: B02C17/18
Filed: 2000-04-07
Abstract: The method for verifying the filling level in a ball mill fed by material which is to be ground and provided with a rotationally mounted drum on two distant bearings consists in measuring the weight of the drum with the aid of bondage-gage weighing sensors (11-16) disposed underneath the bearings supporting the drum of the mill and in comparing the measured weight with a set value that is pre-established with a view to regulating the supply of material which is to be ground to said mill. According to the inventive method, the weight measured by a first weight value (FV) representing the vertical component of the effort created by the rotational driving torque of the drum is corrected before the comparison step.

IPC: A61C5/02
Filed: 2000-03-27
Abstract: A root canal is sequentially cleaned in sections from the crown to the apex by dividing it into three sections including an operative coronal portion, an operative middle portion and an apical portion. After an opening is formed into the tooth to provide access into the root canal, the opening is preferably rectified to remove obstructions so that the anatomical root canal can be fully accessed. The pulp material is then sequentially removed from the portion of the root canal above the apical portion of the root canal with a set of instruments (410). The apical portion is then cleaned with another set of instruments (470). An optional set of instruments (440) can also be used to improve the access into the apical portion such that irrigants can be delivered to the apical portion. Cleaning of the pulp material from the root canal also shapes the root canal to ease filling of the root canal with a filling material. The root canal preparation and shaping are completed while maintaining the original anatomy of the root canal. Each file has an abrading portion and terminates at a tip. The files of the set (410) of instruments used to clean the portion of the root canal above the apical portion have properties which enable the abrading portion of the file to conform to the configuration of the root canal while simultaneously moving the file in a cleaning motion.

IPC: G01N30/00
Filed: 2000-05-31
Abstract: An affinity separation method and system comprising an affinity separation media with low porosity and low non-specific binding, and a fluid containing  a target compound to be isolated which is capable of binding onto the affinity  separation media in a fluid mixing loop in a static filtration apparatus. Th e static filtration apparatus comprises an intermixing-chamber containing a filtration medium wherein a tangential flow is created for intermixing the affinity separation media and target compound in the fluid. The fluid is capable of passing through the filtration medium while the affinity separati on media are substantially incapable of passing through the filtration medium. The affinity separation media are separated from the fluid by opening the filtrate outlet so as to allow the fluid to pass through the filtration medi um of the static filtration apparatus. The filtrate can be thereby rendered substantially free of the target compound.

Abstract: In a wireless telecommunications system, data processing delays associated with digital channelization and de-channelization may be reduced through the use of a technique that involves processing data blocks in conjunction with the transformation of the data blocks by a large, Fast Fourier Transform (FFT) algorithm, and makes use of multiple transmission and reception branches. In accordance with this technique, the processing delays associated with the FFT  algorithm are minimized, but not to the detriment of other important channelizer/de-channelizer design characteristics, such as power consumption, die area and computational complexity.

Title: L-band amplifier with distributed filtering
Inventor: MINELLY JOHN D
IPC: H04B10/17
Filed: 2000-07-10
Abstract: An L-band optical amplifier has a rare earth doped gain medium including a filter distributed over a finite physical portion of the gain medium. The filter is distributed over between about 25 % to substantially the entire length of the gain medium. The distributed filter substantially eliminates out-of-band light emission (C-band ASE, 1520nm-1565nm) and thus improves the performance of L-band amplification (1565nm-1620nm). Examples of distributed filters include discrete type filters such as long period gratings, or continuous type filters such as rare earth doped, twin core fibers, non-adiabatically tapered fibers and coaxial resonant ring fibers.
