Patent CA-2297954-A1 (CA)
Inventor: KELLEY TRACY E
IPC: H01M50/426
Filed: 1998-06-19
Abstract: The methods and compositions of the invention provide two solutions to reduce the reactivity of VDF-based copolymers to lithiated graphite. The two approaches can be used separately or combined. In one embodiment, the relative proportion of the VDF and the other fluorinated monomer (OFM, i.e. HFP) in the copolymer is significantly reduced below conventional formulations in order to reduce the reactivity of the copolymer. In a second approach, the reactivity of the copolymer, over a broad range of monomer VDF:OFM molar ratios, is reduced by deactivating the reactive sites on the copolymer, thereby blocking the ability to undergo undesired reaction during cell operation. These methods and compositions have heretofore not been proposed and are of primary importance in preventing large exothermic reaction which can lead to thermal runaway when conventional polymer formulations are utilized in batteries in the presence of reactive components such as lithiated graphite.

Title: Apparatus for storing, mixing, and dispensing two-component bone cement
Inventor: HAJIANPOUR MOHAMMED ALI
IPC: B01F15/00
Filed: 1998-07-24
Abstract: Apparatus for storing, mixing, and dispensing a two-component bone cement includes a first component supply section (10), a mixing section (12), and a drive base (14). One or more ampules (18) of the first (liquid) component (16), provided within the first component section (10), are broken or cut when a lever (36) is rotated. The second (powder) component (20) is provided within the mixing section (12). During the mixing process, a vacuum is applied within the mixing section (12), assisting in the delivery of the first component (16) through a filter (68) while preventing the passage of broken glass or plastic from the ampules (18). Mixing is done by a pair of paddles (98, 99) and a helical spring (106) rotating within the mixing section (12), being driven in one direction, or in alternating opposite directions of rotation, by the drive base. The resulting mixture (165) is dispensed by placing the mixing section (12), without the drive base (14) and the first component supply section (10), into a dispensing gun, which drives a shaft (182) moving a piston (102) within the mixing section (12) to dispense the mixture (165) through a dispensing tube (166) while collapsing the helical spring (106). A plug (204) within the piston (102) is pushed through the dispensing tube (166) to clear the mixture (165) remaining therein. In an alternative arrangement, mixing occurs under vacuum conditions in a bowl (392) having an internal surface (397) similarly scraped with a flexible wire (410).

Patent CA-2310432-A1 (CA)
Title: Three dimensional optical scanning
Inventor: GODIN GUY D
IPC: G01B11/24
Filed: 2000-06-01
Abstract: A method of determining the color and profile of a target surface involves scanning the target surface with an incident light beam containing a plurality of component wavelengths, forming a beam of light reflected from the target surface and synchronized with the incident beam; and splitting the reflected beam into separate sub-beams of different wavelengths. The sub-beams are directed onto a sensor array to permit their relative positions to be determined as the incident beam moves over the target surface. A portion of the reflected beam is directed onto a color sensitive photodetector to obtain data representative of the approximate color composition of the reflected beam. The color and profile of the target surface is determined from the relative positions of the sub-beams on said sensor array using the data representative of the approximate wavelength composition to resolve ambiguities in the results. The split portion of the reflected beam can also be sampled at a higher rate than the sensor array to obtain information about the appearance of the surface at a higher resolution than possible with the sensor array alone.
Patent CA-2312586-A1 (CA)
Title: Syringe pumps
Inventor: FORD ANDREW JOHN
IPC: A61M5/20
Filed: 2000-06-27
Abstract: Conventional syringe pumps have a plunger head retainer and some means for detecting occlusion or other restriction to movement of the plunger. In the present invention, the plunger head retainer has two retainer arms mounted on shafts extending parallel to the syringe axis. Each shaft carries a gear, which is engaged by common gear wheel mounted on a threaded shaft. Initially, the shaft is rotated to displaces the gear and hence the retainer arms axially forwardly, and thereafter swing the retainer arms outwardly to an open position. After the syringe has been loaded in the pump, the plunger head retainer is driven forwards until a pad coupled with a force sensor detects contact with the head. This causes the retainer arms to be swung in across the forward side of the plunger head and to be pulled rearwardly against the plunger head. The pump then reduces the force applied by the retainer arms to ensure that the force sensor can respond to force on the plunger during expulsion of liquid from the syringe.

Patent CA-2325116-A1 (CA)
Title: Data slicer with digitally-controlled reference
Inventor: JELEA FLORIN
IPC: H04L25/06
Filed: 2000-11-03
Abstract: The present disclosure discloses a method and apparatus for slicing data, or "squaring up" a signal such as the output of a wireless receiver demodulator for proper interface with conventional digital logic circuits. The method involves the receiving of an input signal, the generation of a reference level, the comparison of the input signal to the reference level, and the measurement and storage of the reference level.  The reference level is generated by applying the input signal to a filter, which has been previously set to an initial condition. The reference level is measured at a predetermined point in a receive data frame, and is maintained at the desired level throughout the remainder of the frame. After a frame has been received, the reference level is stored if the frame data output from the data slicer contained no errors. For multi-channel receivers, in which a different data slicer reference level may be optimal for each channel, a separate filter initial condition can be stored for each channel, and the reference level is set to the stored initial condition corresponding to the current channel prior to receiving data on the current channel.
Patent CA-2330926-A1 (CA)
Title: Search window delay tracking in code division multiple access communication systems
Inventor: SCHULIST MATTHIAS
IPC: H04B1/711
Filed: 1999-04-29
Abstract: The present invention provides a search window delay tracking procedure for use in a multipath search processor of a CDMA radio receiver. A channel impulse response is estimated for a received signal containing plural paths, each path having a corresponding path delay. A search window defines a delay profile that contains the plural paths of the received signal. A mean or average delay is calculated for the estimated channel impulse response (CIR), and an error is determined between the mean CIR delay and a desired delay position corresponding to the center of the CIR search window. An adjustment is made to reduce that error so that the center of the search window and the mean CIR delay are aligned. The error may be processed either linearly (in one embodiment) or non-linearly (in another embodiment) to minimize the error and to reduce an influence of noise. A non-linear filtering process includes calculating a delay spread from the mean CIR delay calculated for successive processing cycles of a window delay tracking procedure corresponding to each new input. A difference is determined between the successive delay spreads. Adjustment signal is set equal to the error signal if the difference is less than or equal to a threshold. Alternatively, the adjustment signal is set to zero if the difference is greater than the threshold. Consequently, if the delay spread in the current iteration is significantly different from the delay spread in the previous iteration, the new error sample calculated in the current iteration is considered unreliable, and no adjustment is made.
