Patent CA-2291204-A1 (CA)
Title: Fingerprint identification device equipped with a touch sensor for detecting a human finger
Inventor: NAGAYAMA KEIICHI
IPC: G07C9/00
Filed: 1999-11-29
Abstract: A fingerprint identification device judges that the input fingerprint is identical to the fingerprint in the database only when a the touch sensor detects the human finger and a the fingerprint processing unit detects that the input fingerprint is identical to a fingerprint in the database. The touch sensor includes an oscillator that outputs a high frequency signal. An electrode unit applies the high frequency signal to the human finger. A detector unit detects a variation of impedance values varied by the human finger contracting the electrode unit and outputs an output signal based on the variation of impedance values. A discriminator unit determines whether the human finger is in contact with the electrode unit by comparing the output signal from the detector unit with a predetermined reference value.

Patent CA-2291531-A1 (CA)
Inventor: JONES KEVAN PETER
IPC: H01S3/067
Filed: 1999-12-03
Abstract: A construction of gain tilt exhibiting optical amplifier that incorporates a gain flattening filter also includes a neutral density filter the value of whose attenuation is adjustable after assembly of the components of the amplifier. This neutral density filter is constructed by the performance of a succession of localised re-fusion operations at a localised region of an optical fibre. By this means the attenuation is increased to a desired value that provides the amplifier with optimised gain flattening at some predetermined value of amplifier external gain.

Inventor: SURESH MITTA
IPC: A61F2/958
Filed: 1999-03-05
Abstract: A catheter and method of use as an aortic balloon catheter having an integral expandable/collapsible lumen. The catheter comprises a main catheter body having a plurality of lumens extending therethrough, and further includes an expandable/collapsible lumen disposed thereabout and carried by the main catheter body. The expandable/collapsible lumen has a relatively large diameter when inflated with respect o the main catheter body, and is self inflating by fluid pressure when the fluid flows therethrough. The large inflatable/collapsible lumen is attached ax its distal end to the main catheter body and thus is carried therewith into a body vessel, and thus is also supported by the catheter body to avoid kinking. The catheter of the present invention is ideally suited for insertion into smaller access arteries for placement into larger arteries, such as an aortic balloon catheter which carp be inserted into a smaller femoral artery and advanced into the ascending aorta to provide arterial return of oxygenated blood into the ascending aorta. The catheter further has an adjustable length. The present invention also achieves technical advantages as a catheter for insertion into any body vessel having a limited diameter and which is susceptible to trauma, such as a urethra.

Patent CA-2319524-A1 (CA)
Title: Grain quality monitor
Inventor: MAYES DAVID M
IPC: G01N21/35
Filed: 1998-02-18
Abstract: Percentage concentrations of constituents of a sample of cereal grain or other agricultural product in a flowing stream are determined while harvesting or processing using a short wave near infrared analyzer. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths.      The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the same portion of the product being analyzed. Percentage constituents of the composite substance may then be compared with known percentage constituents to determine the constituents.   The analyzer is optically stabilized and is therefore suitable for attaching to the agricultural combine to perform real time measurements in the field.

Title: A differential line driver
Inventor: WIKNER JACOB
IPC: H03F1/56
Filed: 1999-03-02
Abstract: A fully differential line driver, especially for twisted copper pairs. It comprises two current amplifiers (A p, A n), made in standard CMOS technique, each having an input (I inp, I inn) and an output (I op, I  on), which latter are connected via terminal resistors (R t) to a voltage source, which may be set to a larger voltage than that used for driving the CMOS amplifiers. With this invention, a low output impedance can be combined with a large swing. Further, feedback is not necessary, avoiding problems like potential instability. A preferred embodiment also has a very low-impedance input, making it appropriate for connecting to a DAC, thus reducing distortion of its output signal. The invention is suitable for very-high-speed-digital-subscriber-line modems.

Abstract: A production and finishing system, particularly a printing and finishing system, for electronic management and control of a wide range of finishing processes characterized by input from multiple production operations and equipment that, depending upon the job, may be variably applied to work pieces that themselves are highly variable between different jobs. Particular emphasis is demonstrated in relation to printing and finishing operations for printed documents. The principles of the present invention, however, apply to such production and finishing systems as, without limitation, textile production (which may include printing, cutting, sewing, and finishing), packaging operations for various consumer and industrial products, and printed wiring board production, etc. The present invention is particularly applicable to many operations where processes for production of work pieces are managed separately from processes for finishing and packaging of such work pieces.
