Patent CA-2302124-A1 (CA)
Inventor: ANDERSON CARL
IPC: H04M1/00
Filed: 2000-03-24
Abstract: A line driver for connection to a transmission line having a characteristic impedance. The line driver can be arranged in a voltage-mode or a current-mode configuration.      In the voltage-mode configuration, the line driver comprises an amplifier, a transformer, a reference resistor and a feedback circuit. The first winding of the transformer has a first end connected to the output of the amplifier and the second winding is connectable to the transmission line. The reference resistor has an end connected to the second end of the first winding at a junction point and the feedback circuit is connected to the input and output of the amplifier and also to the junction point. The reference resistor has a resistance equal to ~ times the characteristic impedance of the transmission line. The feedback circuit is arranged to produce a voltage at the output of the amplifier substantially equal to -(K-1) times the voltage at the junction point, for a predetermined value of K. This results in a synthesized output impedance equal to the characteristic impedance of the transmission line, while losses in the reference resistor are reduced. At the same time, the gain is easily set by the specifying the resistance of a source resistor placed at the input to the amplifier.

Title: Arrangement for the control of the forward propulsion speed of a harvesting machine with fuzzy logic
Inventor: WEBER KONRAD ANDREAS
IPC: A01D41/12
Filed: 2000-05-05
Abstract: A crop harvesting machine is equipped with a crop intake arrangement which delivers crop to a crop processing arrangement. In order to maintain a substantially constant flow of crop to the crop processing arrangement despite a variance in the amount of crop located in various locations on a field, a control circuit employing non-precise or fuzzy logic controls the forward propulsion speed of the harvesting machine and/or the speed of a conveyor used to unload a buffer or crop accumulator that is mounted upstream from the crop processing arrangement. This control is based on crop flow data obtained by a sensor that senses the rate and/or the amount of a crop taken up by the crop intake arrangement, and by a fill sensor associated with a buffer which temporarily accumulates crop at a location upstream from the crop processing arrangement.

Title: Microthermistor based fingerprint sensor
Inventor: PICARD FRANCIS
IPC: G06K9/20
Filed: 2000-06-16
Abstract: The present invention concerns a fingerprint sensor which is small; demonstrates high sensitivity, low power consumption, high data acquisition rate and is insensitive to vibration and pressure. The sensor produces a high contrast fingerprint representation and is not subject to repeated deformation which could potentially reduces its lifetime. The fingerprint sensor has a microthermistor array for converting temperature variation into an electrical signal, the array being composed of a plurality of microthermistors, each of the thermistors being adapted to output an electrical signal proportional to a temperature variation; a read-out integrated circuit operatively connected to the microthermistor array for receiving the electrical signal and converting it into an electronic output signal representative of the ridge and valley structure of a finger; and a substrate for supporting the read-out integrated circuit and the microthermistor array. The invention is based on microthermistor array. The ohmic resistance of these sensors varies strongly with temperature. The parameter directly measured in this case is the temperature-induced resistance variation of each individual microthermistor. Signals from each of the microthermistor part of the array represent the fingerprint pattern.

Patent CA-2321368-A1 (CA)
Inventor: FARRAR LEWIS W
IPC: H04L7/02
Filed: 2000-09-27
Abstract: A method of data recovery includes receiving a data stream of data bits and splitting the data stream to N identical input data streams where N is an integer greater than 1. Each of the N input data streams is delayed with respect to the preceding one by a bit time divided by N. Each of the N delayed input data streams is then sampled using a local clock to provide N samples which form an N-bit sample code per clock period. At least two successive sample codes are decoded to select one of the N delayed input data streams most aligned with the local clock. The selected data stream is thereby retimed to the local clock for synchronous processing of the data stream payload. The local system clock is held constant in the presence of multiple asynchronous data streams for improved robustness in overall system performance.

Title: Process for the purification of (±)-2-azabicyclo[2.2.1]hept-5-en-3-one
Inventor: DE SCHRIJVER JOHNY
IPC: C07D209/52
Filed: 1999-02-12
Abstract: The invention relates to a method for purifying (~)-2-azabicyclo[2.2.1]hept-5-en--3-one.  To date crystallisation constituted the final purification step in the production of (~)-2-azabicyclo[2.2.1]hept-5-en-3-one. It is, however, advantageous from both the economic and ecological point of view to carry out purification exclusively by means of extractive measures. The method comprises the steps of extracting an aqueous reaction solution of (~)-2-azabicyclo[2.2.1]hept-5-en-3-one with an organic solvent, separating a resulting organic phase containing the (~)-2-azabicyclo[2.2.1]hept-5-en-3-one from a resulting aqueous phase, mixing the resulting organic phase with water, and separating a final aqueous phase containing the (~)-2-azabicyclo[2.2.1]hept-5-en-3-one from a final organic phase.

Abstract: The present invention provides a method of detecting nucleotide variation within a first nucleic acid, comprising generating a set of single-stranded extension products from a first nucleic acid in the presence of modified nucleotide bases, wherein the extension products incorporate modified nucleotides and thereby limit exonuclease activity to the 3'-terminal nucleotide base, and wherein the extension products have variable lengths, hybridizing the variable length extension products to a reference nucleic acid, contacting the hybridizing nucleic acids with an enzyme which can remove and replace the 3'-terminal nucleotide of the extension products in the presence of selected labeled nucleotides, wherein extension products that terminate with a 3'-nucleotide that does not hybridize with the corresponding position on the reference nucleic acid are replaced with one or more nucleotides that hybridize with the corresponding nucleotides on the reference nucleic acid and wherein those extension products that had a non-hybridizing nucleotide at the 3'-terminus can now be distinguished from those extension products that had a hybridizing nucleotide at the 3'-terminus, and distinguishing those extension products that had a non-hybridizing nucleotide at their 3'-terminus from those extension products that had a hybridizing nucleotide at their 3'-terminus, thereby detecting nucleotide variation in the first nucleic acid. Alternatives of this method are also provided which can also detect mutations in a nucleic acid at the penultimate 3'-terminal position on the single-stranded extension products.
