Title: Computation of frequent data values
Inventor: RJAIBI WALID
IPC: G06F17/30
Filed: 2002-03-01
Abstract: A method is provided for computing frequent value statistics, such as the to p most frequent values in a data column, in a database management system using a combination  of hashing techniques and a varying and dynamic threshold value to compute the N most frequent values within a data column. A varying threshold value allows the method to ignore any dat a value that is not at least more frequent than the least frequent data value already in the list. During the column scan, a data value can enter and exit the list of most frequent values depending upo n the data value's own frequency relative to that of another data value. On completion of the colum n scan, the list created already holds the N most frequent values obviating the need for a further so rt operation. The method is suited for use in database management systems where performance and reliable statistics are valued.

Filed: 2000-06-14
Abstract: A positive plate active material for nonaqueous electrolytic secondary cells is substantially an Li-containing transition metal composite oxide having a composition expressed by a general formula: LixMySnzO2 (where M is a transition metal such as Co, Ni, Mn, Fe, or V (especially Co or Ni), 0.9 ~ x ~  1.15, 0.85 ~ y ~ 1.00, 0 ~ z ~ 0.001). The controllability of the particle size (reduction of particle size and narrowing of particle size distribution) of such a positive plate active material is excellent. The inner pressure of the cell does not increase. The nonaqueous electrolytic secondary cell includes a positive plate, a separator, a negative plate, a cell case containing the positive and negative plates and the separator, and a nonaqueous electrolyte provided in the cell case. The positive plate contains a positive plate active material for nonaqueous electrolytic secondary cells expressed by the general formula. Such a nonaqueous electrolytic secondary cell has improved charging/discharging and temperature characteristics and has high reliability and safety.
Patent CA-2381959-A1 (CA)
Inventor: CHARLES HARRY K
IPC: G21K1/06
Filed: 2000-08-16
Abstract: Cette invention concerne une nouvelle technique faisant appel à la précision de conception des circuits imprimés à la polyvalence de substrats minces et souples pour produire un nouveau type de réflecteur d'ions. Une série de minces bandes conductrices (traces) définies avec précision est gravée sur un substrat plat et souple de circuit imprimé. Ces bandes conductrices minces vont de préférence en s'écartant à l'une des extrémités du substrat et en se resserrant à l'autre extrémité de ce substrat. Le substrat souple est ensuite roulé en forme de tube qui formera le corps de réflecteur, les bandes conductrices constituant les anneaux du réflecteur d'ions. On peut facilement faire varier l'écartement entre ces traces, et donc entre les anneaux, en ajustant le motif conducteur sur la feuille de substrat pendant le processus de gravage. En jouant sur l'espacement des anneaux, on peut adapter facilement les caractéristiques du champ créé par le réflecteur en fonction des besoins de l'utilisateur.

Patent CA-2384979-A1 (CA)
Title: Outboard engine system
Inventor: IKENO TETSURO
IPC: B63H20/06
Filed: 2000-09-22
Abstract: In an outboard engine system, an inertia force a generated longitudinally by a piston 14 is countervailed by an inertia force b generated by a crankshaft 15, and inertia forces c and d subsidiarily laterally generated vibrate a body of the outboard engine system laterally about a phantom center point C of vibration. At this time, an elastomeric member 74 resiliently supporting the system body on a hull has a rigidity in a tangent direction (in the direction of L3) about the phantom center point C of vibration, which is set to be lower than a rigidity in a radial direction (in the direction of L2) about the phantom center point C of vibration. Therefore, the lateral vibration is reduced effectively due to the lower rigidity of the elastomeric member 74. Thrusts e and f generated by a propeller and acting in a longitudinal direction (in the direction of L1) are transmitted to the hull through the elastomeric member 74. However, the rigidity of the elastomeric member 74 in the longitudinal direction is set to be higher and hence, the thrusts e and f can be transmitted effectively to the hull.

Title: Measurement of current in a vehicle using battery cable as a shunt
Inventor: GOLLOMP BERNARD P
IPC: G01R31/00
Filed: 2000-10-03
Abstract: Current flowing into and out of a battery (1) installed in a vehicle (V) wit h the required cable (3) between one of the battery terminals and a reference point (8) on the vehicle is determined by measuring the voltage across the cable (3) and computing (22) the current from the digital value of the measured current. The resistance value of the cable can be known in which ca se the current is computed using Ohms low and a differential current sensor (30 ) can be used to respond to the voltage measured across the cable to accommoda te for different ranges of current. In an embodiment where the cable (3) resistance is unknown, a reference current source (125) produces a known voltage (128) that is used to set the input value to an amplifier (111) of fixed gain for the voltage measured across the cable by controlling the outp ut of a potentiometer (106) so that the amplifier output voltage can be set to match the reference current generator output voltage, thereby establishing t he voltage output of the amplifier as a measurement of the current flow in the cable.

Filed: 2000-10-19
Abstract: A data storage device for use as a portable card, magnetically encodeable card, magnetic credit card (100) or the like is shown. The data storage devi ce includes a substrate having at least one surface. A high density, magnetical ly coercive material layer (110) is disposed on or is deposited on the substrat e for storing magnetic signals. The magnetically coercive material may have an  axis of magnetization that is oriented in a predetermined direction relative  to the at least one surface of the substrate. A layer of non-magnetically material is disposed on the substrate for defining an exchange break layer. A relatively hard, abradeable protective coating is formed on said magnetic material layer and is selected to have a thickness between a maximum thickne ss which would materially attenuate magnetic signals passing between the magnet ic material layer and a transducer and a minimum thickness enabling said protective coating to be abraded by usage in an ambient natural atmosphere operating environment for removing therefrom a known quantity of the protective coating. The protective coating may comprise one, two or more layers of materials.

IPC: G06F13/38
Filed: 2000-10-19
Abstract: A network interface (12) independent of the computer system allows the user's computer system to connect (46) to a network without the recurring cost and requirement of a network adapter directly installed in the user's computer system. The present adaptation of the invention combines two standard computer interfaces into a single external unit able to automatically switch between an Ethernet (16) or USB (14) interface without the necessity of an external power source. When a connection is made between the PC's USB port and the current invention, USB-to-Ethernet conversion (32) is accomplished. When the USB  connection is removed, a direct connection may be made between the legacy Ethernet port of the user's PC and the computer network. When a new computer is procured the network controller internal to the computer system is not necessary, if a transceiver type on the computer system is supported by the invention's installed implementation.

Inventor: BROUSSEAU REJEAN JOSEPH HENRI
IPC: B09B1/00
Filed: 2000-11-24
Abstract: Acidity in water leaching from a mass of sulphide tailings is prevented by de-oxygenating the water prior to entering the mass. A cover comprising an electrolytic cell, either galvanic or impressed-current, gives rise to a cathode reaction in which the redox voltage of the water drops to 003 volts or less. The cover can be thinner, and much less expensive, than an equally-effective non-reactive cover. The electrolyte is water contained in water-retaining soil, or a depth of water, lying over the cathode. The cathode is steel mesh, or a layer of graphite, spread over the whole mass of tailings.
