Patent CA-2473745-A1 (CA)
Title: Electrosurgery with improved control apparatus and method
Inventor: HILAL SAID S
IPC: A61B18/22
Filed: 2002-10-24
Abstract: An electrosurgical system includes an electrosurgical generator (32) providing power through an electrode (76), and a laser (25) providing laser energy through an optical fiber. The electrode optical fiber and a source of environmental gas can all be included in a handpiece (36), catheter or other delivery device. In operation, the environmental gas can be released into the vicinity of an operative site and the laser activated to energize atoms along a pathway. Electrosurgical power can then be applied to ionize the items of the atoms of the pathway and create a path of least resistance for an electrosurgical arc. A reduction in the laser power required can be achieved by matching the photon frequency of the lawer with the excitation frequency of the environmental gas. In a laparoscopic procedure, the insufflation gas may be used as the environmental gas.

Title: Gps receiver with recalibration and methods for recalibrating and reconfiguring a gps receiver
Inventor: VARNER HOWARD GEORGE JR
IPC: H04B7/185
Filed: 2004-07-15
Abstract: A method of recalibrating a Global Positioning System (GPS) receiver includes applying a first control signal to an oscillator for generation of an oscillator signal having an initial frequency and determining if an indicator of correct oscillator output frequency is present at the initial frequency. If an indicator of correct oscillator output frequency is not present, then iterative steps are followed until an indicator of correct oscillator output frequency is found. The iterative steps include: applying a new adjusted control signal to the oscillator for generation of a new frequency; determining whether an indicator of correct oscillator frequency is present; and if an indicator of correct oscillator output frequency is present with the oscillator having the new frequency, storing said adjusted control signal. If an indicator of correct oscillator frequency is present with the oscillator output signal having said initial frequency, then storing said initial control signal.

Abstract: Dans le cadre d'une analyse de données visant à déterminer un modèle de corrélation entre l'état d'un organisme vivant et des doses d'expression de gènes multiples et/ou une quantité de substance intracellulaire, on sélectionne une variable d'explication contenue dans une masse de données. L'état de l'organisme vivant ou un changement survenu dans cet organisme en termes de probabilité avec le passage du temps est considéré comme une variable cible alors que les gènes multiples et/ou la quantité de substance intracellulaire sont considérées comme des variables explicatives. On procède ensuite à la vérification croisée du modèle de corrélation contenant la variable cible et la variable explicative ainsi sélectionnées et l'on évalue les résultats. On répète les opérations de sélection de la variable explicative, de vérification croisée et d'évaluation des résultats jusqu'à ce que les résultats de la vérification croisée ne s'améliorent plus et l'on détermine alors un modèle par la méthode des moindres carrés partiels. Avec cette invention, on dispose d'une méthode efficace de traitement de données sur l'expression génique multivariable.

Title: Seed/soil management categories: definitions, characteristics chosen and color-coded visual representations used for seed selection and management in cropping situations
Inventor: BURNS BRUCE C
IPC: G06F19/00
Filed: 2004-10-28
Abstract: A process of recommending crop varieties based on management categories. The management categories are determined by utilizing indices, which measure the economic implication of physical and chemical properties of a specific soil type in a region. The management categories may then be indicated graphically by indicia overlaying digitized soil maps, each of the indicia grouping soil types within a management category.  Each crop variety is characterized by how the crop variety performs in each of the management categories. Each of the crop varieties may then be assigned an indicium of the management category for which it is adapted.

Title: Heat exchanger for industrial installations
Inventor: PODHORSKY MIROSLAV
IPC: F28F1/12
Filed: 2004-12-21
Abstract: The invention concerns a heat exchanger for industrial installations, in particular for power plants, with at least one distributor for a fluid medium and at least one heat exchanger element attached to the distributor. The heat exchanger is composed of a sandwich-like configuration of distributors and heat exchanger elements consisting of metal sponges. The distributors are constructed as pipes or at least as semi-pipes connected with each other. Adjacent pipes or semi-pipes are connected with each other through the metal sponge. The sandwich profile of the invention may easily be manufactured in the required dimensions for industrial installations. Herein, particularly the low weight of such a heat exchanger module and the connection between shell and metal sponge, which may simply be made by means of soldering or welding, proves to be particularly advantageous. The metal foam may also be cast onto the shells.  The metal sponge should preferably consist of open-pored metal foam and in particular aluminum foam.

Abstract: Using an M:N variable matrix, M audio input signals, each associated with a direction, are translated to N audio output signals, each associated with a direction, wherein N is larger than M, M is two or more and N is a positive integer equal to three or more. The variable matrix is controlled in response to measures of: (1) the relative levels of the input signals, and (2) the cross-correlation of the input signals so that a soundfield generated by the output signals has a compact sound image in the nominal ongoing primary direction of the input signals when the input signals are highly correlated, the image spreading from compact to broad as the correlation decreases and progressively splitting into multiple compact sound images, each in a direction associated with an input signal, as the correlation continues to decrease to highly uncorrelated.

Title: Method for channel quality prediction for wireless communication systems
Inventor: PIETRASKI PHILIP J
IPC: H04B1/707
Filed: 2003-10-31
Abstract: A method of improved performance through channel quality prediction for communications systems employing link adaption techniques includes a receiver which makes selective measurements (210) on downlink transmissions, and then stores one or more of the measurements or a channel quality indicator derived therefrom (212). The receiver then retrieves one or more of the past measurements (or the past channel quality estimates themselves), and combines it with current measurements (or the current channel quality estimate), to predict what the channel quality will be at some future time and derive a predictive channel quality indicator (CQI). This predictive CQI, derived from both current channel measurements and at least one past channel measurement, is then sent to the transmitter for use in updating transmission parameters (220).

Abstract: A device for delivering a drug by inhalation is disclosed. The device includ es a body defining an interior flow-through chamber having upstream and downstream chamber openings, and a drug supply unit contained within the chamber for producing, upon actuation, a heated drug vapor in a condensation region of the chamber. Gas drawn through the chamber region at a selected ga s- flow rate is effective to form drug condensation particles from the drug vap or having a selected MMAD between 0.02 and 0.1 MMAD or between 1 and 3.5 gm. A gas-flow control valve disposed upstream of the unit functions to limit gas- flow rate through the condensation region to the selected gas-flow rate. An actuation switch in the device activates the drug-supply unit, such that the drug-supply unit can be controlled to produce vapor when the gas-flow rate through the chamber is at the selected flow rate.
