Patent CA-2468363-A1 (CA)
Inventor: ERHART GEORGE W
IPC: G10L15/22
Filed: 2004-05-26
Abstract: A method and apparatus are disclosed for validating agreement between textual and spoken representations of words. A voice input verification process monitors a conversation between an agent and a caller to validate the textual entry of the caller's spoken responses or the agent's spoken delivery of a textual script (or both). The audio stream corresponding to the conversation between the agent and the caller is recorded and the textual information that is entered into the workstation by the agent is evaluated. Speech recognition technology is applied to the recent audio stream, to determine if the words that have been entered by the agent can be found in the recent audio stream. The grammar employed by the speech recognizer can be based, for example, on properties of the spoken words or the type of field being populated by the agent.   If there is a discrepancy between what was entered by the agent and what was recently spoken by the caller, the agent can be alerted and the error can optionally be corrected.

Abstract: L'invention concerne un procédé et une procédure permettant de laisser la peau souple, avec de petits pores et un aspect jeune. Ce procédé comprend un prétraitement topique de la peau à l'acide rétinoïque, l'application sur la peau d'un contaminant dans l'huile, et le retrait du contaminant par son explosion ou sa rupture à la lumière laser. Lors du traitement du visage, il suffit d'environ 4 minutes pour enlever le contaminant. La lumière laser elle-même ne provoque pas de lésion de la peau mais la rupture du contaminant engendre une lésion thermique dans le derme laissant l'épiderme intact. Des traitements laser intermittents répétés et des applications d'acide rétinoïque topique donnent les résultats souhaités à la peau aussi longtemps que les traitements et les applications sont poursuivis.

Title: Reverse-cycle heat pump system and device for improving cooling efficiency
Inventor: SMOLINSKY DAVID
IPC: F25B13/00
Filed: 2001-05-07
Abstract: An improved reverse-cycle heat pump system (100) is disclosed that comprises components to improve the efficiency of the system in the cooling mode.  Specifically, the invention incorporated a conduit assembly (50) for carrying refrigerant from one heat exchanger to the other heat exchanger, wherein the heat exchangers (20) are configured to function interchangeably as a condenser and evaporator, depending upon whether the system is operating in cooling mode or heating mode. The conduit assembly (50) includes a coiled section (53) of tubing disposed near the heat exchanger that functions as an evaporator (20) in cooling mode. This coiled section functions as a reservoir for collecting excess refrigerant liquid from the "evaporator" during operation of the system in the cooling mode. Consequently, in cooling mode, heat dissipation via the condenser is thereby increased since less refrigerant liquid is contained therein, resulting in improved cooling of the conditioned area or substance.

Title: A method and system to solve dynamic multi-factor models in finance
Inventor: MUCHNIK ILYA
IPC: G06F19/00
Filed: 2003-05-07
Abstract: Methods and systems for estimating time-varying factor exposures of either a n individual financial instrument or a portfolio of such instruments, through the solution of a constrained multi-criteria dynamic optimization problem, providing an estimation error function and one or more transition error functions to be minimized over a period of time. The factor exposures relay the influence of the factors on the return of the instrument or portfolio. T he estimation error function provides the estimation error at each time interva l between the return of the asset collection and a sum of products of each factor exposure and its respective factor. Each transition error function provides a transition error of each factor exposure between time intervals. In one embodiment, the constraints can include a budget constraint and non- negativity bounds applying to some or all of the factor exposures. In other embodiments, the method and system can be applied to estimating any time- varying weight that is used in a model, to relay the influence of one or mor e independent variables on a dependant financial or economic variable, through the solution of a constrained multi-criteria dynamic problem, minimizing estimation error and transition error terms. In other embodiments, the solution of a multi-criteria dynamic problem can be used as part of a method and system to determine structural breakpoints for each factor, an also as part of a method and system for determining optimal parameters to weight the transition error functions and selecting the factors included in the model.< /SDOAB>

Title: Method of making a medical device having a thin wall tubular membrane over a structural frame
Inventor: MAJERCAK DAVID CHRISTOPHER
IPC: A61F2/82
Filed: 2003-05-06
Abstract: The present invention relates to a medical device and method for making the medical device. In particular, the present invention relates to membrane covered structural frame, and to a method of forming a tubular membrane on a structural frame. In one aspect, a polymeric tube is provided having a first diameter and a first tube wall thickness. A radially expandable and contractible structural frame is radially contracted, and inserted into at least a portion of the structural frame. The radially contracted structural frame then expands to expand the polymeric tube to a second diameter, wherein the second diameter is greater than the first diameter. As the polymeric tube radially expands, the tube wall thickness becomes thinner, so that the polymeric tube becomes a thin walled tubular membrane. The polymeric tube and structural frame are then mechanically attached to each other.

Title: Methods for the identification of allo-antigens and their use for cancer therapy and transplantation
Inventor: MOLL HEIDRUN
IPC: C07K7/06
Filed: 2003-06-13
Abstract: The present invention delivers a new concept with respect to the broad definition of alto-antigens that drive graft-versus~tumor (GVT) reactions and/  or graft-versus-host disease (GVHD). The new method for the identification of allo-antigens, which has so far been an unresolved technical problem, furthermore calls for new strategies in immunotherapy. Because the analysis of HLA-binding proteins can now be done with alloantigens for which the corresponding amino~acid sequence is known, the present invention also allows the separation of alto-reactive T cells that only recognize tumor cells from those that mediate GVHD. Antigens defined with the new technology are especially useful for diagnosis and vaccination in cancer and transplantation-related diseases.

Abstract: Methods and apparatus compress data, comprising an In-phase (I) component an d a Quadrature (Q) component. The compressed data (212) may be saved into a memory or may be transmitted to a remote location for subsequent processing or storage. Statistical characteristics (505, 507) of the data are utilized to convert the data into a form that requires a reduced number of bits in accordance with the statistical characteristics. The data may be further compressed by transforming the data, as with a discrete cosine transform (203), and by modifying the transformed data in accordance with a quantizati on conversion table (205) that is selected using a data type associated with th e data. Additionally, a degree of redundancy may be removed from the processed data with an encoder (207). Subsequent processing (1200) of the compressed data may decompress the compressed data in order to approximate the original data by reversing the process for compressing the data with corresponding inverse operations.
