Title: Systeme et procede pour gerer des ordres de negociation recus des teneurs de marche
Inventor: SWEETING MICHAEL
IPC: G06Q40/00
Filed: 2005-07-21
Abstract: Dans un mode de réalisation, l'invention concerne un procédé de gestion de la négociation. Une première proposition portant sur un instrument déterminé sur un marché déterminé est reçue d'un teneur de marché à un prix de première proposition. Une première offre pour le même instrument déterminé sur le même marché est reçue d'un deuxième teneur de marché à un premier prix d'offre, le premier prix d'offre étant supérieur ou équivalent au prix de première proposition. Comme le premier prix d'offre est supérieur ou égal au prix de première proposition, le premier prix d'offre est automatiquement augmenté à un prix supérieur à celui du prix de première proposition, de manière à ce qu'aucune transaction ne puisse s'effectuer entre la première proposition et la première offre. Dans certains modes de réalisation, ce procédé peut s'utiliser pour protéger les teneurs de marché contre les transactions indésirables dues par une latence inhérente aux moteurs et/ou réseaux de tarification des teneurs de marché.

Patent CA-2584863-A1 (CA)
Inventor: BEDARD MICHEL
IPC: A61B6/00
Filed: 2005-11-09
Abstract: A method and apparatus for reducing motion artifact and spurious noise effects when computing estimates of values representative of at least one physiological parameter of a subject. For motion, measured motion values are compared with a motion threshold and the taking of physiological measurements used for computing the physiological parameter estimate values are either suspended until a measured motion value is under the threshold or a correction function is applied to the physiological measurements, the correction function being based on the measured motion values. As for spurious noise, physiological measurements taken while emitters are turned off are subtracted from physiological measurements taken while emitters are turned on in order to eliminate outside noise contamination.

Abstract: In an apparatus and method for testing a VoIP network (1), a special mode sequence and a telephone number are transmitted on the VoIP network (1). In response to the transmission of the special mode sequence and the telephone number, a network connection is established on the VoIP network (1). Test data is transmitted from a first endpoint (10, 14, 18, 20, 22) of the network connection to a second endpoint (10, 14, 18, 20, 22) of the network connection. In response to the transmission of the test data, either the same or similar test data is returned to the first endpoint (10, 14, 18, 20, 22).  The transmitted and returned test data are processed to determine at least one of: an amount of network delay in the transmitted and returned test data, an amount of jitter in the rate of the returned test data, and an amount of lost test data between the transmitted test data and the returned test data.

Title: Method for remotely monitoring biological data
Inventor: BJOERLIN ANDERS
IPC: G06Q50/00
Filed: 2007-02-09
Abstract: The method is for monitoring biological data in a human body. A sensor (102) senses biological data (103) from a human body (105) and sends the biological data (103) to a control unit (104) that sends the biological data (103) to a communicator (106). The communicator compares the biological data (103) to triggering values (111). The communicator only transmits the biological data when the triggering values have been exceeded by the biological data. The communicator sends an alert signal (114) including the biological data (103) in a dedicated bandwidth (116) to a server (108). A decision rule engine (112) analyzes the biological data and decides which message to send and to which recipient based on the biological data. A medical institution (150) pays a fee (148) to a service unit (138) for accessing the system (100).

Title: Method and apparatus for alleviating nasal congestion
Inventor: WORSOFF MAYA
IPC: A61B17/24
Filed: 2007-09-05
Abstract: The present invention relates generally to the field of treatments for nasal congestion, and in particular, to a method and apparatus for alleviating nasal congestion in a patient by mechanically stimulating the sneezing reflex in the patient to urge drainage of the nasal passageways. The method includes inserting an instrument having a work tip portion provided with at least one filament into the nostril of the patient. The nasal mucosa of the patient is then probed with the at least one filament to stimulate in the patient the sneeze reflex. This probing action causes the patient to sneeze. With the patient's mouth closed, the sneeze urges at least one of mucus, fluid and debris in the nasal passages of the patient to be forcibly expelled through the nostrils of the patient thereby draining the nasal cavity of the patient. The instrument used in the performance of this method includes a handle portion upon which the work tip portion is carried. The handle portion may be integrally formed with the work tip portion or releasably attachable thereto. The instrument is further provided with a physical stop associated with one of the work tip portion and the handle portion to prevent injury resulting from the working tip portion being inserted too deeply into the nasal passages of the patient.
