Abstract: L'invention concerne un procédé et un système permettant d'établir des liaisons vers des abonnés mobiles occupés dans un réseau de radiocommunications. Le système comprend un centre de commutation mobile passerelle (G-MSC) destiné à fournir des fonctions de commutation à une station mobile (MS) d'une zone de desserte locale, un registre de localisation nominal (HLR) donnant au G-MSC la localisation de la station mobile, un centre de commutation mobile visiteur (V-MSC) destiné à fournir des fonctions de commutation à la station mobile lorsque cette dernière est en itinérance hors de la zone de desserte locale, et un point de commande de service (SCP) qui comprend une logique de services permettant de tenter périodiquement d'appeler la station mobile pour vérifier si cette dernière est occupée. Lorsque la partie appelante tente d'appeler une station mobile occupée, elle peut demander un service de rappel automatique. Le G-MSC libère toutes les lignes réseau partant de la partie appelante et de la station mobile et le signale au SCP qui fait périodiquement une tentative d'appel pour savoir si la station mobile est libre. Et si la station mobile est libre, le G-MSC connecte l'appel entre la partie appelante et la station mobile.

Title: Noise cancellation system for active headsets
Inventor: OGLE EDWARD F
IPC: A61F11/14
Filed: 1998-07-30
Granted: 2005-10-11
Abstract: An active headset system is provided with either two stereo jack plugs or a six pin connector (T1, T2, T3, T4, T5, T6) to provide compatibility with existing socket configurations for personal stereo equipment and headsets (28, 30) on aircraft. The number of connections between the active headset and the remote noise cancellation circuitry is reduced from eight to six through the use of a common contact, having a controlled impedance, that serves as an input connection to corresponding terminals of the two earphones of the active headset. According to another aspect of the present invention, the transients associated with plugging in or unplugging stereo jack plugs or up to a seven pin connector into an active headset may be overcome by a transient detector in the noise cancellation circuitry. Yet another aspect of the present invention concerns the powering of the noise cancellation circuitry whether the noise cancellation circuitry is placed inside the active headset or at least partially internal to a remote external device.

Filed: 1998-05-20
Granted: 2003-12-23
Abstract: The present invention shows that DNA vaccine vectors can be improved by removal of CpG-N motifs and optional addition of CpG-S motifs. In addition, for high and long-lasting levels of expression, the optimized vector should include a promoter/enhancer that is not down-regulated by the cytokines induced by the immunostimulatory CpG motifs. Vectors and methods of use for immunostimulation are provided herein. The invention also provides improved gene therapy vectors by determining the CpG-N and CpG-S motifs present in th e construct, removing stimulatory CpG (CpG-S) motifs and/or inserting neutralizing CpG (CpG-N) motifs, thereby producing a nucleic acid construct providing enhanced expression of the therapeutic polypeptide. Methods of use for such vectors are also included herein.

IPC: G06T7/70
Filed: 2000-05-02
Granted: 2008-07-08
Abstract: The present invention concerns a method for evaluating a scale factor and a rotation angle in image processing and more particularly digital image processing. The method includes the steps of first providing an input image, an then reducing the input image to provide a smaller image. The smaller image is scaled according to a plurality of factors to produce a plurality of scaled images and is also rotated according to a plurality of factors to produce a plurality of rotated images. The scaled images in the rotated images are then placed into a mosaic which is arranged by scale and rotation. A referenced template is provided and the referenced template is correlated with the mosaic of scaled and rotated images to provide a scale factor and a rotation angle based on the position in the mosaic of the high score relation value between the reference template and the scaled and rotated images. The method is more efficient in that it reduces the amount of computations required to obtain useful results. The method also does not require object centering prior to performing the analysis and does not require complex mathematical expansion of the object under analysis.

IPC: G01B7/004
Filed: 2001-07-18
Granted: 2009-09-01
Abstract: A system for determining the position of a medical device having a sensor comprises a plurality of field radiators wherein each field radiator has a plurality of radiator elements. Each radiator element generates a magnetic field such that each magnetic field is distinct from one another due to the use of a different frequency through simultaneous energizing of the radiator elements. A signal processor is operatively connected to the field radiators and the sensor of the medical device for receiving a sensing signal from the sensor indicative of the magnetic field sensed at the sensor. The sensing signal defines a measured magnetic field at the sensor. The signal processor also has a desired range of accuracy for the system which is stored therein. The signal processor includes an initial position estimator for establishing an initial position estimate for the sensor; a magnetic field calculator for calculating the magnetic field at the initial position estimate; a steepest descent calculator for calculating a steepest descent of the calculated magnetic field to the measured magnetic field; and a new position estimate calculator for calculating a new position estimate of said sensor based on said steepest descent. The signal processor determines the position of the sensor when the new position estimate of the sensor is within the desired range of accuracy for the system. Alternative field radiator arrangements are also provided in conjunction with a novel algorithm utilizing a global convergent technique.
