Patent CA-2309944-A1 (CA)
Inventor: MILLS RANDELL L
IPC: G01R33/24

Abstract: Cette invention consiste à générer une carte tridimensionnelle de la susceptibilité magnétique d'un objet comprenant un patient placé dans un champ magnétique, à partir d'une carte tridimensionnelle de flux magnétique haute fréquence résonant, extérieur au patient. On détermine la susceptibilité magnétique de chaque voxel à partir du glissement de la fréquence de Larmor imputable à la présence du voxel dans le champ magnétisant. Les variations d'intensité du champ haute fréquence transversal dans l'espace servent à déterminer les coordonnées de chaque voxel. Le champ haute fréquence est un champ proche en dipôle servant d'élément de base pour former une reconstruction unique. La fonction du système géométrique correspondant au dipôle caractéristique des variations d'intensité du champ à haute fréquence dans l'espace est une bande passante telle que k¿??=k¿z?. Dans cette limite, la reconstruction de chaque volume élémentaire intervient indépendamment, en parallèle avec tous les autres volumes élémentaires, et ce, de manière que le temps de balayage ne dépasse pas la durée du signal de précession libre (FID) nucléaire. Le calcul de la susceptibilité magnétique (par fréquence de Larmor interposée) intervenant indépendamment de la reconstruction spatiale (par fréquence fonction géométrique de système interposée), il devient possible de faire une reconstruction numérique par référence au modèle analogique. Ces spécificités permettent d'utiliser ce nouveau type d'imagerie par résonance magnétique (IRM) pour générer, d'une part en temps réel des images anatomiques tridimensionnelles a haute résolution, et d'autre part des images construites sur des paramètres physiologiques et ne présentant sensiblement pas d'altérations imputables à des artefacts liés aux mouvements.

Abstract: Software abstraction components provide a means for having service handlers which can provide services in response to a request received from a requestor in a particular protocol regardless of the particular protocol. A number of protocol proxies are capable of receiving requests, each protocol proxy only being able to receive a request in a particular protocol.      Upon receiving a request, a protocol proxy decomposes the request into its parameters and stores the parameters as name/value pairs in a data structure. A broker, another software component, has a list or register of non-protocol specific service handlers. The broker asks the service handlers, in a particular order, to consider the name/value pairs in the data structure. If a service handler refuses to handle the request as decomposed into name value pairs, the broker asks the next service handler. If a service handler accepts the request, the service handler performs the requested service and adds response data, if appropriate, to the data structure. If the response data is to be returned to the requestor, the protocol proxy translates the data into the original protocol and returns the translated data to the requestor.

Title: Methods for exogenous, internal controls during nucleic acid amplification
Inventor: AOYAGI KAZUKO
IPC: G01N33/53
Filed: 1999-03-27
Abstract: Reporter-quencher probe assays of nucleic acid amplification, such as PC R, are rendered more meaningful by the addition of internal control reagents.  An internal control polynucleotide is amplified with internal control prime rs and the product is measured by correlation with increased fluorescence by polymerase mediated-exonuclease cleavage or hybridization of the internal control probe. Probes specific for target and internal control polynucleotides are labelled with spectrally resolvable reporters, allowing for concurrent detection and measurement of target and control amplification. A kit of all PCR reagents can be dispensed into reaction chambers in a high-throughput system for rapid and accurate nucleic acid amplification assay, with real-time or end-point measurements.  Fluorescent signals correlated to target and internal control levels are spectrally resolvable and measured concurrently. A non-extending oligonucleotide or nucleic analog "block", complementary to the internal control polynucleotide, is added to the amplification mixture to preclude amplification of the internal control polynucleotide and function as an internal negative control. The amplification control reagents, kits, and     methods of the present invention provide positive and negative control tests occurring within, and measurable within, the reaction chamber.   -57-

Abstract: The invention relates to an armature bearing for proportional magnets or switching magnets used in the area of hydraulics or pneumatics. The armature of a magnet of this type is guided inside a pressure pipe by two rings which are welded into said pressure pipe. Said rings project over the inner periphery of the pressure pipe with a ring bearing and guide the armature with minimum friction. The ring facing towards the pole core is the separating ring which consists of non-ferromagnetic material. This separating ring concentrates the magnetic flux between the pole core and the armature. The second separating ring, which is situated on the other end section of the pressure pipe, may advantageously also consist of a non-ferromagnetic material such as brass or non-ferromagnetic steel, for production-related technical reasons. The inventive bearing can either be produced by welding suitable bearing rings with inwardly projecting ring bearings in sections of pressure pipes or by applying rings by build-up welding in grooves with a V-shaped cross-section in a solid rough-turned component and forming the pressure pipe with the inwardly projecting ring bearings by turning out said component. The ring bearings can be equipped with axial oil grooves.

Title: Circuit and method for the adaptive suppression of noise
Inventor: SCHAUB ARTHUR
IPC: H04R25/00
Filed: 2001-01-24
Abstract: The circuit for the adaptive suppression of noise is a component part of a digital hearing aid, consisting of two microphones (1, 2), two AD - converters (3, 4), two compensating filters (5, 6), two retarding elements (7, 8), two subtractors (9, 10), a processing unit (11), a DA - converter (13), an earphone (15) as well as the two filters (17, 18). The method for the adaptive suppression of noise can be implemented with the indicated circuit. The two microphones (1, 2), dependent on their spatial arrangement or their directional characteristics and dependent on the location of the acoustic signal sources, provide two differing electric signals (d1(t), d2(t)), which are digitalized in the two AD - converters (3, 4) and pre- processed together with the two fixed compensation filters (5, 6). Following subsequently are the two filters (17, 18) arranged symmetrically crosswise in forward direction with the adaptive filter coefficients (w1, w2). The filter coefficients (w1, w2) are calculated by means of a stochastic gradient procedure and updated in real time while minimizing a quadratic cost function consisting of cross-correlation terms. As a result of this, spectral differences of the input signals are selectively amplified. With a suitable positioning of the microphones (1, 2) or selection of the directional characteristics, therefore the signal to noise ratio of output signals (s1, s2) in comparison with that of the individual microphone signals (d1(t), d2(t)) can be significantly increased. In preference, one of the two improved output signals (s1, s2) within one of the processing units (11, 12) is subjected to the usual processing specific to hearing aids, sent to one of the DA - converters (13, 14) and acoustically output once again through one of the earphones (15, 16). In the case of the invention presented here, four additional cross-over element filters (19-22) carry out a signal-dependent transformation of the input - and output signals (y1, Y2; s1, s2), and solely the transformed signals are utilized for the updating of the filter coefficients (w1, w2). This makes possible a rapidly reacting - and nonetheless calculation-efficient updating of the filter coefficients (w1, w2) and in contrast to other methods only causes minimally audible distortions.

IPC: H03H9/145

Abstract: SAW devices such as interdigital transducers (IDTs) have been widely used in RADAR applications and as filters. An IDT produces a SAW when excited by a single electrical pulse and can be fabricated to embody a code, which code provides for a passive autocorrelation of a SAW input to the IDT and thereby lends itself to further application as a signal generator in a communication device. However, conventional SAW expanders and compressors typically have insertion losses greater than 20 dB, which can have a profound effect on an RF link budget in a communication system.  Insertion losses are drastically reduced by using a single phase unidirectional transducer (SPUDT-type) instead of a conventional IDT as a SAW expander/compressor. A SPUDT-type reflects SAW components which are lost in conventional IDT designs so that a stronger SAW is directed toward a transmission element. In a receiver, a SPUDT-type directs a stronger S,AW toward a compressor IDT. A communication system based on SPUDT-type techniques would be low-cost, low-power, small and simple alternative to known short range communications schemes, including for example the Bluetooth TM solution.  Operation of a SAW system at a frequency of 2.4 GHz is contemplated.
