Patent CA-2116341-A1 (CA)
Inventor: WESTON TERENCE E
IPC: G01N21/29
Filed: 1992-08-21
Abstract: A needleless injector comprises a liquid metering chamber (31, 131) having an outlet orifice (21, 121), a piston (7, 107) slidable within the metering chamber, and a rod (6, 106) which is arranged to strike one end of the piston to force liquid through the outlet orifice. The injector is in two parts (1, 2; 101, 102) which are biassed away from one another, and the front one of which carries the outlet orifice. Actuation only occurs when one part is sufficiently urged towards the other by the user.

Abstract: An apparatus and method for echo cancellation in voice-messaging and voice-response systems, to enhance recognition of received DTMF and voice signals, comprising an efficient software echo canceller using adaptive digital filtering techniques. The voice messaging system (1, fig. 1) includes analog telephone line interface modules (24) which provide digitized voice data to a digital signal processor (DSP) chip.  A transmit data line (204, fig. 3) and a receive data line (202) are each coupled to a cancel module (208) with a cancel filter and an adapt/window module (220) with an adaptive digital filter.  The cancel filter causes echo cancellation on the transmit data line; the adapt/window module monitors buffered transmit data in non-real time, without di-rectly causing cancellation to occur, and selectively transfers an adjacent window of filter coefficients to the cancel filter under control of an adaptation control (230) coupled to the adapt/window module.  The control identifies a plurality of frames meeting a power criterion and passes the frames to the adaptive filter, which adapts on taps in frame segments during all available DSP real time, using a "cycle steal" feature for testing whether additional DSP processor cycles are available to use for echo cancella-tion.

Filed: 1992-08-28
Abstract: A muffler for muffling noise in a fluid flow, such as exhaust gases from an internal combustion engine comprises a chamber (10), loudspeakers (7) for injecting anti-noise into the chamber under the control of processing circuitry (12) in dependence upon residual noise detected by a microphone (11). The gas flows from an inflow pipe (5) to an outflow pipe (3) past a radial aperture (13) that produces an acoustic coupling between the chamber (10) and the gas flow, to allow the anti-noise to mix with noise in the gas flow and produce noise cancellation. The coupling is so arranged that the chamber (10) becomes pressurised by the gas flow. in use. so as to restrict hot gas flow through the chamber and thereby provide an essentially benign environment for the loudspeaker.

Date Jun. 10, 1993Nanosols and process for preparing the same allow colloidally dispersed solutions of scarcely water-soluble active substances to be stabilized with gelatin or its derivatives, by partly or fully setting the iso-ionic point (IIP, equivalent to a neutral charge) between the gelatin and the surface charged active substance particles. In order to neutralize the charge of the system composed of active substance particles and gelatin, the surface charge of the particles is compensated by a corresponding opposite charge of the gelatin molecules. For that purpose, a determined charge in relation to the isoelectric point (IEP) and the pH value of the solution is set on the gelatin molecules. By stabilizing in this way the practically monodispersed state thus generated, the Ostwald maturation of the colloidal particles of scarcely soluble active substance is strongly reduced. A new form of pharmaceutical administration having new properties can thus be obtained with generally scarcely water-soluble inorganic and organic compounds, in particular medicaments with a problematic bioavailablity. Preferred medicaments are glibenclamide and 3-indolylacetic acid derivatives, such as indomethacin or acemetacin.

Filed: 1994-07-22
Abstract: The present invention provides a marker detection and thinning process for a photocopier which is executed during a single scan of a document and does not require a prescan of the document. The system realtime analyzes pixel image data, which is stored in a memory during the scanning process, to detect a marker line of a predetermined color and to thin the marker line. This analysis begins with image data stored in the memory that corresponds to a first pixel. The first pixel is associated with the scanline being presently scanned. It is determined if the image data of the first pixel represents a color that is equivalent to the predetermined color. Marker data is then stored in a buffer at a location corresponding to the first pixel if it is determined that the image data of the first pixel represents a color that is equivalent to a predetermined marker color. The data, stored in the buffer at a second pixel location, is analyzed. The second pixel is associated with a scanline that is prior in time to the scanlineof the first pixel. It is determined if the data at the second pixel location ismarker data. Also, the data stored in pixel locations adjacent to the second pixel location is analyzed to determine if this data is marker data. The marker data at the second pixel location is eliminated if it is determined, upon examining data of pixel locations adjacent to the second pixel location, that the elimination of this marker data would maintain the connectivity of the marker line. However, the data at the second pixel location is maintained if it is determined that, upon examining the data of pixel locations adjacent to the second pixel location, the elimination of this marker data would cause disconnectivity of the marker line.

Abstract: Un appareil de communication capable de mesurer des niveaux de signaux de porteuses utilisés dans les zones adjacentes au cours de télécommunication avec une petite échelle de circuit, et capable d'émettre/recevoir simultanément des signaux de système AMRF à travers une pluralité de canaux de communication. Tous les signaux de transmission reçus par les canaux de communication en cours d'utilisation sont entièrement convertis en un signal intermédiaire par un mélangeur. Le signal intermédiaire est détecté en quadrature et ensuite converti A/N en signaux de canal I/Q par des convertisseurs A/N. Par la suite, les signaux de canal I/Q numériques sont convertis en fréquence par des circuits de conversion de fréquence de telle manière que les fréquences centrales de ces signaux de canal I/Q deviennent égales à zéro, deux ensembles de signaux de canal I/Q peuvent être démodulés par deux des ensembles de circuits de démodulation. Dans le cas contraire, l'un de ces signaux de canal I/Q est démodulé par un seul circuit de démodulation, et le niveau de l'autre est détecté par le circuit de détection de niveau.
