Abstract: Polarized electric charge storage devices economically provide high availabl e capacitance. The present invention directly employs polarized electrical charge storage (PECS) devices such as polarized capacitors (612, 614) or electrochemical batteries in general AC applications with a novel circuit topology. In one embodiment, an anti-series configuration of first (612) and  second (614) PECS devices are used within an AC network for enhancing operation of the AC network. At least one DC source (616, 618) is provided f or maintaining the PECS devices forwardly biased while they are subjected to an  AC signal. The AC signal, which drives an AC load (620), is applied to the anti-series devices (610). The devices are sufficiently biased by the at lea st one DC voltage source so that they remain forwardly biased while coupling th e AC signal.

Patent CA-2398815-A1 (CA)
Title: Dry powder inhaler
Inventor: CHEN JEFFREY
IPC: A61M15/00
Filed: 2001-01-31
Abstract: A dry powder inhaler (20) has a dispersion chamber (30) containing beads (40).  A dose of dry powder (142) is released into the chamber, or into an inlet (26) tangentially joining into the chamber. As the patient inhales on a nosepiece or mouthpiece (22), air moves circularly through the dispersion chamber to drive the beads. The beads roll, bounce, and collide repeatedly with the drug particles on the chamber surfaces or on the beads. The smaller active drug particles are separated from the larger carrier particles and from each other, and a powder aerosol is created and inhaled by the patient. The beads are preferably lightweight, so that they can be rapidly accelerated and moved, even with nominal inspiration. The flow resistance of the inhaler is also reduced via the beads, allowing greater air flow and powder dispersion, without any increased effort by the patient.

IPC: G01N33/72
Filed: 2002-10-09
Abstract: The present invention provides a method of monitoring calibration of a spectrophotometric apparatus that comprises one or more calibration algorithms for one or more analytes. This method comprises measuring absorbance of a quality control material with the apparatus to obtain a measurement, where the quality control material exhibits an absorbance spectrum characterized as having a negative slope for a continuous spectral segment from about 5 nm to about 200 nm in length, and where the spectral segment includes a principal calibration wavelength for the one or more analytes.

Title: Decalages de synchronisation des codes courts dans un systeme cdma
Inventor: EMMONS THOMAS PETER JR
IPC: H04B7/185
Filed: 2001-06-22
Abstract: Cette invention se rapporte à un réseau de communication cellulaire CDMA (400), qui comprend un ou plusieurs avions (410) relayant des signaux de canal de commande et de canal pilote entre des stations émetteurs-récepteurs de base (BTS) (406 et 413) et des unités d'abonnés (401). La station (BTS) transmet aux unités d'abonnés via le canal de commande une liste de candidats à un transfert intercellulaire. Cette liste de candidats à un transfert intercellulaire identifie les stations BTS candidates sur lesquelles l'unité d'abonné pourrait théoriquement se transférer. Cette liste indique en outre avec quels décalages les unités d'abonnés doivent rechercher les codes courts transmis par les stations BTS candidates via le canal pilote. Sur la base de la longueur de trajet entre la station BTS, l'avion et l'unité d'abonné, les stations BTS candidates génèrent elles-mêmes leurs codes courts avec un décalage qui est égal ou antérieur au décalage rapporté par l'unité d'abonné par une valeur delta. Les stations BTS peuvent en outre imposer un retard variable aux bits des codes courts ainsi générés, en vue de compenser les variations de retard de trajet, pendant que l'avion suit sa trajectoire de vol.
