Patent CA-2227416-A1 (CA)
Inventor: GRASFIELD JAMES A
IPC: A61B7/04
Filed: 1996-07-19
Abstract: L'invention concerne un stéthoscope électronique pouvant fonctionner en différents modes pour traiter des signaux acoustiques et fournir des signaux filtrés utiles pour effectuer des diagnostics. Dans un mode de fonctionnement, le stéthoscope ne fournit sensiblement que les signaux acoustiques provenant de l'activité biologique du coeur. Dans un autre mode de fonctionnement, le stéthoscope acoustique ne fournit sensiblement que les signaux acoustiques provenant de l'activité biologique des poumons. Dans un autre mode de fonctionnement encore, le stéthoscope électronique amplifie, de manière très forte, les bruits normaux du coeur et les bruits anormaux du coeur, pour faciliter le diagnostic d'anomalies cardiaques. Le stéthoscope électronique fonctionne d'une manière similaire à celle d'un stéthoscope acoustique conventionnel et il a des caractéristiques spectrales similaires, ce qui permet à un utilisateur ayant l'expérience d'un stéthoscope acoustique, d'utiliser sans difficulté le stéthoscope électronique.

Title: Inline solid state polymerization of pet flakes for manufacturing plastic strap
Inventor: NELSON JAMES P
IPC: C08L67/02
Filed: 1998-01-26
Abstract: The present invention describes a process of making strap using both post consumer and non-post consumer PET of wide distribution intrinsic viscosity (IV) through direct solid state polymerization in a flaked state to product PET with increased, heterogenous IV suitable for high performance strap extrusion. The process increases the IV of post-consumer resins, consisting principally of polyethylene terephthalate  (PET), by chopping the post-consumer plastic into flakes and chunks, rolling the flakes and chunks, preheating the flakes, and further heating the flakes and chunks preheated flakes in an atmosphere of hot nitrogen gas, thereby increasing  the  intrinsic  viscosity.  PET  polymers  having  increased viscosities according to the present invention provide a polymer useful in manufacturing high performance strap.

Title: Satellite signal receiver with detector of incoherence between code phase and carrier frequency measurements
Inventor: ARETHENS JEAN-PIERRE
IPC: G01S1/00
Filed: 1997-06-03
Abstract: The invention concerns GPS receivers, in particular those located on fixed ground stations and used in differential systems for measuring position. To eliminate as far as possible multiple traverse influence on the precision of the measured position, it is proposed to detect if the position measurements are coherent with the speed measurements, the coherence being measured by the difference variations V¿i? - dPRC¿i?/dt, where V¿i? is the relative speed measured on the axis of the i?th¿ satellite, and dPRC¿i?/dt is the variation with time of the measured position. If the coherence is not sufficient, the position variations do not correspond to the measured speed, it can be considered that the measurement on this satellite is erroneous, and this satellite is eliminated. In the presence of multiple traverse, the above difference must be seen to vary periodically. This variation detection can done by a Fourier transform on a sufficient number of samples.
