Patent CA-2133849-C (CA)
Inventor: ERDOGAN TURAN
IPC: G02B1/00
Filed: 1994-10-05
Granted: 1999-08-17
Abstract: The present invention is predicated upon the discovery by applicants of a relationship describing thermal decay of radiation-induced index changes and a mechanism which permits stabilization by accelerated aging, Specifically, the induced index change decays in proportion to 1/(1 + At .alpha.) where A and .alpha. are functions of temperature, and the decay can be accelerated by heat treatment.  As a consequence, the extent of decay can be determined for arbitrary time and temperature and, significantly, an appropriate heat treatment can be scheduled for making a device stable within predeterminable limits.

Title: Voice activity detection driven noise remediator
Inventor: JANISZEWSKI THOMAS JOHN
IPC: G10L21/02
Filed: 1994-12-22
Granted: 1999-05-11
Abstract: A method and apparatus for improving sound quality in a digital cellular radio system receiver.  A voice activity detector uses an energy estimate to detect the presence of speech in a received speech signal in a noise environment.  When no speech is present the system attenuates the signal and inserts low pass filtered white noise.  In addition, a set of high pass filters are used to filter the signal based upon the background noise level.  This high pass filtering is applied to the signal regardless of whether speech is present.  Thus, a combination of signal attenuation with insertion of low pass filtered white noise during periods of non-speech, along with high pass filtering of the signal, improves sound quality when decoding speech which has been encoded in a noisy environment.

Granted: 1998-05-19
Abstract: A hybrid inflator for a vehicle passenger restraint system comprises a center tie having upper and lower ends, and a curved, continuous vessel wall secured to the upper and lower ends of and surrounding the center tie to define a pressure chamber storing inert compressed gas. The center tie defines a combustion chamber extending from the lower end thereof, the combustion chamber receiving pyrotechnic gaseous heat source material and a squib for igniting it. The center tie further defines a directional inlet port extending from the combustion chamber into the pressure chamber and a rupturable diaphragm seals the inlet port until ignition of the pyrotechnic generant. The center tie also defines a directional outlet vent extending from the pressure chamber adjacent the upper end of the center tie, the directional outlet vent being oriented substantially opposed the inlet port. The outlet vent is part of an outlet passage from the pressure chamber through the upper end of the center tie, including an orifice cavity and outlet orifice, oriented to provide further turns in the gas flow path. A rupturable diaphragm seals the outlet passage until ignition of the gas generant. A diffuser provides an additional change of direction of the outlet path.
Patent CA-2146171-C (CA)
Inventor: SCHIEFER BERNHARD
IPC: G06F16/2453
Filed: 1995-04-03
Granted: 2000-01-11
Abstract: A method for estimating key cardinalities for a grouping of columns for use by a query optimizer in a relational database management system (RDBMS).   The grouping of columns or key results from a grouping operation or duplicate  removal operation in a query.   The method accounts for the effects of local predicates on the columns and also the effects of local predicates on columns not belonging to the grouping. The method also utilizes selected index key cardinalities which are available in the catalog of the RDBMS for estimating the cardinalities of columns groupings and accounts for the effects of local predicates on the index key cardinalities.   The method also includes a number of additional operations which utilize other attributes in order to produce an accurate estimate of the key cardinality.

Title: Snowshoe
Inventor: LIAUTAUD JEFFREY T
IPC: A63C13/00
Filed: 1995-05-05
Granted: 1999-08-24
Abstract: A snowshoe includes a perimeter frame carrying sheet-type floatation and having a hinge rod secured transversely of the frame by hinge rod straps.  A foot plate is pivotally mounted on the hinge rod and supports a binding to attach the snowshoe to a user's shoe or the like.   A bearing sleeve is disposed between the hinge rod and a retainer plate secured to the underside of the foot plate.   The hinge rod, bearing sleeve, retainer plate,  and hinge rod straps,  act  independently or cooperatively to vary the frictional resistance to relative rotation between the foot plate and hinge rod,  and thereby provide  a  shock  absorber effect.   Various  features  enable variation of the shock absorbing characteristics to accommodate different uses of the snowshoe and different characteristics of the user.   Other features provide improved discharge of snow which accumulates on the snowshoe, and improved retention of the user's boot longitudinally within the binding.

Title: System and method for reducing false positives in atrial fibrillation detection
Inventor: KIM JAEHO
IPC: A61N1/39
Filed: 1995-06-30
Granted: 2000-04-18
Abstract: An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion after first determining if there is an absence of potential atrial fibrillation. A sensor associated with the atria of the heart senses activity of the heart and generates a cardiac signal and a first detector detects cardiac events from the cardiac signal. A second detector responsive to time spans between immediately successive detected cardiac events which are greater in duration that a preselected interval detects for an absence of potential atrial fibrillation. An atrial fibrillation detector detects for atrial fibrillation if the second detector fails to detect an absence of atrial fibrillation, and a cardiovertor applies cardioverting electrical energy to the atria when the atria are in fibrillation.

Abstract: Carte pliable en laminé (10) pourvue de charnières améliorées (15a), divisée en deux ou plusieurs panneaux séparés (11a) et imprimée d'un seul côté. L'espace (12) entre les panneaux (11a) est une zone non imprimée qui servira de charnière (15a). Des fentes (13) sont découpées, le long de la zone non imprimée en laissant des languettes (12) reliant deux panneaux adjacents. Les fentes (13) une fois découpées dans la zone non imprimées de la carte, cette dernière passe dans une machine de laminage, la direction des charnières (15a) étant parallèle à l'avance de la machine. En raison de l'étroitesse des fentes (13), les films de laminage du recto et du verso de la carte emprisonnent de l'air dans les fentes (13). L'air emprisonné contribue à réduire le frottement au niveau des charnières, ce qui accroît la longévité de la carte.
