Patent CA-2321841-C (CA)
Title: Revetement luminescent craquelant pour l'analyse de contrainte
Inventor: WANG YINGSHENG
IPC: C09K11/06
Filed: 1999-10-21
Granted: 2005-12-20
Abstract: Le changement de la morphologie de craquelures d'un revêtement modifie une ou plusieurs caractéristiques de la luminescence émanant de ce revêtement, ce qui permet de déterminer la contrainte exercée sur le matériau d'un substrat au moyen de la mesure de cette luminescence. Ce revêtement luminescent sensible aux contraintes consiste, de préférence, en un revêtement à base de polymère et peut incorporer un ou plusieurs composés luminescents. On peut appliquer ce revêtement afin de créer une couche mince sur le matériau d'un substrat, tel qu'aluminium, acier, polymère ou un matériau composite. Une ou plusieurs caractéristiques de la luminescence émanant du revêtement peuvent alors varier en fonction de la contrainte exercée sur le substrat.

Patent CA-2368060-C (CA)
Inventor: VAN OSENBRUGGEN ANTHONY ALFRED
IPC: B24D7/10
Filed: 1996-12-02
Granted: 2003-10-21
Abstract: Accessories for an angle grinder include a disposable rotary sanding disk having quite large shaped ventilating/viewing apertures, for use with a resilient backing plate also having shaped ventilating apertures. The apertures of one or both parts are shaped so that snagging of the apertures on projections from the work surface is minimized and to facilitate air flow across the work surface during use.   This air flow helps in cooling the work and ejecting detritus, so minimising clogging effects. The ventilating apertures also facilitate viewing the work to be sanded through the spinning disk during the abrasion process, so that operator feedback is immediate. The holes also give the sanding disk more resilience so that a greater area comes in contact with the work and the disk wears more evenly over its abrasive surface.

Title: Device, method and program for encoding/decoding of speech with function of encoding silent period
Inventor: SERIZAWA MASAHIRO
IPC: G10L25/78
Filed: 2000-05-31
Granted: 2006-02-07
Abstract: A speech decoding device of the invention smoothes, in decoding speech signal in a voice-less period, RMS and filter coefficients which is discontinuously transmitted, and provides them to a synthesis filter. Thereby, it is capable of preventing discontinuous changing of the filter coefficient caused by the intermittent transmission of the filter coefficient. As a result, a quality of decoding can be improved. Also, to remove an effect, caused by the smoothing process, from the filter coefficients or the RMS which are transmitted in the past frames, a smoothing factor is adjusted not to perform smoothing while a certain time period (or a certain number of frames) from when a transition is made from a voice period from a voice-less period, or when a decoded feature parameter satisfies a predetermined condition.

Title: Dual wavelength medical diode laser system
Inventor: NEUBERGER WOLFGANG
IPC: A61B18/20
Filed: 2000-07-27
Granted: 2009-11-24
Abstract: A medical diode laser system which allows for simultaneous transmission of a t least two wavelengths radiation of a suitable wavelength for tissue cutting or ablating is coupled into an inner fiber core (16) to produce an output beam with sufficient power density for ablation. Radiation of a suitable wavelength for tissue (1 1) coagulation is introduced into an outer fiber core (15) to produce another output beam with a lower power density appropriate for coagulation. The outer fiber core (15) surrounding the inner fiber core (16) has a refractive index less than the inner fiber core (16), thereby functioning as cladding for the inner core (16). Cladding that has a refractive index that is less than the outer fiber core (15) surrounds the outer fiber core (15). Material functioning as an intermediary cladding separates the outer and inner fiber cores. In th is embodiment, the inner core has a larger refractive index than the inner cladding (35) which in turn has a lower refractive index than the outer core (15).
