Patent CA-2650419-A1 (CA)
Title: Method for the time scaling of an audio signal
Inventor: SALAMI REDWAN
IPC: G10L25/93
Filed: 2007-04-27
Abstract: A method for the time scaling of a sampled audio signal is presented. The method includes a first step of performing a pitch and voicing analysis of each frame of the signal in order to determine if a given frame is voiced or unvoiced and to evaluate a pitch profile for voiced frames. The results of this analysis are used to determine the length and position of analysis windows along each frame. Once an analysis window is determined, it is overlap-added to previously synthesized windows of the output signal.

Inventor: STAGGS JAMES W
IPC: A61F9/007
Filed: 2007-07-30
Abstract: A method and apparatus for precisely controlling particle movement relati ve to a phacoemulsification needle tip is provided. The design monitors actu al vacuum present and calculates a pulse shape amplitude waveform proportion al to the amount of measured vacuum. An increase in vacuum indicates that th e handpiece/needle is becoming occluded by a large particle. The present des ign determines whether additional power is required to bump or move a large particle away from the needle tip. The present design may employ a control l oop that senses and continuously monitors vacuum. The design may dynamically vary the amount of ultrasonic energy delivered to the surgical area in resp onse to the observed actual vacuum, and can actively vary the amount of powe r delivered to the surgical area based on the size of the particle and the r esultant vacuum realized.

Inventor: RON IZAC
IPC: A47K11/06
Filed: 2008-08-15
Abstract: The invention provides an inflatable receptacle which may easily be brought along, and which in the inflated state may serve as a stable seat with comfortable seat height for a person. This is achieved by an inflatable receptacle which is peculiar in that the inner membrane side and the outer membrane side are interconnected by at least one membrane joint, preferably by welding the two membrane sides at the centre part of the receptacle, where the at least one membrane joint extends partially or entirely between the lower and upper ends of the receptacle. Great stability is achieved hereby, as optimal possibility for transferring an action of force applied to the upper end of the receptacle in parallel with the support face is created in order to absorb the action of force in a large part of the support face placed upon the base. This improved ability of transferring actions of force to the base arises because shear forces by disc action are transferred along a membrane joint according to the invention between the partial air chambers produced by establishing the membrane joint.

Abstract: L'invention concerne un agent antibactérien comportant comme produit actif un tissu hémostatique de contact ayant un pH acide combiné à de la polyvidone iodée, le tissu hémostatique de contact étant de la cellulose oxydée régénérée ou non ré-générée. Elle concerne également un dispositif de protection actif des berges d'incision intégrant un tel un agent antibactérien. Le demandeur a maintenant mis en évidence de manière surprenante que la combinaison de cellulose oxydée régénérée ou non régénérée avec de la polyvidone iodée donnait une inhibition bactérienne supérieure à la simple utilisation de la cellulose oxydée régénérée ou non régénérée isolée ou de la polyvidone iodée isolée. Il s'agit donc d'un effet synergique qui aboutit à la constitution d'un nouvel agent à la fois hémostatique et antibactérien très puissant.
