Abstract: In one aspect, the invention divides an audio signal into auditory events, each of which tends to be perceived as separate and distinct, by calculating the spectral content of successive time blocks of the audio signal (5-1), calculating the difference in spectral content between successive time blocks of the audio signal (5-2), and identifying an auditory event boundary as the boundary between successive time blocks when the difference in the spectral content between such successive time blocks exceeds a threshold (5-3). In another aspect, the invention generates a reduced-information representation of an audio signal by dividing an audio signal into auditory events, each of which tends to be perceived as separate and distinct, and formatting and storing information relating to the auditory events (5-4). Optionally, the invention may also assign a characteristic to one or more of the auditory events (5-5).

Abstract: Un bogie de wagon de marchandise de chemin de fer comporte une traverse danseuse et une paire de bâtis latéraux, la traverse danseuse étant fixée de façon transversale par rapport aux bâtis latéraux. L'interface de fixation entre les extrémités des essieux et les pupitres de commande des bâtis latéraux permettent le mouvement oscillant latéral des bâtis latéraux de la même façon qu'un bogie ferroviaire à mouvement oscillant, de sorte que la traverse peut se déplacer latéralement par rapport aux bâtis latéraux. La portée de déplacement de la traverse peut être supérieure lorsque le bogie est complètement chargé, par rapport à lorsque le bogie n'est pas chargé. Cela peut se faire à l'aide de lardons de traverse fuselés. Des amortisseurs à friction sont fixés pour fonctionner entre la traverse et les bâtis latéraux. Les amortisseurs à friction peuvent être dotés de garnitures de frein, ou de caractéristiques semblables, du côté qui entraîne les colonnes des bâtis latéraux, sur la face en pente, ou sur les deux. Les amortisseurs à friction peuvent être placés en quatre coins, à chaque extrémité de la traverse danseuse. Les amortisseurs à friction peuvent comprendre des éléments dotés de deux degrés de liberté de rotation, de façon à pouvoir permettre aux éléments de friction de s'adapter aux changements d'orientation angulaire entre la traverse et les bâtis latéraux pendant les axes de tangage et de lacet.

Granted: 2010-02-09
Abstract: Flow meter electronics (302) are described for providing a flow rate of a material flowing through a flow meter sensor (10) of a Coriolis flow meter (300). The flow meter electronics (302) comprise a processing system (304) and a single output port (306). The processing system (304) receives pick-off signals from the flow meter sensor (10) and processes the pick-off signals to determine the flow rate. The processing system (304) receives an instruction for a frequency output signal or a digital communication protocol signal. If the instruction is for a frequency output signal, then the processing system (304) processes the flow rate to generate a frequency output signal and transmits the frequency output signal over the single output port (306). If the instruction is for a digital communication protocol signal, then the processing system (304) processes the flow rate to generate a digital communication protocol signal and transmits the digital communication protocol signal over the single output port (306).

Patent CA-2508774-C (CA)
Inventor: WEI NING
IPC: G01N33/543
Filed: 2003-10-29
Granted: 2011-07-05
Abstract: A membrane-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes a chromatographic zone on which is disposed a plurality of microporous particles. The chromatographic zone can effectively reduce the "hook effect" in a simple, efficient, and relatively inexpensive manner. In particular, the plurality of microporous particles allows larger-sized analyte/probe complexes to reach the detection zone before the uncomplexed analyte. Because the uncomplexed analyte is substantially inhibited from competing with the complexes for the binding sites at the detection zone, the incidence of "false negatives" may be limited, even at relatively high analyte concentrations.
