Title: Improved speech recognition by modifying a pronunciation
Inventor: FANTY MARK
IPC: G10L15/06
Filed: 2001-02-09
Abstract: An approach for automatically modifying a pronunciation dictionary in a spee ch recognition system (104) based on patterns of alternate pronunciations is described. A representation of the pronunciation dictionary (112), such as a  plurality of dynamically linked phoneme values, is obtained. One or more pattern definition (124) are obtained. The pattern definition (124) specify zero or more phonemes to be substituted for zero or more phonemes of all wor ds in the pronunciation dictionary (112). The linked phoneme values are modifie d by adding, for each path of each word, alternate paths that use each of the substitute phonemes according to the pattern definitions (124), thereby creating an expanded set of dynamically linked phoneme values. One or more best paths through the expanded set of phoneme values are determined for eac h of the example pronunciations and used to find the overall best path(s).</SD OAB>

Inventor: INGRAHAM DOUGLAS WELLINGTON
IPC: B60P3/34
Filed: 2002-09-24
Abstract: The present invention provides a weatherproof, compact, light weight and lockable reconfigurable utility trailer of small enough dimension that it may be easily towed by a vehicle as small as a sub-compact automobile and may be conveniently stored in the vertical position on the storage dolly. The trailer employs forward and rear hinged end gates to, which are affixed a quick disconnect tent frame which in conjunction with a ride support assembly comprises the camper tent frame. In addition to the camper trailer is a free standing extra room which employs the trailer lid as a floor and uses a similar tent framework and cover. With the camper tent frame and exterior cover removed the trailer becomes a flat deck of sufficient dimension to transport cargo such as building materials, furniture, or dirt bikes. Also employed are quick disconnect bike racks mounted to the trailer to which the bikes may be locked. Reconfiguration of the trailer from one mode to another is accomplished easily and without tools or mechanic skills.

Abstract: An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor (18) for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor (16) coupled to the sensor (18) for activating the sensor (18) on a first periodic basis to measure the device parameter. The microprocessor (16) includes a memory for storing the generated data signal representing the measured parameter. A  transmitter/receiver (21) is coupled to the microprocessor (16). The microprocessor (16) periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter.  In one embodiment, the device is a tire tag (14) mounted inside a tire that measure tire data and transmits that data to a remote source (26) in response to an interrogation request, an alert condition, or automatically on a periodic basis.

Title: Method and device for measuring airflows through hvac grilles
Inventor: MODERA MARK PETER
IPC: G01F1/36
Filed: 2003-02-03
Abstract: A fan powered by a controlled external energy source and a flow measurement device measure the airflow exiting or entering grilles/registers of an HVAC system without impeding the airflow being measured. A flow straightening element is preferably employed to overcome any effects of a non-uniform or swirled airflow profile on the tan. Preferably, the RPM of the fan is measured to determine the airflow. The RPM/flow calibration of the tan is insensitive to pressure differentials or the fan is a pressure-sensitive fan submitted to appropriate pressure differentials. Alternatively, the voltage or current supplied to the external energy source is used to determine the airflow. Finally, the pressure differential across the flow straightening element can be measured to determine airflow, eliminating the impact of pressure differential across the flow measurement device and fan.

Title: Pump amplitude modulation for distributed raman amplifier
Inventor: PARK DAVID W
IPC: H04B10/296
Filed: 2001-10-05
Abstract: A power supply for a pump laser in a distributed Raman amplifier is modulated with a small amount of amplitude modulation. This amplitude modulation transfers to the traffic wavelengths and is detected at a Raman amplifier control system. Given knowledge of the signal level of the modulation that was applied, the gain of the distributed Raman amplifier may be determined. The Raman amplifier control system may then control the power supplied to the pump laser to result in a specific gain, thus providing closed loop control.  Additionally, a distinct amplitude dither may be placed on each of the traffic wavelengths at the transmitting end of an optical communication system. At the receiving end, a given traffic wavelength may be examined for the presence of amplitude dither associated with other traffic wavelengths.
Patent CA-2422221-A1 (CA)
Inventor: WIND DANIEL
IPC: H04L49/111
Filed: 2001-09-06
Abstract: The invention allows to assess a level of multicast traffic in a data switch of the kind devised to steer fixed-size data packets, from input to output ports, through a shared memory which temporarily holds a single copy of them in buffers. Output ports are each equipped with an output port queue which contains pointers to those of the buffers holding data packets due to leave the data switch through them. Then, the invention assumes that the total number of shared-memory buffers currently holding a data packet is counted and compared to the total number of buffer pointers found in the output queues.  Hence, a metric of the level of multicast traffic is derived resulting in the calculation of a MultiCast Index (MCI). The invention further assumes that data switch is used together with a Switch Core Adaptation Layer (SCAL) which includes a multicast input queue. Because traffic is handled on the basis of a set of priority classes a multicast threshold MCT(P), associated to the multicast input queue, per priority, is set or updated. Therefore, while receiving incoming data traffic, MCI is kept calculated and, for each priority class (P), in each SCAL, MCI is compared to MCT(P) to determine whether corresponding multicast traffic must be held or not. The invention helps preventing traffic congestion in communications networks, using fixed-size data packet switches, that would otherwise occur when a high level of multicast and broadcast traffic has to be supported at network nodes.

Abstract: L'invention concerne une matrice osseuse déminéralisée (DBM) ou autre composition matricielle améliorée mélangée avec un agent stabilisant pour agir comme: 1) barrière de diffusion; 2) inhibiteur d'enzymes; 3) substrat compétitif; ou 4) fragment de masquage. Une barrière de diffusion agit comme une barrière pour empêcher la dégradation des facteurs ostéoinductifs présents dans la DBM par des enzymes protéolytiques ou glycolytiques au niveau du site d'implantation. Les agents stabilisants peuvent être n'importe quel matériau biodégradable, tel que des amidons, des amidons modifiés, de la cellulose, du dextrane, des polymères, des protéines, ou du collagène. A mesure que les agents stabilisants se dégradent ou se dissolvent <i>in vivo</i>, les facteurs ostéoinductifs, tels que TGF-.beta., BMP et IGF, sont activés ou exposés, et les facteurs activés travaillent à recruter des cellules de l'espace prévasculaire au site de la lésion et à causer la différenciation en cellules de formation osseuse. L'invention concerne en outre des méthodes de préparation, d'essai et d'utilisation des compositions matricielles ostéoinductives améliorées.
