Title: Method and apparatus for providing telephony services by switch-based processing of media streams
Inventor: CARROLL MARTIN D
IPC: H04M3/56
Filed: 2001-03-02
Abstract: Telephony services are implemented using a media-control framework in which a media switch controls the mixing of multiple participant streams. A connection is established between the media switch and each of the participants in a given call or other communication. The media switch then implements a desired telephony service by controlling the mixing of media streams in accordance with multiple permit sets and multiple want sets, each of the permit sets and each of the want sets being associated with a given media stream of a given participant. A particular one of the permit sets specifies one or more additional participants that are permitted to receive a send flow of the given stream in conjunction with the telephony service, while the corresponding one of the want sets specifies one or more additional participants from which the given participant wants to receive a receive flow of the given stream in conjunction with the telephony service. The media switch utilizes the permit sets and the want sets to generate onto each receive flow for the one or more media streams the mix of all the send flows for the one or more media streams that satisfy the specified permissions and wants. The media switch may be implemented in a nondistributed manner, or in a distributed manner with a switch controller and one or more mixers.

Patent CA-2345718-A1 (CA)
Inventor: SMITH JACK W
IPC: G10L25/90
Filed: 1999-10-29
Abstract: La présente invention concerne trois méthodes qui permettent de déduire rapidement la fréquence fondamentale d'une forme d'onde ou signal complexe. Une méthode met en oeuvre les relations entre et parmi les fréquences harmoniques plus élevées comprenant des rapports de fréquence, des variations de fréquences, des proportions de variation de fréquence, et des relations découlant du fait que des fréquences harmoniques sont modélisées par des fonctions d'une variable entière dont les valeurs représentent des numéros d'harmonique. Une autre méthode définit les relations prédites/modélisées des harmoniques de registres de fréquence choisis à des échelles logarithmiques, enregistre les fréquences de partiels détectés à des échelles similaires, et déplace les échelles l'une relativement à l'autre pour rechercher une correspondance de trois harmoniques. Une fois cette correspondance établie, des numéros d'harmonique possibles et la fréquence fondamentale implicite peuvent être extraits directement. Si les partiels détectés correspondent à plus d'une série de relations harmoniques prédites/modélisées, des algorithmes de la première méthode sont mis en oeuvre pour choisir le fondamental déduit. Dans une troisième méthode, des fréquences harmoniques pour une pluralité de fondamentaux sont accumulées et organisées afin que des partiels liés à un fondamental inconnu puissent être comparés avec elles en vue de déduire le fondamental inconnu.

Title: Perceptual weighting device and method for efficient coding of wideband signals
Inventor: LEFEBVRE ROCH
IPC: H04Q7/22
Filed: 1999-10-27
Abstract: A perceptual weighting device for producing a perceptually weighted signal in response to a wideband signal comprises a signal preemphasis filter, a synthesis filter claculator, and a perceptual weighting filter. The signal preemphasis filter enhances high frequency content of the wideband signal to thereby produce a preemphasised signal. The signal preemphasis filter has a transfer function of the form: p(z)-1 - µz-1 wherein µ is a preemphasis factor having a value located between 0 and 1. The synthesis filter calculator is responsive to the preemphasised signal for producing synthesis filter coefficients. Finally, the perceptual weighting filter processes the preemphasised signal in relation to the synthesis filter coefficients to produce the perceptually weighted signal. The perceptual weighting filter has a transfer function, with fixed denominator, of the form: W(z) A (z/.gamma.1) / (1-.gamma.2z-1) where 0 < .gamma.2 < .gamma.1 <= and .gamma.1 and .gamma.2 are weighting control values, whereby weighting of the wideband signal in a format region is substantially decoupled from a spectral tilt of this wideband signal.

IPC: B29D17/00
Filed: 1999-11-06
Abstract: According to the inventive method for determining the thickness of at least one layer provided on a substrate, the measurement can be constructed simply  and reliably and a reliable measuring result can be obtained by measuring reflection- and/or transmission light intensity values of zero order in dependence on the wavelength and calculating said reflection- and/or transmission light intensity values using an iteration model which is dependent on the individual layer parameters. The layer parameters are alter ed in order to introduce a consistency between the measured values and the calculated values and the substrates have geometrical structures whose geometrical dimensions are used as further parameters of the iteration model . The inventive method also provides a means of determining the geometry of structures in the substrate, for example the depth, width and the repetition  interval of grooves in a blank for geometrical storage media, such as CDs.</ SDOAB>

Title: Filter monitoring system using a thermistor
Inventor: SHERWOOD ROBERT A
IPC: B01D46/46
Filed: 2001-01-12
Abstract: A system (figure 3) for monitoring a percentage of filter life remaining of a filter assembly (18) of filter-fan devices.   The system uses a single thermistor (RT1) that is operated in two separate modes for monitoring the filter assembly. The thermistor (RT1) is positioned in the airflow of the filter-fan device (2) adjacent to the air outlet. A first current is applied to the thermistor (RT1) for determining the temperature of the airflow from a first thermistor voltage. The first thermistor voltage is responsive to the first current applied to the thermistor. A second current that is greater than the first current is applied to heat the thermistor. The temperature of the thermistor is determined from the second thermistor voltage which is responsive to the second current applied to the thermistor. The percentage of filter life remaining of the filter assembly is determined from the temperature of the airflow and the second thermistor voltage.
