Abstract: A self-releasing clutch assembly for locking a vehicle door lock. The clutch assembly (11) includes a servo-actuated input drive and a cinching output drive. A gear shaped first actuator (42) is mounted to the input drive. A cylindrical second actuator (44) is mounted to the output drive and is moveable relative to the first actuator. Four pairs of rollers (50) are interdisposed between the first and second actuators and moveable between a disengaged position and an engaged position.  With the disengaged position, the rollers rest against the first actuator and allowing the second actuator to rotate relative thereto.  With the engaged position, the rollers interlock the first and second actuators for relative concurrent movement. The clutch assembly is characterized by the first actuator including four driving surfaces (43) and the second actuator including four corresponding abutments (48). The driving surfaces engage and move the rollers from the disengaged position to the engaged position in response to movement by the input drive.  The abutments then lock the rollers between the first and second actuators to couple the input drive with the output drive thereby transferring the movement of the input drive to the output drive.  The subject invention also includes a biasing device (54) for automatically returning the rollers to the disengaged position when the driving force from the first actuator ceases.

Abstract: Ce système s'articulant sur un agent aide un utilisateur individuel à la préparation d'une réunion à venir en l'assistant dans l'extraction des informations relatives à cette réunion et ce, à partir de diverses sources, d'après une information existant déjà dans le système. Ce système tire d'un programme agenda, contenant la date de la réunion, un texte d'entrée sous forme de caractères indicatif d'une réunion ciblée. Lorsque la date de la réunion approche, le système demande au programme agenda de fournir le texte relatif à l'événement ciblé et utilise cette information comme entrée pour le système agent, lequel analyse alors le texte d'entrée pour en extraire les différents composants, notamment le titre, le corps de texte, les participants, le lieu, le moment, etc. Le système établit également un modèle de filtrage servant à l'identification de domaines particuliers de réunion dans le texte relatif à la réunion. Cette information est utilisée aux fins de la demande de diverses sources d'information sur le web et de l'obtention de données pertinentes relatives à la réunion en cours à renvoyer au système d'ordonnancement d'agenda. Par exemple, si une personne doit assister à un débat avec Netscape ou Microsoft, le système se procure cette information de départ auprès du système d'ordonnancement d'agenda. Il analyse ensuite le texte pour prendre connaissance du fait que la réunion est <=Netscape >= et <= Microsoft >= et que le thème est <= débats >=. Il navigue alors sur le web à la recherche d'une information pertinente relative à ce thème. De la sorte, conformément à l'un des objectifs de cette invention, le système actualise le système d'ordonnancement d'agenda et, si besoin est, l'utilisateur en lui fournissant la meilleure information qu'il a pu recueillir aux fins de la préparation de la réunion ciblée. Dans un mode de réalisation préférée, l'information est mémorisée dans un fichier obtenu par sélection d'un lien contenu dans le système agenda.

Patent CA-2358382-C (CA)
Title: Channel identification in communications networks
Inventor: JIN DONGXING
IPC: H04B10/07
Filed: 2001-10-05
Granted: 2008-09-09
Abstract: Channels in an optical WDM network are each identified by at least two dither tones with which the channel is modulated, the dither tones alternating with a predetermined periodicity so that at any instant each channel is modulated by only one dither tone.    The dither tones are continuously generated at precise frequencies. Channel detection by detecting the dither tones, for channels having optical powers over a wide dynamic range, makes use of an FFT process which can detect dither tones for high power channels in a single operation. Coherent averaging of FFT results over time is used to detect dither tones for low power channels over multiple FFT operations.

Granted: 2010-01-26
Abstract: In a conveyor system a magnet element row aligned at least partly parallel to the conveyor path is arranged in a driving region to serve as a stationary drive means and conveyor elements comprise conducting parts (4) and are movable along the conveyor path through the drive region. The magnet element row (11) which for example consists of alternatingly orientated permanent magnets produces a magnetic field locally changing along the row (11). The conducting parts (4) are arranged on the conveyor elements (2) such that in the drive region they are positioned in the effective range of the magnet element row (11). A relative movement between the magnetic element row (11) and the conveyor element (2) produces eddy currents in the conducting parts (4) effecting forces counteracting the relative movement. The relative movement is for example produced by annular magnet element rows (11) which are revolvingly driven and of which a part moves parallel to the conveyor path being in interaction with the conducting parts (4) of conveyor elements (2). The drive means works without contact and permits jolt-free conveyance in particular when applied in connection with conveyor elements being moved along the conveyor path independently of one another and with varying speeds.

Title: Sensitivity of iterative spectrally smooth temperature/emissivity separation to instrument noise
Inventor: MUSE ARCHIE H
IPC: G01J5/00
Filed: 2001-07-27
Granted: 2010-02-02
Abstract: A method for estimating the error statistic for retrieved temperature and emissivity of a surface material includes determining the second order analytical error propagation from a measured radiance that differs from the true radiance by additive gaussian noise, which is independent in each band.  The radiance error is translated into a diagonal covariance matrix and an analytical estimate results in a determination of the standard deviation and bias of surface temperature. Further, the method for estimating the error statistic utilizes Monte Carlo simulation from a sufficiently large ensemble of radiance spectra for the retrieved surface temperature and emissivity.  Temperature and emissivity of the surface material were retrieved using ISSTES  algorithm.
