Abstract: L'invention est une interface universelle pour système d'archivage de serveur multimédia qui sert à augmenter le débit des chaînes de données en évitant les duplications de données et les changements de contexte. Le système d'archivage de l'invention comprend un service d'enregistrement d'exportations qui fournit des indicateurs de fonction en cas d'implantation d'ensembles prédéfinis d'interfaces d'opérations sans duplication. Ces interfaces comprennent un service d'initialisation servant à établir les structures de données nécessaires et à apposer des comptes d'utilisations aux objets pour éviter que ceux-ci ne soient enlevés durant les opérations sans duplication. Les interfaces d'opérations sans duplication sont dotées d'un service de terminaison qui nettoie les structures de données et supprime les comptes d'utilisations. D'autres services indiquent quels sont les fichiers appropriés pour les opérations sans duplication et localisent et enregistrent les attributs de fichiers nécessaires afin d'effectuer ultérieurement une saisie des tampons au niveau d'interruption. Une structure de données est établie pour conserver ces attributs. Un autre service bloque un tampon à un niveau d'interruption, restitue les données présentes et établit l'adressabilité au tampon dans un autre espace d'adresses. Une structure de données conserve ces attributs de tampon. Un autre service débloque le tampon au niveau d'interruption. Finalement, un dernier service fournit à la configuration d'accès du fichier des informations sur les changements comme ceux qui seraient nécessaires pour prendre en charge les fonctions d'un magnétoscope. Une chaîne de hachage utilisant une liste à liaison unique mise à jour atomiquement permet de consulter les tampons avec sûreté au niveau d'interruption. Ceci est facilité par le verrouillage des opération de comparaison et d'échange. Une interface de boîte postale est utilisée au niveau d'interruption pour effectuer des préextractions et transmettre les informations au démon. En cas de collision de verrouillage ou quand le tampon n'est pas disponible, la saisie du tampon se fait dans un contexte de processus.

Abstract: A device for eliminating coherent pickup error in a fiber optic gyroscope. The polarity of the drive signal to the phase modulator of the gyroscope is switched periodically. The scale factor consequently changes.  The phase and amplitude of coherent pickup error generated in the gyroscope circuits do not change during the switching. Therefore, nearly all of the coherent pickup error is substracted out of the gyroscope signal during the digital signal processing of the signal.

IPC: G05B19/408
Filed: 1997-06-03
Granted: 2005-10-18
Abstract: Large machines, especially those having working envelopes in excess of fifteen feet, exhibit unacceptable errors because of thermal expansion and mechanical misalignments between the axes. The errors have traditionally been minimized by enclosing the machine in a thermal enclosure, by careful calibration, or by mounting a laser interferometer on each axis. These solutions are costly, may require frequent recalibration, and do not correct for small rotations of one axis relative to another axis due to wear etc. The present invention uses an interferometric laser tracker or a comparable 3D position sensor to measure the position of a retroflector attached to the end effector, e.g. a machine head when the machine comes to rest. A computer compares the measured position to the desired position according to the machine media, and adds the appropriate correction with trickle feed media statements to move the machine to the correct position prior to further machining.

IPC: A61M16/00

Granted: 2005-11-29
Abstract: Methods and apparatus for determining leak and respiratory airflow are disclosed. A pressure sensor (34) and a differential pressure sensor (32) have connection with a pneumotach (24) to derive instantaneous mask pressure and airflow respectively. A microcontroller (38) estimates a non-linear conductance of any leak path occuring at a mask (12) as being the low pass filtered instantaneous airflow divided by the low pass filtered square root of the instantaneous pressure. The instantaneous leak flow is then the conductance multiplied by the square root of the instantaneous pressure, and the respiratory airflow is calculate d as being the instantaneous airflow minus the instantaneous leak flow. The time constants for the low pass filtering performed by the microcontroller (38) can be dynamically adjusted dependent upon sudden changes in the instananeous leak flow.

Abstract: A plastic bag comprises first and second opposing panels, a reclosable zippe r (22), and a sider (32). The first and second opposing panels (12,14) are fixedly connected to each other along a pair of sides (16 ) and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth (10) formed opposite the bottom. The zipper (22) includes a first track with a first profile (24) and a second track with a second profile (28). The first and second profiles are releasably engageable to each other. The slider (32) is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles (24, 28) are engaged to each other while the slider (32) is in the closed position, and the first and second profiles (24,28) are disengaged from each other in response to movement of the slider from the closed position to the open position. To prevent the slider (32) from going past the ends of the zipper and to provide adequate ends strength that resists stresses applied to the profiles during normal use of the bag, end stops (36) in the form of flexible segments severed from a flexible plastic strip, fairly rigid segments severed from an extruded clip profile, or softened plastic material, are applied and secured to opposite ends of the zipper.

Title: Method and apparatus for mitigating intermodulation effects in multiple-signal transmission systems
Inventor: DENT PAUL W
IPC: H04J1/06
Filed: 1997-09-30
Granted: 2007-08-14
Abstract: Method and apparatus for mitigating intermodulation distortion effects in frequency division multiple access (FDMA) communications systems. In one embodiment, an effective transmit power level is determined for each communication signal to be transmitted, and signals are allocated to frequency channels such that a smooth tapering or transmit power levels across contiguous frequency channels is achieved. Such smooth power tapering across frequency channels minimizes the possibility that two high power signals will generate an intermodulation distortion product sufficient to disrupt transmission of an immediately adjacent low power signal. In another exemplary embodiment, communication signals are allocated such that high power signals are positioned near a frequency band center, while low power signals are positioned near frequency band edges. As a result, intermodulation distortion between frequency bands in a multiple-band communication system is also minimized.
