Title: Procede et appareil permettant de reduire le temps de verrouillage d'une boucle a asservissement de phase
Inventor: GALLARDO KEITH
IPC: H03L7/187
Filed: 2001-05-08
Abstract: L'invention concerne un procédé et un appareil permettant de réduire le temps de verrouillage dans un synthétiseur de fréquence à boucle à asservissement de phase possédant un mode actif et un mode veille. En mode actif, le synthétiseur de fréquence sert à maintenir une sortie en fréquence stable. Le mode veille ou sommeil sert à réduire la consommation lorsque le synthétiseur de fréquence n'a pas à fournir de sortie en fréquence. Lorsque le synthétiseur fonctionne en mode veille, la valeur la plus récente de la tension de syntonisation de l'oscillateur commandé en tension (VCO) est maintenue sur la ligne témoin de syntonisation de l'oscillateur VCO du synthétiseur de fréquence. Dans les synthétiseurs de fréquence à circuit intégré, la tension est maintenue au niveau de la fiche de sortie permettant la syntonisation de l'oscillateur VCO. L'erreur de tension au niveau de la fiche de syntonisation du VCO est ainsi minimisée, ce qui permet de minimiser le temps d'asservissement du synthétiseur de fréquence.

Inventor: BASSETT LONNIE
IPC: E21B47/00
Filed: 2001-10-22
Abstract: The present invention generally provides a closed feedback system for operating peripheral devices in response to environmental conditions.  Illustrative environmental conditions include well bore pressure, line pressure, fluid levels, flow rates and the like. In one embodiment, a flow controller (170) disposed in a fluid line (155) is operated in response to operating variable readings (e.g., pressure and/or flow rate) taken in the flow line and/or a well bore. The variable measurements are then compared to target values. If necessary, the flow controller is closed or opened to control the rate of fluid flow through the flow line and thereby achieve the desired target values. In another embodiment, the operation of a pump motor (135) is monitored. Operating variables, such as voltage, current and load, are measured and compared to target values. In the event of a difference between the actual values of the variables and the target values, the flow controller is adjusted to affect the head pressure on a pump being driven by the motor. In some cases, the motor operation may be halted or otherwise adjusted.
