Patent CA-2403048-A1 (CA)
Title: Low power voltage regulator circuit for use in an integrated circuit device
Inventor: KUO HARRY H
IPC: H03K19/00
Filed: 2001-04-20
Abstract: A voltage regulator circuit (11) that receives an input signal (450) and provides an output signal (600) that is clamped at a specified voltage desired for an internal circuit. The disclosed voltage regulator circuit includes a plurality of subcircuits including a voltage tracking subcircuit (500) in which the output voltage tracks the input voltage with no voltage drop when the input voltage starts to rise from zero volts. In the input voltage increases to a desired voltage level for the internal circuit, the voltage tracking subcircuit (500) clamps the output voltage to remain at that voltage.  If the input voltage further increases to a higher voltage, the voltage tracking subcircuit (500) is disabled and one of a plurality of voltage maintaining subcircuits (550, 560, 570) takes control so that the output voltage remains at the desired voltage for the internal circuit.

Abstract: L'invention concerne une architecture distribuée permettant de rendre une capacité de stockage virtuelle dans un réseau de zone de stockage (SAN) et de gérer la mémoire physique et virtuelle. Un programme informatique de logiciel de virtualisation est composé de deux parties, à savoir la virtualisation et la traduction. Chaque partie réside dans une région différente. Les deux parties fonctionnent cependant de manière interactive. Un SAN couplant un ensemble d'hôtes (1) grâce à un commutateur de réseau (2) avec un ensemble de dispositifs de stockage (4) est pourvu d'un gestionnaire de virtualisation de stockage (SVM) (3). Le SVM commandant le logiciel informatique de virtualisation dirige la virtualisation de la capacité de stockage physique et la gestion de métadonnées. Le commutateur de réseau achemine les opérations E/S de stockage entre les hôtes et les dispositifs de stockage, alors que le logiciel de traduction est localisé dans un processeur, soit dans un hôte, soit ailleurs dans le SAN. Cependant, le commutateur de réseau et le SVM découplent les tâches en vue d'alléger la charge et de prévenir des embouteillages, la mise en oeuvre pratique permettant de concevoir le commutateur de réseau, le ou les processeur(s) commandant le programme de virtualisation et le SVM dans de nombreuses configurations allant de l'assemblage distribué à l'assemblage intégré. Le logiciel de virtualisation fournit également l'adaptation de la configuration en temps réel de changements se produisant dans la configuration de l'ensemble d'hôtes et du stockage de dispositifs du SAN.

Abstract: Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic media canisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic media and detected by the embedded probe in selected canisters. The canisters are provided in a plurality of stacks and are in fluid communication with a header disposed at the bottom of the vessel housing the various stacks of canisters. Solids that do not pass through the canisters are accumulated at the bottom of the vessel and easily drained through a drain port. The water will pass through the media and will be conveyed back to the ocean water without contamination . At some point in time, the organophilic media will become "spent" and at a certain "spent level", the saturated condition of the organomedia will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the "spent"  organophilic media should be replaced with fresh media or the spent media regenerated.

Title: Gas-lock re-prime device for submersible pumps
Inventor: GAY FARRAL D
IPC: E21B43/12
Filed: 2003-04-11
Abstract: A submersible pump assembly has a pump and a valve connected to the outlet of the pump. An outlet of the valve is connected to a riser. A valve member in the valve housing is vertically movable between a pumping position and a priming position, the valve member being biased toward the priming position. A priming conduit connects the outlet of the valve housing to the inlet of the pump for directing well fluids flowing through the conduit into an intake of the pump for re-priming the pump. When the pump is pumping well fluid, the valve member is moved to the pumping position by the fluid pressure, well fluids flowing from the inlet of the valve housing to the outlet of the valve housing but not through the priming conduit. When pumping ceases, the valve member returns to the priming position, well fluids flowing through the priming conduit for re-priming the pump.
