    摘要: An improved reference current generator for use in an integrated circuit. A voltage difference generator generates two voltages that are separated by a relatively small electrical potential. The two closely separated voltages are applied across a resistive element with relatively large impedance value resulting in a small and stable reference current. The stable reference current is mirrored and, if desired, amplified for use on the integrated circuit. A driver selectively drives state information off chip for assisting in post-silicon correction of unwanted sensitivities. A configuration memory stores values used to adjust effective device widths and lengths for correcting unwanted sensitivities.

    摘要: A system and method for determining fluid distribution in subterranean reservoirs including determining a water saturation in macroporosity from the capillary pressure data representative of the macroporosity using a saturation height function, correcting capillary pressure data representative of microporosity to have an entry pore value equivalent to a pore size defining the microporosity, determining a water saturation in the microporosity from the corrected capillary pressure data representative of the microporosity, and using the macroporosity water saturation and the microporosity water saturation to estimate fluid distribution within the subterranean reservoir. The system and method may also include the estimation of hydrocarbon reserves.

    摘要: Methods and devices for providing temporary placement of a filter in a blood vessel are disclosed. A filter delivery system in accordance with one exemplary embodiment of the present invention includes a catheter having an elongate shaft and a tubular member disposed within a shaft lumen defined by the elongate shaft. The elongate shaft also includes a proximal end, a distal end, and a wall defining the shaft lumen. The tubular member has a first end fixed to the wall of the elongate shaft, and a second end disposed within the shaft lumen. The tubular member defines a guidewire lumen that is in fluid communication with a distal guidewire port defined by the second end of the tubular member. The catheter also includes a proximal guidewire port extending through the wall of the elongate shaft. A filter may be disposed within a distal portion of the shaft lumen. A distal end of a guidewire is fixed to the filter. The guidewire preferably extends through the distal guidewire port, the guidewire lumen, and the proximal guidewire port.
