  • Patent number: 10725200
    Abstract: Borehole logging methods for estimating a parameter of interest using nuclear radiation. Methods include estimating a water saturation of the formation from gamma radiation from at least the formation detected in the borehole using a radiation detector, the gamma radiation responsive to a pulsed neutron source and resulting from at least one of: (i) decay of nitrogen-16 formed by activation of oxygen-16, and ii) inelastic scattering of neutrons from oxygen. This may include using at least one processor to: obtain a gamma ray count measurement, representing gamma rays from one of: (i) the decay of nitrogen-16 (ii) and the inelastic scattering, and estimate the water saturation using the gamma ray count measurement and a model comprising a relationship between measured gamma ray counts and modeled gamma ray counts from each of a fully water saturated formation and a minimally water saturated formation.

  • Patent number: 9048747
    Abstract: A startup circuit delivers regulated startup current to a control IC in a switched-mode power supply (SMPS) system, and automatically disconnects the startup current when the SMPS Control IC starts switching the transformer or inductor used as the energy storage element in the SMPS system. Disconnection of the startup current may be triggered by detecting a time-varying voltage waveform on an accessible node in the SMPS system, or by detecting an increased current consumption by the SMPS Control IC, without requiring any ground reference to the SMPS Control IC, nor without requiring any logic signals generated by the SMPS Control IC. This provides for rapid and predictable startup of an SMPS Control IC and reduced power loss once the SMPS Control IC is operational, and is independent of the operating voltages of the SMPS control IC, and independent of the particular control scheme and switch topology of the SMPS system.
