Abstract: An anemometer and method for analyzing fluid flow is described. In one embodiment, a transistor sensor is heated by applying power to cause its base-emitter junction to rise from an ambient first temperature to a second temperature. The power is removed, and the Vbe is measured at intervals as the junction cools. The Vbe equates to a temperature of the junction. The temperature exponentially decreases, and the time constant of the decay corresponds to the fluid flow velocity. A best fit curve analysis is performed on the temperature decay curve, and the time constant of the exponential decay is derived by a data processor. A transfer function correlates the time constant to the fluid flow velocity. The transistor is thermally coupled to a metal rod heat sink extending from the package, and the characteristics of the rod are controlled to adjust the performance of the anemometer.

Abstract: A component of a well system can be tested by pressurizing the component of the well system a test pressure via two supply lines connected to the component of the well system, e.g. a choke line and a kill line. Then, a first of the two supply lines can be isolated from the second supply line and the component of the well system. The change in pressure can be measured in the first supply line and the change in pressure can be independently measured in the second supply line and the component of the well system. The change in pressure of the first supply line can be subtracted from the change in pressure of the second supply line and the component. Then, the change in pressure for the component can be analyzed to determine if the component of the well system is maintaining pressure integrity, i.e. leaking or not leaking.

Abstract: Method for the segmentation and classification of seismic or other geophysical data. Curves or surfaces are identified in the geophysical data (10), then pairs of the curves or surfaces (12) are matched up according to a selected measure of shape similarity (13) such as the Hausdorff distance between members of a pair. The matched curves or surfaces (15) are used to define geobodies or faults in the geophysical data volume (16).

Abstract: A detection circuit includes an amplifier circuit, a rechargeable unit, a first comparator, a second comparator, a reference voltage providing circuit, a first resistor R1, a second resistor R2, and a processing unit. The amplifier circuit is connected to a bridge circuit sensor and amplifies signals output by the bridge circuit sensor to an output voltage Vo. The reference voltage providing circuit provides a reference voltage Vref1. A charge current of the rechargeable unit is (Vref1?V0)/(R1+R2), and a discharge current is (Vref1?VCC)/R1. The processing unit controls the rechargeable unit to be charged for a time period T1 and to be discharged during a time period T2. The processing unit then calculates the output voltage Vo according to an equation: (Vref1?V0)×T1/(R1+R2)=(Vref1?VCC)×T2/R1, and obtains the signals according to the output voltage Vo.

Abstract: Self-tuned detection of memory leaks or other resource leaks is described. Sample size and sample rate are set manually or computationally selected. Self-tuning leak detection code uses one or more self-tuning mechanisms to exclude outlier sample points, to perform a second order linear regression, and/or to identify a derivative of a sequence of linear regression slopes. Statistical analysis computationally proactively determines what trend is present: upward, steady, or downward. Analysis may compare a linear regression slope to a threshold at which the slope realizes an upward trend, possibly only after crossing the threshold a specified number of times. Regression calculation may be optimized by setting an origin to the median of the time values and setting a scale to their constant time interval. A watchdog may use self-tuned detection to monitor processes, for efficiently recycling processes to prevent problems caused by resource loss.
