20090082985 | METHOD OF CALIBRATING TEMPERATURE COMPENSATED SENSORS - A method of calibrating an individual sensor of a particular sensor type whose output varies non-linearly with at least one measured quantity and at least one operating condition, comprises producing a set of calibration curves for each of a number of sample sensors of the particular sensor type, each curve showing the variation of the sample sensor output with the at least one measured quantity at a different value of the operating condition for the particular sensor type of said individual sensor, said set of curves covering the required operating range for the particular sensor type. The resulting sets of calibration curves of the plurality of sensors derived are then averages and the results used to produce a generic calibration surface for the particular sensor type showing the variation of the sensor reading with the at least one measured quantity across the required operating range. Individual calibration measurements are then taken for a number of different values of the measured quantity for the individual sensor at just a small number of discrete values for the at least one operating condition which fall within the full range of operating values for the at least one operating condition for which the sensor is to be calibrated. The individual calibration readings are then used to map the generic calibration surface to the individual calibration measurements of the individual sensor in order to fit it to the individual sensor. | 03-26-2009 |

20120265471 | METHOD FOR RELIABLY OPERATING A SENSOR - A method is presented for reliably operating at least one sensor connected to a central control unit. Each sensor senses a sensor value for its sensor parameter and creates an interrupt to the control unit when its sensor value is outside a sensor value range limited by an upper and a lower threshold. Upon generation of an interrupt by a sensor, a modified sensor value range is calculated so that the sensor value causing the interrupt lies within the modified sensor value range, and the modified sensor value range is applied to the respective sensor. The method further includes repeatedly verifying correct behavior of each sensor. A computer-readable medium, a computer program product, and a system for executing the above-summarized method are also presented. | 10-18-2012 |
20130030746 | Calibration Method - A method of calibrating a measurement device, during which at least one given value of a quantity to be measured by the device is provided by a corresponding reference or standard. The indicated measurement indications and the corresponding given values of the measured quantity are recorded, at least one predefined characteristic property of at least one of the measurement indications is determined and compared to corresponding threshold range.

20130211762 | SELF-TUNING STATISTICAL RESOURCE LEAK DETECTION - 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. | 08-15-2013 |
