20150371836 | SATURATION CORRECTION FOR ION SIGNALS IN TIME-OF-FLIGHT MASS SPECTROMETERS - The invention relates to time-of-flight mass spectrometers in which individual time-of-flight spectra are measured by detection systems with limited dynamic measurement range and are summed to sum spectra. The invention proposes a method to increase the dynamic range of measurement of the spectrum. To achieve this, those ion signals whose measured values display saturation of the analog-to-digital converter (ADC) are replaced by correction values, particularly if several successive measured values are in saturation. The correction values are obtained from the width of the signals, preferably simply from the number of measured values in saturation. | 12-24-2015 |
20160041013 | METHOD OF POWER-SAVING IN MEMS SENSOR APPLICATIONS - Method including detecting low user dynamics by a first MEMS sensor is provided. A first sensor determines sampling rate value corresponding to the low user dynamics. The first sensor sampling rate value is less than a second sensor sampling rate value corresponding to high user dynamics. A sampling rate of a second MEMS sensor is adjusted to the first sensor sampling rate value. | 02-11-2016 |
20160061627 | SENSOR OFFSET CALIBRATION USING MAP INFORMATION - Systems, processes, and techniques for calibrating an onboard sensor of a vehicle are presented here. The vehicle has a control system that is capable of performing at least some of the tasks related to the calibration procedure. An exemplary methodology collects vehicle status data and obtains navigation map data during operation of the vehicle. A current calibration factor is calculated for the onboard sensor, based on the collected vehicle status data and the obtained navigation map data. More specifically, the vehicle status and navigation map data can be used to determine when the current conditions are suitable for performing calibration. When the current conditions are satisfactory, the calibration factor is calculated. Thereafter, the onboard sensor can be calibrated in response to the current calibration factor. | 03-03-2016 |
20160126969 | IMPROVED METHOD OF SIGNAL PROCESSING AND SYSTEM INCLUDING THE SAME - A method of measuring signal change including performing at least one calculation or iteration step based on one or more chaos non-linear dynamical functions on first and second input signals, or sample of signals, to produce iteration values. Performing at least a second iteration step by repeating the at least one calculation or iteration step based on one or more non-linear dynamical functions on the first iteration values to produce a second iteration values and subtracting one set of iteration values generated from either the first or second input signal from the corresponding iteration values generated from the other input signal. | 05-05-2016 |
