Abstract: A test and measurement Instrument samples an input digital logic signal to produce logic samples, compresses the logic samples into compression codes, and stores the compression codes into acquisition memory. Compression includes parsing the logic samples into groups and assigning compression codes to those groups, and is performed so as not to lose information about the input digital logic signal's activity. The instrument converts the stored compression codes into a waveform image in display memory and displays the stored waveform image on a display device.

Abstract: Methods and apparatus are provided for determining the content of a first element in a formation which cannot otherwise be determined via a capture spectrum measurement. The methods and apparatus utilize the inelastic spectrum measurement of the first element and the inelastic and capture spectrum measurements of at least a second element. The methods and apparatus have particular application to determining the carbon content of a formation although they are not limited thereto. The inelastic and capture spectrum measurements of silicon are useful in making such determinations, although other chemical elements may be used as the second element.

Abstract: A calibration method in which secular change in sensor output values obtained at calibration times is estimated and the next calibration date can be determined at an appropriate interval and a zirconia-type oxygen analyzer using the above calibration method is achieved. The present invention is characterized by the fact that, in a calibration method in which a standard sample having a known value is measured and the output value of a measuring instrument corresponding to a sensor output value at the time of measurement is calibrated, the sensor output value obtained in implemented calibrating operations is stored in succession as the data for calibration history and the state of secular change in said sensor output value is estimated based on the stored past data for calibration history to determine the next calibration date.

Abstract: The installation of an electrical cable in a building and its subsequent testing are managed by first creating a computer database indicating the type of cable, the location where the cable is to be installed, the performance standard it should meet when installed in that location, and a test regimen to verify compliance with the performance standard. The database is then transferred into a hand held portable test instrument which is placed at the building site and connected to the cable to be tested.

Abstract: A gantry to be used in the construction process of bridges, viaducts and other structures, which is equipped with a system that automatically adjusts the prestressing of the gantry's structure in accordance to the external actions being applied on it when loadings occur. The adjustment of the prestressing is achieved through the use of at least one sensor (2) that monitors the structure and which sends the measurements taken to a controller (6), . This controller is then capable of activating at least one actuator which alters the tension of the structure's prestressing cable or cables. Amongst the many advantages of the present invention, one is the possibility of applying a large amount of prestressing without this implying undesirable deformations in the main structure (1) when exterior loads are not applied.

Abstract: A method is disclosed wherein a plurality of sensors mounted on a structure, a baseline data set for each of the plurality of sensors and a calibration procedure verify the integrity of a structural health management system. Initially a baseline data set is established. Before performing the structural health assessment a calibration-in data set for each of the plurality of sensors is collected. The calibration-in data set is compared to the baseline data set for each sensor of the plurality of sensors. If the calibration-in data set and the baseline data set match then a structure characterization is performed. If the calibration-in data set and the baseline data set do not match, a calibration-out procedure is performed to generate a calibration-out data set. If the calibration-out data set and the calibration-in data sets match, then a determination is made that the structural health management system was working.

Abstract: An apparatus and method for measuring a flow velocity profile of fluid traveling in a pipe or conduit uses an ultrasonic wave transmitted from an ultrasonic wave transducer mounted at an angle on the outside of a pipe using a wedge, and made incident onto the fluid in the pipe to measure the fluid flow velocity profile, using the principle that a frequency of an ultrasonic wave, reflected by a reflector existing in the fluid, is changed depending on a flow velocity due to Doppler effect. The transmission frequency and the angle of incidence onto the pipe can be selected to suppress frequency dependence of a measured value due to Lamb wave and allow the flow velocity or flow rate of fluid to be measured with a greater accuracy.

Abstract: A detection method of reducing the air pressure of tires based on the rotational speed of wheels mounted on a vehicle. The method includes steps of: determining the rotational speed of each wheel, memorizing the rotational speed of each wheel, determining the loading sensitivity of the dynamic load radius of tires caused by movement of a load during turning, comparing said loading sensitivity with the loading sensitivity of the dynamic load radii of tires at initialization which are preliminarily memorized, and judging decompression of tires based on the result of the comparison. Further, a loading sensitivity-calculating method of determining the loading sensitivity of the dynamic load radii of tires includes steps of: determining a lateral acceleration during turning of a vehicle, determining the shift rate of a judgment value which is the relative comparison of rotational speed of wheels on a pair of diagonals of a vehicle, and determining the loading sensitivity.

Abstract: Robust methods are developed to provide bounds and probability distributions for the locations of objects as well as for associated variables that affect the accuracy of the location such as the positions of stations, the measurements, and errors in the speed of signal propagation. Realistic prior probability distributions of pertinent variables are permitted for the locations of stations, the speed of signal propagation, and errors in measurements. Bounds and probability distributions can be obtained without making any assumption of linearity. The sequential methods used for location are applicable in other applications in which a function of the probability distribution is desired for variables that are related to measurements.

Abstract: Systems and methods for correcting measurements of fluid flow using device-specific information to compensate for differences between individual devices of the same design. In one embodiment, a method includes providing device-specific calibration data; sensing a fluid flow; computing a measured fluid flow based on the sensed fluid flow, and correcting the measured fluid flow based on the device-specific calibration data. More particularly, the fluid flow measurement is corrected using correction factors that compensate for the use of a gas that is different from the calibration gas (CF0 (1+aF+bF2+cF3)), for device variations in sensor sensitivity (1+??R), and for variations in the split flow of fluid through the flow meter (1???ADC(Sp/100)2). The sensor and split flow correction factors may be used independently of each other in some embodiments.

Abstract: A two-axis fluxgate sensor has a driving pulse generating circuit which generates pulse signal and outputs as a driving signal, and X-axis and Y-axis fluxgates which are in proportional relation with each other. The two-axis fluxgate sensor generates voltage values of X-axis and Y-axis fluxgates corresponding to the magnetism which is generated from the driving signal, and a memory stores therein a neural network weight matrix. When the voltage values of the X-axis and Y-axis fluxgates are measured, a control unit compensates for the voltage values by using the neural network weight matrix which is stored in the memory, and computes an azimuth angle by using the compensated voltage values. An accurate azimuth angle can be obtained even at slopes.
