Abstract: Provided is a charged particle beam device wherein a secondary signal generated from an alignment pattern having known coordinate values in a sample coordinate system is detected, and a positional deviation quantity between the coordinate system of a sample (10) and the coordinate system of a stage (21) is calculated so as to generate coordinate correction data. At the time of observing a sample image, the secondary signal generated from the alignment pattern is detected at least once so as to perform realignment, and the coordinate correction data is updated. Thus, the charged particle beam device performs long-time inspection at a high observation magnification by accurately correcting the sample coordinate information obtained by temperature change, while suppressing device cost increase and throughput deterioration.

Abstract: Systems, methods, and devices are provided to determine an accurate neutron-gamma density (NGD) measurement for a broad range of formations, including low-hydrogen-index or low-porosity formations and formations with heavy elements. For example, such an NGD measurement may be obtained by emitting neutrons into a formation such that some of the neutrons inelastically scatter off elements of the formation and generate inelastic gamma rays. The neutrons and inelastic gamma rays that return to the downhole tool may be detected. Some characteristics of certain formations are believed to affect the fast neutron transport of the formations. Thus, if a formation has one or more of such characteristics, a correction may be applied to the count rate of neutrons, the count rate of inelastic gamma rays, or the neutron transport correction function, upon which the neutron-gamma density (NGD) may be determined.

Abstract: An apparatus and method is provided for monitoring a condition of a structure using a passive wireless antenna sensor having a known resonant frequency when mounted on the structure. A series of radio frequency signals are transmitted with sweeping frequencies around the known resonant frequency to the passive wireless antenna sensor. The passive wireless antenna sensor includes a dielectric substrate disposed between an antenna pattern and a ground plane such that a change in the condition of the structure will cause a change in one or more characteristics of the passive wireless sensor. A signal is received from the passive wireless antenna sensor and a resonant frequency of the passive wireless antenna sensor is determined based on the received signal. The determined resonant frequency is then compared to the known resonant frequency, whereby a change in the resonant frequency indicates a change in the condition of the structure.

Abstract: Thread parameters for a threaded object are determined. Spatial reference systems (X, Y, Z) and (X?, Y?, Z?) are respectively identified for a position sensor and the threaded object. A transformation matrix describing a quadratic form representing the threaded object in (X, Y, Z) may be determined to relate the reference systems. For example, a sensor trajectory on the threaded object may be determined, along with measurement points on the threaded object. The measurement points may be selected so the matrix, evaluated on these values, has maximum rank. Position data at measurement points in the second reference system may be transformed into the first reference system, yielding first results. After coating the threaded object, position data at the measurement points may be acquired again and transformed into the first reference system, yielding second results. Comparisons between the first and second results may provide thickness of the coating and quality verification.

The method includes determining a flux bulk temperature from the determined heat flux and determining a flux interface temperature from the determined heat flux. The flux interface temperature is the temperature at the friction interface during the slipping event. The method calculates a delta interface temperature by subtracting the flux interface temperature from the flux bulk temperature. The method executes a control action with the calculated delta interface temperature.

Abstract: A device and a method for aiding inflation for a vehicle involves obtaining access to vehicle tire pressure and temperature data, and utilizing an under-inflation detection module and an inflation condition testing module, thus making it possible to carry out a test for detecting a possible optimal inflation condition if the following criteria are met:—there is a non-critical under-inflation state for at least one of the vehicle tires;—the tires are not in an overheated state;—and the tire state is unchanged by sunlight. When the test module determines the optimal inflation condition, a signal is outputted. Such a method causes tire inflation to be carried out under favorable conditions actually corresponding to the reference value provided by the manufacturers.

Abstract: A bias value associated with a sensor, e.g., a time-varying, non-zero value which is output from a sensor when it is motionless, is estimated using a ZRO-tracking filter which is a combination of a moving-average filter and a Kalman filter having at least one constraint enforced against at least one operating parameter of the Kalman filter. It achieves faster convergence on an estimated bias value and produces less estimate error after convergence. A resultant bias estimate may then be used to compensate the biased output of the sensor in, e.g., a 3D pointing device.
