摘要： A proximity sensor is provided with multiple channels and a proximity sensor chip (IC) connected to the multiple channels through a sensing line. The proximity sensor chip (IC) includes an internal temperature sensor, senses a first sensing value through the multiple channels, senses a second sensing value through the internal temperature sensor, and compensates the first sensing value through addition or subtraction of the second sensing value with respect to the first sensing value. The internal temperature sensor includes: a clock signal generator including a first oscillator and generating first clock signals variable according to temperature characteristics; and a temperature compensator generating second clock signals according to a setting condition corresponding to the first clock signals generated from the clock signal generator and outputting the second sensing value by counting the second clock signals through a second oscillator generating reference clock signals independent of temperature change.

摘要： The disclosure provides a method for identifying a modal frequency of a beam bridge by considering influence of environmental temperature. The method includes the following steps: installing a sensor on a newly-built beam bridge without damage, measuring a dynamic response of the beam bridge cinder ambient excitation, recording temperature data, processing by a modal parameter identification method to obtain a modal frequency value at the temperature, and starting from a modal frequency corresponding to the temperature, carrying out iterative calculation to obtain the modal frequency at any temperature. The modal frequency value at any temperature is obtained by arranging a small number of sensors and carrying out a small number of tests, so that the influence of the temperature on the modal frequency is quantified, furthermore, the part of environmental influence is eliminated in future damage evaluation of the beam bridge, which allows for a more accurate damage evaluation result.

摘要： A method for compensating for a temperature drift of an accelerometer for measuring the lateral tilt of a motorbike. When the vehicle is in the “bike upright” condition, and the temperature of the accelerometer is at least 30° C. above its reference temperature, a reading is taken of the acceleration values. These values are then processed in order to identify the coefficient of the slope of the straight line for correcting the offset of each axis of the accelerometer. A processing operation involves verifying the strict monotony of the coefficients in at least two successive readings and ensuring that the mean value thereof is included between determined limits. The mean coefficient that is finally obtained then can be used to correct the temperature of accelerations read over the entire operating range of the accelerometer. Thus, the computation of the tilt angle of the motorbike is more precise.

摘要： A position detection unit generates a position detection value PFB that indicates the position of a control target. A temperature detection unit generates a temperature detection value that indicates the temperature. A correction unit corrects the position detection value PFB. A controller generates a control instruction value SREF such that the position detection value PFB_CMP subjected to the correction matches a position instruction value PREF that indicates the target position of the control target. A driver unit applies a driving signal that corresponds to the control instruction value SREF to an actuator. The correction unit corrects the position detection value PFB such that the relation between the position detection value PFB and the actual position exhibits linearity that is uniform independent of the temperature.

摘要： The present disclosure relates to a computer-implemented method for determining at least one measurement uncertainty for at least one measured value of a field device, in which a set of calculation parameters is created that contains at least all standard parameters of a set of standard parameters in the form of a respectively corresponding calculation parameter, and the at least one measurement uncertainty and/or a measurement uncertainty budget is calculated and/or specified based upon at least one calculation parameter value of at least one calculation parameter. Each standard parameter of the set of standard parameters comprising at least one standard parameter represents an independent variable causing the measurement uncertainty. To each calculation parameter is assigned at least one calculation parameter value in the form of at least one standard parameter value, one device parameter value, and/or one application parameter value.
