  • Patent number: 10900779
    Abstract: A method for the rapid detection of the linear axis angular error of an NC machine tool, belongs to the technical field of NC machine tool testing. Firstly, the measuring device is mounted on the linear axis. Then, the linear axis moves at three different speeds at a constant speed, and the upper measurement system automatically performs multi-channel acquisition and storage of the motion measurement's point measurement data. Then, based on the same geometric error signal, it is decomposed into the different frequency components, and the measurement angle error is filtered at the different speeds. Finally, the measurement angle errors at the three speeds after filtering are superimposed to complete the rapid measurement of the linear axis angular error of the machine tool. The measurement efficiency is high and data processing capability is strong.

  • Patent number: 10829698
    Abstract: A process for reducing pressure of a vapor stream used for reducing a temperature or pressure in a reactor. A pressure of a vapor stream is reduced with a turbine to provide a lower pressure vapor stream. The vapor stream rotates a turbine wheel within the turbine. The turbine wheel is configured to transmit rotational movement to an electrical generator. Thus, electricity is generated with the turbine. The lower pressure vapor stream is injected into a reactor and reduces a temperature in the reactor or reduces a partial pressure of a hydrocarbon vapor in the reactor.

  • Patent number: 8577641
    Abstract: An improved method for calibration of dynamic motion sensors. In one aspect, the method comprises sending a low frequency driving signal to an exciter to generate a harmonic movement in a shaker table, using an optical position sensor to produce an output representative of position, computing the acceleration of the shaker table and a dynamic motion sensor under test (SUT), and comparing the output of the SUT with the instantaneous acceleration of the shaker table at different frequencies sufficient to define the performance characteristics of the SUT within a selected frequency range, among other things. In another aspect, the method comprises calibration of a dynamic motion SUT by simultaneous direct measurement of position and time. In another aspect, the optical position sensor has an electrical output representative of position for attaining a desired degree of positional accuracy.

  • Patent number: 8563909
    Abstract: An apparatus and method improves the fault tolerance of a rocket or missile guidance system which includes a resonant sensor. When improper initialization is detected, the resonant sensor is reinitialized, repeatedly if necessary, until normal operation is achieved. Improper initialization is detected by comparing data from the guidance system with pre-specified physical limits to roll, pitch, yaw, and/or other features of the flight scenario. Embodiments can also detect a fault condition due to an error signal from a “Built-in-Test” (BIT) module. The initialization sequence initiated by the invention can be identical to the power-on sequence, or it can be a separate, reinitiating sequence. Subsequent resets are initiated as needed, for example until the burn of the rocket fuel and the associated vibrations have ceased and the resonant sensor has been successfully initialized.

  • Patent number: 8566057
    Abstract: A method for self-adjustment of a triaxial acceleration sensor during operation includes: calibrating the sensor; checking the self-adjustment for an interfering acceleration, with the aid of a measurement equation and estimated values for sensitivity and offset; repeating the adjustment if an interfering acceleration is recognized; and accepting the estimated values for sensitivity and offset as calibration values if an interfering acceleration is not recognized. The step of checking the self-adjustment includes: estimating sensitivity and/or offset and the variance thereof; determining an innovation as the difference between a measured value of the measurement equation and an estimated value of the measurement equation; testing the innovation for a normal distribution; and recognizing the interfering acceleration in the event of a deviation from the normal distribution.

  • Patent number: 8552739
    Abstract: In an electronic device and a method of correcting time-domain reflectometers, two channels of a time-domain reflectometer are connected to a corrector using cables, and the two channels are enabled to transmit pulses. Parameters Step Deskew and Channel Deskew of the two channels are zeroed. Resistance values of the two channels are measured simultaneously, and the value of the parameter Step Deskew of one of the two channels is adjusted according to the Resistance values of the two channels. Times of achieving the same resistance value of the two channels are measured after the cables and the connector have been disconnected, and the value of the parameter Channel Deskew of one of the two channels is adjusted according to the times of achieving the same resistance value. The adjusted values of the parameters Step Deskew and Channel Deskew are displayed through a display unit.

  • Publication number: 20130245985
    Abstract: Methods and systems for matching critical dimension measurement applications at high precision across multiple optical metrology systems are presented. In one aspect, machine parameter values of a metrology system are calibrated based on critical dimension measurement data. In one further aspect, calibration of the machine parameter values is based on critical dimension measurement data collected by a target measurement system from a specimen with assigned critical dimension parameter values obtained from a reference measurement source. In another further aspect, the calibration of the machine parameter values of a target measurement system is based on measurement data without knowledge of critical dimension parameter values. In some examples, the measurement data includes critical dimension measurement data and thin film measurement data.

  • Patent number: 8504308
    Abstract: A system and a method analyze fatigue damage of a bottom hole assembly (“BHA”), and more specifically, use a multi-scale approach for fatigue analysis of a BHA. Three length scales may be used in modeling of a BHA, namely the BHA scale, the component scale and the feature scale. Loading conditions for each collar/tool of the BHA may be determined, such as by use of a beam model, and may be applied to the finite element models for the collar/tool to determine the fatigue damage of each fatigue susceptible feature of each collar/tool. A cumulative fatigue damage of each critical feature may be determined, and the weakest component of the BHA may be identified. Prognostic and diagnostic implementation with well survey and drilling data may monitor fatigue damage of critical components of the BHA.

  • Patent number: 8473275
    Abstract: A method for emulating and debugging a microcontroller is described. In one embodiment, an event thread is executed on an emulator that operates in lock-step with the microcontroller. Event information is sampled at selected points. Trace information is also recorded at the selected points. As such, the event information and trace information are effectively pre-filtered. Accordingly, it is not incumbent on a designer to read and understand the event and trace information and sort out the information that is of interest. Instead, this task is essentially done automatically, helping the designer and reducing the probability of error. Furthermore, because only selected event and trace information is recorded, the resources of the in-circuit emulator system are not taxed.
