  • Publication number: 20220120181
    Abstract: A system for navigation detection and inclination measurement of advanced hydraulic supports, including a detection device module, a signal transfer transmission module, connected to the detection device module, and used to integrate ultrasonic signals and inclination signals received from all advanced hydraulic supports and then wirelessly transmit all the signals to an analysis and processing module. The analysis and processing module, connected to the signal transfer transmission module, and used to receive the signals from the signal integration and transmission device for analysis, where if an analysis result shows an abnormal situation, an alarm will b e immediately given to a worker. If the analysis result shows a continuous abnormal situation, or a relatively large value indicating the abnormal situation is generated, a command will be immediately sent to make the advanced hydraulic supports stop operating in a current mode.

  • Publication number: 20220094255
    Abstract: The present invention provides an annular linear induction electromagnetic pump having axial guide vanes, wherein m axial guide vanes are uniformly arranged in a flow channel of the electromagnetic pump in a circumferential direction, a magnitude of m is equal to a number of external stators, and a length of each of the guide vanes is determined together by the number of the external stators, a central radius of the flow channel, a magnetic Reynolds number, and a wave number of a traveling magnetic field. The axial guide vanes can significantly mitigate the impact on the flow field stability caused by uneven circumferential disturbances of the magnetic field and flow field, thereby achieving a flow stabilization effect and greatly improving the flow stability in operation under off-design conditions.

  • Patent number: 11283342
    Abstract: An annular linear induction electromagnetic pump having axial guide vanes is provided. m axial guide vanes are uniformly arranged in a flow channel of the electromagnetic pump in a circumferential direction, and a magnitude of m is equal to a number of external stators. A length of each of the guide vanes is precisely determined by a parameter P, and the value of the parameter P is calculated together by the number of the external stators, a central radius of the flow channel, a magnetic Reynolds number, a wave number of a traveling magnetic field and the mean fluid velocity. The axial guide vanes can significantly mitigate the impact on the flow field stability caused by uneven circumferential disturbances of the magnetic field and flow field, thereby achieving a flow stabilization effect with less hydraulic losses and greatly improving the flow stability in operation under off-design conditions.

  • Patent number: 9766362
    Abstract: A system and a method use dual telemetry for tools located in a wellbore. A first telemetry system and a second telemetry system coordinate communication with the tools. Both the first telemetry system and the second telemetry system may transmit data regarding the tools and/or drilling conditions from the tools to a surface location simultaneously. The first telemetry system or the second telemetry system may communicate with the surface location if communication using the other telemetry system is interrupted. The first telemetry system and the second telemetry system may have a master/slave relationship so that data requests from a specific telemetry system do not interfere with data requests from the other telemetry system.

  • Patent number: 8866633
    Abstract: The present disclosure relates to a method to determine a clock signal when separate clocks are used. In one embodiment, a disciplined clock system comprising an update subsystem and a synthesis subsystem is provided. A first clock phase estimate is provided to the update subsystem and used, along with the update subsystem, to determine a frequency offset estimate and a phase offset estimate. The clock signal is determining using the frequency offset estimate, the phase offset estimate, and the synthesis subsystem. Alternatively, two clocks can be synchronized by generating a signal associated with a first clock; modulating the signal; transmitting the modulated signal; receiving the modulated signal by a receiver associated with a second clock; correlating the received signal; determining the time of arrival of the received signal; determining the time difference between the two clocks; and synchronizing the two clocks.

  • Patent number: 7272265
    Abstract: A method for padding, filtering, denoising, image enhancing and increased time-frequency acquisition is described for digitized data of a data set is described where unknown data is estimated using real data by adding unknown data points in a manner that the padding routine can estimate the interior data set including known and unknown data to a given accuracy on the known data points. The method also provides filtering using non-interpolating, well-tempered distributed approximating functional (NIDAF)-low-band-pass filters. The method also provides for symmetric and/or anti-symmetric extension of the data set so that the data set may be better refined and can be filtered by Fourier and other type of low frequency or harmonic filters.
