Method of calibrating depths of a seismic receiver array
A seismic receiver array has a plurality of seismic receiver channels, each coupled to a local surrounding in an earth formation. A formation-material-dependent response of each seismic receiver channel is determined, and associated with an assumed depth for the corresponding seismic receiver channel. The formation-material-dependent responses as function of the assumed depth are compared to an independent depth log of at least one petrophysical parameter of the earth formation as a function of depth along the borehole. Based on the comparison, a set of lags between said assumed depth and depth in the independent depth log is determined, that provides the best correlation between the formation-material-dependent response and the independent depth log of the at least one petrophysical parameter of the earth formation. The assumed depth of each seismic receiver channel can thus be aligned with corresponding depths in the independent depth log. |

Synthetic-aperture radar (SAR) imaging with range-resolved reflection data
SAR imaging may be performed with range-resolved reflection data, where a spread-spectrum signal, such as a code division multiple access (CDMA) signal, is transmitted instead of a simple frequency chirp. The reflected spread-spectrum signal may be analyzed to gather range-resolved reflection data. Range-resolved reflection data may be gathered at each angular view. This data may be used to construct a more accurate approximation of the Fourier transform of the desired image than can be done by a conventional SAR approach. The image may be reconstructed from this Fourier transform using Fourier inversion techniques similar to those used in conventional SAR approaches. The range-resolved reflection scheme generally requires somewhat more processing to recover the image as compared with conventional SAR systems, but provides a significantly more stable image with less degradation from effects that plague conventional SAR systems. This can eliminate the need for phase coherency altogether and also eliminate “phase drift,” which leads to image distortion. This may be especially well suited for high resolution imaging of relatively large targets. |

Method and apparatus for online condition monitoring of variable speed motor applications
The subject matter disclosed herein describes a method and system to monitor and identify vibrations in a rotational mechanical system. Various fault conditions in a rotating machine operating at variable speeds may be identified, at least in part, by identifying the multiple of the fundamental frequency, or order, at which the vibration occurs. The orders of vibration present in a measured vibration signal may be determined by finding an order spectrum of a measured vibration signal in the position domain. A fault vector is generated from the order spectrum that identifies the magnitude of each order of vibration present in the measured vibration signal. The fault vector may be plotted on a radar chart to provide a visual indication of the type of fault present in the mechanical system. Evaluation models for each fault determines a probability and magnitude for each fault condition being present in the sampled vibration signal. |

Controller and control method for internal combustion engine
A port injection valve injects fuel into an intake passage. An intake synchronous injection is to inject fuel in synchronization with an opening period of an intake valve. A single injection process is to execute only an intake air non-synchronous injection. A majority of a fuel injection period of the single injection process is prior to the opening timing of the intake valve. A controller causes, when switching a fuel injection process from the single injection process to a multiple injection process, an injection start timing of the intake air non-synchronous injection to be more advanced than an injection start timing of the single injection process prior to the switching. |
