    摘要： Blind wavelet extraction and de-convolution is performed on seismic data to enable its practical usage in seismic processing and to provide quality control of data obtained in areas where data from wells are not available. The wavelet extraction and deconvolution are realized in the time domain by iteration, producing a mixed phase wavelet with minimal prior knowledge of the actual nature of the wavelet. As a result of the processing, the de-convolved seismic reflectivity is obtained simultaneously.

    摘要： A vehicle-mounted antenna device is one in which rain water etc. do not accumulate around an antenna mast base structure and allowing a reduction of the antenna height. The vehicle-mounted antenna device having an antenna mast is constructed mainly from a base plate (10) on which a circuit board (11) is placed, a housing (20), and the antenna mast base structure (30) having a foldable structure. The housing (20) has a water discharge flow path (40) formed in a linear shape as viewed as viewed from the upper portion of the vehicle-mounted antenna device. The water discharge flow path (40) extends continuously underneath the antenna mast base structure while being inclined relative to the base plate. The water discharge flow path is constituted by, for example, the water discharge groove (41), which is formed at the bottom portion of the antenna mast receiving groove (22), and the water discharge flow path-cum-antenna mast receiving groove (42).

    摘要： A micro stage with 6 degrees of freedom used in super-precise processing and sensing equipment filed is disclosed. The micro stage has three sets of electromagnetic driving units arranged in a horizontal plane for driving the micro stage to obtain movements within the horizontal plane with 3 degrees of freedom in X, Y and θz directions and three electromagnetic driving units arranged in a vertical direction for driving the micro stage to obtain additional movements with 3 degrees of freedom in Z, θx and θy directions. Direct driving by electromagnetic force is used in the invention, resulting in advantages over stacked structures of having a simple structure, a compact profile, a low driven weight center, low stator inertia, etc. Thus, there is no mechanical friction and damping, and high displacement resolution can be provided. The positioning error of a wafer table of a lithographic machine can be compensated, and the leveling and focusing of the lithographic machine can be achieved. The invention is also applicable in super-precise processing and sensing fields for achieving 6 degree-of-freedom motions. The micro stage, which operates on the basis of Lorentz Law, provides a linear relation between the output pushing force and the input electrical current, and thus the movement control technique for it can be well established.

    摘要： A method of distinguishing between daytime lighting conditions and nighttime lighting conditions based on a captured image by a vision-based imaging device along a path of travel. An image is captured by a vision-based imaging device. A region of interest is selected in the captured image. A light intensity value is determined for each pixel within the region of interest. A cumulative histogram is generated based on light intensity values within the region of interest. The cumulative histogram including a plurality of category bins representing the light intensity values. Each category bin identifies an aggregate value of light intensity values assigned to each respective category bin. An aggregate value is compared within a predetermined category bin of the histogram to a first predetermined threshold. A determination is made whether the image is captured during the daytime lighting conditions as a function of the aggregate value within the predetermined category bin.
