    • The disclosure discloses a method and device for displaying a picture on a browser of a User Equipment (UE) as required. The method includes that: when a UE accesses a WEB page through a browser, the browser parses a received HTML text, and typesets the WEB page in manner of a default picture according to a result of the parsing; a visual area of the WEB page is calculated and a control within the visual area is acquired; and after it is determined that the control within the visual area includes an image control and each image control within the visual area has obtained a corresponding picture, the visual area is drawn. With the disclosure, when a user only wants to view part of the area of a WEB page, time waiting for displaying of the WEB page and data-flow consumption are reduced by merely downloading any picture of the WEB page that is within the scope of a screen.

    • The present invention provides a system and method of reducing image intensity variations during imaging acquisitions that utilize large encoding gradient pulses that are played out immediately before a center of k-space is sampled. The present invention includes an acquisition and sampling that implements a predetermined delay in sampling prior to sampling the center of k-space. The delay in sampling the center of k-space following sampling of a peripheral region of k-space maintains the steady state of the MR signal and reduces the image intensity variation caused by eddy current and gradient hysteresis. As such, the intensity variations throughout k-space may be reduced substantially and brought closer to the intrinsic noise level of the data acquisition.
    • 本发明提供一种系统和方法,该系统和方法在成像采集期间减小图像强度变化,其利用在k空间的中心被采样之前立即播放的大编码梯度脉冲。 本发明包括在对k空间的中心进行采样之前实现采样的预定延迟的采集和采样。 采样k空间周边区域之后的k空间中心的采样延迟保持了MR信号的稳定状态,并降低了由涡流和梯度滞后引起的图像强度变化。 这样,整个k空间的强度变化可以被显着地减小并且使其更接近数据采集的固有噪声水平。

    • A vehicle interior classification system and method in accordance with the present invention determines a classification relating to the interior of the vehicle, such as the occupancy status of a vehicle seat or the state of alertness of a vehicle driver, from one or more images of an appropriate portion of the interior of the vehicle acquired with an image capture device. The acquired images are preferably processed to limit the dynamic range of the images to obtain a resultant image which can comprise one or more regions of interest which are less than the total field of view of the image capture device. The resultant images are processed to extract information about features in the image and, in one embodiment, this processing is achieved with a two-dimensional complex discrete wavelet transform which produces a set of coefficients corresponding to the presence and/or location of the features in the resultant image. The set of coefficients produced with such a transform is potentially quite large and can be reduced, through described techniques, to a subset of the total number of coefficients, the members of the subset being selected for their ability to discriminate between the classifications defined for the system. By selecting a subset of the possible coefficients, computational requirements are reduced, as are hardware requirements in the system, such as memory. The selected set of coefficients (whether comprising all of the coefficients or a subset thereof) are provided to a classifier which processes the coefficients with a set of calibration vectors, that were determined when the system was calibrated, to determine the most probable classification for the portion of the vehicle interior.

    • A method of measuring and correcting eddy currents in a MRI system includes running a pulse sequence using bipolar gradient pulses and a first delay Te, to acquire a phase-difference image and a phase response of a static phantom that fills a majority of a field of view (FOV) of the MRI system, fitting the phase difference image to a two-dimensional second order polynomial, and changing the pulse sequence to provide a different delay. The method includes iterating running a pulse sequence and fitting the phase difference image and phase response with different delays to determine coefficients of the second order polynomial and a time constant of the phase response, correcting a pre-emphasis eddy current correction (ECC) system of the MRI system in accordance with the time constant of the phase response, determining an amplitude correction to reduce determined coefficients, and storing determined amplitude corrections in the pre-emphasis ECC system.
