    摘要： A secured communication method for Wireless Mesh Network (WMN) in the field of network technology includes initial authentication request, authentication negotiation process of the authentication server and encrypted data communication via pre-shared key and other valid Mesh Point (MP) in the WMN in order to implement the functions of the WMN. The present invention not only meets the new needs of the WMN dynamic self-organization, but also provides the security performance almost the same as the IEEE 802.11 standard requirements. The present invention is easily applied into WMN upon IEEE 802.11 links, and furthermore, the architecture disclosed in the present invention is quite simple and easy to implement with full compatibility and flexibility.

    摘要： The electronic tag of the present invention is mounted under the door holder on the front and right side of the container and the lock bolt on the electronic tag is inserted into the holes of the container door handle and the door seal turnover panel. The lock cap screws to the lock bolt tightly, so that the lock bolt can not be pulled out from the electronic tag. The electronic tag adopts RFID technique, GPS satellite positing and identifying technique and un-touching approach switch door seal technique. When the lock cap screws onto the lock bolt, the door closing information is recorded; when the lock cap screws out from the lock bolt, the door opening information is recorded. The present invention identifies, reads and writes the freight information, logistics information, door seal information of the container through the electronic tag in an un-touching manner. The electronic tag has large storage volume, long life span, and good security. Besides, the electronic tag also has GPS that can position and identify the position of the container.

    摘要： Convenient side access to an image volume located within a two-pole, two-column main magnet of an MRI system is provided by rotating the symmetry axis of the magnet to be non-perpendicular with respect to the longitudinal axis of the patient transport and/or otherwise displacing the two column structures of the magnetic circuit so as to permit open and unobstructed access to the image volume along a direction perpendicular to the longitudinal axis of the patient transport.

    摘要： MRI images are selectively resized or "zoomed" by zero padding the time domain data. Fourier Transformation of the time domain data after zero padding provides spatial domain data which when displayed provide an image that is resized relative to images provided from the time domain data without zero padding. A "zoom" or magnification factor can be selected and the quantity of padded zeros varied in response to the zoom factor to provide different zoom ratios. Restricting zoom factors to certain values permits the fast Fourier Transform to be used in Fourier Transformation.
