A transverse induction logging tool having a transmitter and receiver for downhole sampling of formation properties, the tool having a symmetrical shielded split-coil transmitter coil and a bucking coil interposed between the split transmitter coils to reduce coupling of the transmitter time varying magnetic field into the receiver. Respectively fixed at one side and two ends of the cutting base is a sliding plate that has a sliding rail pivotally connected with two ends of a pressing rod respectively, so as to let the front end of the coiled band pass under the pressing rod to run out of the frame while having the pressing rod lifted up. The additional information may be information about the calling party initially downloaded to the memory by a subscriber. The distribution equipment provides the authorization data in a control word of a frame header of a VDSL frame. Within the computer, a model of polarization properties of the LCD panel is developed based on estimations of what the physical parameters of the LCD panel are believed to be.
