摘要： A backlight driving system driving a plurality of lamp groups comprises a phase controller, a pulse width module (PWM) controller, a plurality of power stages, a plurality of transformers and a plurality of switch circuits. The phase controller generates a plurality of phase signals. The PWM controller generates PWM signals.The power stages receive and convert direct current (DC) signals from an external power source to alternative current (AC) signals under the control of the PWM signals. The transformers receive and boost up the AC signals from the power stages to drive the lamp groups. The switch circuits alternatively transmit the DC power signals from the external power source and the PWM signals from the PWM controller to the power stages so as to control outputs of the power stages.

摘要： The fluid acceleration pipe includes a main body having a pipe cavity and defining a central axis. The whole inner surface of the main body is exposed to the pipe cavity. The main body is formed with at least 3 spiral ribs arranged spacedly along a perimeter direction of the main body. A spiral groove is formed between any two adjacent ones of the spiral ribs. A column-shaped imaginary datum plane is defined by the most bottom portion of each spiral groove about the central axis. A projection of the most top portion of each spiral rib on the imaginary datum plane defines a spiral line. The lead angle of the spiral line is 50 to 60 degrees. The top portion of each spiral rib has a convex-arc-shaped surface, and the bottom portion of each spiral groove has a concave-arc-shaped surface.

摘要： A method and a system of establishing depth of field data of a 3D image, applicable to a 3D image including a first and a second visual image. The system includes a storage module, an offset calculator, and a comparator. An offset vector matrix includes data fields in the same number as that of pixels of a first visual image. An offset calculator divides a reference frame by taking an ath first pixel of the first visual image as a center, and finds out a target frame having a minimum grayscale difference value with the reference frame from a second visual image, so as to calculate an offset vector value according to the minimum grayscale difference value. A comparator determines that the offset vector values of all the ath first pixels are recorded in the offset vector matrix, so as to convert the offset vector matrix into a depth map.
