Abstract: The invention provides a printing control system for controlling a print-head. The printing control system includes a motor controller, a time-delaying generator coupled to the motor controller, and a timer coupled to the delay time generator. The motor controller is used for calculating the moving speed of the print-head reaching a printing position. The time-delaying generator is used for generating a delay time according to the moving speed. The timer is used for starting to count a printing time after the print-head reaches the printing position. When the printing time equals the delay time, the timer outputs a printing signal to control the print-head to jet out an ink drop.

Abstract: The present invention provides a self-sealing high-temperature biochemical reaction apparatus and a method for the same. The present apparatus has a microfluidic channel including a main channel chamber, an inlet sub-channel and an outlet sub-channel. The main channel chamber has an inlet and an outlet respectively communicated with the inlet sub-channel and outlet sub-channel. The inner diameters of the inlet sub-channel and outlet sub-channel are smaller than that of the main channel chamber. The present invention controls the temperature gradient of the main channel chamber and sub-channels during the biochemical reaction such that the microfluid itself becomes self-sealing material to seal the openings of the sub-channels during the high-temperature reaction. The microfluid would not be vaporized to adversely influence the reaction result.

Abstract: In a 3D display having a plurality of display regions and corresponding backlight regions, the image data is sequentially sent to the display regions. The respective light source(s) of the corresponding backlight region is/are turned ON after a response time of each display region, without waiting for a response time or times in the other display regions. The light source(s) is/are then turned OFF after a predetermined time period. The process repeats for further image data.

Abstract: An apparatus for controlling micro-fluid temperature is provided. The apparatus includes a chip, a fixed stand, a heat-absorption block, and an actuator. The chip has a reaction chamber for disposing a micro-fluid, and the temperature of the micro-fluid rises by heating the chip to reach the required reaction temperature. In the cooling-down operation, the heat-absorption block can contact the chip when pushed by the actuator, so as to dissipate the heat from the chip by way of heat conduction. Moreover, in the heating operation, the heat-conductive block is out of contact with the chip such that the micro-fluid in the chip is quickly heated, so as to reach the required reaction temperature of the micro-fluid rapidly.
