Abstract: An automatic adjustment method includes: drawing a closing symbol in case of emergency during train operation, and determining a closed section for adjusting a train operation diagram and adjustment conditions for the operation diagram by the closing symbol; obtaining a train set to be adjusted based on the adjustment conditions for the operation diagram; obtaining a train with failure in the closed section, and registering resource occupancy based on the closing symbol and the train with failure in the closed section to generate a resource occupancy list; performing station track adjustment and calculation, arrival and departure time adjustment and calculation, and section operation time adjustment and calculation on each train in the train set to be adjusted based on the resource occupancy in the resource occupancy list, and obtaining a corresponding adjustment result; and applying the adjustment result of each train to a corresponding planned line in the operation diagram.

Abstract: A touch pad device for a portable computer includes a key deck 20; a touch region 24 formed on a portion of the key deck 20; penetration portions 28 extending through the key deck 20 while being adjacent to the touch region 24; push buttons 32 integrally formed with the key deck 20 while being able to deform elastically inside the penetration portions 28; a touch pad 40 formed on a lower surface of the key deck 20 in a position corresponding to the touch region 24 for information input; a cover button 30 mounted on an upper surface of the key deck 20 to cover at least the push buttons 32 and the penetration portions 28, the cover button 30 having first and second button units 31 and 31? adapted to deform elastically and compress the push buttons 32; and a board 42 having switches 44 toggled on/off by pushing the button units 31 and 31?. The touch pad device is advantageous in that it has a minimized number of components, a simple assembly process, and a low manufacturing cost.

Abstract: The present invention discloses a DC-to-DC step-up converter to which a logic control unit is added in order to reduce the ripples of a DC output voltage and improve the power quality. The converter of the present invention comprises a step-up circuit, a ring oscillator, a divider circuit, a PFM (pulse frequency modulation) comparator and a logic control unit. The step-up circuit is used to step up a source voltage to generate a DC output voltage. The ring oscillator is used to generate an oscillator output signal. The divider circuit receives the DC output voltage to generate a feedback voltage. The PFM comparator compares the feedback voltage with a reference voltage to generate a comparator output signal to control outputting of the oscillator output signal.
