20140333278 | DC-DC CONTROLLER AND MULTI-RAMP SIGNAL OPERATING METHOD THEREOF - A DC-DC controller and a multi-ramp signal operating method thereof are provided. The DC-DC controller includes a ramp generating unit, a comparator, a logic circuit and a switch unit. The ramp generating unit generates a first interior-ramp signal and a second interior-ramp signal alternately. The logic circuit generates the first and second control signals according to a comparison signal of the comparator. The switch unit is configured to switch one of the first interior-ramp signal and the second interior-ramp signal alternately to a second terminal of the comparator according to the first and second control signals. When the second interior-ramp signal is switched to the comparator, the first interior-ramp signal is charged to a first voltage level by the ramp generating unit. In another switch procedure, the second interior-ramp signal is charged to a second voltage level by the ramp generating unit. | 11-13-2014 |

20150272235 | NANOPARTICLE-EMBEDDED HEAT-GENERATING CLOTH AND METHOD FOR FABRICATING THREADS THEREOF - A nanoparticle-embedded heat-generating cloth comprises a fabric including a plurality of threads each having a plurality of spaces, and a plurality of heat-generating nanoparticles filling with the spaces and enclosed by the threads. The fabric generated by the present invention can be fabricated into various heat-generating clothing for users to wear. Since the heat-generating nanoparticles fill with the spaces and are enclosed by the threads, the drop amount of the heat-generating nanoparticles can be decreased to the minimum, or even no heat-generating nanoparticle drop is generated during washing of the clothing. In other words, the heat-generating clothing of the present invention can have prolonged lifetime. | 10-01-2015 |
