20120119673 | LIGHT SOURCE SYSTEM AND METHOD FOR DRIVING LIGHT EMITTING DIODES - A light source system and a method for driving light emitting diodes (LEDs) are provided. The provided light source system includes: an LED module having a plurality of LED strings operated under a direct current (DC) output voltage; and a driving unit coupled to the LED module, and used for providing the DC output voltage by adopting a boost means and generating a plurality of pulsation current signals according to a setting signal so as to respectively drive the LED strings, in which the frequencies of the pulsation current signals are higher than a predetermined frequency. | 05-17-2012 |

20120217855 | LIFTABLE SLIDE COVER MOUNTING STRUCTURE USING A SHEET METAL BRACKET MECHANISM - A liftable slide cover mounting structure consisting of two hinges, two metal sheet bracket mechanism, two sliding rails, two gears, two gear racks and two supplementary support mechanisms. Subject to the use of the sheet plate bracket mechanisms to hold the sliding rails instead of zinc alloy sliding rail holders, the weight of the liftable slide cover mounting structure is minimized. Further, when the cover panel is opened from the base member, the sheet plate bracket mechanisms are forced into engagement with the supplementary support mechanisms to support the cover panel in position for enabling the user to operate the display screen of the cover panel positively. | 08-30-2012 |

20150020351 | HINGE STRUCTURE - A hinge structure includes a first shaft, a second shaft, a pivot base and a position-limiting mechanism. The first and second shafts are pivoted on the pivot base. The position-limiting mechanism includes a first position-limiting portion, a second position-limiting portion and a position-limiting component. The first position-limiting portion is fixed to the first shaft. The second position-limiting portion is fixed to the second shaft. The position-limiting component is slidably disposed on the pivot base and has first and second ends opposite to each other. When the position-limiting component moves to a first position, the first end and the first position-limiting portion interfere with each other to stop the first shaft and the pivot base from rotating relatively. When the position-limiting component moves to a second position, the second end and the second position-limiting portion interfere with each other to stop the second shaft and the pivot base from rotating relatively. | 01-22-2015 |
20150052707 | HINGE STRUCTURE - A hinge structure includes a first shaft, a second shaft, a sliding component, a first pillar, and a second pillar. The second shaft is parallel to the first shaft. The sliding component includes a first sliding portion and a second sliding portion, wherein the first shaft and the second shaft are disposed through the first sliding portion and the second sliding portion respectively, and the first sliding portion has a first guiding slot and the second sliding portion has a second guiding slot. When the first shaft rotates with respect to the sliding component and moves the first pillar along the first guiding slot, the first pillar drives the sliding component to slide along the first and second shafts and move the second pillar along the second guiding slot, so as to drive the second shaft to rotate with respect to the sliding component. | 02-26-2015 |
