20080266681 | Auto-focus lens module - An auto-focus lens module that uses electromagnetic force as well as spring force as driving force to drive the lens for auto-focusing is formed by a rectangular base, two copper plates, an insulation spacer, four magnets, a lens holder, a lens, a coiled spring, a coil, and a rectangular top cover. The lens holder, the lens and the coil form a lens set that moves synchronously. The coiled spring is between the coil and the lens and is elastically supporting between a circular slot of the lens holder and the top cover while the four magnets are respectively located outside the coil symmetrically and equidistantly, on four corners of the rectangular base so that the structure and volume of the lens module are simplified and minimized. Moreover, the distance between the coil and the magnets is shortened so that the electromagnetic force therebetween is increased. Furthermore, the diameter of the coiled spring is reduced for improving stability of the spring force. | 10-30-2008 |

20130238913 | APPARATUS AND METHOD FOR POWER MANAGEMENT - An apparatus for power management for use in a mobile device includes an RF (Radio Frequency) circuit, a power amplifier, a processor, and a DC to DC (Direct Current to Direct Current) converter. The processor is configured to generate a baseband signal. The RF circuit is configured to generate an RF signal according to the baseband signal. The power amplifier is configured to amplify the RF signal according to a supply voltage so as to generate an output signal. The processor is configured to detect an envelope of the RF signal, and to generate a control signal according to the envelope of the RF signal. The DC to DC converter operates in an APT (Average Power Tracking) mode or an ET (Envelope Tracking) mode so as to generate the supply voltage. | 09-12-2013 |

20140265631 | ELECTRONIC DEVICE FOR PREVENTING AN ACCIDENTAL TOUCH AND OPERATING METHOD THEREOF - An electronic device for preventing an accidental touch and an operating method thereof are disclosed, where the electronic device includes a first input device, a second input device, synthetic aperture radar and a main system. The synthetic aperture radar can sense whether a charged body is positioned near the second input device. When the charged body is positioned near the second input device, a voltage state of the synthetic aperture radar is pulled to a first logic level. When the voltage state of the synthetic aperture radar is in the first logic level, the main system disables the first input device. | 09-18-2014 |

20120217523 | LIGHT EMITTING DIODE PACKAGING STRUCTURE - A light emitting diode (LED) packaging structure comprises a base, a LED chip and a packaging colloid. The LED chip is disposed in the base. The packaging colloid comprises a first optical resin material and at least one second optical resin material. The first optical resin material is transparent and packages the LED chip. The second optical resin material is disposed to a side of the first optical resin material. The second optical resin material is doped with a second fluorescent-powder. By disposing multilayered second optical resin materials, the fluorescent-powder is far from the LED chip to prevent the fluorescent-powder from being heated to cause light attenuation, thereby extending the service life of the LED chip. | 08-30-2012 |
20130119415 | LED PACKAGE STRUCTURE FOR ENHANCING MIXED LIGHT EFFECT - An LED package structure for enhancing mixed light effect comprises: at least one first light emitting chip; at least one second light emitting chip, a frame structure having a first containing portion, a second containing portion, a spacing portion and a light mixing area; a first colloid, doped with a green-light phosphor and filled into the first containing portion; a second colloid, filled into the second containing portion; and an encapsulating colloid, packaged and filled into the light mixing area. This design can enhance the light emission efficiency and achieve a uniform light-mixing dot light source. | 05-16-2013 |
