20090284850 | DEVICE AND METHOD FOR LOCKING LENS - A device and a method for locking lens in a lens holder are provided, wherein the lens is configured in a voice-coil motor (VCM) of a camera module of a cell phone and the VCM has a lens holder for a lens being fixed inside. The device includes a circumgyration stop instrument having a bottom surface for urging against the top surface of the lens holder for preventing a lateral stress and a lateral movement from occurring on the lens holder while the circumgyration stopping unit is coupled with the lens holder. | 11-19-2009 |
20090284851 | DEVICE AND METHOD FOR LOCKING LENS - A device for locking lens and a method for the same are provided. The device is used in a voice-coil motor of a photographing module of a cell phone. The voice-coil motor has a lens-stand for a lens being turned to a locking depth inside. The device includes a circumgyration-stop instrument having a first sustaining surface, and a focusing ring having a turning end. A turn-locking length of the turning end is equal to the locking depth inside. The device includes a circumgyration-stop preventing a pressure being persisted to apply on the lens as the focusing ring finishes the turn of the lens. The first turn-stop surface props the first sustaining surface as the focusing ring is turned to an extremity of the turn-locking length. The focusing ring accordingly escapes the circumgyration-stop instrument for finishing the focusing of the lens in the lens-stand. | 11-19-2009 |

20100260467 | CAPTION REMOVAL METHOD FOR DIGITAL VIDEO EDITING SYSTEM - A caption removal method for a digital video editing system includes the following steps. A video frame of a video sequence is inputted. A high level executing stage is provided. The high level executing stage includes the step of recovering the structural region of the temporal domain in the video frame and the step of recovering the structural region of the spatial domain in the video frame. A low level executing stage is provided. The low level executing stage includes the step of recovering the non-structural region in the video frame. | 10-14-2010 |
20130100303 | Video Stabilization System and Method - A video stabilization method includes detecting a plurality of feature points of an inputted image frame. Next, a block motion estimation is performed onto the inputted image frame according to the feature points, thereby generating a plurality of block motion vectors corresponding to the feature points. Then, the block motion vectors are converted to a histogram to perform a statistical process. Thereafter, an initial static background motion vector is determined according to a statistic value of the histogram. Thereafter, a Gaussian distribution model and a Maximum a Posteriori (MAP) estimation are adopted to correct the initial static background motion vector to generate a global motion vector. Then, a smoothing process is performed onto the global motion vector to generate a smoothed global motion vector. A video stabilization system is also provided here | 04-25-2013 |

20120305531 | Automatic Welding Method - An automatic welding method includes a preliminary step and a joining step. The preliminary step is configured to place a metal object having a multi-dimensional curved weld zone on a platform, and to clamp a welding torch with a welding torch clamping device. The joining step is configured to generate a relative movement between a tip of the welding torch and the multi-dimensional curved weld zone of the metal object, and to electrify the welding torch to weld the metal object by way of short circuiting arc transfer. An angle difference between a reference position and an instant position of the welding torch is 0 to 135 degrees when the welding torch welds the metal object, so as to keep the slag from spraying, wherein the welding torch is at the reference position when the tip thereof is pointed straight down towards the ground. | 12-06-2012 |
20140183166 | MANUFACTURING METHOD FOR ADVANCED HIGH-STRENGTH STEEL WHEEL AND JIG DEVICE THEREOF - The present invention relates to a manufacturing method for advanced high-strength steel (AHSS) wheel, comprising the following steps. Take an AHSS with at least 590 MPa of tensile strength for rolling to circular ring of a rim. Apply low heat input welding, such as the cold metal transfer (CMT) welding or the gas tungsten arc welding/tungsten inert gas arc welding (GTAW/TIG), at the junction of the rim to form a hollow cylindrical rim. Then perform hole expanding and spinning/roll forming operations to the rim. Take another AHSS with at least 980 MPa of tensile strength for pressing and forming a disk. Apply low heat input welding, such as cold metal transfer (CMT) welding, to the rim and the disk to produce a wheel. According to the present invention, the welding quality of products can be improved significantly; the fatigue lifetime of wheels can be enhanced; and wheels are lightweight. | 07-03-2014 |

20160064293 | SEMICONDUCTOR ARRANGEMENT AND FORMATION THEREOF - Forming a semiconductor arrangement includes non-destructively determining a first spacer height of a first sidewall spacer adjacent a dummy gate and a second spacer height of a second sidewall spacer adjacent the dummy gate based upon a height of a photoresist as measured using optical critical dimension (OCD) spectroscopy. When the photoresist is sufficiently uniform, a hard mask etch is performed to remove a hard mask from the dummy gate and to remove portions of sidewall spacers of the dummy gate. A gate electrode is formed between the first sidewall spacer and the second sidewall spacer to form a substantially uniform gate. Controlling gate formation based upon photoresist height as measured by OCD spectroscopy provides a non-destructive manner of promoting uniformity. | 03-03-2016 |

20150295421 | ACTIVE ISOLATED CIRCUIT FOR PRECHARGING AND DISCHARGING A HIGH VOLTAGE BUS - An active isolated circuit is provided for precharging and discharging a high voltage bus, such as within a hybrid electric vehicle, in a quick, efficient, and optimal manner. The circuit can include a battery, a DC-DC converter coupled between the battery and a main contactor, the main contactor coupled between the converter and a bus for selectively connecting the battery to the bus through the converter, and a control module for controlling the converter to selectively precharge the bus from the battery and selectively discharge the bus to the battery. The converter can be configured to isolate the battery and the bus. When a precharge signal is generated, the bus can be precharged from the battery through a transformer in the converter. The bus can be discharged to the battery through the transformer in the converter when a discharge signal is generated. | 10-15-2015 |
