20080240094 | Method of transmitting an image file - A method for transmitting an image file uses an image application program which can cooperate with a web-phone application program. The web-phone application program is responsible for transmitting the image file. After the web-phone application program on a receiver side receives the image file, the image file is displayed on the operating interface of the image application program on the receiver side. | 10-02-2008 |
20100020226 | Web camera - The web camera of the present invention is used to capture the external images. The web camera of the present invention comprises a circuit control unit, a focal adjustment module, a focus adjustment button, an image capturing module, and a shutter button, wherein the focus adjustment module has an auto-focus mode and a fixed focus mode; the focus adjustment button is electrically connected to the focus adjustment module and the circuit control unit. The focus adjustment button is used to change the mode of the focus module to the auto-focus mode or to the fixed focus mode; the image capturing module is electrically connected to the circuit control unit, which is used to transform the external images into image signals; and the shutter button is electrically connected to the circuit control unit, which is used to send outward the image capturing signals. | 01-28-2010 |

20120249100 | HIGH BOOST RATIO DC CONVERTER - Disclosed is a high boost ratio DC converter, wherein the first and second switches are controlled by a control chip and the control chip controls the first and second switches in the following sequence: the first and second switches both conduct; the first switch conducts and the second switch is cut off; the first and second switches both conduct; the first switch is cut off and the second switch conducts thus making a first and second inductors and a first and second clamp capacitors charge to a first and second output capacitors. Then the first and second output capacitors discharge a load. Therefore, the load voltage output from the DC power supply will be boosted owing to the discharged load from the first and second output capacitors. The boost ratio is 4/(1−D). | 10-04-2012 |

20150194907 | GATE-BOOSTING RECTIFIER AND METHOD OF PERMITTING CURRENT TO FLOW IN FAVOR OF ONE DIRECTION WHEN DRIVEN BY AC INPUT VOLTAGE - A current-rectifying device includes a switching component and an impedance transformer. A conductance between first and second nodes of the switching component is controlled based on a voltage between high-impedance control and control-reference nodes of the switching component to determine an amount of current that is permitted to flow between the first and second nodes. The impedance transformer includes a positive input node electrically connected to one of the first and second nodes based on AC voltage swings, a negative input node, a positive output node electrically connected to the high-impedance control node, and a negative output node, and which senses an AC voltage swing derived from the AC input voltage with the positive input node and the negative input node, and provides an AC voltage swing between the high-impedance control and control-reference nodes that is greater than the AC voltage swing derived from the AC input voltage. | 07-09-2015 |

20120173791 | CONTROL METHOD AND ALLOCATION STRUCTURE FOR FLASH MEMORY DEVICE - A control method and an allocation structure for a flash memory device are provided herein. The flash memory device has a first memory module and a second memory module. Physical blocks of the first memory module and physical blocks of the second memory module are respectively divided into a plurality of groups, each of which has a plurality of the physical blocks. A first subunit and a second subunit of a first allocation unit are interleavingly written into a first group of the groups of the first memory module and a second group of the groups of the second memory chip respectively. Additionally, a first subunit and a second subunit of a second allocation unit are interleavingly written into a third group of the groups of the first memory module and the second group, respectively. | 07-05-2012 |
20140129764 | ALLOCATION STRUCTURE FOR FLASH MEMORY DEVICE - An allocation structure is used for a flash memory device. The flash memory device includes a first memory module and a second memory module. The first memory module and the second memory module respectively have a plurality of groups, and each of the groups of the first memory module has a plurality of physical blocks of the first memory module and each of the groups of the second memory module has a plurality of physical blocks of the second memory module. The allocation structure includes a first zone. The first zone is used to store a first allocation unit, and is formed by a first group of the groups of the first memory module and a first part of a second group of the groups of the second memory module. | 05-08-2014 |
