Abstract: An image sensor anti-shake component includes a fixed component, a rotating component, a movable component, and a drive component. The fixed component includes a base, a cover, and a first circuit board. The rotating component includes a rotating platform, a second circuit board, and an image sensor. The movable component is connected to the fixed component and the rotating component such that the rotating component is axially fastened. When the drive component drives the rotating component to move, the rotating component can only rotate relative to the fixed component and cannot move. The drive component includes a coil and a permanent magnet that are in a one-to-one correspondence.

Abstract: A method for quantitative detection of trace polylactic acid microplastics (PLA MPs) in an environmental sample is disclosed, where the PLA MP in the environmental sample is depolymerized in an alkaline alcohol phase system, and the monomers thereof, i.e., lactic acid molecules were separated and recovered. Mass concentrations of lactic acid before and after reaction are quantitatively detected by HPLC-MS, and the initial mass concentration of PLA MPs in the sample is calculated using a formula. The minimum detectable concentration may be as low as 0.05 mg/kg. This method can quantify the trace PLA in water body, sludge, sediment, dust, and soil samples; no special treatment is required before heating in pentanol; use of such reaction conditions as heating and alkaline alcohol phase reduces reaction time substantially.

Abstract: The present invention is to provide a method for protecting online transaction safety between buyers and sellers, wherein, when a third-party server receives a good transaction information (including a first account information, a first good code and a selling price) from a first terminal device (seller), the third-party server sends the first good code to a verification unit to verify whether a good corresponding to the first good code has been used. If no, the first good code is locked. Then, the third-party server displays the good transaction information on a transaction platform and, when receiving a good purchasing message (including a second account information and the first good code) from a second terminal device (buyer) through the transaction platform, the third-party server deducts the selling price from the money corresponding to the second account information and adds the same to the money corresponding to the first account information accordingly.

Abstract: The method generates a candidate list in accordance with the contents of frames transmitted by access points and sequentially performs the handshaking operations with the access points on the candidate list to select a personal identification number (PIN) enabled access point. During the candidate list generating process, this method places Wi-Fi protected setup (WPS) PIN-enabled access points at high priority positions but eliminates non-WPS access points and WPS push button configuration enabled access points.

Abstract: The invention provides a digital image stabilization apparatus for compensating a jitter occurred in the ith frame among N frames of a video sequence, where each of the N frames includes a plurality of blocks, N is a natural number larger than or equal to 3 and i is an integer index ranging from 1 to N. The apparatus includes a determining module, a comparing module and an adjusting module. The determining module is to determine a block of background region BRi-1 in the (i?1)th frame. The comparing module, coupled to the determining module, is to compare the block of BRi-1 in the (i?1)th frame with the corresponding block in the ith frame so as to determine a jitter vector. The adjusting module, coupled to the comparing module, is to adjust the ith frame in accordance with the jitter vector to compensate for the jitter occurred in the ith frame.

Abstract: An external device includes a controller, a connector, a function circuit, and a storage device. The storage device stores firmware and an image file. The image file includes an installation program and a driver. The external device is coupled to a host via the connector. The firmware can drive the controller to generate a virtual optical disc drive in the host and load the image file to the virtual optical disc drive so as to start the installation program. When the host does not have the driver, the installation program can install the driver in the host. When the host has the driver, the host can drive the function circuit to work.
