Abstract: A roller assembly for a frameless sliding glass door has a bracket, a roller and at least one fastening device. The bracket is attached to the frameless sliding glass door and a track and has at least one elongated hole, an adjustment hole and a set screw. The at least one elongated hole is formed through the bracket near the lower end. The adjustment hole is formed through the lower edge of the bracket and communicates with the elongated hole in the lower end of the bracket. The set screw is threaded and corresponds with the adjustment hole. The roller is rotatable connected to the rear surface of the bracket in the upper end and mounted on the track. The fastening device is connected to the bracket and the frameless sliding glass door through the elongated hole and the corresponding through hole.

Abstract: A composite port connection device, and is provided with a plurality sets of connection ports for the user to connect them to various types of electronic devices. The connection ports include power output port and data transmission port. The major function of the invention is that, upon receiving the local power supply and data signals at input terminal, the power supply and the data signals are processed separately and independently, then they are connected to the related output ports respectively. Thus, the device enables a user to connect each of the respective output ports to each of the various electronic devices, hereby achieving the objective of providing power supply and realizing data transmission.

Abstract: A frameless glass door clamp has a clamping member, a base cover and a cap cover. The clamp member has a base side surface and a cap side surface. The base cover is mounted on the base side surface and has a panel, multiple flanges, a tapered face and multiple rounded outer edges. The cap cover is mounted on the cap side surface and has a panel, a multiple flanges, a tapered face and multiple rounded outer edges. Because the outer edges of the base and cap covers are rounded, the frameless glass door clamp is much less likely to injure people or damage objects and is easier to manufacture.

Abstract: A detailed identification method for articles has an image-taking step and a comparison step. The image-taking step includes acts of using a portable identification device having a close-up lens and a screen to take a detailed image of an undistinguishable article and displaying the detailed image on the screen with an enlarged size. The comparison step includes acts of recalling a detailed image of a legal article from a database and displaying the detailed image on the screen of the portable identification device with an enlarged size. The two detailed images are displayed on the same screen so a user can clearly compare the detailed images to judge whether the undistinguishable article is a fake. The detailed identification method for articles has mobility and can be conveniently and extensively used.

Abstract: An apparatus for displaying video output with dynamically adjustable drop rate to control playback quality. The inventive apparatus includes a playback engine, a pre-fetch engine, a rendering engine, and a drawing engine. The playback engine sends a pre-fetch requirement and a playback requirement. The pre-fetch engine receives the pre-fetch requirement, obtains frame data according to the pre-fetch requirement, and stores it in a pre-fetch buffer. The pre-fetch engine also adjusts the drop rate of related conditions of the frame data. The rendering engine obtains frame data, decodes, and filters the frame data. The drawing engine outputs the frame data.

Abstract: A system and method for extracting data from recording media scan a recording media so that a plurality of key frames and a plurality of time intervals can be extracted, wherein each of the plurality of key frames and each of the plurality of time intervals correspond to one of the scenes in the recording media. Afterwards, at least one selected key frame can be acquired. Eventually, a multimedia file can be outputted according to the selected frame. By acquisition of the plurality of key frames, the present invention allows of processing only key frames such that the amount of information needed processing can be reduced. Not all frames of the desired scenes are extracted from the recording media until a user output a multimedia file, so that the processing time for extracting data from the recording media can be concentrated in outputting multimedia files.

Abstract: An apparatus of producing preview files for previewing data frames. The inventive apparatus includes a playback engine, a rendering engine, and a drawing engine. The playback engine evaluates source frame data to obtain source frame grades, receives preview grade information, and sends a preview requirement according to the preview grade information. The rendering engine receives the preview requirement, obtains frame data from files according to the preview requirement and the source frame grades, and transfers the frame data into preview files. The drawing engine receives the preview frame files and outputs preview frames of the preview files.
