The flexible storage bag includes overlaying first and second sidewalls defining an internal volume that can be accessed from an open top edge. To evacuate air from the internal volume after the open top edge has been closed, the bag includes a one-way valve element attached to the first sidewall and communicating with the internal volume. To prevent the one-way valve element from becoming clogged by the opposing second sidewall, the bag also includes a clearance member that maintains at least a partial clearance between the first and second sidewalls proximate the valve element. The clearance member can take many forms such as a textured portion on the second sidewall that includes evacuation passages which provide air in the internal volume access to the valve element, a permeable element covering the valve element, and a rigid or compressible structure that spaces the second sidewall from the valve element.

The invention relates to a video compressing and encoding method with an alpha transparent channel, comprising the following steps of: inverting the acquired video image to the image in the format of RGB or YUV4:4:4/YUV4:2:2/YUV4:2:0; compressing the acquired data in the alpha transparent channel in a no-damage mode; encoding and compressing video data for the video image in the specific format according to the frame format of MPEG-2 I and saving the compressed data in the alpha transparent channel in the compressed data structure of the video image. The method realizes the encoding of a specific video picture, can use a standard MPEG2 encoder for encoding, and effectively reduces video bitrate when ensuring the high quality of the video so as to realize the video data encoding with high quality, high efficiency and low cost. Because the data of the alpha transparent channel and the compressed data of the video image are saved in the same file, the video compressing and encoding method not only simplifies the process of processing the image at the later period and the information sharing between file management and a program, but also reserves the original video which is not added with the data of the alpha transparent channel.

Compressed waveform data structure is proposed which is suited for segmentation of a plurality of samples of compressed waveform data into a plurality of frames and subsequent storage of each of the frames. The number of bits per sample of the compressed waveform data is variable between the frames, but uniform, i.e. the same among all of the samples, within each of the frames. Each of the frames has a same data storage size. Each of the frames includes, in a predetermined layout, an auxiliary information area for storing auxiliary information that includes compression-related information to be used for decompressing the compressed waveform data, and a data area for storing a plurality of samples of the compressed waveform data of the frame with each of the samples comprising a same number of bits. Thus, respective start positions of the frames and compressed waveform data in a memory can be fixed at predetermined positions common to the frames, so that readout control can be performed with ease.

The invention relates to a partial product compressed tree generating method based on a mixed compressed structure, by combining the characters of a 3 to 2 compressor and a 4 to 2 compressor and from a growing point of view, constructing the partial product compressed tree. It takes a 4 to 2 compressor as a root of the compressed tree, grows two branches upward on the root or directly receives four partial product signals and a carry input signal. If it grows branches, it determines to adopt a 4 to 2 or 3 to 2 compressor according to the number of signals to be compressed, and if the number of signals able to be received by the two branches at most is less than that of signals to be compressed, these branches continuously grow branches at their respective compression ratios until the number of signals able to be received by the top braches is up to or beyond that of signals to be compressed. It reduces the time and area of the partial produce compressed tree, reduces the total time delay and area of the multiplication or MAC, and provides the possibility of heightening the frequency and performance of a digital signal processor and reducing the cost of a chip.

A shockproof spindle includes a spindle inserted into an elastomer, a compressible structure, and a sleeve, a hollow cylinder, sequentially. The sleeve caps the elastomer while the elastomer presses on the top of the base fixed under the spindle. The ball keeps contact the chute of the spindle and the chute of the sleeve. In addition to all of the above, the elastomer held between the base and the sleeve absorbs the impact when a tool installed on the end of the spindle is shocked against the workpiece during operation process. Since the spindle works smoothly owing to the effect of the elastomer, the operators work more easily, and the damage or destruction of assembly precision, made by the impact, of the parts in the electric tool is avoided.
