Abstract: A sheet metal exterior sheathing element particu1arly suitable as a roofing tile. The tile has inter-engageable channels on its opposing longitudinal sides, one channel (6, 7) being on the underside and the channe l (9) on the upperside of the tile. A mounting tab (10) extends from adjacent the upperside channel (9) substantially co-p1anar to the body of the tile. The channels enable two tiles (1a, 1b) to be joined in an over1apping side by side re1ationship with their corresponding channel sections engaged. Each tile (1a, 1b) can be fixed to a supporting structure by their mounting tabs (10). A third tile (1c) can then be joined longitudinally of the first two tiles (1a, 1b) by engaging its underside channel (6) over and about their joined upperside channel sections (9). It can also be fixed to the supporting structure and the steps repeated to sheath a desired area.

Title: Subband encoding and decoding system
Inventor: TANIGUCHI SHOHEI
IPC: H04N19/70
Filed: 2000-07-25
Granted: 2003-12-23
Abstract: A band splitting section a01 splits an encoder input signal s00, entered into a subband encoding apparatus, into k band components. The band splitting section a01 outputs a subband signal s01 for each of n (<k) split bands, where n is determined by a processible upper-limit frequency on each application. A scale factor producing section a02 detects a maximum amplitude level of the subband signal s01 for each of n split bands. Then, the scale factor producing section a02 produces scale factor information s02 representing a normalized scale factor. A bit allocation producing section a04 outputs bit allocation information s04 for each of n split bands. A bit allocation value 0 is assigned to each of (n+1) to k split bands. A  requantizing section a06 requantizes the subband signal s01 for each split band. A frame constructing section a07 constructs a coded frame.

Abstract: The thickness (e) of the separation layer (4) decreases in the direction of flow (f) of the fluid. The membrane has an inorganic rigid porous support (2) defining at least one circulation channel (3) for the fluid to be treated to circulate in a given direction (f). The surface of the channel is covered with at least one layer (4) for separating the fluid, with a fraction called the permeate passing through the layer and support. The thickness of the separation layer decreases continuously or in steps in the direction of flow. The steps each have the same length in the direction of flow. The channel has a cylindrical or polygonal section. Process for making such a membrane, by covering the surface of the channel with a separation layer of decreasing thickness in the direction of flow of the fluid. The thickness decreases as a function of the gradient of the fluid pressure so the flow of permeate is constant along the channel. The length of each channel is divided into sections of equal length and the surface of each channel is covered with a separation layer by depositing it, starting with the section at the inlet end of the channel and reducing the length for each successive deposit. Alternatively, the porous support is placed vertically and each channel is filled with a suspension of the deposit of the separation layer and the channel is emptied progressively so the deposit time for one end of the channel is greater than that of the other.

Granted: 2001-12-04
Abstract: A method and apparatus for use in a digital video delivery system is provided. A digital representation of an audio-visual work, such as an MPEG file, is parsed to produce a tag file. The tag file includes information about each of the frames in the audio-visual work. During the performance of the audio-visual work, data from the digital representation is sent from a video pump to a decoder. Seek operations are performed by causing the video pump to stop transmitting data from the current position in the digital representation, and to start transmitting data from a new position in the digital representation. The information in the tag file is inspected to determine the new position from which to start transmitting data. To ensure that the data stream transmitted by the video pump maintains compliance with the applicable video format, prefix data that includes appropriate header information is transmitted by said video pump prior to transmitting data from the new position. Fast and slow forward and rewind operations are performed by selecting video frames based on the information contained in the tag file and the desired presentation rate, and generating a data stream containing data that represents the selected video frames. A video editor is provided for generating a new video file from pre-existing video files. The video editor selects frames from the pre-existing video files based on editing commands and the information contained in the tag files of the pre-existing video files. A presentation rate, start position, end position, and source file may be separately specified for each sequence to be created by the video editor.
