Title: Method and apparatus for determining a bit rate need parameter in a statistical multiplexer
Inventor: CHEN JING YANG
IPC: H04N21/434
Filed: 2000-09-27
Abstract: A statistical multiplexer for coding and multiplexing multiple channels of digital television data, or multiple panels of HDTV digital television data. A bit rate need parameter is determined for each encoder in a stat mux group by scaling the complexities of previous pictures of the same and different picture types. Scaling factors based on an activity level, motion estimation score, and number of pictures of a certain type in a GOP, may be used. Moreover, the scaling factors may be bounded based on a linear or non-linear operator to prevent large variations in the factors. An encoding bit rate is allocated to each channel based on its need parameter.

Title: Arrangement and operation of dryer between shrinkage compactors to control residual shrinkage of knitted fabric below tumble drying
Inventor: CATALLO FRANK
IPC: F26B13/10
Filed: 2000-10-18
Abstract: Apparatus and a related method control within acceptable limits, of less than two percent(2%), residual shrinkage in garments to be made from a knitted fabric tube or open web. The apparatus and method also apply to other fabrics subject to high shrinkage. The knitted fabric is passed continuously in a moist condition through a first shrinkage compactor. Then the fabric is carried on an endless belt through a special dryer in a relaxed condition to allow loops of knits to shorten. A series of nozzles are arranged above and below the fabric in an alternating format to cause the fabric to wave in the dryer still in the relaxed condition. The web is then conveyed still in the relaxed condition to a second shrinkage range for final shrinking to a desired weight per surface area with less than two percent(2%) residual shrinkage.      Thus the garments are safe from further shrinking in home tumble dryers.

Title: Gas turbine
Inventor: AKAGI KOUICHI
IPC: F01K23/02
Filed: 2001-01-10
Abstract: Gas turbine blade ring is cooled by steam of which temperature, pressure and flow rate are controlled so that clearance between moving blade tip and blade ring is maintained appropriately. Steam from steam turbine bottoming cycle (10) flows into blade ring cooling passage (8) of gas turbine (1) via piping (12) for cooling blade ring. The steam having cooled the blade ring is supplied into transition piece cooling passage (9) of combustor (3) for cooling transition piece and is then recovered into the steam turbine bottoming cycle (10) via piping (14). While the steam cools the blade ring, temperature, pressure and flow rate of the steam are controlled so that thermal elongation of the blade ring is adjusted and the clearance at the moving blade tip is controlled so as to approach target value. Thus, the clearance is maintained as small as possible in operation and gas turbine performance is enhanced.

Filed: 1999-07-29
Abstract: A method of dispensing a prescribed medication, in pill form, and verifying that the medication dispensed is the prescribed medication. A medication identified from a prescription (P) is dispensed into a container (C). An ima ge of the dispensed pills is taken (14) and processed to obtain a set of characteristic features of the pill. These features include the coloration, shape, size, and any surface features of the pills. These features are then automatically compared (16) with those of all the pills which can be dispens ed by a dispensing apparatus (12). If a pill can be uniquely identified as the correct pill, the container of pills is accepted. Otherwise, the container i s rejected. If, as a result of the processing, a determination cannot be made,  the container is provisionally rejected and is subsequently inspected by a pharmacist to determine if the prescription is correctly filled.

Title: Manual installation tool for installing u-nut fasteners
Inventor: GOSIS ANATOLY
IPC: B25B31/00
Filed: 2001-04-03
Abstract: A U-nut type fastener installation tool, for installing individual U-nut fasteners from a vertically stacked,nested, or collated strip or array of such fasteners disposed within a magazine portion of the tool, comprises a base portion and the magazine portion which is pivotally mounted upon the base portion. The magazine portion also serves as an operator handle. A biasing spring within the magazine biases the collated strip of fasteners toward a dispensing position.

Patent CA-2344915-A1 (CA)
Inventor: WU SIU-WAI
IPC: H04N7/50
Filed: 1999-08-27
Abstract: A method and apparatus are provided for detecting scene changes between successive fields in a digital television signal. I-frames, which start new GOPs, are aligned with scene changes. In a preprocessing stage (205, 210), the change in the sum of pixel differences between consecutive odd fields, or consecutive even fields, is calculated for every consecutive input field. A scene change is detected when a large positive value in the change of sum is followed by a large negative value therein. A decision of which picture type to use is not made until a final encoding stage (225, 235). I-frames can be inhibited when an encoder buffer level is too high. A counter resets the scene change indication to avoid a perpetual scene change state for transitions from still to motion. In film mode, the MPEG-recommended frame-based encoding is deactivated when a scene change occurred on a field boundary (e.g., when there is no redundant field in the picture).
