Title: Method for data compression
Inventor: HALE IRA D
IPC: H04N1/41
Filed: 1998-05-06
Granted: 2001-12-11
Abstract: The widely used JPEG standard algorithm for two-dimensional image compression may be adapted for compression of arrays of any dimension and data type, specifically for arrays of seismic data. Because the JPEG algorithm processes, more or less independently, small subsets (8 x 8 blocks) of larger images or arrays of data, such adaptations are particularly useful in applications that cannot maintain a large, uncompressed, multi-dimensional array in computer memory. JPEG-like methods enable compression and decompression of large arrays by iteration over sub-arrays that are small enough to reside in memory.  These algorithms lead to the concept of a compressed virtual memory. Special care must be taken in JPEG-like algorithms to avoid blocking artifacts, which are discontinuities between blocks of data that are compressed and decompressed independently. Fortunately, computationally efficient methods for suppressing these artifacts are well known. Of these methods, one has been adopted that enables much of the JPEG method to be reused. The JPEG-like method of the invention uses the JPEG methods for discrete cosine transform (although the forward and inverse transforms are reversed), and for Huffman encoding of the quantized transform coefficients. The method differs from JPEGs primarily in additional steps taken to avoid blocking artifacts, and in the quantization of transform coefficients.

Title: Automated interface generation for computer programs in different environments
Inventor: STEPHENSON JOHN W
IPC: G06F9/44
Filed: 1999-11-22
Granted: 2008-09-02
Abstract: Automated interface generation for computer programs operating in different environments is provided. An automated interface generation system, method, computer program product and article of manufacture is provided comprising an import utility and a runtime environment. The import utility imports a COBOL IMS transaction source file, parses the specified input and output message records, and generates an application programming interface.  The application programming interface operates with the runtime environment to take the data values from the language of a different environment and translate them to a formatted IMS  input message. This format is derived from the definition of the input message record in the COBOL  IMS transaction source file. After the IMS transaction has executed, the resulting IMS output message is translated back to the data values of the language of the different environment, said values including the results of the transaction. The translation step handles data conversion between different code pages, machine architectures, and program semantics, and handles the dynamic nature of IMS messages.

Abstract: Footwear is provided with a series of removable insoles, each being adapted to be detachably installed to the outsole. The insoles have a wearing surface which conforms to the shape of the user's foot, the wearing surface of each insole being configured to accommodate a progressively larger foot size, increasing the useful life of the footwear and optionally eliminating the sockliner. In the preferred embodiment the footwear comprises decorative lights of as many different colors as there are insoles in the series, and each insole is provided with an actuator positioned to activate a specific colour of light. Each insole may be colored or color coded to match the color of the lights activated thereby, and can be identified by the color code applied to either the lights or the insoles. The insoles may alternatively be integrated into a single insole with tear-away layers.

Abstract: The invention provides a binder or portfolio (10) for carrying looseleaf paper, books, school supplies, etc. wherein said binder includes an expandable gusset (18) attached to the front (12) and back covers (14) of the binder. The covers (12, 14) of the binder are foldably attached to a central spine (16) and the gusset is split into two sections running along the periphery of the inner sides of the covers. The gusset is provided with a means for releasable attachment (24) such that when the front cover of the binder is folded over the back cover of the binder, the two sections of the gusset may be attached to one another, thereby securing the contents of the binder inside. Preferably, the gusset is made from an elastic material such as neoprene and the releasable means of attachment is a zipper-type closure. This construction of the gusset from an expandable material allows oversized objects such as larger textbooks to be placed in the binder without damaging the structural integrity of the gusset and the binder when the binder is fastened shut. An embodiment is disclosed wherein the covers are provided with a window also substantially formed from an elastic material, further increasing the expandability of the binder. Means for securing such a gusset to a binder are also provided, specifically a means for biasing the gusset outward of the binder so that the gusset does not interfere with the insertion of items into the binder. This outward biasing of the gusset also facilitates the securing of the two portions of the gusset by the releasable closure means.

Granted: 2010-05-25
Abstract: A cassette sensing mechanism and a method for detecting the unevenness of a surface by detecting the difference between two paths on the surface. The mechanism contains two pawls connected to a connector at one end. The second end of one pawl contacts a portion of one path on the surface, and the second end of the other pawl contacts a portion of the other path on the surface. One path is smooth, and the other path contains grooves. A sensor on one pawl senses the relative position of the other pawl. The unevenness of the surface can be detected by monitoring the relative positions of the two pawls as the two pawls travel along the two paths. The sensing mechanism may be used for monitoring the position on a cassette in a sterilization system.

Abstract: A baled crop material processor for disintegrating baled crop material comprising a container, a disintegrator, a discharge opening and means for manipulating the crop material for disintegration by the disintegrator. The container, receives and contains the crop material. The disintegrator comprises a flail roller that is mounted within the container and has a number of flails pivotally mounted about it. The flail roller rotates about its own longitudinal axis in either a clockwise or counter-clockwise direction. The discharge opening is at the bottom of one of the side walls to discharge the disintegrated crop material either to the left or to the right of the processor and in a bidirectional processor, the operator may alternate between sides. The manipulation means comprises manipulator rollers having paddles positioned at an angle to the length of the roller to rotate the crop material without substantially breaking the crop material apart. The paddles are channel shaped with outwardly curved ends to grasp the baled crop material for rotation and then to pull out of the crop material due to the curved end as the roller is rotated. Further, the angled paddles guide the crop material longitudinally toward the centre of the crop material processor away from the front and back walls. Moreover, the sidewalls of the container are shaped to have a protrusion projecting into the container in close proximity to the paddles, a spacing below the protrusion to prevent the accumulation of loose material, and outwardly sloped wall portions above the protrusion.

Title: Fluorination
Inventor: VAN DER WESTHUIZEN DRIEKUS
IPC: C07B/
Filed: 2000-05-18
Granted: 2007-12-18
Abstract: A process for fluorinating a hydrocarbon substrate is by mixing it with an inert diluent and mixing the diluted substrate with a gaseous fluorinating reagent to form a foam reaction mixture. The fluorinating reagent reacts with the substrate in the form to foam product. The foam is separated into a liquid component which contains product and a gas component. Product is withdrawn from the liquid component which is then returned to the diluting step. Fluorinating reagent is fed into the gas component which is then recirculated to the mixing step. An installation for fluorinating a hydrocarbon substrate includes, in sequence as a circuit, a dilution stage, a mixing stage, a reaction stage and a separation stage. Liquid returning means feeds liquid from the separation stage to the dilution stage, and gas recirculation means feeds gas from the separation stage to the mixing stage.
