Patent CA-2133009-C (CA)
Inventor: HARASAKI HIDENOBU
IPC: H04N21/434
Filed: 1994-09-27
Granted: 1998-09-22
Abstract: In a transmission error correction code appending device which receives a variable bit rate signal transmitted at a variable bit rate and comprising a plurality of information bytes, a transmitting circuit transmits, unless a timer circuit produces a time-out signal, the information bytes to a correction code appending circuit and transmits, when the timer circuit produces the time-out signal, zero bytes to the correction code appending circuit subsequently to the information bytes so that the information bytes and the zero bytes constitute first through N-th data bytes of first through M-th data groups, where each of M and N represents a predetermined plural and natural number.          The correction code appending circuit consecutively supplies an interleaver with first through M-th blocks, each comprising the first through the N-th data bytes and first through P-th error correction code bytes as first through Q-th block bytes, where P represents a prescribed natural number, Q being equal to (N + P).  An informing signal producer produces an informing signal when the interleaver receives the first block byte of the first block.  The timer circuit produces the time-out signal when the timer circuit times a preselected time interval from a time instant at which the timer circuit receives the informing signal.

Abstract: Disclosed is a hyperacuity printing system for rendering halftoned image data on a recording medium. The printing system includes a data source for supplying grayscale input image data and halftoning circuitry for receiving the grayscale input image data from the data source and transforming the grayscale input image data into multi-bit value output data. The halftoning circuitry includes a look-up table for providing the multi-bit value output data where the multi-bit value output data define halftone dots, the halftone dots being arranged in the look-up table as a continuum from a lowest density value to a highest density value corresponding to the grayscale input image data, the halftone dots having a reference which is a predetermined position from a defined origin in the look-up table. Further included in the printing system is addressing circuitry providing a first set of address lines and a second set of address lines defining a screen stored in the memory, the first set of address lines and the second set of address lines providing x and y address values defined by a desired screen angle. The addressing circuitry includes rotation circuitry for modifying the x and y address values thereby rotating the halftone dots, resulting in rotated halftone dots. The addressing circuitry also includes shifting circuitry for modifying the x and y address values thereby shifting the reference point of the halftone dots away from the predetermined position from the defined origin in the look-up table, the shifting and the rotating occurring while the halftone dots are being read from the look-up table. Finally there is a modulating device for receiving the multi-bit value output data from the halftoning circuitry and converting the multi-bit value output data into a form which can be directly utilized by a writing device for writing the multi-bit value output data onto the recording medium.

Granted: 2002-02-26
Abstract: The present invention describes methods of screening for or selecting a catalytic antibody effective to cleave a target peptide. In particular, in the selection method of the present invention a phage gene is selected that encodes a gene product necessary for the production of a phage. The phage, carrying the modified gene is introduced into a host.  Also, a library of rearranged immunoglobulin genes in a cloning vector is introduced into host cells. The host cells are grown under conditions in which the immunoglobulin genes are expressed in the host cells. The presence of antibodies capable of cleaving the target peptide is identified on the basis of production of phage.

Title: A method of protecting against neuron loss
Inventor: LANDFIELD PHILIP W
IPC: A61K31/66
Filed: 1994-07-14
Granted: 2007-04-24
Abstract: The present invention pertains to a method of protecting against neuron loss in a subject by administering a compound that protects against neuron loss by acting through a vitamin D receptor. So me of these compounds may prevent or retard neuron loss by regulating intraneuronal and/or peripheral calcium and phosphate levels. Other compounds of the invention act through a vitamin D receptor to protect against neuron loss through mechanisms not involving calcium or phosphate regulation. A preferred compound is a biologically active form of vitamin D, a precursor, metabolite, or analog of vitamin D. A preferred form of vitamin D is calcitriol. In another embodiment, the compound is a compound that acts by modulating the biological activity of vitamin D, a precursor, metabolite, or analog of vitamin D. For example, the compound may modulate the biological activity of the vitamin D compound by regulating the amount of the vitamin D compound which is available to protect against neuron loss or it may act by altering the abili ty of the vitamin D compound to protect against neuron loss. In an alternative embodiment, the compound is a compound that protects against neuron loss through a mechanism similar to that of the vitamin D compound but not involving a vitamin D receptor. The compound is administeredto a subject in an amount and over a period of time effective to protect against neuron loss.

Title: Multi-layer blown-film extrusion die
Inventor: BENTIVOGLIO ALFREDO
IPC: B29C48/10
Filed: 1997-02-20
Granted: 2000-10-10
Abstract: This invention relates to a Multi-Layer Blown-Film Extrusion Die. An Extrusion Die is a key component of extrusion equipment, used in manufacture of Blown film for packaging industry. Although this Extrusion Die relates to production of five or more layers of blown films, it can also be used for production of lesser number of layers. While in the conventional outside fed die, melt was to be conveyed around the die in a fanning-out configuration, in this invention the polymer melt is split into two streams, before being fanned or spread around the circumference. Polymer melt enters several spiral or helical grooves prior to joining the gap that enjoins melt with other layers of the melt streams. The dimensions of spiral grooves and lands are carefully calculated, keeping in view relevant factors such as melt viscosity, shear sensitivity temperature and pressure requirements etc.

Abstract: An improved method of tracking a camera in dynamic chroma-keying of the type in which a foreground object is photographed against a multicolored chroma-key screen. The multicolor patterns are created by projection oii a monochrome screen, for example by projecting light through a mask on a screen colored with the chroma--key color. The projection of multiple patterns can emulate the use of a single pattern having multiple levels of detail, and can enable lateral tracking of the camera. Sequentially projecting known transformations (for example, rotations) of a pattern adds an extra degree of freedom which further enhances the accuracy of the method.
