Title: Filtering method for reducing blocking effect and ringing noise of image data
Inventor: LEE YUNG-LYUL
IPC: H04N19/625
Filed: 1997-10-23
Abstract: A gradient of image data is calculated for each pixel of the image data (410) and is compared with a global threshold value (T g ) which is determined based on a predetermined quantization step (420). The gradient data of each pixel is compared with a local threshold value (T n ) which is determined for each block having a predetermined size, (430). An OR operation is performed (440) with respect to the global edge map information and the local edge map information to generate binary edge map information (450). A filter window of a predetermined size is applied to determine whether edges are present (460). The pixel values of the corresponding filter window are filtered pixel by pixel by using predetermined first weighted values to generate a new pixel value if it is determined that edges are not present (485). The pixel values of the corresponding filter window are filtered pixel by pixel by using predetermined second weighted values to generate a new pixel value if it is determined that edges are present (480), while the filtering is not performed if the pixel located at the center of the filter window represents an edge (475).

Patent GB-2333921-A (GB)
Title: Non-symmetric radial and non-symmetric pruned radial interpolation
Inventor: VONDRAN JR GARY L
IPC: H04N1/60
Filed: 1998-12-08
Abstract: New interpolation techniques allow improved efficiency and speed in performing color space conversions. A radial interpolation technique (FIG. 7-8) accomplishes an interpolation by generating successive sub-cubes (FIG. 6a-6e). A value of a vertex of the final sub-cube generated is used as the result of the interpolation. Sub-cubes (FIG. 6a-6e) are generated by averaging (FIG. 5) a selected vertex value with the vertex values of each of the remaining vertices. A pruned radial interpolation technique (FIG. 9-12, FIG. 38-39) employs a subset of the vertex values of the initially selected cube to generate the result of the interpolation, thereby improving upon the efficiency of the radial interpolation. A tetrahedral interpolation technique (FIG. 16-17) accomplishes an interpolation by generating successive sub-cubes (FIG. 14). A value of a vertex of the final sub-cube generated is used as the result of the interpolation. Sub-cubes are generated by applying a mathematical relationship which allows computation of sub-cube vertex values through a series of logical AND, logical OR and averaging operations. A pruned tetrahedral interpolation technique (FIG. 15-16, FIG. 18-20, FIG. 40-41) employs a subset of the vertex values of the initially selected cube to generate the result of the interpolation, thereby improving upon the efficiency of the tetrahedral interpolation. A common hardware implementation (FIG. 21-22) of pruned radial interpolation (FIG. 9-12, FIG. 38-39) and pruned tetrahedral interpolation (FIG. 15-16, FIG. 18-20, FIG. 40-41) uses the common hardware structure of the two techniques with multiplexing of the input vertex values to allow performance of either a pruned radial interpolation (FIG. 9-12, FIG. 38-39) or a pruned tetrahedral interpolation (FIG. 15-16, FIG. 18-20, FIG. 40-41).

Title: Coaxial loudspeaker with the magnetic circuit mounted in front of the diaphragm
Inventor: POCOCK NICHOLAS
IPC: H04R9/02
Filed: 1999-12-17
Abstract: An inverted coaxial speaker 100 for use in automobile doors and similar thin structures has both its bass and tweeter components essentially located within the frustoconical outline of the bass speaker cone. A generally planar webbed structural member 104,204 extends across the larger end of the speaker cone, and centrally supports a magnetic structure 106,250 housing a coil for driving the speaker cone. A tweeter structure 132 is mounted on the magnetic structure and takes one of two forms. In a first form of the speaker, the magnetic structure has an axial channel 142 and the tweeter structure is mounted at the rear of the channel and sends sound through the channel; the tweeter has a conductive skirt 138 that is inductively coupled to the coil. In a second form of the speaker, the magnetic structure has no axial channel but does have a frontal depression 260 into which the tweeter structure is fitted; the tweeter structure has a tweeter voice coil 270 instead of being inductively-coupled. In both forms of the speaker, sound above about 4KHz leaves from a central region of the webbed structural member, and lower-frequency sound leaves from an annular region surrounding the central region.
Patent GB-996660-A (GB)
Abstract: 996, 660. Knitting machines. WIRKMASCHINENBAU KARL-MARX-STADT VEB. March 18, 1964, No. 11443/64. Heading D1C. A movable cutting tool holder 11 in a circular knitting machine is lockable in either operative or inoperative position by the positioning of a stop element 19 connected to the cutting tool holder in front of or behind an element 22 on a controllable bolt 21 which is locked in position by the action of a needle lowering element 2. The cutting tool holder 11 is urged towards its inoperative position by a spring 13 and held there as described above. A lever 25 is pivoted at 24 and is moved by the radial movement of the lowerer 2 acting against a bolt 27, the lowerer 2 being operated by a bell crank lever 6 operated by a rod 7 operated from the main cam drum; this lever has a nose 26 which prevents downward movement of the bolt 21 when the lowerer 2 is in its inoperative position as is the cutting tool holder 11. The cutting tool holder 11 is returned to its operative position against the action of spring 13 by a lever 14 operated by a Bowden cable 15, 16 from the main cam drum 18. The cable sheath contains a compression spring 31 which acts as a flexible drive insofar as it retains the movement imparted to the inner wire of the Bowden cable until the cutting tool holder is unlocked from its inoperative position. The compression in the spring then turns the lever 14 to return the cutting tool holder 11 to its operative position. The movable bolt 21 is pulled down by the armature 33 of an electromagnet 32 and returned by a spring 23.
