Title: Interrupt-driven processor system.
Inventor: HENRY MICHAEL DAVID
IPC: G06F15/78
Filed: 1993-06-15
Abstract: An interrupt-driven processor system comprising a processor 10 connected via a plurality of processor input and output lines to an input means 20 in the form of a keypad or keyboard. Actuation of one of the keys of the input means generates an interrupt signal on one of the input lines which invokes an interrupt service routine in the processor. In accordance with the invention, a secondary interrupt source can be attached to each of the input lines with the interrupt service routine being designed to discriminate between an interrupt signal generated by actuation of a key and an interrupt signal generated by a secondary source. Using this technique, further interrupts can be added to an off-the-shelf processor including keypad interrupts without the need for additional interrupt controlling hardware. Furthermore, a custom-built microprocessor can be designed with fewer interrupt pins. <IMAGE>

Patent GB-2278524-A (GB)
Title: Method and apparatus for rendering visual images employing area calculation and blending of fractional pixel lists for anti-aliasing and transparency
Inventor: KUCHKUDA ROMAN
IPC: G06T15/50
Filed: 1994-03-30
Abstract: A system for rendering visual images that combines sophisticated anti-aliasing and pixel blending techniques with control pipelining in hardware embodiment. A highly-parallel rendering pipeline performs sophisticated polygon edge interpolation, pixel blending and anti-aliasing rendering operations in hardware. Primitive polygons are transformed to subpixel coordinates and then sliced and diced to create "pixlink" elements mapped to each pixel. An oversized frame buffer memory allows the storage of many pixlinks for each pixel. Z-sorting is avoided through the use of a linked-list data object for each pixlink vector in a pixel stack. Because all image data values for X, Y, Z, R, G, B and pixel coverage A are maintained in the pixlink data object, sophisticated blending operations are possible for anti-aliasing and transparency. Data parallelism in the rendering pipeline overcomes the processor efficiency problem arising from the computation-intensive rendering algorithms used in the system of this invention. Single state machine control is made possible through linked data/control pipelining. <IMAGE>

Title: A linkage controlled spring powered feed system for maintaining a constant force against a linearly movable member
Inventor: CLOUTIER DANIEL R
IPC: B24B33/02
Filed: 1994-04-13
Abstract: The system includes a lever member 22 having one end which bears against the linearly movable member 28 and an opposite end, the lever member being pivotally mounted at a location 24 between the opposite ends thereof on the machine frame, a linkage assembly bearing against the opposite end of the lever member in a direction to apply force against the linearly movable feed member, the linkage assembly including a first expandable link member 34 having a compression spring for exerting force against the lever member and a second link member 48 for adjusting the position where the linkage assembly engages the lever member as the lever member moves about the pivotal support to change the effectiveness of the compression spring in applying force to the linearly movable member. The system can optionally include an additional linkage enabling selective adjustment of the level of constant force to be applied against the linearly movable member, and one or more cam members and spring members enabling speed control, counteracting and otherwise affecting the force applied against the linearly movable member. The system is preferably used to control the feed force on a working member such as a honing stone in a honing machine. <IMAGE>

Title: Torque controlled continuously-variable-ratio transmission of the band-and-sheave type has torque sensitive connection to pulley tending to separate sheaves
Inventor: FELLOWS THOMAS GEORGE
IPC: F16H37/02
Filed: 1994-12-09
Abstract: A continuously-variable-ratio transmission ("CVT") of the band-and-sheave type capable of "torque control", so that what the operator demands, by movement of the accelerator pedal or other control member, is a particular driving torque applied to the ratio varying component ("variator"). A connection (21, 22) between at least one of the variator sheaves (3, 4) and its shaft (5) is torque-sensitive, so that torque at that sheave generates an axial force which is a function of the magnitude and direction of the torque to which the sheave is subjected. The sheave assemblies are also preferably loaded hydraulically. The torque-sensitive connections (21, 22) preferably have a ball and screw action. Both sheaves or only one sheave of a pulley may have torque-sensitive connections (21, 22) of opposite hand, the non-torque-sensitive connection being an axially movable connection when only one connection is torque-sensitive. As one of the pulleys has the torque-sensitive connections, the other should have simple axial connection for both sheaves. <IMAGE>

Title: Inflatable packer or bridge plug
Inventor: APPLETON ROBERT PATRICK
IPC: E21B33/127
Filed: 1994-12-09
Abstract: A downhole inflatable packer or bridge plug has a mandrel 1 through which it is possible to circulate drilling fluid or gas, the packer also comprising a cylindrical elastomer element 2. The element 2 can be inflated by surface pump pressure to form a pack-off or bridge-plug in either cased or open hole well bore. The packer is inflated via ports 5 in the mandrel 1 after a pump down dart 6 is locked into the packer preventing further circulation through the body. After the packer has been fully inflated a further increase in pressure causes a shear out sleeve 7 to move downwards. This action releases the packer from the tubing conveying string, the dart 6 becoming locked in the mandrel 1 to maintain the pressure in packer by a check valve. <IMAGE>

Title: Target detection
Inventor: LINTOTT PETER
IPC: G01S7/41
Filed: 1995-04-11
Abstract: A method of target detection in a system employing range cells includes the steps of;  (i) comparing 3 the received signal power level of each cell with a first threshold and categorising some of the cells as possibly containing real target returns, (ii) processing 1 the received signal power levels of each cell possibly containing a real target return to correct for non-uniformity of response across the cells, and (iii) comparing 6 the corrected received signal power levels to a second threshold and categorising those cells having a corrected signal power level above the second threshold as containing real target returns and those having a corrected signal power level below the second threshold as not containing real target returns. The double threshold approach enables fewer false alarm responses while maintaining a low level signal detection capability. This is especially useful in skywave over-the-horizon radar. Prevents "scalloping".

Title: Emulation system for microprocessors
Inventor: YUI H L
IPC: G06F11/36
Filed: 1997-11-17
Abstract: An emulator system for generating a breakpoint to a microprocessor has an internal address comparator (3) for internally comparing at least a part of a chosen breakpoint address, a bi-directional port (EMUBRK) for connection to external emulation circuitry and a breakpoint generator (2). The system supports (i) the generation of a single breakpoint by internally matching the whole of the chosen address, and (ii) the generation of multiple breakpoints by internally matching only part of the chosen address and detecting a match signal from external emulation circuitry indicating an external match of the remaining part of the chosen address. The emulation system is thus sufficiently simple to be integrated with a microprocessor while minimizing the pin count required for interfacing to external emulation circuitry.
