Filed: 1996-06-06
Abstract: A multiprocessor system includes a number of sub-processor systems, each substantially identically constructed, and each comprising a central processing unit (CPU), and at least one I/O device, interconnected by routing apparatus that also interconnects the sub-processor systems.  A CPU of any one of the sub-processor systems may communicate, through the routing elements, with any I/O device of the system, or with any CPU of the system.          Communications between I/O devices and CPUs is by packetized messages.  Interrupts from I/O devices are communicated from the I/O devices to the CPUs (or from one CPU to another CPU) as message packets.          CPUs and I/O devices may write to, or read from, memory of a CPU of the system.  Memory protection is provided by an access validation method maintained by each CPU in which CPUs and/or I/O devices are provided with a validation to read/write memory of that CPU, without which memory access is denied.

Title: Work at home agent acd call distribution
Inventor: SAND PAUL RAYMOND
IPC: H04M3/523
Filed: 1994-06-15
Abstract: An arrangement for providing Automatic Call Distribution (ACD) service from a mixture of local and remote agents. The remote agents (3) are connected via a voice connection to the home switch of the ACD and voice data connection to a Home Agent Server HAS (6). The HAS (6) passes call event data to Management Information System MIS (8) of the ACD, which informs the ACD switch (1) of call events that make a remote agent available or unavailable, and passes application data to a host processor for serving the applications of the ACD. Call set-up time is reduced by establishing longer term connections between the ACD and the remote server and using these connections for a plurality of calls, such connections are established or disconnected when the traffic level suggests the desirability of having more or fewer remote servers. Advantageously, ACD service can be provided efficiently and economically from a remote server.

Inventor: BARKER DONALD
IPC: B41J11/00
Filed: 1996-10-22
Abstract: A method for creating anti-aliased characters on a computer output device includes the steps of generating a call from a client process for a character to be rendered, rendering the character at a high resolution, and aligning stems of the character with a coarse grid corresponding to the resolution of an output device. The step of aligning the high resolution rendered stems to the coarse grid provides for an anti-aliased output with balanced stems. A method for rendering a character includes the steps of determining a device resolution and a number of greyscales to be displayed by a digital output device, determining a coarse grid and a high-resolution grid, developing character information concerning a character to be rendered, creating an initial bitmap of the character from the character information at the resolution of the high-resolution grid, and aligning stems of the initial bitmap with the coarse grid to create a coarse grid aligned high-resolution bitmap.

Title: Method and reagents for the treatment of rheumatoid arthritis
Inventor: CARSON DENNIS A
IPC: A61K35/74
Filed: 1995-04-24
Abstract: Methods useful in the treatment or prevention of rheumatoid arthritis (RA) are disclosed.

Patent CA-2192279-A1 (CA)
Title: Multipurpose knife with gut hook
Inventor: JEFFCOAT NORMAN C
IPC: B26B27/00
Filed: 1996-12-06
Abstract: An ergonomically-designed, multipurpose knife having a handle, a blade with a shank and a tip, and a fastener for attaching the handle to the shank. The blade has a curved outer edge extending substantially from the shank to the tip, with an integrally-formed gut hook positioned near the shank and opening toward the tip. A portion of the outer edge is sharpened to form a cutting edge. The fastener is user-operable for moving the blade from a first operating position where it opposes the handle to a second operating position where it extends forward of the handle for use as a hatchet. In the first position, force exerted on the handle and directed toward the blade is distributed approximately uniformly along the entire length of the outer cutting edge. Skinning cuts are made by grasping the handle and pivoting the wrist to produce controlled strokes approximately in the plane of the blade; chopping and slicing cuts are made by pivoting the wrist to rock the knife about an axis transverse to the plane of the blade. The user can control the length and direction of a cut by pivoting the wrist alone, the forearm at the elbow, the entire arm from the hand gripping the knife to the shoulder, or by pushing or pulling the knife with the hand and forearm, or any combination thereof. Range of motion, dexterity and control of the cutting edge are thereby improved, with greater comfort than is possible with a conventional knife.

The flow control device further may include a control circuit in the production string for controlling the operation of the electrically-operated device. The control circuit may communicate with the a surface control unit preferably a computer-based system which may provide commands to the downhole control circuit for causing the electrically-operated device to adjust the position of the sleeve. The sleeve may be positioned at any place on the labyrinth, providing accurate control over the flow rate. The surface control unit may communicate with the downhole control circuit via a data communication link which may be a cable or a trans/receiver system. 1.
