Patent CA-2144738-A1 (CA)
Title: A subpopulation of mac-1 (cd11b/cd18) molecules which mediate neutrophil adhesion to icam-1 and fibrinogen
Inventor: DIAMOND MICHAEL
IPC: C07K16/28
Filed: 1993-10-12
Abstract: The present invention is based on the novel observation that upon stimulation of resting myeloid cells, not all of the Mac-1 molecules expressed by the cell become activate. Only select subpopulations of Mac-1 molecules are activated and become cap-able of binding ligand. Further, the activated Mac-1 molecules were found to possess activation specific epitopes which distin-guishes them from non-activated Mac-1 molecules. Based on these observations antibodies are described  which selectively bind activated Mac-1 molecules but are substantially incapable of binding non-activated Mac-1.

Patent CA-2150218-A1 (CA)
Title: Dual stage approach for evaluating a received signal in a communications system
Inventor: MECHE PAUL S
IPC: H04W36/08
Filed: 1995-05-25
Abstract: A long term average and a short term value of the strength of a received signal is used to determine a trigger condition in a mobile communications system to perform such functions as control channel or traffic channel reselect.   The long term average removes the effects of short term fades in the short term signal that otherwise may cause a premature trigger decision.  The short term value offsets historical bias that may be built into long term average. The actual trigger is only realized when both the long term average and the short term value exceed predetermined thresholds in a positive or negative direction.

Patent CA-2162618-A1 (CA)
Title: System for, and method of, processing in hardware commands received from software without polling of the hardware by the software
Inventor: BAKER DAVID C
IPC: G06T11/00
Filed: 1995-11-10
Abstract: A CPU introduces software commands to a first limited capacity memory (e.g. FIFO), on an integrated circuit chip.  Data (e.g. graphics) from a first portion of a second memory (off chip) is processed in accordance with such commands.  A second portion (e.g. FIFO) of the second memory may also store commands normally passing from the CPU through the first memory.  When the first memory becomes full, the commands may pass from the CPU through the second portion of the second memory (which may have a storage capacity considerably greater than that of the first memory) and then through the first memory.  The commands may continue to flow in this auxiliary path until the second portion of the second memory becomes empty.  A third memory of a limited capacity on the chip may pass the commands from the CPU to the first memory in the normal operation or to the second portion of the second memory when the first memory becomes full.  The CPU may also pass commands to other peripheral equipment while a ready line is high.  When low, the ready line prevents commands from passing to the peripheral equipment while the third memory is full. However, a command may pass from the third memory to the first or second memory to make the ready line high.  A counter indicates the number of commands in the first and third memories and the second portion of the second memory. Software occasionally interrogates the counter to update in the software the number of commands in the counter.

Patent CA-2173907-A1 (CA)
Title: System for setting date wheels in a postage meter
Inventor: NAST KURT
IPC: G07B17/00
Filed: 1996-04-11
Abstract: In a postage meter that has value wheels and date wheels, each value wheel is adjustable by a linkage that moves through a range of positions sufficient to select any of the ten print indicia thereof.  Several of the linkages (enough for the date wheels that need setting) are able to move further (to what might be termed an "eleventh position"), beyond the positions for the ten indicia of the value wheels.  When such a linkage moves to its eleventh position, it moves a pawl that ratchets a corresponding date wheel to its next position.  The linkages may include rack elements that move along the axis of the print rotor.  Each such rack element has a first rack that is engagable with a gear in the main body of the postage meter (when the rotor is in its "home" position) and a second rack that engages with a value wheel.  The engagement between the rack element and the value wheel defines ten linear positions for the rack element, one for each of the digits printable by the value wheel.  An eleventh position of the rack element causes the rack element to push a lever, and the lever causes the pawl to move a date wheel to its next position.  A "closed loop" method of operation permits the postage meter, with the assistance of the user, to accomplish recovery from an incorrect date wheel position.     For each of several settable date wheels on a common axle, there is provided an advancing mechanism disposed to advance its corresponding date wheel by one or more positions.  Importantly, the several advancing mechanisms are disposed so that relative to the axle, one means advances its date wheel clockwise, the next counterclockwise, and so on in alternation.  Since each advancing means not only serves to advance its corresponding date wheel in a predetermined direction but also serves to block its corresponding date wheel from retrograde rotation, it is not possible for a wheel that is being advanced to drag along its neighbor.
