Patent CA-2261084-A1 (CA)
Title: A data processing system having an apparatus for exception tracking during out-of-order operation and method therefor
Inventor: NGUYEN DOUG Q
IPC: G06F9/38
Filed: 1999-02-01
Abstract: An apparatus for integer exception register (XER) renaming and methods of using the same are implemented. In a central processing unit (CPU) having a pipelined architecture, integer instructions that use or update the XER may be executed out-of-order using the XER renaming mechanism. Any instruction that updates the XER has an associated instruction identifier (IID) stored in a register. Subsequent instructions that use data in the XER use the stored IID to determine when the XER data has been updated by the execution of the instruction corresponding to the stored IID. As each instruction that updates XER data is executed, the data is stored in an XER rename buffer.  Instructions using XER data then obtain the updated, valid, XER data from the rename buffer. In this way, these instructions can obtain valid XER data prior to completion of the preceding instructions. The XER data is retrieved from the XER rename buffer by indexing into the buffer by using an index derived from the stored IID. Because the updated XER  data is available in the rename buffer before the updating instruction completes, out-of-order execution of instructions using or updating XER data is thereby realized.

Patent CA-2276244-A1 (CA)
Inventor: DENO DON CURTIS
IPC: A61N1/37
Filed: 1997-10-31
Abstract: A pacemaker (100) is disclosed that includes circuitry (175) for monitoring the current and/or voltage delivered to the heart during a pacing pulse. A  microprocessor (225) connects to the monitoring circuitry and analyzes the current (and/or voltage) to determine when capture occurs. When capture occurs, the microprocessor terminates the pacing pulse to save energy.  Conversely, if capture does not occur within a predetermined maximum time period, or if the pacing pulse amplitude falls below a predetermined threshold value, the processor immediately causes a safety pulse to fire to insure a regular beating of the heart. By monitoring the current and/or voltage delivered, and by permitting the pacing pulse width to be variable, the pacemaker of the present invention can closely track the pacing threshold of the patient with a minimum expenditure of energy.

Abstract: La présente invention concerne un procédé et un appareil permettant de former une longueur de ressorts à boudin enfermés dans des poches et reliés entre eux, destinés à des matelas et analogues. Selon ledit procédé, on chauffe (16), avant de l'enrouler, le fil (10) provenant d'une source de distribution à une température comprise entre 450 et 500 degrés Fahrenheit à l'aide d'un appareil chauffant à induction. Ensuite, le fil est enroulé à chaud (18), coupé (20), et refroidi (22) à une température inférieure à la température à laquelle une déformation permanente pourrait survenir lors du traitement ultérieur du ressort. On comprime (24) ensuite le ressort pour le préparer à être inséré (26) dans un espace aménagé dans de la toile extensible provenant d'une bobine débitrice. On replie (14) la toile (12) sur elle-même pour ménager cet espace. La température du ressort doit être assez basse pour que le ressort puisse entrer en contact avec la toile sans la brûler ou l'endommager. Après avoir inséré le ressort comprimé dans l'espace, on soude la toile par ultrasons (28) afin de créer des poches individuelles mais reliées entre elles pour chaque ressort. Enfin, on oriente (30) les ressorts afin que chacun d'eux puisse s'étendre et, ce faisant, on crée la longueur de ressorts à boudin enfermés dans des poches et reliés entre eux.
