Title: Method for computer program optimization in a dynamic compiling environment
Inventor: SHEIKH ALI I
IPC: G06F9/45
Filed: 2003-09-26
Abstract: Dynamically compiled computer program code containing virtual calls can reduce the options for optimization during compilation. A virtual call can affect sections of the program code that are compiled subsequent to the virtual call. Therefore, the state under which the effected sections are to be executed may not be known at the time of compilation thus complicating optimization of these sections. If assumptions are made about the state of an effected section, then this section can be optimized. In order to provide proper operation of the executing program code given the optimization, a check of the validity of the assumptions is performed prior to execution of the optimized section. If an assumption does not hold true then the original un-optimized section can be executed to reduce adverse program performance.

Inventor: LANDRIAU SYLVAIN
IPC: G09B25/04
Filed: 2003-10-09
Abstract: Lors de la planification de la disposition des équipements d'une entreprise, divers outils permettent l'établissement d'une synergie logistique. Toutefois, ces outils utilisés individuellement ne favorisent pas une visualisation concrète de l'ensemble de l'espace utilisable et une compréhension rapide de l'environnement. La visualisation du résultat escompté devient donc pratiquement inaccessible à la majorité des intervenants. En ce sens, de par sa maniabilité et sa staticité, notre maquette se veut une invention innovatrice. Offrant aux intervenants une vue d'ensemble de l'entreprise, cet outil, accessible à tous, réduit considérablement le temps de conception et les erreurs de faisabilité liées à l'aménagement, tout en permettant une meilleure communication entre les responsables du projet au sein de l'entreprise. La maquette reproduit fidèlement chaque équipement, que ce soit machinerie ou modules de bureau, ainsi que l'espace plancher des différentes aires de travail. Toutes les composantes de la maquette s'assemblent par magnétisme, permettant ainsi une flexibilité et une durabilité totales.

Title: Ink jet recording apparatus utilizing solid semiconductor element
Inventor: YAMAGUCHI TAKAAKI
IPC: B41J2/01
Filed: 2001-06-13
Abstract: To supply electromotive force to a solid semiconductor element in an ink tank. in a non-contact and stable manner. An electromagnetic apparatus (a standstill electromotive force supply unit) is placed at a home position HP. When a carriage is at a standstill at this home position HP, if the electromagnetic apparatus is AC-driven, magnetic properties of both ends (magnetic poles) continue to change mutually and penetrate a solid semiconductor element in the ink tank on the carriage so that a constantly changing magnetic flux is generated.      Electromotive force is generated by electromagnetic induction on a coil of the solid semiconductor element.      In addition, if tie carriage reciprocates during printing operation, the coil L of the solid semiconductor element crosses inside the magnetic flux due to a plurality of permanent magnets (a movement time electromotive force supply unit) arranged on a carrier path (range of movement), and so the electromotive force is generated on the coil by electromagnetic induction. Such electromotive force is converted into energy for activating and operating the solid semiconductor element.

Title: Gas turbine engine broken shaft detection system
Inventor: JONES KEVIN A
IPC: F01D21/04
Filed: 2002-11-12
Abstract: The broken shaft detection system and method uses a detector assembly mounted downstream of a power turbine wheel of a gas turbine engine to detect rearward axial motion of the wheel and thereby a broken shaft event. The detector assembly has a plunger positioned to be axially displaced against a link connected in an electrical circuit. The link may be broken when the plunger is displaced thereby creating an open circuit that may be detected by a detection and test element. The breaking may be communicated to an overspeed circuit that controls a shut off switch that interrupts fuel flow to the engine. The link may be connected to the detection and test element by two pairs of parallels wires to facilitate monitoring of circuit function and to detect failures that are not broken shaft event failures.
