Abstract: L'invention concerne un système et un procédé, selon lesquels plusieurs dispositifs de télétransmission communiquent de manière asynchrone avec une ou plusieurs stations réceptrices. Les émetteurs sont des unités relativement peu onéreuses qui font appel à des circuits de base de temps également peu onéreux pour produire un signal chirp codé par position d'impulsions et utilisé pour moduler un signal de porteuse. Après réception du signal au niveau des stations réceptrices, le signal peut être démodulé et décodé au moyen d'un signal chirp de référence qui a été localement produit de manière asynchrone par rapport à la base de temps de n'importe quel émetteur. Au moyen d'un filtre adapté ne variant pas dans le temps, la station réceptrice obtient le moment d'arrivée des différents signaux transmis et toutes données supplémentaires.

Title: Method and apparatus for releasing functional units in a multithreaded vliw processor
Inventor: JEREMIASSEN TOR E
IPC: G06F9/38
Filed: 2001-02-26
Abstract: A method and apparatus are disclosed for releasing functional units in a multithreaded very large instruction word (VLIW) processor. The functional unit release mechanism can retrieve the capacity lost due to multiple cycle instructions.  The functional unit release mechanism of the present invention permits idle functional units to be reallocated to other threads, thereby improving workload efficiency.  Instruction packets are assigned to functional units, which can maintain their state, independent of the issue logic. Each functional unit has an associated state machine (SM) that keeps track of the number of cycles that the functional unit will be occupied by a multiple-cycle instruction. Functional units do not reassign themselves as long as the functional unit is busy. When the instruction is complete, the functional unit can participate in functional unit allocation, even if other functional units assigned to the same thread are still busy.   The functional unit release approach of the present invention allows the functional units that are not associated with a multiple-cycle instruction to be allocated to other threads while the blocked thread is waiting, thereby improving throughput of the multithreaded VLIW processor. Since the state is associated with each functional unit separately from the instruction issue unit, the functional units can be assigned to threads independently of the state of any one thread and its constituent instructions.
Patent CA-2338554-A1 (CA)
Inventor: BUTTERFIELD ROBERT D
IPC: F04B43/08
Filed: 1999-07-29
Abstract: A system for increasing the volumetric flow uniformity of fluid pumped through a conduit by an infusion pump. A pumping mechanism operates in identifiable step movements that are broken down into microstep movements that are then grouped into packets. The pumping mechanism controls the period of each microstep, so that the sum of the microstep periods in a packet is essentially equal to the packet period, with little or no waiting time on the motor. The motor preferably begins moving the assigned microsteps in each packet immediately upon the beginning of the time period, but controls the period of the microsteps for that packet.

Title: Apparatus and methods relating to humidified air and to olfactory monitoring
Inventor: VASS STEVEN GEORGE
IPC: G01N33/00
Filed: 1999-11-09
Abstract: Apparatus (10) is shown for providing a flow of humidified air at a selected  humidity level, and a method is disclosed of monitoring olfactory parameters  of a sample gas or vapour to provide a "finger print" or profile of an odour . The flow of humidified air is used to set a level of humidity in a sensor chamber (36) which is the same as the level of humidity in a sample chamber (44) containing the sample of gas or vapour. The sample gas or vapour is the n introduced into the sensor chamber (36), where an array of olfactory sensors  record the odour profile, without a sudden change of humidity level when the  sample gas or vapour is admitted. The flow of humidified air at a selected humidity level is obtained from a generator (10) having a controllable valve  (14) for directing a clean dry air stream along either of two paths (17, 18) , one of which includes a humidifier (22). Air from the two paths is combined in a mixing chamber (21) and the humidity level is monitored by a sensor (23) with a feedback loop to control the valve (14). Sensors other than olfactory  sensors, e.g. infrared sensors, may be used.

Inventor: HORN WILLIAM P
IPC: G06T15/04
Filed: 2001-09-28
Abstract: A computer system and method for simplifying annotations on a surface includes a tolerance process creating a tolerance window lying in a plane and centered on the query point at the end of a test edge and perpendicular to the test edge. The tolerance window is defined by a first tolerance that specifies an amount of first error measured by the distance from a simplified path to an original path in the plane tangent to the surface, and a second tolerance that specifies an amount of second error measured by the distance from the simplified path to the original path in the plane perpendicular to the surface. The original path is a set of original edges on the surface. A point projection process that projects a second end point of one or more second edges onto the plane of the tolerance window. The second edges have the query point also as an end point where the projection of the second end points are projected points. An invalidation process marks an edge as "invalid" and removes it both from the list of simplifiable edges and the final list of simplified edges. A selection process selects one of the second end points that has a projected point within the plane containing the tolerance window, deletes the query point, and connects the origin point to the respective second end point, to create a new edge that replaces the test edge and respective second edges in the set of original edges to create the simplified path.
