Patent CA-2332085-A1 (CA)
Inventor: STOODLEY KEVIN ALEXANDER
IPC: G06F9/48
Filed: 2001-01-23
Abstract: A method and computer system that implements polymorphic inline caches having locking slots. Of a polymorphic dispatch, each time the polymorphic method is called having a new object type, a new slot in the polymorphic inline cache is created. By comparing the object types of new methods with object type values already in the cache, it can readily be determined if a new slot has to be created to accommodate a new object type. Preferably, if two threads wish to access the polymorphic inline cache at the same time, the second thread will wait until the first thread accesses and creates and/or uses its slot because it is likely that the second thread will call the method of the same type. Alternatively, however, the second thread may access and create and/or use another slot of the polymorphic inline cache because the first slot is locked to all objects other than its type. If the threads wish to access the same slot of the polymorphic inline cache, then the first thread may lock and modify the slot to call the method while the second thread may just call the method without modifying the slot. A just-in-time compiler may be used to create the polymorphic inline cache described within, but once created, the polymorphic cache may be exported to and used in other computer systems not having a just-in-time compiler including embedded devices such as mobile computing devices.

Filed: 1999-11-16
Abstract: Selon l'invention, un signal acoustique désiré est extrait d'un environnement bruyant par génération d'un signal représentant le signal désiré, à l'aide d'un processeur (30). Le processeur (30) reçoit des signaux sonores de deux capteurs (22, 24) situés chacun à un emplacement différent. Les deux entrées reçues par le processeur (30) sont converties du format analogique au format numérique, puis soumises à une transformée de Fourier discrète en vue de générer des représentations de signaux spectraux discrets. Les signaux spectraux sont retardés pour faire passer un certain nombre de signaux intermédiaires correspondant chacun à un emplacement spatial diffférent relativement aux deux capteurs. Les emplacements de la source de bruit et de la source désirée et le contenu spectral du signal désiré sont déterminés à partir du signal intermédiaire correspondant aux emplacements de la source de bruit. Une transformée inverse du signal intermédiaire choisi, suivie d'une conversion numérique-analogique, produit un signal de sortie représentant le signal désiré, grâce à une unité de sortie (90). L'invention concerne également des techniques permettant de localiser de multiples sources acoustiques. Elle concerne en outre une technique pouvant améliorer la réduction du bruit dans de multiples sources, sur la base d'une réception mettant en oeuvre deux capteurs.

Filed: 2000-03-08
Abstract: The present invention relates to the use of xenon or xenon gas mixtures for treating neurointoxiations. In particular, the present invention is directed to such a xenon use in which the neurointoxiation is caused by a neurotransmitter excess. Xenon can reduce the release of neurotransmitters, particularly dopamine, which are caused e.g. by hypoxic situations such as an apoplexy or a craniocerebral trauma. A  preparation containing xenon can also be used as therapeutic agent in the case of depressions, schizophrenia and Parkinson's disease, in which the neurotransmitter equilibrium is also disturbed. The application by inhalation is simple and the harmlessness of xenon has already been proved by its use as anesthetic agent.
Patent CA-2367325-A1 (CA)
Title: Broadband sagnac raman amplifiers and cascade lasers
Inventor: ISLAM MOHAMMED NAZRUL
IPC: H01S3/094
Filed: 1999-03-31
Abstract: This invention describes new developments in Sagnac Raman amplifiers (20) an d cascade lasers to improve their performance. The Raman amplifier bandwidth i s broadened by using a broadband pump (26, 150) or by combining a cladding- pumped fiber laser (100) with the Sagnac Raman cavity. The broader bandwidth  is also obtained by eliminating the need for polarization controllers in the  Sagnac cavity by using an all polarization maintaining configuration, or at least using loop mirrors (22, 24) that maintain polarization. The polarizati on maintaining cavities have the added benefit of being environmentally stable and appropriate for turn-key operation. The noise arising from sources such as double Rayleigh scattering is reduced by using the Sagnac cavity (22, 24) in  combination with a polarization diversity pumping scheme, where the pump is split along two axes of the fiber. This also leads to gain for the signal th at is independent of the signal polarization. Finally, a two-wavelength amplifi er for 1310 nm and 1550 nm can be implemented by using a parallel combination o f Raman amplifiers with shared pump lasers or by combining Raman amplifiers (2 0) with erbium-doped fiber (30) amplifiers. Combinations of the above improvements can be used advantageously to meet specifications for broad bandwidth, polarization independence, noise performance and multi-wavelength  operation.
