Patent CA-2258656-A1 (CA)
Title: A phase detector
Inventor: POPPLEWELL Andrew
IPC: H04L7/033
Filed: 1999-01-07
Abstract: A phase detector determines a phase error value dependent on the relative phase between a local oscillator signal, used for the system clock, and an input signal received over a PR (a, b, b, a) channel. The error value is used to lock the phase and frequency of an input signal to the phase and frequency of the clock in a phase-lock loop (Figure 1, not shown). The input signal is sampled at regular intervals in accordance with the local oscillator signal, and the sampled values provided on a line 10. A threshold dicer 22 selects an ideal sample value for a sampling point by comparing the sampled values with thresholds received on threshold inputs 23 to 26. A subtracter 32 determines a difference value which corresponds to a difference between the ideal sample value and the actual sample value for that sampling point. A subtracter 28 and a delay register 29 operate to determine the sense of change to the ideal sample value from a ideal sample value for a preceding sampling point. A second subtracter 42 and a second delay register determine the sense of change to the ideal sample value for a preceding sampling point from a ideal sample value for a twice preceding sampling point. The phase error value provided is dependent on the senses of change detected and on the difference value.

Patent CA-2264355-A1 (CA)
Inventor: GREENE JEREMIAN
IPC: F25B21/02
Filed: 1999-03-01
Abstract: A solid-state cooling device for cooling liquid, for example water, having an external heat dissipater and a probe-like cooling element for insertion through a hole formed in the top or side of a reservoir or the wall of a water pipe so that the device can be installed and continuous cooling effected. The probe-like cooling element is slightly tapered at the base where a grommet-like collar is seated. A hole specific to the size of the collar is first made in the wall, top or side of a liquid container and then the probe and collar are manually inserted into the hole so that the cooling probe is inside the liquid container and in direct contact with the fluid therein. In this manner the device can be quickly installed even into a container of fluid or a water line with a minimum of spillage. The taper at the base of the probe expands the collar in the hole causing a self sealing effect and preventing continuous leakage while permitting cooling of the liquid contained therein.

Inventor: MARTIN ERIC D
IPC: B01J19/28
Filed: 1999-04-08
Abstract: A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to both low- and high-flux photoreactor design and scale-up. The low-flux method is based on the implementation of natural biopolymeric and other low-pressure drop media support for titanium dioxide and other band-gap photocatalysts. The high-flux method is based on the implementation of multifunctional metal oxide aerogels and other media in conjunction with a novel rotating fluidized particle bed reactor.

Title: Methods for promoting wound healing and treating transplant-associated vasculopathy
Inventor: SHEARS LARRY L II
IPC: C12N9/06
Filed: 1997-11-07
Abstract: The present invention provides a method of promoting the closure of a wound in a patient. This method involves transferring exogenous iNOS to the region of the wound whereby a product of iNOS is produced in the region of the wound to promote the closure of the wound. The present invention also provides a method of transplanting a graft into a patient, which method involves transferring a vector comprising an iNOS expression cassette to cells associated with the graft and surgically incorporating the graft tissue into the patient. Upon expression of iNOS within the patient, a product of iNOS is produced in the region of the graft to attenuate vasculopathy in the region of the graft. To effectuate the inventive methods, the invention also provides pharmaceutical compositions for supplying iNOS and/or BH4 to cells associated with wounds or grafts.

Title: Techniques de stockage et de remplacement de memoire cache fondees sur la penalite
Inventor: LIEDBERG PER
IPC: G06F12/12
Filed: 1998-03-13
Abstract: Des techniques de remplacement de données de mémoire cache permettent d'améliorer la performance dans un système d'ordinateur comprenant une unité centrale de traitement (UCT), une mémoire cache et une mémoire principale, la mémoire cache comportant une pluralité de données élémentaires stockées dans cette dernière. Les techniques de remplacement de données de mémoire cache consistent à associer une valeur de priorité à chacune des données élémentaires stockées, la valeur de priorité associée à chaque donnée élémentaire étant une estimation de la durée du temps d'arrêt UCT si une tentative est faite pour récupérer la donnée élémentaire dans la mémoire cache lorsque la donnée élémentaire n'y est pas stockée. Quand une entrée dans la mémoire cache doit être remplacée les valeurs de priorité sont analysées pour déterminer une valeur de priorité de plus faible niveau. Une des données élémentaires qui présente la valeur de priorité de plus faible niveau est sélectionnée et remplacée par une donnée élémentaire de remplacement. La valeur de priorité d'une donnée élémentaire peut être déterminée en fonction du nombre d'autres instructions qui ont été cherchées et stockées dans une mémoire tampon entre un intervalle de temps défini par le début et la fin de la récupération de la donnée élémentaire dans la mémoire principale, l'exécution des autres instructions dépendant de l'achèvement de la récupération de la donnée élémentaire. Dans d'autres aspects de l'invention les valeurs de priorité des entrées de mémoire cache peuvent être périodiquement réduites pour améliorer le taux de réussite de mémoire cache et peuvent également être réinitialisées à chaque fois que la donnée élémentaire associée est trouvée pour assurer le maintien des données élémentaires de valeur dans la mémoire cache.
