Patent CA-2293239-C (CA)
Inventor: KECHRIOTIS GEORGE
IPC: H04J1/00
Filed: 1998-06-09
Granted: 2007-07-17
Abstract: Selon cette invention, des données sont réparties entre les voies d'un système de communication en boucle de données asynchrones (ADSL) d'abonnés, conformément à un algorithme adaptatif qui, de temps en temps, mesure le rapport signal/bruit des différentes voies et trouve pour chaque voie une marge dépendant, si possible, de l'obtention d'un taux donné d'erreurs sur bits et d'un taux de transmission de données voulu. La répartition des marges se fait par augmentation du rapport signal/bruit de la constellation, de sorte que l'efficacité du calcul soit améliorée et que la redétermination des tables d'affectation de bits soit possible lors de la transmission, selon les besoins. Des paires de tables d'affectation de bits sont conservées dans l'émetteur et le récepteur, et une table de chaque paire de l'émetteur et du récepteur est remise à jour alors que l'autre paire est utilisée pour la commande de la communication.

Title: Battery accumulating apparatus
Inventor: GOHNAI TOSHIO
IPC: H02J7/02
Filed: 2000-05-31
Granted: 2004-02-17
Abstract: In a battery accumulating apparatus, a charge current I1 from the charging solar battery 9 is supplied to the storage battery 5 through the switch 10, and charges the storage battery 5. The charge controller 4b detects each cell voltage of the storage battery 5, and when any of cell voltage reaches a prescribed value, the charge controller 4b turns the switch 10 in the ON status to the OFF status. The charge controller 4b has a function which generates the charge currents I2 and I3 (I2 > I3) whose levels are lower than the charge current I1, according to the output from the charging solar buttery 9, and supplies the charge current I2 to the storage battery 5 at the same time as the turning OFF of the switch 10, and charges the battery. The storage battery 5 is charged by the charge current I2, and when any of cell voltage reaches a prescribed value, the charge controller 4b switches the charge current I2 to the charge current I3, and supplies the charge current I3 to the storage battery 5.

Abstract: A tampon for feminine hygiene or medical purposes comprising a nonwoven cover having at least one, outwardly directed, smooth surface and substantially enclosing a liquid absorbing core wherein the nonwoven cover comprises at least partly thermoplastic, heat-sealable fibers and pressed to the final shape of the tampon. Before the tampon blank is covered with the nonwoven covering web, said web was subject to the use of heat and pressure during the manufacturing of the tampon as to smooth out at least the outer surface of the nonwoven covering web, whilst maintaining the structure of the nonwoven covering web and the absorbency of the tampon. Thereby, it is achieved that the tampon can also be more easily and more comfortably introduced into and withdrawn from a body cavity before and after the days of stronger menstruation or at the occurrence of only less vaginal exudation as garment protection.

Granted: 2013-06-25
Abstract: One of the impediments to the treatment of some human brain tumors (e.g., gliomas) has been the degree to which they expand, migrate widely, and infiltrate normal tissue. We demonstrate that a clone of multipotent neural progenitor stem cells, when implanted into an experimental glioma, will migrate along with and distribute themselves throughout the tumor in juxtaposition to widely expanding and aggressively advancing tumor cells, while continuing to express a foreign reporter gene. Furthermore, drawn somewhat by the degenerative environment created just beyond the infiltrating tumor edge, the neural progenitor cells migrate slightly beyond and surround the invading tumor border. When implanted at a distant site from the tumor bed (e.g., into normal tissue, into the contralateral hemisphere, into the lateral ventricles) the donor neural progenitor/stem cells will migrate through normal tissue and specifically target the tumor cells. These results suggest the adjunctive use of neural progenitor/stem cells as a novel, effective delivery vehicle for helping to target therapeutic genes and vectors to invasive brain tumors that have been refractory to treatment.

Title: Cleaning using welding lances and blasting media
Inventor: CHERICO STEVE
IPC: F27D25/00
Filed: 2000-02-11
Granted: 2008-12-30
Abstract: It is possible to clean high temperature (over 400, e.g. over 1000, degrees F) surfaces in a time and cost efficient manner by using a liquid-cooled ceramic welding lance (11) to direct (at super-atmospheric pressure) a blasting media at the surfaces to be cleaned. The blasting media (23) is preferably combustible at the temperature of the environment surrounding the surfaces, and may include one or more organic agricultural abrasive materials (preferably black walnut shells) as the sole or primary constituent. Blasting may be practiced by directing the media at the surfaces to be cleaned (15) at a pressure of between about 40-100 psi, for example continuously for as long as is necessary (e.g. more than 30 minutes), without any need to remove the lance (11) from the environment. The method is desirably practiced to clean, while in operation or in situ, metal surfaces having sca le buildup which adversely affects the ability of the metal surfaces to transfer heat, reheat tubes, process tubes, furnace surfaces, or the like .

Abstract: An anti-microbial and/or anti-fungal synthetic fiber and various products made partially or wholly therefrom. The fiber comprises various thermoplastic polymers and additives in a mono-component form or a bi-component form in either a core-sheath or side-by-side configurations. The anti-microbial synthetic fibers comprise inorganic anti--microbial additives, distributed in certain areas to reduce the amount of the anti-microbial agents being used, and therefore the cost of such fibers. The fibers can incorporate anti-microbial additives so that they are not removed by repeated washing in boiling water and in dry clean cycles and become ineffective and conversely enhance access to the additives by washing or the like. The fibers comprise high tenacity polymers (e.g. PET) in one portion and hydrolysis resistance polymers (e.g. PCT) in another portion with the additives. The fibers can further be blended with non-anti-microbial fibers such as cotton, wool, polyester, acrylic, nylon etc. to provide anti-microbial finished fabrics.

Title: Improvements in receivers for television signals
Inventor: BODKIN NIGEL
IPC: H04N5/781
Filed: 2000-08-09
Granted: 2010-12-07
Abstract: A Hard Disk Recorder (HDR)(3) is arranged to receive signals signals defining television programmes and television programme schedule data. The HDR    receives updated programme schedule data substantially constantly in a dedicated programme schedule data channel. The HDR is arranged to output the programme schedule data for display on a television screen (2). The HDR comprises a hard disk (16) for recording received television programmes. A remote control (28) is provided to select television programmes to be recorded from the displayed programme schedule. Furthermore, the HDR is arranged to receive additional programme schedule information included in each of the received television channels which information is used to control the hard disk to record pre-programmed television programmes according to schedule. The hard disk is operable to record simultaneously two different television programmes received in different channels.  Also, the HDR is operable to replay a currently broadcast programme offset in time.  The time offset can be overcome by playing back the part of the programme inside the time offset at an increased frame rate. Furthermore, the HDR is arranged to receive transition signals indicating transitions between parts of programmes, such as transitions between advertisements and the "actual" programmes. The HDR is operable to use these transition signals, for example, to skip between transitions in previously recorded programmes replayed from the hard disk.
