Patent CA-2440230-C (CA)
Inventor: OBERG MAGNUS
IPC: H04B10/275
Filed: 2002-03-11
Granted: 2011-09-27
Abstract: An optical WDM network for use for instance in a larger e.g. meshed network is the hubbed type and comprises parallel fiber ring paths (1b), a hub (3h) and satellite nodes (3A, 3B, 3C) connected in the ring path. Client equipments are connected to the hub and the satellite nodes. A client equipment connected to the main node can communicate with a client equipment connected to any of the satellite nodes, using a number of wavelength channels equal to the number of client equipments in the satellite nodes. The wavelength channel used for transmission from the hub can e.g. be fixed or selected by a tunable optical transmitter (31). The WDM transmitters (9) in the satellite nodes transmits light signals in a fixed one of the wavelength channels to the fiber ring path. A single band drop filter (35) is arranged in the main node to receive the light signals from the satellite nodes. The band drop filter has a drop range selected to drop selected ones of the wavelength channels used by the WDM transmitters in the satellite nodes. This allows the use of light signals of wavelength channels outside the drop range of the band drop filter for carrying information in the network. In the network flexible connections are achieved in without using cross-connect elements.

IPC: B04C5/22
Filed: 2003-10-31
Granted: 2007-04-03
Abstract: A filter assembly for a cyclone type dust collecting apparatus of a vacuum cleaner. In the cyclone type dust collecting apparatus of the vacuum cleaner which centrifugally separates contaminants from an externally-drawn air and collects the separated contaminants therein, the filter assembly filters contaminants floating in an air which is discharged through an exhaust port of the vacuum cleaner. The filter assembly is provided with a rotary filter rotatably connected with respect to the exhaust port and a filter rotating unit. The rotary filter is provided with a suction grill portion at the outer circumference and a discharge port fluidly connected to the exhaust port of the cyclone type dust collecting apparatus, and the filter rotating unit is for rotating the rotary filter and thus removing contaminants filtered on the surface of the suction grill portion. The contaminants accumulated on the outer surface of the filter are easily removed as the filter is rotated in association with the engagement and disengagement of the dust receptacle from a body of the cyclone type dust collecting apparatus. The filter assembly has a simple structure, and thus is manufactured at a reduced cost and also is easy to assemble and disassemble.

Title: Restricted expression lentiviral vectors
Inventor: TRONO DIDIER
IPC: C12N15/63
Filed: 2002-09-30
Granted: 2019-08-20
Abstract: The present invention provides HIV-derived lentivectors which are safe, highly efficient, and very potent for expressing transgenes for human gene therapy, especially, in human hematopoietic progenitor cells as well as in all other blood cell derivatives. The lentiviral vectors comprise promoters active to promote expression specific to cell types or tissues. Further, promoters are providing that are amenable to control by activators, enhancers, or repressors. These vectors are in a self-inactivating configuration for biosaftey. Additional promoters are also described. The vectors can also comprise additional transcription enhancing elements such as the wood chuck hepatitis virus post-transcriptional regulatory element, without any decrease in the specificity or control exerted by the promoters. These vectors therefore provide useful tools for genetic treatments such as inherited and acquired lympho-hematological disorders, gene-therapies for cancers especially the hematological cancers, as well as for the study of hematopoiesis via lentivector-mediated modification of human HSCs.
