Patent CA-2414951-A1 (CA)
Inventor: PAPERNYI SERGUEI
IPC: H04B10/29
Filed: 2001-07-06
Abstract: A pumping scheme for distributed Raman amplification (DRA) in optical fiber telecommunication systems is disclosed in which pump energy at the wavelength(s) required for DRA of the transmitted optical signal(s) is developed within the transmission fiber through a series, n, where n>=1, of Raman conversions. In preferred embodiments, a "primary' pump source of wavelength shorter than the ultimately desired pump wavelength(s) is launched into the fiber along with one or more significantly lower-power secondary "seed' sources. The wavelength and power of the secondary source(s) are chosen such that, when combined with the high-power primary source, Raman conversions within the fiber ultimately lead to the development of high power at the desired pump wavelength(s). In another embodiment, one or more seed sources are replaced by reflecting means to return, into the fiber, backward-travelling amplified spontaneous Raman scattered light resulting from high power in the fiber at a wavelength one Raman shift below the desired seed wavelength. In either case, the high power at the wavelength(s) required for DRA of the signal(s) is developed over a distributed length of the fiber rather than being launched from a terminal point, as in the prior art. Consequently, the maximum power at the desired pump wavelength(s), and the peak signal gain, occur some distance into the fiber from the launch terminal. In one exemplary embodiment, a distributed Raman preamplifier, improved noise performance results, since the Raman gain occurs, on average, at a greater distance from the receiving terminal than with the standard pumping scheme.

Abstract: A fastener for attaching two panels (5) and (6) having aligned apertures consists of a fastener which utilizes a retainer (1), a through-shaft (2), a  rubber sleeve (3), and an end cap (4). The shaft extends through the retaine r and a rubber sleeve is fitted around the shaft being retained axially by cap  (4) which is attached to the end of the shaft (2). The pre-assembled fastene r is attached to a first panel (5) preferably by clinch-type attachement. Cam surfaces on the underside of a head of the shaft and inside the retainer (1)  cooperate such that when the head of the shaft is turned, the shaft (2) is withdrawn from the retainer compressing the rubber sleeve (3) between the en d cap and a base of the retainer (1). This causes the rubber sleeve to bulge a nd apply a clamp load against the backside of the second panel (6). Thus the tw o panels are captured between the expanded area of the rubber sleeve and the base of the retainer. A series of radial grooves in the retainer cam ramp ac t in concert with a protrusion on the underside of the shaft to provide multip le resting points in the rotation. The fastener provides a single, fully- assembled component which works through standard round holes in the panels t o provide panel attachment in a variety of panel thicknesses that is also vibration resistant.

Title: Low cost vsb encoder and rf modulator for supplying a substantially 6 mhz vsb signal to digital television receiver
Inventor: HORWITZ THOMAS P
IPC: H04N21/438
Filed: 2001-07-23
Abstract: A system supplies a compressed digital signal to a digital television receiver and includes a source of compressed baseband signal. An encoder encodes the baseband signal in a digital format, and the baseband signal has a frequency.  The frequency of the encoded baseband signal is shifted by a first frequency shifter. A first interpolator interpolates an output of the first frequency shifter, a second interpolator that interpolates an output of the first interpolator, and a third interpolator that interpolates an output of the second interpolator. A second frequency shifter shifts a frequency of an output of the third interpolator to produce a signal at a selected channel.

Title: Substrat pouvant etre active par une tension
Inventor: GANNON MICHELLE RENEE
IPC: A61F13/49
Filed: 2001-10-31
Abstract: La présente invention concerne un papier ménager aux propriétés intensives doubles. Le papier ménager de l'invention possède un premier ensemble de propriétés intensives telles que la densité, la surface active, l'épaisseur et le volume vide, telles qu'elles se présentent au consommateur. Le consommateur active de manière plastique le papier ménager de l'invention en le tirant pour le mettre en tension. Une série de fentes (44) ou d'autres lignes de faiblesse s'allongent dans une direction parallèle à la ligne de tension, permettant au papier ménager d'atteindre un second état de propriétés intensives. La valeur du second état de propriétés intensives est différente après l'activation. Le changement de valeur des propriétés intensives permet d'économiser sur les coûts d'expédition, étant donné qu'on expédie au consommateur un produit à densité plus élevée. Au point d'utilisation, le consommateur active le produit afin d'obtenir une surface active augmentée et une moindre densité. L'augmentation de la surface active et la réduction de densité concomitante permettent d'obtenir une efficacité de nettoyage augmentée. L'état susceptible d'activation plastique peut être obtenu à l'aide d'une série de fentes (44) ou d'autres lignes de faiblesse dans le papier ménager. Le papier ménager de l'invention peut comprendre des fibres cellulosiques et/ou synthétiques et il peut être utilisé comme mouchoir en papier, serviette de toilette, essuie-mains, serviette en papier, lingette pour le corps, tête de balai à laver, etc.

Abstract: A method for the binary zoning of a Storage Area Network (SAN) for security is disclosed, for a SAN with physical devices consisting of a first array of hosts (1) and a second array of storage devices (4), and a SAN Switch (2, 2A) coupled intermediate the hosts and the storage devices. The SAN Switch routes I/O commands and accepts zoning commands. The method is based on starting operation of the SAN with mutually isolated physical devices and accepting zoning commands only after running security verification procedures requiring that hosts be authenticated and that storage devices be identified. Zoning is dynamically controlled from a workstation (8) operated by a System Administrator entering meta-zoning instructions, which are used to automatically program the zoning of the SAN Switch for legitimate physical devices. The method is implemented for security and booting of a SAN.
