Filed: 2001-06-07
Abstract: An approach for measuring scheduler efficiency is disclosed. A scheduler (603) has metrics measurement capability, in which scheduler counters (803, 805, 807, and 809) correspond to scheduling events. A counter logic (801) selectively increments the scheduler counters (803, 805, 807, and 809). The counter logic (801) is coupled to queues (607) that store cells. The performance metrics are computed based upon values of the counters (803, 805, 807, and 809). The scheduler (603), according to one embodiment of the present invention, is deployed in a satellite communication system.

Title: Raman-amplified optical transmission system
Inventor: JUDY ARTHUR F
IPC: H04B10/294
Filed: 2001-06-18
Abstract: A Raman-amplified optical transmission system [80] includes a source of optical transmission signals having a system wavelength, .lambda.s, that are connected to one end of the of a first optical fiber [50-1] having a large effective area, i.e., A eff >= 70 µm2. The other end of the first optical fiber is connected to a second optical fiber [50-2] having a small effective area, i.e., A eff <= 60 µm2.  Preferably, the first and second optical fibers have opposite dispersion signs. A wavelength-division multiplexer [87], for example, couples optical transmission signals .lambda.1....lambda.n, from an optical pump [88] to the second optical fiber that cause it to exhibit stimulated Raman scattering, which provides amplification of the optical transmission signals. Preferably, the optical pump signals propagate along the second optical fiber in a direction that is opposite the direction of the optical transmission signals.   Exemplary cables [500, 600] are disclosed that include both large and small-effective-area fibers. One cable [600] is defined by a planar array of optical fibers that are bound together by a matrix material [65] in what is referred to as a ribbon, and another cable [500] is defined by fibers that are enclosed within one or more plastic tubes [52].

Abstract: Un aspect de la présente invention concerne un circuit de conversion de fréquence doté d'une paire d'oscillateurs locaux. Les oscillateurs locaux sont des synthétiseurs de fréquence qui reposent sur une référence de fréquence externe. Le circuit de conversion de fréquence est configuré pour convertir une fréquence en signal d'entrée égal à une différence des fréquences des signaux issus de la paire d'oscillateurs locaux; générer un signal de différence de fréquence d'oscillateur; générer un signal d'erreur par le biais du signal de différence de fréquence d'oscillateur et d'un signal de référence interne dérivé de la référence de fréquence externe; et ajuster une phase de l'un des deux oscillateurs par le biais du signal d'erreur. L'incorporation du circuit de conversion de fréquence décrit ci-dessus permet d'éliminer essentiellement des bruits de phase de diviseur, notamment ceux générés par des diviseurs préalables traditionnels. De plus, l'utilisation de deux oscillateurs locaux permet d'obtenir; un circuit de conversion de fréquence capable de convertir une vaste gamme de fréquences et de fournir une résolution élevée. Ce circuit de conversion de fréquence est aussi bien adapté aux récepteurs qu'aux transmetteurs, et convient particulièrement aux systèmes de télévision numérique.

Title: Apparatus and method for determining an approximation of the stroke volume and the cardiac output of the heart
Inventor: BERNSTEIN DONALD P
IPC: A61B5/053
Filed: 2001-07-04
Abstract: The invention relates to an apparatus and a method for deter-mining an approximate value for the stroke volume and the cardiac output of a person's heart. The apparatus and method employ a measured electrical impedance, or admittance, of a part of a person's body, namely, the thorax. This part of a person's body is chosen because its electrical impedance, or admittance, changes with time as a consequence of the peri-odic beating of the heart. Accordingly, the measured electri-cal admittance or impedance can provide information about the performance of the heart as a pump.

Title: Bottomless compartmentalized in-ground garden container
Inventor: GOLDBERG LAURI
IPC: A01G9/02
Filed: 2001-07-05
Abstract: A bottomless compartmentalized in-ground garden container includes a rigid outer wall defining a perimeter and having opposite upper and lower edges around the perimeter. Rigid compartment walls extend at least partially across the perimeter. The compartment walls intersect the outer wall and other compartment walls so as to form compartments within the perimeter. The upper edge of the outer wall has a widened portion so as to have a thickness greater than a thickness of the lower edges of the outer wall and the compartment walls. The lower edges of the outer wall and the compartment walls are adapted to slice into soil. The widened portion is adapted for distributing pressure applied manually downwardly by a downward hand pressure onto the widened portion so as to drive the lower edges of the walls into the soil. The container is bottomless so as to leave the outer walls and the compartment walls exposed to soil forced upwardly into the compartments.
Patent CA-2354083-A1 (CA)
Inventor: FISHER PAUL DAVID
IPC: A01N25/30
Filed: 1999-11-19
Abstract: This invention relates to a stable aqueous silane emulsion with constant particle size. The emulsion comprises a continuous water phase, a discontinuous silane phase, and an emulsifier system. The emulsifier system contains a primary surfactant and a cosurfactant. The primary surfactant functions to prevent coalescence of particles, by steric or ionic repulsion between particles. The cosurfactant prevents diffusion of the silane into th e aqueous phase. The combination of primary surfactant and cosurfactant result s in an adsorbed inner layer of cosurfactant between the silane and the outer layer of a mixture of both surfactants which contacts the water phase. The combination of primary surfactant and cosurfactant provides a barrier which prevents diffusion of silane into the water phase. A method for preparing th e emulsion is also disclosed.

Abstract: Deep penetration gas tungsten arc welds are achieved using weld penetration containing one or more compounds selected from the group of compounds consisting of a) a titanium oxide, b) nickel oxide, c) a metal silicide, and d) mixtures of these compounds. A flux containing at least two titanium oxides, nickel oxide, and a manganese silicide is particularly useful for welding a wide variety of materials including nickel-based alloys and carbon and stainless steels. As shown in the graph, a flux containing 23.1 wt. % TiO, 23.1 wt. %      TiO2, 23.1 wt. % Ti2O3, 23.1 wt. % NiO and 7.5 Mn15Si26 achieves at least a 200 percent increase in penetration (filed circles) over a weld without flux (open circles) when used with Alloy 718. The flux can be applied as a paste, as part of a cored wire or rod, coated on the exterior of a filler wire or rod.  Alternatively it can be mixed with a polymer binder and applied to the weld zone as a hot melt, paint, tape, adhesive, rod, wire or a stick.

Title: Antigen-specific induction of peripheral immune tolerance
Inventor: AUGUST J THOMAS
IPC: A61P37/06
Filed: 2000-04-10
Abstract: Fas ligand (CD95L) induces apoptosis in activated T cells through the process of Activation Induced Cell Death (AICD). Gelatin nanoparticles are virus sized gelatin-protein-DNA complexes which can encapsulate multiple DNA vectors and proteins, and which are thought to act by increasing in vivo transfection of antigen presenting cells. By injecting mice with gelatin nanoparticles containing a murine Fas ligand (CD95L) DNA vector and a .beta.-galactosidase (LacZ) model antigen vector, the T cell response specific for .beta.-gal was ablated without effecting the response to a secondary antigen. In effect, this "tolerization" injection induceS antigen specific peripheral tolerance in study mice, and is applicable to the treatment of autoimmune diseases when self-antigens such as Myelin Basic Protein are co-delivered with the Fas ligand.
