Patent CA-2286439-A1 (CA)
Inventor: SACUTA WALTER
IPC: G01S13/02
Filed: 1999-10-15
Abstract: A time domain reflectometry method for determining positions of upper and lower interfaces of a first liquid floating on a second liquid within a vessel, using a system includes a probe in the form of a transmission line extending vertically within the vessel from a point above a highest level to be measured of the upper interface to below a lowest level to be measured of the lower interface, and an impulse radar system connected to the upper end of the transmission line, the micro impulse radar system including a microwave pulse generator. The method includes the steps of constructing and installing the transmission line so as to have a pulse response substantially free of internal reflections except at its ends, matching the radar system to the upper end of the probe sufficiently well to avoid the generation of noise or spurious echoes having an amplitude which is comparable to the magnitude of first and second return pulses due to reflections occurring at the upper and lower interfaces, while generating a readily detectable reflection forming a fiducial return pulse marking the end of the probe, and determining the positions of the upper and lower interfaces of the liquid being calculated by determining the time of flight between the fiducial return pulse and the first return pulse and calculating therefrom distance along the probe to the first interface, and determining the time of flight between the first and second return pulses and applying thereto a scaling factor dependent of the dielectric constant of the first liquid so as to determine a distance between the first and second interface. The method is preferably implemented using an MIR system, and sampling of reflected energy is preferably under control of a time base generator whose output delay is linearized by negative feedback.

Title: System and method for capacity shaping in an internet environment
Inventor: LUMELSKY LEON L
IPC: G06Q10/10
Filed: 2000-05-10
Abstract: A system providing access to web objects that matches predicted demand for web objects to available capacity on web servers. The system implements methods to dynamically shape both demand and capacity based on certain criteria. The system provides methods to dynamically shape demand for an object based on criteria such as arrival time, incoming geography, and costs requirements. In particular, the present invention characterizes future demand for an object based on aggregation and forecasting of past demand for such object. The system effectively permits control and customization of capacity across one or more media servers based on characteristics associated with the demand across one or more of them, and particularly, based on the dominating geographical traits of past demand. Moreover, the system dynamically shapes capacity by: (a) controlling the number of replicas associated with an object; and, (b) controlling the placement of these replicas across servers in a distributed network. In particular, the system drives capacity shaping measures over a particular object based on its predicted demand. Consequently, the number and location of replicas associated with an object is made to be variable over time and driven by predicted demand for a web object.

Title: Immunosuppression by blocking t cell co-stimulation signal 2 (b7/cd28 interaction)
Inventor: DORLING ANTHONY
IPC: A61K35/14
Filed: 1999-04-30
Abstract: The invention provides means and methods for inhibiting T-cell mediated rejection of a xenotransplanted organ by blocking the delivery of co-stimulatory signal 2 (the B7/CD28 interaction) in order to prevent the activation of xenoreactive T-cells in the recipient. In a first aspect, co-stimulation is prevented by administration to the organ recipient of a soluble form of CTLA-4 from the xenogeneic donor organism. This preferentially binds B7 on the xenograft and blocks the interaction between B7 on the xenogeneic donor cells and CD28 on recipient T-cells. In a second aspect, co-stimulation is antagonised by expressing a ligand for CTLA-4 on the xenogeneic donor cells. This ligand binds to CTLA-4 on activated T-cells of the recipient and antagonises signal 2. In a third aspect, co-stimulation is prevented by expressing recipient organism MHC class II on the surface of the cells of the xenogeneic donor organ. The donor cells are thus able to present xenoantigens to a recipient T-cell in the context of self-MHC class II. If the donor cells do not express B7, or if B7 is blocked, the xenoreactive recipient T-cell becomes anergic.
