Title: Bit allocation method in a multicarrier system
Inventor: YONG MEI
IPC: H04L1/00
Filed: 2000-12-15
Abstract: A system and method that generates rate options for ADSL transceivers is described. The system and method dedicates discrete multitone symbol bandwidth to bearer channels based on a prioritization of the bearer channels. A rate option generator determines the number of bytes contained in discrete multitone symbols modulated by a modulator. The rate option generator also receives a prioritization of the bearer channels and allocates portions of the number of bytes contained in the discrete multitone symbol to the bearer channels based on the prioritization. In order of priority, each bearer channel is allocated its maximum allowed number of bytes so long as discrete multitone symbol bandwidth remains available. Also, as part of the discrete multitone symbol bandwidth allocation, a bearer channel is not allocated less than its allowed minimum number of bytes.

Title: Modulation of il-2- and il-15-mediated t cell responses
Inventor: STROM TERRY B
IPC: C12N5/09
Filed: 2001-09-14
Abstract: The present invention is based, in part, on expression studies of IL-2 and IL-15 receptor subunits by cycling T cells in vivo. In one embodiment, the invention generally features novel combinations of IL-2 and IL-15 antagonists and methods of suppressing the immune response by administering these antagonists. In each case, suppression is achieved by administration of a first agent that targets an IL-15 molecule or an IL-15 receptor (IL-15R) and a second agent that targets an IL-2 molecule or an IL-2 receptor (IL-2R). More generally, the invention features novel combinations of agents that, when administered to a patient (or to a transplant ex vivo, reduce the number of antigen-reactive T cells. For example, the invention features compositions (e.g., pharamaceutically acceptable compositions) that include two or more agents, each of which promote T cell death. Alternatively, the composition can contain at least one agent that promotes T cell death and at least one agent that inhibits T cell proliferation. The agent that promotes T cell death can promote AICD (activation induced cell death), passive cell death, ADCC  (antibody dependent cell-mediated cytotoxicity) or CDC (complement directed cytotoxicity).

Title: Adaptive filtering with reference accelerometer for cancellation of tool-mode signal in mwd applications
Inventor: DUBINSKY VLADIMIR
IPC: G01V1/36
Filed: 2001-11-14
Abstract: A method for eliminating the tool mode signal from a received combined signal (120) including both tool mode and formation mode components, uses a signal from a reference receiver (112) that is consists primarily of the tool mode signal (122). A transfer function is derived relating the time reversed combined signal and the time reversed reference signal and used to predict the tool mode portion of the combined signal. Subtracting the predicted tool mode portion of the combined signal from the combined signal gives an estimate of the formation mode component.

Title: System and method for reducing bottlenecks in low data rate networks processing facsimile data transmission
Inventor: KARMI GADI
IPC: H04N1/411
Filed: 1994-11-15
Abstract: System and method for minimizing data bottlenecks in Low Data Rate Networks (LDRNs) that communicate facsimile transmissions. An LDRN is a facsimile network having a transmission data rate less than the data rate of the FAX machines serviced by the network. The system and method can be implemented in any type of LDRN, including analog and digital wired LDRNs, as well as analog and digital wireless (e. g., cellular) LDRNs. The system and method involve processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible, thereby minimizing any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate.
