Title: Method for determining therapeutic index from gene expression profiles
Inventor: MARTON MATTHEW
IPC: C12Q1/6883
Filed: 1999-12-27
Abstract: This invention provides methods for determining drug specificity, therapeutic index and effective doses for individual patients. According to the methods of the invention, graded levels of drug are applied to a biological sample or a patient. A plurality of cellular constituents are measured to determine the activity of the drug on a target pathway and at least one off-target pathway.  A drug specificity is determined by comparing the target and of target activities of the drug. A therapeutic concentration (or dose) is defined as a concentration (or dose) of the drug that induces certain respone in the target pathway. A toxic concentration (or dose) is defined as a concentration (or dose) of the drug that induces certain response in the off target pathway.  Therapeutic index is the ratio of the toxic concentration over therapeutic concentration. Methods are also provided to determine an effective dose of a drug for a patient by measuring the activity of the drug on the particular patient.

Title: Signal blocking for a base radio control station
Inventor: KOWALSKI JOHN
IPC: H04B17/00
Filed: 1996-06-27
Abstract: A method and apparatus for communication data signal blocking for a base radio control station (RCS) which wirelessly communicates with subscriber units (SUs) via a spread spectrum communication system is disclosed. A transmitter sends signals as a baseband combined signal over global and assigned channels to SUs. The SUs are set to initial power levels and the power levels are adjusted in advance of receiving signals on assigned channels. The power levels are combined to define an RCS transmitter power level, which is preferably a root mean square value of the baseband combined signal. The transmission power levels are adjusted in response to corresponding power control signals received from the SUs. Transmission of a new communication data signal on an assigned channel is blocked if a predetermined RCS transmitter power level limit is reached before commencing transmission of that signal.

Title: Communications system having enhanced fault tolerance
Inventor: JAPPINEN TEEMU
IPC: H04L12/56
Filed: 2001-01-12
Abstract: The invention relates to communications systems, and particularly to enhanci ng tolerance to failures in network elements and transmission systems. The faul t tolerance is achieved by 1) providing two or more active ATM permanent virtu al channel (PVC) connections (31a-31d) between a core network element (3G-SGSN)  and an access network element (RNC), and 2) providing a separate ATM interfa ce unit (IU1-IU4) for each such ATM PVC connection in the core network element (3G-SGSN). The user and signalling traffic is distributed among these active  connections and interface units. In case of a failure in one of the ATM PVC connections or interface units (IU1-IU4), the communication is maintained ov er the other connection(s) and interface unit(s). Thus, only part of the transport capacity is lost, and a total block of communication is avoided. A ny new communication will be setup over the other connections.
