Title: Methods and compositions for inhibiting hexokinase
Inventor: NEWGARD CHRISTOPHER B
IPC: C12N15/11
Filed: 1997-01-17
Abstract: Disclosed are compositions and methods for inhibiting hexokinase enzymes in mammalian cells. Specifically provided are proteins that stimulate the production of trehalose-6-phosphate and their respective genes; hexokinasespecific ribozymes and genes encoding such constructs; and agents that competitively reduce hexokinase activity, e.g., by displacing hexokinase from mitochondria, and their respective genes. The latter group of agents includes inactive hexokinases and fragments thereof that retain mitochondrial binding functions and hexokinase-glucokinase chimeras that further substitute glucokinase activity for hexokinase activity. Mammalian cells including such hexokinase inhibitors, methods of making such cells and various in vitro and in vivo methods of using cells with reduced hexokinase activity are also described herein.

Title: System and method for providing caller identification in conjunction with calling card calls
Inventor: MALIK DALE W
IPC: H04M3/42
Filed: 1998-10-26
Abstract: A system and method for providing calling party identification information to a called party in an intelligent network. A long distance calling card company maintains a subscriber database that includes preferred calling number data and calling name data for each subscriber. When a subscriber places a calling card call, the service provider looks up the subscriber's database record, retrieves the preferred calling number data, and sends the calling number data to the terminating end office. A calling name query from the terminating end office is routed to a database that includes data from the service provider's subscriber database. The caller's name is retrieved and returned to the terminating end office and displayed on the called party's display device, along with the calling number data, date, and time. By directing the calling name inquiry to the service provider's subscriber database, or to a database that includes relevant data from the subscriber database, the called party's caller ID display device is able to display both the calling party's identity and a valid call back number.

IPC: H04L12/26
Filed: 1998-02-13
Abstract: A system, method and storage medium embodying computer-readable code for analyz-ing traffic data in a distributed computing envi-ronment are described. The distributed comput-ing environment includes a plurality of intercon-nected systems operatively coupled to a server, a source of traffic data hits and one or more results tables categorized by an associated data type. Each results table includes a plurality of records. The server is configured to exchange data packets with each interconnected system.      Each traffic data hit corresponds to a data packet exchanged between the server and one such in-terconnected system. Each traffic data hit is col-lected from the traffic data hits source as access information into one such record in at least one results table according to the data type associ-ated with the one such results table. Each of the records in the results table corresponds to a different type of access information for the data type associated with the results table. The ac-cess information collected into the results tables during a time slice is summarized periodically into analysis results. The time slice corresponds to a discrete reporting period. The access in-formation is analyzed from the results tables in the analysis results to form analysis summaries according to the data types associated with the results tables.

Abstract: Compositions and processing conditions are disclosed for the production by rotomolding of polypropylene foams, hither to satisfactorily produced only by injection molding and extrusion molding. Rheological properties of the polypropylene resin, processing conditions and choice of composition of the chemical blowing agent were found to play important roles in obtaining high quality polypropylene foam structures. High strength fine-cell polypropylene foams could in particular be formed by first melt compounding a suitable chemical blowing agent with the resin under conditions which allow for homogeneous mixing without appreciable decomposition of the blowing agent.
Patent CA-2306089-A1 (CA)
Title: High-speed, adaptive iddq measurement
Inventor: FERGUSON KENNETH WILLIAM
IPC: G01R31/26
Filed: 2000-04-14
Abstract: The invention facilitates measurement of IDDQ values which characterize a test device. A current mirror "mirrors" the current flowing from a power supply through the test device, such that the same current flows through a second current path coupling the power supply to an integrator formed by a transistor connected across a capacitor. Application of a first logic signal to the transistor turns the transistor on, causing current flowing in the second current path to bypass the capacitor, thereby discharging the capacitor. Application of a second logic signal to the transistor turns the transistor off, causing current flowing in the second current path to flow through and charge the capacitor. The rise time of the voltage produced across the charg-ing capacitor is proportional to the IDDQ current value which charac-terizes the test device. The invention further facilitates signature analysis of a test device for defects. A plurality of IDDQ reference values are derived, each value representing quiescent state operation of a defect-free copy of the test device. A corresponding IDDQ test value is derived for each IDDQ reference value. Each test value represents quiescent state operation of the test device after application thereto of the test vector which produced the corresponding reference value. The reference values are compared to their corresponding test values and a plurality of scaling factors are derived. Each scaling factor represents a proportionality between one of the reference values and the corresponding test value. The test device is declared to be non-defective if the scaling factors are equal to one another within an error range which is predefined with respect to the respective test values. Otherwise, the test device is declared to be defective.
