Appl. No.:

09/823657

International Classification:

C12Q 100

US Classification:

435 4, 435 26, 435 23, 435 24, 435963

Abstract:

A method of improving a phenotypic defect in a cell that contains a conformationally defective target protein wherein the conformational defect causes the phenotype defect, comprising contacting a first cell that expresses said conformationally defective target protein with an amount of a protein stabilizing agent that is effective to improve the conformational defect, thereby improving the phenotypic defect of the first cell in comparison with a second cell having the same conformationally defective target protein and phenotypic defect, wherein the second cell is not contacted with the protein stabilizing agent.

International Classification:

G06F 1516

US Classification:

709233

Abstract:

A system for classifying, monitoring, controlling and otherwise managing and allocating bandwidth of a network to data streams. A method for allocating bandwidth of a data network to a plurality of data streams is provided. The method comprises specifying apportionment of the bandwidth to a plurality of data classes. Receiving a plurality of data streams wherein each data stream has an associated data class. Negotiating a transfer rate for each data stream, wherein the transfer rate is limited to the bandwidth apportioned to the data class associated with each data stream and transmitting the data streams on the data network at the negotiated transfer rates.

International Classification:

G06F 1730

US Classification:

707 4, 707 5

Abstract:

In a network, a query originator injects queries of network devices into the network at a query node using query messages. The network transports the query messages to the network devices, or to network nodes at which queries about the network devices can be answered. Query responses from the network devices or network nodes are directed through the network to a collection node or nodes. As an internal network node receives multiple query responses from network devices, the internal network node might aggregate, as needed, the multiple query responses into an aggregated query response that preferably occupies less bandwidth than the aggregated multiple query responses. Where the result desired at the collection node is a computed function of the multiple query responses, the computed function can be performed at each internal network node on the multiple query responses received at that node, thus distributing the computation needed to form a collected response to the query. Queries might request real-time or non-real-time responses and queries might request one response, periodic responses or one response for each occurrence of an event. The internal network nodes might store lookup tables, or access a centralized lookup table, that specify details of queries, thus obviating the need for each query message to carry all of the necessary details of the query.

International Classification:

G06F019/00

US Classification:

701111, 701114, 324379, 73116

Abstract:

Methods and devices for measuring and calculating various kinds of parameters of a running engine are disclosed. A camera may be positioned to capture a plurality of images of a moving component that is being driven by the an engine. From the plurality of images, a velocity of the moving component may be measured, and an acceleration then derived. From the derived acceleration, various parameters of the running engine may be calculated, including but not limited to, number of firing cylinders, rotational rate, and relative cylinder balance. These and other parameters may then be reported, such as through a display screen, to a user. The methods and devices disclosed herein may also generate recommendations for specific kinds of maintenance to an engine based on the results of parameter measurements and calculations, then report those recommendations to a user.

International Classification:

G01M 17/00
G06F 7/00
G06F 11/00

US Classification:

701 29, 701 34, 714100

Abstract:

Measurement data storage is triggered in response to occurrence of a user set condition with respect to one or more user-selected measured parameters, to thereby capture real-time monitored test data. In an application for a vehicle diagnostic tool, such as an engine analyzer, the measurements and attendant display may be provided during engine operation or actual vehicle operation. The tool software allows a user to specify any one or more of the measured parameters; and for any selected parameter, the user can identify an event with regard to the selected parameter. During the test, the processor executing the software captures measured parameter data, and the processor analyses the appropriate measured parameter data with respect to any and/or all user specified conditions. Triggering may be based on occurrence of an event or combinations of events. When triggered, the software will cause the tool to store some amount of captured data and/or pause the display to allow the user to analyze all available data.

International Classification:

H01Q 13/00
H01Q 15/14

US Classification:

343781CA, 343781 P, 343912

Abstract:

The present invention relates generally to the field of reflector-type antennas based on the offset Gregorian design having a substantially paraboloidal-shaped primary reflector and a substantially ellipsoidal secondary reflector displaced from the optical axis of the primary reflector. The first focus of the secondary reflector is substantially coincident with the focus of the primary reflector and a feed or detector is placed substantially at the second focus of the secondary reflector. A partially open shroud placed between the primary reflector and the secondary reflector is shown to result in reduced ground interference and improved antenna efficiency and sensitivity.

370252, 370253

Abstract:

A service provider network includes an automated support module that receives stream of network packets from subscribers and separates this streams into packet flows for analysis. The automated support module may be an intermediate device that examines each packet flow to detect subscriber characteristics for each subscriber. The automated support module may apply a set of analysis rules to the detected characteristics to aid diagnosis of reported or potential network errors.
