Filed:

Oct 6, 2000

Appl. No.:

09/680676

Inventors:

Jin Yu - Mountain View CA, US
Jun Chen - Sunnyvale CA, US
Hseuping Chen - Milpitas CA, US

Assignee:

Martsoft Corporation - Santa Clara CA

International Classification:

G06F017/60

US Classification:

705 27

Abstract:

A method and system for providing virtual access to product/service information distributed across heterogeneous catalog systems is disclosed. The method and system include subscribing a first catalog server to at least a portion of the information stored on one or more remote catalog systems, thereby creating a subscribing catalog server. Thereafter, a replication process is performed to synchronize information on the subscribing catalog server with the subscribed information on the remote catalog systems. A user may then use the subscribing catalog server to search and browse the synchronized information, thereby providing one site for viewing information from multiple catalog servers.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H03M 7/00

US Classification:

341107, 714758

Abstract:

A method and apparatus are described for constructing efficient Slepian-Wolf codes for inputs that do not have uniform probability distributions, and for channels which are not symmetric. Whereas conventional Wyner-Ziv video compression systems assume symmetrical probability distributions and ignore the marginal distribution component, the invention incorporates the marginal distribution component by combining the marginal distribution and conditional distributions as input to a transform that generates a symmetrical output, which is then fed into the conventional density evolution method.

US Classification:

370392, 370245, 370395, 709238

Abstract:

One embodiment of the present invention provides a system that identifies network switches along a path. During operation, the system receives an address of a source node and an address of a destination node. The system maintains a set of topology information for a network. The system further simulates a data packet originated at the source node and destined for the destination node. During the simulation, the system determines whether a current-hop node performs layer-3, layer-2, or sub-layer-2 switching. The system sends a query to the current-hop node over a separate control channel to determine the status of the current-hop node and discover a next-hop node. The system then receives a reply. The system determines the next-hop node based on the reply and sets the next-hop node as the current-hop node.

International Classification:

G06F 11/00

US Classification:

714 15, 714 13

Abstract:

Methods and apparatus, including computer program products, implementing and using techniques for resolving a hang condition in a distributed environment including a client computer and server computer(s). A network thread is provided, which passes requests from the client computer to the one or more server computers and responses from the server computers to the client computer. Worker thread(s) are provided on the server computers. The worker threads receive requests from the network thread, execute the requests, and pass responses to the requests back to the network thread. A request is sent from the client computer to a server computer through the network thread. A timer associated with the request is started on the client computer. The timer specifies a pre-defined time period for receiving a response to the request. When no response has been received within the pre-defined time period, a reset request is sent to the server computer.

Abstract:

Two methods of fabricating a MEMS scanning mirror having a tunable resonance frequency are described. The resonance frequency of the mirror is set to a particular value by mass removal from the backside of the mirror during fabrication.

International Classification:

H01L 21/336

US Classification:

438257000

Abstract:

MTJ stacks formed using prior art processes often fail because of shorts between the pinned layer and the top electrode. This problem has been overcome by depositing a protective layer on the MTJ sidewalls followed by an inter-layer dielectric. Then planarizing until the protective layer is just exposed. Finally, an etching (or second CMP) process is used to selectively remove the protective layer from the top surface of the cap layer.

International Classification:

H04L 12/56

US Classification:

370389

Abstract:

Among other disclosed subject matter, a computer-implemented method for forwarding data includes receiving a data unit that is on a route toward a destination. The data unit is associated with a first limit value regarding forwarding of the data unit. The method includes causing the data unit to be associated with a second limit value at least equal to the first limit value. The method includes forwarding the data unit to a next recipient in the route, the data unit associated with the second limit value.

Abstract:

A two-step targeted tumor therapeutic method is described comprising nanocarrier with prodrug encapsulated thereto and prodrug activating enzyme. The enzyme is either encapsulated in nanocarrier, or not encapsulated, or synthesized in the tumor. With the method, the prodrug released from the nanocarrier is activated by the enzyme mainly in the tumor.
