Appl. No.:

12/893468

Inventors:

Richard V. Hom - Troy MI, US
Eric M. Nelson - Durham NC, US
James C. North - Virginia Beach VA, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/00

US Classification:

707694

Abstract:

The invention is directed to off-peak and just-in-time (JIT) retrieval of directory information to reduce network traffic and load on directory servers and/or data sources by requesting only the information that is currently needed from the directory server, while subsequently updating the directory information during an off-peak period in the case that the directory information retrieved in a JIT manner is outdated. In these embodiments, a hybrid integrator operable with an integration directory capable of retrieving directory information in a JIT manner provides this functionality.

US Classification:

707769, 707E17014

Abstract:

The invention is directed to just-in-time (JIT) retrieval of directory information to reduce network traffic and load on directory servers and/or data sources by requesting only the information that is currently needed from the directory server. In the invention, a request handler operating with the directory server provides this capability. Specifically, the request handler and directory server are configured to receive a request for directory information from a client and to determine a location corresponding to a set of current attribute values for responding to the request. The request handler retrieves the set of current attribute values from at least one of the following: the directory server and an external source. A set of current attributes is returned to the client from the directory server. The request handler propagates information in a JIT manner so that only the information that will be currently used by the client is propagated across the network.

US Classification:

709219

Abstract:

The invention is directed to just-in-time (JIT) retrieval of directory information to reduce network traffic and load on directory servers and/or data sources by requesting only the information that is currently needed from the directory server. In the invention, a wrapper operating with a directory server and an application programming interface (API) provides this capability. The wrapper is configured to receive a request from a client and to determine a location corresponding to a set of current attribute values for responding to the request. The wrapper retrieves the set of current attribute values in a JIT manner from at least one of the following: the directory server and an external source. A set of current attributes is returned to the client from the wrapper. By propagating information in a JIT manner, only the information that will be currently used is propagated across the network.

Abstract:

A closed-loop torque demand power steering system suitable for large off-highway and other vehicles has no mechanical linkages or hydraulic connections entering into the driver's cab. A torque demand signal is produced electronically without any separate electromechanical torque sensor. Upon starting, the system provides synchronization between steering and steering wheels without initial corrective motion of either member. During operation the direction of the steered wheels does not drift relative to the position of the steering wheel. The circuit includes protection against spurious steering signals that might otherwise occur if the steering is moved back and forth mechanically on a transition boundary of a position sensor. In the event of certain types of failure of its primary steering system it automatically changes over to an open-loop secondary steering system that is controllable by the same steering wheel, and that has components in common with the primary system.
