US Patent:

7546398, Jun 9, 2009

Filed:

Aug 1, 2006

Appl. No.:

11/461461

Inventors:

Karyn T. Corneli - Austin TX, US
Christopher J. Dawson - Arlington VA, US
Timothy M. Waters - Hiram GA, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 3/00

US Classification:

710 38, 712 26

Abstract:

The Distributed Virtual I/O Tool replaces dedicated VIO server LPARs by distributing the virtual I/O functions across several application LPARs connected by a high-speed communication channel. The physical I/O devices are distributed across available LPARs. The Distributed Virtual I/O Tool assigns each I/O request to an appropriate I/O device. The Distributed Virtual I/O Tool monitors each I/O request and reassigns I/O devices when performance drops on a specific device or when a device is no longer available.

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

F41C 1300

US Classification:

434 16

Abstract:

A small arms firing effects simulator utilizes a modular construction to egrate with the magazine of a weapon such as a rifle. The modular design resembles the ammunition clip and houses an expendable plastic coated plurality of pyrotechnic charges. An electrical control circuit is also housed within the module and serves to interface the pyrotechnic charges with the firing of the weapon, including semi-automatic and automatic firing as well as disabling the weapon when all rounds have been fired.

International Classification:

G02B 1700

US Classification:

350443

Abstract:

A laser diode optical system includes a laser diode having non-circular beam emitted from a diode emitter junction and having a peak energy centered on an optical axis, a collimating lens spaced from the laser diode with its focus at the laser diode on the optical axis to intercept direct energy from the laser diode and produce a central collimated beam on the optical axis, a paraboloidal reflector coaxially disposed about the laser diode emitted beam and collimating the portion of the emitted beam outside the included angle subtended by the lens, the collimated energy from the reflector being refracted through the periphery of the collimating lens to direct the collimated energy from the reflector into a hollow convergent-divergent conical beam coaxial about the central beam, a plurality of spaced energy diffusing elements on a surface of the lens intercepting and diffusing direct laser diode energy impinging the lens, and also intercepting and diffusing energy from the reflector, producing a spaced pattern of overlapping diffused beams forming a generally toroidal beam coaxially disposed about the central beam.

International Classification:

G06Q 10/06
G06Q 30/00

Abstract:

A method and system for determining work ticket priority is provided. The method includes enabling a work ticket for a work assignment associated with an entity. The work ticket is assigned an initial priority value. Relevant data from multiple sources is associated with the work ticket and an updated priority value is requested. In response, multiple priority scores for the work ticket with respect to additional work tickets are published to an enterprise service bus (ESB) and an aggregate score for work ticket is calculated from the multiple priority scores.

International Classification:

H04W 12/06
H04W 12/08
G07C 9/00
H04L 29/06

Abstract:

Embodiments described herein provide approaches for associating a user identity to a wireless signal based on information received at an access point. Specifically, when a first user presents a set of user credentials to a physical access point, his/her profile is accessed to authenticate the first user. A set of wireless signals emanating from one or more wireless devices operated by the first user is also received at the physical access point and associated with the first user. Information about the first user may then be broadcast and accessed by a second user (e.g., via his/her mobile device) in proximity to the first user and in receipt of the set of wireless signals associated with the first user.

International Classification:

G06F 11/07
G06N 5/02

Abstract:

A computer-implemented embodiment heals an information technology (IT) system. A cognitive computing hardware system receives an error history log that describes a history of past errors that have occurred in the IT system. The cognitive computing hardware system receives a listing of alternative IT systems that have been predetermined to have a same functionality as the IT system and that have a history of experiencing one or more errors currently being detected in the IT system. The cognitive computing hardware system receives a record of real-time events, which are external to the IT system and which impact a performance of the alternative IT systems. The cognitive computing hardware system generates a prioritized set of solutions to overcome the one or more errors currently being detected in the IT system, based on the error history log, the listing of alternative IT systems, and the record of real-time events.

International Classification:

H04L 12/24
H04L 12/911

Abstract:

One or more processors compute a number of times that a string of text is identified within an online news feed. One or more processors compute a score for the string of text, at least in part, by multiplying the number of times the string of text is identified within the online news feed by a number representing a uniqueness of the string of text. In response to a determination that the score exceeds a first configurable threshold value, one or more processors generate an electronic notification. The electronic notification alerts of an anticipated change in one or more computer hardware capacity requirements of a networked computer system.
