Abstract: A method for conserving energy in a computing unit and transferring data between the computing unit and an external source. The computing unit is in a power saving mode. The method includes receiving at the computing unit a request from an external source, determining which components of the computing unit are required to respond to the request, selectively activating, from the power saving mode, the components of the computing unit necessary to respond the request, and responding to the request using the selectively activated components of the computing unit. As one example, the computing unit may comprise a laptop, and the external source may comprise a PDA, and the request may include a request from the PDA to retrieve data from or store data on the laptop.

Abstract: A business process involves manually entering data from an invoice into a first database by a first person. The database includes a status indicator having various states. The invoice entry is audited by a second person who manually enters a subset of the data into the database. The subset is matched with the data entered by the first person and unmatched entries highlighted. The auditor may re-enter only data which he has entered. The invoice is then returned to the first person who may re-enter only data which he has entered or cancel the invoice. After there are no unmatched entries, the first person posts the data to a second database.

Abstract: An improved total-reflection x-ray fluorescence (TXRF) apparatus using a doubly-curved optic is presented for use in detecting foreign matter on surfaces, for example, semiconductor wafers. The apparatus includes an x-ray source, a doubly-curved x-ray optic for diffracting and focusing the x-rays, a surface onto which at least some of the diffracted x-rays are directed, and an x-ray detector for detecting resultant x-ray fluorescence emitted by any foreign matter present on the surface One or more apertures may be provided for limiting the dispersion angle of the x-rays. The crystal or multi-layer doubly-curved optic typically adheres to Bragg's law of x-ray diffraction may be curved to a toroidal, ellipsoidal, spherical, parabolic, hyperbolic, or other doubly-curved shape. An apparatus for diffracting x-rays is also presented.

Abstract: The management and use of replicated distributed transactions is facilitated. A distributed synchronous transaction system protocol is provided to manage the replication of distributed transactions for client application instances. The distributed synchronous transaction system allows transactions to be replicated without having the client application instances be aware of other instances to receive the transaction. Further, if a failure occurs during processing of a distributed replicated transaction, the distributed synchronous transaction system manages the recovery of the failure.

Abstract: A technique is provided for encoding macroblocks of a frame of a sequence of video frames initially employing luminance data only to analyze temporal redundancy of the macroblocks within the frame. Upon deciding to code at least one macroblock as a non-intra macroblock, the technique includes considering whether to switch the coding decision for the at least one macroblock from non-intra to intra by evaluating chrominance data of the at least one macroblock. The evaluating of the chrominance data can include determining whether chrominance difference data, obtained by comparing chrominance values of a current macroblock with a reference macroblock, is greater than a user set chrominance difference threshold, and if so then the technique includes switching the macroblock coding decision. As a further qualification, the switching might occur only if the chrominance difference data is also greater than the corresponding luminance difference data.

Abstract: A cooling system and method, and a cooled electronics assembly are provided employing a thermal spreader having an inner chamber evacuated and partially filled with a liquid. A phase separator is disposed within the thermal spreader to at least partially divide the inner chamber into a boiling section and a condensing section, while allowing vapor and liquid to circulate between the sections. A heat extraction assembly is disposed at least partially within the inner chamber to extract heat therefrom. When the thermal spreader is coupled to a heat generating component with the boiling section disposed adjacent thereto, liquid within the thermal spreader boils in the boiling section, producing vapor which flows upward from the boiling section and causes liquid to flow into the boiling section from the condensing section, thereby providing circulatory flow between the sections and facilitating removal of heat from the heat generating component.

Abstract: A computer display system, method and article of manufacture are presented allowing a user to interactively arrange two-dimensional windows for display in three dimensions on a two-dimensional display screen of the computer system. A window manager associated with the display screen is configured to respond to a user's selection of a frame edge of a window, e.g., using a third mouse button, by rotating the window from a two-dimensional depiction to a three-dimensional depiction. Rotation of the window occurs on an edge frame opposite to the selected edge frame and the rotation angle is related to the magnitude that the user drags the pointing device after selection of one edge frame of the window to be swung. In a similar manner, multiple windows can be swung for three-dimensional viewing and simultaneous display within the display screen.

Abstract: Assignment of a unique address identifier to a partition of a computing environment is provided by extending the applicability of hunt groups. A single-member hunt group is initiated to provide an alias address (e.g., hunt group ID) which is associated with the partition of the computing environment. A token (or token and password) facilitates the association between the alias address and the partition. Subsequent communication between the partition and a fabric switch of the computing environment will use the alias address as a source or destination address identifier, thereby uniquely identifying the partition.

Abstract: A technique is provided for aligning and formatting multi-operand pixel data, for example, within a pixel formatter of a graphics engine for a set-top box system. The technique includes, in one embodiment, obtaining pixel data of a first alignment and a first format for conversion to a second alignment and a second format. The pixel data undergoes pre-alignment where the first alignment of the pixel data is changed to a bit zero alignment, after which the pixel data is reformatted from the first format to the second format. The reformatted pixel data is post-aligned to change from bit zero alignment to the second alignment. In one embodiment, the pixel data is source pixel data or pattern pixel data, while the second alignment and the second format are alignment and format of destination pixel data.

Abstract: Various components are provided to manage a clustered environment. These components include a System Registry that provides a global data storage; a Configuration manager that stores data locally on nodes of the clustered environment and globally within the System Registry; a Liveness component to provide status of communications paths of the cluster; a Group Services component that provides services to one or more other components of the clustered environment; and a Resource Management component that communicates with one or more resource controllers of the clustered environment. Each of the components of the clustered environment has one or more data and/or functional dependencies on one or more other components of the environment. However, relationships between the components are created such that the data and functional dependencies form an acyclic graph (i.e., a cycle of dependency relationships is avoided).

Abstract: Techniques for establishing contact between a first node and a second node in a communication system having a plurality of nodes. Upon a failure of an attempt by the first node to contact the second node, the first node contacts a 3rd party node, which in turn attempts to contact the second node on behalf of the first node. The first node's initial attempt to contact the second node can be verified by the 3rd party node, thereby avoiding an unjust detriment to the first node. Multiple retries or 3rd party nodes can be used to attempt contact on behalf of the first node. Responsiveness of nodes can be measured, and subsequent penalties can be assessed, as a result of their unresponsiveness.

Other aspects of the invention include a method for fabricating the connector and the sleeve used in the connector.
