| 20120026973 | HANDOVER DATA INTEGRITY IN A WIRELESS DATA NETWORK - A method and apparatus for handover data integrity of a mobile station in a wireless data network with a plurality of wireless network service areas. The method and apparatus includes initiating handover by a mobile station, identifying a target access service network (ASN) for handover from a serving ASN. When the target ASN is identified, receive a data integrity capability from the target ASN, and determine whether a direct data delivery mode is available as a data integrity mode. When a direct data delivery mode is available, direct data delivery is performed with the data associated with the service flow from the serving ASN to the target ASN. | 02-02-2012 |

| 20120068658 | System And Method For Setting Machine Limits - A system and method for setting machine limits include setting a limit for a machine parameter, setting a temporal operating range for the machine, and setting a temporal step. The machine is operated over the operating range and the machine parameter is measured. A first new limit for the machine parameter is set based at least in part on the measurements over the operating range. The operating range is advanced by the temporal step, and the machine parameter continues to be measured. Another new limit for the machine parameter is set based at least in part on the measurements over the operating range after the operating range has been advanced. | 03-22-2012 |

| 20090240724 | ENVIRONMENT DEFINITION FILES FOR AN ENVIRONMENT DEFINITION SYSTEM - An Environment Management System (EMS) provides on-demand instances of environments for testing hardware and/or software configurations. In various embodiments, the EMS includes a processing engine that handles parsing and execution of commands in a definition file that express the lifecycle of a testing environment. Accordingly, the EMS provides flexibility to end users in the way that environments are configured and deployed. An environment definition file is provided that may contain a standard set of scripts for implementing the lifecycle of the environment, along with any custom logic specific to a user or customer. | 09-24-2009 |

| 20090252330 | DISTRIBUTION OF STORAGE AREA NETWORK ENCRYPTION KEYS ACROSS DATA CENTERS - Efficient mechanisms are provided for transferring key objects associated with disk logical unit numbers and tape cartridges from one data center to another data center. A request is received to transfer a source data center key object from a source data center to a destination data center. The source data center key object corresponds to a data block, such as a disk logical unit number (LUN) or a tape cartridge, maintained in a storage area network (SAN) and includes a unique identifier, an encrypted key, and a wrapper unique identifier. The encrypted key is decrypted using a source data center key hierarchy. Key information is transmitted from the source data center to the destination data center. A destination data center key object is generated using a destination data center key hierarchy. | 10-08-2009 |

| 20120116703 | METHOD AND APPARATUS FOR ENHANCED SPATIAL BANDWIDTH WAVEFRONTS RECONSTRUCTED FROM DIGITAL INTERFEROGRAMS OR HOLOGRAMS - The present invention discloses a method and an apparatus to compute a complex wavefield, referred to as the object wave o, by means of measuring the intensity signal resulting from the interference of the said object wave with a second wave termed the reference wave. The second wave r is assumed to have some non-vanishing mutual coherence with the said object wave o. The reference wave can be obtained from a source or from the object wave itself. The wave may be emitted from sources of variable degree of coherence and can be scattered waves, but also light-emitting molecules, matter waves such as electron beams or acoustical sources. The disclosed method relates to the said “non-linear method” (NLM). The innovation resides in the fact that the NLM improves considerably the bandwidth of the wavefront reconstructed from off-axis interferograms and holograms obtained in a single shot. The advantage is the significant improvement of the resolution of the images obtained from the reconstructed wavefront, i.e. amplitude and phase images. The said method also suppresses the artifacts resulting from the intensity recording of interferograms and holograms. The method is general in the sense that it can be used for any interferometric measurement, provided that it satisfies the simple requirement that the intensity of the reference wave is larger than the intensity of the object wave, and that the object wave modulated by the reference is confined to at least a quadrant of the spectrum. The disclosed method applies to interferometry, holography in optics, electron waves and acoustics. In particular, it can be implemented in phase, fluorescence, luminescence, electron and acoustic microscopy. | 05-10-2012 |
