  • Patent number: 7725438
    Abstract: A method and apparatus for creating backup files by creating an overhead segment for each file that is to be backed up and creating a data segment containing the data that is to be backed up for each file. After creating overhead segment and the data segment, the overhead segment is placed into an overhead stream and the data segment is stored in a memory. The overhead segment is also positioned in the overhead stream with a pointer that identifies the location of the data within the memory. As such, the backup file comprises a data segment and an overhead stream.

  • Patent number: 7634511
    Abstract: Various methods and systems for presenting a logical view of a database backup are disclosed. One method involves querying a database recovery manager for logical identifiers that correspond to physical backup pieces generated during a backup. The method uses the logical identifiers to display a backup view to a user. The backup view identifies logical database components that are available to be restored.

  • Publication number: 20080208619
    Abstract: A method for evaluating a healthcare information system includes first determining a first specification for the healthcare information system. The first specifications may include healthcare profile data for specifying a profile of a healthcare provider, technology profile data for specifying a profile of technology resources, and performance data for measuring the benefits associated with performance indicators of the healthcare information system. Then, an evaluation is determined from the first specification, which may include system performance values. Additionally, characteristic values for performance indicators may be presented to the user. Next, a second specification is then determined by specifying to the user that at least some values of the first specification may be changed. Then, an evaluation for the healthcare information system is determined for the second specification.

  • Patent number: 7349480
    Abstract: A method and system for multiline transmission in communications systems are described. A transmitter (1102) performs MIMO pre-processing (1104) on symbol vectors. A signal vector associated with the symbol vector is transmitted. A receiver (1106) performs MIMO post-processing (1108) on the received signal vectors to minimize the effects of crosstalk on pairs of lines in the multiline communications system.

  • Publication number: 20060109779
    Abstract: A method and system are disclosed for improving the performance of a multiline transmission system by using one or more split-pair receivers in a multiline communications system to identify crosstalk on a pair of transceivers coupled to the split pair receivers, wherein each split pair receiver receives a signal including the crosstalk from each transceiver and provides a corresponding signal vector to a post processing unit, and performing MIMO post-processing on signal vectors received at a receiver from each transceiver and each split-pair receiver while minimizing crosstalk on pairs of lines in the multiline communications system with a frequency equalizer.

  • Publication number: 20050273298
    Abstract: According to an embodiment of the invention, a system and method for performing simulations is provided. Using parallelism-in-systems, the method decomposes a larger problem into several smaller partitions. A series of iterations is performed until the waveforms exchanged between the partitions converge. Approximate pre-view solutions of strongly coupled partitions are introduced to reduce the number of iterations required for convergence. These approximate pre-view solutions are introduced before the simulations occur. Once the waveforms converge, the simulation has determined a solution.

  • Publication number: 20050133211
    Abstract: A technique is disclosed for evaluating and monitoring performance of a heat exchanger system. Operating parameters of the system are monitored and fouling factors for heat transfer surfaces of the exchanger are determined. Trending of fouling may be performed over time based upon the fouling factors, and a model of fouling may be selected from known sets of models, or a model may be developed or refined. Fluid treatment, such as water treatment regimes may be taken into account in evaluation of fouling. An automated knowledge based analysis algorithm may diagnose possible caused of fouling based upon sensed and observed parameters and conditions. Corrective actions may be suggested and the system controlled to reduce, avoid or correct for detected fouling.

  • Patent number: 6803548
    Abstract: A heat treatment apparatus for making a heat treatment while estimating temperatures of objects-to-be-processed that can estimate correct temperatures of the objects-to-be-processed. A reaction tube includes heaters and temperature sensors, and receives a wafer boat. A controller estimates temperatures of wafers and temperatures of the temperature sensors in zones in the reaction tube corresponding to the heaters by using the temperature sensors and electric powers of the heaters. Based on relationships between estimated temperatures of the temperature sensors and really metered temperatures, functions expressing the relationships between the estimated temperatures and the really metered temperatures are given for the respective zones. The functions are substituted by the estimated wafer temperatures to correct the estimated wafer temperatures.
