  • Publication number: 20080208797
    Abstract: Merging records from a first directory server and a second directory server to augment data from the first server with data from the second server. The records of the second server could contain only data augmenting the data from the record of the first server, or could contain duplicative data in addition to augmenting data, in which case only the augmenting data is merged with the data of the first server.

  • Patent number: 5315538
    Abstract: A system and method for automating signal tracking, estimation of signal parameters, and extraction of signals from sonar data to detect weaker signals. A maximum a posteriori (MAP) algorithm processing provides a track output of the signal which is used as a guide or template to provide optimal spectral integration on an unstable or frequency varying line. The present invention includes track integration, parameter estimation, signal track normalization, and sequential signal detection. The present invention partitions the input band into frequency subwindows. For each subwindow, the strongest signal is tracked, its parameters are estimated, and then the signal is normalized (removed) from the subwindow. This is repeated until the entire subwindow set is processed. Then the subwindows, now with their strongest signals removed, are recombined to form one input band. This aggregated procedure represents one processing pass.

  • Patent number: 4539752
    Abstract: An automatic sheet transport mechanism for precisely positioning a sheet relative to an automatic signature writing machine or the like is disclosed. A writing instrument is located vertically above a flat writing surface upon which the sheet rests and is movable into and out of engagement with the writing surface in a defined writing area. A sheet positioning device accurately positions the sheet laterally on the writing surface. A sheet feeding device is also provided for moving a single sheet from a stack of sheets and for advancing the single sheet to the sheet positioning device. A control device cyclically operates the transport mechanism so that the single sheet is moved by the sheet feeding device and sheet positioning device to the writing area of the writing surface where the writing takes place and thereafter the sheet positioning device is actuated to move the single sheet off of the writing surface so that the cycle can be repeated.
