  • Publication number: 20120265659
    Abstract: Aspects described herein provide techniques for providing information on real estate loans. First user input indicating a request for identifying at least one exception for data elements associated with at least one real estate loan may be received. The at least one exception may be representative of a conditionally acceptable data element value or an unacceptable data element value. Data for the at least one real estate loan may be compared with business rules data concerning unconditionally acceptable values of the data. The at least one exception may be identified based upon the comparison. Second user input indicating one of a verification of the at least one exception for the conditionally acceptable data element value or a change of the value for the at least one exception for the unacceptable data element value may be received.

  • Publication number: 20110139876
    Abstract: An imaging module includes a mounting frame, a scanning module, a lens, a number of illumination lights, a first circuit board and a second circuit board. The mounting frame has a bottom wall, a first sidewall and a second sidewall located at opposite sides of the bottom wall. The first and second walls define a receiving space which opens at a top end of the mounting frame. The second circuit board has a decoding element and is electrical connected with the first circuit board. The second circuit board covers the top end of the receiving space.

  • Patent number: 7495934
    Abstract: The adaptive synchronous rectification control circuit and its controlling method for a power converter are provided. The proposed control circuit having a transformer with a primary and a secondary sides, a switch coupled to the primary side and a synchronous rectification transistor (SRT) coupled to the secondary side and having a parasitic diode includes a preprocessor receiving a source-drain voltage of the SRT and outputting a first signal, and a control set receiving the first signal, a pre-determined voltage and a pulse signal synchronized to the switch and generating a second signal synchronized to the switch for controlling the SRT, in which a selection of the pre-determined voltage makes the source-drain voltage of the SRT ranged from 0 to a conducting voltage of the parasitic diode of the SRT.
