  • Patent number: 8063346
    Abstract: Systems and methods are provided for projecting a virtual image of an object. A projector mounted on the object for projecting a light beam. A photographic plate is provided that includes an interference pattern imprinted onto at least one surface, wherein the interference pattern manipulates the light to form a hologram beam such that a detector detecting the hologram beam detects a virtual image of the object that has a light signature at a greater intensity than a light signature of the object.
    Type: Grant

  • Patent number: 7106374
    Abstract: A closed-loop vision system is disclosed that utilizes a concept known as Dynamically Reconfigurable Vision (DRV), which is adaptive image sensing driven by a computer or human operator's response to changing scenery. The system reduces the amount of irrelevant video information sensed and thus achieves more effective bandwidth and computational resource utilization, as compared to traditional vision systems. One or more reconfigurable photodetector arrays sensitive to either visible, infrared or ultraviolet radiation are present in the DRV system. These photodetector arrays feature on-chip means for spatial and temporal data reduction implemented through multiple independently controllable, time-correlated, frequently overlapping windows on the photodetector array that may be programmed according to their size, location, resolution, integration time, and frame rate. All photodetector array windows are dynamically reconfigurable in real time on a frame-by-frame basis.

  • Patent number: 6636861
    Abstract: A method of uploading and processing database files of varying file format and column ordering from a client machine to a server machine for storage in a centralized database having a predetermined file format and column ordering is provided. The method includes configuring a database information profile, which includes the file format and column ordering of the database file to be uploaded. Optionally a test upload is performed and upload feedback is received by the client machine. Upon a successful test upload, the database information profile and corresponding database file are uploaded to the server machine. The uploaded database file is parsed line-by-line and column-by-column and mapped into the centralized database in accordance with the fixed format and column ordering of the centralized database.
