  • Publication number: 20130054187
    Abstract: A method of adaptively positioning a scanner [10] within a three-dimensional scene identifies an optimal next position for the scanner [40] based on analysis of a data point cloud that mimics the scanned portion of the scene. Occluded areas [38] are delineated from scan data and scans made at different locations in the scene are registered to a reference four-coordinate system. The fourth coordinate corresponds to the hue observed by the scanner at each data point.

  • Patent number: 8341068
    Abstract: The present invention discloses a method and apparatus for generating and evaluating ideas within an organization through an idea market. It includes an automatic price-setting mechanism that modifies the share-price at the same instant that a trade is made, yet without the assistance of a market maker or a queue of orders. The instant price-setting is achieved by assuming a pre-defined relationship between the quantity of shares in the order and the average share price for that order. This relationship is the price-quantity function. The present invention also includes a mechanism of weighted parameters to modify the share-price in addition to pure supply and demand. The parameters can be adjusted over time in a neural network to optimize the relationship between the share price and the prediction of the actual idea value.

  • Patent number: 8093039
    Abstract: A surface coating comprises a primer coat that permits adhesion of eukaryotic cells thereto, and a plurality of macromolecular structures attached to the primer coat. At least some of the macromolecular structures have a cell-resistant character, meaning that cells generally will not adhere to them. The macromolecular structures are distributed across an area of the primer coat so that the surface coating permits adhesion of the eukaryotic cells to the primer layer and resists the adhesion of non-eukaryotic cells. Typically, the primer coat comprises a self-assembled polymeric monolayer and the macromolecular structures comprise nanoscale hydrogels. Such surface coatings may be formed on articles of manufacture for insertion into the body, such as orthopedic devices.

  • Patent number: 7847933
    Abstract: Linear chirped pulses in a Raman excitation scheme provide selective excitation of only one target transition (single mode) in a molecule without disturbing any other transitions or molecules. Selectivity is guaranteed by the adiabaticity of the pulse excitation, which allows manipulation by only a resonant mode while leaving all of the other modes unperturbed. This in turn allows for enhanced imaging or spectroscopic analysis of a sample that contains one or more of the molecules.

  • Patent number: 7529384
    Abstract: A product and process for extracting hidden data from a stego-image that has been subjected to scaling attacks are disclosed. The hidden data extraction method of the present invention retains the one-to-one mapping of the stego-image blocks to the corresponding blocks in the scaled image. When the stego-image is scaled down, the block size for extracting the hidden data is reduced proportionally. When the stego-image is scaled up, the block size for extracting the hidden data is increased proportionally. The total overall number of blocks of pixels to be examined is kept constant between the scaled image and the stego-image. The hidden data extraction method can be combined with any existing block-DCT based data hiding method to provide an overall method for dealing with scaling attacks. Both the extraction method and the combined method can be implemented in software and stored within a machine-readable medium.
