  • Patent number: 6831991
    Abstract: A system and method that efficiently, accurately, and simply detect reliably least-significant-bit (“LSB”) embedding of a secret message in randomly scattered pixels. The system and method apply to both 24-bit color images and 8-bit grayscale or color images. Many commercial steganographic programs use Least Significant Bit embedding (LSB) as the method of choice to hide messages in 24-bit, 8-bit color images and in grayscale images. They do so based on the common belief that changes to the LSBs of colors cannot be detected because of noise that is always present in digital images. By inspecting the differences in capacity for lossless (invertible) embedding in the LSB and the shifted LSB plane, the present invention reliably detects messages as short as 1% of the total number of pixels (assuming 1 bit per sample). The system and method of the present invention are fast, and they provide accurate estimates for the length of the embedded secret message.

  • Patent number: 6626569
    Abstract: An image-based quality assurance (IBQA) system is provided for performing quality assurance testing of a medical linear accelerator photon beam. The IBQA system includes an imaging phantom integrated with an automated image analysis system. The imaging phantom comprises a set of fixed and rotatable reference objects which, when radiographed, set the orientation of the phantom, determine magnification factors and measure spatial distortions. The imaging phantom includes a chamber for inserting a radiographic film to record an image of the photon beam. The sampled image is digitized and made available to the automated image analysis system for measuring quality assurance parameters from the sampled image. The measured beam quality parameters are compared with baseline parameter values to determine whether they fall within prescribed specifications.

  • Patent number: 6592098
    Abstract: An improved microvalve device is configured to provide a more robust and durable operation to withstand the demands of various operating environments. The microvalve may comprise a valve seat and a diaphragm, with the diaphragm operated by an external actuator device, such as a bladder, through various mechanisms of actuation, such as direct and indirect mechanisms, that are separate from the microvalve. Through use of the various mechanisms of actuation, the actuator device is configured to apply forces on the diaphragm to suitably move the diaphragm to open and close the microvalve. The valve seat and diaphragm can be configured to provide the microvalve with a plurality of openings configured to permit flow thereinbetween. In addition, the microvalve may be configured to facilitate uni-directional or bi-directional flow.

  • Patent number: 6455831
    Abstract: A foveal image sensor integrated circuit comprising a plurality of CMOS active pixel sensors arranged both within and about a central fovea region of the chip. The pixels in the central fovea region have a smaller size than the pixels arranged in peripheral rings about the central region. A new photocharge normalization scheme and associated circuitry normalizes the output signals from the different size pixels in the array. The pixels are assembled into a multi-resolution rectilinear foveal image sensor chip using a novel access scheme to reduce the number of analog RAM cells needed. Localized spatial resolution declines monotonically with offset from the imager's optical axis, analogous to biological foveal vision.

  • Patent number: 6438905
    Abstract: An energy dissipation apparatus for installation in structural frames to mitigate seismic effects comprises a scissor-jack system of braces with an energy dissipation device such as a viscous, viscoelastic, or hysteretic damper, or an active or semi-active device, connected between opposing pivot joints of the scissor-scissor jack system. The scissor jack system magnifies displacement so that energy is dissipated more effectively by the damper. Open bay, diagonal, and alternative installation arrangements with respect a structural frame are disclosed.

  • Patent number: 5508348
    Abstract: A composite is formed wherein particles of a conductive polymer are uniformly distributed within a processable non-conductive polymer. In the method of the invention, an inverted emulsion is formed by dispersing an aqueous solution of oxidant in an organic solvent comprising a host polymer and an oil-soluble surfactant. A monomer whose polymerization yields a conductive polymer which is dissolved in a solvent miscible with the organic solvent of the emulsion is then added dropwise to the emulsion with agitation. The composite is separated from the emulsion and the precipitate is washed and dried.
