    Abstract: A breakaway base and upper-separation joint for use with highway luminaire supports. The breakaway base, circular in cross section, has a lower-base section with a first rim, an upper-base section with a second rim, a split-ring retainer, and a perimeter band. The split-ring retainer captures the first rim of the lower-base section and the second rim of the upper-base section. The perimeter band encircles the split-ring retainer. In response to a vehicle impact with the upper-base section, the perimeter band fractures, causing disjunction of the split-ring retainer and allowing the upper-base section to separate from the lower-base section. Alternatively, the breakaway base is radial-spoked when viewed from above and has a first plurality of rims on the lower-base section, a second plurality of rims on the upper-base section, a plurality of retainer segments to engage and capture the first and second plurality of rims, and a plurality of fasteners to secure the retainer segments against the rims. In response to a vehicle impact with the upper-base section, the fasteners fracture, freeing the retainer segments and allowing the upper-base section to separate from the lower-base section. The upper-separation joint has an upper pole section, a lower pole section with a duct, fastening means for connecting the upper pole section to the lower pole section, plugging means for securing the fastening means, and separation means connected at a first end to the plugging means and at a second end, through the duct, to the lower-base section. Upon separation of the breakaway base due to vehicle impact, the separation means removes the plugging means, disengaging the fastening means and separating the upper pole section from the lower pole section.

    Abstract: A support post for a roadside sign that is designed to break easily when struck by a car, pivot up, and allow the car to pass under it. The hinge or pivot point is directly behind the vertical center of area of the sign, thereby eliminating the effects of wind which caused problems with the prior art design. GISTATEMENT OF GOVERNMENT INTERESTThe present invention arose in the course of a government contract and may be manufactured and used by or for the government of the United States without the payment of any royalties thereon or therefor.

    Abstract: A railroad track inspection system and method for facilitating inspection of a rail component while traveling on the railroad track. The railroad track inspection system includes an optical path protection device for a protective window for optical sensors of an optical inspection system when it becomes contaminated with dirt, dust, mud, grease, and other contaminants that block or obscure an optical path of the sensors. The optical path protection device eliminates the need for a human operator to perform the periodic cleaning of the protective window by using a clear film with an automated advancement mechanism for providing clean film, as needed, for keeping the optical path of the optical sensors unobstructed and clear.

    Abstract: A method for detecting a watermark signal in digital image data. The detecting method includes the steps of: computing a log-polar Fourier transform of the image data to obtain a log-polar Fourier spectrum; projecting the log-polar Fourier spectrum down to a lower dimensional space to obtain an extracted signal; comparing the extracted signal to a target watermark signal; and declaring the presence or absence of the target watermark signal in the image data based on the comparison. Also provided is a method for inserting a watermark signal in digital image data to obtain a watermarked image. The inserting method includes the steps of: computing a log-polar Fourier transform of the image data to obtain a log-polar Fourier spectrum; projecting the log-polar Fourier spectrum down to a lower dimensional space to obtain an extracted signal; modifying the extracted signal such that it is similar to a target watermark; performing a one-to-many mapping of the modified signal back to log-polar Fourier transform space to obtain a set of watermarked coefficients; and performing an inverse log-polar Fourier transform on the set of watermarked coefficients to obtain a watermarked image.
