Latest Patents

One of Shepherd's latest patents is titled "Backscatter imaging using Hadamard transform masking." This invention involves an area x-ray source that utilizes alternating, masked, Hadamard transform patterns. The total backscatter signal from a target is recorded for each pair of corresponding masks. The difference in signal strengths for these masks provides a direct measurement of the Hadamard transform coefficient. An image of the target is then formed by performing an inverse discrete Hadamard transform on the complete matrix of coefficients.

Another significant patent is the "Bond strength measurement system using shock loads." This system offers a method for non-destructively testing the strength of bonded joints, particularly between composite components. The method activates a source of rapid surface pressure against a bonded assembly to create a shock load. This shock load generates both compression and tension within the bonded joint, allowing for the measurement of surface motions to determine the minimum strength of the joint. The impact magnitude can be adjusted to correspond with various load conditions.
