System and method for remote full field three-dimensional displacement and strain measurements

Patent Number: 9,046,353

AbstractA method and system for measuring full field deformation characteristics in three dimensions of a body upon which a pattern of visible marks has been applied. The method includes receiving images of the pattern of marks from at least two digital video cameras as the specimen deforms. A computer processor identifies the centroids of each of the two camera images of the body in a first frame, matches the centroids of the marks in the two images, and generates a three-dimensional representation of the centroids based on the two images, and repeats these steps for the images from the two cameras in a subsequent frame. The computer processor calculates the displacement vector between a three dimensional representation of the centroids and the subsequent three dimensional representation of the centroids, and calculates full field displacement and strain fields based on the displacement vector.

Patent Grant Time

This patent had a slower than average grant time compared to others in this category.

Patent grant time can be influenced by many factors. Activities within the USPTO that are beyond the control of patent attornies can influence grant time, but short grant times can also indicate well-written patents and dedicated efforts to respond rapidly to USPTO office actions with strong arguments. Shorter grant times are preferable, and the scores for this section are inverse measures — higher scores are better.

Patent Claims

This patent has fewer claims compared to others in this category.

The number of claims in a patent is correlated with its strength. Because greater claim counts increase the cost of a patent, more claims can indicate the importance an applicant assigns to a patent. Importantly, some may elect to file claims across multiple patents. A higher score in this metric indicates more claims, relative to others in this category.

Citations From Other Patents

This patent has received far fewer citations from other patents, than others in this category.

Citations from other patents are an important measure of the significance of a patent. More citations indicate that other technologies build on a patent. Higher scores in this metric are better, and indicate more citations from other patents.

Citations to Other Patents

This patent referenced many more citations to other patents, than others in this category.

A lower number of citations to other patents can be a sign of diminished patent strength. More citations indicate dependence on more other technologies. Higher scores in this category are better, and indicate fewer citations to other patents.

Proximity to Basic Research

0%

0%

This patent has much less proximity to basic research compared to others in this category.

Proximity to basic research is measured by comparing the number of citations to non-patent literature among a cohort of patents. Because most non-patent citations are primary research papers, a higher count indicates greater proximity to basic research.
