Abstract: An automated technique compares two sets of documents (such as two source codebases) to automatically determine documents within each set that are similar to one another. The technique constructs a matrix relating pairs of documents from the first and second sets of documents to lines that occur in both documents in each of the pairs of documents. A similarity score is calculated for each of the pairs of documents based on the lines from the matrix.

Abstract: The present invention relates to a load bearing apparatus, and more particularly, to a passive exoskeleton whereby a load may be placed on the passive exoskeleton and thereby transfer weight of the load from the passive exoskeleton to a ground surface. The passive exoskeleton comprises a rigid body member for attaching proximate a portion of a user's body, a sliding rod attached with the body member, and a ground surface engage-able foot analog attached with the sliding rod. When a user places a load on the body member, weight of the load from is transferred from the body member, through the sliding rod, and into the foot analog, causing the passive exoskeleton to support at least a portion of the load.
