Abstract: A method of generating a topographic map of a region of a body for the manufacture of a body fitting article to be fitted to the region of the body. The method allows for the resultant topographical map of the body feature to be coupled to an anatomical and functional datum on the body. The method involves use of a contact probe which is configured to generate positional data which defines the surface it is drawn across. The method comprises the steps of urging a contact probe towards the outer surface of the body such that the contact probe is touching the outer surface of the body or separated from the outer surface of the body only by a barrier layer which is flattened against the outer surface of the body by the probe. The contact probe is drawn over the region of the body where the body fitting article is to be located such that the contact probe generates 3D positional data of the surface of the outer surface of the body in the region of the body where the body fitting article is to be located.

Abstract: System and method for detecting objects in geospatial images, 3D point clouds and Digital Surface Models (DSMs). Deep Convolution Neural Networks (DCNNs) are trained using positive and negative training examples. Using a rotation pattern match of only positive examples reduces the number of negative examples required. In DCNNs softmax probability is variant of rotation angles. When rotation angle is coincident with object orientation, softmax probability has maximum value. During training, positive examples are rotated so that their orientation angles are zero. During detection, test images are rotated through different angles. At each angle, softmax probability is computed. A final object detection is based on maximum softmax probability as well as a pattern match between softmax probability patterns of all positive examples and the softmax probability pattern of a target object at different rotation angles.

Abstract: A laser beam dump is provided. The laser beam dump may include a housing that has a plurality of connected walls defining an atypical or asymmetrical polygonal prism. When viewed in longitudinal cross-section, the asymmetrical polygonal prism housing defines a general hexagon shape. A chamber is defined by the housing and a highly reflective cone is positioned therein. The inner surfaces of the housing are formed from a highly absorptive material with respect to electromagnetic energy in the form of a laser beam. When an laser beam enters the chamber of the beam dump, it contacts the highly reflective cone outer surface and it nearly fully reflected to the absorptive walls of the housing. This reduces the reflection scatter of light from the first contact with the cone.
