Systematic use of infrared imaging characterizes marks made on items and identifies the particular marking tool with better accuracy than use of visual imaging. Infrared imaging performed in total darkness eliminates shadows, glint, and other lighting variations and artifacts associated with visible imaging. Although normally used to obtain temperature measurements, details in IR imagery result from emissivity variations as well as thermal variations. Disturbing an item's surface texture creates an emissivity difference producing local changes in the infrared image. Identification is most accurate when IR images of unknown marks are compared to IR images of marks made by known tools. However, infrared analysis offers improvements even when only visual reference images are available. Comparing simultaneous infrared and visual images of an unknown item, such as bullet or shell casing, can detect illumination-induced artifacts in the visual image prior to searching the visual database, thereby reducing potential erroneous matches. Computer numerically controlled positioning of the toolmark relative to imaging sensors which use fixed focus optics with shallow depth of focus, varying focus distance and orientation systematically to construct a sequence of images, maximizes reliability of resulting images and their comparisons.

Identification, characterization and attribution of executable content within and across an enterprise infrastructure (e.g., hosts, subnets, routers, etc.) to provide situational awareness for cyber security for purposes of supporting proactive defense and response. Copies of executable content collected at one or more locations within an infrastructure (e.g., hosts, network edges, etc.) may be passed to a central analysis server whereby various characteristics of the executable content may be extracted or gleaned from the copies such as author marks (e.g., directory names), tool marks (e.g., compiler settings), behaviors (e.g., function extraction), patterns (e.g., byte sequences), text, and / or the like. The characteristics may be analyzed in various manners to build profiles of actors or organizations associated with (e.g., responsible for) executable content within the enterprise infrastructure.

The novel methods, apparatus and reworked rotary braking surface product, for example those exhibited on interior cylindrical braking surfaces of a cast iron brake drum, serve to replace manufacturing defects exhibiting residual tensile stresses and outwardly directed tool marks with smooth compressed braking surfaces in a final manufacturing stage.
