Aspects provide a surveillance device that is autonomous and includes data processing components which, in real time, process values measured by measurement components and transmit the results of processing operations to logging components for logging, the measurement components including elements that measure values of parameters representative of a mechanical environment and elements that measure values of parameters representative of a climatic environment. Aspects also include restitution components that enable restitution of the logged data and results of processing operations at any time.

Disclosed is a novel system, and method for matching a spent firearm cartridge. The method starts with applying a directed self-assembly (DSA) process to produce a nano-scale pattern on a tip of a firing pin for a firearm. The DSA process including: a) disposing a neutral substrate on the firing pin; b) lithographically placing two or more base polymer chains on the neutral substrate, at least two of the two or more base polymer chains being different lengths, so that the two or more base polymer chains align end-to-end in an alternating structure, and c) extracting at least one of the two or more base polymer chains leaving at least one of the base polymer chains remaining thereby forming a randomly oriented pattern. Next, the randomly oriented pattern is used as blocking mask to form a randomly oriented metallization pattern.

A non-destructive device that measures the accuracy potential and relative ballistic coefficient of projectiles, by placing the object tested within a swirling vortex having both a rotational and vertical vector, hovering the projectile essentially above the device, and essentially unencumbered by any stator. A perfectly balanced object hovers and turns at a high rate about its long/vertical axis without contact with the device.

A parts inspection system for automated video inspection for quality control processes. The inspection system is particularly adapted for rotationally symmetrical workpieces including small arms ammunition cartridges. The system provides a first array of light sources oriented radially around the workpiece path presenting zones of illumination on the workpiece at discrete radial positions. A second illuminator is in the form of linear arrays of light emitting elements oriented along linear arrays. A camera oriented to observe images of light provided by the first and second arrays records video images of the workpieces for use in resolving criteria of acceptable and unacceptable parts. An escapement mechanism moves acceptable and rejected parts into different parts streams.

A machine vision system for automatically identifying and inspecting objects is disclosed, including composable vision-based recognition modules and a decision algorithm to perform the final determination on object type and quality. This vision system has been used to develop a Projectile Identification System and an Automated Tactical Ammunition Classification System. The technology can be used to create numerous other inspection and automated identification systems.

A testing system for a shaped charge of a perforating gun, the testing system including a housing; a casing assembly located inside the housing; a perforating gun having at least one shaped charge, the perforating gun being located within the casing assembly; a sample material located within the housing, and in direct contact with the casing assembly; a wellbore accumulator in direct contact with the casing assembly and configured to supply a first fluid, at a wellbore pressure, inside the casing assembly; and a formation accumulator in direct contact with the sample material and configured to supply a second fluid, at a formation pressure, on the sample material.

A method involves inscribing a unique ballistic information number (BIN) on a bullet in process of manufacture, recording the BIN in a network-connected database, recording identity of a person who purchases the bullet at point-of-sale, and associating the person who purchases the bullet in the network-connected database with the BIN inscribed on the bullet and recorded in the network-connected database.
