Countermeasure simulating structures may include (a) a base and (b) one or more separated combustible tracks fixed to the base's surface. The combustible tracks may include thermite and/or other combustible material. The combustible tracks may be shaped to simulate countermeasure flares deployed by a vehicle (e.g., a jet). The countermeasure simulating structure may be incorporated into a countermeasure simulating system that includes (a) an infrared and/or optical sensing system (e.g., like those included in missiles) and (b) a simulator mount holding the countermeasure simulating structure. Countermeasures may be tested in such systems by: (a) arranging an infrared and/or optical sensing system to receive infrared energy and/or visible light emitted by the countermeasure simulating structure; (b) igniting the combustible material of the combustible track such that combustion of the combustible material moves along the combustible track; and (c) determining whether the infrared and/or optical sensing system tracks infrared energy and/or visible emitted by the combustion.

Before a person can use any weapon, such as a gun or a rifle, effectively, the sight must be aligned to the barrel through a zeroing process. Various embodiments discloses a firearm zeroing app for automatically determining the adjustments of a weapon equipped with an optical sight. The system can utilize a mobile device to take a picture to capture an image of a shot group. Then, using the app, the system automatically calculates the datum of the shot group, the centroid of the shot group, and the distance for adjustment of the sighting device to accurately fire the firearm. In another embodiment, the mobile device can be configured to capture and record the image of firing of the firearm so that the app automatically captures as a video the images of the shots fired to establish the shot group and automatically analyzes the projectile's flight path data.

We disclose herein an infra-red (IR) device comprising a substrate comprising an etched cavity portion and a substrate portion; a dielectric layer disposed on the substrate. The dielectric layer comprises a dielectric membrane which is adjacent, or directly above, or below the etched cavity portion of the substrate. The device further comprises a reflective layer on or in or above or below the dielectric membrane to enhance emission or absorption of infrared light at one or more wavelengths.
