In an exemplary embodiment of the present disclosure, a target marker for a firearm may comprise a module having a first portion, and a second portion electrically connected and coupled to the first portion. A light source may be disposed within and electrically connected to the second portion. An optical component may be coupled to the first portion at a first fixed distance from the light source. A circuit board may be electrically connected to the light source via at least one lead, wherein the lead may permit relative movement between the circuit board and the light source and may maintain a second fixed distance between the circuit board and the light source.

Techniques for tracing back a projectile to the projectile origin are described. A method includes detecting projectile track(s) in image(s). Each projectile track crosses multiple pixels in each image. The projectile track(s) correspond to projectile(s). The projectile track(s) in the image(s) are translated to traceback path(s). The traceback path includes a known location and a projectile origin (e.g. the location at which the projectile originated, also termed the shooter's location).

The present invention is a system and device which automatically measures and reports tactical information, allowing the user to efficiently communicate with command units. It is ideally a rifle mounted device, which can measure range, orientation, and position. The present invention can automatically report all tactical information, including enemy combatant positions.

The present invention relates to a method of marking and identifying a target, and in particular, a method of using a Directed Energy Weapon (DEW) to heat a target without damaging it so that the target may be clearly identified by detectors and systems using thermally sensitive imaging.

An optical system has an underlying device configured to provide output light. A transparent optical device optically coupled to the underlying device transmits light from the underlying device through the transparent optical device to display a scene. The transparent optical device includes detector elements formed in an active area to detect light portraying at least a portion of the scene. The underlying device has transparent regions formed in the active area to allow light to pass through from the underlying device to a user. The optical system further includes an image processor that processes images produced using light detected by the detector elements to identify a specific instance of light in the scene. The image processor causes display elements in the active area of the transparent optical device to display an indicator, in the scene, correlated to the specific instance of light.

A system and method for determining a performance metric based on a discharge event of a firearm includes a first inertial measurement unit (IMU) and a first event detection module. The first IMU is disposed on a first firearm and senses movement including at least one of accelerations and rotations. The first event detection module can receive a plurality of first input signals from the first IMU indicative of the movement. The first event detection module can identify an occurrence of a first shot discharge of the first firearm at a shot time based on the plurality of first input signals; determine a first orientation of the first firearm at the shot time; determine a second orientation of the first firearm at a first time before the shot time; compare the first and second orientations; and assign a first stability index based on the first and second orientations.

This invention provides impact detection and vehicle cooperation to achieve particular goals and determine particular threat levels. For example, an impact/penetration sensing device may be provided on a soldier's clothing such that when this clothing is impacted/penetrated (e.g., penetrated to a particular extent) a medical unit (e.g., a doctor or medical chopper) may be autonomously, and immediately, provided with the soldiers location (e.g., via a GPS device on the soldier) and status (e.g., right lung may be punctured by small-arms fire).

Electro-optical sighting systems and methods are provided. One example includes a optical transmitter configured to emit an infrared beam along an optical path toward a target, a beam director positioned in the optical path and having a plurality of optical elements configured to direct the infrared beam and to collect reflected infrared radiation from reflection of the beam from the target, a focal plane array detector configured to receive reflected infrared radiation from the beam director, an optical phased array (OPA) positioned in the optical path between the optical transmitter and the beam director, and a controller operatively coupled to the OPA and configured to direct the OPA to defocus the infrared beam to broaden a field of view of the optical transmitter for active illumination, and focus the infrared beam to narrow the field of view of the optical transmitter for range determination and/or target designation.

Devices, systems and methods for providing firearms, including handguns, with infrared sights and a camera which can be held in one shooter's hand. The camera can send live video which can display a target to a portable display, such as a smart phone, smart watch or smart glasses, that is held in another hand of the shooter, so that the shooter remains out of harms' way if the target is armed.
