An improved Rail Adaptor System/Rail Accessory System (RAS) which attaches to a firearm. The rail is top opening, modular, and free floats the barrel. Provided is a rigid, lightweight, strong platform for mounting firearm accessories. Heat transmission from the barrel assembly to the user is limited. The user is also protected from ventilated gases originating from the operating system. A quick detachable top rail section is provided so that that gas system may be easily accessed. This removable top section of the rail is what makes this device unique because the RAS may be installed without removing the barrel, gas system, front sight base, flash hider or the barrel nut. The herein described RAS is adaptable to a wide variety of firearms with the use of conversion parts. The top rail “returns to zero” on reinstallation allowing the remounting of various optics and electronic gun sites without the need to realign them.

An object of the present invention is, when determining a line-of-sight vector of a subject, to identify a three-dimensional position of a pupil center or corneal reflection center thereof. The line-of-sight vector is determined by measuring a distance from a camera to the pupil center or corneal reflection center of the subject using a two-dimensional CMOS distance image sensor by a light time-of-flight method and obtaining position information of the pupil center and corneal reflection center of the subject using the distance image sensor. If a position and a direction of the camera are identified, a camera-pupil center vector is determined from image information of the pupil center of the subject. Since the camera-pupil center distance has been measured, a pupil center position in a three-dimensional space is determined from the above information. Combining this with two line-of-sight vectors determines a position where line-of-sight vectors intersect, or a view-point.

A system and method that guides a device to an object using periodically adaptive guidance. The guidance and control system creates a reconstructed line-of-sight (LOS) vector to avoid system destabilization associated with small angle approximations during high bore sight engagements. The guidance system adaptively estimates the periodic maneuver of evasive objects with a set of harmonically balanced Kalman filter banks. The Harmonically Balanced Kalman filter banks generate a set of probabilities that weight the effect of each individual Kalman filters on a resultant guidance command signal. The guidance command signal generated by the system acts perpendicular to the object LOS. The guidance and control system uses vectored proportional navigation guidance laws, optimal proportion navigation laws and periodically adaptive augmented guidance laws to generate a guidance command signal to supply to an autopilot.

A system of independently oriented sighting devices includes a first sighting device (120) and a second sighting device (110). Upon aligning a line of sight of the first sighting device (12) with a target object (130), the first sighting device transmits a reference signal over a communications link (140).
