  • Patent number: 11892470
    Abstract: A chronograph system with a frame, at least two sensors, an accelerometer, and a processor module. The frame is configured to removably couple to a barrel of a firearm. The sensors are attached to the frame and are configured to detect a projectile as the projectile passes each sensor. A first of the sensors may be separated from a second of the sensors by at least three inches. The accelerometer is attached to the frame and configured to track an orientation of the barrel. The processor module is communicatively coupled to the sensors and to the accelerometer and may be configured to receive timestamps from the sensors and the orientation of the barrel from the accelerometer, use the timestamps to determine a velocity of each projectile, and analyze the velocity data and the orientation of the barrel to aid a user in adjusting a scope of the firearm.

  • Patent number: 7739823
    Abstract: A fire control system that includes an array of photodiode elements. For each element of the photodiode array, there is a specific optical path in the atmosphere leading from the laser to a target and back from the target to the element. Accordingly, each element of the detector array can be regarded as if illuminated by a distinct light source. For short time periods (in the range of tens to hundreds of milliseconds) the shape or spatial distribution of the refractive-index irregularities does not significantly change, and the irregularities drift with the atmospheric wind. By measuring the signal fluctuations by any element of the photodiode array, it is possible to compute the crosswind velocity. By comparing signal fluctuations patterns of two or more elements it is possible to define the wind direction and to determine the turbulence strength value.

The PDD is coupled to a computer and comprises a multitude of photodiodes and associated circuits, the photodiodes being evenly spaced and arranged to form a frame that can be mounted on the computer so as to surround the computer video display. When a “shot” is fired from the LPD, the crosshair projection is interrupted briefly. The PDD determines the position of the four crosshair intersections and reports them to the computer which, in response, generates the video signals that form the resolved aimpoint on the screen, matching the LPD aimpoint to the video image. Further, the tracking system determines the rotation of the LPD over a range of at least 10 degrees clockwise or counter-clockwise.

  • Patent number: 6362872
    Abstract: Method and device for thermal imaging and rangefinding. In one form the device comprises an optical system including a first aperture and first, second and third optical paths each passing through the first aperture. A polarizer positioned to segregate the first and second optical paths is capable of receiving polarized radiation reflected from the target and transmitted through all portions of the first aperture stop. A polarization modifier is positioned between the first aperture and said polarizer; and a beam splitter, sensitive to spectral differences between the polarized radiation and the thermal radiation, is positioned along the first optical path between the first aperture and said polarizer.

  • Patent number: 6347762
    Abstract: The Multispectral-Hyperspectral Sensing System (MHSS) comprises a control center, a surveillance platform and at least one weapon battery with known sensing and destroying capabilities. The control center has access to pre-existing information relating to the target scene and potential targets, although not necessarily current, as well as the capabilities and limitations of the available weapons. This pre-existing information is communicated to the surveillance platform to be used in collecting hyperspectral/multispectral image data of the target scenery and to derive from the collected image data the relevant current target data subset. The derived data subset is then down-linked to the control center, which performs further processing to make it useful to the selected weapon. The weapon receives the target signature update from the control center and, in response, performs a significantly more precise strike at the selected target than based just on the a priori knowledge base.

  • Patent number: 6265704
    Abstract: A laser tracking system steers a beam of laser energy which is dithered in two directions to scan the surface of a moving object. A laser energy detector detects laser energy reflected from the target. Reflected energy is filtered to distinguish dither frequencies for signals in both directions, which signals are independently analyzed to determine the location of the target in relation to the laser beam. A bias signal is generated which causes the beam of laser energy to be steered toward a surface radius to be steered toward a surface with the largest compound curvature within the trackers, field-of-regard, to the target, to the tracked location on-target, or modified signals steer a portion of the beam to an optimum track location on target while offsetting most of the beam's energy to a second engagement location on target. Also, a track testing system is capable of monitoring a laser beam focused on a missile and determining the effective laser engagement on a spinning target.

  • Patent number: 6260466
    Abstract: Assessing the accuracy with which a round fired from a gun hits an intended target is achieved and alignment of the gun is corrected by monitoring the target with an image sensor which is associated with a computer enabling a frame by frame analysis and comparison of the fired round's trajectory with computer-generated alternative trajectories.

  • Patent number: 6247259
    Abstract: A method for the fire control of flat trajectory weapons, which comprises the steps of measuring the target range and cross wind velocity along the intended projectile trajectory prior to firing the weapon and, using the know ballistic equations of the projectile, determining the expected vertical and horizontal deflection of the projectile and adjusting the weapon sight to compensate for said deflections.

  • Patent number: 6199794
    Abstract: A multi-color, multi-pulse laser target designator is disclosed in which the target is illuminated with pulses of preselected colors and interpulse spacings so as to uniquely identify the target. Inter-pulse spacing may be varied down to an arbitarily small spacing by virtue of the use of pulses of differing colors, thereby increasing countermeasure resistance due to the difficulty of a target detecting and duplicating inter-pulse spacing. Pulse elongation is provided in one embodiment to provide prolonged illumination of the target so as to permit increased homing accuracy for optically guided weapons.
