As best seen in FIGS. 14 and 15, the visual processing or augmentation module

As best seen in FIG 11, the laser range finder module B and the camera module C are configured to slide into the respective bays 102, 104. In embodiments, the modules B and C are secured in place by threaded fasteners 106 passing through clearance openings 108 in the modular enclosure A and threadably engaging aligned openings 110 in the modules B and C.

The laser range finder module B includes an optical transmitter/receiver pair 120 configured to emit an optical signal, such as a pulse encoded signal, and sense a return signal reflected from a target, wherein a distance to the target is calculated based on the time of flight of the emitted signal and the return signal, as would understood by persons skilled in the art.

The battery compartment portion G includes one or more battery compartments, each configured to receive one or more battery cells 123 (see FIG. 13). Each compartment is covered with a removable battery cap 122. In embodiments, the battery compartment portion G includes two battery compartments. In embodiments, the unit 100 is configured to be powered by one battery at a time, with a second battery compartment being provided to allow for extended run time via manual and/or automatic switchover when the cell in one compartment is depleted.

The camera module C includes a plurality (three in the embodiment illustrated) of camera assemblies 124. In embodiments each camera assembly is prefocused to a predetermined distance. For example, in embodiments, the camera module C includes three camera assemblies which are pre-focused to varying distances, e.g., 100 m, 250 m, and 500 m. In embodiments, the camera assemblies 124 may be miniature camera modules of the type used in mobile devices which comprise an image sensor (e.g., CMOS, CCD, or near infrared (NIR) sensor, or the like) and a lens assembly. In embodiments, the camera assemblies 124 also have different focal lengths, e.g., wherein the 100 m camera has a wider field of view/lower magnification, the 250 m camera has an intermediate field of view/lower magnification and the 500 m camera has a narrower field of view/higher magnification.

An optical magnifier/multiplier L is detachably coupled to a pivot assembly M (see FIG. 10) which, in turn, is coupled to the upper surface of the main housing E. The pivot assembly M includes a base 126 which is secured to the upper surface of the main housing E. A mounting shoe fastening arm 128 is pivotally coupled to the base 126 via a hinge assembly 130. The mounting shoe fastening arm 128 includes a fastening element 132, such as a dovetail shoe receptacle or the like. The fastening element 132 detachably receives complementary fastening element 133 (see FIG. 12) such as a dovetail shoe. The hinge assembly defines a pivot axis 134 which extends in a direction parallel to a long. axis of the unit 100 and parallel to an optical axis 136 of the optical magnifier L. In embodiments, the optical magnifier L has a magnification in the range of 4x to 10x, preferably 6x. In this manner, the operator can selectively pivot the magnifier L to the deployed position wherein the optical axis 136 of the magnifier L is in optical alignment with an optical axis 138 of the reflex sight module D, e.g., when it is desired to view a magnified image of the view through the reflex sight, e.g., for extended viewing/targeting range. Alternately, the operator can selectively pivot the magnifier L to the stowed position wherein the optical axis 136 of the magnifier L is out of optical alignment with the optical axis 138 of the reflex sight module D, e.g., when it is desired to view targeted scene through the reflex sight directly. For example, stowing the magnifier L allows the operator to use the reflex sight directly which may make it easier to engage a target in certain situations, such as when attempting to engage a target in flight, such as a drone or other unmanned aerial vehicle. The pivoting movement between the deployed and stowed position is indicated by the arrow 137 appearing in FIG. 8.

In embodiments, a latch assembly 140 is configured to releasably secure the fastening arm 128 in the stowed position. In embodiments, a switch assembly 142 is provided for sensing whether the magnifier L is in the stowed or deployed position, as will be described in further detail below. The switch assembly 142 is operably coupled to processing electronics on the main control board J. Alternately, the position of the magnifier may be determined using a proximity sensor. For example, the magnifier L or the mounting shoe fastening arm 128 may carry a magnet and a proximity sensor such as a Hall effect sensor or a magnetic reed switch may be disposed in the housing E such that an output signal is generated when the magnifier L is in the stowed position.

For example, as shown in FIG. 7B, which is equally applicable to the embodiments appearing in FIGS. 1-19, the sensor 142 may be a proximity sensor such as a Hall effect sensor or a magnetic reed switch. A magnet 143 is carried on the arm 128 so that the magnet 123 is in proximity with the proximity sensor switch 142 when the magnifier L is in the deployed position and is moved out of proximity with the switch 142 when the magnifier L is pivoted to the stowed position. Alternately, the switch 142 can be a mechanical switch incorporating a spring biased actuator as would be understood by persons skilled in the art. In either case, the switch 142 is operably coupled to processing circuitry on the main control board J, which monitors the switch state by detecting its open or closed condition and thereby sensing the position of the magnifier L.

In embodiments, the hinge assembly is separable or detachable to that the magnifier L can be completely removed from the fastening arm 128 when it is not desired to use the magnifier L, as shown in FIG. 10.

The main housing E has a height 144 which is configured to allow the unit 100 to function as a riser to provide increased height between the rail the sight than conventional systems. This provides a better "cheek well' or "sight plan" when looking thought the reflex sight and is particularly advantages for an operator wearing bulky equipment such as a night vision googles, gas mask or other nuclear, biological, and chemical (NBC) or chemical, biological, radiological, and nuclear (CBRN) equipment. This is in contrast to conventional systems wherein a user wearing such equipment may be required to position their head in an awkward in order to look thought the sight.

As best seen in FIG. 12, the reflex sight module D includes a reflex sight housing 146 which houses a digital display 148 and one or more optical elements designated generally as 149, including one or more prisms, wedges, lenses, waveguides, and/or other reflective, refractive, and/or diffractive optical elements configured direct images from the display 148 to the eye of the operator. In embodiments, the one or more optical elements incudes a beam combiner 150 or similar optical element such as a partially reflective mirror, dichroic mirror, or the like, or a waveguide which is configured to reflect a portion of the rays from the display 148 to the user's eye while also being sufficiently transparent to permit rays from the targeted scene to pass therethrough to provide a direct view of targeted scend. In this manner, the output of the display 148 is superimposed onto the operator's view of the targeted scene. The display 148 is in operable communication with display driver electronics associated with the visual processing module K.

In embodiments the display 148 is configured to display a video image acquired by on of the cameral modules 124. In embodiments, the range to target distance as determined by the laser range finder B is used by the processing electronics on the main control board J, which may be implemented in hardware, software, firmware, or any combination thereof, to activate which ever camera is needed to provide a full field of view of the imaged scene in the digital display 148.

In embodiments, when the optical magnifier L is in the stowed position the display output of the digital display 148 as detected by the sensor 142, the output of the digital display is changed to match the optical power of the magnifier L. The change in output of the digital display may be accomplished by camera selection of the appropriate camera in the camera module C, a digital zoom function implemented in the video processor module K, or a combination thereof.

In embodiments, the output of the display 148 includes visual indicia such as an electronic reticle 152 (see FIG. 6) and preferably includes a plurality of reticle types including but not limited to one or more types of dot reticles, cross hair reticles, and so forth. In embodiments, the type of reticle is selectable via the on board menu system. In embodiments, the unit 100 and video processing module K supports user-configurable reticle styles which can be programmed by the user and wirelessly transmitter to the unit via a wireless (RF) interface 257 (see FIG. 13).

In embodiments, the electronic reticle is a disturbed reticle showing the ballistic solution and point of aim data for a given target, e.g., based on range to target and other ballistic factors. In embodiments, the position of the electronic reticle 152 on the display is dynamically adjusted based on a ballistic solution calculated based on range and/or other ballistic information to improve alignment with the target, thereby enhancing accuracy and increasing the likelihood that the trajectory of a fired projectile will intersect with the position of the target. Other indicia for display using the display 148 include but are not limited to target range indicia based on output of the laser range finder module B, current time or mission duration, navigation data, sensor readings, battery status or battery life remaining, environmental data, warnings or alerts, data pertaining to situational awareness information, and other mission-relevant information.

The above description of the fire control system with integral reflex sight 100 in reference to FIGS 1-19 is equally applicable to FIGS. 1A-19A, which description is incorporated by reference here, except as specifically stated otherwise herein.

FIG. 1A is an isometric view the fire control system with integral reflex sight 100', taken generally from the front and left side. The unit 100' differs from the unit 100 described above in that it further includes a connector assembly including a connector housing 271 (left side in the illustrated embodiment) having a connector 270 which is configured to receive a System A payload programming remote control unit 272 for sending program information to the weapon to determine the distance at which the round will air-burst. The remote control unit 272 includes a cable 274 having a connector end 276 which engages with the connector 270. In embodiments, the connectors 270, 276 are shown as complementary circular connectors, e.g., Fischer style connectors such as a 3 pin or 4 pin Fischer style connectors, although other connector types are also contemplated. It will be recognized that although a left side connector 270 receiving programming remote control is illustrated, right handed and ambidextrous embodiments are also contemplated.

In certain embodiments the remote control unit 272 includes a plurality of push buttons 275a-275d. In the illustrated embodiment, the button 275a is configured to actuate the laser range finder module B to initiate ranging to determine the distance to the target for calculating a ballistic solution. The button 275b is configured to program a programmable airburst round. The buttons 275c and 275d are configured such that each button press increments the distance at which the airburst round will detonate up or down, respectively, by a preselected incremental distance, such as in 1 meter increments. In embodiments, the programmed detonation distance is overlaid on the display 148 and/or displayed on the secondary display 174.

In one programming mode, the detonation distance for programming a programmable round is set initially by default to the target distance as calculated by the laser range finder module B. The detonation distance can then be increased or decreased in increments such as 1 meter to be greater or less than the calculated distance. For example, in the case of an enemy target which is hiding behind cover, the operator can program the airburst round to detonate at a distance just beyond the target (i.e., further past the enemy's position) so that the round bursts above or past the cover, thereby releasing shrapnel or fragmentation in a way that maximizes the impact on the enemy, even if they are shielded behind an object.

In another programming mode, the detonation distance for programming a programmable round is incremented based on the firing position of the operator using the buttons 275c and 275. In embodiments, to streamline programming in this alternative mode, a hold the buttons 275c and 275c may include a hold function where holding the button 275c or 275d increases or decreases the value rapidly and/or in larger increments, such as 10 m, 50 m, 100 m, etc.

The unit 100' also differs from the unit 100 described above in that the battery selector lever 154 has been oved from the left side to the right side.

Referring now to FIGS. 20 and 21, there is shown a third embodiment fire control system with integral reflex sight 100" wherein the reflex sight assembly includes an integral front iron (mechanical) sight 282 (see FIG. 20) and an integral rear iron (mechanical) sight 284 (see FIG. 21).

The front sight 282 includes a pivot plate 286 which is pivotally secured to a front surface of the housing of the reflex assembly D. The pivot plate 286 is secured in pivotable fashion via a threaded fastener 288 and is pivotable about a pivot axis 292 as indicated by the arrow 293 appearing in FIG. 20. In this manner the front sight 282 can be pivoted between a deployed position as illustrated and a stowed position where it is out of the view through the reflex sight D when not in use. A post 290 is coupled to the pivot plate which projects into the field of view of the direct view optics when pivoted to the operable position.

The rear sight 284 includes a rear sight housing 294 having a slot 297 formed therein. A rear sight member 295 includes a post 296 which is coupled at its lower end to a pivot rod 298 and which has a notch or aperture 300 at its upper end. The illustrated embodiment depicts a U-shaped notch, although other configurations are contemplated, such as a V-notch, an aperture or ring, and so forth. The pivot rod 298 passes through an opening in the reflex sight housing and includes a knob 304 at its distal end. The knob 304 is manually rotatable between a deployed position as illustrated and a stowed position where it is out of the field of view of the reflex sight D when not in use. During pivoting movement, the post 296 runs in the slot 297 to allow pivoting movement of the rear sight 274 about a pivot axis 302 as indicated by the arrow 304 appearing in FIG. 21. Either or both of the front and rear sights 282, 284 may have a contrast feature to enhance visibility, e.g., on the post 290 and/or the notch or aperture 300, which may be, for example, a feature that is painted with a contrasting color, luminescent paint, and so forth.

The inclusion of the iron sights 282, 284 is advantageous in that is ensures continued aiming accuracy in the event of failure of the fire control system with integral reflex sight. For example, the unit 100" were to become inoperative, e.g., due to battery depletion, damage, or a failure of the disturbed reticle display hardware or software, the operator could fall back on the iron sights 282, 294, aligning them within the direct-view optics to maintain effective targeting. This redundancy enhances reliability in critical scenarios, allowing for accurate engagement of targets even when the magnified and/or enhanced aiming features of the unit 100" system are compromised.

While the fire control system with integral reflex sight embodiments 100 and 100' are shown and described above without iron sights, it is contemplated that the iron sights 282, 284 of the unit 100" may also be incorporated into the embodiments 100 and 100'. In particular, the iron sights 282 and 284 appearing in FIGS. 20 and 21 may likewise be integrated into the systems 100 and 100' described above to provide a backup aiming mechanism in the event of failure of the magnified/disturbed sighting system. Such modifications fall within the scope of the present disclosure, and any features described with respect to one embodiment herein may be combined with any other embodiment unless otherwise indicated.

The invention has been described with reference to the preferred embodiment. Modifications and alterations will occur to others upon a reading and understanding of the preceding detailed description. It is intended that the invention be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
