Description

FIELD OF THE DISCLOSURE

The present disclosure relates to the field of firearm components, and more particularly to an improved forend for a firearm and a firearm-mountable light having an improved switch assembly.

BACKGROUND

Firearm-mountable lights that include on-off switches are known in the art. Examples of these lights include the TLR series of lights manufactured and sold by Streamlight, Inc. of Eagleville, Pa., U.S.A., which is the applicant of the present application. Some of these switches are small and difficult to locate for users, especially in high-stress and/or low-visibility scenarios. In addition, forends (i.e., forward-located grip portions) that assist a user in holding a firearm during use are known in the art. Some of these forends are difficult to hold on to during use of the firearm, thus creating safety and efficiency problems for the user.

There is a need for improved firearm-mountable lighting devices that overcome the drawbacks present in the relevant prior art devices. There is also a need for improved forends for firearms that overcome the drawbacks present in the relevant prior art devices.

DETAILED DESCRIPTION

The ensuing detailed description provides exemplary embodiment(s) only, and is not intended to limit the scope, applicability, or configuration of the herein disclosed embodiment(s). Rather, the ensuing detailed description of the exemplary embodiment(s) will provide those skilled in the art with an enabling description for implementing the exemplary embodiments in accordance with the present disclosure. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention, as set forth in the appended claims.

To aid in describing the disclosure and/or invention as claimed, directional terms may be used in the specification and claims to describe portions of the present disclosure and/or invention (e.g., upper, lower, left, right, etc.). These directional definitions are merely intended to assist in describing the embodiment(s) and claiming the invention, and are not intended to limit the disclosure or claimed invention in any way. In addition, reference numerals that are introduced in the specification in association with a drawing figure may be repeated in one or more subsequent figures without additional description in the specification, in order to provide context for other features.

It should be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or that intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, it should be understood that no intervening elements are present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.).

In embodiments described herein or shown in the drawings, any direct electrical connection or coupling, i.e., any connection or coupling without additional intervening elements, may also be implemented by an indirect connection or coupling, i.e., a connection or coupling with one or more additional intervening elements, or vice versa, as long as the general purpose of the connection or coupling, for example, to transmit a certain kind of signal or to transmit a certain kind of information, is essentially maintained. Features from different embodiments may be combined to form further embodiments. For example, variations or modifications described with respect to one of the embodiments may also be applicable to other embodiments, unless noted to the contrary.

In applications in which it is desirable or necessary to illuminate a scene while handling a firearm, a light may be mounted to the firearm so that the operator need not handle the firearm and light separately. Such firearm-mountable lights may be mounted to a rail, forend, barrel, or any other portion of the firearm. While holding a firearm, especially a long gun such as a rifle or shotgun, it may be difficult for a user to quickly locate and actuate the on/off and/or any adjustment switches that comprise the firearm-mountable light, especially in high-stress and/or low-visibility scenarios. It is the desire of Applicant to disclose a firearm-mountable light having one or more switches that improve upon the prior art.

Referring now generally to FIGS. 1-12, one embodiment of a firearm-mountable light 20 according to the present disclosure will be described in detail. FIGS. 1 and 2 show an exemplary long gun in phantom lines, in the form of a shotgun 2 having a receiver 4 that includes an ejection port 6, a trigger 8, a stock 10, a barrel 12, a forend 14, and a magazine tube 16 onto which the forend 14 is installed, as would be appreciated by a person having ordinary skill in the relevant art. FIG. 1 shows the light 20 according to the present disclosure in an unmounted configuration with respect to the shotgun 2, and FIG. 2 shows the light 20 mounted on the magazine tube 16 of the shotgun 2.

When a user is holding a typical long gun (e.g., shotgun 2), one hand is typically in the vicinity of the receiver 4 so that one or more fingers can access the trigger 8, and the other hand typically holds the forend 14 of the gun. In the example shown in FIGS. 1 and 2, the forend 14 of the shotgun 2 includes a grip portion to comfortably accommodate the user's forward-located hand. As shown in FIG. 2, the light 20 according to the present disclosure serves as a replacement for the stock forend 14, and includes both a grip portion 23 that serves as a replacement for the forend 14 and all functional components of a flashlight, as will be described in detail below. As will also be described in detail below, the light 20 may be easily activated by the user's forward-located hand, since this hand will already be in contact with the light 20. In this embodiment, the light 20 is held in place on the shotgun 2 using the same retaining ring (not shown) used to hold the stock forend 14 on the shotgun 2, as would be appreciated by a person having ordinary skill in the art. In this embodiment, the forend 14 is removed from the magazine tube 16 by loosening the stock retaining ring and then sliding the forend 14 forwardly in the direction shown in FIG. 1 until it has been removed from the magazine tube 16. The light 20 is then installed over the magazine tube 16 by sliding it onto the magazine tube 16 in the opposite direction, as also shown in FIG. 1.

Known firearm-mountable lights are not integral with a forend or other grip-containing portion of the firearm. Known firearm-mountable lights also typically have one or more small switches which may be difficult to locate with one's forward hand without looking at the side of the firearm, which would require the user to take their gaze off of a potential or intended target and possibly put them in harm's way or distract them from the target. Some prior art devices also have only a single switch, which in some case may be awkwardly placed for some users, specifically since single-switch placement may not be ideal for both right- and left-handed shooters and users having different hand/arm sizes. The light 20 according to the present disclosure addresses these issues in several ways. First, the light 20 includes a pair of switch assemblies 40, 50 located on opposite sides of the light 20 for redundancy, each of which is adapted to turn a light assembly 38 of the light 20 on and off. Second, the switch assemblies 40,50 have extended lengths 43,51 and specially-designed pressing mechanisms—as will be discussed below in greater detail—such that either switch assembly 40,50 may be pressed—and the attached light assembly 38 thus activated—by pressing along any portion of the length 43,51 of either of the switch assemblies 40,50 with a depressing force sufficient to actuate the switch assembly 40,50 (e.g., move the respective switch assembly from its open state to its closed state). It should be understood that an adequate depressing force will first have to compress the relevant portion of the respective boot 42,54 of the switch assemblies 40,50 before any portion of the depressing force can be transferred to the other components of the switch assemblies 40,50, as will be discussed in further detail below. Third, the switch assemblies 40,50 are located on the same housing 22 of the light 20 that includes the grip portion 23, thereby automatically placing the user's forward-located hand in the vicinity of the switch assemblies 40,50 and ensuring that the user will not have difficulty locating either or both of the switch assemblies 40,50.

FIGS. 3 and 4 show the light 20 in its fully-assembled state. In this embodiment, the light 20 comprises a housing 22 that includes two housing halves 24,28, the grip portion 23, a firearm-attachment portion 34 that is used to removably attach the light 20 to a portion of a firearm (e.g., magazine tube 16 of shotgun 2), the light assembly 38, and the switch assemblies 40,50. In this embodiment, housing half 24 includes a fastener passage 25 and housing half 28 includes fastener passages 29,30,31 through which appropriate fasteners (e.g., machine screws; not shown) may be passed so that the housing halves 24,28 are fixedly joined together.

The light assembly 38 comprises a lamp (not shown; for example one or more LEDs), a reflector (not shown), and a lens 39, as would be understood by one having ordinary skill in the art. The housing 22 further comprises a battery compartment (not labeled) in which one or more power sources (e.g., removable or rechargeable batteries) that power the light 20 are held. In this embodiment, the battery compartment is concealed by a cover 36, which in this embodiment includes a slot 37. In this embodiment, the slot 37 is indented within the cover 36 and sized and shaped such that a coin or flathead screwdriver can be inserted within the slot 37 and used to loosen from or tighten the cover 36 onto the battery compartment.

In the present embodiment, the firearm-attachment portion 34 of the light 20 is sized and shaped to fit a particular make and model of shotgun, specifically the Mossberg 500 and similar models. It should be understood that the light 20 according to the present disclosure could be modified to fit any type of firearm, for example different types of shotguns, rifles, other long arms, pistols, revolvers, or other sidearms, with the necessary size and shape changes having been made to the firearm-attachment portion 34 thereof to either custom fit a particular firearm mounting portion (e.g., a magazine tube, barrel, or other firearm component) or being equipped with adjustable fasteners, clips, spring-loaded clamps, or other means that allow the light 20 to be snugly attached to a range of firearms within a particular class or classes of firearm.

Turning back to the present embodiment, the housing half 24 of the housing 22 includes a switch recess 26 into which the switch assembly 40 is installed, and the housing half 28 of the housing 22 includes a switch recess 32 into which the switch assembly 50 is installed. In this embodiment, each of the switch assemblies 40,50 is installed within its respective switch recess 26,32 so that the outer portions of each switch assembly 40,50 (i.e., weld plates 41,52 and boots 42,54) are flush with the outer surface of the respective housing half 24,28, and the exterior sides of the boots 42,54 of the respective switch assemblies 40,50 each include a curved surface that conforms to the shape of the respective housing half 24,28. As would be understood by a person having ordinary skill in the art, the switch assemblies 40,50 are wired to the battery compartment as a power source and to the light assembly 38 so that the light assembly 38 can be turned on and off and/or otherwise adjusted (e.g., light intensity, light mode) via the switch assemblies 40,50. The arrangement and functionality of the contents of the housing 22 are otherwise standard in the art, and will not be described further herein.

FIGS. 5-8 show various components of the switch assembly 50, it being understood that switch assembly 40 is identical thereto and that all of the discussion herein specific to switch assembly 50 is equally applicable to switch assembly 40. FIG. 5 shows the switch assembly 50 fully exploded and located aligned above the switch recess 32 of the housing half 28 of the housing 22. FIG. 5 shows a weld rim 33 located within the switch recess 32. When the switch assembly 50 is fully assembled, a weld plate 52 of the switch assembly 50 secures a boot 54 thereof and the weld plate 52 is welded down to the weld rim 33 within the switch recess 32, to fully install the switch assembly 50 to the housing 22 of the light 20. A weld plate 41 of the switch assembly 40 secures a boot 42 thereof and the weld plate 41 is welded down to a corresponding weld rim (not shown) located within the switch recess 26, to fully install the switch assembly 40 to the housing 22 of the light 20.

In this embodiment, the weld plates 41,52 are welded to the respective switch recess 26,32 via ultrasonic welding. In alternate embodiments, it should be understood that any other suitable type of welding technique, an adhesive, one or more fasteners, or a pressure/snap-fit/tab-and-slot design could be used to secure one or both of the switch assemblies 40,50 to the respective switch recess 26,32 via an outer plate (e.g., weld plates).

Referring back to the Figures, in this embodiment the weld plate 52 includes an interior area 53 (i.e., corresponding with its interior perimeter) into which the boot 54 fits. The boot 54 comprises a depressible portion 55 that is visible and accessible within the interior area 53 and a rim portion 56 that is concealed underneath the rim of the weld plate 52 when the switch assembly 50 is fully assembled. The boot 54 further comprises an exterior side 58 that may be contacted by a user's hand when the user wants to actuate the switch assembly 50, and an interior side 59 including an opening 61. In this embodiment, the boot 54 is comprised of a rubber material. In alternate embodiments, the boot 54 could be comprised of any suitable depressible or deformable material.

In the present embodiment, the switch assembly 50 further comprises: a bar 70 having a top surface 71, a bottom surface 72, and three holes 74a,74b,74 routed therethrough; actuating buttons 76a,76b,76c, each of which has a respective portion 78a,78b,78c associated with its upper side and a respective portion 80a,80b,80c associated with its lower side; a strip of adhesive tape 82; tactile switches 86a,86b,86c; and a printed circuit board (PCB) 92 having contacts 94a,94b,94c. The PCB 92 is fitted within the switch recess 32 and the contacts 94a,94b,94c are electrically connected to the contacts/PCB of the switch assembly 40, the battery compartment (i.e., the power source), and the light assembly 38 of the light 20 through known methods and arrangements.

When the switch assembly 50 is fully assembled, the bar 70 is fitted within the opening 61 in the boot 54 (see FIG. 7) and snugly held in place by corner ribs 64a,64b,64c,64d located at the four corners of the interior side 59 of the boot 54 that are sized and shaped to partially undercut (i.e., sit atop the bottom surface 72 of) the bar 70. In the present embodiment, the actuating buttons 76a,76b,76c are each installed partially within a respective hole 74a,74b,74c in the bar 70. Specifically, portion 78a of the actuating button 76a is press fit into and extends through the hole 74a in the bar 70 while portion 80a thereof rests against the bottom surface 72 of the bar 70, portion 78b of the actuating button 76b is press fit into and extends through the hole 74b in the bar 70 while portion 80b thereof rests against the bottom surface 72 of the bar 70, and portion 78c of the actuating button 76c is press fit into and extends through the hole 74c in the bar 70 while portion 80c thereof rests against the bottom surface 72 of the bar 70. In this embodiment, each of the portions 78a,78b,78c of the respective actuating button 76a,76b,76c extends partially beyond the top surface 71 of the bar 70 and sits within a respective cutout 62a,62b,62c located in a protruding rib 60 that extends from the interior side 59 of the boot 54. The protruding rib 60 functions to direct the depressing force that is applied to the boot 54 by the user toward an axial centerline of the bar 70 (as measured along its length 73), which in turn focuses said force to the actuating buttons 76a,76b,76c and consequently directly to the switches 86a,86b,86c. This arrangement increases the responsiveness and reliability of the switch assembly 50. The interior side 59 of the boot 54 further comprises ribs 66a,66b,66c,66d extending outwardly therefrom, which act to space the boot 54, bar 70, and actuating buttons 76a,76b,76c away from the PCB 92.

In this embodiment, each of the switches 86a,86b,86c is of dome-type (e.g., having an at least partially-convex curved shape) and has a respective body 88a,88b,88c and a respective dimple 90a,90b,90c that protrudes outwardly from the respective body 88a,88b,88c (i.e., towards the respective portion 80a,80b,80c of the respective actuating button 76a,76b,76c when the switch assembly 50 is fully assembled). Switch 86a is aligned above and secured to contact 94a located on the PCB 92 via the strip of adhesive tape 82, switch 86b is aligned above and secured to contact 94b located on the PCB 92 via the strip of adhesive tape 82, and switch 86c is aligned above and secured to contact 94c located on the PCB 92 via the strip of adhesive tape 82. In this embodiment, the strip of adhesive tape 82 contains three holes 84a,84b,84c, each of which aligns with a respective dimple 90a,90b,90c of a respective switch 86a,86b,86c when the switch assembly 50 is fully assembled, so that the dimples 90a,90b,90c are not covered by the strip of adhesive tape 82 and the strip of adhesive tape 82 does not interfere with functioning of the dimples 90a,90b,90c. The strip of adhesive tape 82 acts to hold each of the switches 86a,86b,86c in place on a respective contact 94a,94b,94c of the PCB 92. Although, in the present embodiment, a single strip of adhesive tape 82 is used to hold all three switches 86a,86b,86c in place on the PCB 92, in alternate embodiments separate pieces of adhesive tape could be used instead, and/or the holes 84a,84b,84c for the dimples 90a,90b,90c of the switches 86a,86b,86c could be omitted entirely.

Turning back to the present embodiment, the switches 86a,86b,86c are spaced apart on the PCB 92, with approximately 1.50 inches (3.81 cm) between each switch and approximately 0.50 inches (1.27 cm) of space left on either side of the end switches 86a,86c, so that the switch assembly 50 of the present embodiment has a length 51—as measured between the edges of the boot 54—of approximately 4.00 inches (10.16 cm). This extended switch length allows for the user to easily locate and actuate the switch assembly 50 without looking therefor, which is especially helpful in low-light or other vision-impaired environments in which the switch assembly 50 may be difficult to see or where the quickest possible reaction time is desirable. In alternate embodiments, additional switches of even greater extended length are possible in view of the present disclosure, and if necessary to ensure proper functionality could employ multiple depressible boots/bars along their length.

The switches 86a,86b,86c in the present embodiment are TC series tactile dome switches made by Snaptron Inc. of Windsor, Colo., U.S.A. In this embodiment, each of the switches 86a,86b,86 has a reverse (i.e., protruding) dimple 90a,90b,90c on the top of the respective body 88a,88b,88c that serves as a built-in actuator, and each switch 86a,86b,86c has a trip (i.e., actuation) force of 340 g. In other words, each of the switches 86a,86b,86c will trip such that its respective body 88a,88b,88c will deform and come into contact with a respective contact 94a,94b,94c on the PCB 92 when subjected to a minimum of 340 g of a respective applied force that is applied by each of the actuating buttons 76a,76b,76c to the respective switch 86a,86b,86c. In the present embodiment, when any one of the contacts 94a,94b,94c is contacted by a respective switch 86a,86b,86c (i.e., any of the switches 86a,86b,86c is moved, the light assembly 38 of the light 20 is activated. In one respect, each applied force could be measured along a force vector parallel to depression directions 96a,96b. In another respect, each applied force could be measured according to a recognized test standard for tactile switches, for example ASTM Test Method No. 2592, entitled Standard Test Method for Measuring the Force-Displacement of a Membrane Switch, the entire contents of which are incorporated herein by reference.

In alternate embodiments, two tactile switches or more than three tactile switches can be used in the switch assembly 50, with the bar 70 or other pressing mechanism appropriately located atop and spanning across the switches such that the application of a suitable amount of a depressing force anywhere along the length 51 of the switch assembly 50 causes the bar 70 to transfer an amount of force to at least one of the switches sufficient to actuate the light assembly 38, either with or without the use of intermediate actuating buttons used to focus the depressing force to the switches. In alternate embodiments, the switches could be altered or selected to trip at any particular quantity of trip force, and individual tactile switches used within a single switch assembly 50 need not have identical trip force ratings. For example, one or more switches located closer to the center of the length 51 of the switch assembly 50 could have a higher trip force rating than one or more switches placed near the ends of the length 51 of the switch assembly 50, to reflect that it may generally be easier for a user to impart higher forces along the center portion of the length 51 of the switch assembly 50 as compared to the ends thereof. In further alternate embodiments, the switches could be of any pressure-sensitive type, for example any type of known or hereafter-developed mechanical switch, pressure pad, pressure plate, or other pressure-sensitive type of switch capable of being changed between a first state and a second state or capable of sending an appropriate signal when an applied force of threshold value has been received.

Activation of the light assembly 38 involves changing at least one state thereof, including but not limited to an on/off state, light mode (e.g., solid, flashing, strobing), light intensity (e.g., low, medium, high), light color, and/or light beam shape (e.g., spot/flood). Different combination of switch assembly taps or timed depressions could be used in various embodiments according to the present disclosure to alter the various states of the light assembly 38.

In the present embodiment, the switch assemblies 40,50 are redundant in that they are both designed to change the on/off state of the light assembly 38 of the light 20, for ease of either right-hand-forward or left-hand-forward use. In alternate embodiments, the switch assemblies 40,50 could be designed to perform different functions with respect to states of the light assembly 38, e.g., with respect to changes to mode, intensity, color, and/or light beam shape, as would be appreciated by a person having ordinary skill in the art.

It is also desirable to provide a forend for a firearm that has improved handling and safety feature(s) over the known prior art. While such a forend may include a light and/or one or more switch assemblies according to the present disclosure, it need not. Said another way, a forend having the basic structure as discussed below, but omitting a light and/or one or more switch assemblies, is envisioned for alternative embodiments according to the present disclosure. Moreover, a firearm (e.g., a long gun such as a rifle or shotgun) comprising a forend having the increased handling and safety feature(s) discussed herein below is further appreciated by the inventors.

Referring now to FIGS. 13-15, another embodiment of a firearm-mountable light 120 according to the present disclosure will be described in detail. FIG. 13 shows portions of an exemplary long gun in phantom lines, in the form of a shotgun that includes a barrel 12′ and a magazine tube 16′ onto which the firearm-mountable light 120 is installed as a replacement for a stock forend, as would be appreciated by a person having ordinary skill in the relevant art.

FIGS. 14 and 15 show left and right side views, respectively, of the light 120 according to the present disclosure, in an unmounted configuration. Except as explained below in detail, all portions, parts, and assemblies of the light 120 of the present embodiment should be understood to be structurally and functionally identical or substantially equivalent to the respective portions and assemblies of the embodiment of the light 20 shown in FIGS. 1-12 and described above, and the light 120 of the present embodiment should be understood to include all of the same portions, parts, and assemblies as the light 20 shown in FIGS. 1-12 and described above, unless explicitly stated otherwise below.

In the embodiment of FIGS. 13-15, the light 120 includes a housing 122 comprising a grip portion 132 and a light assembly 138, with a finger slot 160 located between the grip portion 132 and the light assembly 138 into which a user can insert all or a portion of one or more fingers while gripping at least a portion of the grip portion 132 of the housing 122 with all or a portion of the remainder of their forward-positioned hand. In this embodiment, the light 120 further comprises a strap 178 that is attached to the housing 122 via brackets 170,174, which are each attached to the housing 122 via a respective fastener 172,176 that is routed through the body of the housing 122. The strap 178 extends at least partially below each of the grip portion 132 and the finger slot 160. In the present embodiment the strap 178 is made of a flexible material and its brackets 170,174 are pivotably attached to the housing 122 via the fasteners 172,176. In alternative embodiments, the strap 178 may be made of a rigid or inflexible material and/or one or both of the brackets 170,174 may be non-pivotable with respect to the housing 122. In further alternative embodiments, the strap 178 may be replaced by an extension piece that is integral with the housing 122 and that extends at least partially below each of the grip portion 132 and the finger slot 160, or the strap 178 may be omitted entirely.

Turning back to the embodiment of FIGS. 13-15, both the strap 178 and the finger slot 160—as further discussed below—minimize the risk that the user's hand will come free of the light 120 when it is used (e.g., when being fired or used during slippery conditions). The light 120 also includes a pair of switch assemblies 140,150 located on opposite sides of the housing 122, each of which is operably connected to the light assembly 138. The switch assemblies 140,150 and light assembly 138 are structurally and functionally identical to the switch assemblies 40,50 and light assembly 38, respectively, of the embodiment of the light 20 shown in FIGS. 1-12 and described above.

In the embodiment of FIGS. 13-15, the housing 122 comprises a front surface 124 (corresponding with the location of the light assembly 138) and a rear surface 128 (corresponding with the opposite end of the housing 122). In this embodiment, the front surface 124 of the housing 122 is relatively flat and its forward-most (i.e., front-most) edge—when viewed orthographically (i.e., straight-on) from its side, as shown in FIGS. 14 and 15, and excluding its lens assembly (not labeled)—lies in a plane 126 that is oriented perpendicularly to a line 131 drawn horizontally through the housing 122 when viewed orthographically (i.e., straight on) from its side. Further, in this embodiment, the rear surface 128 of the housing 122 is relatively flat and its rearward-most (i.e., back-most) edge—when viewed orthographically from its side, as shown in FIGS. 14 and 15—lies in a plane 130 that is also oriented perpendicularly to the line 131.

In this embodiment, a forward-located portion of the finger slot 160 comprises a surface 162 that terminates in a point 166 at its lowermost edge. The surface 162 has a concave-like or arcuate shape such that at least some portions of the surface 162 terminate forwardly of the point 166 when the light 120 is viewed orthographically from its sides, as in FIGS. 14 and 15. Said another way, the surface 162 and point 166 collectively form a “hook”-like shape comprising a depression into which portions of one or more of the user's fingers can be placed when the light 120 is being held. The point 166 is located below the surface 162 such that the user's one or more fingers can be placed in contact with the surface 162 above the point 166 (as viewed straight-on from a side in an upright orientation of the light 120, as shown in FIGS. 14-15). Said yet another way: a plane 164 that is oriented perpendicularly to line 131 through the forward-most point of the surface 162 of the finger slot 160 is located a first distance d₁ from the plane 126 (measured perpendicularly between the planes 126,164); a plane 168 that is oriented perpendicularly to line 131 through the point 166 is located a second distance d₂ from the plane 126 (measured perpendicularly between the planes 126,168); and the first distance d₁ has a lower value than the second distance d₂. The “hook-shape” of the finger slot 160—i.e., containing a forward-located “depression” or indentation located above a rearward-extending point or edge—acts to prevent the user's hand from coming loose from the light 120 during operation of a firearm to which it is attached, by resisting downward movement of the one or more fingers out of the finger slot 160.

Although exemplary implementations of the herein described systems and methods have been described in detail above, those skilled in the art will readily appreciate that many additional modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of the herein described systems and methods. Accordingly, these and all such modifications are intended to be included within the scope of the herein described systems and methods. The herein described systems and methods may be better defined by the following exemplary claims.
