CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application No. 62/100,145, filed on Jan. 6, 2015. The entire disclosure of the above application is incorporated herein by reference. 
    
    
     FIELD 
     The present technology relates to a system for a firearm configured to provide a status of an ammunition level, such as the ammunition level remaining in a magazine for a semi-automatic or automatic firearm, where an operator can maintain focus on an aiming device while receiving the status of the ammunition level. 
     INTRODUCTION 
     This section provides background information related to the present disclosure which is not necessarily prior art. 
     When firing a semi-automatic or automatic firearm in various applications, including law enforcement, military, and competitive shooting applications, it can be desirable to know when an ammunition reservoir, such as a firearm magazine, is about to run out of ammunition. Competitive shooters can use this information so they can be prepared to release an empty or partially empty magazine and replace it with a full one with a minimum loss of shooting time in a course of fire. In police and military applications, the need to know ammunition status can be far more serious. Police officers and soldiers can jeopardize their lives in the split second it takes to realize a magazine must be replaced, or an enemy combatant or suspect can escape in that time. For example, under the stress of deploying a firearm or during a firefight, it can be nearly impossible for a firearm operator to keep accurate track of the amount of spent ammunition and the amount of remaining ammunition. 
     Ammunition level in a firearm can be checked in various ways. The firearm operator can remove a magazine to determine if ammunition remains therein. Also, various magazines can be manufactured with various windows or apertures that allow the number of cartridges and/or cartridge position therein to be viewed. For example, numbered or indexed windows or apertures can show the number of cartridges contained within the magazine or provide a quick view as to the approximate portion of the magazine that still holds ammunition or that is empty. Other types of ammunition counters can be employed, including those that provide a numeric counter or display relating to the ammunition level of the firearm. However, a considerable drawback of these ways of checking the ammunition level is that the operator must remove and/or physically inspect the magazine or the operator must divert his or her vision or attention to the counter or display. Diverting one&#39;s attention or the act of removing a magazine to check ammunition level can break the firearm operator&#39;s focus from the task at hand and can disrupt the operator from concentrating on one or more targets. This can seriously impact the effectiveness of the operator in certain scenarios, including law enforcement, military, and competitive shooting applications. 
     It would be desirable to provide a system capable of indicating the ammunition status of a firearm where the firearm operator would not have to divert attention away from an aiming device of the firearm.

     DETAILED DESCRIPTION 
     The following description of technology is merely exemplary in nature of the subject matter, manufacture and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as may be filed claiming priority to this application, or patents issuing therefrom. Regarding the methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word “about” and all geometric descriptors are to be understood as modified by the word “substantially” in describing the broadest scope of the technology. 
     Although the open-ended term “comprising,” as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more limiting terms such as “consisting of” or “consisting essentially of” Thus, for any given embodiment reciting a system, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such systems, components, or process steps excluding additional systems, components, or processes (for consisting of) and excluding additional systems, components, or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional systems, components, or processes are not explicitly recited in this application. For example, recitation of a system, component, or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein. 
     The present technology relates to systems, methods, and articles of manufacture that provide for reporting an ammunition status of a firearm to an operator of the firearm, where the firearm includes at least one aiming device. A status means is included for determining the ammunition status of the firearm and a reporting means is included for reporting the ammunition status of the firearm. The reporting means receives the ammunition status of the firearm from the status means and reports the ammunition status of the firearm within a field of view of the operator when the operator is using the aiming device of the firearm. In this way, the firearm operator does not have to divert his or her attention away from the aiming device. The operator can therefore continue to maintain focus on a target and/or continue to aim and discharge the firearm at one or more targets while being informed as to the ammunition status of the firearm. There is accordingly no need for the operator to break concentration on observable targets in conjunction with the aiming device in order to check ammunition status. 
     A system according to the present technology can include a status means and a reporting means. The status means can determine the ammunition status of the firearm. The reporting means can report the ammunition status of the firearm by receiving the ammunition status of the firearm from the status means. The reporting means can report the ammunition status of the firearm within a field of view of the operator when the operator is using the aiming device of the firearm. 
     The status means can include a translation means and a signaling means. The translation means can be configured to change a position relative to the ammunition status of the firearm. The signaling means can be configured to ascertain the position of the translation means and communicate the ammunition status of the firearm to the reporting means. The translation means can be coupled to a magazine follower, the magazine follower comprising part of a magazine configured to hold ammunition for the firearm. The translation means can be coupled to a magazine spring, the magazine spring comprising part of a magazine configured to hold ammunition for the firearm. The signaling means can be configured to be coupled to a portion of the firearm that receives a portion of a magazine configured to hold ammunition for the firearm. The signaling means can be configured to engage a portion of the firearm involved in assembly of the firearm. For example, the signaling means can be configured to engage a portion of a retaining pin of the firearm, requiring manipulation of the retaining pin to in order to couple or uncouple the signaling means to the firearm. The retaining pin can couple an upper assembly of the firearm with a lower assembly of the firearm. In this way, removal or manipulation of the retaining pin can be required to couple or uncouple the signaling means to the firearm. This can prevent unintentional decoupling of the signaling means from the firearm. 
     The translation means can include one or more magnets and the signaling means can be configured to detect the proximity of the one or more magnets. The signaling means can include one of a reed switch and a Hall effect sensor to detect the proximity of the one or more magnets. For example, as the translation means changes a position relative the ammunition status in a magazine, the signaling means can sense the position of the one or more magnets and provide a signal correlated to the ammunition status of the firearm. The translation means and the signaling means can also employ other detection methods to detect proximity and/or distance to each other. For example, one of the translation means and the signaling means can use radio-frequency identification (RFID), such as an RFID chip and the other of the translation means and the signaling means can include an RFID detector or reader. The translation means can use a passive RFID transponder that is independent of an energy source such as a battery or the like. Another example includes where the translation means is an RFID chip coupled to or embedded within a magazine follower and the signaling means is coupled to or embedded within a portion of the firearm that receives a portion of a magazine configured to hold ammunition for the firearm, such as magazine well. 
     The status means can provide the ammunition status of the firearm to the reporting means in various ways. The status means can be directly connected to the reporting means, where the reporting means can receive the ammunition status of the firearm by an electric signal through a wire or other physical connection, for example. The status means can also be configured to wirelessly transmit the ammunition status of the firearm and the reporting means can be configured to wirelessly receive the ammunition status of the firearm from the status means. For example, the status means and the reporting means can communicate using a wireless technology standard such as Bluetooth™. In this way, there does not have to be a physical connection between the status means and the reporting means. This can allow the apparatus to be configured for various firearm architectures and allow variable distances between the status means and the reporting means. The firearm can also be configured to facilitate communication of the ammunition status of the firearm between the status means and the reporting means. For example, coupling or mounting of the status means on the firearm can include coupling to an interface integral with the firearm that communicates with another interface integral with the firearm for coupling or mounting the reporting means. 
     The reporting means can be configured in various ways. The reporting means can be coupled to the aiming device of the firearm. In this manner, the reporting means can be used in conjunction with an existing aiming device or can be used to retrofit an existing aiming device. The reporting means can also comprise a portion of the aiming device or can comprise the entirety of the aiming device. Where the reporting means forms at least a portion of the aiming device, the reporting means can be integrated with the aiming device. An integrated reporting means and aiming device can form the only aiming device on the firearm or the firearm can include one or more additional aiming devices. The reporting means can be configured to work with or form part of various firearm aiming devices, including front and rear sights, including backup iron sights, a telescopic sight, a holographic sight, a reflex sight, a red dot sight, an infrared sight, a night vision sight, and a thermal sight. The aiming device can be releasably coupled to the firearm or the aiming device can be integral to the firearm, where it is formed as part of the firearm, for example. The aiming device can include one or more aiming points of reference, such as one or more dots, reticles, hashmarks, ticks, or crosshairs. Such aiming points of reference can be scaled in various ways, including mils or mil dots or minutes-of-angle. For example, the reporting means can be coupled to or be part of a telescopic sight on a firearm, where the firearm further includes backup iron sights. The reporting means can also be configured to report the ammunition status of the firearm within a field of view of the operator when the operator is using more than one aiming device of the firearm. For example, the reporting means can be part of a red dot sight that co-witnesses with front and rear sights. Alternatively, the reporting means can provide independent reporting of the ammunition status of the firearm within a field of view of the operator when the operator is using different aiming devices of the firearm. Another example includes where the reporting device provides a color change of an aiming point of reference of the aiming device when a certain ammunition status of the firearm occurs, such as when a predetermined number of trigger pulls remain in a semi-automatic firearm or when a predetermined number of defined bursts remain in a selective fire firearm. 
     The ammunition status of the firearm can be reported by the reporting means in various ways. These can include one or more various visual signals provided within a field of view of the operator when the operator is using the aiming device of the firearm. The ammunition status can include a representation of when a predetermined amount of ammunition remains (e.g., five rounds remain), a representation of how much ammunition remains (e.g., a numerical round count of actual rounds remaining), or step-wise representation of the amount of ammunition remaining (e.g., a visual signal indicating a full magazine, another visual signal for a half magazine, and yet another visual signal for a nearly empty magazine). The ammunition status of the firearm can be reported in various ways, including a numerical value, a color change, an intensity change, a pulsing, a flashing, a shape change, and combinations thereof. For example, all or a portion of a reticle of a holographic sight can change color, change intensity, pulse, flash, and/or change shape when one or more certain conditions relating to ammunition status of the firearm are met. As another example, the reporting means can be configured as a reticle, dot, or post of the aiming device and can change color from green to yellow to red as ammunition depletion thresholds are achieved. As yet another example, the reporting means can be configured to pulse or flash a portion of the reticle of the aiming device when the ammunition status of the firearm drops to a predetermined value. 
     The status means and/or the reporting means can be configured to wirelessly transmit the ammunition status of the firearm to a remote entity. In this way, the system can communicate the ammunition status of the firearm to various personnel as well as various automated reporting systems. Examples of various remote entities include other operators, a command unit, headquarters, a supply system, a maintenance system, and a scoring system. The remote entity can therefore be apprised of the ammunition status of the firearm and hence the ammunition expended by the operator. Other firearm operators and/or a commander can thereby determine whether a given operator has expended or is expending ammunition and whether the operator requires support or resupply of ammunition. A supply system remote entity can be automated to order and/or dispatch ammunition to an operator based on the ammunition status of the firearm. Where the firearm is supplied ammunition via a belt-feed, for example, the supply system can dispatch one or more large containers of ammunition associated with such firearms. Likewise, a maintenance system can track the ammunition status of the firearm to determine how many rounds have been discharged for a given firearm and schedule certain maintenance services for the firearm, such as replacement of one or more parts, cleaning, lubrication, etc. Such automated preventative maintenance can improve the performance of the firearm. For competitive shooters, a remote system can track ammunition status of the firearm where expended ammunition can be included as part of a scoring system for a competitive course of fire. 
     The status means and/or the reporting means can also be configured to wirelessly transmit a location and/or a direction of the system to the remote entity. The status means and/or the reporting means can include a global position system (GPS) and/or an electronic compass to determine location of the system and the direction the reporting means and hence aiming device is facing. In this way, location and direction of ammunition expenditure can be determined by the remote entity. 
     Methods are provided for reporting an ammunition status of a firearm to an operator, where the firearm includes an aiming device. Methods can include determining the ammunition status of the firearm and reporting the ammunition status of the firearm within a field of view of the operator when the operator is using the aiming device of the firearm. The methods can employ the various systems, elements, and features described herein. The methods can further include transmitting the ammunition status of the firearm to a remote entity. The methods can also include transmitting a location and/or a direction of the system to the remote entity. 
     EXAMPLES 
     With reference now to the figures, example embodiments of the present technology are shown. 
     A system  100  is shown for reporting an ammunition status of a firearm  105  to an operator  110 , where the firearm includes a holographic sight  115  as a first aiming device and a front iron sight  120  as a second aiming device. The system  100  includes a status means configured as a status element  125  that determines the ammunition status of the firearm  105 . The system  100  also includes a reporting means configured as a first reporting element  130  and a second reporting element  135 , each configured for reporting the ammunition status of the firearm  105 . As shown, the first reporting element  130  is integrated as part of the holographic sight  115  as the first aiming device and the second reporting element  135  is integrated as part of the front iron sight  120  as the second aiming device. It is understood that the system  100  may include only the holographic sight  115  and integrated first reporting element  130  or include only the front iron sight  120  and integrated second reporting element  135 , depending on the type and desired configuration of aiming device(s) on the firearm  105 . The first reporting element  130  and the second reporting element  135  each receive the ammunition status of the firearm  105  from the status element  125 , where the first reporting element  130  and the second reporting element  135  each report the ammunition status of the firearm within a field of view of the operator  110  when the operator  110  is using the holographic sight  115  as the first aiming device and/or the front iron sight  120  as the second aiming device. 
     The status element  125  includes a translation element  140  configured to change a position relative to the ammunition status of the firearm  105  and a signaling element  145  configured to ascertain the position of the translation element  140  and communicate the ammunition status of the firearm  105  to the first reporting element  130  and the second reporting element  135 . As shown in  FIGS. 5A-5B  and  FIGS. 6A-6B , the translation element  140  is coupled to a magazine follower  150 , where the magazine follower  150  is part of a magazine assembly  155  configured to hold ammunition for the firearm  105 . As shown in the exploded view of  FIGS. 5A-5B , the magazine assembly  155  is configured as a detachable box magazine having a magazine box  160  into which the magazine follower  150 , including the translation element  140 , and a magazine spring  165  are inserted and contained by a base plate  170 . It is understood that other types of magazine assemblies  155  can be employed, including integral box magazines, tubular magazines, rotary magazines, horizontal magazines, casket magazines, rotary magazines, pan magazines, and drum magazines. Another embodiment the translation element  140  is shown in  FIG. 7 , where the translation element  140  is coupled to the magazine spring  165  near the magazine follower  150 , the magazine spring  165  comprising part of the detachable box magazine configured to hold ammunition for the firearm  105 . In this way, the translation element  140  is separate from the magazine follower  150 . 
     The translation element  140  includes a body  175  that receives a magnet  180 . In the embodiment shown in  FIGS. 5A-5B  and  FIGS. 6A-6B , the body  175  can be coupled to the magazine follower  150  by snapping into an underside  185  of the magazine follower  150  so as not to interfere with loading of the magazine assembly  155 . It should be understood that the body  175  of the translation element  140  can also be formed as an integral portion of the magazine follower  150 . Likewise, the magazine follower  150  and body  175  of the translation element  140  can be formed around the magnet  180  using various methods; e.g., injection molding. Integrating the body  175  and magnet  180  with the magazine follower  150  can simplify construction and make the integrated product resistant to disassembly. As shown in the embodiment depicted in  FIG. 7 , the body  175  of the translation element  140  can also be coupled to the magazine spring  165  near the magazine follower  150  so that the translation element  140  is separate from the magazine follower  150 . 
     The magnet  180  received in the body  175  of the translation element  140  changes position relative to the ammunition status of the firearm  105 . With respect to the embodiment of the magazine assembly  155  shown as a detachable box magazine, the magazine spring  165  is compressed inside the magazine box  160  relative to the amount of ammunition pressing against the magazine follower  150 . As ammunition is loaded into the magazine assembly  155  or expended or removed from the magazine assembly  155 , the magazine spring  165  compresses or expands respectively against the magazine follower  150 , along with the translation element  140 . For example, as ammunition is expended, the magnet  180  moves from a lower portion  190  of the magazine assembly  155  to an upper portion  195  of the magazine assembly  155 . 
     As noted, the signaling element  145  is configured to ascertain the position of the translation element  140  and communicate the ammunition status of the firearm  105  to at least one of the first reporting element  130  and the second reporting element  135 . The signaling element  145  is shown in  FIGS. 1, 4A-4B, and 4E-4F , as coupled directly to a magazine well  200  of the firearm  105 . The magazine well  200  is a portion of the firearm  105  that receives a portion of the magazine assembly  155 , such as the detachable box magazine depicted. However, it is understood that the signaling element  145  may be coupled to the magazine assembly  155  or to other portions of the firearm  105 . The embodiment of the signaling element  145  shown includes a retaining tab  205  that is configured to engage a portion of a retaining pin  210  of the firearm  105 , requiring manipulation of the retaining pin  210  in order to couple or uncouple the signaling element  145  to the firearm  105 . In this way, the retaining tab  205  is held behind the retaining pin  210  and the signaling element  145  is effectively fixed to the firearm  105  and cannot be removed without sliding the retaining pin  210  out past the retaining tab  205 . The signaling element  145  is therefore secured to the firearm  105  through impact or shock. It is understood that the signaling element  145  can be configured to require partial or complete removal of the retaining pin  210  for installation or removal from the firearm  105  and/or partial or complete disassembly of the firearm  105  may be necessary for installation or removal of the signaling element from the firearm  105 . The embodiment of the signaling element  145  shown further includes resilient tabs  215  that snap onto either side of the magazine well  200  of the firearm  105  to further secure the signaling element  145  to the firearm  105  and provide a flush fit with the magazine well  200 . A gripping surface  220  can be provided on an outer surface of the signaling element  145 , where the gripping surface can include a texture and/or material (e.g., rubber) that enhances gripping by the operator  110 . It is understood that the gripping surface  220  can be larger than shown in the figures and can include one or more finger grooves (not shown) to further aid the operator  110  in securely gripping the firearm  105 . 
     The embodiment of the signaling element  145  shown is configured to detect the proximity of the magnet  180  of the translation element  140 . In particular, the signaling element  145  includes one of a reed switch and a Hall effect sensor that can sense the proximity of the magnet  180  and can provide a change in a signal in relation to proximity of the magnet  180  and hence the strength of the related magnetic field. The proximity of the magnet  180  is converted by the signaling element  145  to a signal indicative of the ammunition status of the firearm  105 , where the signal is communicated to the respective reporting element  130 ,  135 . 
     In the embodiments shown, the first reporting element  130  and the second reporting element  135  are each configured to receive the signal indicative of the ammunition status of the firearm  105  from the status element  125 , which includes the translation element  140  and the signaling element  145 . The signaling element  145  is configured to wirelessly transmit the ammunition status of the firearm  105  and the respective reporting elements  130 ,  135  are configured to wirelessly receive the ammunition status of the firearm  105  from the signaling element  145 . It should be understood that the signaling element  145  can also be hard wired to the respective reporting elements  130 ,  135 . In this way, the translation element  140  including the magnet  180  presents a position relative to the ammunition status of the firearm, where the reed switch or Hall effect sensor of the signaling element  145  ascertains the position of the translation element  140  and associated magnet or a change in position of the translation element  140  and associated magnet  180 . The signaling element  145  then wirelessly communicates a signal indicative of the ammunition status of the firearm  105  to the respective reporting element  130 ,  135 . 
     With reference to  FIGS. 2A-2B and 3A-3B , the first reporting element  130  and the second reporting element  135  form a portion of the holographic sight  115  and the front iron sight  120 , respectively. With respect to the holographic sight  115 , the first reporting element  130  changes color to indicate a predetermined ammunition status of the firearm  105 ; compare the color of the first reporting element  130  in  FIG. 3A  versus  FIG. 3B . Likewise, the second reporting element  135  of the front iron sight  120  changes color to indicate a predetermined ammunition status of the firearm  105 ; compare the color of the second reporting element  135  in  FIG. 2A  versus  FIG. 2B . The predetermined ammunition status of the firearm  105  can be where the magazine assembly  155  has only five rounds of ammunition remaining, for example. 
     An alternate embodiment of a reporting element  225  that can be coupled to an aiming device  230  of a firearm  105  is shown in  FIGS. 9A-9B . Here, the reporting element  225  is not integrated into the aiming device  230 . As depicted, the reporting element  225  is configured as ring that slides onto an optical sight used as the aiming device  230 . An existing aiming device  230  can be outfitted or retrofitted with the reporting element  225  of the present system  100  in this manner. All or a portion of the ring edge  235  facing the operator  110  can accordingly report the ammunition status of the firearm  105  within a field of view of the operator  110  when the operator  110  is using the aiming device of the firearm  105 . For example, the ring edge  235  can change color, in a similar fashion to the first reporting element  130  in  FIG. 3A  versus  FIG. 3B  and the second reporting element  135  in  FIG. 2A  versus  FIG. 2B . Alternatively, the reporting element  225  coupled to the aiming device  230  can communicate with the aiming device  230  to cause an indication of the ammunition status of the firearm  105  using a feature of the aiming device  230 , such as color change, pulsing, or flashing in the reticle or red dot of the aiming device  230 . 
     The system  100  for reporting an ammunition status of a firearm  105  to an operator  110  can also wirelessly communicate the ammunition status of the firearm  105  to a remote entity  240 , as shown in  FIG. 8 . Likewise, multiple systems  100  can each be configured to transmit the ammunition status of the respective firearm  105  to the remote entity  240 . The remote entity  240  can be another operator  110 , a command unit or headquarters, a supply system, a maintenance system, or combinations of these entities. For example, where the status element  125  includes the signaling element  145 , the signaling element can wirelessly communicate the ammunition status of the firearm  105  to the first reporting element  130  and/or the second reporting element  135  as well as the remote entity  240 . Alternatively, the first reporting element  130  and/or the second reporting element  135  can relay the ammunition status of the firearm  105  received by the signaling element to the remote entity  240 . The remote entity  240  can therefore ascertain the ammunition status of the firearm  105  for one or more operators  110 . The system  100  can further include a global position system (GPS) and an electronic compass to wirelessly transmit a location of the system  100  and a direction that the system  100  is facing to the remote entity  240 . Thus, the remote entity  240  can determine where the operator  110  is located, the direction the system  100 , and likely the operator  110 , is facing, as well as the ammunition status of the firearm  105  associated with the system  100 .
