     DETAILED DESCRIPTION 
     Referring in general to the accompanying drawings, various embodiments of the present disclosure are illustrated to show example embodiments related to power reset. It should be understood that the drawings presented are not meant to be illustrative of actual views of any particular portion of an actual circuit, device, system, or structure, but are merely representations which are employed to more clearly depict various embodiments of the disclosure. 
     The following provides a more detailed description of the present disclosure and various representative embodiments thereof. In this description, functions may be shown in block diagram form in order not to obscure the present disclosure in unnecessary detail. Additionally, block definitions and partitioning of logic between various blocks is exemplary of a specific implementation. It will be readily apparent to one of ordinary skill in the art that the present disclosure may be practiced by numerous other partitioning solutions. For the most part, details concerning timing considerations and the like have been omitted where such details are not necessary to obtain a complete understanding of the present disclosure and are within the abilities of persons of ordinary skill in the relevant art. 
     As will be appreciated, an electronic device may occasionally stop working (e.g., “freeze” or “hang”) and may need to be rebooted by disconnecting and reconnecting (also referred to herein as “toggling”) power to the electronic device. Further, in some cases, an electronic device may include a watchdog timer that monitors a clock signal, and if the clock signal is missing for a predetermined period of time, a reset pulse may be sent to a reset input to reset the electronic device. However, in some cases wherein a watchdog timer stops working (e.g., hangs or freezes), an electronic device may need to be reset by toggling power to the electronic device. 
     As will also be appreciated, in some systems, an electronic device may be remote from other devices (e.g., server and/or a user device) of the system. As a more specific, non-limiting example, a remote unit (e.g., a “mobile unit” or “remote device”), which may include one or more input devices (e.g., sensors, cameras, etc.), one or more output devices (e.g., lights, speakers, etc.), a communication device, a storage device, and/or a controller may be positioned at a first location, and a server and/or one user devices may be positioned at another location, which is remote from the first location. 
     In some conventional systems, when a device (e.g., a controller) of a remote unit (e.g., a mobile, remote unit) fails, a technician is dispatched from a location nearest to, but remote from, that of the remote unit. The technician, after traveling to (e.g., via a vehicle) and arriving on the location of the remote unit, manually disconnects power to the device. After a few seconds, the technician powers the device back on to reset the device. This is not only expensive but may take several days before the remote unit can be reached and the device is restored to full operation. As will be appreciated, downtime of a remote unit is very costly (e.g., to a business due to clients/customers not paying for associated products/services during downtime). 
     Various embodiments of the disclosure relate to resetting a remote device. More specifically, various embodiments relate to momentarily disconnecting power to a remote device and reconnecting power to the remote to reset the remote device. In some embodiments, the power to the remote device may be disconnected and reconnected responsive to a signal generated via a communication device of the remote device. In some embodiments the signal may be generated in response to another signal received from a remote device (e.g., a server or a user device). It is noted that according to implementation and/or configuration of an associated system, the remote device may or may not be automatically reconnected to power. 
     According to various embodiments, circuitry, which may be relatively small, inexpensive, and/or simple, may be configured to disconnect a main power source as well as a backup power source (e.g., simultaneously and momentarily), which may toggle the power and allow the device (and any other associated devices, including the communications device) to reset itself, thereby eliminating the need for a technician to be dispatched to the remote location to manually perform a reset operation. 
     As will be appreciated, after detecting that a remote device is malfunctioning and/or has stopped working, various embodiments disclosed herein may allow for the remote device to be restored (e.g., to full operation) (i.e., via remote control) in a relatively short time period (e.g., within a few seconds or minutes). 
     Embodiments of the disclosure will now be explained with reference to the accompanying drawings. 
       FIG.  1    illustrates an example system  100 , in accordance with various embodiments of the disclosure. System  100  includes a power source  102 , a communication device  104 , circuitry  106 , and a load  108 . For example, power source  102  may include one or more power sources, such as a primary power source (e.g., one or more primary batteries) and a secondary power source (e.g., one or more backup batteries). Further, for example, load  108  may include a controller (also referred to herein as a “control unit” or a “control board”) and/or one or more other devices (e.g., a communication device (e.g., communication device  104 ), one or more sensors (e.g., camera(s), sound detector(s), etc.), one or more output devices (e.g., light(s), speaker(s), etc.), without limitation). Further, for example, communication device  104  may include a modem. Moreover, for example, circuitry  106  may include one or more components (e.g., one or more relays, switches, and/or transistors) for disconnecting load  108  from power source  102  (e.g., responsive to an event). 
     According to some embodiments in which load  108  includes a controller, load  108  may monitor various functions of system  100  and report back to, for example, a server (e.g., a cloud server) (not shown in  FIG.  1   ) or a remote device (not shown in  FIG.  1   ) via communication device  104 . The odds that both load  108  and communication device  104  malfunction and/or stop working at the same time may be very small. In some cases, communication device  104  may be more reliable than load  108 , thus in some scenarios, although load  108  may be malfunctioning, communication device  104  may be functioning properly. 
     In some examples, in the event load  108  stops working (also referred to herein as “malfunctions” or some variation thereof) (e.g., hangs, freezes, fails to respond, etc.), a signal may be sent from communication device  104  to circuitry  106 , and, in response thereto, circuitry  106  may disconnect (e.g., temporarily disconnect) load  108  from power source  102  and reconnect (e.g., automatically after expiration of a time period) power source  102  to load  108  such that load  108  resets. More specifically, during one contemplated operation of system  100 , in response to determining that load  108  is not operating properly (e.g., load  108  has frozen and/or is malfunctioning, etc.), communication device  104  may send a signal (e.g., a pulse signal, such as a high pulse or a low pulse) to circuitry  106  to cause one or more switches of circuitry  106  to temporarily open and, as a result, temporarily electrically decouple load  108  from power source  102 . In some embodiments, after a time period (e.g., a short time period, such as two seconds or less), the one or more switches of circuitry  106  may close and, as a result, load  108  may again electrically couple to power source  102 , thus causing load  108  to reset. 
     According to some embodiments, communication device  104  may send the signal (i.e., the signal to temporarily disconnect power to load  108 ) responsive to an event. For example, an event may include receipt of a signal, which may have originated internally (i.e., within system  100 ) or from another device (e.g., a remote server (e.g., a cloud server) or a remote user device). As another example, an event may include detecting that load  108  has stopped functioning properly (e.g., via a remote device (e.g., a server, a user device, without limitation) and/or via a local device (i.e., local to system  100 )). 
     In some embodiments system  100  may further include a control device (e.g., a CPU, a controller, a watchdog circuit (e.g., a watchdog timer), without limitation) configured to send a signal (e.g., a pulse signal, such as a high pulse or a low pulse) to circuitry  106  to cause one or more switches of circuitry  106  to temporarily open and, as a result, temporarily electrically decouple load  108  from power source  102 . In some embodiments, communication device  104  may include the control device and a modem (e.g., the control device may be separate from a modem). In other embodiments, the control device may be separate from communication device  104 . In these embodiments, communication device  104  may or may not be configured to send a signal (e.g., a pulse signal) to circuitry  106  (e.g., to cause one or more switches of circuitry  106  to temporarily open). 
     According to some embodiments, a reset device (also referred to herein as a “reset module”), which may be coupled between a load (e.g., a controller) and one or more power sources (e.g., a primary battery and/or backup battery), may be configured to disconnect the load from the one or more power sources. In one example, in response to a signal from a communication device, the reset device may disconnect the load from the one or more power sources. As a more specific example, in response to a control signal from a modem, one-shot circuitry of a reset device may be triggered to momentarily open a number of “normally closed” (N.C.) relay contacts and disconnect all power going to a controller of the load. Further, in at least some embodiments, the controller may provide power to the modem, and thus upon the controller being temporarily disconnected from the one or more power sources, the modem may also be temporarily disconnected from the one or more power sources. 
       FIG.  2    illustrates an example system  200 , according to various embodiments of the disclosure. System  200  includes a power source  202 , a power source  204 , a communication device  206 , a reset module  208 , and a load  210 . In one example, power source  202  may include a primary power source (e.g., one or more primary batteries), power source  204  may include a backup power source (e.g., one or more backup batteries), communication device  206  may include a modem (e.g., an enterprise-grade modem (e.g., a Cradlepoint modem) or any other suitable modem), and load  210  may include a controller. 
     According to one non-limiting example, reset module  208  may receive primary power from power source  202  via a node N 1 , and load  210  may receive the primary power (e.g., 24 volts) from reset module  208  via a node N 2 . Further, reset module  208  may receive backup power from power source  204  via a node N 3 , and load  210  may receive the backup power (e.g., via a bus, such as a 24-volt bus) from reset module  208  via a node N 4 . In some embodiments, node N 4  may also be configured to couple to a ground voltage (e.g., via a relay). Moreover, reset module  208  may receive a signal from communication device  206  via a node N 5 , and load  210  may convey power (e.g., 24 volts or any other suitable voltage), via a node N 6 , to communication device  206 . 
     According to various embodiments, responsive to an event, reset module  208  may be configured to disconnect load  210  from each of power source  202  and power source  204 . More specifically, according to various embodiments, responsive to an event, communication device  206  may convey a signal (e.g., a pulse signal or any other type of signal) to reset module  208 , which, in response to receipt of the signal from communication device  206 , may be configured to disconnect load  210  from each of power source  202  and power source  204 . 
       FIG.  3    illustrates an example system  300  including circuitry  302 , in accordance with various embodiments of the disclosure. For example, circuitry  106  of  FIG.  1    and/or reset module  208  of  FIG.  2    may include circuitry  302  of  FIG.  3   . System  300  further includes a power source  304 , a power source  306 , a communication device  308 , and a load  310 . In one example, power source  304  includes a primary power source and power source  306  includes a secondary power source. For example, power source  304  may include one or more primary batteries (e.g., one or more chargeable batteries) and power source  306  may include one or more backup batteries (e.g., one or more chargeable batteries). 
     Circuitry  302 , which in this example is coupled to power source  304 , power source  306 , communication device  308 , and load  310 , includes a number of capacitors C 1 -C 5 , a number of resistors R 1 -R 10 , and a number of transistors M 1 -M 5 . It is noted that transistors M 1  and M 2  may form and/or may collectively be referred to herein as a “one-shot” circuit. Circuitry  302  further includes diodes D 1 -D 4 , a relay RY, which includes an inductor (e.g., a coil) L 1  and a switch S 1 , and a relay RX, which includes an inductor (e.g., a coil) L 2  and a switch S 2 . In one example, each of relay RY and relay RX may include and/or be configured as a normally closed (N.C.) relay. 
     As shown in circuitry  302 , a node N 11  is positioned between an output of communication device  308  and a capacitor C 3 , a node N 12  is positioned between a transistor M 3  and a resistor R 5 , a node N 13  is positioned between a resistor R 3  and a capacitor C 5 , and a node N 14  is positioned between a resistor R 6  and a transistor M 2 . As also shown in circuitry  302 , a node N 15  is coupled to one end of a resistor R 8  (i.e., between a resistor R 7  and resistor R 8 ), a node N 16  is coupled to another end of resistor R 8  (i.e., between resistor R 8  and a transistor M 4 ), and a node N 17  is coupled between an inductor L 1  and a transistor M 5  (e.g., node N 17  is coupled to a collector of transistor M 5 ). Switch S 1  is coupled between power source  306  and load  310 , and switch S 2  is coupled between power source  304  and load  310 . 
     With reference to  FIG.  3   , a contemplated operation of system  300  will now be described. In this contemplated operation, load  310 , which may be part of a unit (e.g., a mobile unit) positioned in a remote location (e.g., a parking lot, a roadside location, a construction zone, a concert venue, a sporting venue, a school campus, without limitation), includes a controller that is not operating properly (e.g., load  310  has frozen). 
     After detecting that load  310  is not operating properly, communication device  308 , which may include a modem, may output a signal, such as a pulse signal. More specifically, for example, an output of communication device  308  (i.e., a signal at node N 11 ), which may be HIGH initially (i.e., in a normal state), may transition LOW for a time period (e.g., a predetermined time period, such as 1 second, 1.5 seconds, 1.8 seconds, 2 seconds, 2.5 seconds, or any other suitable time period), and thereafter the output of communication device  308  (i.e., a signal at node N 11 ) may return to a HIGH state. Responsive to the signal at node N 11  transitioning from HIGH to LOW and back to HIGH, a signal at node N 12  may include an upward spike that turns transistor M 3  ON momentarily causing node N 13  and node N 14  to transition LOW (i.e., node N 13  and node N 14  are momentarily coupled to ground), thus causing a signal at node N 13  and at node N 14  to include a downward spike. Further, responsive to the signal (i.e., the signal generated by communication device  308 ), a signal at node N 15 , which is LOW in the normal state, goes HIGH, thus causing node N 16  to momentarily transition HIGH, which turns ON the Darlington transistor configuration (i.e., including transistors M 4  and M 5 ). 
     Responsive to transistors M 4  and M 5  being ON (i.e., in a conductive state), a node N 17  is coupled to ground and current may flow through inductors L 1  and L 2  to momentarily open switches S 1  and S 2 , and thus momentarily disconnect (e.g., substantially simultaneously disconnect) load  310  from both power source  304  and power source  306 . As will be appreciated, this described operation may allow load  310  and any other associated devices (i.e., devices coupled to load  310 ), including communication device  308  to be reset (also known as “reboot”). Accordingly, in this described example operation, load  310  may be reset responsive to a signal generated via communication device  308  and it is not required for a technician to be dispatched to a location (e.g., a remote location) of load  310  to manually reset (reboot) load  310 . 
     As will be appreciated, various components of circuitry  302  may affect timing, filtering, and/or noise immunity of circuitry  302 . More specifically, capacitors C 1  and C 2  may provide filtering, resistor R 10  may provide noise immunity, and capacitor C 5  and resistors R 2  and R 3  may affect timing of circuitry  302 . Accordingly, as will be appreciated, various component values of circuitry  302  may be varied depending on various factors, such as timing, noise, application, configuration, and/or other factors. In one non-limiting example, values of one or more components of circuitry  302  (e.g., values of capacitor C 5  and resistors R 2  and R 3 ) may be selected such that load  310  is decoupled from primary power source  304  and secondary power source  306  (i.e., prior to being recoupled) for approximately 1.8 seconds, long enough to ensure that power is completely removed from load  310  to cause load  310 , and possibly communication device  308 , to reboot upon being reconnected to power. 
     In one specific, non-limiting example, capacitor C 1  may have a capacitance of approximately 4.7 microfarads (μF), capacitor C 2  may have a capacitance of approximately 0.01 μF, capacitor C 3  may have a capacitance of approximately 2.2 μF, capacitor C 4  may have a capacitance of approximately 0.01 μF, and capacitor C 5  may have a capacitance of approximately 10 μF. Continuing with this non-limiting example, resistor R 1  may have a resistance of approximately 33 kiloohms (kΩ), resistor R 2  may have a resistance of approximately 100 kΩ, resistor R 3  may have a resistance of approximately 1 megaohm (MΩ), resistor R 4  may have a resistance of approximately 100 kΩ, resistor R 5  may have a resistance of approximately 100 kΩ, resistor R 6  may have a resistance of approximately of 1 MΩ, resistor R 7  may have a resistance of approximately of 1 MΩ, resistor R 8  may have a resistance of approximately of 510 kΩ, resistor R 9  may have a resistance of approximately 100 kΩ, and resistor R 10  may have a resistance of approximately 1 kΩ. As will be appreciated, depending on various factors of an associated system and/or circuitry, component values may be varied to carry out various embodiments of the disclosure. 
     It is noted that circuitry  302  is provided as example circuitry to decouple and couple (e.g., recouple) a load from one or more power sources, however the disclosure is not so limited and any suitable circuitry for decoupling and coupling load from one or more power sources may be within the scope of the disclosure. For example, a reset module (e.g., reset module  208  of  FIG.  2   ) may include any suitable circuitry for decoupling and coupling a load from one or more power sources. 
     As noted above with reference to system  100  of  FIG.  1   , in some embodiments, a system may further include a control device (e.g., a CPU, a controller, a watchdog circuit (e.g., a watchdog timer)) (e.g., within communication device  104  or external to communication device  104 ) configured to send a signal (e.g., a pulse signal, such as a high pulse or a low pulse) to circuitry to cause one or more switches of the circuitry to temporarily open and, as a result, temporarily electrically decouple a load from a power source. In embodiments wherein the control device is separate from a communication device (e.g., including a modem), the communication device may or may not be configured to send a signal (e.g., a pulse signal, such as a high pulse or a low pulse) to the circuitry to reset an associated load (e.g., controller). 
       FIG.  4    depicts another example system  400  including a unit  402 , in accordance with various embodiments of the disclosure. Unit  402 , which may also be referred to herein as a “mobile unit,” a “mobile security unit,” a “live unit,” or a “physical unit,” may be configured to be positioned in an environment (e.g., a parking lot, a roadside location, a construction zone, a concert venue, a sporting venue, a school campus, without limitation). In some embodiments, unit  402  may include one or more sensors (e.g., cameras, weather sensors, motion sensors, noise sensors, without limitation)  404  and one or more output devices  406  (e.g., lights, speakers, electronic displays, without limitation). Unit  402  may also include at least one storage device (e.g., internal flash media, a network attached storage device, or any other suitable electronic storage device), which may be configured for receiving and storing data (e.g., video, images, audio, without limitation) captured by one or more sensors of unit  402 . According to some embodiments, unit  402  may include system  100  of  FIG.  1   , system  200  of  FIG.  2   , and/or system  300  of  FIG.  3   . 
     In some embodiments, unit  402  may include a mobile security unit. In these and other embodiments, unit  402  may include a portable trailer  408 , a storage box  410 , and a mast  412  coupled to a head unit  414  which may include for example, one or more batteries, one or more cameras, one or more lights, one or more speakers, and/or one or more microphones. According to some embodiments, a first end of mast  412  may be proximate storage box  410  and a second, opposite end of mast  412  may be proximate, and possibly adjacent, head unit  414 . More specifically, in some embodiments, head unit  414  may be coupled to mast  412  an end opposite an end of mast  412  proximate storage box  410 . 
     In some examples, unit  402  may include one or more primary batteries (e.g., within storage box  410 ) and one or more secondary batteries (e.g., within head unit  414 ). In these embodiments, a primary battery positioned in storage box  410  may be coupled to a load and/or a secondary battery positioned within head unit  414  via, for example, a cord reel. 
     In some embodiments, unit  402  may also include one or more solar panels  416 , which may provide power to one or more batteries of unit  402 . More specifically, according to some embodiments, one or more solar panels  416  may provide power to a primary battery within storage box  410 . Although not illustrated in  FIG.  4   , unit  402  may also include one or more additional power sources, such as one or more generators (e.g., fuel cell generators). 
       FIG.  5    depicts a system  500 , in accordance with various embodiments of the disclosure. System  500  includes a mobile unit  502 , a server  504 , and one or more devices  506 . In one non-limiting example, mobile unit  502  includes mobile unit  402  (see  FIG.  4   ), server  504  may include a cloud server or any other server, and device(s)  506  may include an electronic device, such as a user device (e.g., mobile phone, tablet, etc.), a desktop computer, or any other suitable electronic device (e.g., including a display). According to various embodiments, each of server  504  and device(s)  506  may be remote from mobile unit  502 . 
     According to various embodiments of the present disclosure, mobile unit  502 , which includes a modem (e.g., communication device  104 / 206 / 308 ), may be within a first location (a “camera location” or a “remote location”), and server  504  may be within a second location, remote from the camera location. In addition, in at least some examples, electronic device  506  may be remote from the camera location and/or server  504 . As will be appreciated by a person having ordinary skill in the art, system  200  is modular, expandable, and scalable. 
       FIG.  6    is a flowchart of an example method  600  of rebooting a load of a mobile unit. Method  600  may be arranged in accordance with at least one embodiment described in the disclosure. Method  600  may be performed, in some embodiments, by a device or system, such as system  100  (see  FIG.  1   ), system  200  (see  FIG.  2   ), system  300  (see  FIG.  3   ), unit  402  (see  FIG.  4   ), system  500  (see  FIG.  5   ), or another device or system. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. 
     Method  600  may begin at block  602 , wherein a signal is conveyed from a first location to a modem of a mobile unit positioned at a second location that is remote from the first location, and method  600  may proceed to block  604 . For example, a signal may be conveyed from a server (e.g., a cloud server), a user device, or any other device. As a more specific example, the signal may be conveyed from a server to the modem, which may be part of a mobile unit (e.g., unit  402  of  FIG.  4   ) that is remote from the server. 
     At block  604 , a control signal is generated at the modem, and method  600  may proceed to block  606 . For example, the control signal may include a pulse signal generated by the modem responsive to receipt of the signal conveyed to the modem (e.g., from a remote server or a remote user device). For example, the modem, which may include a default output in a HIGH state, may generate a downward (“low”) pulse (e.g., transitioning from HIGH to LOW and back to HIGH). As a more specific example, the modem, which may be part of a mobile unit (e.g., unit  402  of  FIG.  4   ), may generate the pulse signal. In other embodiments, the control signal may include an upward (“high”) pulse (e.g., transitioning from LOW to HIGH and back to LOW). 
     At block  606 , responsive to the control signal, a load of the mobile unit is disconnected from at least one battery of the mobile unit, and method  600  may proceed to block  608 . For example, the load may include a controller. Further, for example, the load may be disconnected from a first power source (e.g., one or more primary batteries) and possibly a second power source (e.g., one or more backup batteries) of the mobile unit. As a more specific example, the control signal may be received at a reset module (e.g., module  208  of  FIG.  2   ), which may part of the mobile unit (e.g., unit  402  of  FIG.  4   ) and may include circuitry (e.g., circuitry  302  of  FIG.  3   ) that may be configured for disconnecting the load from at least one battery (e.g., primary power source  304  and secondary power source  306  of  FIG.  3   ) of the mobile unit. 
     At block  608 , the load may reconnect to the at least one battery. For example, the load may automatically reconnect to the at least one battery after expiration of a time period (e.g., 1 second, 1.5 seconds, 1.8 seconds, 2 seconds, without limitation), which may be predetermined based on one or more circuit values of associated circuitry (e.g., circuitry  302  of  FIG.  3   ). 
     Modifications, additions, or omissions may be made to method  600  without departing from the scope of the present disclosure. For example, the operations of method  600  may be implemented in differing order. Furthermore, the outlined operations and actions are only provided as examples, and some of the operations and actions may be optional, combined into fewer operations and actions, or expanded into additional operations and actions without detracting from the essence of the disclosed embodiment. 
     As will be appreciated by persons having ordinary skill in the art, in contrast to conventional systems, devices, circuitry, and methods, which require a user to travel to a remote location of a mobile unit to manually reset a controller of the mobile unit, various embodiments may enable a user to remotely reset a device (e.g., a controller of a mobile unit). Thus, as will be appreciated by a person having ordinary skill in the art, various embodiments may save time and may reduce costs associated with the mobile unit. Further, various embodiments may increase uptime of a remote unit. 
     In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the disclosure are not meant to be actual views of any particular apparatus (e.g., circuit, device, system, etc.) or method, but are merely idealized representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., circuit, device, or system) or all operations of a particular method. 
     Terms used herein and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.). 
     Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. As used herein, “and/or” includes any and all combinations of one or more of the associated listed items. 
     In addition, even if a specific number of an introduced claim recitation is explicitly recited, it is understood that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc. For example, the use of the term “and/or” is intended to be construed in this manner. 
     Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.” 
     As used herein, the term “approximately” or the term “substantially” in reference to a given parameter, property, or condition means and includes to a degree that one of ordinary skill in the art would understand that the given parameter, property, or condition is met with a degree of variance, such as within acceptable tolerances. By way of example, depending on the particular parameter, property, or condition that is substantially met, the parameter, property, or condition may be at least 90.0 percent met, at least 95.0 percent met, at least 99.0 percent met, at least 99.9 percent met, or even 100.0 percent met. 
     As used herein, the term “approximately” or the term about,&#39; when used in reference to a numerical value for a particular parameter, is inclusive of the numerical value and a degree of variance from the numerical value that one of ordinary skill in the art would understand is within acceptable tolerances for the particular parameter. For example, “about,” in reference to a numerical value, may include additional numerical values within a range of from 90.0 percent to 110.0 percent of the numerical value, such as within a range of from 95.0 percent to 105.0 percent of the numerical value, within a range of from 97.5 percent to 102.5 percent of the numerical value, within a range of from 99.0 percent to 101.0 percent of the numerical value, within a range of from 99.5 percent to 100.5 percent of the numerical value, or within a range of from 99.9 percent to 100.1 percent of the numerical value, 
     Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms “first,” “second,” “third,” etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. 
     The embodiments of the disclosure described above and illustrated in the accompanying drawings do not limit the scope of the disclosure, which is encompassed by the scope of the appended claims and their legal equivalents. Any equivalent embodiments are within the scope of this disclosure. Indeed, various modifications of the disclosure, in addition to those shown and described herein, such as alternative useful combinations of the elements described, will become apparent to those skilled in the art from the description. Such modifications and embodiments also fall within the scope of the appended claims and equivalents.
