DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
Referring generally to FIGS. 1A through 2L, a system 100 for determining a state of operational readiness of a fuel cell backup system of a nuclear reactor system is described in accordance with the present disclosure. One or more fuel cell monitoring systems 102 may monitor a readiness state (e.g., temperature, pressure, humidity, or electrical output) of a portion of a fuel cell system 106 associated with a nuclear reactor system 108 (e.g., fuel cell system provides backup power to an operation system 109 of the nuclear reactor system 108). Then, the monitoring system may transmit a signal 110 indicative of the state of readiness of the fuel cell system 106 to a readiness determination system 112. In response to the signal 110 transmitted by the monitoring system 102, the readiness determination system 112 may provide an operational readiness determination by comparing the monitored readiness state of the fuel cell system 106 to an established readiness state of the fuel cell system 106. The established readiness state may be a function (e.g., variable function) of one or more characteristics (e.g., operational characteristic or design characteristic) of the nuclear reactor system 108. In some embodiments, the readiness determination system 112 may transmit a signal 114 indicative of the operational readiness determination to a fuel cell control system 116. In response to the signal transmitted 114 by the readiness determination system 112, the fuel cell control system 116 may adjust one or more characteristics (e.g., characteristic of one or more individual fuel cells 122 of the fuel cell system 106) of the fuel cell system 106.
Referring now to FIG. 1B, the system 100 for providing a readiness determination may include a fuel cell monitoring system 102 configured to monitor a readiness state of the fuel cell block 117 of the fuel cell system. For example, the monitoring system 102 may monitor a readiness state of a portion of the fuel cell block 117 of a fuel cell system 106 associated with a nuclear reactor system 108. Then, the monitoring system may transmit a signal 110 indicative of the state of readiness of the fuel cell system 106 to a readiness determination system 112. In response to the signal 110 transmitted by the monitoring system 102, the readiness determination system 112 may provide an operational readiness determination by comparing the monitored readiness state of the fuel cell system 106 to an established readiness state of the fuel cell system 106.
In a further embodiment, the portion of the fuel cell block 117 may include one or more fuel cell modules 118 of the fuel cell system 106. For example, the monitoring system 102 may monitor a readiness state of a portion of one or more fuel cell modules 118 of a fuel cell system 106 associated with a nuclear reactor system 108. For instance, the fuel cell monitoring system 102 may independently monitor each fuel cell module 118 of a plurality of fuel cell modules of the fuel cell system 106. As a result, the fuel cell monitoring system 102 may monitor the state of readiness of the fuel cell system 106 by monitoring the individual fuel cell modules 118 of the fuel cell system 106. Then, the monitoring system may transmit a signal 110 indicative of the state of readiness of the fuel cell system 106 to a readiness determination system 112. Moreover, the signal indicative of the fuel cell system 106 readiness may also transmit the readiness of the individual fuel cell modules 118 of the fuel cell system 106 to a readiness determination system 112. In response to the signal 110 transmitted by the monitoring system 102, the readiness determination system 112 may provide an operational readiness determination by comparing the monitored readiness state of the fuel cell system 106 to an established readiness state of the fuel cell system 106. This operational readiness determination may include an operational readiness determination of the entire fuel cell system 106 or an operational readiness determination of the individual fuel cell system modules 118.
In a further embodiment, the portion of the fuel cell block 117 may include one or more fuel cell stacks 120 of the fuel cell system 106. For example, the monitoring system 102 may monitor a readiness state of a portion of one or more fuel cell stacks 118 of a fuel cell system 106 associated with a nuclear reactor system 108. For instance, the monitoring system 102 may monitor the temperature of the bipolar plates between two adjacent fuel cells 122 of a fuel cell stack 120. Further, the fuel cell monitoring system 102 may independently monitor each fuel cell stack 120 of one or more fuel cell modules 122 of the fuel cell system 106. The fuel cell monitoring system 102 may monitor the state of readiness of the fuel cell system 106 by monitoring the individual fuel cell stacks 120 of the fuel cell system 106. Then, the monitoring system may transmit a signal 110 indicative of the state of readiness of the fuel cell system 106 to a readiness determination system 112. Moreover, the signal indicative of the fuel cell system 106 readiness state may also transmit the readiness state of the individual fuel cell stacks 120 of the fuel cell system 106 to a readiness determination system 112. In response to the signal 110 transmitted by the monitoring system 102, the readiness determination system 112 may provide an operational readiness determination by comparing the monitored readiness state of the fuel cell system 106 to an established readiness state of the fuel cell system 106. This operational readiness determination may include an operational readiness determination of the entire fuel cell system 106 or an operational readiness determination of the individual fuel cell stacks 120 of the fuel cell system 106.
In a further embodiment, the portion of the fuel cell block 117 may include one or more fuel cells 122 of one or more fuel cell stacks 120 of the fuel cell system 106. For example, the monitoring system 102 may monitor a readiness state of a portion of one or more fuel cells 122 of a fuel cell system 106 associated with a nuclear reactor system 108. For instance, the monitoring system 102 may monitor the readiness state, such as the temperature or humidity, of a fuel cell membrane of one or more fuel cells 122 of the fuel cell system 106. In another instance, the monitoring system 102 may monitor one or more electrical characteristics, such as current output, voltage, or resistance, of one or more fuel cells 122 of the fuel cell system 106. Further, the fuel cell monitoring system 102 may independently monitor each fuel cell 122 of one or more fuel cell stacks 120 of the fuel cell system 106. The fuel cell monitoring system 102 may monitor the state of readiness of the fuel cell system 106 by monitoring the individual fuel cells 122 of the one or more fuel cell stacks 120 of the fuel cell system 106. Then, the monitoring system may transmit a signal 110 indicative of the state of readiness of the fuel cell system 106 to a readiness determination system 112. Moreover, the signal indicative of the fuel cell system 106 readiness state may also transmit the readiness state of the individual fuel cells 122 of the fuel cell system 106 to a readiness determination system 112. In response to the signal 110 transmitted by the monitoring system 102, the readiness determination system 112 may provide an operational readiness determination by comparing the monitored readiness state of the fuel cell system 106 to an established readiness state of the fuel cell system 106. This operational readiness determination may include an operational readiness determination of the entire fuel cell system 106 or an operational readiness determination of the individual fuel cells 122 of the fuel cell system 106.
In some embodiments, the portion of the fuel cell system 106 may include a reactant gas of the fuel cell system 106. For example, the monitoring system 102 may monitor a readiness state of a reactant gas 124 of a fuel cell system 106 associated with a nuclear reactor system 108. For instance, the monitoring system 102 may monitor the readiness state, such as the temperature, pressure, or humidity, of a reactant gas 124 (e.g., fuel or oxidant) of the fuel cell system 106. Then, the monitoring system may transmit a signal 110 indicative of the state of readiness of the fuel cell system 106 to a readiness determination system 112. In response to the signal 110 transmitted by the monitoring system 102, the readiness determination system 112 may provide an operational readiness determination by comparing the monitored readiness state of the fuel cell system 106 to an established readiness state of the fuel cell system 106.
Referring now to FIG. 1C, the fuel cell monitoring system 102 may include, but is not limited to, a thermal monitoring system 126, a pressure monitoring system 128, a humidity monitoring system 130, or an electrical monitoring system 132. For example, a thermal monitoring system 126 (e.g., thermocouple device communicatively coupled to a computer controlled data management system) may monitor one or more thermal characteristics (e.g., temperature or rate of change of temperature) of a portion (e.g., portion of one or more fuel cells 104) of one or more fuel cells 122 of the fuel cell system 106 associated with a nuclear reactor system 108. For instance, the thermal monitoring system 126 may monitor the temperature of the fuel cell membrane of one or more fuel cells 122 of the fuel cell system 106. Then, the thermal monitoring system 126 may transmit a signal 110 indicative of the fuel cell membrane temperature of the one or more fuel cells 122 of the fuel cell system 106 to a readiness determination system 112. In another instance, the thermal monitoring system 126 may monitor the temperature of one or more bipolar plates of one or more fuel cells 122 of one or more fuel cell stacks 120 of the fuel cell system 106. Then, the thermal monitoring system 126 may transmit a signal 110 indicative of the temperature of one or more bipolar plates of one or more fuel cell stacks 120 of the fuel cell system 106 to a readiness determination system 112.
By way of another example, a pressure monitoring system 128 may monitor one or more pressure characteristics (e.g., pressure or rate of change of pressure) of a portion of the fuel cell system 106 associated with a nuclear reactor system 108. For instance, the pressure monitoring system 128 may monitor the pressure in one or more fuel cells 122 of the fuel cell system 106. Then, the pressure monitoring system 128 may transmit a signal 110 indicative of the fuel cell pressure of the one or more fuel cells 122 of the fuel cell system 106 to a readiness determination system 112. In another instance, the pressure monitoring system 128 may monitor the pressure of one or more of the reactant gas streams 124 (e.g., fuel stream or oxidant stream) of the fuel cell system 106. Then, the pressure monitoring system 128 may transmit a signal 110 indicative of the gas pressure of one or more of the reactants 124 of the fuel cell system 106 to a readiness determination system 112.
In another example, a humidity monitoring system 130 may monitor one or more humidity characteristics (e.g., humidity level or rate of change of humidity level) of a portion of the fuel cell system 106 associated with a nuclear reactor system 108. For instance, the humidity monitoring system 130 may monitor the humidity in one or more fuel cells 122 of the fuel cell system 106. Then, the humidity monitoring system 130 may transmit a signal 110 indicative of the humidity of the one or more fuel cells 122 of the fuel cell system 106 to a readiness determination system 112. Further, the humidity monitoring system 130 may monitor the humidity of the fuel cell membrane of one or more fuel cells 122 of the fuel cell system 106. Then, the humidity monitoring system 130 may transmit a signal 110 indicative of the humidity of the fuel cell membrane of the one or more fuel cells 122 of the fuel cell system 106 to a readiness determination system 112.
In an additional example, an electrical monitoring system 132 may monitor one or more electrical characteristics (e.g., electrical current 134, voltage 136, capacitance 137 or resistance 138, rate of change of electrical current, rate of change of voltage, or rate of change of resistance) of one or more fuel cells 122 of the fuel cell system 106 associated with a nuclear reactor system 108. For instance, the electrical monitoring system 132 may include a monitoring system 134 configured to monitor the electrical current output of one or more fuel cells 122 of the fuel cell system 106. Upon measuring the electrical current output of one or more fuel cells 122 of the fuel cell system 106, the electrical current monitoring system 134 may transmit a signal 110 indicative of the electrical current of the one or more fuel cells 122 of the fuel cell system 106 to a readiness determination system 112. In another instance, the electrical monitoring system 132 may include a monitoring system 136 configured to monitor the voltage of one or more fuel cells 122 of the fuel cell system 106. Upon measuring the voltage of one or more fuel cells 122 of the fuel cell system 106, the electrical voltage monitoring system 136 may transmit a signal 110 indicative of the voltage of the one or more fuel cells 104 of the fuel cell system 106 to a readiness determination system 112. In an additional instance, the electrical monitoring system 132 may include a monitoring system 138 configured to monitor the electrical resistance of one or more fuel cells 122 of the fuel cell system 106. Upon measuring the electrical resistance of one or more fuel cells 104 of the fuel cell system 106, the electrical resistance monitoring system 138 may transmit a signal 110 indicative of the electrical resistance of the one or more fuel cells 122 of the fuel cell system 106 to a readiness determination system 112. Further, the electrical monitoring system 132 may include a monitoring system 138 configured to monitor the capacitance of one or more fuel cells 122 of the fuel cell system 106. Upon measuring the capacitance of one or more fuel cells 122 of the fuel cell system 106, the capacitance monitoring system 137 may transmit a signal 110 indicative of the capacitance of the one or more fuel cells 122 of the fuel cell system 106 to a readiness determination system 112.
Referring now to FIG. 1D, the fuel cell monitoring system 102 may include, but is not limited to, a periodic monitoring system 140 configured to periodically monitor a readiness state of the fuel cell system 106. For example, a periodic monitoring system 140 may periodically monitor a portion of the fuel cell system 106. For instance, the temporal frequency with which the periodic monitoring system 140 monitors a portion of the fuel cell system 106 may be preselected by an operator of the fuel cell system 106. In another instance, the frequency with which the periodic monitoring system 140 monitors a portion of the fuel cell system 106 may be a function of a characteristic of the nuclear reactor system. For example, as the operating temperature of the reactor core of the nuclear reactor system 108 increases the frequency with which the periodic monitoring system 140 monitors a portion of the fuel cell control system may increase. Upon monitoring the fuel cell system 106, the periodic monitoring system 140 may transmit a signal 110 indicative of the readiness state of the fuel cell system 106 to a readiness determination system 112.
In additional embodiments, the fuel cell monitoring system 102 may include, but is not limited to, a continuous monitoring system 142 configured to continuously monitor a readiness state of the fuel cell system 106. For example, a continuous monitoring system 142 may continuously monitor a portion of the fuel cell system 106. For instance, a temperature monitoring system 126 may continuously monitor the temperature of one or more bipolar plates of one or more fuel cell stacks 120 of the fuel cell system 106. Then, the continuous monitoring system 142 may transmit one or more signals 110 indicative of the readiness state of the fuel cell system 106 to a readiness determination system 112.
In other embodiments, the fuel cell monitoring system 102 may include, but is not limited to, a comparative monitoring system 144 configured to comparatively monitor a readiness state of the fuel cell system 106. For example, a comparative monitoring system 142 may comparatively monitor a portion of the fuel cell system 106. For instance, a thermal monitoring system 126 may comparatively monitor the temperature of one or more bipolar plates of one or more fuel cell stacks 120 of the fuel cell system 106. Then, the comparative monitoring system 142 may transmit one or more signals 110 indicative of the readiness state of the fuel cell system 106 to a readiness determination system 112.
In some embodiments, the fuel cell monitoring system 102 may include, but is not limited to, a monitoring system 146 configured to monitor a readiness state of the fuel cell system in response to an adjusted characteristic of the nuclear reactor system 108. For example, a monitoring system 146 configured to monitor a readiness state of the fuel cell system 106 in response to an adjusted nuclear reactor characteristic may monitor a readiness state of the fuel cell system 106. For instance, upon adjusting the power level of the nuclear reactor system 108, a monitoring system 146 may monitor a portion of the fuel cell system 106. In another instance, upon adjusting the coolant flow of a coolant system of the nuclear reactor system 108, a monitoring system 146 may monitor a portion of the fuel cell system 106. Then, the monitoring system may transmit a signal 110 indicative of the state of readiness of the fuel cell system 106 to a readiness determination system 112. It should be recognized that the monitoring system 146 may be used to verify that a fuel cell system 106 may provide the appropriate operational readiness in the event a nuclear reactor status is changed. This allows anticipated changes to a nuclear reactor system 108 to occur only when the operator (or an operation system) can verify, using the monitoring system 146, that the fuel cell system 106 is capable of providing sufficient auxiliary power in the even of an emergency situation.
Moreover, the monitoring system 146 configured to monitor a readiness state in response to an adjusted nuclear reactor characteristic may monitor a readiness state of the fuel cell system 106 before, during, or after the characteristic of the nuclear reactor system is adjusted. For example, the monitoring system 146 configured to monitor a readiness state in response to an adjusted nuclear reactor characteristic may monitor the electrical output (e.g., electrical current output or voltage) of one or more fuel cells 122 of the fuel cell system 106 prior to an operation system 109 of the nuclear reactor system 108 adjusts a condition of the nuclear reactor system 108. For instance, prior to adjusting a characteristic of the nuclear reactor system 108, a control system of the nuclear reactor system 108 may transmit a signal to the monitoring system 102 of the fuel cell system 106 directing the monitoring system 102 to monitor a readiness state of the fuel cell system 106. Then, the monitoring system 102 may monitor the readiness state of the fuel cell system 106 and transmit that monitored readiness state to a readiness determination system 112. The readiness determination system may then provide a readiness determination of the fuel cell system 106 and transmit that readiness determination to an operation system of the nuclear reactor system 108, such as the control system. Based on the readiness determination provided by the readiness determination system 112, the control system (or the operator of the nuclear reactor system) may determine whether adjusting the characteristic of the nuclear reactor system 108 is appropriate.
Referring now to FIG. 1E, the monitoring system 102 may be communicatively coupled to a readiness determination system 112, an operator interface system 146, a computer data management system 148 or a safety system 149 of the fuel cell system 106. For example, the monitoring system 102 may include a monitoring system transmission module 147 (e.g., a transmitter, a network port, or the like) configured to transmit a digital or analog signal 110, such as a wireline (e.g., copper wire or fiber optic line) or a wireless (e.g., radio frequency signal) signal from the monitoring system 102 to the readiness determination system 112. For instance, the monitoring system 102 may monitor a readiness state of the fuel cell system 106. Then, the monitoring system transmission module 147 may transmit a signal 110 (e.g., a signal indicative of the monitored readiness state) to the readiness determination system 112. In response to the signal 110 transmitted from the monitoring system transmission module 147, the readiness determination system 112 may provide a readiness determination of the fuel cell system 106.
By way of another example, the monitoring system 102 may include a monitoring system transmission module 147 configured to transmit a digital or analog signal 150 from the monitoring system 102 to an operator interface system 146 of the fuel cell system 106. For instance, the monitoring system 102 may monitor a readiness state of the fuel cell system 106. Then, the monitoring system transmission module 147 of the monitoring system 102 may transmit a signal 150 (e.g., a signal indicative of the monitored readiness state) to an operator controlled computer system 145 equipped with a visual or audio output device (e.g., computer terminal equipped with display system).
In an additional example, the monitoring system may include a monitoring system transmission module 147 configured to transmit a digital or analog signal 151 from the monitoring system to a computer data management system 148. For instance, the monitoring system 102 may monitor a readiness state of the fuel cell system 106. Then, the monitoring system transmission module 147 of the monitoring system 102 may transmit a signal 151 to a computer data management system 148 configured to archive the monitored readiness state data of the fuel cell system 106. Further, the monitoring system transmission module 147 of the monitoring system 102 may transmit a signal 151 to a data management system maintained on a computer network, wherein the data management system is configured to archive the monitored readiness state data of the fuel cell system 106.
In another example, the monitoring system may include a monitoring system transmission module 147 configured to transmit a digital or analog signal 152 from the monitoring system to a safety system 149 of the fuel cell system 106. For instance, the monitoring system 102 may monitor a readiness state of the fuel cell system 106. Then, the monitoring system transmission module 147 of the monitoring system 102 may transmit a signal 152 to a safety system 149 of the fuel cell system 106.
In a further embodiment, the safety system 149 of the fuel cell system 106 may be communicatively coupled to a warning system 153 of the fuel cell system 106. For instance, the monitoring system 102 may monitor a readiness state of the fuel cell system 106. Then, the monitoring system transmission module 147 of the monitoring system 102 may transmit a signal 152 to a safety system 152 of the fuel cell system 106. In turn, the safety system 149 of the fuel cell system 106 may transmit a signal 154 to a warning system, such as an alarm system, of the fuel cell system 106.
Further, the warning system 153 communicatively coupled to the safety system 154 of the fuel cell system 106 may transmit a signal 155 to an operation system 109 of the nuclear reactor system 108.

It is further contemplated that solid oxide fuel cells, which have an optimal operating temperature (approximately 600 to 1000° C.) much higher than PEM fuel cells, may be implemented in the context of a high temperature gas reactor, wherein the heat rejection occurs at a higher temperature than in PWR and BWR reactor systems.

For instance, in response to the signal 111 indicative of the readiness determination transmitted by the readiness determination system 112, a reactant valve control system 250 of the reactant control system 204 of the fuel cell control system 116 may adjust the flow rate of one or more of the reactant gases by controlling one or more reactant valves of the fuel cell system 106.
It will be recognized by those skilled in the art that reactant pump control system 248 and the reactant valve control system 250 may be used independently or in conjunction with one another to adjust the flow rate or pressure of the fuel gas or oxidant gas of the fuel cell system 106. In addition, it should be recognized that by adjusting the pressure or flow rate of the reactant gases a fuel cell control system 116 may adjust one or more characteristics of the fuel cell system 106. For example, the voltage and current output levels of a given fuel cell system 106 may be adjusted by increasing or decreasing the reactant pressure in one or more fuel cells 122 of the fuel cell system 106. By way of another example, the temperature of one or more fuel cells may be adjusted by changing the flow rate of the reactant gases. For instance, given a reactant gas held at ambient temperatures, the fuel cell control system 116 may decrease the temperature of a fuel cell membrane of one or more fuel cells 122 at elevated temperatures by increasing the flow rate of the reactant gases being fed into the fuel cell 122. By way of an additional example, the humidity level of one or more fuel cells may be adjusted by changing the flow rate of the reactant gases. For instance, given a reactant having a first humidity level, the fuel cell control system 106 may decrease or increase the humidity level in a fuel cell membrane by increasing or decreasing the flow rate of the reactant gas being fed into the fuel cell 122. The preceding description should not be interpreted as a limitation but rather an illustration as it is contemplated that a number of other implementations of the present invention may be applicable in related contexts.
In another embodiment, the reactant control system 204 of the fuel cell control system 106 may be used to pre-load a reactant into one or more fuel cells 122 of the fuel cell system 106. For example, in response to the signal 111 indicative of the readiness determination transmitted by the readiness determination system 112, a reactant control system 204 of the fuel cell control system 116 may establish a condition in the fuel cell system 106 by pre-loading a reactant into the fuel cell system 106. For instance, in response to a heightened temperature level measurement of the nuclear reactor core of the nuclear reactor system 108, the reactant control system 204 may pre-load fuel into the fuel cells 122 of the fuel cell system 106. By pre-loading fuel into the fuel cell system 106 the response time required for the fuel cell system 106 to respond to a nuclear reactor system 108 malfunction may be shortened.
In another embodiment, the reactant control system 204 of the fuel cell control system 116 may be used to unload a reactant from one or more fuel cells 122 of the fuel cell system 106. For example, in response to the signal 111 indicative of the readiness determination transmitted by the readiness determination system 112, a reactant control system 204 of the fuel cell control system 106 may adjust a characteristic of the fuel cell system by unloading a reactant from the fuel cell system 106. The response time required for a given fuel cell system at lower nuclear reactor core temperatures is smaller than the response time required for the fuel cell system at higher temperature. In response to a lowered nuclear reactor core temperature level measurement, the reactant control system 204 may unload fuel from the fuel cells of the fuel cell system 106.
In another embodiment, the reactant control system 204 of the fuel cell control system 116 may include a reactant supply control system 252 configured to adjust one or more supply conditions of one or more of the reactant gases of the fuel cell system 106.

Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.
In some implementations described herein, logic and similar implementations may include software or other control structures. Electronic circuitry, for example, may have one or more paths of electrical current constructed and arranged to implement various functions as described herein.

In some variants, for example, implementations may include an update or modification of existing software or firmware, or of gate arrays or programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation may include special-purpose hardware, software, firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components. Specifications or other implementations may be transmitted by one or more instances of tangible transmission media as described herein, optionally by packet transmission or otherwise by passing through distributed media at various times.
Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of virtually any functional operations described herein. In some variants, operational or other logical descriptions herein may be expressed as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, implementations may be provided, in whole or in part, by source code, such as C++, or other code sequences. In other implementations, source or other code implementation, using commercially available and/or techniques in the art, may be compiled/implemented/translated/converted into a high-level descriptor language (e.g., initially implementing described technologies in C or C++ programming language and thereafter converting the programming language implementation into a logic-synthesizable language implementation, a hardware description language implementation, a hardware design simulation implementation, and/or other such similar mode(s) of expression). For example, some or all of a logical expression (e.g., computer programming language implementation) may be manifested as a Verilog-type hardware description (e.g., via Hardware Description Language (HDL) and/or Very High Speed Integrated Circuit Hardware Descriptor Language (VHDL)) or other circuitry model which may then be used to create a physical implementation having hardware (e.g., an Application Specific Integrated Circuit).

Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar is intended to be representative of its class, and the non-inclusion of specific components (e.g., operations), devices, and objects should not be taken limiting.

Those skilled in the art will appreciate that, in general, the same may be said of “sender” and/or other entity-oriented terms as such terms are used herein unless context dictates otherwise.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.
The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures may be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components, and/or wirelessly interactable, and/or wirelessly interacting components, and/or logically interacting, and/or logically interactable components.
In some instances, one or more components may be referred to herein as “configured to,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that such terms (e.g., “configured to”) can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.
While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. It will be understood by those within the art that, in general, 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.). It will be further understood by those within the art that 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 claims 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 typically 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. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically 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.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/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 unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.
With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.
