Other embodiments are described and claimed. 
     Various embodiments may comprise one or more elements. An element may comprise any structure arranged to perform certain operations. Each element may be implemented as hardware, software, or any combination thereof, as desired for a given set of design parameters or performance constraints. Although an embodiment may be described with a limited number of elements in a certain topology by way of example, the embodiment may include more or less elements in alternate topologies as desired for a given implementation. It is worthy to note that any reference to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrases “in one embodiment,” “in some embodiments,” and “in various embodiments” in various places in the specification are not necessarily all referring to the same embodiment.

       FIG. 1  illustrates an example of an operating environment  100  such as may be representative of various embodiments. In operating environment  100 , a wireless communication device (WCD)  102  may wirelessly communicate in a wireless network  103 . Wireless communication devices  104 - 1 ,  104 - 2 ,  104 - 3 ,  104 - 4 ,  104 - 5 , and  104 - 6  may also wirelessly communicate in wireless network  103  and/or with wireless communication device  102 . In various embodiments, wireless network  103  may comprise a wireless network that utilizes wireless channel frequencies of the 60 GHz band. In some embodiments, wireless communication devices within wireless network  103  may communicate with each other according to one or more standards for 60 GHz wireless communications. For example, in various embodiments, devices within wireless network  103  may communicate with each other according to one or more protocols and/or procedures defined in IEEE 802.11ad-2012, and/or its predecessors, revisions, progeny, and/or variants. In some embodiments, wireless communication devices  102 ,  104 - 1 ,  104 - 2 ,  104 - 3 ,  104 - 4 , and  104 - 5  may comprise 60 GHz-capable stations (STAs) such as Directional Multi-Gigabit (DMG) stations (STAs) or enhanced DMG (EDMG) STAs. In various embodiments, some or all of the wireless communication devices within wireless network  103  may communicate with each other according to one or more protocols and/or procedures that may be defined in the IEEE 802.11ay standard that is currently under development. In some embodiments, wireless communication device  102  may operate as a personal basic service set (PBSS) control point/access point (PCP/AP). In various embodiments, wireless communication devices  104 - 1 ,  104 - 2 ,  104 - 3 ,  104 - 4 , and  104 - 5  may operate as non-PCP/AP STAs. The embodiments are not limited in this context. 
       FIG. 2  illustrates an example of a channelization scheme  200  that may be representative of a channelization scheme that may be utilized by a wireless communication protocol implemented in wireless network  103  of  FIG. 1  according to various embodiments. According to channelization scheme  200 , a plurality of wireless channels are defined, each of which corresponds to a different respective sub-band of a 60 GHz frequency band  201 . 60 GHz frequency band  201  spans from a lowest included frequency f L  to a highest included frequency f H , and thus comprises a bandwidth BW that is equal to f H −f L . 
     As reflected in  FIG. 2 , the channels defined by channelization scheme  200  may include channels corresponding to sub-bands of various sizes. In this example, channelization scheme  200  defines non-overlapping 2.16 GHz channels 1, 2, 3, 4, 5, and 6, each of which corresponds to a different respective 2.16 GHz sub-band. These 2.16 GHz channels may be referred to as the “base” channels of channelization scheme  200 . Also shown are various “wide” channels, each of which corresponds to a respective sub-band comprising the combined bandwidth of two or more base channels. In this example, the wide channels defined by channelization scheme  200  include 4.32 GHz channels 9, 11, and 13, 6.48 GHz channels 17 and 20, and 8.64 GHz channel 25. Communication via any particular wide channel may generally be implemented by bonding two or more contiguous base channels and modulating across the combined bandwidth of those bonded channels. In this context, the two or more 2.16 GHz base channels that are bonded may be referred to as the “bonded channel set.” For example, with respect to 8.64 GHz channel 25, the bonded channel set may comprise 2.16 GHz channels 1, 2, 3, and 4. The identities of the twelve channels depicted in  FIG. 2 , their sizes, and the bonded channel sets associated with the various wide channels are summarized in Table 1.

     In various embodiments, channelization scheme  200  may be designed to conform to a rule that wide channels are not to overlap in the frequency domain. In some other embodiments, channelization scheme  200  may permit overlap between wide channels, and may define additional wide channels not depicted in  FIG. 2 . In an example embodiment in which overlap between wide channels is permitted, in addition to the twelve channels listed in Table 1, channelization scheme  200  may define the six wide channels listed in Table 2, and thus a total of 18 channels. The embodiments are not limited to this example.

       FIG. 3  illustrates an example of a channelization scheme  300  that may be representative of a channelization scheme that may be utilized by a wireless communication protocol implemented in wireless network  103  of  FIG. 1  according to various embodiments. Like channelization scheme  200  of  FIG. 2 , channelization scheme  300  defines a plurality of wireless channels, including channels corresponding to sub-bands of various sizes. Each wireless channel defined by channelization scheme  300  corresponds to a different respective sub-band of a 60 GHz frequency band  301 . 60 GHz frequency band  301  spans from a lowest included frequency f L ′ to a highest included frequency f H ′, and thus comprises a bandwidth BW′ that is equal to f H ′-f L ′. 
     According to some embodiments, the bandwidth BW′ of 60 GHz frequency band  301  may be larger than the bandwidth BW of 60 GHz frequency band  201 , which may enable the definition/inclusion of additional channels relative to channelization scheme  200  of  FIG. 2 . In various embodiments, the lowest included frequency f L ′ of 60 GHz frequency band  301  may be lower than the lowest included frequency f L  of 60 GHz frequency band  201  of  FIG. 2 . In some such embodiments, the highest included frequency f H ′ of 60 GHz frequency band  301  may be equal to the highest included frequency f H  of 60 GHz frequency band  201  of  FIG. 2 . In other embodiments in which f L′ &lt;f L , f H ′ may differ from f H . In various embodiments, the highest included frequency f H ′ of 60 GHz frequency band  301  may be greater than the highest included frequency f H  of 60 GHz frequency band  201  of  FIG. 2 . In some such embodiments, f L′  may be equal to f L . In other embodiments in which f H ′&gt;f H , f L′  may differ from f L . The embodiments are not limited in this context. 
     In the example depicted in  FIG. 3 , 60 GHz frequency band  301  is large enough to accommodate eight non-overlapping 2.16 GHz base channels—channels 1, 2, 3, 4, 5, 6, 7, and 8. Also defined are various wide channels, including 4.32 GHz channels 9, 11, 13, and 15, 6.48 GHz channels 17 and 21, and 8.64 GHz channels 25 and 29. The identities of the sixteen channels depicted in  FIG. 3 , their sizes, and the bonded channel sets associated with the various wide channels are summarized in Table 3.

     In various embodiments, channelization scheme  300  may be designed to conform to a rule that wide channels are not to overlap in the frequency domain. In various other embodiments, channelization scheme  300  may permit overlap between wide channels, and may define additional wide channels not depicted in  FIG. 3 . In an example embodiment in which overlap between wide channels is permitted, in addition to the sixteen channels listed in Table 3, channelization scheme  300  may define the ten wide channels listed in Table 4, and thus a total of 26 channels. The embodiments are not limited to this example.

       FIG. 4  illustrates an example of an operating environment  400  such as may be representative of various embodiments. In operating environment  400 , wireless communication device  102  may identify data that is to be provided to wireless communication device  104 - 5 . In order to provide that data to wireless communication device  104 - 5 , wireless communication device  102  may encapsulate it within a packet  406  and transmit the packet  406  to wireless communication device  104 - 5 . In various embodiments, packet  406  may comprise a physical layer convergence protocol (PLCP) protocol data unit (PPDU). In some embodiments, packet  406  may comprise a data field  410  that contains the data to be provided to wireless communication device  104 - 5 . 
     In operating environment  400 , devices in wireless network  103  may wirelessly communicate in accordance with a protocol that defines various different data transmission procedures, each of which may correspond to a different scheme for transmitting a packet via channel(s) defined by a channelization scheme such as channelization scheme  200  of  FIG. 2  or channelization scheme  300  of  FIG. 3 . According to any given one of such data transmission procedures, one or more 2.16 GHz base channels may be used to convey a data field of a transmitted packet, and may be referred to as the data transmission channel(s) with respect to transmission of that packet. In various embodiments, the data transmission procedures defined by the protocol may include a base channel data transmission procedure, a wide channel data transmission procedure, and an aggregated carrier data transmission procedure. Transmission of a packet according to the base channel data transmission procedure may alternatively be referred to as transmission of that packet in “base channel mode.” Likewise, packet transmission according to the wide channel data transmission procedure may alternatively be referred to as packet transmission in “wide channel mode,” and packet transmission according to the aggregated carrier data transmission procedure may alternatively be referred to as transmission of that packet in “aggregated carrier mode.” 
     In some embodiments, transmission of a packet in base channel mode may involve transmitting a data field of that packet using a single data transmission channel. For example, if wireless network  103  implements channelization scheme  200  of  FIG. 2  and wireless communication device  102  transmits packet  406  in base channel mode, then it may transmit data field  410  via a single data transmission channel comprising one of base channels 1, 2, 3, 4, 5, and 6. The embodiments are not limited to this example. 
     In various embodiments, transmission of a packet in wide channel mode may involve transmitting a data field of that packet via a wide channel corresponding to a bonded set of two or more 2.16 GHz base channels. In this context, the two or more 2.16 GHz base channels being bonded would constitute the data transmission channels with respect to transmission of the packet. For example, if wireless network  103  implements channelization scheme  300  of  FIG. 3 , and wireless communication device  102  transmits packet  406  in wide channel mode using 2.16 GHz base channels 5, 6, 7, and 8 as data transmission channels, then it may transmit data field  410  via 8.64 GHz channel 29. The embodiments are not limited to this example. 
     In some embodiments, transmission of a packet in aggregated carrier mode may involve conveying a data field of that packet via an aggregated set of two or more 2.16 GHz base channels. In this context, the two or more 2.16 GHz base channels being aggregated would constitute the data transmission channels with respect to transmission of the packet. Unlike transmission in wide channel mode, which may involve performing a single modulation across the combined bandwidth of multiple data transmission channels (“the bonded channel set”), transmission in aggregated carrier mode may involve separate parallel modulations of each of multiple data transmission channels (“the aggregated channel set”). Transmission of a packet in aggregated carrier mode using two data transmission channels may also be referred to as transmission of that packet in “2.16 GHz+2.16 GHz” mode. In an example of an embodiment involving transmission in aggregated carrier mode (and more particularly, 2.16 GHz+2.16 GHz mode), wireless network  103  may implement channelization scheme  300  of  FIG. 3 , and wireless communication device  102  may perform separate modulations of 2.16 GHz base channels 5 and 7 in parallel in order to convey data field  410 . In the context of this example, 2.16 GHz base channels 5 and 7 would constitute the data transmission channels with respect to transmission of packet  406 . The embodiments are not limited to this example. 
     In various embodiments, in preparation for transmission of packet  406  to wireless communication device  104 - 5 , wireless communication device  102  may be operative to determine a channel usage configuration that is to be applied for transmission of packet  406 . In some embodiments, the applicable channel usage configuration for transmission of packet  406  may designate an amount of bandwidth that is to be occupied in conjunction with transmission of packet  406 . In the context of that transmission, the designated amount of bandwidth may be referred to as the “occupied bandwidth.” In various embodiments, the applicable channel usage configuration may specify a data transmission procedure according to which packet  406  is to be transmitted. In some embodiments, the applicable channel usage configuration may designate one or more 2.16 GHz base channels that are to serve as data transmission channels in the context of the transmission of packet  406  in the specified data transmission mode. 
     In various embodiments, the applicable channel usage configuration may also designate a particular 2.16 GHz base channel as a primary channel in the context of the transmission of packet  406 . In some embodiments, devices in wireless network  103  may communicate according to a protocol that requires that the primary channel be a base channel that corresponds to a portion of wireless spectrum that is modulated in conjunction with transmission of data field  410 —in other words, that the primary channel also serve as a data transmission channel. A primary channel of this type may be referred to as an “in-band” primary channel. In embodiments in which only in-band primary channels are permitted, the applicable channel usage configuration may designate a particular data transmission channel as the primary channel. In various other embodiments, a protocol governing communications between devices in wireless network  103  may permit the primary channel to correspond to a portion of wireless spectrum that is not modulated in conjunction with transmission of data field  410 . A primary channel of this type may be referred to as an “out-of-band” primary channel. In embodiments in which both in-band and out-of-band primary channels are permitted, the primary channel designated by the applicable channel usage configuration may or may not be a data transmission channel. The embodiments are not limited in this context. 
     In operating environment  400 , in order to successfully receive packet  406  and obtain the data comprised in data field  410 , wireless communication device  104 - 5  may require knowledge of various aspects of the channel usage configuration, such as the applicable data transmission mode, the identities of the primary channel and data transmission channel(s), and the occupied bandwidth. In some embodiments, a wireless communication protocol implemented in wireless network  103  may define a notification mechanism via which devices in wireless network  103  may be informed of such parameters. In order to optimize wireless communication performance within wireless network  103 , it may be desirable that the notification mechanism be designed such that it makes this information available to devices in wireless network  103  at a relatively low cost in terms of added overhead. 
     Disclosed herein are parameter encoding techniques that may be implemented in various embodiments in order to enable devices such as wireless communication device  102  to notify other devices of channel usage configuration parameters in a manner involving relatively little overhead. According to some such techniques, a wireless communication network such as wireless communication network  103  may implement a wireless communication protocol that defines a notification mechanism according to which a wireless communication device such as wireless communication device  102  may use information elements such as index values and/or bitmaps to specify channel usage configuration parameters associated with its transmissions. In various embodiments, the wireless communication device may include such information elements in PHY headers of transmitted packets in order to notify receiving devices of channel usage configuration parameters associated with those packets. The embodiments are not limited in this context. 
       FIG. 5  illustrates an example of an operating environment  500  that may be representative of the implementation of one or more of the disclosed parameter encoding techniques according to various embodiments. In operating environment  500 , a wireless network  503  may implement a protocol that defines a notification mechanism according to which transmitting devices inform other devices of channel usage configuration parameters associated with transmitted packets by including configuration information within PHY headers of those packets. Using one or more wireless communication channels of wireless network  503 , a wireless communication device  502  may wirelessly communicate with a wireless communication device  504 . 
     In various embodiments, wireless network  503  may comprise a wireless network that utilizes wireless channel frequencies of the 60 GHz band. In some embodiments, wireless communication devices  502  and  504  may be operative to wirelessly communicate with each other according to one or more standards for 60 GHz wireless communications. In various embodiments, wireless communication devices  502  and  504  may be operative to wirelessly communicate with each other according to one or more protocols and/or procedures defined in IEEE 802.11ad-2012, and/or predecessors, revisions, progeny, and/or variants thereof. In some embodiments, wireless communication devices  502  and  504  may be operative to wirelessly communicate with each other according to one or more protocols and/or procedures defined in one or more standards developed by IEEE 802.11 Task Group ay (TGay). In some embodiments, wireless communication devices  502  and  504  may comprise 60 GHz-capable STAs, such as DMG STAs or EDMG STAs. In various embodiments, wireless communication device  502  may operate as a PCP/AP, and wireless communication device  504  may operate as a non-PCP/AP STA. In various other embodiments, wireless communication device  504  may operate as a PCP/AP, and wireless communication device  502  may operate as a non-PCP/AP STA. In yet other embodiments, wireless communication devices  502  and  504  may both operate as non-PCP/AP STAs. The embodiments are not limited in this context. 
     In operating environment  500 , having identified data to be provided to wireless communication device  504 , wireless communication device  502  include that data in a data field  510  of a packet  506  that it transmits to wireless communication device  504 . Wireless communication device  502  may notify wireless communication device  504  of various channel usage configuration parameters applicable to transmission of packet  506  by including configuration information  509  in a PHY header  508  of packet  506 . Based on configuration information  509 , wireless communication device  504  may identify the applicable channel usage configuration, enabling it to successfully receive packet  506  and obtain the data contained in data field  510 . 
       FIG. 6  illustrates an example of an operating environment  600  that may be representative of the implementation of one or more of the disclosed parameter encoding techniques according to various embodiments. More particularly, operating environment  600  may be representative of various embodiments in which configuration information  509  of  FIG. 5  is provided in the form of a single index value  614 . In some embodiments, index value  614  may uniquely identify a particular combination of channel usage configuration parameters. In various embodiments, for example, index value  614  may uniquely identify a particular combination of occupied bandwidth, data transmission mode (such as base channel mode, wide channel mode, or aggregated carrier mode), primary channel, and data transmission channel(s). In some embodiments, index value  614  may be comprised in a field  612 , which may comprise a size (in bits) enabling the conveyance of each of a number of unique values that is at least as large as a number of different permissible combinations of channel usage configuration parameters. 
     In various embodiments, devices in wireless network  503  may communicate according to a protocol that implements channelization scheme  200  of  FIG. 2  and permits out-of-band (OOB) primary channels. In such embodiments, if overlap between wide channels is not permitted, there may be a total of 104 possible combinations (listed in Table 5) of occupied bandwidth, data transmission channel(s), and primary channel. In order to accommodate this number of possible combinations, field  612  may comprise a length of at least 7 bits. It is worthy of note that in embodiments in which overlap between wide channels is permitted, there may be a greater number of possible combinations, potentially necessitating that field  612  comprise more than 7 bits. The embodiments are not limited in this context.

     In some embodiments, devices in wireless network  503  may communicate according to a protocol that implements channelization scheme  300  of  FIG. 3  and permits out-of-band (OOB) primary channels. In such embodiments, if overlap between wide channels is not permitted, there may be a total of 168 possible combinations (listed in Table 6) of occupied bandwidth, data transmission channel(s), and primary channel. In order to accommodate this number of possible combinations, field  612  may comprise a length of at least 8 bits. It is worthy of note that in embodiments in which overlap between wide channels is permitted, there may be a greater number of possible combinations, potentially necessitating that field  612  comprise more than 8 bits. The embodiments are not limited in this context.

     In some embodiments, wireless communication device  502  may generally be operative to identify index value  614  based on a mapping scheme according to which respective index values are mapped to various possible channel usage configurations. In some embodiments, in order to enable application of such a mapping scheme, wireless communication device  502  may be operative to determine a primary channel identifier (ID)  616  and one or more data transmission channel ID(s)  618 . Primary channel ID  616  may comprise a channel ID associated with the primary channel designated by the applicable channel usage configuration. Data transmission channel ID(s)  618  may comprise one or more channel IDs, each one of which may comprise a channel ID associated with a respective one of the one or more data transmission channels designated by the applicable channel usage configuration. 
     In various embodiments, wireless communication device  502  may apply a mapping scheme to identify index value  614  based on primary channel ID  616  and transmission channel ID(s)  618 . In some such embodiments, wireless communication device  502  may determine an offset value  620  based on the occupied bandwidth and the data transmission mode, and may identify index value  614  based on primary channel ID  616 , transmission channel ID(s)  618 , and offset value  620 . The embodiments are not limited in this context. 
     In various embodiments, wireless communication device  504  may identify the index value  614  comprised in field  612 , and may then identify a channel usage configuration that corresponds to that index value  614 . In some embodiments, wireless communication device  504  may then apply the identified channel usage configuration for reception of data field  510 . In various embodiments, based on index value  614 , wireless communication device  504  may determine primary channel ID  616  and data transmission channel ID(s)  618 . In some embodiments, based on index value  614 , wireless communication device  504  may identify an occupied bandwidth and/or a data transmission mode associated with transmission of packet  506 . The embodiments are not limited in this context. 
       FIG. 7  illustrates an example of an operating environment  700  that may be representative of the implementation of one or more of the disclosed parameter encoding techniques according to various embodiments. More particularly, operating environment  700  may be representative of various embodiments in which two fields are used to provide wireless communication device  504  with configuration information for use in identifying the applicable channel usage configuration for packet  506 . In operating environment  700 , wireless communication device  502  may include configuration information  709 A in a field  712 A of PHY header  508 , and may include configuration information  709 B in a field  712 B of PHY header  508 . In some embodiments, configuration information  709 A may comprise information identifying the data transmission channel(s) with respect to transmission of packet  506 , and configuration information  709 B may comprise information identifying the primary channel for that transmission. In various embodiments, configuration information  709 B may comprise a three-bit value indicating a 2.16 GHz base channel that comprises the primary channel. The embodiments are not limited in this context. 
     In some embodiments, configuration information  709 A may take the form of an index value of a similar nature as index value  614 . In various such embodiments, the use of separate field  712 B to convey configuration information  709 B indicating the identity of the primary channel may reduce the number of different possible index values that need to be accommodated by field  712 A (relative to field  612  in operating environment  600  of  FIG. 6 ). For example, if devices in wireless network  503  communicate according to a protocol that implements channelization scheme  200  of  FIG. 2  and wide channel overlap is not permitted, then field  712 A may only need to accommodate 27 different possible index values instead of  104 , and may thus be implemented using only 5 bits instead of 7. Similarly, if devices in wireless network  503  communicate according to a protocol that implements channelization scheme  300  of  FIG. 3  and wide channel overlap is not permitted, then field  712 B may only need to accommodate 44 different possible index values instead of 168, and may thus be implemented using only 6 bits instead of 8. The embodiments are not limited to these examples. 
     In some embodiments, rather than comprising an index value, the configuration information  709 A in field  712 A may comprise a bitmap. In various embodiments, each bit of the bitmap may be set to indicate whether a respective 2.16 GHz base channel constitutes a data transmission channel with respect to transmission of packet  506 . In some embodiments, field  712 A may contain a 6-bit bitmap, each bit of which may correspond to a respective one of 2.16 GHz base channels 1-6 of channelization scheme  200  of  FIG. 2 . In various embodiments, field  712 A may contain an 8-bit bitmap, each bit of which may correspond to a respective one of 2.16 GHz base channels 1-8 of channelization scheme  300  of  FIG. 3 . In some embodiments, PHY header  508  may include a bit set to indicate whether packet  506  is being transmitted in aggregated carrier mode. In various embodiments, in the event that a bitmap in field  712 A indicates the use of multiple contiguous 2.16 GHz base channels, the inclusion of such a bit may enable wireless communication device  504  to determine whether those contiguous channels are being bonded or aggregated in conjunction with transmission of packet  506 . The embodiments are not limited in this context. 
     Operations for the above embodiments may be further described with reference to the following figures and accompanying examples. Some of the figures may include a logic flow.

For example, in operating environment  700  of  FIG. 7 , wireless communication device  502  may determine a channel usage configuration that is to be applied for transmission of packet  506  to wireless communication device  504 . At  804 , a PHY header of the packet may be generated, and the PHY header may comprise a first field indicating one or more data transmission channels and a second field indicating a primary channel. For example, in operating environment  700  of  FIG. 7 , wireless communication device  502  may generate PHY header  508 , which may comprise a field  712 A containing configuration information  709 A indicating one or more data transmission channels, and a field  712 B containing configuration information  709 B indicating a primary channel. At  806 , the PHY header may be encoded for wireless transmission. For example, in operating environment  700  of  FIG. 7 , wireless communication device  502  may encode PHY header  508  for wireless transmission to wireless communication device  504 . The embodiments are not limited to these examples. 
       FIG. 9  illustrates an example of a logic flow  900  that may be representative of operations that may be performed according to one or more of the disclosed parameter encoding techniques in various embodiments.

As shown in  FIG. 9 , a PHY header for a packet to be received from a remote device may be decoded at  902 . For example, in operating environment  700  of  FIG. 7 , wireless communication device  504  may decode the PHY header  508  of packet  506 . At  904 , a primary channel may be identified based on a field comprised in the PHY header. For example, in operating environment  700  of  FIG. 7 , wireless communication device  504  may identify the primary channel based on configuration information  709 B comprised in field  712 B of PHY header  508 . At  906 , one or more data transmission channels may be identified based on a field comprised in the PHY header. For example, in operating environment  700  of  FIG. 7 , wireless communication device  504  may identify one or more data transmission channels based on configuration information  709 A comprised in field  712 A of PHY header  508 . At  908 , a data field of the packet may be received via the one or more data transmission channels. For example, in operating environment  700  of  FIG. 7 , wireless communication device  504  may receive data field  510  via one or more data transmission channels identified based on configuration information  709 A comprised in field  712 A of PHY header  508 . The embodiments are not limited to these examples.

     Numerous specific details have been set forth herein to provide a thorough understanding of the embodiments. It will be understood by those skilled in the art, however, that the embodiments may be practiced without these specific details. In other instances, well-known operations, components, and circuits have not been described in detail so as not to obscure the embodiments. It can be appreciated that the specific structural and functional details disclosed herein may be representative and do not necessarily limit the scope of the embodiments. 
     Some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. These terms are not intended as synonyms for each other. For example, some embodiments may be described using the terms “connected” and/or “coupled” to indicate that two or more elements are in direct physical or electrical contact with each other. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other. 
     Unless specifically stated otherwise, it may be appreciated that terms such as “processing,” “computing,” “calculating,” “determining,” or the like, refer to the action and/or processes of a computer or computing system, or similar electronic computing device, that manipulates and/or transforms data represented as physical quantities (e.g., electronic) within the computing system&#39;s registers and/or memories into other data similarly represented as physical quantities within the computing system&#39;s memories, registers or other such information storage, transmission or display devices. The embodiments are not limited in this context. 
     It should be noted that the methods described herein do not have to be executed in the order described, or in any particular order. Moreover, various activities described with respect to the methods identified herein can be executed in serial or parallel fashion. 
     Although specific embodiments have been illustrated and described herein, it should be appreciated that any arrangement calculated to achieve the same purpose may be substituted for the specific embodiments shown. This disclosure is intended to cover any and all adaptations or variations of various embodiments. It is to be understood that the above description has been made in an illustrative fashion, and not a restrictive one. Combinations of the above embodiments, and other embodiments not specifically described herein will be apparent to those of skill in the art upon reviewing the above description. Thus, the scope of various embodiments includes any other applications in which the above compositions, structures, and methods are used. 
     It is emphasized that the Abstract of the Disclosure is provided to comply with 37 C.F.R. § 1.72(b), requiring an abstract that will allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate preferred embodiment. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein,” respectively. Moreover, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects. 
     Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
