     BACKGROUND OF THE INVENTION 
     I. Technical Field 
     The invention relates generally to eyewear devices, and more particularly to apparatuses, methods, and systems for providing information to a user through a modularized eyewear device. 
     2. Background 
     The pace of modern life moves at a fast past. A person is often placed under the constraint of time and is placed in situations where his or her hands are occupied and information is not accessible to the person. This can present a problem. Currently available eyewear such as prescription glasses, e.g., prescription reading glasses or prescription sunglasses are expensive and are not readily reconfigured to different user&#39;s needs. This can present a problem. Personalized sound transmission is often done with an occlusive in ear device known as an earphone or earbud. Such a device obstructs the ear canal and can interfere with a user&#39;s hearing of far field sounds. This can present a problem. Thus, problems exist that requires technical solutions that uses technical means to produce technical effects.

     DETAILED DESCRIPTION 
     In the following detailed description of embodiments of the invention, reference is made to the accompanying drawings, in which like references indicate similar elements, and in which is shown by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those of skill in the art to practice the invention. In other instances, well-known circuits, structures, and techniques have not been shown in detail in order not to obscure the understanding of this description. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the invention is defined only by the appended claims. 
     In one or more embodiments, methods, apparatuses, and systems are described, that provide modularization of an eyewear system for a user. As described in the description of embodiments below, various combinations and configurations of electronics are taught for incorporation into eyewear devices. Some electronics configurations are removably couplable to an eyewear device. In some embodiments, an electronics configuration is built-into an eyewear device. In yet other embodiments, a behind the neck module assembly is releasably couplable with an eyewear device. In various embodiments, the modularized reconfigurable eyewear devices provide information to a user through the eyewear device. As used in this description of embodiments, information includes streaming audio in the form of music, information also includes parameters of a user&#39;s biology (e.g., biometrics of physiology, biomechanics, etc.) such as, but not limited to; heart rate, breathing rate, posture, steps, cadence, etc. Information also includes information of interest to a user such as, but not limited to; information on a vehicle that a user is using such as; revolutions per minute (RPM) of a bicycle, engine parameters such as RPM, oil pressure, cooling water temperature, wind speed, depth of water, air speed, etc. In various embodiments, information is presented to a user through an eyewear device by, for example, an audio broadcast that a user hears and a video broadcast to a display that the user sees in the eyewear device, or sees as an image as projected onto a pupil of the user&#39;s eye. Thus, information is to be given an expansive meaning within the scope of embodiments taught herein. 
       FIG. 1  illustrates a modular reconfigurable eyewear system, according to embodiments of the invention. With reference to  FIG. 1 , a modularized eyewear device is shown in perspective view at  100 . The modularized eyewear device  100  has a frame chassis  102 . In various embodiments, the frame chassis  102  is ophthalmically constructed to provide frame rim portions that hold lens  120  and lens  122 . The lens  120  and  122  can provide any of the functions that eyewear devices provide, such as but not limited to, a safety glass lens, a prescriptive lens, a sunglass lens, a welding glass lens, etc. An eyewear device can also contain a single lens instead of the dual lens illustrated. In some embodiments, a nose pad is provided, thereby providing a cushion for the contact zone with a user&#39;s nose. In some embodiments, the nose pad is made from a compliant material such as silicon rubber. 
     A temple  104  (left temple) and a temple  114  (right temple) are coupled to the frame chassis  102 . The temples  104  and  114  can be flexibly coupled to the frame chassis  102 , with hinges as shown in the figure or the temples  104  and  114  can be provided with a fixed orientation relative to the frame chassis  102 . 
     In various embodiments, one or more temples ( 104  and  114 ) and the chassis frame  102  can be fitted with electronics as described below. Within the view of  100 , a left temple insert module (TIM)  106  is configured with the left temple  104  and a right temple insert module (TIM)  116  is configured with the right temple  114 . Temple insert modules (TIMs) are described more fully in conjunction with the figures below. 
     With continued reference to  FIG. 1 , a modularized eyewear device is shown in exploded view at  130 . A frame chassis  132  is ophthalmically constructed to encircle a lens  140  and a lens  142  with a frame rim thereby securing the lens  140  and the lens  142  thereto. A brow bar  146  is fastened to the frame chassis  132  in various ways, via assembly fasteners, adhesive, etc. A left temple  144  includes a left temple connector  152  which is rotatably coupleable with a left chassis connector  150 . Together, the left chassis connector  150  and the left temple connector  152  form a rotatable mechanical and electrical connection between the chassis  132  and the left temple  144 , thereby providing one or more electrical pathways to connect the frame chassis  132  to the left temple  144 . Similarly, a right temple  134  is rotatably coupleable to the frame chassis  132  through a right hinge assembly  148 . 
     Note that in some embodiments, a modularized eyewear device is configured such that each temple can be removed from its hinge via an electrical/mechanical connector having one or more electrical contacts, not shown for clarity in the illustration. These electrical contact points can be made using, for example, pins, points, pads, slots, contact devices, etc. For example, the line indicated at  154  demarcates the mating of the right temple connector with the right temple  134 . Similarly, the line indicated at  156  demarcates the mating of the left temple connector  152  with the left temple  144 . 
     Through the provision of electrical/mechanical connectors between each temple, e.g.,  134 ,  144  and the frame chassis  132  the temples are interchangeable with the eyewear device. This functionality permits a user to interchange one temple with another. Different temples can be configured with different electronics to provide different functionality as described herein. Either temple can be configured to accommodate various electronics configurations. For example, in one or more embodiments, the right interchangeable temple accommodates an electronics package that can include one or more of; a biometric sensor, a biomechanical sensor, a vehicle sensor, an environmental sensor, a temperature sensor, an acoustic sensor, a motion sensor, a light sensor, a touch sensor, a proximity sensor, a velocity sensor, an acceleration sensor, a rotation sensor, a magnetic field sensor, a global position system (GPS) receiver, cables, microphones, a micro speaker, a source of electrical power (battery), a camera, a micro display, a heads-up display (HUD) module, a multiaxis inertial measurement unit, a wireless communications system. Note that a TIM can also contain the electronics package and sensor(s) described above. In various embodiments, one or more wireless communication system are provided that utilize for example; near-field communications (NFC) using the industrial-scientific-medical (ISM) frequency of 13.56 MHz, the Adaptive Network Topology (ANT) ANT+ wireless standard, wireless communications using a Bluetooth standard, a Bluetooth low energy standard (BLE), wireless communication using a Wi-Fi standard, and wireless communication using mobile telephone standards such as for example the 3G, 4G, Long Term Evolution (LTE), 5G, etc. standard or other wireless standards. In some embodiments, electrical pathways from the electronics exit a temple via a sheath cavity and travel into a temple sheath and continue into a brow bar sheath cavity. The right interchangeable temple contains a hinge-connector  148  that fastens to the brow bar  146  and chassis frame  132 . 
     In one or more embodiments, the right interchangeable temple attaches to the front of the frame chassis via a hinge-connector that allows for power and data transferred to the left interchangeable temple through the modular brow bar. The hinge-connector mechanically interlocks with the frame chassis and allows for power/data connectivity with electrical pin conductors. In one or more embodiments, when positioned in the open direction of wearing, the hinge-connectors sense the open state of the device allowing for power or data transfer. When in the closed position (temples folded inward), the hinge-connector in conjunction with signals received from one or more of proximity sensors and motion sensors will allow the system to sense the user-device interaction state and will deactivate the power or data transfer. This function leads to reduced power consumption when folded and stowed and can lead to automatic power up while a user wears the device on his or her head. In addition to switchable data or power transfer from the hinge-connector, the hinge-connector can provide flexible circuits and wired micro-connectors that provide steady uninterrupted power and or data transfer. 
     In some embodiments, it is convenient to route electrical pathways within a volume of the brow bar  146 . In some embodiments, the brow bar  146  is constructed to provide a channel along its length, within which the electrical pathways are routed. Thus, the brow bar  146  provides one or more sheaths, channels, etc. along its length within which electrical pathways and sensors can be contained. Examples of electrical pathways are, but are not limited to; wires, printed circuit board, flexible printed circuit board, etc. In various embodiments, it is advantageous to mount one or more sensors to the brow bar  146 , thereby making an electrical sub-assembly for the frame chassis  132 . In some embodiments, additional electrical pathways from the frame chassis  132  are joined with the electrical pathway contained in the brow bar  146 . In some embodiments, a flexible electronic circuit is adhered to the underside top face of the brow bar and exits the brow bar via the left and right sheath cavities. Alternatively, or in combination, fully embedded flexible electronics may be cast into the brow bar with integrated contact points exiting the brow bar near each hinge. These integrated contact points on both sides of the brow bar allow transmission of data or power when in contact with the integrated contact points of the right and left temple. In addition to facilitating connection to electronics, the brow bar can conceal an optional pupil module by a securing flange and allows the user to view a microdisplay via the brow bar pupil aperture. 
     In similar fashion the left temple is configured as a left interchangeable temple connected to the front frame of the eyewear with a left hinge-connector. In various embodiments, the left interchangeable temple can contain the same electronics configuration/functionality as the right interchangeable temple or interchangeable temples can contain different electronics configurations and different functionality. 
     With continued reference to  FIG. 1 , a left temple  164  and right temple  174  are configured as shown at  160 . Each of the temples  164  and  174  contain electronics which are configured to provide information and functionality to a user of the eyewear system. As shown at  160 , the left temple  164  has a temple door (not shown) removed thereby exposing an electronics package indicated at  186 . The temple door secures and protects electronics from environmental exposure and hazard. The temple door is secured to the temple assembly with suitable mechanical fasteners for a given application. In some embodiments, the temple door provides a rating with respect to water intrusion via an IP Code from International Protection Marking IEC standard 60529. A source of electrical power (battery) is illustrated at  184  and an audio speaker and port is illustrated at  182 . The audio speaker and port  182  is generally located on a posterior end of a temple and in some embodiments is an integrated directional projection speaker that privately directs sound to a user&#39;s ear. Projection stereo speakers can communicate various audio signals to the user, such as but not limited to, voice prompts, streaming music, smart audio assistance, data, etc. Notably, the projection speaker design does not occlude the user&#39;s ear. Thus, the user can hear far field sounds and the far field sounds are not degraded as they are with currently available earbud style headphones that occlude a user&#39;s ear. 
     The right temple  174  is also provided with an electronics package (not shown in the view) contained within the right temple  174 . The right temple is provided with an audio speaker with audio speaker port  184 , which can be an integrated directional projection speaker. In one or more embodiments, the right temple  174  is configured to accommodate an external assembly  190  that contains a micro display assembly  192 . Similarly, the left temple could be configured for the external assembly  190  and the micro display assembly  192 . 
     In various embodiments, a micro display assembly, such as  192 , is a head up display (HUD) Pupil™ Optics Module that houses the optics, electronics, and micro display that form the optical system. The pupil mechanism also may house cables, flexible circuit boards, or wires which exit from a housing into an electronics contact pathway. In one or more embodiments, these electrical pathways are connected to a side of the left temple  174  to enable the user with a see-through head up display external accessory to enhance a visual component of a mobile reality experience. 
     In one or more embodiments, wiring which exits the brow bar is concealed in the right and left sheaths of the temples and enters into the right and left temples via the sheath cavities, thereby protecting the wiring from environmental hazards. The area near the contact pathway may also accommodate motion mechanisms for customizing the interpupillary distance of the head-up micro display module. 
     In different embodiments, the front frame portion, such as  102  or  132  ( FIG. 1 ) or any similar structure in the figures below, and the right and left temple portions, such as  104 ,  114 ,  134 ,  144 ,  164 ,  174  ( FIG. 1 ) or any similar structures in the figures below, can be part of a set of interchangeable front frame portions and temple portions each having the same or different combinations of devices, accessories, capabilities and/or functions. At least one of an electronics board, microphones, speakers, battery, camera, heads-up display module, wireless Wi-Fi radio, GPS chipset, LTE cellular radio, multiaxis inertial measurement unit, motion sensor, touch sensor, light and proximity sensors, etc. can be included in desired combinations. Electronics can be further included that permit a user to perform at least one of; wirelessly connecting to a cellular service, a smart phone, a smart watch, a smart bracelet, a mobile computer, and a sensor peripheral. The electronics can further include the ability to; view see-through augmented reality images via a modular head up display (HUD), provide stereo audio content, provide voice and audio notification including music through one or more integrated projection micro-speakers. The front frame electrical contact devices and the temple electrical contact devices can include electrical contact points in or near respective hinge connectors for removable electrical contact with each other for electrically transmitting at least one of; power, electrical signals and data between the temple portions and the front frame portion when the contact points are in an electrically closed position. In some embodiments when assembled together, the front frame hinge connectors, the front frame electrical contact devices, the temple hinge connectors and the temple electrical contact devices can form electromechanical hinges, hinge connectors, assemblies or devices. In some embodiments, system electrical power can be turned off by folding the temple portions into a storage position thereby disconnecting the contact points. 
     In some embodiments, at least one of the front frame electronics and the temple electronics can include at least one of a battery, camera, heads-up display module, controller, digital storage electronics, CPU, projection micro-speaker, microphone, wireless Wi-Fi radio, GPS chipset, LTE cellular radio, multiaxis inertial measurement system or unit, and sensory, motion, touch, light, proximity, temperature and pressure sensors, etc. 
     In some embodiments, at least one temple can include a temple module insert (TIM) containing selected temple electronics, mounted thereto. In other embodiments, a neck smart cord is electrically connected to a behind the neck electronics module. The neck smart cord has right and left connectors or connector ends for mechanically and or electrically interconnecting the behind the neck electronics module with the right and left temples of an eyewear device. 
       FIG. 2  illustrates a reconfigurable component for an eyewear device, according to embodiments of the invention. With reference to  FIG. 2  at  200 , a temple  202  is provided with an engagement portion  204 . A temple insert module, referred to in this description of embodiments as a “TIM” at  210  is configured to be releasably coupleable with the engagement portion  204  of the temple  202 . The TIM  210  is installed into the temple  202  as indicated by arrows  212   a  and  212   b . In various embodiments, the engagement portion  204  is accomplished by a mechanical connection, such as but not limited to; press fit, clip, mechanical interlock, hook and loop, magnetic surface, external clamp to temple, flange and mechanical coupling to temple, etc. In yet other embodiments the engagement portion  204  and the TIM  210  utilize magnetic surfaces, thereby holding the TIM  210  secure by magnetic attraction. The form of the engagement portion shown at  204 , as well as the form of any engagement portion illustrated elsewhere in the figures presented herein, is given merely for illustration and does not limit embodiments of the invention. In the view illustrated at  200 , the TIM  210  only makes a mechanical connection with the temple  202  no electrical connection is provided between the TIM  210  and the temple  202 . 
     In some embodiments, the TIM  210  is provided with a speaker and speaker port  214 , which can be a micro projection speaker. The speaker provides information to a user through an audio broadcast. Note that the speakers provided herein are speakers that are located externally from a user&#39;s ear and are therefore not inserted into the user&#39;s ear like an earbud is inserted. The TIM  210  is configured with an electronics package that contains a processor, memory, electrical power, and one or more wireless communication protocols that enable the TIM  210  to communicate wirelessly  222  with one or more devices  220 . The device  220  can be an external sensor such as, but not limited to; a biometric sensor or a vehicle sensor, a local user device, a network node, such as a wireless router, a remote network, or a remote user device such as a mobile phone accessed through a network. Different sensors, networks, and remote devices are described more fully in conjunction with the figures below. 
     Following the architecture of  FIG. 2  at  200 , in some embodiments, a second temple and a second TIM are provided. The two TIMs in such a system can engage in wireless communication between the device  220  and between themselves as needed to provide a level of design functionality to a user. For example, in one embodiment, a left TIM includes wireless network capability sufficient to communicate with the remote device  220 , utilizing a first network protocol. In addition, the left TIM and the right TIM are provided with wireless network capability that supports communication utilizing a second network protocol. In order to conserve electrical power, the first network protocol has a greater range than the second network protocol because a distance between the left TIM and the remote device is greater than a separation distance between the left TIM and the right TIM (nominally a width of user&#39;s head). The architecture illustrated at  200  is referred to as true wireless because there is no wired connection between the left TIM and the right TIM. In one or more embodiments, an audio stream is provided from a user device to a first TIM utilizing a first wireless network. Then a second wireless audio stream is provided from one TIM to the other TIM utilizing a second wireless network in order to provide the audio stream to each of a left and a right projection speakers of the eyewear device. 
     The temples and TIMs described at  200  provide reconfigurable components for eyewear devices as described in conjunction with the figures herein. A forward end  206  of the temple  202  is engageable with a frame chassis of an eyewear device as described above with or without a connector between a temple and a frame. Thus, the temple  202  can attain a fixed position relative to a frame chassis or the temple can be rotatably coupled to the frame chassis depending on a give design of the eyewear. 
     With reference to  FIG. 2  at  250 , a temple  252  is provided with an engagement portion  254 . A temple insert module, TIM at  260 , is configured to be releasably coupleable with the engagement portion  254  of the temple  252 . The TIM  260  is installed into the temple  252  as indicated by arrows  262   a  and  262   b . In various embodiments, the engagement portion  204  is accomplished by a combined electrical and mechanical connection. The mechanical connection can be as described in conjunction with  210 / 204  such as, but not limited to: press fit, clip, mechanical interlock, hook and loop, etc. In yet other embodiments the engagement portion  254  and the TIM  260  utilize magnetic surfaces, thereby holding the TIM  260  secure by magnetic attraction. A number of electrical contacts  280  are provided for illustration with no limitation implied thereby. The electrical contacts  280  mate with corresponding electrical contacts in the temple  252  thereby providing electrical connection to one or more electrical pathways (not shown) in the temple  252 . The electrical pathways within the temple  252  facilitate electrical connection between the TIM  260  and one or more sensors  272  and  274 , which can also represent a source of signals provided to a display(s). The sensors  272  and  274  can be acoustic sensors such as microphones or any of the sensors described herein for use in conjunction with electronics packages configured with eyewear devices. In one or more embodiments, one or more of  272  and  274  provide signals to a display such as a HUD. 
     In some embodiments, the TIM  260  is provided with a speaker and speaker port  264 , which can be a micro projection speaker. The speaker provides information to a user through an open-ear audio broadcast. 
     Following the architecture of  FIG. 2  at  250 , in some embodiments, a second temple and a second TIM are provided, as shown below in  FIG. 3 . The two TIMs in such a system engage in wireless communication between the device  220  and between themselves as needed to provide a level of design functionality to a user. The temples and TIMs described at  250  provide reconfigurable components for eyewear devices as described in conjunction with the figures herein. For example, a forward end  256  of the temple  252  is engageable with a frame chassis of an eyewear device as described above with or without a connector between a temple and a frame. Thus, the temple  252  can attain a fixed position relative to a frame chassis or the temple can be rotatably coupled to the frame chassis depending on a given design of the eyewear. 
       FIG. 3  illustrates, at  300 , multiple reconfigurable components for an eyewear device, according to embodiments of the invention. With reference to  FIG. 3  at  300 , the left reconfigurable component  250  from  FIG. 2  is illustrated with a companion right reconfigurable component for an eyewear device. A right temple  352  has an engagement portion that is not shown in  FIG. 3  but is similar to the engagement portion  254  of the left temple  252 . A temple insert module, TIM at  360  is configured to be releasably coupleable with the engagement portion of the temple  352 . The TIM  360  is couple with the temple  352  as indicated by arrows  362   a  and  362   b . In various embodiments, the engagement portion of the temple  352  is accomplished by a combined electrical and mechanical connection. The mechanical connection can be provided as described above in conjunction with  210 / 204  such as, but not limited to; press fit, clip, mechanical interlock, hook and loop, etc. In yet other embodiments the engagement portion of the temple  352  and the TIM  360  utilize magnetic surfaces, thereby holding the TIM  360  secure by magnetic attraction. Several electrical contacts  380  are provided for illustration with no limitation implied thereby. The electrical contacts  380  mate with corresponding electrical contacts in the temple  352  thereby providing electrical connection to one or more electrical pathways (not shown) in the temple  352 . The electrical pathways within the temple  352  facilitate electrical connection between the TIM  360  and one or more sensors  372  and  374 . The sensors  372  and  374  can be acoustic sensors such as microphones or any of the sensors or displays described herein for use in conjunction with electronics packages configured with eyewear devices. In various embodiments, the TIM  360  is configured with an electronics package that contains a processor, memory, electrical power, and one or more wireless communication systems using protocols that enable the TIM  360  to communicate wirelessly as indicated by a wireless transmission at  222  with one or more devices  220 . In addition, the TIM  360  and the TIM  260  can be configured with wireless communication capability that permits wireless communication between the TIMs as indicated by a wireless transmission at  382 . In some embodiments, the TIM  360  is provided with a speaker and a speaker port indicated at  364 , which can be a micro projection speaker. The speaker provides information to a user through an audio broadcast. 
     With reference to view  390  of  FIG. 3 , electrical connectivity schematics are illustrated for each of TIM  260  and TIM  360 . The TIM  260  is electrically coupled to the sensor  272  with an electrical pathway  394 . Similarly, the TIM  260  is electrically coupled to the sensor  274  by an electrical pathway  392 . The connectivity illustrated between the TIM  260  and the respective sensors constitutes a left temple electrical schematic  384 . Note that the left temple electrical schematic  384  can be more complex or less complex that the illustration. Thus, the left temple electrical schematic is provided merely for illustration with no limitation implied thereby. 
     Similarly, the TIM  360  is electrically coupled to the sensor  372  with an electrical pathway  398 . The TIM  260  is electrically coupled to the sensor  374  by an electrical pathway  396 . The connectivity illustrated between the TIM  360  and the respective sensors constitutes a right temple electrical schematic  386 . Note that the right temple electrical schematic  386  can be more complex or less complex that the illustration. Thus, the right electrical schematic is provided merely for illustration with no limitation implied thereby. 
     The two TIMs in such a system engage in wireless communication between the device  220  and between themselves as needed to provide a level of design functionality to a user. For example, in one embodiment, a left TIM includes wireless network capability sufficient to communicate with the remote device  220 , utilizing a first network protocol. In addition, the left TIM and the right TIM are provided with wireless network capability that supports wireless communication as indicated at  382 . The wireless communication  382  can be performed with a second network protocol, which is different from that used at  222 . In order to conserve electrical power, the first network protocol ( 222 ) has a greater range than the second network protocol ( 382 ) because a separation distance between the left TIM  260  and the remote device  220  is greater than a separation distance between the left TIM  260  and the right TIM  360 , the latter is nominally a width of user&#39;s head and the former can be as much as a distance to a mobile telephone cellular tower.

     For purposes of discussing and understanding the different embodiments, it is to be understood that various terms are used by those knowledgeable in the art to describe techniques and approaches. Furthermore, in the description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of an embodiment. It will be evident, however, to one of ordinary skill in the art that an embodiment may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring various embodiments. These embodiments are described in sufficient detail to enable those of ordinary skill in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, mechanical, electrical, and other changes may be made without departing from the scope of the present invention. 
     Some portions of the description may be presented in terms of algorithms and symbolic representations of operations on, for example, data bits within a computer memory. These algorithmic descriptions and representations are the means used by those of ordinary skill in the data processing arts to most effectively convey the substance of their work to others of ordinary skill in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of acts leading to a desired result. The acts are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. 
     It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, can refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system&#39;s registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission, or display devices. 
     An apparatus for performing the operations herein can implement the present invention. This apparatus may be specially constructed for the required purposes, or it may comprise a general-purpose computer, selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a computer readable storage medium, such as, but not limited to, any type of disk including floppy disks, hard disks, optical disks, compact disk-read only memories (CD-ROMs), and magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs), dynamic random access memories (DRAM), electrically programmable read-only memories (EPROM)s, electrically erasable programmable read-only memories (EEPROMs), FLASH memories, magnetic or optical cards, RAID, etc., or any type of media suitable for storing electronic instructions either local to the computer or remote to the computer. 
     The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general-purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the required method. For example, any of the methods according to the embodiments can be implemented in hard-wired circuitry, by programming a general-purpose processor, or by any combination of hardware and software. One of ordinary skill in the art will immediately appreciate that the embodiments can be practiced with computer system configurations other than those described, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, digital signal processing (DSP) devices, set top boxes, network PCs, minicomputers, mainframe computers, and the like. The embodiments can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. 
     The methods herein may be implemented using computer software. If written in a programming language conforming to a recognized standard, sequences of instructions designed to implement the methods can be compiled for execution on a variety of hardware platforms and for interface to a variety of operating systems. In addition, the embodiments are not described with reference to any particular programming language. It will be appreciated that a variety of programming languages may be used to implement the teachings of the embodiments as described herein. Furthermore, it is common in the art to speak of software, in one form or another (e.g., program, procedure, application, driver, . . . ), as taking an action or causing a result. Such expressions are merely a shorthand way of saying that execution of the software by a computer causes the processor of the computer to perform an action or produce a result. 
     It is to be understood that various terms and techniques are used by those knowledgeable in the art to describe communications, protocols, applications, implementations, mechanisms, etc. One such technique is the description of an implementation of a technique in terms of an algorithm or mathematical expression. That is, while the technique may be, for example, implemented as executing code on a computer, the expression of that technique may be more aptly and succinctly conveyed and communicated as a formula, algorithm, or mathematical expression. Thus, one of ordinary skill in the art would recognize a block denoting A+B=C as an additive function whose implementation in hardware and/or software would take two inputs (A and B) and produce a summation output (C). Thus, the use of formula, algorithm, or mathematical expression as descriptions is to be understood as having a physical representation in at least hardware and/or software (such as a computer system in which the techniques of the present invention may be practiced as well as implemented as an embodiment). 
     Non-transitory machine-readable media is understood to include any mechanism for storing information (such as program code, etc.) in a form readable by a machine (e.g., a computer). For example, a machine-readable medium, synonymously referred to as a computer-readable medium, includes read only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory devices; except electrical optical, acoustical or other forms of transmitting information via propagated signals (e.g., carrier waves, infrared signals, digital signals, etc.); etc. 
     As used in this description, “one embodiment” or “an embodiment” or similar phrases means that the feature(s) being described are included in at least one embodiment of the invention. References to “one embodiment” in this description do not necessarily refer to the same embodiment; however, neither are such embodiments mutually exclusive. Nor does “one embodiment” imply that there is but a single embodiment of the invention. For example, a feature, structure, act, etc. described in “one embodiment” may also be included in other embodiments. Thus, the invention may include a variety of combinations and/or integrations of the embodiments described herein. 
     While the invention has been described in terms of several embodiments, those of skill in the art will recognize that the invention is not limited to the embodiments described, but can be practiced with modification and alteration within the spirit and scope of the appended claims. The description is thus to be regarded as illustrative instead of limiting.
