Title: Identification of watch bands

Abstract:
A watch can include a watch body and a band for securing the watch to the user. The watch body can detect an identification of the band or combination of band portions, which can serve as an input to initiate actions performed by the watch body. For example, a type, model, color, size, or other characteristic of a band can be determined and used to select a corresponding action performed by the watch body. Identification of the band can be performed by components of the watch body that also serve other purposes. The watch body can respond to the identification of a particular band by performing particular functions, such as changing an aspect of a user interface or altering settings of the watch body.

     In one or more implementations, not all of the depicted components in each figure may be required, and one or more implementations may include additional components not shown in a figure. Variations in the arrangement and type of the components may be made without departing from the scope of the subject disclosure. Additional components, different components, or fewer components may be utilized within the scope of the subject disclosure. 
     DETAILED DESCRIPTION 
     The detailed description set forth below is intended as a description of various implementations and is not intended to represent the only implementations in which the subject technology may be practiced. As those skilled in the art would realize, the described implementations may be modified in various different ways, all without departing from the scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. 
     The following disclosure relates to identification of a band for use with an electronic device. The identification can serve as an input to initiate actions performed by the electronic device. For example, a type, model, color, size, or other characteristic of a band can be determined and used to select a corresponding action performed by the electronic device. 
     A watch can include a watch body and a band for securing the electronic device to the user. In many traditional devices, the electronic device does not interact with or even identify the band that is used in conjunction with the electronic device. In other devices, the band may provide certain functionality to supplement the functionality of the electronic device. However, such bands often require a power source, such as from an integrated battery or from the battery of the electronic device. Furthermore, such bands often require a robust communication link with the electronic device for bidirectional communication. These features impose significant design considerations that increase the cost and complexity of the parts. 
     In contrast to traditional devices, the band identification capabilities described herein provide simple and elegant solutions that allow an electronic device to readily identify a band. In some embodiments of the present disclosure, identification of the band can be achieved by a variety of mechanisms. For example, identification of the band can be performed by components of the electronic device that also serve other purposes. Existing sensors, communication elements, and/or detectors can be used to detect and identity a band provided to the electronic device. Accordingly, identification of a band with the electronic device can be achieved without adding dedicated components to the electronic device. Furthermore, identification can be achieved without sacrificing power to the band and without requiring a bidirectional communication link with the band. 
     A selection of a certain band can influence operation of the electronic device in a variety of ways. For example, the electronic device can respond to the identification of a particular band by performing particular functions, such as changing an aspect of a user interface or altering settings of the electronic device. Such functions can be readily executed by the electronic device upon identification of the band, such that user input is not required. Accordingly, a user&#39;s experience with the electronic device can be enhanced based on the user&#39;s selection of a particular band. 
     These and other embodiments are discussed below with reference to  FIGS.  1 - 15   . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. 
       FIG.  1    illustrates a perspective view of a watch  10 . The watch  10  can include a watch body  100  and a band  110 . As shown, the watch body  100  includes a housing  102  that supports a display  104 . The watch body  100  can be worn on a user&#39;s wrist and secured thereto by the band  110 . The band  110  includes lugs  112  at opposing ends of the band that fit within respective recesses or channels  114  of the housing  102  and allow the band  110  to be removably attached to the housing  102 . The lugs  112  may be part of the band  110  or may be separable (and/or separate) from the band  110 . Generally, the lugs  112  may lock into the channels  114  and thereby maintain connection between the band  110  and the housing  102 . The user may release a locking mechanism (not shown) to permit the lugs  112  to slide or otherwise move out of the channels  114 . In some watches, the channels  114  may be formed in the band  110  and the lugs may be affixed or incorporated into the housing  102 . While lugs  112  and channels  114  are illustrated, it will be recognized that other attachment elements, such as locks, snaps, clasps, threads, and pins can be included on the band  110  for securely attaching to the watch body  100 . 
     As shown in  FIG.  2   , the band  110  can include an identification element  190  that is detectable by one or more components of the watch body  100 . Features of the identification element  190  can be selected to achieve detection by the watch body  100 , as described further herein. For example, the identification element  190  can include a feature on a surface of the band  110  and/or be embedded within the structure of the band  110 . The identification element  190  can be positioned on or along any portion of the band  110  to facilitate detection. For example, the identification element  190  can be located near an end of the band  110  (e.g., at or near a lug  112 ). Alternatively or in combination, the identification element  190  can be located on a side of the watch  10  that is opposite the watch body  100 . The identification element  190  can be used to determine information about the band  110 , such as a type, characteristic, feature, or identity of the band  110 . Subsequent actions by the watch body  100  can correspond to the determined information. 
     As further shown in  FIG.  2   , the watch body  100  can include components that support the operations thereof. Such operations can include identification of a band  110 , actions based on the identification, and other operations that are independent of the identification. In some embodiments, components used for operations independent of the identification of the band  110  can also be used for identification. Such components are described below with reference to  FIG.  2   . 
     In some embodiments, as shown in  FIG.  2   , the watch body  100  includes a processor  150 , memory  152 , a power source  154 , and/or a charger  156  for providing power to the power source  154 . 
     The processor  150  can control or coordinate some or all of the operations of the watch body  100 . The processor  150  can communicate, either directly or indirectly with substantially all of the components of the watch body  100 . For example, a system bus or signal line or other communication mechanisms can provide communication between the processor  150 , the memory  152 , the power source  154 , as well as other components. The processor  150  can be implemented as any electronic device capable of processing, receiving, or transmitting data or instructions. As described herein, the term “processor” is meant to encompass a single processor or processing unit, multiple processors, multiple processing units, or other suitably configured computing element or elements. 
     The memory  152  can store electronic data that can be used by the watch body  100 . For example, a memory can store electrical data or content such as, for example, audio and video files, documents and applications, device settings and user preferences, timing and control signals or data for the haptic device  184 , data structures or databases, and so on. The memory  152  can be configured as any type of memory. By way of example only, the memory can be implemented as random access memory, read-only memory, Flash memory, removable memory, or other types of storage elements, or combinations of such devices. 
     A power source  154  can be implemented with any device capable of providing energy to the watch body  100 . For example, the power source  154  can be a battery and/or a connection cable that connects the charger  156  to another power source such as a wall outlet. In other examples, wireless power can be used. 
     In some embodiments, as shown in  FIG.  2   , the watch body  100  can include components for interacting with a user. In some embodiments, the watch body  100  includes a display  104 , a speaker  180 , a microphone  182 , and/or a haptic device  184 . 
     The display  104  may provide an image or video output for the watch body  100 . The display  104  may also provide an input surface for one or more input devices such as a touch sensing device, force sensing device, temperature sensing device, and/or a fingerprint sensor. The display  104  may be any size suitable for inclusion at least partially within the housing  102  of the watch body  100  and may be positioned substantially anywhere on the watch body  100 . Other input devices can be provided for operation by a user. For example, one or more buttons, dials, crowns, switches, or other devices can be provided for receiving input from a user. 
     The haptic device  184  can be implemented as any suitable device configured to provide force feedback, vibratory feedback, tactile sensations, and the like. For example, in one embodiment, the haptic device  184  may be implemented as a linear actuator configured to provide a punctuated haptic feedback, such as a tap or a knock. 
     In some embodiments, as shown in  FIG.  2   , the watch body  100  can include components that facilitate detection of an identification element  190 , among other functions. In some embodiments, the watch body  100  includes a sensor  124  (e.g., biometric sensors, environmental sensors, etc.), a communication element  160 , and/or a detector  170 . As used herein, “a sensor” can include or be operably connected to any component that is capable of facilitating detection of an identification element  190 . A sensor can include or be operably connected to the sensor  124 , the communication element  160 , and/or the detector  170 . As described herein, components of the watch body  100  can be used as sensors for detection of an identification element  190 , yet also have other functions apart from detection of the identification element  190 . 
     The watch body  100  can include a compass  122 . The compass  122  can include a magnetometer for detecting a presence and direction of a magnetic field. The compass  122  can be configured to detect a magnetic field of the Earth, and thereby provide information that can be used to determine the orientation of the watch body  100  with respect to magnetic poles of the Earth. The compass  122  can also be operated to detect magnetic fields from other sources, such as the identification element  190  of the band  110 , as discussed further herein. 
     The watch body  100  may also include one or more sensors  124  positioned substantially anywhere on the watch body  100 . The sensor or sensors  124  may be configured to sense substantially any type of characteristic such as, but not limited to, images, pressure, light, touch, force, temperature, position, motion, and so on. For example, the sensor(s)  124  may be a photodetector, a temperature sensor, a light or optical sensor, an atmospheric pressure sensor, a humidity sensor, a magnet, a gyroscope, an accelerometer, and so on. In other examples, the watch body  100  may include one or more health sensors. In some examples, the health sensors can be disposed on a bottom surface of the housing of the watch body  100 , as discussed further herein. Other sensors  124  or detectors  170  can be provided with similar or different functionality. 
     The communication element  160  can facilitate transmission of data to or from other electronic devices across standardized or proprietary protocols. For example, a communication element  160  can transmit electronic signals via a wireless and/or wired network connection. Examples of wireless and wired network connections include, but are not limited to, cellular, Wi-Fi, Bluetooth, infrared, RFID and Ethernet. The communication element  160  can communicate with or sense the band  110  or another device, as described further herein. 
     Referring now to  FIGS.  3 - 5   , the watch body  100  can detect an identification element  190  of a band  110  by operating one or more detectors  170 . As shown in  FIGS.  3 - 5   , a lug  112  can include an identification element  190 . The detector  170  of the watch body  100  can be located at or near the channel  114  into which the lug  112  is received. As shown in  FIGS.  4  and  5   , as the lug  112  is inserted into the channel  114 , the identification element  190  is brought into alignment with and close proximity to the detector  170 . While the identification element  190  is shown in  FIGS.  3 - 5    as being at the lug  112 , it will be recognized that the identification element  190  can be located at other positions. For example, the identification element  190  can be at any location at, on, or within the band  110 , including any distance away from the lug  112 . 
     In some embodiments, a detector  170  can be used to detect the identification element  190  before, during, and/or after the band  110  is attached to the watch body  100 . For example, the detector  170  can be operated to detect identification element  190  of the band  110  while the band is not connected to the watch body (e.g., with the lug  112  not inserted into the channel  114 ), as shown in  FIG.  3   . By further example, the detector  170  can be operated to detect identification element  190  of the band  110  while the band is being connected to the watch body (e.g., while the lug  112  is moving into the channel  114 ), as shown in  FIG.  4   . By further example, the detector  170  can be operated to detect identification element  190  of the band  110  after the band is connected to the watch body (e.g., with the lug  112  inserted into the channel  114 ), as shown in  FIG.  5   . 
     In some embodiments, the detector  170  can include one or more contact pins within the channel  114  for providing an electrically conductive pathway to the identification element  190 . Multiple pins can be provided to conduct power, provide a connection to ground, and transmit signals. The pins of the detector  170  can retract within the channel  114  to accommodate passage of the lug  112 . 
     In some embodiments, the detector  170  can optically sense the identification element  190  on the lug  112  or another portion of the band  110 . A light source can be provided to facilitate optical sensing by the detector  170 . For example, the detector can include or be accompanied by a light source that illuminates the identification element  190 , and the detector can optically detect the light reflected off of the identification element  190 , as discussed further herein. 
     For example, the band  110  can be positioned so that the identification element  190  is within a light path of a light source and within a field of view of the detector  170 . Light emitted from the light source can be reflected off of the identification element  190 . For example, the identification element  190  can include a pattern on the band  110  that reflects the wavelength(s) of light emitted from the light source. The light can be infrared light, visible light, or another wavelength value or range. Where the identification element  190  reflects light outside of the visible spectrum, it can be non-visible to a user. For example, the identification element  190  can include ultraviolet-reflective ink. As such, the identification element  190  can provide identification capabilities without being noticeable by a user. 
     In some embodiments, the detector  170  can directly detect an intrinsic characteristic of a band  110 . For example, various bands  110  can be of different materials, constructions, textures, and/or colors. The detector  170  can distinguish one or more characteristics of a given band  110  from those of another band  110 . The detector  170  can optically detect certain characteristics, such as color and reflectivity, of a band  110  and identify the band  110  based on whether it satisfies expected criteria relating to the detected characteristics. For example, the detector  170  can distinguish the color and reflectivity of a stainless steel band from the color and reflectivity of a brown leather band. Thereby, the watch body  100  can identify each of the bands  110  and perform corresponding actions. 
     In some embodiments, the detector  170  include a magnetic field sensor (e.g., compass, magnetometer, Hall Effect sensor, etc.) and the identification element  190  can include one or more magnets. For example, the detector  170  can detect the magnitude, orientation, or other characteristic of a magnetic field emitted by the identification element  190 . The detected characteristic can have a distinct signature that is unique to the identification element  190 . Thereby, the watch body  100  can identify the band  110  and perform corresponding actions. 
     By further example, where multiple magnets are included, the identification element  190  can include an arrangement of the magnets (e.g., different north-south orientations) that is distinct from the arrangement of another identification element  190  of a different band  110 . The magnets can be arranged across the lug  112 , such that insertion of the lug  112  into the channel  114  allows each of the magnets to pass across the detector  170 . Such action can automatically activate sensing by the detector  170 . The detector  170  can detect each of the magnets and determine an arrangement (e.g., north-south) thereof based on the magnetic fields of each magnet. The combined arrangement can have a distinct signature that is unique to the identification element  190 . Thereby, the watch body  100  can identify the band  110  and perform corresponding actions. 
     In some embodiments, the detector  170  of the watch can include or operate in concert with a compass of the watch. For example, the same compass that is operated to detect a magnetic field of the Earth can be operated to detect the identification element  190 . The presence of a magnetic field from the identification element  190  can be detected by the same compass that is then calibrated to detect the magnetic field of the Earth. Likewise, the removal and/or absence of the magnetic field from the identification element  190  can be detected by the same compass that is then calibrated to detect the magnetic field of the Earth 
     In some embodiments, the watch body  100  can detect an identification element  190  of a band  110  by using a detector that applies a communication protocol. Wireless or wired communication can be performed, at least in part, by a detector  170  that includes or operates in concert with a communication element (e.g., communication element  160 ) of the watch body  100 . Communication between the band  110  and the watch body  100  can employ a short-range communication method, such as near field communication (“NFC”), radio-frequency identification (“RFID”), Bluetooth, Wi-Fi, Wi-Fi Direct, short-range 802.11, and high frequency focused beams such as 60 GHz. Alternatively or additionally, communication between the band  110  and the watch body  100  can employ a high frequency communication method, such as WirelessHD, WiGig, and Wi-Fi IEEE 802.11ad. Alternatively or additionally, communication between the band  110  and the watch body  100  can be with ultra-wideband (“UWB”), using low energy levels for short-range, high-bandwidth communications over a large portion of the radio spectrum (e.g., &gt;500 MHz). 
     For example, the watch body  100  can be placed near the band  110 . The watch body  100  and the band  110  can include a wireless system that is configured to enable one-way or two-way communications. The one- or two-way communication may include an identification of the band  110  and the watch body  100  to initiate a data connection between the two devices. The user initiates a communication between the watch body  100  and the band  110  by placing the watch body  100  near the identification element  190  (e.g., a tag). In some embodiments, the watch body  100  is configured to automatically detect the presence of the identification element  190  and initiate an identification process or routine. The system may include a unique identifier or signature that may be used to authenticate the identity of the band  110 . 
     In some embodiments, the detector  170  include an antenna and the identification element  190  can include one or more features that reflect radiation. For example, the detector  170  can emit electromagnetic radiation (e.g., RF, WiFi, UWB, EHF, mmWave, etc.). The housing or other component of the watch body  100  can provide transmission of such radiation between the detector  170  and the identification element  190 . For example, the housing can provide a window that transmits radiation to and/or from the channel  114  and the lug  112 . The identification element  190  can include a surface, coating, or other feature that reflects the radiation. Such reflection can be passive or actively managed. The identification element  190  can be tuned to a resonant frequency, such that the reflection occurs at a particular frequency that is detectable by the detector  170 . The reflection of the radiation can be detected by the detector  170  and/or by another component capable of detecting such activity. The reflected radiation can be distinguished from the original emission and/or other sources of radiation to determine the presence or absence of the band  110 . The reflected radiation can have a distinct signature that is unique to the identification element  190 . Thereby, the watch body  100  can identify the band  110  and perform corresponding actions. 
     It will be understood that the antenna of the detector  170  can be an antenna that operates for other functions, such as communication with other external devices. It will be further understood that such communication can be performed while simultaneously detecting for any reflected radiation to determine the absence or presence of the band  110 . 
     In some embodiments, the detector  170  include a capacitive sensor and the identification element  190  can include one or more features that alter capacitance in a nearby region. The housing or other component of the watch body  100  can provide a surface or window for the sensor of the detector  170  to detect, by capacitive influence, the presence or absence of the identification element  190 . The identification element  190  can include a surface, coating, or other feature that, when brought into contact or proximity of the detector  170 , induces a change in the capacitance of the detector  170 . The change in the capacitance can be distinguished from other configurations of the detector  170  to determine the presence or absence of the band  110 . The change in the capacitance can have a distinct signature that is unique to the identification element  190 . Thereby, the watch body  100  can identify the band  110  and perform corresponding actions. 
     In some embodiments, the detector  170  include an induction coil and the identification element  190  can include one or more features that alter induction in a nearby region. The induction coil can be dedicated to detecting the identification element  190  or operable for other purposes, such as inductive changing of a power source of the watch body  100 . The identification element  190  can include a magnet or other feature that, when brought into proximity of the detector  170 , induces a current to flow through the detector  170 . The induced current can be distinguished from other configurations of the detector  170  to determine the presence or absence of the band  110 . The change in the detector  170  can have a distinct signature that is unique to the identification element  190 . Thereby, the watch body  100  can identify the band  110  and perform corresponding actions. 
     Referring now to  FIG.  6   , a method  200  can be performed by a watch body  100  to interact with a band  110 . In an operation  202 , the watch body  100  can initiate a scan for an identification element. The watch body  100  can be placed into a scanning mode based on manual and/or automated initiation. For example, the user can place the watch body  100  into a scanning mode by providing manual inputs to the watch body  100 . For at least a limited period of time thereafter, the watch body  100  can activate its components to scan for the identification element  190  of a band  110 . Alternatively or additionally, the watch body  100  can automatically activate its components after it senses the presence of an identification element  190 , for example as described above. Additionally or alternatively, the electronic device can initiate a scan for an identification element upon detection that the electronic device is worn by a user. For example, when the electronic device detects that it is being worn (e.g., based on proximity to a user as can be sensed by a sensor) after a period of not being worn, the electronic device can initiate a scan to detect the identification element of any band present. By further example, the electronic device can detect the presence of a band based on sensed changes, such as a change in impedance or inductance of a coil when the band is inserted into the electronic device, as discussed further herein. Such changes can be used to initiate a scan. Additionally or alternatively, the electronic device can initiate scans periodically or based on a predetermined schedule. 
     In an operation  204 , the watch body  100  can detect an identification element  190  of a band  110 . Examples of components and mechanisms for detecting the identification element  190  are described above. One of more of these components and/or mechanisms can be applied to effectively detect the identification element  190 . Once the identification element  190  has been detected, a record thereof can be stored within a memory  152  of the watch body  100 . The identification element  190  can be an indicator of a feature of the band  110 . For example, the identification element  190  can indicate a type, model, color, size, or other characteristic of the band  110 . Where the identification element  190  indicates one characteristic (e.g., model) of the band  110 , other characteristics (e.g., color, size) can be inferred. 
     The identification can serve as an input to determine an action to be performed by the watch body  100 . In an operation  206 , the watch body  100  can determine an action associated with the identification element  190 . Each of a variety of identification elements  190  corresponding to different bands  110  can be recorded in the memory  152  of the watch body  100 . Each of the recorded identification elements  190  can have associated therewith a corresponding action. The record of identification elements  190  and associated actions can be in the form of a table, array, or other data structure. When a given identification element  190  is detected, it can be compared with the recorded identification elements  190  to find a match and determine the corresponding action. While the foregoing discussion relates to referencing memory  152  onboard the watch body  100 , it will be recognized that the watch body  100  can reference another database apart from the watch body  100 . The association of identification elements  190  and corresponding actions can be preprogrammed, user-selected, or a result of machine-learning based on prior usage with one or more bands  110 . 
     In an operation  208 , the watch body  100  can perform the action that has been determined to be associated with the identification element  190 . For example, the recorded action corresponding to the detected identification element  190  can include instructions for execution by the processor  150  and/or other components of the watch body  100 . Alternatively or additionally, the action can include causing another device, apart from the watch body  100 , to execute instructions. The action can be performed automatically upon identification of a band  110 . Additionally or alternatively, the watch body  100  can provide a prompt requesting user confirmation of the action, and the action can be performed after user confirmation is received. Additionally or alternatively, a user can manually override or modify the action. 
     Various examples of actions are discussed below. Actions performed by the watch body  100  in response to detection of an identification element  190  include influencing regular operation of the watch body  100 . For example, the regular operation of the watch body  100  can be maintained with additional or altered features based on the selected band  110 . As such, the user&#39;s experience with the watch body  100  during its regular operation is enhanced. 
     In some embodiments, upon identifying a particular band  110 , the watch body  100  provides a feature of a visual user interface that corresponds to a characteristic of the band  110 . For example, the watch body  100  can display on the display  104  a feature that is substantially the same color as the band  110 . Alternatively or additionally, the feature can be a similar color, a matching color, or a complementary color. The feature can be any visible feature of the display  104 . Examples of features include watch hands, text, numbers, symbols, graphics, charts, markers, or any displayed item. One, some, or all of the features visible on the display  104  can be altered based on the color of the identified band  110 . By further example, the watch body  100  can display on the display  104  a feature that is associated with the band  110 , regardless of color selection. For example, displayed information, watch faces, menu items, and selectable icons can be selected based on the selection of band  110 . 
     In some embodiments, upon identifying a particular band  110 , other settings of the watch body  100  can be modified. A band  110  can be associated with an activity that is supported by the watch body  100 . For example, an exercise band can be worn when a user is exercising. Upon identification of the exercise band, actions conducive to an exercise session can be performed by the watch body  100 . For example, the watch body  100  can display particular information, track activity of the user, take a biometric reading, record a location of the user, launch an activity tracking app, and/or modify notifications settings (e.g., to be more prominent). By further example, a formal band can be worn in a more formal setting. Upon identification of the formal band, actions conducive to a formal setting can be performed by the watch body  100 . For example, the watch body  100  can display particular information, modify notifications settings (e.g., to be less prominent), provide reminders to the user, and/or record a location of the user. 
     Actions performed by the watch body  100  in response to detection of an identification element  190  include actions outside of the regular operation of the watch body  100 . For example, the watch body  100  can perform actions that are only available when a particular band  110  is detected. As such, the user&#39;s experience with the watch body  100  is expanded with the selection of bands  110 . 
     In some embodiments, a band  110  can include an identification element  190  that provides authorization for otherwise unavailable actions. For example, a band  110  can facilitate redemption of items of value. The band  110  can be used with the watch body  100  to redeem items of value, such as credit, gift cards, funds, cash, prizes, digital media, access to content (e.g., online content), goods, and/or services. The identification element  190  can provide information to the watch body  100  for authorizing redemption of an item of value. For example, the identification element  190  can include a code that is verifiable by an external device. As shown in  FIG.  7   , a system  300  can manage the redemption. The watch body  100  can identify a band  110  and communicate with an external device  310 . Information from the identification element  190  can be transmitted from the watch body  100  to the external device  310 . The external device  310  can verify the information and authorize redemption of an item of value. The external device  310  can further manage the redemption by executing a transfer to an account associated with the watch body  100 . Bands  110  that facilitate redemption of items of value can be provided by vendors, retailers, service providers, or entities that manage the redemption process. The bands  110  can be provided, exchanged, and transferred for sale or as gifts based on the value of the redeemable items. The bands  110  can be provided as promotional items in conjunction with an event. For example, bands  110  can be provided at a festival, convention, conference, concert, or reunion, to provide attendees possessing the bands  110  with access items of value that are associated with the event. Each attendee can access the items of value by using the bands  110  with their watch bodies  100 . 
     In some embodiments, a band  110  and a watch body  100  can interact and operate in a manner that is not necessarily perceivable by a user. For example, a watch body  100  can track usage of one or more bands  110 . The tracked usage information includes dates, times, durations, locations, activities, biometrics of the user, and/or environmental features in relation to periods before, during, and/or after usage of each band  110 . The tracked usage information can be collected during a background process of the watch body  100 . The tracked usage information can be output to a user or uploaded to an external device for analysis. The tracked usage information can be used for machine learning in relation to how each band  110  is used. 
     The watch body  100  can perform a variety of other actions upon identification of a band  110 . It will be recognized that the detection of an identification element  190  can be followed by any associated action that can be performed by the watch body  100 . For example, where the watch body  100  has the required capabilities, the watch body  100  launches an app, opens a website, starts a timer, displays a message, provides an alert, communicates with another device, and/or other functions. 
     Referring now to  FIGS.  8  and  9   , a watch can perform different actions when each of a variety of band combinations is detected. For example, multiple band portions can be provided across different sides of the watch body, and each band portion can be independently detected. 
     For example, as shown in  FIG.  8   , a first band portion  110 A and a second band portion  110 B can each be attached to a corresponding one of different (e.g., opposing) sides of the watch body  100  (e.g., at a given channel  114 ). The first band portion  110 A can have a characteristic that is the same as or different from a characteristic of the second band portion  110 B. Such characteristics can include a type, model, color, material, size, output, or other characteristic of the corresponding band portion. The characteristic can be detectable or undetectable to a user. 
     As shown in  FIG.  9   , a first detector  170 A on a first side of the watch body  100  can detect a first identification element  190 A of the first band portion  110 A, and a second detector  170 B on a second side of the watch body  100  can detect a second identification element  190 B of the second band portion  110 B. Based on and in response to these detections, the watch body can perform an action. An example of such an action includes providing an output  106  on the display  104  of the watch body  100 . The output  106  can optionally include a visual feature with a characteristic that corresponds to a characteristic of the first band portion  110 A and a characteristic that corresponds to a characteristic of the second band portion  110 B. Further examples include providing other outputs to a user, initiation a function, terminating a function, communicating with another device, and the like. 
     Referring now to  FIG.  10   , multiple detectors can operate in concert to detect identification elements of a band. The multiple detectors can cooperatively provide frequent detection of a band along with accurate and effective detection of the identity of the band. 
     For example, as shown in  FIG.  10   , a band  110  can include a first identification element  190 A and a second identification element  190 B. When the band  110  is attached to the watch body  100  (e.g., by inserting the lug  112  into the channel  114 ), the first identification element  190 A can be aligned with a first detector  170 A of the watch body  100 , and the second identification element  190 B can be aligned with a second detector  170 B of the watch body  100 . 
     It will be recognized that some detection mechanisms can consume more power or have other effects that would preferably be minimized. For example, the second detector  170 B can, when operated, consume more power than the first detector  170 A, when operated. In some embodiments, the first detector  170 A detects the band  110  (e.g., by the first identification element  190 A) in a manner that is different than a manner in which the second detector  170 B detects the second identification element  190 B to accommodate the differences in operation. For example, the first detector  170 A can detect the band  110  on a more frequent basis than the second detector  170 B detects the second identification element  190 B. For example, the first detector  170 A can be “always on” or otherwise be ready to detect the band  110  continuously or periodically. Upon detection of the band  110  by the first detector  170 A, the watch can determine that the band  110  is present and infer that the second identification element  190 B may also be present and available for detection. Based on the first detection, the second detector  170 B can be activated to detect the second identification element  190 B by any mechanisms described herein. By activating the second detector  170 B only after detecting the presence of the band  110  with the first detector  170 A, the operation of the second detector  170 B can be limited to when it is needed. Additionally or alternatively, the second detector  170 B can be deactivated upon detection that the band  110  is not present. Accordingly, power consumption by the second detector  170 B can be reduced without losing an ability to detect the band  110  when present. 
     Referring now to  FIGS.  11 - 13   , a detector can optically sense the identification element on a lug or another portion of a band. As discussed above, a light source can be provided to facilitate optical sensing by the detector. For example, the detector can include or be accompanied by a light source that illuminates the identification element, and the detector can optically detect the light reflected off of the identification element. 
     As shown in  FIG.  11   , a lug  112  or another portion of a band  110  can include an identification element  190  along a surface thereof. The identification element  190  can include at least one reference row and at least one code row providing patterns with feature that, when compared to the reference row, can indicate an identity or other characteristic of the band  110 . 
     A reference row can provide a basis for comparison with respect to other rows. A reference row  130  can be provided with a repeating pattern of a shape  132 . As used herein, a row providing a repeating pattern of a given shape is an arrangement of multiple instances of the given shape in a pattern, wherein the instances of the shape occur with at least one visible or otherwise detectable feature in common across the entire pattern. For example, the instances of the repeated shape can all have the same shape, size, dimensions, boundaries, color, periodicity, frequency, orientation, spacing, alignment, and the like. 
     A code row can provide a feature that, when compared to the reference row, can be used to identify the band. A code row  140  can be provided with a repeating pattern of a shape  142 . The shape  142  repeated along the pattern of the code row  140  can be distinct from the shape  132  that is repeated along the pattern of the reference row  130 . For example, a length of the shape  142  of the code row  140  can be different (e.g., shorter or longer) than a length of the shape  132  of the reference row  130 . The repeating pattern of the shape  142  of the code row  140  can optionally be a positive integer multiple (e.g., harmonic) of a frequency of the repeating pattern of the shape  132  of the reference row  130 . Accordingly, an integer number (e.g., 1, 2, 3, 4, etc.) of shapes  142  of the code row  140  can fit within a single length of the shape  132  of the reference row  130 . This allows a view  172  captured by the detector to detect and compare the integer number of shapes  142  to a single shape  132  of the reference row  130 . 
     It will be understood that any number of code rows can be provided. For example, an additional (e.g., second) code row  144  can be provided with a repeating pattern of a shape  146 . The shape  146  repeated along the pattern of the code row  144  can be distinct from the shape  132  of the reference row  130  and/or the shape  142  of the code row  140 . For example, a length of the shape  146  of the code row  144  can be different (e.g., shorter or longer) than a length of the shape  132  of the reference row  130  and/or the shape  142  of the code row  140 . The repeating pattern of the shape  146  of the code row  144  can optionally be a positive integer multiple (e.g., harmonic) of a frequency of the repeating pattern of the shape  132  of the reference row  130 . The positive integer multiple can be different than that of the shape  142  of the code row  140 . Accordingly, an integer number (e.g., 1, 2, 3, 4, etc.) of shapes  146  of the code row  144  can fit within a single length of the shape  132  of the reference row  130 . This allows a view  172  captured by the detector to detect and compare the integer number of shapes  142  to a single shape  132  of the code row  140 . 
     It will be understood that any number of reference rows can be provided. For example, an additional (e.g., second) reference row  134  can be provided with a repeating pattern of a shape  136 . The reference row  134  can be on an opposite side of the identification element  190  from the other (e.g., first) reference row  130 . The shape  136  repeated along the pattern of the reference row  134  can be the same as the shape  132  of the reference row  130 . For example, the shape  132  and the shape  136  can all have the same shape, size, dimensions, boundaries, color, periodicity, frequency, orientation, spacing, alignment, and the like. Accordingly, the code rows  140  and  144  can be compared to either one or both of the reference rows  130  and  134 . 
     A shown in  FIG.  12   , a detector (not shown) can capture a view  172  of at least a portion of the identification element  190 . Each of the shapes, or portions thereof, within the view  172  can be captured for analysis. For example, the shape(s) of the code row(s) can be compared to the shape(s) of the reference row(s). The shapes can have one or more features that are used as a basis for comparison. For example, such a feature can include a relative phase, amplitude, color, reflectivity, diffraction grating, and/or texture of the second repeating pattern with respect to the first repeating pattern. 
     The features of the shapes from rows captured in the view  172  can be compared to determine similarities and/or differences there between. In some embodiments, features to be compared can include a relative phase of at least two different repeating patterns. For example, the repeating patterns can have a detectable period. While the pattern can be different, a point within a given period (e.g., peak, trough, etc.) can be compared to a comparable point in a different pattern. For example, the phase of a pattern in a code row can be shifted (e.g., horizontally) relative to the phase of a reference row. The phase of each and/or a relative phase between pairs of patterns can be detected, quantified, and/or compared. The phases of both one or more code rows and/or one or more reference rows can be combined or otherwise analyzed, for example by summation. Further analysis can include, for example, discrete Fourier transform. The output can be used to determine an identify of the band among others and/or distinguish the band from other bands that have different identification elements (e.g., with different features). 
     It will be understood that a comparison of features can be based on any one or more of a variety of features. For example, such features across different patterns can include a relative phase, amplitude, color, reflectivity, diffraction grating and/or texture of the repeating patterns. Where different types of features are used, the features of the same type from different repeating patterns can be compared, and the different types of features can provide additional dimensions that can be used to distinguish the features of the rows. 
     The arrangement of the rows and the repeating patterns therein can facilitate the operation of the detector to capture and view with sufficient information to make an identification, even if less than an entirety of the identification element is captured within the view. For example, as shown in  FIG.  12   , a length L of the view  172  can extend to capture at least one shape  132  of the reference row  130 , a corresponding (e.g., integer) number of shapes  142  of a first code row  140 , and a corresponding (e.g., integer) number of shapes  146  of a second code row  144 , as well as any additional rows. 
     Because the shapes of each row repeats according to a pattern, the view  172  need not capture an entirety of any row. The length L can capture enough of one or more shapes to determine the characteristics of all of the shapes across an entire row. As such, the horizontal (e.g., along the length L) alignment of the view  172  (e.g., of the lug relative to the watch body or the identification relative to the detector) need not be limited to only one horizontal region of the identification element. This allows the detection to be made across a wide variety of horizontal alignment arrangements. 
     Because the shapes of each row repeats according to a pattern, the view  172  need not capture an entire portion of any one shape. For example, where a portion of one shape and a portion of its neighbor in the pattern are captured within the view  172 , the characteristics of either shape can be inferred by the combination of portions within the view  172 . 
     By further example, as shown in  FIG.  13   , a height H of the view  172  can extend to capture portions of multiple rows. The height H of the view  172  can extend across an entire height of all of the code rows. The height H of the view  172  can extend across an entire height of at least one of the reference rows or at least a portion of both reference rows. As shown in  FIG.  12   , the shapes of the different reference rows  130  and  134  can be the same, so that the view  172  need not capture an entire height of either one of the reference rows. For example, where a portion of a shape  132  from the first reference row  130  and a portion of a shape  136  from the second reference row  134  are captured within the view  172 , the characteristics of either shape can be inferred by the combination of portions within the view  172 . As such, the vertical (e.g., along the height H) alignment of the view  172  (e.g., of the lug relative to the watch body or the identification relative to the detector) need not be limited to only one vertical region of the identification element. This allows the detection to be made across a wide variety of vertical alignment arrangements. 
     Additionally or alternatively, the identification element  190  can include another symbol, such as a barcode, including a machine-readable representation of information in the form of one or more patterns. The symbol may be formed as patterns of dark (e.g., black) and light (e.g., white) bars, circles, dots or other shapes. Other patterns are contemplated, such as patterns of dots, concentric circles and the like. Other examples of barcodes include Universal Product Codes (UPCs), Code 39 barcodes, Code 128 barcodes, PDF417 barcodes, EZcode barcodes, DataMatrix barcodes, QR Codebarcodes, or barcodes that utilize any other type of barcode symbology. A 1D sensor or a 2D sensor can be used to capture images of adequate resolution (e.g., pixels) to detect the identification element  190  (e.g., barcode). The depth of focus of the sensor can be arranged so that the barcode is in focus when the band is swiped past the detector  170 . 
     Additionally or alternatively, the detector  170  can be configured to perform barcode scanning. In particular, the detector  170  can capture an image of the identification element  190  and use digital image processing techniques to decode the barcode. During a detection operation, the watch body  100  may prompt a user to line up the detector  170  with the identification element  190  in a particular manner, such as aligning the identification element  190  in the center of an image captured by the detector  170  and displayed on the display  104 . 
     Referring to  FIGS.  14  and  15   , a band can include an identification element that facilitates wireless communication from within an outer periphery of a lug of the band. The identification element can be housed within a portion of the lug that also helps secure the lug to the housing of the watch body. 
     As shown in  FIG.  14   , the lug  112  can include a locking element  116  within an opening of the body  210 . The locking element  116  may be positioned at any point along the body  210  and in any orientation. The locking mechanism can slideably move within the opening of the body  210  to engage a portion of the watch body. For example, when the lug  112  is received within the channel of the watch body, the locking element  116  can actuate and/or otherwise engage a portion of the watch body to secure the lug  112  within the channel. The locking element  116  can be released by a user to allow the lug  112  to be removed from the channel. The locking element  116  of the lug  112  can include one or more elements that can controllably protrude from the body  210  to engage the watch body. 
     As further shown in  FIG.  14   , the lug  112  can include one or more bumpers  118  that extend or protrude from a body  194  of the lug  112 . The bumpers  118  can be positioned at leading edges of the locking element  116  and distributed along the body  194 . The bumpers  118  can be positioned on one side or opposing sides of the body  194 . The bumpers  118  may include one or more alignment pads that act as a guide for the lug  112  when the lug  112  slides relative to a channel in the housing of the watch body. The bumpers  118  may have a rounded top surface that follows or substantially follows the contour of the body  194  while still protruding from the surface of the body  194 . The bumpers  118  may have a planar or substantially planar top surface. Although the bumpers  118  are shown in a rounded oblong or lozenge shape, the bumpers  118  may be curved, proud, flat, angled, have a raised edge and a flat interior or any combination thereof. 
     The bumpers  118  may be positioned on various parts of the body  194  of the lug  112 . For example, a top surface of the body  194  of the lug  112  may include one or more bumpers  118  and the bottom surface of the body  194  of the lug  112  may also include the same or additional bumpers  118 . The bumpers  118  may include a casing that is of rubber, plastic, nylon, or other such material. The material may be a material that acts to increase friction between the lug  112  and the channel of the housing of the watch body. The body  194  of the lug  112  may include one or more recesses in which the bumpers  118  may be placed. Additionally or alternatively, the bumpers  118  may be placed directly on top, bottom and/or side surfaces of the body  194  of the lug  112 . Further, the bumpers  118  may be disposed in one or more openings that extend entirely though an axis of the body  194  of the lug  112 . 
     The bumpers  118 , or at least a portion of each bumper  118 , extends or protrudes from one or more surfaces of the body  194  of the lug  112 . In such embodiments, the portion of the bumper  118  that extends beyond the surface of the body  194  of the lug  112  is used to: (1) increase friction between the lug  112  and the channel of the housing of the watch body into which the lug  112  is to be placed; and (2) maintain or substantially maintain spacing between one or more surfaces of the lug  112  and a surface of a channel of the housing of the watch body into which the lug  112  is to be placed. Accordingly, undesired movement, rattling and/or noise caused by any movement of the lug  112  may be reduced when the lug  112  is contained within the channel. 
     As shown in  FIG.  15   , a bumper  118  can contain an identification element  190  that facilitates wireless communication with a detector of a watch body. For example, an identification element  190  can include an antenna element  162  and an identification tag  166  (e.g., an NFC tag). The antenna element  162  can be a wound coil, an etched PCB, or another structure for receiving and/or emitting radiation. The identification tag  166  can be operably connected to the antenna element  162 . A magnetic (e.g., ferrite) core  164  can be provided (e.g., within the antenna element  162 ) to facilitate detection of the identification element  190  and/or enhance operation of the antenna element  162 . 
     The components of the identification element  190 , including the antenna element  162 , the magnetic (e.g., ferrite) core  164 , and/or the identification tag  166  can be housed within a casing  168  of the bumper  118 . For example, the casing  168  can be molded, potted, or otherwise formed about the other components of the bumper  118 . The casing  168  can seal the components of the identification element  190  from an external environment. Additionally, the casing  168  can define an outer periphery of the bumper  118 , including the portions thereof that extend beyond the body of the lug and engage the watch body. 
     While only one would coil is shown for the antenna element  162  in  FIG.  15   , it will be understood that a variety of coil arrangements can be provided. For example, the antenna element  162  may include two or more coils (e.g., a pair of coils) that are each wound around a respective core structure (e.g., a pair of corresponding core structures or support structures) that are mounted on, or formed as protrusions from, a surface. Optionally, a single wire can form all of the multiple (e.g., two) coils of the antenna element  162 . In one or more implementations, a multi-coil antenna module can communicate with a (e.g., mirrored) multi-coil antenna module in the watch housing to form one or more magnetic flux loops through the multi-coil antennas that can facilitate providing, exchanging, and/or receiving identification, power, and/or other communications between the processing circuitry of the wearable device and the band. 
     The watch body can be provided with low-power impedance detection circuitry to detect the presence of the identification element  190  near a detector (e.g., NFC radio). One or more additional detectors can be positioned at locations to be aligned with the identification element when the lug is within the channel of the watch body. Detection can be contactless (e.g., non-conductive) so that the components can be protected from Galvanic corrosion that may occur in a contact-based arrangement. The detection can also be autonomous, such that user intervention or explicit operations are not required. Additionally, the detection can be performed without requiring the band to provide its own power source. It will be recognized that a variety of other configurations are contemplated to provide wireless communication for detection of the identification element  190  of the band  110 . 
     Accordingly, watch bands described herein can facilitate a watch&#39;s ability to perform one or more operations based on the detected characteristic and configuration of the watch band. Characteristics of the watch band can change when placed in different configurations, and each of these characteristics can be correlated with each of the various configurations. The characteristics can be measured to detect in which of the various configurations the watch band is in. 
     Various examples of aspects of the disclosure are described below as clauses for convenience. These are provided as examples, and do not limit the subject technology.

     As described above, one aspect of the present technology may include the gathering and use of data available from various sources. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter ID&#39;s, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of advertisement delivery services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide mood-associated data for targeted content delivery services. In yet another example, users can select to limit the length of time mood-associated data is maintained or entirely prohibit the development of a baseline mood profile. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publicly available information. 
     To illustrate the interchangeability of hardware and software, items such as the various illustrative blocks, modules, components, methods, operations, instructions, and algorithms have been described generally in terms of their functionality. Whether such functionality is implemented as hardware, software or a combination of hardware and software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application. 
     A reference to an element in the singular is not intended to mean one and only one unless specifically so stated, but rather one or more. For example, “a” module may refer to one or more modules. An element proceeded by “a,” “an,” “the,” or “said” does not, without further constraints, preclude the existence of additional same elements. 
     Headings and subheadings, if any, are used for convenience only and do not limit the invention. The word exemplary is used to mean serving as an example or illustration. To the extent that the term include, have, or the like is used, such term is intended to be inclusive in a manner similar to the term comprise as comprise is interpreted when employed as a transitional word in a claim. Relational terms such as first and second and the like may be used to distinguish one entity or action from another without necessarily requiring or implying any actual such relationship or order between such entities or actions. 
     Phrases such as an aspect, the aspect, another aspect, some aspects, one or more aspects, an implementation, the implementation, another implementation, some implementations, one or more implementations, an embodiment, the embodiment, another embodiment, some embodiments, one or more embodiments, a configuration, the configuration, another configuration, some configurations, one or more configurations, the subject technology, the disclosure, the present disclosure, other variations thereof and alike are for convenience and do not imply that a disclosure relating to such phrase(s) is essential to the subject technology or that such disclosure applies to all configurations of the subject technology. A disclosure relating to such phrase(s) may apply to all configurations, or one or more configurations. A disclosure relating to such phrase(s) may provide one or more examples. A phrase such as an aspect or some aspects may refer to one or more aspects and vice versa, and this applies similarly to other foregoing phrases. 
     A phrase “at least one of” preceding a series of items, with the terms “and” or “or” to separate any of the items, modifies the list as a whole, rather than each member of the list. The phrase “at least one of” does not require selection of at least one item; rather, the phrase allows a meaning that includes at least one of any one of the items, and/or at least one of any combination of the items, and/or at least one of each of the items. By way of example, each of the phrases “at least one of A, B, and C” or “at least one of A, B, or C” refers to only A, only B, or only C; any combination of A, B, and C; and/or at least one of each of A, B, and C. 
     It is understood that the specific order or hierarchy of steps, operations, or processes disclosed is an illustration of exemplary approaches. Unless explicitly stated otherwise, it is understood that the specific order or hierarchy of steps, operations, or processes may be performed in different order. Some of the steps, operations, or processes may be performed simultaneously. The accompanying method claims, if any, present elements of the various steps, operations or processes in a sample order, and are not meant to be limited to the specific order or hierarchy presented. These may be performed in serial, linearly, in parallel or in different order. It should be understood that the described instructions, operations, and systems can generally be integrated together in a single software/hardware product or packaged into multiple software/hardware products. 
     In one aspect, a term coupled or the like may refer to being directly coupled. In another aspect, a term coupled or the like may refer to being indirectly coupled. 
     Terms such as top, bottom, front, rear, side, horizontal, vertical, and the like refer to an arbitrary frame of reference, rather than to the ordinary gravitational frame of reference. Thus, such a term may extend upwardly, downwardly, diagonally, or horizontally in a gravitational frame of reference. 
     The disclosure is provided to enable any person skilled in the art to practice the various aspects described herein. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. The disclosure provides various examples of the subject technology, and the subject technology is not limited to these examples. Various modifications to these aspects will be readily apparent to those skilled in the art, and the principles described herein may be applied to other aspects. 
     All structural and functional equivalents to the elements of the various aspects described throughout the disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. No claim element is to be construed under the provisions of 35 U.S.C. § 112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method claim, the element is recited using the phrase “step for”. 
     The title, background, brief description of the drawings, abstract, and drawings are hereby incorporated into the disclosure and are provided as illustrative examples of the disclosure, not as restrictive descriptions. It is submitted with the understanding that they will not be used to limit the scope or meaning of the claims. In addition, in the detailed description, it can be seen that the description provides illustrative examples and the various features are grouped together in various implementations for the purpose of streamlining the disclosure. The method of disclosure is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, as the claims reflect, inventive subject matter lies in less than all features of a single disclosed configuration or operation. The claims are hereby incorporated into the detailed description, with each claim standing on its own as a separately claimed subject matter. 
     The claims are not intended to be limited to the aspects described herein, but are to be accorded the full scope consistent with the language claims and to encompass all legal equivalents. Notwithstanding, none of the claims are intended to embrace subject matter that fails to satisfy the requirements of the applicable patent law, nor should they be interpreted in such a way.
