Title of Invention: DETERMINING PROXIMITY FOR DEVICES INTERACTING WITH MEDIA DEVICES Abstract: Embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and portable and wearable media devices. Media devices may include RF transceivers and proximity sensors for detecting a user, another wireless device, or both that are positioned in proximity of the media device and take one or more actions upon detecting proximity. Activity, content, data, playlist, media playback, command, control, data or file synchronization, and other functions may be handled by the media device subsequent to detecting proximity of another device and/or user in proximity of the media device. Moreover, those functions may be transferred back to the another device when the another device moves out of a proximity range of the media device. RF signatures, RF signal strength, RSSI, and proximity detection sensors may be used to detect proximity, location, and presence (e.g., of a user or other persons) relative to the media device.

FIELD Embodiments of the invention relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, wearable, hand held, and portable computing devices for facilitating communication of information. More specifically, disclosed are an ecosystem of wirelessly interconnected media devices that may detect proximity of other wireless devices and automatically establish a wireless communications link with those other wireless devices and use the link to handle content, media, information, command, control, and other functions. BACKGROUND Conventional wireless devices, such as smartphones, tablets, pads, cellphones, PDA, laptops, portable games, touch screen devices, and the like typically require software and user intervention (e.g., via a GUI or the like) to make the wireless device interoperable with other devices, such as other wireless devices and systems. Some wireless device may even require the user to go through the same steps/actions to get the wireless device to interact with another device, even thou the user has previously configured the devices to interact with each other. Ideally, a wireless device would sense its surrounding environment and the presence of other wireless devices and/or users, and based on content or programming, act to re-configure itself to serve a different role for a user until the circumstances change and the wireless device reverts back to its prior role or switches to yet another role. Moreover, the wireless device may be configured to take over (e.g., commandeers) one or more functions, tasks, etc. of another wireless device while the two wireless devices are within a predetermined proximity of one another. Additionally, it is desirable for some function of a wireless device to change in response to a location of another wireless device and/or a user relative to a position of the wireless device. Thus, what is needed are devices, methods, and software that allow a media device to sense its environment, determine proximity and/or location of other devices and/or users, and then take some action upon detecting proximity and/or location of other devices and/or users.

DETAILED DESCRIPTION Various embodiments or examples may be implemented in numerous ways, including as a system, a process, an apparatus, a user interface, or a series of program instructions on a non-transitory computer readable medium such as a computer readable storage medium or a computer network where the program instructions are sent over optical, electronic, or wireless communication links. In general, operations of disclosed processes may be performed in an arbitrary order, unless otherwise provided in the claims. A detailed description of one or more examples is provided below along with accompanying figures. The detailed description is provided in connection with such examples, but is not limited to any particular example. The scope is limited only by the claims and numerous alternatives, modifications, and equivalents are encompassed. Numerous specific details are set forth in the following description in order to provide a thorough understanding. These details are provided for the purpose of example and the described techniques may be practiced according to the claims without some or all of these specific details. For clarity, technical material that is known in the technical fields related to the examples has not been described in detail to avoid unnecessarily obscuring the description. FIG. 1 depicts a block diagram 190 of a media device 100 and wireless devices and users and/or persons positioned around the media device 100. As will be described in greater detail below, media device 100 may include a plurality of systems such as an audio/video system that includes one or more speakers 160 and one or more microphones 170, a radio frequency (RF) system including a plurality of RF transceivers configured for wireless communications using a plurality of different wireless communications protocols, and a proximity sensing system. A chassis 199 may include the various components of media device 100. Although only one media device 100 is depicted, there may be additional media devices as denoted by 121. In FIG. 1 media device 100 is configured to use one or more of its systems to detect proximity and/or location of other wireless devices such as smart phone 110 and tablet 120. Each wireless device may be connected with, held, or otherwise associated with a user such as user U1 for 110 and user U2 for 120. Some wireless user devices may not be associated with a user, such as laptop 130 for example. Media device 100 may also be configured to detect proximity and/or location of animate objects, such as people, denoted as person P1 and person P2. The arrangement and number of user devices, users, and persons depicted in FIG. 1 is for purposes of illustration only and the actual number and arraignment of user devices, users, persons, or other animate objects is not limited to that depicted in FIG. 1 and may differ from what is depicted in FIG. 1. The user devices, users, persons, or other animate objects depicted in FIG. 1 may be positioned at different distances from media device 100. Here, an arbitrary reference point 100r on the media device 100 is used to illustrate variations in approximate distance between one object and the media device 100, with: user device 110 at distance d1; user device 120 at distance d2; P1 at a distance d3; P2 at a distance d4; and user device 130 at a distance d5. Although not depicted, users U1 and U2 may also be positioned at an approximate distance from media device 100. At any given time some or all of the objects depicted in FIG. 1 may be positioned out of proximity of the media device 100 because their respective distance d is outside a proximity range of the media device 100 as denoted by a distance d0. For purposes of explanation, objects positioned approximately at or beyond d0 are outside of proximity detection range of media device 100. For example, person P2 and user device 130 are positioned beyond d0 as denoted by distances d4 and d5 respectively. Here d0 may represent a maximum proximity detection range for one or more systems of media device 100, such as a proximity sensing system. However, other systems of media device 100 may be configured to detect proximity of objects (e.g., user devices) beyond the distance d0, such as the aforementioned RF system. The proximity and RF systems will be described in greater detail below. Media device 100 may be configured via hardware, software, or both to take some action in response to detecting proximity of other wireless devices, such as the user devices (110, 120), and/or proximity of objects such as (U1, U2, P1, P2). Here, media device 100, using its RF system, detects a wireless signature (e.g., a RF signature) of user devices 110 and 120. A RF signal strength of radio transmissions from the wireless systems of user devices 110 and 120 may be detected by the RF system of media device 100 and processed to determine proximity and/or location of one or more wireless devices, such as the user devices 110 and 120. After detecting one or more wireless devices, the media device 100 may establish a wireless communications link with one or more of those wireless devices. In FIG. 1, after detecting proximity, the RF system of media device 100 may analyze the RF signature of each wireless device to determine the wireless communications protocol(s) used by that device and determine if one of its RF transceivers is protocol compatible with the protocol(s) of each wireless device. If there is compatibility, then the RF system activates the appropriate RF transceiver and establishes a wireless communications link with the wireless device. For example, in FIG. 1, user device 120 may be wirelessly communicating using a wireless network protocol (e.g., IEEE 802.11a/b/g/n (WiFi)) and user device 110 may be wirelessly communicating using Bluetooth protocol (BT). A WiFi communications link 128 may be established by media device 100 with user device 120 and a BT communications link 126 may be established by media device 100 with user device 110. Temporally, the detecting of any of proximity, analyzing RF signal strength, RF signature need not occur at the same time and may be spread out over time for the one or more wireless devices that are encountered by media device 100. After establishing the wireless communications link, media device 100 may take one or more actions. For example, after establishing link 128 with user device 120, media device 100 may take an action a2 including but not limited to: accessing data from user device, transferring data to/from user device, taking total or partial control of user device, issue commands to user device, receive commands from user device, relinquish control to user device, download data from user device, access content on user device, service content on user device, access a playlist on user device, playback content from user device, cause an application to be downloaded/installed on user device, just to name a few. Similarly, after establishing link 126 with user device 110, media device 100 may take an action a1. Action a1 may be those described above for action a2. FIG. 2 illustrates an exemplary computer system 200 suitable for use in the system 190 depicted in FIG. 1. In some examples, computer system 200 may be used to implement computer programs, applications, configurations, methods, processes, or other software to perform the above-described techniques. Computer system 200 includes a bus 202 or other communication mechanism for communicating information, which interconnects subsystems and devices, such as one or more processors 204, system memory 206 (e.g., RAM, SRAM, DRAM, Flash), storage device 208 (e.g., Flash, ROM), disk drive 210 (e.g., magnetic, optical, solid state), communication interface 212 (e.g., modem, Ethernet, WiFi), display 214 (e.g., CRT, LCD, touch screen), input device 216 (e.g., keyboard, stylus), and cursor control 218 (e.g., mouse, trackball, stylus). Some of the elements depicted in computer system 200 may be optional, such as elements 214-218, for example and computer system 200 need not include all of the elements depicted. According to some examples, computer system 200 performs specific operations by processor 204 executing one or more sequences of one or more instructions stored in system memory 206. Such instructions may be read into system memory 206 from another non-transitory computer readable medium, such as storage device 208 or disk drive 210 (e.g., a HD or SSD). In some examples, circuitry may be used in place of or in combination with software instructions for implementation. The term “non-transitory computer readable medium” refers to any tangible medium that participates in providing instructions to processor 204 for execution. Such a medium may take many forms, including but not limited to, non-volatile media and volatile media. Non-volatile media includes, for example, optical, magnetic, or solid state disks, such as disk drive 210. Volatile media includes dynamic memory, such as system memory 206. Common forms of non-transitory computer readable media includes, for example, floppy disk, flexible disk, hard disk, SSD, magnetic tape, any other magnetic medium, CD-ROM, DVD-ROM, Blu-Ray ROM, USB thumb drive, SD Card, any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, RAM, PROM, EPROM, FLASH-EPROM, any other memory chip or cartridge, or any other medium from which a computer may read. Instructions may further be transmitted or received using a transmission medium. The term “transmission medium” may include any tangible or intangible medium that is capable of storing, encoding or carrying instructions for execution by the machine, and includes digital or analog communications signals or other intangible medium to facilitate communication of such instructions. Transmission media includes coaxial cables, copper wire, and fiber optics, including wires that comprise bus 202 for transmitting a computer data signal. In some examples, execution of the sequences of instructions may be performed by a single computer system 200. According to some examples, two or more computer systems 200 coupled by communication link 220 (e.g., LAN, Ethernet, PSTN, or wireless network) may perform the sequence of instructions in coordination with one another. Computer system 200 may transmit and receive messages, data, and instructions, including programs, (i.e., application code), through communication link 220 and communication interface 212. Received program code may be executed by processor 204 as it is received, and/or stored in disk drive 210, or other non-volatile storage for later execution. Computer system 200 may optionally include a wireless transceiver 213 in communication with the communication interface 212 and coupled 215 with an antenna 217 for receiving and generating RF signals 221, such as from a WiFi network, BT radio, or other wireless network and/or wireless devices, for example. Examples of wireless devices include but are not limited to those depicted in FIG. 1 such as media device 100 and user devices 110 and 120. FIG. 3 depicts an example 300 of a media device detecting proximity of wireless user device, wirelessly linking with the user device, and optionally taking an action using the wireless link. In FIG. 3, a user U3 may be carrying a wireless device, such as a data capable strap band, wristband, wristwatch, or wireless activity monitoring and reporting device, for example, denoted for purposes of further explanation as wireless device 301. In the example, wireless device 301 is depicted as being worn about a wrist 304 of user U3, but wireless device 301 may be worn, attached, or otherwise connected with some other part of the body, clothing, apparel, headwear, footwear, etc. of user U3 and is not limited to the configuration depicted in FIG. 3. The wireless device 301 is depicted in enlarged detail as denoted by dashed arrow 302 to aid in explaining the present application. User U3 moves 305 into proximity detection range of media device 100 such that at a distance d6 a RF signature of a wireless transmission 311 from wireless device 301 is detected by the RF system of media device 100. Here, antenna 324 is coupled with the RF system and optionally may be de-tunable 329 as will be described below. At least at the distance d6, a RF signal strength of the wireless transmissions 311 from wireless device 301 is sufficient (e.g., is of adequate signal strength) for the RF system to detect and analyze the RF signature of 311. The RF system analyzes (e.g., using hardware, software, an algorithm, a processor, controller, DSP, etc.) the signature of 311 and determines whether or not the RF signature conforms to a wireless protocol that is compatible with one or more of its plurality of RF transceivers. For purposes of explanation, it is assumed that the RF signature of transmission 311 is compatible with a wireless protocol of one of the RF systems transceivers. Media device 100 establishes a wireless communications link 313 with wireless device 301. Upon establishing the wireless communications link 313, the media device 100 may take some action a3. If action a3 is taken, then action a3 may be application and/or wireless user device specific. For example, action a3 may comprise maintaining the wireless communications link 313 for future wireless communication exchanges between media device 100 and wireless device 301. As another example, the establishing the wireless communications link 313 may comprise a BT radio link between media device 100 and wireless device 301, and the action a3 may comprise switching from BT radio to WiFi radio for wireless communication exchanges between media device 100 and wireless device 301, such that media device 100 and wireless device 301 communicate using their respective WiFi transceivers. WiFi communications may include the media device 100 and the wireless device 301 communicating with each other via a wireless network (e.g., wireless network 370) using a WiFi router or the like. The following example is just one scenario of the type of action or actions that may be taken by the media device 100. For purposes of this example, wireless device 301 comprises a wearable device such as wireless activity monitoring and reporting device. While being worn by user U3, wireless device 301 has collected data (e.g., from one or more sensors carried by 301) and stored the data as denoted by 303. Data 303 may include biometric data gathered from sensing various systems or portions of user U3's body, the data 303 may have been entered by the user U3 using an application (e.g., an App) running on a smartphone, tablet, pad, computer, or the like, and data 303 may include information on calorie intake, calories burned (e.g., through activity), periods of rest, periods of sleep, body temperature, ambient temperature, motion data from exercise, running, walking, bicycling, swimming, etc. The data 303 may be quite extensive and the foregoing are non-limiting examples. Data 303 may include user defined information such as an alarm to wake the user U3 up at a preset time or within a preset range of times. The actual triggering of the alarm may comprise using some portion of the data 303 to determine how well rested the user U3 is and then using that portion of data 303 to wake up user U3 earlier or later, depending on how well user U3 slept. The alarm may be for any definable period such as time of day, day or days of the week, etc. The alarm may be configured to cause the wireless device 301 to give a notification to user U3 to that announces the triggering of the alarm event. For example, while worn on the wrist of user U3, the wireless device 301 may be configured to vibrate to notify user U3 that the alarm has triggered and it is time to wake up. Alternatively, the wireless device 301 may emit sound or light to notify user U3. Here, after the wireless communications link 313 is established between media device 100 and wireless device 301, the action a3 taken by media device 100 may include transferring some or all of the data 303 stored in wireless device 301 (e.g., in a non-volatile memory such as Flash). On the other hand, the action a3 taken by media device 100 may include transmitting the data associated with the alarm from the wireless device 301 to the media device 100. Furthermore, after the data for the alarm is transmitted to the media device 100, the media device 100 may take over the processing (e.g., using its controller) and handling of the alarm. Media device 100 may use one of its systems (e.g., its A/V system) to notify user U3 that the alarm has triggered. For example, speaker 160 may be used to audibly notify user U3 that the alarm has triggered. Media device 100 may commandeer functions, data, actions, activities, communications, etc. that would otherwise be handled by wireless device 301. As another example, absent the wireless link 313 between wireless device 301 and media device 100, the wireless device 301 may be configured to connect with a communications network using a wired connection (e.g., a USB port), a wireless connection (e.g., Bluetooth or WiFi), or both. Further, the wireless device 301 may use the wired/wireless connection to export at least a portion of the data 303. The data 303 may be uploaded to a web page, a web site, a social media site, etc. to be processed or viewed by the user U3 or other interested parties, such as friends in a social, a professional network, or a group of like-minded individuals (e.g., interested in health and exercise). However, while the wireless link 313 is active, the media device 100 may capture the data 303 or some portion of the data 303 and take some action a3 with regard to the data 303. As one example, media device 100 may be in wireless communication 371 with a wireless network 370 (e.g., WiFi, WiMAX, Cellular) and may harvest whatever data 303 is appropriate, and transmit 373 via the wireless network 370, that data 303a to the Internet, Cloud, NAS, Web page, web site, etc. generally denoted as resource 350. For example, data 303a may be transmitted to a web page of user U3 for display, analysis, processing, reporting progress against set goals, etc. In FIG. 3, the wireless device 301 may move out of proximity of the media device 100 as denoted by arrow 309 and distance d8. After moving out of proximity, the wireless device 301 may regain control over whatever functions, processes, data, etc. that were commandeered by the media device 100 and/or the media device 100 may relinquish control of the commandeered function(s) back to the wireless device 301. Furthermore, after moving 309 out of range the wireless device 301 may use its native RF system to wirelessly communicate with another wireless resource, such as WiFi network 370, for example. For example, data 303 or a portion thereof may be transmitted to resource 350 using a wireless link 377 where it is stored as data 303a. The above description using the wireless device 301 as an example may be applied to other wireless user devices, such as smartphones, tablets, pads, laptop computers, cell phones, and the like, and is not limited to the wireless device 301 depicted in FIG. 3. Other systems in media device 100 may detect proximity of user U3, such as proximity sensing system that uses one or more of acoustic, optical, vibration, or temperature sensors (e.g., a non-contact temperature sensor) to detect the presence of a user or other persons or objects within proximity of the media device 100. In FIG. 3, the proximity sensing system may be used to detect the presence of user U3 in isolation or in combination with the RF system detecting 311 the RF signature of the wireless device 301. For example, as the user U3 moves 305 into proximity of the media device 100, the proximity sensing system may detect presence of user U3 at a distance d7. Here, if the wireless device 301 is being worn by user U3, then d6 and d7 may be approximately equal. On the other hand, d6 and d7 may not be approximately equal to each other, if for example, user U3 has removed the wireless device 301 from his/her body (e.g., taken 301 off the wrist). At distance d7, the detection of user U3 by the proximity sensing system may activate one or more functions in media device 100 including but not limited to waking the media device 100 up from a standby state, causing the RF system to begin listening for RF signatures (e.g., 311), cause the A/V system to indicate a presence has been detected using any of sound, light, and vibration, just to name a few. FIG. 4 depicts another example 400 of a media device detecting proximity of wireless user device, wirelessly linking with the user device, and optionally taking an action using the wireless link. Here, wireless user device 420 comprises a tablet or pad (e.g., an iPad or Galaxy Note) and the wireless user device 420, a user U4 or both, move 405 into proximity range (e.g., distance d6 and/or d7) of media device 100 and are detected by the proximity system, the RF system, or both as described above. RF signature 411 of wireless user device 420 is detected by the RF system and is found to be protocol compatible with one or more of its RF transceivers and a wireless communications link 413 is established between media device 100 and wireless user device 420. Action(s) a4 taken by media device 100 after establishing the wireless communications link 413 may be application and/or wireless user device specific. As one example, prior to moving 405 into proximity of media device 100, the wireless user device 420 may be playing back content (e.g., music, video, images, etc.) and user U4 may be using a GUI on a display 421 to control the playback of the content. The content being played back may comprise data 403 that is resident (e.g., in its data storage system) on the wireless user device 420 and/or data 403 may comprise a playlist or gallery and the content may reside external to the wireless user device 420 such as in resource 450 (e.g., Cloud, Web page, NAS, or Internet) where the content 403c may comprise one or more files such as MP3, JPEG, MPEG4, FLAC, AIFF, WAV, etc., for example. Action a4 may comprise wirelessly transmitting a copy of the playlist in data 403 to the media device 100 and the media device 100 may commandeer the playback function and take over playback of the content using the systems of the media device 100, such as its A/V system. If the content resides on the wireless user device 420, action a4 may also comprise wirelessly transmitting a copy of some or all of the content to the media device 100 (e.g., to a data storage system of media device 100). Media device 100 may not have data storage capacity sufficient to store all of the content and may buffer the content in manageable portions. Alternatively, if the content resides in resource 450 (e.g., content 403c), then the data 403 may include a URL or some other form of address information that media device 100 may use to wirelessly access (471, 473) the content 403c from resource 450 (e.g., using wireless network 470). Resource 450 is just one example of an external location for content and the present application is not limited to the example depicted in FIG. 4. Prior to moving 405 into proximity of media device 100, the wireless user device 420 may have accessed content 403c using another wireless network, such as cellular network 450 or the like, and wireless communications links (481, 483) were used to access the content 403c. Action a4 may comprise media device 100 commandeering the handling of content 403c by using its own wireless resources such as its RF system and wireless network 470 to wirelessly access (471, 473) the content 403c from resource 450. User U4 may have been using an A/V system of the wireless user device 420 to experience the content 403c (e.g., using headphones, earphones) and action a4 may comprise commandeering the A/V function and causing playback to occur over speaker 160 or other components of the NV system of media device 100. As another example, if prior to moving 405 into proximity of the media device 100, user U4 was having a VoIP conversation (e.g., Skype™) on wireless user device 420, action a4 may comprise commandeering the a VoIP conversation and using it's A/V system (e.g., MIC 170 and SPK 160) to handle the conversation. Media device 100 may include a display (e.g., a touch screen, LCD, OLED etc.) and any video portions of the VoIP conversation may be commandeered and presented on that display. In some examples, the media device 100, the wireless user device 420, or both may include software and/or data fixed in a non-transitory computer readable medium an configured to allow the media device 100 and wireless user device 420 to communicate with each other, arbitrate access, command, and control between each other, and determine which wireless communication protocols to use. For purposes of explanation, the aforementioned software and/or data may comprise a configuration CFG 425 for media device 100 and an application APP 404 for wireless user device 420. Action a4 may comprise media device 100 acting to download APP 404 on wireless user device 420 after the wireless communications link 413 is established. Resource 450 may include a location where a file or the like for APP 404 is stored and media device 100 may access the file and use its wireless resources (e.g., 413, 471, 473) to obtain and install the APP 404 on wireless user device 420. In subsequent encounters between the wireless user device 420 and media device 100 (e.g., when they are in proximity of each other) the APP 404 need not be reinstalled and may serve to allow both devices to interact with each other. Furthermore, in subsequent encounters between the wireless user device 420 and media device 100 (e.g., when they are in proximity of each other) the APP 404 may have been updated or otherwise revised and action a4 may comprise installing an updated version of APP 404 on the wireless user device 420. Attention is now directed to FIG. 5 where a profile view depicts one example 500 of media device 100 that may include on a surface 199s (e.g., a top surface) of chassis 199, a plurality of optional control elements 503-512, and one or more proximity detection islands (four are depicted) denoted as 520. Some of the elements depicted in FIG. 5 are described in reference to FIG. 8 below. Media device 100 may include one or more speakers 160, one or more microphones 170, a display 580, a section 550 for other functions such as SEN 895, VID 890, or other, and antenna 324 which may be tunable 329. Each proximity detection island 520 may be configured to detect 597 proximity of one or more persons, such as user U5 as will be described in greater detail below. The layout and position of the elements on chassis 199 of media device 100 are examples only and actual layout and position of any elements will be application specific and/or a matter of design choice, including ergonomic and esthetic considerations. As will be described in greater detail below, detection of presence of user U5 may occur with or without the presence of one or more user devices 202, such as user devices 210 and 220 depicted in FIG. 5. Circuitry and/or software associated with operation of proximity detection islands 520 may work in conjunction with other systems in media device 100 to detect presence of one or more user devices 202, such as RF system 807 detecting RF signals 563 and/or 565 (e.g., via antenna 324) from user devices 555 and 557 or MIC's 170 detecting sound, for example. Detection of presence may be signaled by media device 100 in a variety of ways including but not limited to light (e.g., from 520 and/or 503-512), sound (e.g., from SPK 160), vibration (e.g., from SPK 160 or other), haptic feedback, tactile feedback, display of information (e.g., DISP 580), RF transmission (e.g., 126), just to name a few. SPK 160 and DISP 580 may be positioned on a front surface 199f of chassis 199. A bottom surface 199b of chassis 199 may be configured to rest on a surface such as a table, desk, cabinet, or the like. Other elements of media device 100 may be positioned on a rear surface 199r of chassis 199, such as another MIC 170. Non-limiting examples of optional control elements 503-512 include a plurality of controls 512 (e.g., buttons, switches and/or touch surfaces) that may have functions that are fixed or change based on different scenarios as will be described below, controls 503 and 507 for volume up and volume down, control 509 for muting volume or BT paring, control 506 for initiating or pausing playback of content, control 504 for fast reversing playback or skipping backward one track, and control 508 for fast forwarding playback or skipping forward one track. Some are all of the control elements 504-512 may serve multiple rolls based on changing scenarios. For example, for playback of video content or for information displayed on display 580 (e.g., a touch screen), controls 503 and 507 may be used to increase “+” and decrease “−” brightness of display 580. Control 509 may be used to transfer or pick up a phone call or other content on a user device 555 and/or 557, for example. Proximity detection islands 520 and/or control elements 503-512 may be backlit (e.g., using LED's or the like) for night or low-light visibility. Moving on to FIG. 6, a block diagram 600 depicts one example of a proximity detection island 520. Proximity detection island 520 may be implemented using a variety of technologies and circuit topologies and the example depicted in FIG. 6 is just one such non-limiting example and the present application is not limited to the arrangement of elements depicted in FIG. 6. Some of the elements depicted in FIG. 5 are described in reference to FIG. 8 below. One or more proximity detection islands 520 may be positioned on, connected with, carried by or otherwise mounted on media device 100. For example, proximity detection island 520 may be mounted on a top surface 199t of chassis 199. A structure 650 made from an optically transmissive material such as glass, plastic, a film, an optically transparent or translucent material, or the like. Structure 650 may be made from a material that allows light 603, 607, 617, and 630 to pass through it in both directions, that is, bi-directionally. Structure 650 may include apertures 652 defined by regions 651 (e.g., an opaque or optically reflective/absorptive material) used for providing optical access (e.g., via apertures 652) to an environment ENV 898 external to the media device 100 for components of the proximity detection island 520. Structure 650 may be configured to mount flush with top surface 199t, for example. In some examples, structure 650 may not include regions 651. Proximity detection island 520 may include at least one LED 601 (e.g., an infrared LED-IR LED) electrically coupled with driver circuitry 610 and configured to emit IR radiation 603, at least one IR optical detector 605 (e.g., a PIN diode) electrically coupled with an analog-to-digital converter ADC 612 and configured to generate a signal in response to IR radiation 607 incident on detector 605, and at least one indicator light 616 electrically coupled with driver circuitry 614 and configured to generate colored light 617. As depicted, indicator light 616 comprises a RGB LED configured to emit light 617 in a gambit of colors indicative of status as will be described below. Here, RGB LED 616 may include four terminals, one of which coupled with circuit ground, a red “R” terminal, a green “G” terminal, and a blue “B” terminal, all of which are electrically connected with appropriate circuitry in driver 614 and with die within RGB LED 616 to effectuate generation of various colors of light in response to signals from driver 614. For example, RGB LED 616 may include semiconductor die for LED's that generate red, green, and blue light that are electrically coupled with ground and the R, G, and B terminals, respectively. One skilled in the art will appreciate that element 616 may be replaced by discrete LED's (e.g., separate red, green, white, and blue LED's) or a single non-RGB LED or other light emitting device may be used for 616. The various colors may be associated with different users who approach and are detected in proximity of the media device and/or different user devices that are detected by the media device. Therefore, if there are four users/and our user devices detected, then: the color blue may be associated with user #1; yellow with user #2; green with user #3; and red with user #4. Some users and or user devices may be indicated using alternating colors of light such as switching/flashing between red and green, blue and yellow, blue and green, etc. In other examples other types of LED's may be combined with RGB LED 616, such as a white LED, for example, to increase the number of color combinations possible. Optionally, proximity detection island 520 may include at least one light sensor for sensing ambient light conditions in the ENV 898, such as ambient light sensor ALS 618. ALS 618 may be electrically coupled with circuitry CKT 620 configured to process signals from ALS 618, such as optical sensor 609 (e.g., a PIN diode) in response to ambient light 630 incident on optical sensor 609. Signals from CKT 620 may be further processed by ADC 622. The various drivers, circuitry, and ADC's of proximity detection island 520 may be electrically coupled with a controller (e.g., a pC, a pP, an ASIC, or controller 801 of FIG. 8) that is electrically coupled with a bus 645 (e.g., bus 810 of FIG. 8) that communicates signals between proximity detection island 520 and other systems of media device 100. Proximity detection island 520 may include auditory system AUD 624 configured to generate sound or produce vibrations in response to presence detection or other signals. AUD 624 may be mechanically coupled 641 with chassis 199 to cause chassis 199 to vibrate or make sound in response to presence detection or other signals. In some examples AUD 624 may use SPK 160 to generate sound or vibration. In other examples AUD 624 may use a vibration motor, such as the type used in smartphones to cause vibration when a phone call or notification is received. In yet another example, AUD 624 may use a piezoelectric film that deforms in response to an AC or DC signal applied to the film, the deformation generating sound and/or vibration. In yet other examples, AUD 624 may be connected with or mechanically coupled with one or more of the control elements and/or one or more of the proximity detection islands 520 depicted in FIG. 5 to provide haptic and/or tactile feedback. Upon detecting and acknowledging an approach by a user and/or user device, media may generate sound (e.g., from SPK 160) in a rich variety of tones and volume levels to convey information and/or media device status to the user. For example, a tone and volume level may be used to indicate the power status of the media device 100, such as available charge in BAT 835 of power system 811. The volume of the tone may be louder when BAT 835 is fully charged and lower for reduced levels of charge in BAT 835. Other tones and volume levels may be used to indicate the media device 100 is ready to receive input from the user or user device, the media device 100 is in wireless communications with a WiFi router or network, cellular service, broadband service, ad hoc WiFi network, other BT enabled devices, for example. Proximity detection island 520 may be configured to detect presence of a user U6 (or other person) that enters 671 an environment 898 the media device 100 is positioned in. Here, entry 671 by user U6 may include a hand 601h or other portion of the user U6 body passing within optical detection range of proximity detection island 520, such as hand 601h passing over 672 the proximity detection island 520, for example. IR radiation 603 from IRLED 603 exiting through portal 652 reflects off hand 601h and the reflected IR radiation 607 enters portal 652 and is incident on IR detector 605 causing a signal to be generated by ADC 612, the signal being indicative of presence being detected. RGB LED 616 may be used to generate one or more colors of light that indicate to user U6 that the user's presence has been detected and the media device is ready to take some action based on that detection. The action taken will be application specific and may depend on actions the user U6 programmed into CFG 825 using APP 425, for example. The action taken and/or the colors emitted by RGB LED 616 may depend on the presence and/or detection of a user device 557 in conjunction with or instead of detection of presence of user U6 (e.g., RF 565 from device 557 by RF 807). As described above, proximity detection island 520 may optionally include ambient light sensor ALS 618 configured to detect ambient light 630 present in ENV 898 such as a variety of ambient light sources including but not limited to natural light sources such as sunny ambient 631, partially cloudy ambient 633, inclement weather ambient 634, cloudy ambient 635, and night ambient 636, and artificial light ambient 632 (e.g., electronic light sources). ALS 618 may work in conjunction with IRLED 610 and/or IR detector 605 to compensate for or reduce errors in presence detection that are impacted by ambient light 630, such as IR background noise caused by IR radiation from 632 or 631, for example. IR background noise may reduce a signal-to-noise ratio of IR detector 605 and cause false presence detection signals to be generated by ADC 612. ALS 618 may be used to detect low ambient light 630 condition such as moonlight from 636 or a darkened room (e.g., light 632 is off), and generate a signal consistent with the low ambient light 630 condition that is used to control operation of proximity detection island 520 and/or other systems in media device 100. As one example, if user approaches 671 proximity detection island 520 in low light or no light conditions as signaled by ALS 618, RGB LED 616 may emit light 617 at a reduced intensity to prevent the user U6 from being startled or blinded by the light 617. Further, under low light or no light conditions AUD 624 may be reduced in volume or vibration magnitude or may be muted. Additionally, audible notifications (e.g., speech or music from SPK 160) from media device 100 may be reduced in volume or muted under low light or no light conditions (see FIG. 9). Structure 650 may be electrically coupled 681 with capacitive touch circuitry 680 such that structure 650 is operative as a capacitive touch switch that generates a signal when a user (e.g., hand 601h) touches a portion of structure 650. Capacitive touch circuitry 680 may communicate 682 a signal to other systems in media device 100 (e.g., I/O 105) that process the signal to determine that the structure 650 has been touched and initiate an action based on the signal. A user's touch of structure 650 may trigger driver 614 to activate RGB LED 616 to emit light 617 to acknowledge the touch has been received and processed by media device 100. Reference is now made to FIG. 7, where top plan views of different examples of proximity detection island 520 configurations are depicted. Although the various example configurations and shapes are depicted as positioned on top surface 199t of chassis 199, the present application is not so limited and proximity detection islands 520 may be positioned on other surfaces/portions of media device 100 and may have shapes different than that depicted. Furthermore, media device 100 may include more or fewer proximity detection islands 520 than depicted in FIG. 7 and the proximity detection islands 520 need not be symmetrically positioned relative to one another. Actual shapes of the proximity detection islands 520 may be application specific and may be based on esthetic considerations. Configuration 702 depicts five rectangular shaped proximity detection islands 520 positioned on top surface 199t with four positioned proximate to four corners of the top surface 199t and one proximately centered on top surface 199t. Configuration 704 depicts three circle shaped proximity detection islands 520 proximately positioned at the left, right, and center of top surface 199t. Configuration 706 depicts four hexagon shaped proximity detection islands 520 proximately positioned at the left, right, and two at the center of top surface 199t. Finally, configuration 708 depicts two triangle shaped proximity detection islands 520 proximately positioned at the left, right of top surface 199t. In some examples there may be a single proximity detection island 520. Proximity detection islands 520 may be configured to operate independently of one another, or in cooperation with one another. Other elements such as one or more of MIC 170 may be included on surface 199t and positioned in various configurations. One or more of MIC 170 may be used in conjunction with one or more of the Proximity detection islands 520 to detect presence and/or proximity of users, for example. Each MIC 170 may include a directional pattern configured to allow the MIC 170 to detect sound from a particular direction or vector. For example, each MIC 170 may have a polar pattern suitable for the intended application including but not limited to omni-directional, directional, bi-directional, uni-directional, bi-polar, uni-polar, any variety of cardioid pattern, and shotgun, and those polar patterns may be the same or may differ among the MIC's 170. The MIC's 170 need not be positioned on a top surface of chassis 199 and other portions of chassis 199 such as the front, back, sides, etc. may have one or more of the MIC's 170 positioned on them. The polar patterns of one or more of the MIC's 170 may overlap one another. A signal from each MIC 170 may be combined and/or processed (e.g., with a DSP and/or algorithms) with signals from other MIC's 170 to detect presence, location, proximity, motion, direction of motion of an object, etc. Additionally, signals from one or more of the MIC's 170 may be combined with signals from one or more of the proximity detection islands 520 and/or RF system 807 and its de-tunable antenna (824, 829) to detect presence, location,
