     DETAILED DESCRIPTION 
     Generally, current arrangements for apparel compute devices include integrating everything into a garment or integrating sensors directly into the garment with conductive traces leading to a removable computing device or hub. A removable hub may allow for ease in charging a battery, for example, as well as reducing manufacturing costs by, for example, not having to guard against a washing environment (e.g., the hub is removed prior to washing the garment). Hub connections in removable arrangements are typically achieved via two or more conductive snap connectors or a pocket sewn into the garment and a wired connection. 
     As wearable computing devices become smaller and more tightly integrated with garments, there is a need for an attachment method that holds the compute device securely without using connecting snaps prevalent in the industry because snaps tend to be large with respective to fabric surface area as well as “high” or “tall” holding the compute device away from the fabric surface. These problems with current fastening devices may be addressed via a magnetic coupling with a physical arrangement to enforce an orientation of the apparel compute device and the garment. Thus, the special interference of snaps is avoided while still maintaining the detachable nature of the apparel compute device as well as enforcing positional arrangements to improve performance of the apparel compute device when attached to the garment. 
       FIGS. 1A and 1B  illustrate use of the apparel compute device connection with a shirt, according to an embodiment.  FIG. 1A  illustrates a front view of a shirt and  FIG. 1B  illustrates the same shirt from the rear. The connector seat  105  of the base is bonded to the shirt. The base also includes a connector extending through the connector seat. An exterior portion  110  of the base connector provides an electrical interface to a corresponding exterior portion on the apparel compute device  115  when the apparel compute device is seated. The apparel compute device  115  includes a magnetic layer (obscured) to hold it in place. The magnetic layer is a magnet or responsive to a magnetic field (e.g., ferrous metals) to hold the apparel compute device  115  in place. In an example, the cap  120  contains a magnet or magnetic layer to provide a magnetic field, or respond to a magnetic field generated by the magnetic layer, to hold the apparel compute device  115  in place. In an example, the cap  120  is removable. In an example, the cap  120  is not removable (e.g., is bonded to the garment). 
     The exterior portion  110  of the base connector and the exterior portion of the apparel compute device connector enforce an arrangement of the apparel compute device  115  with respect to the garment. One or both of the exterior portions include an outward extension. In an example, one exterior portion includes corresponding depressions to the outward extension of the mating pair such that they “plug” into each other. The extent of this pairing, however, may not provide sufficient friction holding between the pieces in order to, for example, minimize the profile of the apparel compute device  115  when seated. In an example, both of the exterior portions include outward extensions that interlock (e.g., fit side-by-side). In any case, the arrangement of the portions is such that an orientation of the apparel compute device  115  with respect to the connector seat  105  is enforced when seated. 
     An interior portion of the apparel compute device connector (not shown) is electrically connected to the exterior portion and to a computer contained in a housing of the apparel compute device  115 . Thus, when seated, the computer is electrically connected to at least one element integrated in the garment via the exterior portions and the interior portion of the base (e.g., node seat). 
     Thus, in an example, the illustrated attachment device may be arranged with three main components, a small, encapsulated computing node (e.g., apparel compute device  115 ), a node seat (e.g., the connector seat  105 ), and a magnetized cap (e.g., cap  120 ). The node  115  houses the processor and electronics, a battery, a thin metal plate, and physical connectors that attach to the garment sensor system. The node seat  105  provides a stable base for connecting the node  115  to the garment. The seat  105  is permanently bonded to the garment and enables electrical contact with the garment&#39;s sensing system. The magnetic cap  120  has a strong internal magnet that attracts the node&#39;s metal plate through the seat  105  and garment fabric, thereby holding the node  115  securely in place. The magnetized cap  120  is permanently bonded to the outside of the garment. 
     The magnetic connection enables a apparel compute device  115  to be designed with a much lower profile than those with snap-attachments, further enabling it to be worn comfortably inside a garment. The magnetic attachment also enables the compute device  115  to be attached without the use of an internal pocket, which has the advantage of allowing the compute device  115  sensors to reside close to the skin without a fabric barrier. The compute device  115  is easy to tend to by the user and may be attached without visual inspection by feeling the connection “snap” into the proper position when the connector pins are physically engaged. 
     The small, permanently magnetized cap  120  is washable. The cap  120  may be designed to reflect the manufacturer&#39;s brand including logos, colors, or specific shapes or materials. Thus, the garment maintains a clean aesthetic appearance whether or not the compute device  115  is attached as the connectors may remain hidden inside the garment. 
       FIG. 2  illustrates a block diagram of an exploded assembly of an apparel compute device connection, according to an embodiment. The elements  260  comprise an example of the apparel compute device  115 , the elements  265  comprise an example of the base  105 , garment surface  245 , and traces (e.g., wires)  240  integrated into the garment surface  245 , and the elements  270  comprise an example of the cap  120 . 
     The apparel compute device  260  (e.g., node) includes a housing  225 , a computer  220  (e.g., electronics), a battery  215 , and a magnetic layer  205 . The magnetic layer  205  includes one or more apertures  210  for conductive material to extend through the metal surface  205 . The conductor includes an interior portion (e.g., interior with respect to housing  225 ) that has an interface (e.g., bus, wire, plug, etc.) to the computer  220  contained in the housing  225 . The conductor also includes an exterior portion that includes a conductive structure extending perpendicular to the magnetic layer  205  and arranged to orient the magnetic layer  205  (and also the housing  225  if it is immovably bonded to the magnetic layer  205 ) when connected to the base  230 . The orientation arranged may be achieved with a single conductive structure based on its shape. That is, if the shape is asymmetrical in one direction, it will not be reversible in that direction. In an example, one or more additional conductive structures (e.g., as illustrated three conductive structures are used). These additional structures may provide additional functionality (e.g., signal, power, clock, etc.) and may also facilitate orientation of the magnetic layer  205  with respect to the base  230  when seated. 
     In an example, the conductive structures of the connector have at least one of a width or length greater than a height. Here, length and width are measured in the plane of the magnetic layer  205  and height is measured perpendicular to that surface (e.g., the height is the degree to which the exterior portion extends inwards or outwards from the magnetic layer  205 ). This arrangement provides for a low profile interface while increasing conductive surface area contact with an exterior portion  235  of the base connector. In an example, the exterior portion of the conductor extends outwards from the magnetic layer  205  (e.g., it is a post or tine). In an example, the exterior portion extends inwards from the magnetic layer  205  (e.g., it is a depression or socket). In an example, the magnetic layer  205  or the housing  225  includes an edge (e.g., a lip, ridge, groove, etc.) arranged to position the magnetic layer  205  with regard to the seat  230 . For example, given exterior portions for the apparel compute device  260  and the base connector  235  that both extend outwards, a rotational orientation may be enforced by the exterior portions alone (e.g., the straight line-like exterior portions must align for the seating to take place, but they may slip along that rotational orientation. The edge of the magnetic layer  205 , in this example, will operate to prevent such a slip. 
     The connector seat  230  is arranged to accept the conductor (e.g., exterior portion) from the apparel compute device  260  via a connector extending through the connector seat  230 . In an example, the connector seat  230  is not magnetic or responsive to a magnetic field. For example, the conductor is not conductive, a ferrous metal, or a magnet. In an example, the connector seat  230  is bonded to the garment  245 . Example bonding may include being sewn, glued, fused, welded, or otherwise paired to the garment  245  in a substantially permanent manner (e.g., generally understood to not be detachable during normal use). 
     The connector includes an interior portion that has an interface to conductive lines  240  incorporated into the garment  245 . The connector also includes an exterior portion  235  that includes a conductive structure extending perpendicular to the connector seat  230 . In an example, the exterior portion  235  extends outwards from an exterior surface of the connector seat  230  (e.g., outward with respect to fabric  245 ). In an example, the exterior portion  235  extends inwards from an exterior surface of the connector seat  230 , forming a depression in the surface of connector seat  230 . 
     The cap  270  includes a housing  255  and a magnet  250  held by the housing  255 . In an example, the housing  255  is bonded to the garment  245  perpendicular to the connector seat  230  and on a different surface that that of the connector seat  230 . This is the arrangement illustrated in  FIG. 2 , where the cap  270  is behind the seat  230  on the other side of the garment  245 . In an example, the housing  255  includes a removable cap allowing access to, and thus removal of, the magnet  250 . 
       FIGS. 3A and 3B  illustrate an assembly of the apparel compute device connection with a shirt, according to an embodiment.  FIG. 3A  illustrates one side of a fabric surface of the garment  315  while  FIG. 3B  illustrates the other side of the fabric surface. The assembled apparel compute device  310  includes the exterior portion  305  of its conductor that mates with the exterior portion  325  of the base connector extending through the connector seat  320 . Again, the interior portion of the base connector interfaces with wiring  330  embedded in the garment  315 . 
     The cap housing  335  is bonded to the garment  315  behind the seat  320  (illustrated here via the wires  330 ) and holds the magnet  335 . The interaction between the magnet  335  and the magnetic layer of the apparel compute device  310  provides the force to hold the apparel compute device  310  in place while minimizing the profile (e.g., height) of the apparel compute device  310 . 
       FIGS. 4A and 4B  illustrate seating, according to an embodiment.  FIG. 4A  illustrates a seating in which both the apparel compute device conductor exterior portion  410  and the base connector exterior portion  235  extend outward from their respective magnetic layer  205  and seat  230 . As shown, such a seating provides an electrical connection from the base connector interior portion  415  to the computer  220  via the base connector exterior portion  235 , the conductor exterior portion  410 , and the conductor interior portion  405 .  FIG. 4B  illustrates the same concept as  FIG. 4A  except that, in this case, the base connector exterior portion extends inwards from the seat  230  rather than outwards. This arrangement may have an additional benefit of omitting raised connector ends that may discomfort a user when worn without the apparel compute device  225  being seated. 
       FIG. 5  illustrates an example of a method  500  to implement an apparel compute device connection, according to an embodiment. 
     At operation  505 , a connector with a magnetic layer and an exterior portion of a conductor is provided. 
     At operation  510 , a base with exterior of a connector is provided. The combination of the exterior of the connector and the exterior of the conductor enforcing an orientation constraint between the base and an apparel compute device when seated in the base. 
     At operation  515 , the base is bonded to a fabric surface (e.g., of a garment). 
     At operation  520 , conductive lines (e.g., traces) of the garment (e.g., or bag, tent, etc.) are connected to the interior portion of the base connector. 
     At operation  525 , the connector for the apparel compute device may be seated into the base via the magnetic layer, the connector exterior portion, and the base exterior portion. In an example, seating the connector includes inserting the connector exterior portion into the base exterior portion to complete a circuit. In an example, seating the connector includes inserting the base exterior portion into the connector exterior portion to complete a circuit. In an example, where both the connector exterior portion and the base exterior portion respectively extend outwards from the magnetic layer and from the connector seat, seating the connector includes meshing the connector exterior portion and the base exterior portion to complete a circuit. 
     At operation  530 , the conductive lines of the computer in the apparel compute device are connected to the conductive lines of the garment via the connector conductor and the base connector. 
     In an example, the method  500  may be extended by providing a housing bonded to the garment perpendicular to the connector seat and on a different surface of a fabric to which the connector seat is bonded and providing a magnet held by the housing. In an example, the housing includes a removable cap, the removable cap, when removed, permitting removal of the magnet. 
       FIG. 6  illustrates a block diagram of an example machine  600  upon which any one or more of the techniques (e.g., methodologies) discussed herein may perform. In alternative embodiments, the machine  600  may operate as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine  600  may operate in the capacity of a server machine, a client machine, or both in server-client network environments. In an example, the machine  600  may act as a peer machine in peer-to-peer (P2P) (or other distributed) network environment. The machine  600  may be any machine capable of executing instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein, such as cloud computing, software as a service (SaaS), other computer cluster configurations. 
     Examples, as described herein, may include, or may operate by, logic or a number of components, or mechanisms. Circuitry is a collection of circuits implemented in tangible entities that include hardware (e.g., simple circuits, gates, logic, etc.). Circuitry membership may be flexible over time and underlying hardware variability. Circuitries include members that can, alone or in combination, perform specified operations when operating. In an example, hardware of the circuitry may be immutably designed to carry out a specific operation (e.g., hardwired). In an example, the hardware of the circuitry may include variably connected physical components (e.g., execution units, transistors, simple circuits, etc.) including a computer readable medium physically modified (e.g., magnetically, electrically, moveable placement of invariant massed particles, etc.) to encode instructions of the specific operation. In connecting the physical components, the underlying electrical properties of a hardware constituent are changed, for example, from an insulator to a conductor or vice versa. The instructions enable embedded hardware (e.g., the execution units or a loading mechanism) to create members of the circuitry in hardware via the variable connections to carry out portions of the specific operation when in operation. Accordingly, the computer readable medium is communicatively coupled to the other components of the circuitry when the device is operating. In an example, any of the physical components may be used in more than one member of more than one circuitry. For example, under operation, execution units may be used in a first circuit of a first circuitry at one point in time and reused by a second circuit in the first circuitry, or by a third circuit in a second circuitry at a different dine. 
     Machine (e.g., computer system)  600  may include a hardware processor  602  (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory  604  and a static memory  606 , some or all of which may communicate with each other via an interlink (e.g., bus)  608 . The machine  600  may further include a display unit  610 , an alphanumeric input device  612  (e.g., a keyboard), and a user interface (UI) navigation device  614  (e.g., a mouse). In an example, the display unit  610 , input device  612  and UI navigation device  614  may be a touch screen display. The machine  600  may additionally include a storage device (e.g., drive unit)  616 , a signal generation device  618  (e.g., a speaker), a network interface device  620 , and one or more sensors  621 , such as a global positioning system (GPS) sensor, compass, accelerometer, or other sensor. The machine  600  may include an output controller  628 , such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NEC), etc.) connection to communicate or control one or more peripheral devices (e.g., a printer, card reader, etc.). 
     The storage device  616  may include a machine readable medium  622  on which is stored one or more sets of data structures or instructions  624  (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions  624  may also reside, completely or at least partially, within the main memory  604 , within static memory  606 , or within the hardware processor  602  during execution thereof by the machine  600 . In an example, one or any combination of the hardware processor  602 , the main memory  604 , the static memory  606 , or the storage device  616  may constitute machine readable media. 
     While the machine readable medium  622  is illustrated as a single medium, the term “machine readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions  624 . 
     The term “machine readable medium” may include any medium that is capable of storing, encoding, or carrying instructions for execution by the machine  600  and that cause the machine  600  to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions. Non-limiting machine readable medium examples may include solid-state memories, and optical and magnetic media. In an example, a massed machine readable medium comprises a machine readable medium with a plurality of particles having invariant (e.g., rest) mass. Accordingly, massed machine-readable media are not transitory propagating signals. Specific examples of massed machine readable media may include: non-volatile memory, such as semiconductor memory devices (e.g., Electrically Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. 
     The instructions  624  may further be transmitted or received over a communications network  626  using a transmission medium via the network interface device  620  utilizing any one of a number of transfer protocols (e.g., frame relay, interne protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communication networks may include a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile telephone networks (e.g., cellular networks), Plain Old Telephone (POTS) networks, and wireless data networks (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards known as Wi-Fi®, IEEE 802.16 family of standards known as WiMax®), IEEE 802.15.4 family of standards, peer-to-peer (P2P) networks, among others. In an example, the network interface device  620  may include one or more physical jacks (e.g., Ethernet, coaxial, or phone jacks) or one or more antennas to connect to the communications network  626 . In an example, the network interface device  620  may include a plurality of antennas to wirelessly communicate using at least one of single-input multiple-output (SIMO), multiple-input multiple-output (MIMO), or multiple-input single-output (MISO) techniques. The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding or carrying instructions for execution by the machine  600 , and includes digital or analog communications signals or other intangible medium to facilitate communication of such software.

Moreover, the present inventors also contemplate examples using any combination or permutation of those elements shown or described (or one or more aspects thereof), either with respect to a particular example (or one or more aspects thereof), or with respect to other examples (or one or more aspects thereof) shown or described herein. 
     All publications, patents, and patent documents referred to in this document are incorporated by reference herein in their entirety, as though individually incorporated by reference. In the event of inconsistent usages between this document and those documents so incorporated by reference, the usage in the incorporated reference(s) should be considered supplementary to that of this document; for irreconcilable inconsistencies, the usage in this document controls. 
     In this document, the terms “a” or “an” are used, as is common in patent documents, to include one or more than one, independent of any other instances or usages of “at least one” or “one or more.” In this document, the term “or” is used to refer to a nonexclusive or, such that “A or B” includes “A but not B,” “B but not A,” and “A and B,” unless otherwise indicated. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.” Also, in the following claims, the terms “including” and “comprising” are open-ended, that is, a system, device, article, or process that includes elements in addition to those listed after such a term in a claim are still deemed to fall within the scope of that claim. Moreover, in the following claims, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects. 
     The above description is intended to be illustrative, and not restrictive. For example, the above-described examples (or one or more aspects thereof) may be used in combination with each other. Other embodiments may be used, such as by one of ordinary skill in the art upon reviewing the above description. The Abstract is to allow the reader to quickly ascertain the nature of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. Also, in the above Detailed Description, various features may be grouped together to streamline the disclosure. This should not be interpreted as intending that an unclaimed disclosed feature is essential to any claim. Rather, inventive subject matter may lie in less than all features of a particular disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment. The scope of the embodiments should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
