DETAILED DESCRIPTION OF THE INVENTION

[0054] In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of embodiments of the invention. However, it will be apparent that various embodiments may be practiced without these specific details. The figures and description are not intended to be restrictive.

[0055] The ensuing description provides exemplary embodiments only, and is not intended to limit the scope, applicability , or configuration of the disclosure. Rather, the ensuing description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing an exemplary embodiment. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims. [0056] Specific details are given in the following description to provide a thorough

understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. For example, circuits, systems, structures, processes, and other components may be shown as components in block diagram form in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, processes, algorithms, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments.

[0057] Embodiments of the present invention provide a smart platform that can be used to hold and charge mobile devices of various sizes using various systems and methods. In various embodiments, the smart platform can include a smart case used for holding a mobile device and an attachment module used for securing the smart case in a fixed position. In various embodiments of the present invention, the attachment module can be a wearable item that includes a waist strap, a pack, and a charging device may be used for holding and charging mobile devices of various types and/or sizes without creating a fixed cavity in the pack.

[0059] Numerous benefits can be achieved by way of the present invention over conventional techniques. For example, the smart platform disclosed herein can be used to hold and charge mobile devices of various sizes, rather than being limited to hold and/or charge one type of mobile device of a specific size. Furthermore, the mobile device can be held stable in an appropriate position with respect to the charging device for optimum wireless charging. In addition, because some embodiments of the wearable item include a series of small steps that can be compressed, the wearable item may be made small when the small steps are compressed, and may fit with tight clothing or fit in, for example, a pocket or a handbag.

[0060] In some embodiments, the smart platform can include a smart case coupled to an attachment module. Further, the universal coupling scheme between the smart case and the attachment module means smart platform accessories can be coupled to any mobile device disposed in a smart case. The universal coupling scheme relieves a user of purchasing new accessories each time a new mobile device is purchased. Further, in some embodiments, the smart platform offers a two in one solution to both secure and communicate with a mobile device disposed in a smart case. [0061] FIG. 1 A is a simplified side view of a smart case coupled to a plurality of smart blades according to an embodiment of the present invention. The smart case 102 can be configured to receive a mobiie device 104 such as a smart phone and provides for electrical connectivity between the mobiie device 104, the smart case 102, and a plurality of smart blades 106.

Additionally, the smart case can include coupling force elements 110 operable to couple with matching coupling force elements on an individual smart blade 108. In the embodiment illustrated in FIG. 1A, the smart case 102 is attached to the plurality of smart blades 106.

[0062] In various embodiments, the plurality of smart blades 106 can include devices, for example, to provide additional battery resources, to make and receive payments, to open and lock doors, to measure environmental conditions, to expand storage capacity, to employ a Trusted Platform Module (TPM) to support reliable methods for exchanging ciyptographic keys, to authenticate user transactions and the like. The plurality of smart blades 106 can be communicatively coupled using wireless signals and/or opposing contact arrays. In some embodiments, the plurality of smart blades 106 and the smart case 102 can be configured to transmit and/or receive power using wireless signals and/or opposing contact arrays. In other embodiments, the smart case 102 can be used with no smart blades attached to the smart case 102. Additional description related to smart blades and a system of stacked devices is provided in U.S. Patent No. 8,798,675, the disclosure of which is hereby incorporated by reference in its entirety for all purposes.

[0063] FIG. IB is a simplified plan view of the smart case 102 according to an embodiment of the present invention. FIG. IB shows the mobile device 104 inserted into the smart case 102 with a touch/display screen 112 of the mobile device 104 accessible when the device is inserted in the smart case 102. In some embodiments, the smart case 102 can include a connector element 1 14 to couple the smart case 102 to the mobile device 104. In other embodiments, the smart case 102 can communicate wirelessiy with the mobiie device 104. The smart case 102 can be configured to transmit data and/or power to the mobile device 104 using the connector element 114 or wirelessly. The connector element 1 14 can include, for example, a micro USB connector, a Lightning © connector, and the like. In some embodiments, the smart case 102 can include a battery configured to supply power to the mobile device 104.

[0064] FIG. 1 C is a simplified plan view of a first attachment surface 1 16 of a smart case 102 according to an embodiment of the present invention. As shown in FIG. 1 C, smart case 102 includes one or more coupling force elements 110 and a contact array 118. In some

embodiments, the contact array 118 can include coupling force elements configured to secure the first attachment surface 116 to a second attachment surface. The mobile device 104 disposed in the smart case 102 may be accessible through, for example, the contact array 118 and/or the coupling force elements 110 configured to provide electrical contacts. In some embodiments, the contact array 118 can comprise a set of terminals 120 characterized by a bisector 122. The terminals can be arrayed in pairs with each terminal of a pair positioned an equal distance from the bisector 122. In some embodiments, a contact array 118 can be characterized by multiple bisectors. Each individual smart blade 108 of the plurality of smart blades 106 can be provided with an attachment surface in a configuration similar to the first attachment surface 116.

[0065] The coupling force elements 110 can include one or more male adapters for attaching to an individual smart blade 108 or a second module configured to secure the smart case 102 and mobile device 104 in a fixed position. In some embodiments, coupling force element 110 can include a magnet 132 and a load pin 134. The load pin 134 can include a metal that can be magnetized. The load pin 134 can be of any suitable shape, such as a cylinder, a part of a cylinder, a bar, and the like. The size of load pin 134 may be of any suitable size in length and cross-sectional size. For example, in some embodiments, the load pin 134 may be a cylinder with a length of less than 5 mm and a diameter of less than 5 mm.

[0066] In other embodiments, the coupling force element 110 can be a female adapter configured to match a corresponding male adapter on an individual smart blade 108 or other appropriately configured second module. Female adapters can be located on the first attachment surface 1 16 of the smart case 102 opposite to male adapters on a second module. Female adapters can include a magnet having a polarity opposite to the polarity of the magnet on the male adapter and a hole that can fit a load pin on the second module. Thus, when put close to each other, the female adapter and the male adapter may attract each other and the load pin can be inserted into the hole to lock a first module {e.g., a smart case 102 or an individual smart blade 108) and a second module {e.g., a charging module) in place. In this way, the plurality of smart blades 106 can be piggybacked and do not need to be removed before bringing the first attachment surface 116 of the smart case 102 into contact with a second attachment face of a second module.

[0067] In some embodiments, the coupling force element 1 10 can be implemented using a magnet. For example, one type of magnet that can be used includes a rare earth magnet called a neodymium magnet. A Neodymium magnet can comprise Neodymium (Nd), Iron (Fe), and Boron (B). A suitable magnet size for the first attachment surface 116 can be around 4 mm x 2 mm x 1 mm. Any type of magnet can be used, including an electromagnet, typically comprised of an iron core and a winding, wherein the electromagnet is activated by passing a current through the winding. In some embodiments, opposing contact arrays comprising four such magnets in each module can have a breakaway force of approximately 1 lb., a force that is easily managed in a user's fingers. While the embodiment illustrated in FIG. 1C shows three coupling force elements, any number of coupling force elements can be used to meet the requirements of a specific application. For example, a smart case designed for use in military or industrial settings can include a higher number of coupling force elements to provide a more secure platform for a mobile device.

[0068] Additional description related to the arrangement and operation of various contact arrays and coupling force elements is provided in U.S. Patent No. 9,576,409, the disclosure of which is hereby incorporated by reference in its entirety for all purposes. In alternative embodiments, the first attachment surface can be provided without a contact array and the mobile device 104, disposed in the smart case 102, may be accessible through, for example, wireless signals. One of ordinary skill in the art would recognize many variations,

modifications, and alternatives.

[0074] Data streams and power can be transmitted between any and all combinations of the smart case 102, the plurality of smart blades 106, and the attachment module 200, including: smart case 102 to smart blades 106, smart case 102 to attachment module 200, and smart blades 106 to attachment module 200. A smart blade 108 can be defined as any device having a support function in relation to the mobile device 104. Multiple streams of data may flow simultaneously through the coupled contact array 1 18 on the first attachment surface 116 and contact array 204 on the second attachment surface 202. [0075] FIGS. 3A and 3B show various embodiments of a common contact area formed by bringing a first module with a first attachment surface into proximity of a second module with a second attachment surface. FIG. 3 A is an expanded cross-sectional view of a magnet pair interface 300 formed by bringing a first attachment surface into proximity with a second attachment surface. FIG. 3A illustrates an embodiment where the coupling force element comprises a magnet. The magnet pair interface 300 is formed by bringing a first attachment surface 304 of a first module 306 into contact with a second attachment surface 308 of a second module 310 at an interface 302. The first module 306 can include a first magnet 312 and the second module 310 can include a second magnet 314. In some embodiments, the first module 306 can be an attachable module such as a smart blade and/or a smart case similar to the structures illustrated in FIG. 1. The second module 310 can be an attachment module, similar to the structures illustrated in FIG. 2, a wearable device for securing a smart platform, and/or a second smart blade. In some embodiments, the magnet pair interface 300 can be formed by terminals of contact arrays on a first attachment surface and a second attachment surface. In other embodiments, the magnet pair interface 300 can be formed by the coupling force elements of a first attachment surface and a second attachment surface.

[0076] In some embodiments, the first module 306 may be a smart blade. A thin smart blade may have a magnet that extends from the first attachment surface 304 to an opposing attachment surface on the opposite side of the first module 306. In a relatively thick smart blade, a separate magnet can be provided on the opposing attachment surface, in other embodiments, the first magnet 312 and the second magnet 314 may be positioned within a first magnetic field containment device 316 and a second magnetic field containment device 318 respectively.

[0077] The poling 320 of the first magnet 312 and the poling 322 of the second magnet 314 provide for an attractive coupling force when the first attachment surface 304 is brought into proximity with the second attachment surface 308. The opposite polari ty of the first magnet 312 and the second magnet 314 generates a force that secures the first module 306 and the second module 310 together. Opposing magnets at the interface may be coupled or uncoupled by applying a user's fingers to the first and second devices and employing a snap-on or a snap-off action respectively. When coupled, the breakaway force between the first and second devices may be in the range of 0.1 - 4.0 pounds, a force that can be easily managed in a user's fingers. Each coupling event may be conveniently accomplished by a user, employing their fingers only, with no tools and no cables or cable connectors required. In some contexts, it may be beneficial to replace the magnet on the second side of the interface with a component other than a magnet, such as a disk comprising a material of high magnetic permeability, while retaining the snap- on/snap-off capability. [0078] In some embodiments, the first magnet 312 and the second magnet 314 can provide an electrical connection between the first module 306 and the second module 310. In various embodiments, magnet bodies can be conductive and magnets can have an electroplated outer surface that is electrically conductive. The first magnet 312 and the second magnet 314 can be used as electrical terminals. For example, the magnets can be configured to transmit data signals or power via a conductor 324 coupled to the first magnet 312 in the first module 306 and a second conductor 352 coupled to the second magnet 314 in the second module 310. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.

[0079] FIG. 3B is an expanded cross-sectional view of a terminal pair interface formed by bringing the first attachment surface 304 of the first module 306 into proximity with the second attachment surface 308 of the second module 310 at the interface 302. The terminal pair includes a first terminal 326 coupled to the first attachment surface 304 and a second terminal 328 coupled to the second attachment surface 308. The first terminal 326 can include a body of conductive rubber molded within a conductive ring 330 and the conductive ring 330 may be coupled to a conductor 332 to transmit data signals or power to an attached circuit in the first module 306. The second terminal 328 can be configured in a similar arrangement. As shown at location 334, each terminal may compress at the interface with an opposing terminal to be contained in the available space between contact arrays.

[0080] In various embodiments, other types of compliant terminals may also be used, each type typically comprising a compliant conductive member on at least one side of the interface. The terminals on the other side of the interface may comprise hard elements such as, metal disks for example. The body of the compliant terminal may comprise conductive rubber for example, as shown in FIG. 3, or it may comprise a dome-shaped deflectable conductive membrane (not shown) as a further example. POGO pins comprising spring- loaded contacts may also be used as terminals. Other types of terminals and compliant connectors will be apparent to practitioners of the art. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.

[0081] In certain contexts it may be beneficial that devices such as the first module 306 and the second module 310 illustrated in FIG. 3 are capable of communicating through the terminals and/or the magnets without the need, in some embodiments, for the use of radio frequency (RF^') signals passing between the system components. As will be evident to one of skill in the art, the presence of radio signals may present a vulnerability to detection by RF sniffer circuits for example, and this may pose a security risk to the user. Thus, embodiments of the present invention, utilizing wired communications between devices, provide solutions that are not readily available using wireless communications technology and protocols. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.

[0082] FIG. 3C shows an expanded cross-sectional view of an interface formed by a plurality of magnet pairs and the effect of magnetic field containment devices such as 316 and 318.

Magnetic field containment devices 316 and 318 are disposed between and optionally around the first magnet 340 and the second magnet 342 of a single module comprising a north pole 344 of the first magnet 340 and a south pole 346 of the second magnet 342. Typically, the magnetic field containment devices include a material of high magnetic permeability. Referring to FIG. 3C, magnetic field lines 348 pass between the magnets in each magnetic field containment device, indicating the region where the magnetic field strength is strongest. At location 350, which is located inside the first module 306, the magnetic fields produced by the first magnet 340 and the second magnet 342 are reduced, making this location suitable for placing sensitive magnetic and electronic components such as magnetometers, accelerometers, cameras, LEDs, chemical sensors, buttons, displays, connectors, switches, conductors, connector assemblies, antennas, or the like.

[0083] Using magnetic field containment devices 316 and 318, the magnetic field at location 350 due to magnets 340 and 342 may be reduced to a value such as 1% of the earth's magnetic field. The reduced field strength may be low enough to minimize and/or eliminate interference with magnetic and electronic circuits inside the host such as magnetometers and accelerometers. Devices such as the magnetic field containment device 316 also have the desirable property that they limit far field magnetic effects in a direction outward from the coupling face when a host device is not coupled to another device using the contact array. However, when the host device is coupled to another device using the contact array, the effective coupling force is not substantially diminished by the presence of magnetic field containment devices 316 and 318. This is because the magnetic pathway from a magnet to a directly contacting opposing magnet has a lower reluctance than the magnetic pathway from a magnet to a spaced apart second magnet through a magnetic field containment device such as 316.

[0084] An alternative to providing magnetic field containment devices around magnet pole pairs is to provide magnetic shielding around all components to be protected. The two approaches may also be combined. One of ordinary skill in the art would recognize many variations, modifications, and alternatives. [0085] FIG. 4A is a simplified perspective view of an attachment module with a mechanical coupling element according to an embodiment of the present invention. In some embodiments, the attachment module 400 can attach to, for example, a belt 490. The attachment module 400 can include an attachment body 402. The attachment body 402 can be configured to interface with a smart case similar to the smart case illustrated in FIG. 1. The attachment body 402 can include an attachment surface 404. The attachment body 402 and attachment surface 404 can be substantially planar.

[0086] In some embodiments, the attachment surface 404 can include one or more coupling force elements 406. One or more of the coupling force elements 406 can include a load pin 408. In other embodiments, the attachment surface 404 can be provided without coupling force elements 406. The coupling force elements 406 of attachment module 400 can be configured to interface with the coupling force elements of a smart case similar to the coupling force elements illustrated in FIGS. 1 and 2, While the embodiment illustrated in FIGS. 4A and 438 show three coupling force elements, any number of coupling force elements can be used to meet the requirements of a specific application. For example, a smart case designed for use in military or industrial settings can include a higher number of coupling force elements to provide a more secure platform for a mobile device.

[0087] In various embodiments, the attachment module 400 can include a contact array 410 disposed on the attachment surface 404. In some embodiments, the contact array 410 can include coupling force elements configured to secure a second module to the attachment surface 404. The attachment module 400 can include a removal cutout 424 to assist with removal of a smart case or smart blade that is attached to the attachment module 400. In some embodiments, the attachment module 400 can be configured with a device specific attachment body 402. A device specific attachment body 402 can include device specific cutouts such as camera/flash cutout 414. The device specific cutouts can account for a smart case, a mobile device, or a smart blade that is not planar or has features such as a fingerprint reader on the first attachment surface 116.

[0088] The coupling force elements 406 and/or the contact array 410 can be configured to resist shear movement between the attachment body 402 and a coupled module. In some embodiments, additional restraint can be provided by a mechanical coupling element 412. The attachment module 400 can include the mechanical coupling element 412 mounted on the attachment body 402. One or more fixed and/or adjustable mechanical coupling elements can be constructed in a flexible spring structure such as a spiral configuration 418. The mechanical coupling element 412 can be placed on any of the sides or edges of the attachment body 402. In other embodiments, the attachment module 400 can be provided with no mechanical coupling element 412. To provide added coupling force, the mechanical coupling element 412 can be positioned to exert a force to an attached module preferably normal to the attachment surface 404. In this configuration, the mechanical coupling element 412 can adjust to a variety of modules of varying thickness. The spiral design eliminates the need for a separate attachment body 402 for each device. The attachment module 400 can accommodate multiple modules without changing the configuration. The attachment module 400, with the mechanical coupling element 412, can secure a module with a thickness ranging from a few millimeters to tens of millimeters. Also, the spiral configuration 418 provides additional security because incidental contact with the mechanical coupling element 412 will not relieve the force normal to the attachment surface. [0089] In various embodiments, the mechanical coupling element 412 can be made of materials that provide sufficient rigidity and are light weight, for example, polycarbonate, plastic, aluminum, carbon fiber, combinations thereof, or the like. In some embodiments, at least a portion the mechanical coupling element 412 can be encapsulated by a material such as foam that is suitable to exert a force on the screen of a mobile device. The mechanical coupling element 412 is illustrated extending along a portion of the attachment body 402. In other embodiments, the mechanical coupling element 412 can be substantially the same length as the attachment body 402.

[0090] The mechanical coupling element 412 can be fixed to a first edge 416 of the attachment body 402 using a variety of mechanisms su ch as bonding an end of the mechanical coupling element 412 to the attachment body 402, sliding an end of the mechanical coupling element 412 into a receiving structure formed on an the first edge 416 so that the mechanical coupling element 412 can be removed as desired, or the like. Thus, embodiments of the present invention include implementations in which the mechanical coupling element 412 can be attached in a fixed, detachable, moveable, or flexible manner. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.

[0091] The smart holder 400 can include a positioning element similar to the positioning element illustrated and described in FIG. 2. In embodiments that include the positioning element, the smart holder 400 can be rotated to landscape mode (FIG. 4A) or portrait mode (FIG. 4B),

Attachment module 400 can include a second mechanical coupling element 420. The second mechanical coupling element 420 can be fixed to a second edge 422 of the attachment body 402 using a variety of mechanisms. In some embodiments with a moveable mechanical coupling element, the second mechanical coupling element 420 can be optional. Mechanical coupling element 412 can be moved to the second edge 422. in various embodiments, the additional restraint offered by two mechanical coupling elements may be desired and the attachment module 400 can be configured with two or more mechanical coupling elements.

[0122] FIG. 8A is a simplified perspective view of an attachment module according to an alternative embodiment of the present invention. In the implementation illustrated in FIG 8 A, ball joint 718 is coupled to attachment body 706. A connector arm 725 extends away from the ball joint. Vane connector 760 is mechanically attached to connector arm 725 using an attachment portion 766 and can be pre-formed to enable easy insertion into the air vent as well as easy locking of the vane connector around one or more vent vanes. In this figure, the vent vane would extend into the plane of the figure, passing through vane receiving region 755.

[0123] In FIG. 8A, the vane connector 760 can be pre-formed in a hook shape to facilitate looping of the vane connector 760 around the vent. In an embodiment, the vane connector 760 has a first portion 761 that is semi-rigid to rigid and can be pre-formed. The vane connector 760 also has a second portion 764 that is flexible, and in this embodiment, includes a plurality of apertures 769 operable to engage with retention stud 765. The vane connector 760 can also include an attachment portion 766 to secure the vane connector 760 to the connector arm 725. In operation, the user inserts the pre-formed hook into the space between the vent vanes until the hook clears then back of the vent vane. Then the user pulls the second portion of the vane connector, which is flexible, forward, which causes the pre-formed hook to loop around the vent vane. The second portion of the vane connector is then available to the user on an opposing side of the vent vane, who can then pull the terminal end 767 of the second portion of the vane connector toward the attachment base. In the embodiment illustrated in FIG. 8A, the apertures on the second portion are engaged with the retention stud 765 to lock the connector vane 760 in place. Embodiments of the present invention provide a smart platform car adapter that can be reliably mounted to the vent vanes, overcoming problems with conventional products that can fail off after mounting because frictional pressure between the mount and the vent vane is insufficient to prevent detachment.

The attachment module 700 includes the ball joint 718, the attachment body 706, the connector arm 725, the first portion 761 and the second portion 764 of the vane connector 760, the terminal end 767 of the vane connector 760, retention stud 765, dimples 770, one or more protrusions 734, and receiving region 755. The one or more protrusions 734 can engage the dimples 770 to lock the attachment body 706 in a desired position. [0125] FIG. 8C is a simplified perspective view of an attachment module with a plunger according to an alternative embodiment of the present invention. The ball joint 718 can include a plunger mechanism 715 that enables the user to rotate the attachment body 706 with respect to the connector arm 725. In operation, the user pushes on the attachment body, which allows the base of the ball joint to move away 784 towards the vane connector 760, thereby creating space between the protrusions 734 on the socket 714 of the ball joint 71 8 and the dimples 770 on the ball 716, allowing the end user to rotate the attachment body to a desired direction. Once the user achieves the desired position for the attachment body 706 (and smartphone, tablet, computer, or the like), the user releases the attachment body 706, which pushes the ball 716 of the ball joint 71 8 (for example, using a plunger 71 5) into a locking position on the dimples 770 of the ball. These dimples 770, which can be implemented by a variety of jagged surfaces, are designed to allow any position to have a locking position and support heavy weight. The plunger 715 can include a force exerting element such as a preformed plastic material, a metal spring, and the like.
