Definitions

  • Various embodiments disclosed herein concern wearable authentication devices, such as those incorporating Near Field Communications (NFC) technology.
  • NFC Near Field Communications
  • NFC Near Field Communications
  • NFC-tagged devices require users to try multiple times to get an NFC reader to read or detect the presence of their NFC device.
  • the problem similar to trying to insert, a key upside down into a conventional door lock, is that many users are presenting their NFC-tagged devices in a backward, sideways, or other incorrect orientation that prevents the devices from being read or recognized, thus requiring these users to repeatedly reorient their devices and re-present them for reading until successful or the users give up.
  • NFC-tagged device is actually worn by the user, for example, as a watch, ring, or necklace, its reorientation may require use of two hands, rather than one, presenting additional inconvenience and potential hazards.
  • NFC-enabled devices particularly wearable ones.
  • FIG. 1 is a plan view of an assembly for a wearable authentication device corresponding to one or more claimed embodiments.
  • FIG. 2 is a cross-sectional view of the FIG. 1 assembly through plane 2 - 2 and thus also corresponding to one or more embodiments.
  • FIG. 3 is a perspective view of wearable authentication device incorporating the FIG. 1 assembly and corresponding to one or more embodiments.
  • FIG. 4 is a cross-sectional end view of a FIG. 3 device taken along plane 4 - 4 and corresponding to one or more embodiments.
  • FIG. 5 is a block diagram of a kit or system which corresponds to one or more embodiments.
  • each of the NFC-compliant antennas which for example take the form of a planar spiral-wound coil, generates a magnetic field generally transverse or more particularly perpendicular, to an outer surface of the ring when excited with an appropriate RF signal, thereby providing the ring with multiple options for establishing an inductive coupling to the electronic device.
  • Substrate 110 has a length L of generally 60-80 millimeters and a width W of 7-10 millimeters.
  • the substrate includes multiple layers which are shown best in the cross-sectional view of FIG. 2 taken along plane 2 - 2 in FIG. 1 .
  • the layers which are formed sequentially one atop the other using known techniques, such as deposition, or alternately as separate layers that are subsequently adhered or laminated, include a metal base layer 112 , a ferrite shield layer 114 , and an insulative layer 116 .
  • Metal base layer 112 is approximately 0.4 millimeters thick, consists of a flexible, manually bendable metal, such as tin. Metal base layer 112 is adhered or laminated or otherwise joined to or deposited on ferrite shield layer 114 , which has a thickness of approximately 0.1-0.2 millimeters. Ferrite shield layer 114 , which in some embodiments comprises an iron-impregnated flexible plastic, such as mylar, provides a magnetic shielding function. Ferrite shield layer 114 supports and is adhered to insulative layer 116 . In the example embodiment, insulative layer 116 is approximately 0.1-0.2 millimeters thick and is formed of a molded mylar or other flexible and durable plastic or polymer. Insulative layer 116 supports antenna conductor 120 .
  • Antenna conductor 120 includes inductive coil elements 121 , 122 , 123 and 124 connected in series between terminal nodes 126 and 127 .
  • Inductive coil elements 121 , 122 , 123 and 124 which are spaced approximately 2-4 millimeters apart, take the form of flat rectangular spirals arranged according to the right-hand rule to produce corresponding magnetic fields transverse, for example substantially perpendicular to the surface of the insulative layer 116 (out of the page of FIG. 1 ) when conducting an electrical current in a counterclockwise direction as indicated via arrow heads 125 .
  • the rectangular coils which are substantially identical in geometry, optimized for resonance at 13.56 megahertz, each have an outermost loop that defines a CL by CW rectangle, with 4 progressively smaller and concentric rectangular turns or convolutions. The smallest or innermost turn defines a 0.5CL by 0.75CW mm rectangle. (Some embodiments use oval, circular, or other spiral geometries.)
  • the example geometry uses uniformly wide 0.25-0.5 millimeter gold, silver, copper, aluminum, or non-metallic conductors with 0.25-0.5 millimeter center-to-center spacing.
  • the coil and insulation layers are formed as a flexible printed circuit, with the coil conductors having thickness in the range of 30-100 microns. In the presence of a changing magnetic field, an antenna signal voltage is induced across terminal nodes 126 and 127 , which are coupled to respective contact pads or regions 131 and 132 of communication IC 130 .
  • Communication IC 130 which in the example embodiment takes the form of a commercially available NFC tag IC, includes, among other things, a transceiver circuit 134 and a memory 135 .
  • Transceiver circuit 134 is configured not only to recognize 13.56 megahertz signals presented by antenna conductor 120 at contact pads 131 and 132 , but also to communicate one or more portions of data stored in memory 135 , for example authentication data, as a modulated 13.56 megahertz RF signal through antenna conductor 120 to an adjacent NFC reader, such as an NFC-equipped device (not shown in this figure).
  • Memory 135 stores authentication data or information 136 .
  • the data which may be encrypted in some embodiments, includes a unique device identifier from the TAG IC of the wearable authentication device.
  • communications IC or NFC tag IC 130 is compatible with one or more NFC Forum Type 1, Type 2, Type 3 Type 4 or Type MIFARE Classic Tag standards and/or one or more of the International Standard Organization (ISO) standards: ISO/IEC14443 or with the Japanese Industrial Standard (JIS) X 6419-4.
  • ISO International Standard Organization
  • JIS Japanese Industrial Standard
  • the memory in the example embodiment, ranges in capacity from 48 bytes to 1 megabyte and the transceiver supports communication speeds from 106 kbits/s to 424 kbits/s.
  • other embodiments support alternative forms of inductive coupling and tag memory storage and communications protocols.
  • FIGS. 3 and 4 show an example wearable authentication device 300 which incorporates the teachings of FIG. 1 and takes an annular or ring-like configuration sized for a human finger or other body part.
  • device 300 takes the form of a watch, a wristband, a chain necklace, a belt and buckle, and/or other type of wearable item.
  • device 300 includes an outer layer or covering 310 , assembly 100 ′ (an annular and extended form of assembly 100 in FIG. 1 ), transverse magnetic field regions 321 - 325 and a gap 330 .
  • Outer layer or covering 310 serves as an encapsulating layer over the annular-configured assembly 100 ′, protecting it from environmental dirt, oil, and moisture.
  • the outer layer also covers the inner surfaces of assembly 100 ′ and gap 330 .
  • outer layer 310 is formed of a non-metallic material, such as mylar plastic, silicone, latex, polyurethane, or other suitable material, to permit the passage of wireless signals between the antenna and the associated device. It is envisioned that the outer material could be metallic in areas where the antenna coils need not emit, and non-metallic in areas around the coils.
  • Assembly 100 ′ in this ring-like configuration, has five coil elements 121 , 122 , 123 , 124 , and 124 ′ distributed equally and circumferentially underneath covering 310 .
  • the coils When the conductors are conducting an electrical current provided by tag IC 130 (not visible in this cross-sectional view), the coils respectively generate, according to the right-hand rule, corresponding local magnetic fields 321 , 322 , 323 , 324 , and 325 through and above covering 310 .
  • Each of these fields is not only transverse to, but also perpendicular to a corresponding surface portion of covering 310 and to a plane defined by its associated coil element.
  • Providing more than one magnetic field with this orientation provides multiple opportunities for effective inductive coupling of the ring to an NFC reader in an associated device, thereby increasing the probability of an effective authentication occurring during a given presentation of the ring or wristband to the associated device.
  • the associated device is a handheld device, such as a smart phone that has an NFC sensor positioned near its back surface, and the authentication device takes the form a ring worn on a finger of a user's hand holding the phone in a conventional manner. In this position, the ring will rest against the back surface of the handheld device and provide sufficiently strong fields that match or nearly match what is desired for peak or optimal inductive coupling to the NFC sensor.
  • FIG. 5 shows an example kit or system 599 , which includes wearable authentication device 300 of FIG. 3 and an electronic device 500 .
  • Electronic device 500 is generally representative of a personal computer, desktop computer, laptop computer, tablet computer, workstation, personal digital assistant, smart phone, mobile telephone, handheld navigation device, global positioning receiver, gaming system, media playback device, remote controller, vehicle steering wheel or structure, door handle or knob, joy stick, or any electronic device or assembly having an NFC or similar wireless communication capability and one or more features or functions for which authentication is required or desired as a prerequisite for user operation or access.

  • Power module 510 includes components and circuitry for providing power to various components of the electronic device 500 .
  • module 510 includes a power supply, one or more batteries, battery-charging circuitry, and an AC adapter module and plug (none of which are shown separately in the figure).
  • Transceiver module 520 includes one or more transceivers, transmitters, and/or receiver circuits for enabling communications with external devices, systems, and/or networks via available communications protocols. Some embodiments include circuitry for enabling personal area, local area, wide area, or metropolitan area wireless communications via one or more of the following protocols: CDMA (Code Division Multiple Access), GSM (Global System for Mobile Communications), Bluetooth, WiFi, WiMAX, GPS (Global Positioning System), LTE (Long Term Evolution), and UMTS (Universal Mobile Telecommunications System).
