Abstract: Some battery-powered devices, such as smartphones, can be unlocked with use of wearable NFC (Near Field Communication) authentication devices. However, using conventional NFC authentication procedures is expensive in terms of power consumption because of continual rediscovery and reauthentication of the wearable authentication device. To address this, the present inventors, devised, among other things, more efficient methods for authenticating NFC-tagged authentication device, such as rings. For example, one embodiment uses two NFC polling loops or structures, instead of one as conventionally done. The first loop, used for initial authentication, entails scanning for two or more types of NFC tags. And the second loop, invoked after initial authentication, scans for a smaller subset of the two or more types to conserve battery power.

Abstract: The present invention provides a multiple coil structure for supporting multiple types of charging and near field communications. The multiple coil structure includes an inner charging coil comprising a first conductor path forming one or more loops, wherein the direction of travel of the conductor path from an end point of the first conductor path is one of a substantially clockwise direction or a substantially counter-clockwise direction, and wherein the inner charging coil has an inner boundary and an outer boundary. The multiple coil structure further includes an outer charging coil comprising a second conductor path forming one or more loops, which extend around the outer boundary of the inner charging coil, wherein the direction of travel of the conductor path from an end point of the second conductor path is one of a substantially clockwise direction or a substantially counter-clockwise direction, and wherein the outer charging coil has an inner boundary and an outer boundary.

Abstract: A method, a personal area network device operating as a slave, and a short range communications device operating as a slave are disclosed. A data storage 208 may store at least one protocol-specific channel criterion for a connection with a master short range communication device 104. A short range transceiver 108 may execute a preliminary device scan of a scanning set of communication channels for radio frequency energy. A processor 204 may decide to execute a full device scan based in part on the protocol-specific channel criterion.

The user identification sensor is adapted for sensing a user interaction in an area proximate the back side surface of the device and receiving as part of the interaction, user identification information corresponding to a particular user presently using the device, and determining whether the user identification information corresponding to the particular user matches identification information for a predetermined authorized user.

Abstract: A near field communication (NFC) system includes a portable device having an embedded NFC antenna, an add-on module blocking the embedded NFC coil and an NFC transfer coil wrapped around the add-on module to eliminate blocking of the embedded NFC antenna. A predetermined set of NFC antenna tuning parameters is associated with each add-on module and is applied by the device's NFC controller upon identifying the docked add-on module. In an embodiment, the NFC transfer coil includes linked first and second NFC coils which replicate NFC signals in each other. The NFC transfer coil may include a ferrite shield between each of the linked NFC coils and the add-on module to minimize the creation of eddy currents that may degrade the performance of the embedded NFC antenna.
