A method provides device access security via use of periodically changing Quick Response (QR) codes. The method includes: generating () a first authentication QR code and assigning () the generated QR code as the current authentication mechanism for accessing the device. Contemporaneously with the generation of the QR code, at least one QR code validity parameter is established () to define when access to the device can be provided to a second device that provides the correct authentication QR code along with the access request. The method includes, in response to a pre-defined trigger () of the QR code validity parameter: generating () a new authentication QR code, different from a previously generated authentication QR code; assigning () the new authentication QR code as the current authentication mechanism for accessing the device; and enabling access to the first device to only second devices that provide the current authentication QR code.

Device security utilizing continually changing QR codes

Disclosed are a system and method for moving a connection from a localized network, e.g., a personal area network ('PAN'), to a different or larger network, e.g., a wide area network ('WAN'). In one aspect, wherein two devices are in communication on a PAN, each device uses the PAN to query the IPv6 WAN prefix assigned to each other device to which it is communicating on the PAN. The querying device then creates a globally routable IPv6 address for the desired communication and uses it to continue the connection after the device detects that the PAN is out of range. In an embodiment, one of the endpoint devices may determine that it has changed its IPv6 prefix and may transmit the new prefix to the other device through an out-of-band method such as the Short Message Service.

A device-to-device (D2D) pairing assembly comprises: a first and a second device detecting and communicating (DDC) component communicatively coupled to each other and to a microprocessor that executes a device pairing parameter exchange (DPPE) utility, which configures the D2D pairing assembly to: detect a communicative coupling of a first user device to the first DDC component; receive from the first user device at least one first pairing parameter, which first pairing parameter enables another device to connect to and participate in a pairing session with the first user device; detect a communicative coupling of a second user device to the second DDC component; and communicate the at least one first pairing parameter to the second user device, via the second DDC component, to trigger the second user device to connect to and participate in a pairing session with the first user device via a direct device-to-device communication channel.

A client device encodes data into an audio signal and communicates the audio data to an additional client device, which decodes the data from the audio signal. The data is partitioned into characters, which are subsequently partitioned into a plurality of sub-characters. Each sub-character is encoded into a frequency, and multiple frequencies that encode sub-characters are combined by the client device to generate an audio signal. Frequencies encoding sub-characters may be above 16 kilohertz, so the sub-characters are transmitted using frequencies that are inaudible to humans. The audio signal is communicated to an additional client device, which decodes frequencies from the audio signal to sub-characters, which are then combined into characters by the additional client device to generate the data.

Disclosed are methods and systems for devices in peer-to-peer networks to form a new group using information sent by a group owner in a previous group session. In some embodiments, a method of delegating group ownership from a first device to a second device for the formation of a new group includes: determining the second device will be the group owner of the new group during a current group session; broadcasting to devices in the current group session that the second device will be the group owner of the new group; dissolving the current group session; and forming a new group with the second device as group owner.

A handheld portable device () receives information signals modulated over one or more radio frequency (RF) spectrums includes housing (), a user interface () and a plurality of antennae (A-A) that are configured to respond to modulated RF information signals. Receivers (RX-RX) receive the modulated RF information signals from the plurality of antennae. A controller () determines a user grip from one or more properties of the response to modulated RF signals by respective ones of the plurality of antennae and controls the user interface based on a determined user grip.

An electronic device () includes a control circuit () that is operable with a memory or storage device (). The electronic device includes an RFID tag () having a second memory (). The RFID tag can be read from, or written to, by a RFID communication device () when the electronic device is OFF. Device personalization can be achieved when the control circuit accesses the second memory to retrieve the device configuration data during a boot sequence and configures the electronic device in accordance with the device configuration data retrieved from the second memory during the boot sequence. Device information can be made available when the electronic device is OFF by writing the device information to the second memory.

A first user equipment (UE) includes a display, at least two communication mechanisms that respectively supports a first and a second communication mode, and a processor communicatively coupled to the display and the communication mechanisms. The first UE further includes a failed pairing notification (FPN) utility that configures the first UE to: initiate communication with a second UE via a first communication mode; and in response to a trigger condition indicating that the first communication mode is not supported at either the first UE or the second UE, generate a notification alerting a user of the first UE that (1) a different communication mode is required for the first UE to communicate with the second UE and (2) an authorization QR code is required to be exchanged between the first UE and the second UE as an authentication mechanism before the communication can be established via the different communication mode.

A method and system communicates a request between a user application and a modem within a wireless communication device. A radio interface layer (RIL) architecture includes an application framework which receives a hardware specific request as a first application programming interface (API) call from the user application. In response to receiving the request, the application framework sends a corresponding, second API call to a vendor radio interface layer (Vendor RIL) which provides an interface configured for communicating with a specific type of transceiver or modem. In one embodiment, the second API call is transmitted via a Java Native interface (JNI). The JNI provides access to software programs associated with the transceiver, which programs are written in a language that is different from Java. The Vendor RIL communicates with the modem using a modem protocol software corresponding to the specific type of modem to perform commands associated with the request.

Disclosed are a methods and devices in a battery-powered multimode wireless communication device () that operates pursuant to first and second communication protocols in idle and active modes. The battery power level is monitored and may drop to a predetermined threshold while operating pursuant to the first communication protocol. The device switches from the first wireless communication protocol so that the device is operating in accordance with the second communication protocol in the event that the battery power level has dropped to the predetermined threshold while operating pursuant to the first communication protocol in idle mode or in active mode.
