Accessory devices are described herein. An accessory device may include a receptacle for receiving an electronic device. The accessory device may include a case that covers the housing of the electronic device, or a folio that additionally includes a cover can conceal the display of the electronic device. Accessory devices described herein further include wireless circuitry used to communicate with wireless circuitry in the electronic device. The wireless circuitry can be used for various functions and features. For instance, the wireless circuitry in the accessory device can respond to authentication requests from the electronic device, and/or to send authentication requests to the electronic device. Further, the wireless circuitry in the accessory device can send information to the electronic device. Such information may include properties of the accessory device, or information stored on the accessory device that is presented on a display of the electronic device.

Various aspects include wearable audio devices enabling modular component attachment and detachment. In certain implementations, a wearable audio device includes: a headband for contacting a head of a user; an earpiece coupled with the headband for positioning proximate an ear of the user, the earpiece having an electro-acoustic transducer configured to output audio signals; and a slot configured to engage an electronic component, where the slot includes one or more snap-fit and/or friction-fit connectors for selectively engaging the electronic component.

A communication apparatus, a communication system, a related method, and a server device is disclosed. The communication apparatus comprises a communication device, a sensor interface device comprising a sensor interface configured to connect with a plurality of sensor devices including a first sensor device and a second sensor device, a memory, and a processing unit. The processing unit is configured to: obtain first sensor data via a first sensor interface of the sensor interface; obtain second sensor data via a second sensor interface of the sensor interface; and determine user data based on the first sensor data and the second sensor data.

Systems and methods using a network of wearable devices to support secure payment for a user are described. The network of wearable devices may include a wearable secure unit including a first short-range transceiver, a wearable sensory unit including a second short-range transceiver, and a wearable communication unit including a third short-range transceiver and a long-range transceiver. The systems and methods may include receiving a transaction request from a merchant device. Thereafter, the systems and methods may obtain information from the wearable secure unit configured to provide an environment in which processes and data are securely stored and executed. The systems and methods may also obtain information from the wearable sensory unit configured to capture and compare biometrics of the user with a stored profile. Based on the obtained information, the systems and methods may instruct the wearable communication unit to transmit to the merchant device user authentication data.

A communication system includes a plurality of full duplex transceiver assemblies each having an ON condition and an OFF condition, and configured to be worn by a different user, each of the plurality of full duplex transceiver assemblies having a housing and printed circuit board coupled to the housing, the printed circuit board including a transceiver having a microprocessor. Each microprocessor is configured to emit a different stream of controlling data when the plurality of full duplex transceiver assemblies are in the ON condition, thereby allowing each of the plurality of full duplex transceiver assemblies to communicate among a plurality of different logical channels. Embedded with each different stream of controlling data is a unique identification number for grouping each of the plurality of full duplex transceiver assemblies together.

A wearable device includes a frame and a magnetic coupler opening formed in the frame. Wearable device further includes a processor, a memory accessible to the processor, and a very high frequency (VHF) radio transceiver for data transmission and reception and connected to the processor. Wearable device further includes a magnetic coupler connected to the VHF radio transceiver. Magnetic coupler includes a diamagnetic material shaped to form a VHF transmission or reception terminal that partially or fully aligns with the magnetic coupler opening. During transmission, magnetic coupler is configured to radiate transmitted VHF band radio modulated signals into tissue of the user. During reception, magnetic coupler is configured to absorb received VHF band radio modulated signals from the tissue of the user.

In certain embodiments, a personal network of devices including one or more wearable devices and one or more other devices may facilitate secure payment. In some embodiments, a first device of the personal network may be configured to store a plurality of virtual slots, where each of the plurality of virtual slots stores a virtual token associated with a financial account. A second device of the personal network may be configured to transmit, to a merchant device, user authentication data and a first virtual token stored in a first virtual slot to cause the merchant device to obtain information related to a financial account associated with the first virtual token to facilitate a payment transaction. Each of the first, the second device, and at least one other device of the personal network may include a short-range transceiver configured to relay information to one another as part of the personal network.

Disclosed is a mobile terminal having a differentiated structure from the conventional one. The mobile terminal includes a neck band unit configured to be wearable on a user's neck, and having a main power supply unit; and a glass unit having a frame configured to be wearable on a user's head, having an input/output module installed at the frame, and electrically-connectable to the neck band unit so as to be provided with power from the main power supply unit, wherein the neck band unit is provided with accommodation recesses formed such that at least part thereof corresponds to the frame, and wherein the glass unit is coupled to the neck band unit when two ends thereof are inserted into the accommodation recesses, respectively, and wherein the glass unit is separated from the neck band unit when the two ends thereof are withdrawn from the accommodation recesses, respectively.
