An article of headgear to be worn on the head of a user includes a first portion to encompass at least a portion of the head of the user and a visor extending forward from the first portion. The visor includes a laterally extending opening therein to receive a personal communication device including a camera such that a lens of the camera is positioned below the lower surface of the visor.

Aspects of the subject disclosure may include, for example, responsive to a first registration request to access a mobile network, determining whether a first phone number associated with a first IMSI assigned to a first SIM of a first mobile device matches a second phone number associated with a second IMSI assigned to a second SIM of a second mobile device, determining whether the second mobile device is currently registered to the mobile network, and, in turn, sending a request for authentication to register the first mobile device and to deregister the second mobile device, determining whether a response to the request for the authentication code matches an authentication code, and responsive to the determining the response matches the authentication code, registering the first mobile device to the mobile network and deregistering the second mobile device from the mobile network. Other embodiments are disclosed.

Systems and methods are presented for establishing a communication link between two or more electronic devices. A portable eyewear electronic device is configured to communicate with a handheld electronic device, such as a ring, that in turn is retained by an accessory electronic device to establish a wired communication link. The accessory electronic device may be retained or housed by a second accessory electronic device, such as a remote control or wearable device.

A wearable computing device reads near-invisible one- or two-dimensional barcodes having a size of 100 microns to one millimeter. The device includes a magnifying lens, a digital camera, a processor, program memory and a wireless communication module, all supported on a wearable device body. The wearable device body may be an eyeglass frame, a watch body or wristband, a headband or sweatband or a cap or other headgear, among other possibilities. Applications of the wearable computing device include unattended shopping in a physical retail store.

A portable communication device cooperation system includes a slave portable communication device that can communicate with a master portable communication device. Each of a plurality of slave-side slots of a slave-side storage unit included in the slave portable communication device stores a slave application program transferred from a master-side slot disposed in the master portable communication device. The slave application program includes part of information of a master application program, and causes the slave portable communication device to operate by being executed by a slave-side control unit of the slave portable communication device. As a result, the portable communication device cooperation system, the master portable communication device, and the slave portable communication device exhibit an effect of enabling the slave portable communication device to be variously used.

A wireless device can store account identifiers and facilitate transactions. The wireless device can be loaded with user account identifiers and can be presented to various checkpoint devices. When presented, the wireless device can transmit a selected account identifier to the checkpoint device. In the context of a purchase transaction, the checkpoint device can be a point-of-sale terminal and the account data can be financial account data. In some instances, the wireless device can also facilitate a purchase transaction, e.g., by obtaining information about products to be purchased, constructing a purchase order from the product information, and transmitting the purchase order to a point-of-sale terminal.

Impedance matching in tunable circuits promotes consistent, high-efficiency wireless communication signal despite changing environmental conditions.

A phone grip attachment includes a base configured for attachment to a phone and a finger-hold attached to the base. The finger-hold has a top member and a bottom member. The finger-hold is movable between an extended position in which an opening is defined between the top member and the bottom member for use in gripping the phone and a collapsed position in which the top member is substantially flat against the bottom member. The finger-hold can be biased to the extended position. The finger-hold can be rotatably attached to the base.

An eyewear frame (10) comprising: - a central portion (12) configured to receive at least one optical lens (14a, 14b), - a first temple (16a) having a first embedded electronic device (18a) and a first battery (20a), - a second temple (16b) having a second embedded electronic device (18b) and a second battery (20b), the first temple (16a) is pivotably fixed to a first end (22a) of the central portion (12) and second temple (16b) is pivotably fixed to a second end (22b) of the central portion (12), wherein the first electronic and the second electronic devices (18a, 18b) are configured to communicate in a wireless manner, and the first and second electronic devices (18a, 18b) comprise each a close-range communication system (24a, 24b) configured to synchronize the first and the second electronic devices (18a, 18b).

The present disclosure relates in a first aspect to a head-wearable hearing instrument comprising first and second portions and a radio-frequency data communication interface configured to transmit and receive data packets at transmit and receipt time slots, respectively, through a wireless communication channel. The head-wearable hearing instrument comprises a connector assembly configured to electrically and mechanically interconnect the first portion with the second portion. The second portion comprises a sensor configured to measure a physical property and generate sensor data representative of the measured physical property. The head-wearable hearing instrument further comprises a wired data communication link extending between the first and second portions through the connector assembly for transmission of sensor data during transmit time slots. Said transmit time slots of the sensor data and at least said receipt time slots of the wireless communication channel are non-overlapping in time.
