A device may broadcast an indication of an activity level of the device. The device may also receive a notification of an incoming message and receive at least one broadcast from at least one additional device also receiving the notification of the incoming message including an indication of at least one activity level of the at least one additional device. The device may compare its own activity level with the received at least one activity level. In response to determining that the activity level of the device is equal to or greater than a highest received at least one activity level, the device may display the notification of the incoming message.

A headset system comprising a headset and a base station. Each of said headset and base station comprises a transceiver configured to transmit radio signals between said headset and said base station according to a first wireless communication protocol, and each of said headset and base station further comprises a transceiver configured to transmit radio signals between said headset and said base station according to a second wireless communication protocol. At least one of said headset and said base station further comprises selecting means, such as a protocol selector configured to select one of said first and second wireless communication protocols for transmission of radio signals between said headset and said base station. The protocol selector is adapted to select the first wireless communication protocol for transmission of voice communication and the second wireless communication protocol for transmission of media content.

A hearing device includes a processor and a wireless transceiver operatively connected with the processor and configured to connect via a wireless link with a remote device and to exchange bi-directional audio packets with the remote device. The processor is configured to monitor an audio link quality, and adapt a transmit power of the hearing device as a function of the audio link quality.

A system for a vehicle including: a bluetooth receiver configured to be installed in a vehicle and connected with an electronic system of the vehicle; and a phone including a long-range radio frequency (RF) transceiver configured to transmit signals to and receive signals from a cellular network and a bluetooth transmitter configured to communicate with the bluetooth receiver in the vehicle within a predetermined range.

In one aspect, a system for receiving communications while a user operates a motor vehicle is provided. The system may include (1) a BLUETOOTH interface configured to establish a connection to a BLUETOOTH device associated with the motor vehicle, (2) a wireless communication interface configured to receive a wireless communication from a remote device, and (3) a processor coupled to the wireless communication interface and the BLUETOOTH interface, and configured to: (a) determine the user is operating the motor vehicle based upon the connection to the BLUETOOTH device, and (b) suppress a notification of the user of receipt of the wireless communication while the user is operating the motor vehicle.

A device for connecting a phone to a vehicle, the device including: a case, the case including: a long-range radio frequency (RF) transceiver for communication with a control device in a vehicle via a long-range wireless link; and a short-range bluetooth (BT) transceiver for communicating with a smartphone via a short-range wireless link, wherein the case is configured to be attached to an external surface of the smartphone, and wherein the device is configured to relay commands from the smartphone to the vehicle.

A smart call method is applied in a smart call device, there being a first handheld device and a second handheld device containing the smart call device. The first and second handheld devices are bound and communicate with the smart call device. The smart call device receives an incoming call signal from the first handheld device and acquires images of nearby faces through an image acquisition unit in response. The first handheld device compares the acquired face images with stored user face images of the second handheld device. The smart call device sends a control signal to the first handheld device according to a successful comparison and the first handheld device calls the second handheld device bound with the smart call device.

A biological information measuring apparatus includes a sensor unit, a processing unit that detects biological information on the basis of sensor information received from the sensor unit, and a communication unit that transmits the biological information to a connection target device at a transmission speed corresponding to a scheduled transmission data amount of the biological information.

The disclosure herein provides a mobile system including a mobile base station and a wireless earbud. The base station comprising a connection hole, a user input button, at least one processor, at least one memory, and circuitry. The wireless earbud is configured for plugging into the connection hole of the base station to form an integrated body with the base station. The system establishes a wireless Bluetooth pairing between a smartphone and the wireless earbud using two-way wireless communication to produce Bluetooth communication between the smartphone and the wireless earbud.

In this application, by using a method for collaborative recording by using a mobile terminal and the true wireless stereo earbud, recording with more complete data amount can be collected, and cooperative noise reduction is performed on a recording signal collected by the mobile terminal and a recording signal collected by the true wireless stereo earbud, so that accuracy and integrity of a human voice signal obtained through separation are higher. Further, in this application, when the true wireless stereo earbud performs recoding in a mode of single-earbud recording, a data amount of the true wireless stereo earbud is relatively small. Therefore, when the mobile terminal receives, through Bluetooth, data sent by the true wireless stereo earbud, excessive occupation of Bluetooth bandwidth of the mobile terminal is avoided, and power consumption of a mobile phone is reduced.
