In one aspect, an example method to be performed by a vehicle-based media system includes (a) receiving audio content; (b) causing one or more speakers to output the received audio content; (c) using a microphone of the vehicle-based media system to capture the output audio content; (d) identifying reference audio content that has at least a threshold extent of similarity with the captured audio content; (e) identifying visual content based at least on the identified reference audio content; and (f) outputting, via a user interface of the vehicle-based media system, the identified visual content.

A content transmission method is provided. The method may include: A first device determines that a distance between the first device and a second device is less than a distance threshold. The first device provides a user with a prompt that content transmission can be performed between the first device and the second device. The first device recognizes a gesture operation performed by the user on the first device, and determines transmission content and a transmission direction of the transmission content between the first device and the second device based on the recognized gesture operation. The first device receives the transmission content from the second device or sends the transmission content to the second device based on the determined transmission direction.

Techniques for input session between devices based on an input trigger are described and may be implemented to enable a first device (e.g., a mobile device) to serve as an input device for a second device. Generally, the described implementations enable multiple different input triggers to be utilized to trigger an input session between devices, such as for enabling proximity-based input (e.g., stylus input, touch input, etc.) to a first device to be provided as input to a second device.

A battery in a mobile phone cover may be selectively charged according to a user-selectable parameter. When charged, the battery in the mobile phone cover may be used to charge a battery in a mobile phone.

A calling system for a personal watercraft includes processing circuitry. The processing circuitry is configured to: obtain a specific state signal indicating that the personal watercraft is in a given specific state; and wirelessly transmit a calling signal based on the specific state signal.

Techniques for a controller mode for a mobile device are described and may be implemented to enable a mobile device to implement a controller mode. In the controller mode a controller graphical user interface is presented on the mobile device and is utilized to receive input to interact with application content communicated from the mobile device to a remote display device. Generally, the described implementations enable multiple controller triggers to be utilized to trigger a controller mode on a mobile device.

A system may include multiple electronic devices. A first device such as a source electronic device may supply visual content for displaying by a display in a second electronic device such as a display electronic device. The display electronic device may be a television or other device with a display. Calibration operations may be performed by taking light measurements on light produced by the display when test content is provided from the first device to the second device. A third electronic device in the system such as a portable electronic device with an ambient light sensor may make measurement on the light from the display while the test content is being displayed. The test content may contain a test image target with time-varying color and time-varying intensity, allowing calibration information such as gamma curves to be obtained on the display.

A mobile device includes a user interface having a display panel and a touch panel, a network interface to communicate with an external network, a memory to store a password and an authorized user, a functional unit to sense a user and a motion of the mobile device during a power saving mode, and a control unit to control operations of the mobile device, and to perform an unlocking operation during the power saving mode to unlock the mobile device. The unlocking operation includes a motion detection process of sensing the motion of the mobile device, a user identification process of determining that a sensed user represents the authorized user, in response to the sensed motion of the motion detecting process, and an unlocking process of unlocking the mobile device according to the determination of the user identification process.
