Disclosed are a mobile terminal and a method of controlling the same. The mobile terminal includes a display unit configured to display a content screen and a control unit configured to change an output state of the content screen with respect to a point from which a first touch gesture starts, in response to that the first touch gesture is sensed in the content screen, and when the first touch gesture which is continuously sensed in the content screen corresponds to a predetermined reference, perform control to search for other content associated with at least one piece of information extracted from the content screen.

Mobile terminal and method of controlling the same

Systems, circuits, and devices for reducing leakage current in a mobile device with an embedded battery are disclosed. In one embodiment, a system for reducing leakage current in a mobile device with an embedded battery comprises a power management integrated circuit (PMIC), a switch device electrically coupled to the embedded battery and the PMIC, and a low power personal area network (PAN) module coupled to the embedded battery, the PMIC, and the switch device. The low power PAN module is configured to maintain the switch device in an open state while an application processor (AP) of the mobile device is off and to close the switch device in response to a receipt of an AP ON request signal to wake up the AP, where the open state of the switch device blocks leakage current flowing from the battery to the PMIC.

Reduction of leakage current in mobile device with embedded battery

Systems and methods for controlling one or more sensor devices are disclosed. In one embodiment, a system of a mobile device for controlling one or more sensor devices comprises an application processor (AP), a low power personal area network (PAN) module configured to wirelessly communicate with an external device for establishing a connection with the external device, at least one sensor device, and a controller coupled to the AP, the low power PAN module and the at least one sensor device. The controller is configured to monitor a connection request signal communicated from the external device via the low power PAN module while the AP is in a sleep mode, and generate sensor data by processing each signal from the at least one sensor device during the sleep mode, where the controller is supplied with quiescent current from a battery of the mobile device during the sleep mode.

Systems and methods for controlling sensor devices in mobile devices

Systems for waking up an application processor (AP) of a mobile device are disclosed. In one embodiment, one of the systems of the mobile device includes a Bluetooth device with Bluetooth Low Energy (BLE) feature configured to receive a connection request signal from an external device and a hardware module coupled to the Bluetooth device with BLE feature. The hardware module is configured to forward an AP ON request signal received from the external device via the Bluetooth device with BLE feature if the pairing request signal is determined to be valid, and wherein the Bluetooth device with BLE feature and the hardware module are supplied with quiescent current from a battery of the mobile device prior to the wake up of the AP.

Systems for remotely waking up application processor of mobile device

A system, circuit, and device for waking up an application processor (AP) of the mobile device are disclosed. The system includes a low power personal area network (PAN) module configured to communicate with an external device for establishing a connection with the external device. The system also includes a controller for the low power PAN module configured to process a connection request signal from the external device and to wake up the AP of the mobile device in response to an AP on request signal from the external device when the connection request signal from the external device is verified as valid, where the controller is supplied with quiescent current from a battery of the mobile device prior to the wake up of the AP.

Remote wakeup of application processor of mobile device

Systems, circuits, and devices for wirelessly charging a mobile device are disclosed. In one embodiment, a system of a mobile device comprises a low power PAN module and a controller for the low power PAN module configured to monitor a connection request signal communicated from an external device while the mobile device is in a sleep mode, where the controller is supplied with quiescent current from a battery of the mobile device during the sleep mode. In addition, the system comprises an AP of the mobile device configured to wake up from the sleep mode when the connection request signal is validated by the controller, forward to the external device an equipment identity data of the mobile device and a charging status of the battery, and charge the battery of the mobile device with energy received from a wireless charging module associated with the external device.
